# Card Game Engine — 麻将规则引擎
|
||||
|
||||
YAML DSL 驱动的麻将规则引擎。目标：一份 DSL 配置文件 = 一种麻将玩法，
|
||||
引擎加载后自动运行，不需要写玩法特定代码。
|
||||
|
||||
## 项目结构
|
||||
|
||||
```
|
||||
card-game-engine/
|
||||
├── docs/
|
||||
│ ├── architecture-plan.md # 架构设计文档
|
||||
│ └── demo-implementation-plan.md # Demo 实施计划

|
||||
└── Demo/ # 控制台 Demo
|
||||
```
|
||||
|
||||
## 核心设计
|
||||
|
||||
- 规则引擎 ≠ 游戏引擎：纯逻辑库，不依赖图形框架
|
||||
- 扑克/麻将引擎分离：各自 100% 覆盖，共享基础层
|
||||
- int 编码：性能优先，4 bytes/tile
|
||||
- 加载时能力检查：DSL 声明 requires，引擎自动验证
|
||||
|
||||
## 开源参考
|
||||
|
||||
- q_algorithm (C# 胡牌算法库)
|
||||
- majiang_algorithm (Java 麻将引擎 + AI)
|
||||
- MahjongKit (Python 牌谱分析)

# 棋牌规则引擎 — 架构设计与研究计划
|
||||
|
||||
> **关联文档**: Demo 实施计划见 `docs/demo-implementation-plan.md`
|
||||
>
|
||||
> **目标:** 构建一套 YAML DSL 驱动的棋牌规则引擎。引擎按 DSL 编排执行，不依赖 LLM。LLM 是可选的 DSL 生产工具。
|
||||
|
||||
**核心理念:** "玩法即配置"——一个 YAML 文件 = 一种棋牌玩法，引擎加载后自动运行。不需要为每种玩法写代码。
|
||||
|
||||
**技术栈:** C# (规则引擎，嵌入 Unity game server) + Python (AI 陪打服务) + YamlDotNet (DSL 解析)
|
||||
|
||||

|
||||
|
||||
## 一、问题定义
|
||||
|
||||
### 1.1 当前痛点
|
||||
|
||||

|
||||
- 扑克类：斗地主、跑得快、炸金花、牛牛、十三张...每地变种数十种
|
||||
- 麻将类：四川血战、广东鸡平胡、日本立直、国标...规则差异在番型/计分/流程
|
||||
- 地方棋类：各种地方象棋变种、对角棋、五子棋变种
|
||||
|
||||
传统做法：每种玩法需要策划写规则文档→开发读文档手写代码→测试。周期 2-4 周/玩法。
|
||||
|
||||
### 1.2 LLM 的机会
|
||||
|
||||
LLM 在以下方面有优势：
|
||||
- 自然语言理解：从非结构化规则描述中提取结构化信息
|
||||
- 代码生成：将结构化规则转为可执行逻辑
|
||||
- 策略生成：基于规则生成陪打 AI 的决策逻辑
|
||||
|
||||
LLM 的劣势（需要解决）：
|
||||
- 幻觉：生成的代码可能有逻辑错误
|
||||
- 安全性：生成的代码不能直接执行在生产环境
|
||||
- 一致性：多次生成结果可能不同
|
||||

|
||||
|
||||
## 二、架构设计
|
||||
|
||||
### 2.0 关键架构决策：规则引擎 ≠ 游戏引擎
|
||||
|
||||
棋牌游戏的本质分两层，**它们是正交的**：
|
||||
|
||||
| 层 | 职责 | 与玩法关系 |
|
||||
|---|------|-----------|
|
||||
| **规则引擎** | 发牌算法、牌型匹配、出牌校验、回合流转、计分结算 | 每种玩法不同，LLM DSL 驱动的核心 |
|
||||
| **游戏引擎** | 牌面渲染、动画、音效、用户输入捕获、房间管理 | 完全通用，与玩法无关 |
|
||||
|
||||
这意味着：
|
||||
- 规则引擎是一个**纯逻辑库**（C#），不依赖任何图形框架。输入游戏状态 → 输出合法操作/新状态。可以脱离前端独立测试。
|
||||
- 前端引擎（Cocos/Phaser/Unity/自研 Canvas）只管"画牌"和"收点击"，从规则引擎拿状态，把用户操作喂回去。
|
||||
- **换游戏引擎不需要动规则引擎，换玩法不需要动游戏引擎。**
|
||||
|
||||
所以选型重点不在"哪个游戏引擎好"，而在**规则引擎的 DSL 表达力**。游戏引擎可以先用最轻量的方案（C# 控制台原型），后期再换 Unity。
|
||||
|
||||
**更重要的是：规则引擎本身不依赖 LLM。** LLM 只是生产 DSL 配置文件的一种方式——你也可以手写 yaml、从模板生成、或者用 GUI 配置器。规则引擎是纯逻辑系统，输入 DSL 配置 → 输出游戏行为。
|
||||
|
||||
### 2.0b 关键架构决策：扑克引擎与麻将引擎分离
|
||||
|
||||
扑克和麻将在算法层面是**两类完全不同的问题**，硬合并会导致两边都做不干净：
|
||||
|
||||
| | 扑克 | 麻将 |
|
||||
|---|---|---|
|
||||
| 核心算法 | 牌型模式匹配：从手牌中找顺子/炸弹/三带二等组合 | 面子分解：14 张牌拆成 4 组面子（顺子/刻子）+ 1 对将 |
|
||||
| 操作模式 | 轮流出牌，同一时间只有一人在操作 | 有人出牌后，多人可能同时碰/杠/胡，需要优先级仲裁 |
|
||||
| 手牌变化 | 出牌减少，动态变化 | 摸牌后出牌，保持 13/14 张恒定 |
|
||||
| 计分特点 | 底分 × 倍数，线性公式 | 番型叠加，组合计算 |
|
||||
| 牌库 | 52-54 张，固定 | 108-144 张，各地区不同 |
|
||||
| 回合结构 | 固定：叫地主→出牌→结算 | 灵活：摸→出→吃碰杠胡→查叫→血战 |
|
||||
|
||||
**决策：共享基础层 + 各自专项引擎。**
|
||||
|
||||
```
|
||||

|

```
|
||||
|
||||
分离后的覆盖率：
|
||||
|
||||
- **扑克引擎**：斗地主/炸金花/牛牛/跑得快/掼蛋/德州/21点/十三水/升级/桥牌/UNO — **100%**
|
||||
- **麻将引擎**：四川血战/广东鸡平胡/国标/日本立直/武汉麻将/长沙麻将 — **100%**
|
||||
- 各自不需要为对方做妥协，DSL 字段各取所需，不需要一套字段同时表达"炸弹"和"番型"
|
||||
|
||||
不分离的代价：PatternMatcher 必须同时理解"斗地主的飞机带翅膀"和"麻将的听牌判断"，validator 要兼容"跟牌型必须更大"和"碰杠胡优先级仲裁"，两个领域都渗漏。分开后各自精专，基础层共享避免重复。
|
||||
|
||||
### 2.0c 覆盖率深度验证：以四川麻将血战到底为例穷举分析
|
||||
|
||||
光说"麻将引擎能到 100%"是空话。必须把一条条规则拆开，逐条验证声明式 DSL 能不能兜住，兜不住的怎么办。
|
||||
|
||||
下面以 **四川麻将血战到底**（牌库 108 张、缺一门、血战、查叫查花猪）为例穷举所有规则需求：
|
||||
|
||||
#### 规则清单与覆盖分析
|
||||
|
||||
```
|
||||
一、牌库 (108张万条筒) → DeckManager 声明式 ✅
|
||||
二、发牌 (庄14闲13) → deal phase 声明式 ✅
|
||||
三、缺一门检查 (不能三色) → validator chain ✅
|
||||
四、基本胡牌 (4面子+1对将) → 需要内置算法 🔧
|
||||
五、七对胡 (7个对子) → 内置算法的分支 🔧
|
||||
六、听牌判断 (缺一张能胡) → 内置算法 🔧
|
||||
七、番型识别 (清一色/对对胡..) → 内置算法输出番型列表 🔧
|
||||
八、番型互斥 (清一色⊃无字) → DSL 互斥图 📐
|
||||
九、番型叠加计分 → DSL 番型表 📐
|
||||
十、杠 (明杠/暗杠/加杠/杠补) → 子状态机 📐
|
||||
十一、碰 (跳摸牌) → 状态机转移 ✅
|
||||
十二、优先级仲裁 (胡>杠>碰) → priority_policy ✅
|
||||
十三、血战到底 (胡后不结束) → elimination phase 📐
|
||||
十四、查叫/查花猪 (流局检查) → 结算前钩子 📐
|
||||
十五、过水 (胡过必须等一轮) → dirty_flag 📐
|
||||
十六、多人同时胡/碰 → 时序+优先级矩阵 📐
|
||||
```
|
||||
|
||||
- ✅ 已覆盖，纯声明式
|
||||
- 🔧 需要内置算法（声明式做不到，但算法是通用的）
|
||||
- 📐 声明式可覆盖，但需要扩展 DSL 字段
|
||||
|
||||
#### 🔧 内置算法：这是"声明式做不到"的部分
|
||||
|
||||
**胡牌判断算法**是无法声明式表达的。14 张牌能否拆成 4 面子 + 1 对将，本质是一个**回溯搜索**：
|
||||
|
||||
```
|
||||
输入: [1万,1万,1万, 2万,3万,4万, 5条,5条,5条, 6筒,6筒,6筒, 8条,8条]
|
||||
输出: Melds = [{type:"kezi", tiles:[1万×3]}, {type:"shunzi", tiles:[2,3,4万]},
|
||||
{type:"kezi", tiles:[5条×3]}, {type:"kezi", tiles:[6筒×3]}]
|
||||
Pair = [8条, 8条]
|
||||
IsWin = true
|
||||
```
|
||||
|
||||
这个算法是麻将引擎的**唯一算法核心**，但它跟玩法无关——斗地主不需要、扑克不需要。实现一次，所有麻将玩法共用。
|
||||
|
||||
算法复杂度：回溯搜索，最坏 O(3^n)，但手牌只有 14 张 + 剪枝优化，实际 < 1ms。
|
||||
|
||||
**听牌判断**是胡牌判断的子问题：对 13 张手牌，尝试每张可能摸到的牌，检查能否胡。
|
||||
|
||||
**番型识别**以面子分解（melds）为输入：
|
||||
|
||||
```csharp
|
||||
// 面子分解已经完成了，番型只需"看"
|
||||
var fanList = new List<string>();
|
||||
|
||||
if (melds.All(m => m.Suit == melds[0].Suit) && pair.Suit == melds[0].Suit)
|
||||
fanList.Add("清一色");
|
||||
|
||||
if (melds.All(m => m.Type == "kezi"))
|
||||
fanList.Add("对对胡");
|
||||
|
||||
if (melds.All(m => m.Tiles.Any(t => t.Rank == 1 || t.Rank == 9))
|
||||
&& (pair[0].Rank == 1 || pair[0].Rank == 9)) // 将牌也需带幺九
|
||||
fanList.Add("带幺九");
|
||||
// ...
|
||||
```
|
||||
|
||||
**关键：胡牌判断是算法；番型识别是"基于算法输出的声明式规则"。**
|
||||
|
||||
#### 📐 需要扩展 DSL 的部分
|
||||
|
||||
**番型互斥图：**一个番型可能包含另一个，需要显式声明"不计"关系：
|
||||
|
||||
```yaml
|
||||
fan_types:
|
||||
- name: "清一色"
|
||||
base_fan: 4
|
||||
excludes: ["无字", "缺一门"] # 清一色必然无字、必然缺一门
|
||||
|
||||
- name: "暗七对"
|
||||
base_fan: 4
|
||||
excludes: ["门清", "单钓将"] # 七对必然门清、必然单钓
|
||||
conflicts: ["对对胡"] # 和七对互斥
|
||||
|
||||
- name: "杠上开花"
|
||||
base_fan: 1
|
||||
excludes: ["海底捞月"] # 杠补牌≠最后一张
|
||||
|
||||
- name: "对对胡"
|
||||
base_fan: 2
|
||||
conflicts: ["暗七对"]
|
||||
|
||||
- name: "金钩钓"
|
||||
base_fan: 2
|
||||
excludes: ["单钓将"] # 金钩钓就是只剩一张，不计单钓
|
||||
```
|
||||
|
||||
计分时：先采集所有满足的番型列表 → 去掉被 `excludes` 排除的 → 检查 `conflicts` 互斥只留一个 → 累加番数。
|
||||
|
||||
**血战到底的特殊 phase：**
|
||||
|
||||
```yaml
|
||||
phases:
|
||||
- name: "play"
|
||||

|
||||

|
||||

|

|

|

|
||||
```
|
||||
|
||||
**查叫/查花猪 — 结算前钩子：**
|
||||
|
||||
```yaml
|
||||
scoring:
|
||||
pre_hooks:
|
||||
- name: "check_hua_zhu" # 先查花猪
|
||||
condition: "deck_exhausted"
|
||||
action: |
|
||||
// 检查未胡的人是否三种花色都有
|
||||
for p in alive_players:
|
||||
if countSuits(p.hand) == 3:
|
||||
// 花猪赔三家
|
||||
penalty = total_score / alive_players.count
|
||||
- name: "check_ting" # 再查叫
|
||||
condition: "deck_exhausted AND not hua_zhu"
|
||||
action: |
|
||||
for p in alive_players:
|
||||
if not isTing(p.hand):
|
||||
// 不听牌赔听牌的人
|
||||
```
|
||||
|
||||
**过水 dirty_flag：**
|
||||
|
||||
```yaml
|
||||
phases:
|
||||
play:
|
||||
state:
|
||||
fu_flag: # 过水标记
|
||||
type: "dirty_flag"
|
||||
set_on: "can_win_but_pass"
|
||||
clear_on: "next_discard_self" # 自己打出下一张牌后清除
|
||||
effect: "block_win_on_current_tile" # 本张牌不能再胡
|
||||
```
|
||||
|
||||
#### 总结：真正需要"代码"的部分
|
||||
|
||||
| 类型 | 数量 | 实现方式 | 跨玩法复用 |
|
||||
|------|------|---------|-----------|
|
||||
| 纯声明式 DSL | ~40% | YAML 配置 | 100% |
|
||||
| 扩展 DSL 字段 | ~30% | YAML + 新字段（互斥图/钩子/sub_phase） | 100%（设计一次所有麻将共用） |
|
||||
| 内置通用算法 | ~20% | C# 实现（胡牌判断/听牌/面子分解） | 100%（所有麻将玩法用同一个算法） |
|
||||
| gameplay hook | ~10% | DSL 引用的 custom 函数 | 按需（查花猪/查叫/特殊计分） |
|
||||
|
||||
**关键洞察：胡牌判断算法是唯一的"硬骨头"，但它写一次后所有麻将玩法共用。** 其余 80% 都是声明式 DSL + 扩展字段。这正是分离设计的好处——麻将引擎的 PatternMatcher 就是 `MeldsSolver`，不需要兼容扑克。
|
||||
|
||||
### 2.0d 0 bug 策略：如何保证正确性
|
||||
|
||||
规则引擎是确定性系统，这意味着可以做到 100% 测试覆盖。
|
||||
|
||||
**策略1：算法层穷举测试**
|
||||
|
||||
胡牌判断是最易出 bug 的地方。测试策略：
|
||||
|
||||
```csharp
|
||||
// 1. 正例：已知胡牌的手牌
|
||||
[Theory]
|
||||
[InlineData(new[]{1,1,1, 2,3,4, 5,5,5, 6,6,6, 8,8}, true)] // 标准胡
|
||||
[InlineData(new[]{1,1, 2,2, 3,3, 4,4, 5,5, 6,6, 7,7}, true)] // 七对胡
|
||||
[InlineData(new[]{1,1,1, 2,2,2, 3,3,3, 4,4,4, 5,5}, true)] // 碰碰胡
|
||||
public void TestWinDetection(int[] tiles, bool expected) { ... }
|
||||
|
||||
// 2. 反例：不满足胡牌条件
|
||||
[Theory]
|
||||
[InlineData(new[]{1,2,3, 4,5,6, 7,8,9, 2,2,2, 3,3}, false)] // 多一张
|
||||
[InlineData(new[]{1,1,1, 2,3,5, 7,8,9, 2,2,2, 3,3}, false)] // 缺顺子
|
||||
public void TestNotWin(int[] tiles, bool expected) { ... }
|
||||
|
||||
// 3. 穷举：所有清一色听牌组合（已知组合数）
|
||||
// 所有碰碰胡组合
|
||||
// 所有混一色组合
|
||||
// → 生成器 + 断言
|
||||
```
|
||||
|
||||
**策略2：番型互斥图形式化验证**
|
||||
|
||||
```
|
||||
加载 DSL → 构建番型互斥有向图 →
|
||||
检查: 无循环依赖
|
||||
检查: excludes 指向的番型确实存在
|
||||
检查: conflicts 双向对称
|
||||
→ 不通过则拒绝加载 DSL
|
||||
```
|
||||
|
||||
**策略3：状态机死锁/活锁检测**
|
||||
|
||||
```
|
||||
加载 phase 定义 → 构建状态转移图 →
|
||||
检查: 所有状态可达
|
||||
检查: 无孤立节点
|
||||
检查: 所有路径都能到达 end state
|
||||
→ 模拟 1000 局随机路径
|
||||
```
|
||||
|
||||
**策略4：确定性断言**
|
||||
|
||||
规则引擎的每个决策都可以写成单元测试：
|
||||
|
||||
```csharp
|
||||
[Fact]
|
||||
public void 杠上开花_自摸_番型计算_验证() {
|
||||
// 构造已知状态 → 模拟摸到最后一张 → 判定胡牌 → 验证番型
|
||||
var state = CreateState(/* 手牌+已碰+已杠+剩余牌 */);
|
||||
state.DrawCard(/* 最后一张牌 */);
|
||||
var result = engine.CheckWin(state);
|
||||
|
||||
Assert.True(result.CanWin);
|
||||
Assert.Contains("杠上开花", result.Fans);
|
||||
Assert.Contains("清一色", result.Fans);
|
||||
Assert.DoesNotContain("海底捞月", result.Fans); // 互斥
|
||||
Assert.Equal(5, result.TotalFan); // 1(杠开)+4(清一色)
|
||||
}
|
||||
```
|
||||
|
||||
**策略5：模糊测试**
|
||||
|
||||
```csharp
|
||||
// 连续随机生成 10000 局麻将，做不变量检查：
|
||||
for (int i = 0; i < 10000; i++) {
|
||||
var room = RandomMahjongGame();
|
||||
|
||||
// 不变量1: 总牌数始终 = 108
|
||||
Assert.Equal(108, totalCards(room));
|
||||
|
||||
// 不变量2: 听牌判断 → 缺一张能胡 → 实际摸到那张牌确实能胡
|
||||
foreach (var p in room.Players) {
|
||||
var tingList = engine.CheckTing(p.Hand);
|
||||
foreach (var tile in tingList) {
|
||||
Assert.True(engine.CanWin(p.Hand + tile));
|
||||
}
|
||||
}
|
||||
|
||||
// 不变量3: 番型互斥正确
|
||||
var fans = engine.CalculateFans(state);
|
||||
AssertNoConflictViolation(fans, rules.FanExclusionGraph);
|
||||
}
|
||||
```
|
||||
|
||||
**结论：0 bug 不是一个目标，是一个工程纪律。** 规则引擎是确定性系统——每个输入对应唯一输出。只要做到：算法穷举测试 + 番型互斥图形式化验证 + 状态机可达性检查 + 10000 局模糊测试不变量，就能保证正确性。
|
||||
|
||||
真正的风险不在算法，在**规则描述的错误**——人写的 DSL 配置本身可能有逻辑漏洞。所以需要模拟 1000 局 + 人工审核，而不是依赖 LLM 直接生成就上线。
|

|
||||
- ✅ = 纯声明式或内置算法已覆盖
|
||||
- 🔧 = 需要增加内置算法分支（写一次所有玩法共用）
|
||||
- - = 该玩法不适用此规则
|
||||
|
||||
#### 三种引擎能力的差距
|
||||
|
||||
**四川血战覆盖 16/16 = 100%**（不需要 🔧，因为无鬼牌无全不靠等特殊牌型）
|
||||
|
||||
**广东鸡平胡覆盖 18/19 = 95%**，唯一缺口：
|
||||
- 🔧 鬼牌/百搭牌——需要在 MeldsSolver 中支持 wildcard。胡牌判断时，wildcard 可以充当任何牌。这是算法层的通用能力，广东麻将、台湾麻将、日本麻将（赤宝牌不算百搭但性质类似）都需要。
|
||||
|
||||
**国标麻将覆盖 18/20 = 90%**，两个缺口：
|
||||
- 🔧 **全不靠**：14 张牌之间没有任何关联（无对子、无面子、无相同花色顺序），是一种完全不同的胡牌条件。当前 MeldsSolver 基于"面子分解"模型，全不靠不适用。需要增加独立的全不靠判断分支。
|
||||
- 🔧 **一色双龙会**：手牌由一种花色的 1-9 各两张组成（共 18 张，实际只有 14 张可用），需要特定的面子识别逻辑。是面子分解变体，当前算法稍作扩展即可支持。
|
||||
|
||||
**结论：三种麻将平均覆盖 95%。Demo 已扩展至四种（+武汉麻将验证 wildcard），4 种麻将全部 100% 覆盖。** 完全未覆盖的只有 3 个算法分支：鬼牌支持、全不靠、一色双龙会——这些已全部纳入 Demo 引擎扩展。其余全部是声明式 DSL + 已有内置算法。
|
||||
|
||||
#### 国标麻将 81 番种互斥关系验证
|
||||
|
||||
这是对 DSL 互斥图机制的最大压力测试。81 个番种之间有不计/不得重复/必然包含等关系，能否用 `excludes` + `conflicts` 表达？
|
||||
|
||||
抽样验证几个典型互斥：
|
||||
|
||||
```yaml
|
||||
fan_types:
|
||||
# 88番级
|
||||
- name: "大四喜"
|
||||
base_fan: 88
|
||||
excludes: ["圈风", "门风", "三风"] # 由四个风刻组成，不计各风刻
|
||||
|
||||
- name: "大三元"
|
||||
base_fan: 88
|
||||
excludes: ["双箭刻"] # 三个箭刻，不计单个箭刻
|
||||
|
||||
- name: "十三幺"
|
||||
base_fan: 88
|
||||
excludes: ["五门齐", "门前清", "单钓将", "混幺九"]
|
||||
conflicts: ["七对"] # 与七对互斥（虽然手牌像但不是七对）
|
||||
|
||||
- name: "连七对"
|
||||
base_fan: 88
|
||||
excludes: ["七对", "门前清", "单钓将", "清一色", "无字"]
|
||||
|
||||
# 64番级
|
||||
- name: "小四喜"
|
||||
base_fan: 64
|
||||
excludes: ["三风"] # 三风刻不计
|
||||
|
||||
- name: "小三元"
|
||||
base_fan: 64
|
||||
excludes: ["双箭刻"]
|
||||
|
||||
- name: "字一色"
|
||||
base_fan: 64
|
||||
excludes: ["碰碰和", "全带幺", "混幺九", "缺一门"]
|
||||
|
||||
# 48番级
|
||||
- name: "一色四同顺"
|
||||
base_fan: 48
|
||||
excludes: ["一色三同顺", "四归一", "一般高"]
|
||||
|
||||
# 1番级
|
||||
- name: "一般高"
|
||||
base_fan: 1
|
||||
# 被上级番型排除，自身不排除别人
|
||||
|
||||
- name: "连六"
|
||||
base_fan: 1
|
||||
|
||||
- name: "老少副"
|
||||
base_fan: 1
|
||||
```
|
||||
|
||||
81 番种的互斥关系大约 200+ 条 `excludes` 声明。DSL 机制可以表达——互斥图本身是数学上的有向无环图（DAG），引擎加载时做形式化验证：
|
||||
|
||||
```
|
||||
加载 → 构建 excludes 图 →
|
||||
✓ 检查无循环（A⊃B⊃C⊃A = 错误）
|
||||
✓ 检查 excludes 目标是有效番型
|
||||
✓ 检查 conflicts 双向对称
|
||||
✓ 检查番种分级（level 1-12）正确
|
||||
→ DSL 加载通过 ✅
|
||||
```
|
||||
|
||||
**这不是引擎能力问题，是 DSL 编写的工作量问题。**
|
||||
|
||||
#### 总结：麻将引擎实际覆盖率
|
||||
|
||||
```
|
||||
四川血战 广东鸡平胡 国标 日本立直 武汉 长沙 平均
|
||||
声明式 DSL 9/16 9/19 11/20 (预估) (预估) (预估)
|
||||
内置算法(已有) 7/16 7/19 6/20
|
||||
内置算法(需增加) 0 1(wildcard) 2(全不靠/双龙会)
|
||||
扩展 DSL 字段 0/16 2/19 1/20
|
||||
────────────────────────────────────────────────────
|
||||
覆盖率 100% 95% 90% ~95% ~100% ~100% ~97%
|
||||
```
|
||||
|
||||
**国标的 90% 缺口不是架构问题——全不靠和一色双龙会加进 MeldsSolver 就 100% 了。广东的鬼牌同理。这三个分支总共不超过 500 行代码。写一次，所有需要它们的玩法共用。**
|
||||
|
||||
真正的工作量不在引擎，在**81 个番种的 DSL 互斥声明**——这是数据录入工作，需要懂国标麻将规则的人逐条写 200+ 条 `excludes` 关系。但这是 DSL 配置层面的，跟引擎能力无关。
|
||||
|
||||
### 2.0e-b 宝牌冲击分析：wildcard 不止是"加一个分支"
|
||||
|
||||
当前三个 Demo 玩法（四川血战、广东鸡平胡、国标麻将）都不涉及宝牌。但宝牌是中国地方麻将中非常普遍的特性，必须在引擎设计阶段就考虑清楚，不能事后硬塞。
|
||||
|
||||
#### 宝牌在各地方麻将中的具体表现
|
||||
|
||||
| 地方麻将 | 宝牌名称 | 机制 | 来源 |
|
||||
|---------|---------|------|------|
|
||||
| 广东麻将 | 鬼/百搭 | 开牌前翻一张牌，下一张是鬼，可替代任何牌 | 随机翻牌 |
|
||||
| 武汉麻将 | 癞子 | 红中固定为癞子 | 固定 |
|
||||
| 日本立直 | 宝牌(dora) | 指示牌下一张为宝牌，不替代，只计番 | 翻宝牌指示器 |
|
||||
| 台湾麻将 | 花牌当百搭 | 摸到花牌可选择当百搭用 | 花牌 |
|
||||
| 长沙麻将 | 将将胡 | 2/5/8 固定为万能 | 固定 |
|
||||
| 东北麻将 | 会牌 | 开牌翻一张，同点数四种花色都是宝 | 翻牌 × 4 |
|
||||
|
||||
有两种本质上不同的宝牌：
|
||||
|
||||
1. **替代型 (wildcard)**：可以充当任意牌凑面子/将牌，直接影响胡牌判断（广东/武汉）
|
||||
2. **计分型 (dora)**：不替代，只额外计分/计番（日本立直）
|
||||
|
||||
**替代型宝牌才是真正威胁引擎的。** 计分型宝牌只是 ScoreEngine 的一个额外计分项，不冲击核心算法。
|
||||
|
||||
#### 替代型宝牌对 MeldsSolver 的冲击
|
||||
|
||||
回溯搜索的复杂度是 O(3^n)，n=14时约 1000 次递归。加入宝牌后：
|
||||
|
||||
```
|
||||
每张宝牌有 K 种替代可能（K = 可用牌种数）
|
||||
如果手牌中有 w 张宝牌：搜索空间 = O(3^(14-w) × K^w)
|
||||
|
||||
w=1, K=27: 3^13 × 27 ≈ 1,594,323 × 27 ≈ 4300万 ← 勉强可接受
|
||||
w=2, K=27: 3^12 × 729 ≈ 531,441 × 729 ≈ 38.7亿 ← 不可接受
|
||||
w=3, K=27: ≈ 3.5万亿 ← 完全爆炸
|
||||
```
|
||||
|
||||
**这不能用回溯直接搜索。**
|
||||
|
||||
#### 解决方案：分层处理 + 剪枝
|
||||
|
||||
不是让每张宝牌尝试所有 27 种替代。而是：**先用非宝牌完成确定性分解，再用宝牌填坑。**
|
||||
|
||||
```
|
||||
算法流程：
|
||||
|
||||
输入: 14张牌，其中 w 张是宝牌 (tag: wildcard)
|
||||
|
||||
Step 1: 分离宝牌和非宝牌
|
||||
nonWildcards = tiles.Where(t => !IsWildcard(t))
|
||||
wildcards = tiles.Where(t => IsWildcard(t))
|
||||
|
||||
Step 2: 先用非宝牌完成回溯搜索
|
||||
result = TryExtractMelds(nonWildcards, remainingWildcards = w)
|
||||
// 但在这个过程中，遇到"差一张"的情况时，用宝牌填补
|
||||
|
||||
Step 3: 回溯搜索变体——"缺口填充式"
|
||||
TryExtractMeldsWithWildcards(tiles, wildcardCount):
|
||||
1. 标准回溯，但当找不到刻子或顺子时：
|
||||
2. 如果 wildcardCount > 0：尝试用宝牌补齐
|
||||
- 补齐刻子（差1张）：消耗 1 个宝牌
|
||||
- 补齐刻子（差2张）：消耗 2 个宝牌
|
||||
- 补齐顺子（缺少中间张）：消耗 1 个宝牌
|
||||
3. 如果找不到将牌且 wildcardCount >= 2：用2个宝牌做将
|
||||
|
||||
Step 4: 剩余宝牌
|
||||
如果步骤 3 后还有剩余宝牌，它们无法单独组成面子
|
||||
必须作为已有刻子的第4张（杠材）或附加到顺子尾部
|
||||
```
|
||||
|
||||
**优化关键：把"宝牌替代27种"的穷举问题转化为"差一张就用宝牌补"的缺口填充。** 搜索复杂度从 O(27^w) 降到 O(w × 2^w)：
|
||||
|
||||
```
|
||||
w=1: O(1 × 2^1) = O(2) ← 原来的 0.5ms 几乎不变
|
||||
w=2: O(2 × 2^2) = O(8) ← 原来的 38.7亿 → 8 次递归
|
||||
w=3: O(3 × 2^3) = O(24) ← 原来的 3.5万亿 → 24 次递归
|
||||
```
|
||||
|
||||
**这是可行的。** 但需要显著改造 MeldsSolver 的 `TryExtractMelds` 方法。
|
||||
|
||||
#### 宝牌对 DSL 的影响
|
||||
|
||||
新增 `wildcard_rules` 区段：
|
||||
|
||||
```yaml
|
||||
# 广东麻将翻鬼
|
||||
wildcard_rules:
|
||||
type: "flip" # 翻牌型宝牌
|
||||
trigger: "before_deal" # 发牌前翻
|
||||
mechanism: "next_card" # 翻开的牌的下一张是鬼
|
||||
wildcard_encoding: 50 # int 编码: 50-59 为宝牌
|
||||
count: 4 # 4张鬼牌（翻出的牌每种花色各1张）
|
||||
behavior: "substitute" # 替代型
|
||||
scoring:
|
||||
per_wildcard: 1 # 每张鬼牌 1 番
|
||||
|
||||
# 武汉麻将癞子（固定型）
|
||||
wildcard_rules:
|
||||
type: "fixed"
|
||||
tiles: ["红中"] # 红中固定为癞子
|
||||
wildcard_encoding: 50
|
||||
behavior: "substitute"
|
||||
scoring:
|
||||
per_wildcard_in_win: 2 # 胡牌时每张癞子 2 番
|
||||
|
||||
# 日本立直宝牌（计分型，不替代）
|
||||
wildcard_rules:
|
||||
type: "indicator" # 指示器型
|
||||
mechanism: "flip_indicator" # 翻宝牌指示器
|
||||
behavior: "scoring_only" # 不替代，只计分
|
||||
scoring:
|
||||
per_dora: 1 # 每张宝牌 1 番
|
||||
ura_dora: "riichi_only" # 里宝牌（立直后翻）
|
||||
```
|
||||
|
||||
#### 宝牌对番型判断的影响
|
||||
|
||||
宝牌组成的面子如何计算番型？有两种处理方式，需要在 DSL 中配置：
|
||||
|
||||
```yaml
|
||||
wildcard_rules:
|
||||
fan_calculation_policy: "minimize" # 宝牌按最低番型计
|
||||
# 或者
|
||||
fan_calculation_policy: "optimal" # 宝牌按最优番型计（更易清一色等）
|
||||
```
|
||||
|
||||
举例：手牌有"清一色"潜质 + 1 张宝牌——如果宝牌也算同花色，清一色成立。"optimal" 策略会让清一色更容易达成。
|
||||
|
||||
#### 宝牌对牌面编码的扩展
|
||||
|
||||
当前 int 编码：万1-9=1-9，条=11-19，筒=21-29，字=31-37，花=41-48。
|
||||
|
||||
新增宝牌编码区间：
|
||||
|
||||
```csharp
|
||||
public static class MahjongTile
|
||||
{
|
||||
// ... 原有编码 ...
|
||||
|
||||
// 宝牌区间: 50-59
|
||||
public const int WildcardBase = 50;
|
||||
public static bool IsWildcard(int tile) => tile >= 50 && tile <= 59;
|
||||
|
||||
// 扩展 AllTiles 支持宝牌
|
||||
public static int[] AllTiles(bool includeHonors = false,
|
||||
bool includeFlowers = false,
|
||||
int wildcardCount = 0)
|
||||
{
|
||||
// ... 原有逻辑 ...
|
||||
// 末尾追加 wildcardCount 张宝牌
|
||||
for (int i = 0; i < wildcardCount; i++)
|
||||
tiles[idx++] = WildcardBase + i;
|
||||
return tiles;
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### 对 Demo 计划的影响
|
||||
|
||||
宝牌支持**已纳入 Demo**（武汉麻将红中癞子）。引擎已实现 wildcard 缺口填充式回溯：
|
||||
|
||||
| 层面 | Demo 实现 | 扩展更多宝牌变种时 |
|
||||
|------|-------------------|----------------|
|
||||
| MahjongTile 编码 | 已有 wildcard 区间预留 | ✅ 无需改 |
|
||||
| MeldsSolver.CheckWin | 缺口填充式回溯 | 翻鬼/百搭/dora 等变种 |
|
||||
| MeldsSolver.TryExtractMelds | 有 `wildcardCount` 参数 | 无需改 |
|
||||
| DSL 格式 | 有 `wildcard_rules` 字段（武汉癞子） | 增加更多宝牌模式 |
|
||||
| CapabilityRegistry | 已注册 `meldsolver.wildcard` | 无需改 |
|
||||
| ScoreEngine | 癞子计分 (`per_wildcard_in_win`) | 翻鬼计分、dora 计分 |
|
||||
| 番型互斥图 | `fan_calculation_policy: "optimal"` | 无需改 |
|
||||
|
||||
**结论：宝牌对引擎的冲击是可控的。** 核心挑战在 MeldsSolver 的回溯搜索需要从"枚举替代"改为"缺口填充"，复杂度从指数降到线性。**Demo 已通过武汉麻将验证 wildcard 缺口填充式回溯。** DSL 和编码层面已预留扩展点（翻鬼、百搭、dora 等宝牌变种）。
|
||||
|
||||
### 2.0f 加载时能力检查机制：让引擎自省
|
||||
|
||||
既然 DSL 的覆盖分析可以手工做（就像上面三张表），那就应该把它**做成引擎加载时的自动检查**，而不是每次人工排查。
|
||||
|
||||
#### 机制设计
|
||||
|
||||
**第一步：引擎声明自己的能力清单**
|
||||
|
||||
引擎启动时注册所有已实现的算法能力：
|
||||
|
||||
```csharp
|
||||
// CapabilityRegistry.cs — 引擎启动时自动注册
|
||||
engine.RegisterCapability(new Capability {
|
||||
Id = "meldsolver.standard_win",
|
||||
Name = "标准胡牌判断 (4面子+1对)",
|
||||
Category = "mahjong",
|
||||
Since = "1.0.0"
|
||||
});
|
||||
|
||||
engine.RegisterCapability(new Capability {
|
||||
Id = "meldsolver.seven_pairs",
|
||||
Name = "七对胡判断",
|
||||
Category = "mahjong",
|
||||
Since = "1.0.0"
|
||||
});
|
||||
|
||||
engine.RegisterCapability(new Capability {
|
||||
Id = "meldsolver.thirteen_orphans",
|
||||
Name = "十三幺判断",
|
||||
Category = "mahjong",
|
||||
Since = "1.0.0"
|
||||
});
|
||||
|
||||
engine.RegisterCapability(new Capability {
|
||||
Id = "meldsolver.wildcard",
|
||||
Name = "鬼牌/百搭牌支持",
|
||||
Category = "mahjong",
|
||||
Since = "2.0.0" // 还没实现就不注册
|
||||
});
|
||||
```
|
||||
|
||||
已有能力 15 项：
|
||||
|
||||
```
|
||||
meldsolver.standard_win 标准胡牌判断
|
||||
meldsolver.seven_pairs 七对胡
|
||||
meldsolver.thirteen_orphans 十三幺
|
||||
phase.mahjong_turn 麻将回合 (摸→打→碰杠胡)
|
||||
phase.parallel_elimination 并行淘汰 (血战)
|
||||
phase.priority_arbitration 优先级仲裁 (胡>杠>碰>吃)
|
||||
phase.pass_turn 过水/跳过摸牌
|
||||
deck.generator_poker 标准扑克生成器
|
||||
deck.generator_mahjong 标准麻将生成器
|
||||
deck.flower_cards 花牌处理
|
||||
scoring.expression 表达式计分
|
||||
scoring.table 查表计分
|
||||
scoring.fan_exclusion 番型互斥图
|
||||
scoring.pre_hooks 结算前钩子
|
||||
dsl.dirty_flag 过水标记
|
||||
```
|
||||
|
||||
**第二步：DSL 声明自己需要的算法能力**
|
||||
|
||||
DSL 顶部显式声明这个玩法依赖哪些引擎能力：
|
||||
|
||||
```yaml
|
||||
# doudizhu.yaml
|
||||
game:
|
||||
type: "poker"
|
||||
engine_type: "poker"
|
||||
|
||||
requires:
|
||||
- "deck.generator_poker" # 54张标准扑克
|
||||
- "pattern.single"
|
||||
- "pattern.pair"
|
||||
- "pattern.straight"
|
||||
- "pattern.bomb_4"
|
||||
- "pattern.rocket"
|
||||
- "phase.auction" # 叫地主竞价
|
||||
- "phase.turn_based"
|
||||
- "scoring.expression" # 底分×倍数
|
||||
```
|
||||
|
||||
```yaml
|
||||
# xuezhandaodi.yaml
|
||||
game:
|
||||
type: "mahjong"
|
||||
engine_type: "mahjong"
|
||||
|
||||
requires:
|
||||
- "deck.generator_mahjong" # 108张万条筒
|
||||
- "meldsolver.standard_win" # 标准胡牌判断
|
||||
- "meldsolver.seven_pairs" # 七对支持
|
||||
- "phase.mahjong_turn" # 摸→打→碰杠胡
|
||||
- "phase.parallel_elimination" # 血战到底
|
||||
- "phase.priority_arbitration" # 优先级仲裁
|
||||
- "scoring.fan_exclusion" # 番型互斥
|
||||
- "scoring.pre_hooks" # 查叫查花猪
|
||||
```
|
||||
|
||||
```yaml
|
||||
# guobiao.yaml
|
||||
game:
|
||||
type: "mahjong"
|
||||
engine_type: "mahjong"
|
||||
|
||||
requires:
|
||||
- "deck.generator_mahjong"
|
||||
- "deck.flower_cards"
|
||||
- "meldsolver.standard_win"
|
||||
- "meldsolver.seven_pairs"
|
||||
- "meldsolver.thirteen_orphans"
|
||||
- "meldsolver.all_orphans" # 全不靠 ← 🔧 还没注册!
|
||||
- "meldsolver.combo_dragon" # 组合龙 ← 🔧 还没注册!
|
||||
- "meldsolver.double_dragon" # 一色双龙会 ← 🔧 还没注册!
|
||||
- "phase.mahjong_turn"
|
||||
- "phase.priority_arbitration"
|
||||
- "scoring.fan_exclusion"
|
||||
```
|
||||
|
||||
**第三步：加载时自动检查**
|
||||
|
||||
```csharp
|
||||
// DslLoader.cs
|
||||
public RuleSet Load(string yamlPath) {
|
||||
var dsl = YamlDotNet.Parse(yamlPath);
|
||||
var required = dsl["requires"].ToArray();
|
||||
var missing = new List<string>();
|
||||
|
||||
foreach (var capId in required) {
|
||||
if (!engine.Capabilities.Has(capId)) {
|
||||
missing.Add(capId);
|
||||
}
|
||||
}
|
||||
|
||||
if (missing.Any()) {
|
||||
throw new CapabilityMissingException(

👉 补完算法分支后，更新 CapabilityRegistry，DSL 即可加载。
|
||||
```
|
||||
|
||||
#### 这个机制的价值
|
||||
|
||||
**之前**：开发者写了一个新玩法 DSL → 运行时出奇怪 bug → 花 2 小时排查 → 发现是引擎缺某个算法 → 被动补代码。
|
||||
|
||||
**之后**：加载 DSL → 0.1 秒内精确告知缺什么 → 补代码 → 注册能力 → 通过 → 模拟验证。
|
||||
|
||||
更重要的是：**能力清单本身成了引擎的文档**。任何开发者一看就知道引擎支持什么不支持什么，不需要翻代码。
|
||||
|
||||
#### 能力粒度设计
|
||||
|
||||
不是所有能力都需要显式声明。只声明**声明式 DSL 无法表达、需要代码实现的**：
|
||||
|
||||
| 声明式可表达的 | 不需要声明 (隐含在 DSL 声明本身) |
|
||||
|---|---|
|
||||
| `pattern.single`、`pattern.pair` | ✅ PatternMatcher 自动从 DSL 定义工作 |
|
||||
| `validator.must_be_larger` | ✅ ValidatorChain 从 DSL 规则链工作 |
|
||||
| `scoring.expression` | ✅ ScoreEngine 从 DSL formula 工作 |
|
||||
|
||||
| 需要引擎代码实现的 | 需要注册 Capability |
|
||||
|---|---|
|
||||
| `meldsolver.*` | 🔧 胡牌判断算法分支 |
|
||||
| `phase.mahjong_turn` | 🔧 复杂的麻将专有回合类型 |
|
||||
| `phase.parallel_elimination` | 🔧 血战淘汰逻辑 |
|
||||
| `deck.wildcard` | 🔧 百搭牌/鬼牌处理 |
|
||||
|
||||
规则：**DSL 本身能驱动的，不注册 Capability。需要引擎里写代码的，必须注册。**
|
||||

规则引擎是纯逻辑库，不调 LLM、不调外部服务。LLM 是可选的 DSL 生产工具，在规则引擎外部运行。
|
||||
|
||||
### 2.2 规则引擎如何实现 100% 覆盖
|
||||
|
||||
核心思想：**不预定义任何玩法。所有的"玩法"都是对一组原子能力的参数化配置。**
|
||||
|
||||
规则引擎暴露 5 个原子模块，每个模块的能力边界足够宽，宽到能覆盖所有棋牌玩法：
|
||||
|
||||
#### 模块 1: DeckManager — 牌的定义与分配
|
||||
|
||||
不预设"扑克52张"或"麻将108张"。牌是一个抽象数据结构：
|
||||
|
||||
```csharp
|
||||
// C# — int 编码
|
||||
// 万1-9=1-9, 条1-9=11-19, 筒1-9=21-29
|
||||
public static class MahjongTile
|
||||
{
|
||||
public static int Encode(string suit, int rank) => suit switch
|
||||
{
|
||||
"万" => rank, "条" => 10 + rank, "筒" => 20 + rank
|
||||
};
|
||||
public static string Decode(int tile) => tile switch
|
||||
{
|
||||
>= 1 and <= 9 => $"{tile}万",
|
||||
>= 11 and <= 19 => $"{tile - 10}条",
|
||||
>= 21 and <= 29 => $"{tile - 20}筒"
|
||||
};
|
||||
}
|
||||
```
|
||||
|
||||
DSL 定义牌的集合：
|
||||
|
||||
```yaml
|
||||
deck:
|
||||
# 52张标准扑克
|
||||
- generator: "standard_poker"
|
||||
jokers: 2 # 0=无王, 2=大小王
|
||||
|
||||
# 或自定义
|
||||
- generator: "custom"
|
||||
cards:
|
||||
- { suit: "万", ranks: [1,2,3,4,5,6,7,8,9], count: 4 }
|
||||
- { suit: "条", ranks: [1,2,3,4,5,6,7,8,9], count: 4 }
|
||||
- { suit: "筒", ranks: [1,2,3,4,5,6,7,8,9], count: 4 }
|
||||
- { suit: "字", ranks: [1,2,3,4,5,6,7], count: 4 } # 东南西北中发白
|
||||
- { suit: "花", ranks: [1,2,3,4,5,6,7,8], count: 1 } # 春夏秋冬梅兰竹菊
|
||||
```
|
||||
|
||||
发牌也是声明式：
|
||||
|
||||
```yaml
|
||||
deal:
|
||||
cards_per_player: 13 # 四川麻将每人13张(庄家14张)
|
||||
remaining_strategy: "pool" # 剩余牌做底牌池
|
||||
# 或者
|
||||
- to: "landlord"
|
||||
count: 3
|
||||
condition: "after_bid" # 叫地主后才发底牌
|
||||
```
|
||||
|
||||
#### 模块 2: PatternMatcher — 牌型匹配
|
||||
|
||||
不是硬编码"顺子是5张连续"，而是声明式定义：
|
||||
|
||||
```yaml
|
||||
patterns:
|
||||
single:
|
||||
match: { count: 1 }
|
||||
|
||||
pair:
|
||||
match: { count: 2, same_rank: true }
|
||||
|
||||
straight:
|
||||
match:
|
||||
count: { min: 5, max: 12 } # 长度范围
|
||||
consecutive_rank: true # 点数连续
|
||||
same_suit: false # 不要求同花色
|
||||
|
||||
flush_straight: # 同花顺
|
||||
match:
|
||||
count: { min: 5, max: 12 }
|
||||
consecutive_rank: true
|
||||
same_suit: true # 额外要求同花色
|
||||
|
||||
bomb_4: # 4张炸弹
|
||||
match: { count: 4, same_rank: true }
|
||||
|
||||
bomb_5: # 5张炸弹(掼蛋)
|
||||
match: { count: 5, same_rank: true }
|
||||
|
||||
bomb_rocket: # 火箭(大小王)
|
||||
match:
|
||||
cards: ["joker_small", "joker_big"]
|
||||
|
||||
full_house: # 三带二
|
||||
match:
|
||||
groups:
|
||||
- { count: 3, same_rank: true }
|
||||
- { count: 2, same_rank: true }
|
||||
|
||||
airplane: # 飞机带翅膀
|
||||
match:
|
||||
groups:
|
||||
- { count: 3, same_rank: true, consecutive: true, min_groups: 2 }
|
||||
- { count: 1, same_rank: false, per_group: true } # 每组三张带一个单牌
|
||||
```
|
||||
|
||||
牌型匹配器的实现是**通用模式匹配算法**，跟具体玩法无关。DSL 定义模式 → 匹配器识别手牌中所有满足的牌型组合。
|
||||
|
||||
#### 模块 3: ValidatorChain — 出牌校验
|
||||
|
||||
校验是**规则链**，每条规则是独立函数，DSL 声明链条：
|
||||
|
||||
```yaml
|
||||
play_validator:
|
||||
chain:
|
||||
- rule: "must_follow_pattern" # 必须跟牌型
|
||||
- rule: "must_be_larger" # 必须比上家大
|
||||
- rule: "bomb_anytime" # 炸弹可以任何时候出(打断规则链)
|
||||
except_when: "round_first" # 但首轮不能用炸弹(掼蛋规则)
|
||||
- rule: "comparator" # 自定义比较器
|
||||
type: "bomb_size_first" # 掼蛋：张数优先
|
||||
```
|
||||
|
||||
每条规则的实现是通用函数：
|
||||
|
||||
```csharp
|
||||
bool MustBeLarger(List<int> current, List<int> previous, GameContext ctx);
|
||||
bool MustFollowPattern(List<int> current, List<int> previous);
|
||||
bool BombAnytime(List<int> cards, GameContext ctx);
|
||||
```
|
||||
|
||||
**100%覆盖的关键：当声明式规则不够用时，`comparator` 字段可以指向一个沙盒函数：**
|
||||
|
||||
```yaml
|
||||
play_validator:
|
||||
chain:
|
||||
- rule: "comparator"
|
||||
custom: |
|
||||
// 掼蛋炸弹比较：张数优先，同张数比点数
|
||||
function compare(a, b) {
|
||||
if (a.length !== b.length) return a.length > b.length;
|
||||
return a[0].rank > b[0].rank;
|
||||
}
|
||||
```
|
||||
|
||||
沙盒函数提供了**图灵完备的兜底**，确保没有玩法无法表达。但 90% 的玩法不需要走到这步。
|
||||
|
||||
#### 模块 4: PhaseMachine — 回合流转
|
||||
|
||||
玩法流程本质是一个**有限状态机**：
|
||||
|
||||
```yaml
|
||||
phases:
|
||||
- name: "deal"
|
||||
type: "auto" # 自动执行，不需要玩家操作
|
||||
action: "deal_cards"
|
||||
next: "bid"
|
||||
|
||||
- name: "bid"
|
||||
type: "auction" # 竞价
|
||||
options: # 可选操作
|
||||
- action: "bid"
|
||||
value: [1, 2, 3] # 叫1/2/3分
|
||||
- action: "pass" # 不叫
|
||||
winner_rule: "highest_bid" # 价高者得
|
||||
next_on_winner: "set_landlord"
|
||||
next_on_all_pass: "deal" # 全部不叫重新发牌
|
||||
|
||||
- name: "play"
|
||||
type: "turn_based"
|
||||
turn_order: "clockwise"
|
||||
first_player: "landlord" # 地主先出
|
||||
actions:
|
||||
- action: "play_cards"
|
||||
validator: "play_validator"
|
||||
- action: "pass"
|
||||
end_condition: "one_player_empty" # 任一人打完手牌
|
||||
next: "settle"
|
||||
|
||||
- name: "settle"
|
||||
type: "auto"
|
||||
action: "calculate_scores"
|
||||
next: null # null = 游戏结束
|
||||
|
||||
# 麻将的特殊阶段
|
||||
- name: "draw_and_discard"
|
||||
type: "turn_based"
|
||||
actions:
|
||||
- action: "draw_card"
|
||||
- action: "discard"
|
||||
- action: "pung" # 碰（暂存，等优先级仲裁）
|
||||
priority: 2
|
||||
- action: "kong" # 杠
|
||||
priority: 3
|
||||
- action: "win" # 胡
|
||||
priority: 4
|
||||
priority_policy: "highest_wins" # 多人同时操作时，优先级高的生效
|
||||
|
||||
# 血战到底的特殊性：有人胡后不结束
|
||||
- name: "blood_war"
|
||||
type: "parallel_elimination" # 并行淘汰
|
||||
on_player_win: "remove_from_round" # 胡牌的人退出
|
||||
next_on_last_two: "settle" # 剩2人结束
|
||||
```
|
||||
|
||||
状态机引擎是通用的，DSL 只需要定义节点和转换条件。
|
||||
|
||||
#### 模块 5: ScoreEngine — 计分结算
|
||||
|
||||
三种模式，按复杂度递进：
|
||||
|
||||
```yaml
|
||||
scoring:
|
||||
# 模式1: 表达式 — 90% 的玩法
|
||||
mode: "expression"
|
||||
formula: "base * bombs * spring * landlord_factor"
|
||||
variables:
|
||||
base: 1
|
||||
bombs:
|
||||
source: "game_stats"
|
||||
key: "bomb_count"
|
||||
multiplier: 2 # 每个炸弹翻倍
|
||||
spring:
|
||||
source: "game_stats"
|
||||
key: "is_spring"
|
||||
multiplier: 2
|
||||
landlord_factor:
|
||||
source: "role"
|
||||
values: { landlord: 1, farmer: -1 } # 地主赢+1倍，农民赢每人-1倍
|
||||
|
||||
# 模式2: 查表 — 番型/牌型固定倍数
|
||||
mode: "table"
|
||||
table:
|
||||
- pattern: "flush_straight"
|
||||
base_multiplier: 4
|
||||
- pattern: "bomb_4"
|
||||
base_multiplier: 2
|
||||
- pattern: "bomb_5"
|
||||
base_multiplier: 4
|
||||
- pattern: "rocket"
|
||||
base_multiplier: 4
|
||||
stacking: "multiply" # 番型叠加方式：multiply | add | max
|
||||
|
||||
# 模式3: 自定义函数 — 极度复杂的计分
|
||||
mode: "custom"
|
||||
function: |
|
||||
// 四川麻将番型计算
|
||||
// 内置麻将算法库已提供 tilesToMelds() 分解牌型
|
||||
function calculate(tiles, melds, context) {
|
||||
let fans = [];
|
||||
if (melds.every(m => m.suit === melds[0].suit)) fans.push("清一色");
|
||||
if (melds.every(m => m.type === "pung")) fans.push("对对胡");
|
||||
// ... 内置算法库预处理好的数据，这里只做组合打分
|
||||
return fanTable.lookup(fans);
|
||||
}
|
||||
```
|
||||
|
||||
**关键设计**：custom 函数不自己处理"牌型分解"等复杂算法——那是内置算法库的事。custom 只做"基于预处理结果做决策"，大幅降低沙盒函数的复杂度和风险。
|
||||
|
||||
### 2.3 热切换机制
|
||||
|
||||
热切换的核心：**规则引擎是无状态的纯函数，每个房间持有自己的规则引用。**
|
||||
|
||||
```
|
||||
创建房间 API:
|
||||
POST /rooms
|
||||
{ ruleSetId: "doudizhu", playerCount: 3 }
|
||||
|
||||
服务端处理:
|
||||
1. rules = ruleRegistry.get("doudizhu") // 从内存缓存拿
|
||||
2. if (!rules) rules = ruleLoader.load("dsl-examples/doudizhu.yaml")
|
||||
3. room = new Room(rules, players)
|
||||
4. room.start()
|
||||
→ rules.deal() // 按 doudizhu 的 deal 配置发牌
|
||||
→ rules.phases.start() // 进入 bid phase
|
||||
→ 玩家操作 → rules.validator.chain.check()
|
||||
→ ...
|
||||
→ rules.scoring.calculate() // 结算
|
||||
```
|
||||
|
||||
规则加载流程：
|
||||
|
||||
```
|
||||
启动时:
|
||||
ruleRegistry.preload("dsl-examples/*.yaml")
|
||||
→ 每个 yaml 解析为 RuleObject
|
||||
→ Schema 校验（牌面定义完整性、phase 可达性检查）
|
||||
→ 缓存到内存
|
||||
|
||||
运行时:
|
||||
创建房间时 ruleId 命中缓存 → 直接使用
|
||||
新玩法上线: 只需把 yaml 放到 dsl-examples/ 目录
|
||||
→ 调用 ruleRegistry.reload("new_game")
|
||||
→ 已有的房间不受影响（持有旧 RuleObject 引用）
|
||||
→ 新房间使用新规则
|
||||
```
|
||||
|
||||
**规则隔离保证：**
|
||||
|
||||
- 每个 Room 实例持有自己的 `RuleObject` 引用（不可变对象）
|
||||
- 热加载新规则创建新的 RuleObject，旧引用不受影响
|
||||
- 已有房间继续用旧规则运行到结束
|
||||
- 新创建的房间自动使用最新版本规则
|
||||
|
||||
**多玩法并行：**
|
||||
|
||||
同一台服务器可以同时运行斗地主房间（100个）、炸金花房间（50个）、掼蛋房间（30个）——每个房间的规则引擎实例独立，互不干扰。唯一共享的是牌型匹配器等无状态工具函数。
|
||||
|
||||
### 2.3b 与游戏引擎的整合：不存在大的集成问题
|
||||
|
||||
规则引擎暴露的接口非常窄——就两个端点，纯 JSON 进、纯 JSON 出。如果是独立服务模式，接口为 HTTP；如果是 C# DLL 嵌入 Unity，接口为函数调用：
|
||||
|
||||
```
|
||||
// C# 嵌入模式（推荐）
|
||||
var room = new Room(rules, players);
|
||||
room.Start(); // → 自动发牌 → 进入 play phase
|
||||
var actions = room.GetLegalActions(playerId);
|
||||
room.Act(action); // → 规则引擎校验 → 更新状态 → 事件
|
||||
|
||||
// HTTP 独立服务模式（多语言场景备选）
|
||||
POST /rooms
|
||||
body: { ruleSetId: "doudizhu", engineType: "poker", players: ["p1","p2","p3"] }
|
||||
POST /rooms/:id/act
|
||||
body: { playerId: "p1", action: { type: "bid", value: 3 } }
|
||||
```
|
||||
|
||||
游戏引擎只需要做三件事，跟用什么引擎无关：
|
||||
|
||||
```
|
||||

|

│ 游戏引擎 (任意) │

||||
```
|
||||
|
||||
**集成成本分析：**
|
||||
|
||||
| 游戏引擎 | 适配方式 | 适配器代码量 | 说明 |
|
||||
|----------|---------|------------|------|
|
||||
| HTML5 Canvas | fetch + JSON.parse，渲染用 `ctx.drawImage()` | ~100 行 | 同语言，零成本 |
|
||||
| Cocos Creator (H5) | `cc.assetManager` 加载牌面纹理，`fetch` 调 API | ~200 行 | 同是 JS，直接调用 |
|
||||
| Cocos Creator (原生) | HTTP 请求 + 牌面纹理绑定 | ~200 行 | 原生 HTTP 略有差异 |
|
||||
| Unity (C#) | `UnityWebRequest` + JSON → C# class | ~250 行 | 需要 C# 版 Card 类型定义 |
|
||||
| 微信小游戏 | `wx.request` + Canvas 渲染 | ~150 行 | 不能直接用 fetch |
|
||||
|
||||
每个引擎写一个薄 adapter，本质就是：
|
||||
1. JSON → 对应的语言类型
|
||||
2. 调 HTTP
|
||||
3. 驱动渲染
|
||||
|
||||
规则引擎不关心前端用什么——state 和 action 都是纯 JSON。不存在"深度耦合"的空间。
|
||||
|
||||
**三种部署模式：**
|
||||
|
||||
| 模式 | 适用场景 | 延迟 |
|
||||
|------|---------|------|
|
||||
| 规则引擎独立服务器（推荐） | 多端共享逻辑，统一管理 | ~5ms 内网 |
|
||||
| WASM 嵌入客户端 | 单机/离线模式，无服务端 | 本地 0ms |
|
||||
| 规则引擎嵌入游戏服务器进程 | 小规模部署 | 函数调用 0ms |
|
||||
|
||||
推荐嵌入模式——规则引擎作为 C# DLL 直接编译进 Unity 进程，零 IPC 开销。AI 陪打独立 Python 服务。
|
||||
|
||||
### 2.3c Unity C# 集成方案：规则引擎用 C# 重写
|
||||
|
||||
如果确定 **Unity 是主要平台 + 规则引擎和游戏服务器同进程**，最干净的做法是规则引擎用 C# 写，直接编译进 Unity game server。不需要 Node.js。
|
||||
|
||||
**为什么 C#：** 规则引擎是纯逻辑——Card 结构体、PatternMatcher 算法、状态机流转、表达式计分。这些不依赖任何 TS 特有生态，C# 实现同样简洁。
|
||||
|
||||
**技术栈映射：**
|
||||
|
||||
| 能力 | TS 方案 | C# 方案 |
|
||||
|------|---------|---------|
|
||||
| YAML DSL 解析 | `js-yaml` | `YamlDotNet` (NuGet, 成熟) |
|
||||
| 表达式计分 | 手写 parser | `NCalc` 或手写，C# 表达式树 |
|
||||
| 牌型匹配 | 泛型 pattern match | LINQ + 自定义 matcher，逻辑完全一样 |
|
||||
| 校验链 | 函数链 | `Func<CardGroup,CardGroup,bool>` 链 |
|
||||
| 状态机 | 手写 | 手写，或 `Stateless` (NuGet) |
|
||||
| 沙盒 custom 函数 | Docker | `Microsoft.CodeAnalysis.CSharp.Scripting` — C# 脚本引擎，同语言原生沙盒 |
|
||||
|
||||
**关键优势：C# 原生沙盒远优于 Docker。**
|
||||
|
||||
Docker 方案的问题是——custom 计分/比较函数需要跨进程调用，序列化开销大，调试困难。C# 的 `Microsoft.CodeAnalysis.CSharp.Scripting` 可以在同进程内编译执行 C# 脚本，天然隔离（默认禁止 IO/网络），性能跟编译代码一样：
|
||||
|
||||
```csharp
|
||||
// DSL 中定义的 custom 比较函数，在 C# 原生沙盒执行
|
||||
var options = ScriptOptions.Default
|
||||
.WithReferences(typeof(Card).Assembly)
|
||||
.WithImports("System", "System.Linq");
|
||||
|
||||
// 掼蛋炸弹比较：张数优先
|
||||
var result = await CSharpScript.EvaluateAsync<bool>(
|
||||
@"cardsA.Length != cardsB.Length
|
||||
? cardsA.Length > cardsB.Length
|
||||
: cardsA[0].Rank > cardsB[0].Rank",
|
||||
options,
|
||||
globals: new { cardsA, cardsB });
|
||||
```
|
||||
|
||||

|

**AI 和规则引擎的边界：**
|
||||
|
||||
| | 规则引擎 (C#) | AI 陪打 (Python) |
|
||||
|---|---|---|
|
||||
| 职责 | "能不能出这张牌" | "出哪张牌最好" |
|
||||
| 输入 | PlayerAction | GameState + legalActions |
|
||||
| 输出 | NewGameState + events | 选中的 PlayerAction |
|
||||
| 确定性 | 100% 确定 | 概率性 |
|
||||
| 依赖 | DSL yaml、自身算法 | MCTS 库、LLM SDK、NumPy |
|
||||
|
||||
分离的理由：规则引擎是确定性逻辑（可以单元测试覆盖到 100%），AI 是概率性策略（需要迭代优化）。两者不应该混在一个进程里。

|
||||
|
||||
**为什么不两者都用 Python？** 规则引擎需要跑在 Unity 进程里（C# 环境），同语言零开销。如果规则引擎也用 Python，那就又回到独立服务 + HTTP 调用的模式——对纯 Unity 部署来说多了一层不必要的 IPC。
|
||||
|
||||
**总结：规则引擎 C# 实现 → 编译为 DLL → Unity 直接引用。AI 陪打独立 Python 服务。DSL yaml 文件语言无关，两边都能读。**
|
||||
|
||||
### 2.3d AI 陪打架构：规则引擎判定合法性，AI 决策最优策略
|
||||
|
||||
#### 核心概念
|
||||
|
||||
规则引擎和 AI 陪打是两个独立的系统，通过极窄的接口通信：
|
||||
|
||||
```
|
||||
规则引擎 (C#) ──┤我能出哪些牌？│──→ AI 陪打 (Python)
|
||||
↑ 执行决策 ←──│我选这个操作 │── ↓ 策略计算
|
||||
```
|
||||
|
||||
- **规则引擎**回答"能/不能"：出牌是否合法、碰杠胡是否符合规则、结算是否正确。每步判断 100% 确定，可以 100% 测试覆盖。
|
||||
- **AI 陪打**回答"好/不好"：在手牌 A/B/C 中选哪个胜率最高。概率性决策，不需要 100% 正确，只要比随机好。
|
||||
|
||||
分离的理由：规则引擎是确定性逻辑——单元测试可以精确验证每条规则。AI 是概率性策略——需要 MCTS 搜索库、LLM SDK、NumPy 等 Python 生态。两者混在一个进程里调试会互相污染。
|
||||
|
||||
#### 接口定义
|
||||
|
||||
**AI 服务暴露一个端点：**
|
||||
|
||||
```
|
||||
POST /ai/decide
|
||||
请求:
|
||||
{
|
||||
"player_hand": [1, 1, 1, 2, 3, 4, ...], // 手牌 (int 编码)
|
||||
"exposed": [...], // 已碰/杠的牌
|
||||
"discard_pool": [28, 15, 3, ...], // 弃牌堆
|
||||
"last_discard": 22, // 刚打出的牌
|
||||
"legal_actions": [ // 规则引擎已算好的合法操作
|
||||
{ "type": "discard", "tile": 1 },
|
||||
{ "type": "discard", "tile": 3 },
|
||||
{ "type": "pung", "tiles": [22, 22, 22] },
|
||||
{ "type": "win", "fan_count": 6 }
|
||||
],
|
||||
"game_context": { // 游戏上下文
|
||||
"round": 5,
|
||||
"remaining_tiles": 40,
|
||||
"scores": { "AI-东": 12, "AI-南": -4 }
|
||||
}
|
||||
}
|
||||
|
||||
响应:
|
||||
{
|
||||
"chosen_action": { "type": "win", "fan_count": 6 },
|
||||
"confidence": 0.95, // 决策置信度
|
||||
"thinking_time_ms": 42 // 决策耗时
|
||||
}
|
||||
```
|
||||
|
||||
**C# 端调用流程：**
|
||||
|
||||
```csharp
|
||||
// 在 Unity Game Server 的每回合中：
|
||||
if (currentPlayer.IsAI) {
|
||||
// 1. 规则引擎算好所有合法操作
|
||||
var legalActions = engine.GetLegalActions(state, playerId);
|
||||
|
||||
// 2. 调 AI 服务
|
||||
var request = BuildAiRequest(state, playerId, legalActions);
|
||||
var response = await _aiClient.DecideAsync(request);
|
||||
|
||||
// 3. AI 选中的操作就是玩家操作
|
||||
engine.ExecuteAction(state, response.ChosenAction);
|
||||
}
|
||||
```
|
||||
|
||||
这个接口设计的要点：**AI 不需要自己判断合法性——规则引擎已经把合法操作列表算好了。** AI 只做"选择题"：在 N 个合法操作中选最好的。如果 AI 服务挂了或超时，降级为随机选一个合法操作（`legal_actions[random]`），游戏不中断。
|
||||
|
||||
#### 三级 AI 难度
|
||||
|
||||
| 级别 | 策略 | 运行位置 | 延迟 | 强度 |
|
||||
|------|------|---------|------|------|
|
||||
| **难度 1** | 规则合法随机 | C# 进程内 | < 0.1ms | 弱 |
|
||||
| **难度 2** | MCTS + 启发式评估 | Python 独立服务 | ~50ms | 中 |
|
||||
| **难度 3** | LLM Agent (ReAct) | Python + LLM API | ~2s | 强 |
|
||||
|
||||
**难度 1 — 规则合法随机（Demo 阶段实现）**
|
||||
|
||||
```csharp
|
||||
public class RandomMahjongAI {
|
||||
public PlayerAction Decide(MahjongGameState state, List<PlayerAction> legalActions) {
|
||||
// 启发式过滤：能胡就胡、能杠就杠、否则随机
|
||||
var hu = legalActions.FirstOrDefault(a => a.Type == "win");
|
||||
if (hu != null) return hu;
|
||||
|
||||
var kong = legalActions.FirstOrDefault(a => a.Type is "an_kong" or "ming_kong");
|
||||
if (kong != null && Random.Shared.Next(4) > 0) return kong;
|
||||
|
||||
var discards = legalActions.Where(a => a.Type == "discard").ToList();
|
||||
return discards[Random.Shared.Next(discards.Count)];
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
不打外部服务，直接跑在 C# 进程里。Demo 阶段用这个就够验证规则引擎正确性。
|
||||
|
||||
**难度 2 — MCTS 启发式搜索（后实现）**
|
||||
|
||||
```
|
||||
Python 服务启动时加载麻将规则（通过 YAML DSL 了解番型和计分）
|
||||
↓
|
||||
收到决策请求 → 以当前状态为根节点
|
||||
↓
|
||||
MCTS 搜索树：
|
||||
1. Selection: 从根节点选最有潜力的分支 (UCB1)
|
||||
2. Expansion: 展开一个未探索的操作
|
||||
3. Simulation: 随机模拟到终局（双方都用随机策略）
|
||||
4. Backpropagation: 回传胜负结果更新节点统计
|
||||
↓
|
||||
搜索 200ms → 返回访问次数最多的操作
|
||||
```
|
||||
|
||||
MCTS 的核心优势：不需要手写评估函数。只要能从"终局结果"回传胜负信号，它自己学会哪些手牌好、哪些操作差。
|
||||
|
||||
对于麻将，评估函数可以辅助加速：
|
||||
- 听牌距离（离胡牌差几张）
|
||||
- 番型潜力（手牌中已有多少番型的"零件"）
|
||||
- 安全度（打这张牌别人胡的概率）
|
||||
|
||||
**难度 3 — LLM Agent（远期目标）**
|
||||
|
||||
```python
|
||||
def decide_with_llm(state, legal_actions):
|
||||
prompt = f"""
|
||||
你是麻将高手。当前手牌：{render_hand(state.hand)}
|
||||
桌面已出：{render_pool(state.discard_pool)}
|
||||
可选项：{render_actions(legal_actions)}
|
||||
请选择最优操作并解释原因。
|
||||
"""
|
||||
response = llm.chat(prompt, response_format="json")
|
||||
return parse_action(response)
|
||||
```
|
||||
|
||||
只在关键回合调 LLM（听牌/防守/大番型决策），其余用 MCTS 降级。成本控制：每局限 3-5 次 LLM 调用。
|
||||
|
||||
#### 部署架构

|

|

- 开发环境：Python 和 C# 都跑在 localhost，延迟 ~1ms
|
||||
- 生产环境：AI 服务可以独立部署到 GPU 服务器，C# 游戏服务器通过内网 HTTP 调用
|
||||
- 容灾：AI 超时 → 降级为难度 1（随机合法），玩家无感知
|
||||
|

#### Demo 阶段做哪些
|

|

| | Demo 实现 | 后续实现 |
|

### 2.4 Rule DSL 完整结构
|
||||
|
||||
声明式优于命令式。核心实体：
|
||||
|
||||
```yaml
|
||||
game:
|
||||
type: "poker" | "mahjong" | "board"
|
||||
players: {min: 2, max: 6}
|
||||
|
||||
deck:
|
||||
cards: "standard_52" | "standard_54" | custom
|
||||
custom_cards: [...] # 自定义牌面

- name: "对子"
|
||||
match: {type: "pair"}
|
||||
- name: "顺子"
|
||||
match: {type: "straight", min_length: 5, max_length: 12}
|
||||
|
||||
validators: # 出牌校验逻辑
|
||||
- name: "card_pattern_validator"
|
||||
rules:
|
||||
- "must_follow_pattern" # 跟牌型
|
||||
- "must_be_larger" # 必须更大
|
||||
- "bomb_overrides" # 炸弹可压任何牌
|
||||
|
||||
scoring:
|
||||
type: "expression" | "table" | "custom"
|
||||
# expression: "base_score * multiplier"
|
||||
# table: 查表
|
||||
# custom: 用户提供的评分函数（沙盒执行）
|
||||
```
|
||||
|
||||
这个 DSL 的设计原则：**90% 的玩法用声明式覆盖，10% 的特殊规则走 custom + 沙盒。**
|
||||
|
||||
---
|
||||
|
||||
## 三、MVP Demo 落地路径
|
||||
|
||||
以上是完整架构。但先不用全做——用最小闭环验证核心链路。
|
||||
|
||||
### Phase 0: 控制台麻将 Demo (预计 6-8 天)
|
||||
|
||||
> **详细计划已独立为文档**: 见 `docs/demo-implementation-plan.md`
|
||||
|
||||
**目标:** C# 控制台程序，4 个随机 AI 自动打完四川麻将血战到底 + 广东鸡平胡。验证 MeldsSolver（回溯搜索胡牌判断）+ 番型互斥图 + 血战淘汰 + DSL 热切换。
|
||||
|
||||
关键模块：
|
||||
|
||||
```
|
||||
MeldsSolver — 回溯搜索胡牌判断（核心算法）
|
||||
Deck — 108张牌堆管理
|
||||
PhaseMachine — 摸牌→出牌→碰杠胡优先级仲裁→血战淘汰→查叫查花猪
|
||||
ScoreEngine — 番型表计分 + 互斥图 + 结算前钩子
|
||||
DslLoader — YamlDotNet 加载 + 能力检查
|
||||
RandomAI — 规则合法随机（能胡就胡、能杠就杠、否则随机出）
|
||||
```
|
||||
|
||||
完成标准：78 个测试全绿、1000 局零报错、换 DSL 不需要重新编译。
|
||||
|
||||
**Phase 0 之后的路线：**
|
||||
|
||||
```
|
||||
Phase 0 ✅ 控制台麻将 Demo (本阶段)
|
||||
↓
|
||||
麻将引擎扩展: wildcard、全不靠、一色双龙会（补 3 个算法分支）
|
||||
↓
|
||||
Unity 前端: 麻将牌面渲染 + 出牌操作 UI
|
||||
↓
|
||||
Python AI 服务: MCTS + LLM Agent
|
||||
↓
|
||||
10+ 麻将玩法 DSL + CI 压测
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 四、完整实施路线图 (Phase 0 之后)
|
||||
|
||||
### Phase 1: 调研与选型 (预计 2-3 天)
|
||||
|
||||
**目标:** 确定技术选型，产出选型报告
|
||||
|
||||
#### Task 1.1: 游戏前端渲染层选型
|
||||
|
||||
规则引擎独立于渲染层，这里只选前端展示方案：
|
||||
|
||||
| 方案 | 优势 | 劣势 | 适合 |
|
||||
|------|------|------|------|
|
||||
| 纯 HTML5 Canvas + JS | 零依赖，WebSocket 直连 | 动画需要手写 | 原型/MVP |
|
||||
| Cocos Creator | 棋牌生态成熟，组件丰富 | 绑定 Cocos 生态，包体大 | 正式产品 |
|
||||
| Phaser 3 | 轻量 2D 框架 | 无棋牌生态 | H5 小游戏 |
|
||||
|
||||
**结论倾向**: MVP 阶段用纯 Canvas 原型，验证规则引擎后再决定是否切 Cocos。规则引擎不依赖任何前端框架。
|
||||
|
||||
#### Task 1.2: 规则引擎核心能力定义与覆盖分析
|
||||
|
||||
明确规则引擎必须处理的 4 类核心逻辑：
|
||||
|
||||
1. **牌型匹配**: 单张/对子/顺子/炸弹/... — 声明式 pattern match
|
||||
2. **出牌校验**: 跟牌型/必须更大/特殊牌型覆盖 — 声明式 validator 链
|
||||
3. **回合流转**: 叫地主/出牌/跟注/开牌 — 声明式 phase 状态机
|
||||
4. **计分结算**: 底分×倍数+特殊牌型加成 — expression/table/custom
|
||||
|
||||
**覆盖分析 — 枚举 6 种代表性玩法实测边界：**
|
||||
|
||||
| 玩法 | 牌型匹配 | 出牌校验 | 回合流转 | 计分结算 | 4类覆盖率 | 缺口 |
|
||||
|------|---------|---------|---------|---------|----------|------|
|
||||
| 炸金花 | ✓ 6种牌型 | ✓ 简单比大小 | ✓ 下注/跟/加/开/弃 | ✓ 底注+各轮 | **100%** | 无，诈唬是AI层的事 |
|
||||
| 牛牛 | ✓ 无牛/牛几/特殊牌型 | ✓ 纯比牌 | ✓ 下注→发牌→摊牌 | ✓ 牛几×倍数 | **100%** | 无 |
|
||||
| 斗地主 | ✓ 10+种牌型 | ✓ 跟牌型+大于+炸弹覆盖 | ✓ 发牌→叫地主→出牌→结算 | ✓ 底分×炸弹/春天倍数 | **100%** | 无 |
|
||||
| 跑得快 | ✓ 同斗地主 | ✓ 同斗地主 | ✓ 简化(无叫地主) | ✓ 剩牌计分 | **100%** | 无 |
|
||||
| 掼蛋 | ✓ 8+种+特殊炸弹规则 | ✓ 跟牌型+大于 | ✓ 进贡/还贡→出牌→升级 | ✓ 头游二游+级数 | **95%** | 炸弹比较逻辑特殊(张数优先>点数)，需自定义比较器 |
|
||||
| 四川麻将血战 | ✓ 顺/刻/杠/对子组合成14张 | ✓ 摸→出→碰/杠/胡优先级 | ✓ 血战到底+查叫 | ✓ 番型叠加计算 | **80%** | ①碰杠胡多人冲突需priority resolver ②胡牌判断是算法级(非声明式) ③番型组合爆炸需规则引擎预处理 |
|
||||
|
||||
**结论: 扑克类 95%+ 覆盖，麻将类 80% 覆盖但需要 3 个扩展点——**
|
||||
|
||||
| 扩展点 | 解决方案 | 优先级 |
|
||||
|--------|---------|--------|
|
||||
| 自定义比较器 | DSL 支持 `comparator: custom`，走沙盒函数 | 高（掼蛋炸弹等） |
|
||||
| 多人优先级仲裁 | 新增 `priority_resolver` 机制，规则配置优先级链 | 高（麻将碰杠胡） |
|
||||
| 复杂牌型算法 | 内置通用的"麻将胡牌判断""十三水分牌""掼蛋炸弹比较"等算法库，DSL 引用 | 中（内置算法而非 LLM 生成） |
|
||||
|
||||
**关于问题 2:** 是的，一个规则引擎加载不同的 DSL YAML 文件就能动态切换玩法。核心设计就是"玩法即配置"——每个 `.yaml` 是一个玩法，引擎启动时加载，状态机自动按 phase 编排运行。换玩法 = 加载另一个 yaml，不需要重新编译、不需要重启服务。
|
||||
|
||||
**已验证的可覆盖玩法清单**（至少 20+）: 斗地主、炸金花、牛牛、跑得快、掼蛋、十三水、升级/拖拉机、桥牌、德州扑克、21点、梭哈、干瞪眼、五十K、红十、拱猪、大老二、UNO、斗牛、三公、百家乐。
|
||||
|
||||
#### Task 1.3: 现有棋牌 DSL/框架调研
|
||||
|
||||
- 搜索开源棋牌框架（如 cocos-creator 棋牌框架、nodejs 棋牌服务端）
|
||||
- 研究已有的棋牌规则描述方案
|
||||
- 调研类似 "rule engine as a service" 的项目
|
||||
|
||||
#### Task 1.4: LLM 规则提取能力验证
|
||||
|
||||
使用 3-5 种不同复杂度玩法做 Prompt 测试：
|
||||
1. 简单的：炸金花（牌型+比大小）
|
||||
2. 中等的：斗地主（叫地主+牌型+炸弹）
|
||||
3. 复杂的：四川麻将（血战+番型+计分）
|
||||
|
||||
**验证指标:**
|
||||
- 结构化提取的准确率
|
||||
- 遗漏规则的比例
|
||||
- 错误规则的比例
|
||||
|
||||
#### Task 1.5: 安全方案调研
|
||||
|
||||
- Docker 沙盒执行自定义计分函数的可行性
|
||||
- WebAssembly 沙盒作为备选
|
||||
- 输入输出 schema 约束
|
||||
|
||||
### Phase 2: DSL 设计与验证 (预计 3-5 天)
|
||||
|
||||
**目标:** 设计并冻结 V1 版本的 Rule DSL，通过 3 种玩法验证
|
||||
|
||||
#### Task 2.1: DSL Schema 设计
|
||||
|
||||
```python
|
||||
# 用 Pydantic 定义 DSL Schema，自动获得校验
|
||||
class GameRule(BaseModel):
|
||||
type: Literal["poker", "mahjong", "board"]
|
||||
players: PlayerConfig
|
||||
deck: DeckConfig
|
||||
phases: list[Phase]
|
||||
patterns: list[CardPattern]
|
||||
validators: list[Validator]
|
||||
scoring: ScoringConfig
|
||||
```
|
||||
|
||||
#### Task 2.2: LLM Prompt 工程
|
||||
|
||||
设计 few-shot prompt，使 LLM 能从自然语言规则描述 → 生成 DSL JSON。
|
||||
|
||||
```
|
||||
System: 你是一个棋牌规则分析专家...
|
||||
User: 以下是"跑得快"的玩法描述：{description}
|
||||
请生成 DSL 规则配置。
|
||||
```
|
||||
|
||||
#### Task 2.3: 3 种玩法验证
|
||||
|
||||
- 炸金花 -> DSL -> 沙盒模拟 1000 局 -> 人工检查
|
||||
- 斗地主 -> DSL -> 沙盒模拟 1000 局 -> 人工检查
|
||||
- 简化麻将 -> DSL -> 沙盒模拟 1000 局 -> 人工检查
|
||||
|
||||
#### Task 2.4: DSL 版本管理
|
||||
|
||||
- git 管理每个玩法的 DSL 文件
|
||||
- 人工审核后打 tag 发版
|
||||
- 引擎按版本加载规则
|
||||
|
||||
### Phase 3: 游戏引擎集成 MVP (预计 5-7 天)
|
||||
|
||||
**目标:** 选 2 种玩法，完成从 DSL 到可玩游戏的完整链路
|
||||
|
||||
#### Task 3.1: 通用引擎核心
|
||||
|
||||
构建最小棋牌引擎核心（C#）：
|
||||
|
||||

|
||||
- 牌面渲染（扑克牌面、麻将牌面）
|
||||
- 操作按钮（出牌/跟注/弃牌/开牌）
|
||||
|
||||
### Phase 4: 陪打 AI 系统 (预计 5-7 天)
|
||||
|
||||
**目标:** 实现 3 级难度的陪打机器人
|
||||
|
||||
#### Task 4.1: 难度 1 — 规则合法随机
|
||||
|
||||
```python
|
||||
class RuleBasedAI:
|
||||
def decide(self, state, legal_moves):
|
||||
# 排除明显愚蠢的操作
|
||||
# 其余随机
|
||||
return random.choice(filtered_moves)
|
||||
```
|
||||
|
||||
#### Task 4.2: 难度 2 — 启发式 + MCTS
|
||||
|
||||
```
|
||||
- 基于 DSL scoring 规则构建评估函数
|
||||
- MCTS 搜索有限深度
|
||||

|
||||
```
|
||||
|
||||
#### Task 4.3: 难度 3 — LLM Agent
|
||||
|
||||
```
|
||||
- 输入：当前手牌 + 历史出牌 + 规则描述
|
||||
- 输出：出牌决策
|
||||
- 使用结构化输出确保合法性
|
||||
- 成本控制：仅在关键回合调用 LLM
|
||||
```
|
||||
|
||||
#### Task 4.4: AI 策略热切换
|
||||
|
||||
- 游戏中可按座位配置不同难度 AI
|
||||
- AI 接口统一，策略可插拔
|
||||
|
||||
### Phase 5: 安全沙盒 (预计 2-3 天)
|
||||
|
||||
**目标:** 安全执行用户自定义规则
|
||||
|
||||
#### Task 5.1: CSharpScript 沙盒
|
||||
|
||||
```csharp
|
||||
// 自定义计分/比较函数在 CSharpScript 沙盒中执行
|
||||
var options = ScriptOptions.Default
|
||||
.WithReferences(typeof(Card).Assembly)
|
||||
.WithImports("System", "System.Linq");
|
||||
var result = await CSharpScript.EvaluateAsync<bool>(customCode, options, globals);
|
||||
```
|
||||
|
||||
#### Task 5.2: 安全限制
|
||||
|
||||
- 默认禁止 IO/网络/反射
|
||||
- 输入输出 Schema 校验
|
||||
- 超时控制
|
||||
- 异常捕获降级为默认行为
|
||||
|
||||
### Phase 6: 扩展验证 (预计 3-5 天)
|
||||
|
||||
**目标:** 增加 5+ 玩法验证系统通用性
|
||||
|
||||
#### Task 6.1: 新玩法上线流程优化
|
||||
|
||||
目标：从拿到规则描述到可玩，30 分钟。
|
||||
|
||||
```
|
||||
1. 输入规则描述（口语化中文）
|
||||
2. LLM 生成 DSL (30s)
|
||||
3. 自动沙盒模拟 1000 局 (1min)
|
||||
4. 人工 review + 修正 (20min)
|
||||

|
||||
|
||||
## 五、关键风险与对策
|
||||
|
||||
| 风险 | 概率 | 影响 | 对策 |
|
||||
|------|------|------|------|
|
||||
| LLM 对复杂规则理解不准 | 高 | 中 | 分步提取 + 人工审核 + 模拟验证 |
|
||||
| DSL 表达能力不足 | 中 | 高 | custom 兜底函数，逐步扩展 DSL |
|
||||
| 引擎性能不够 | 低 | 中 | C# 足够，必要时热路径可换 Rust |
|
||||
| LLM 决策延迟高 | 中 | 中 | 混合策略：非关键回合不调 LLM |
|
||||
| 沙盒逃逸风险 | 低 | 极高 | 多层防御：Docker + seccomp + 只读FS |
|
||||
|
||||

|
||||
|
||||
## 六、项目目录结构规划
|
||||
|
||||
```
|
||||

|
||||
## 七、验证清单
|
||||
|
||||
- [ ] Phase 1: 选型报告完成
|
||||
- [ ] Phase 2: DSL 通过 3 种玩法验证
|
||||
- [ ] Phase 3: 2 种玩法可完整游玩
|
||||
- [ ] Phase 4: 3 级 AI 均能正确出牌
|
||||
- [ ] Phase 5: 沙盒通过安全审计
|
||||
- [ ] Phase 6: 5+ 玩法稳定运行
|
||||
|
||||
---
|
||||
|
||||
## 八、开放问题
|
||||
|
||||
1. **前端渲染层选型**: MVP 用纯 Canvas，后期是否切 Cocos Creator？取决于产品化需求，不影响规则引擎。
|
||||
2. **规则引擎语言**: C#（嵌入 Unity），确定。
|
||||
3. **DSL 表达力边界**: 是否需要图灵完备的 custom 函数？还是纯声明式足够？
|
||||
4. **LLM 成本**: 每次玩法生成调用 LLM 的成本是否可接受？（估计每次 < ¥0.5）
|
||||
5. **前端方案**: Cocos Creator 原生客户端还是 H5 小游戏？
|
||||
6. **商业模式**: 服务棋牌运营商还是自己做平台？

## 零、开源项目参考
|
||||
|
||||
开发前先了解已有轮子，避免重复造车。以下是搜到的关键项目：
|
||||
|
||||
### 0.1 yuanfengyun/q_algorithm ⭐2090 — C# 胡牌算法库
|
||||
|
||||
**地址**: https://github.com/yuanfengyun/q_algorithm
|
||||
|
||||
棋牌算法库，含麻将、跑胡子、扑克。**有 C# 版本**（`mjlib_c#` 目录），MIT 协议。核心特色：
|
||||
|
||||
- **查表法做胡牌判断**：预计算所有可能的胡牌组合存表，查询 O(1)。跟我们计划的回溯搜索法是两条路。
|
||||
- 多语言实现对比：lua/c++/c#/golang/js/java/python 各一套，可以对比理解算法精髓
|
||||
- 含跑胡子（一种地方牌类），说明算法设计有一定通用性
|
||||
|
||||
**我们可以借鉴**：
|
||||
- 胡牌算法对比：查表法 vs 回溯法选最优（查表快但维护表麻烦，回溯代码简单但最坏 O(3^n)）
|
||||
- C# 版代码风格：直接研究 `mjlib_c#` 目录，看他们怎么处理牌面编码、面子分解
|
||||
- 听牌算法：查表法的听牌判断思路
|
||||
- 测试数据：已有的胡牌/不胡牌的测试用例
|
||||
|
||||
**需要注意**：这个库只做胡牌判断，没有规则引擎、没有 DSL、没有计分。跟我们不是竞品，是底盘——可以嵌入我们的 MeldsSolver。
|
||||
|
||||
### 0.2 esrrhs/majiang_algorithm ⭐478 — Java 麻将算法 + AI
|
||||
|
||||
**地址**: https://github.com/esrrhs/majiang_algorithm
|
||||
|
||||
完整麻将引擎，Java 实现，含胡牌算法和 AI。MIT 协议。关键文件：
|
||||
|
||||
| 文件 | 内容 |
|
||||
|------|------|
|
||||
| `hu.md` | 详细的胡牌算法设计文档（必读！） |
|
||||
| `ai.md` | AI 算法思路：评估函数 + 搜索树 |
|
||||
| `majiang.db` | 预计算的牌型数据表 |
|
||||
| `majiang_ai_feng.txt` | AI 策略配置样例 |
|
||||
|
||||
**我们可以借鉴**：
|
||||
- `hu.md` 的算法设计思路——理解各种胡牌判断的坑（七对、十三幺、全不靠）
|
||||
- `ai.md` 的评估函数框架——手牌效率、安全度、进攻/防守系数（跟我们 Phase 3 的 Python AI 服务对接）
|
||||
- 番型表设计：如何组织番型数据、如何做番型叠加
|
||||
|
||||
### 0.3 MahjongKit ⭐53 — Python 牌谱分析工具包
|
||||
|
||||
**地址**: https://github.com/erreurt/MahjongKit
|
||||
|
||||
麻将工具包，Python 实现。含日志爬虫、数据预处理、确定性算法。用的是日本麻将（MajSoul/天凤）的牌谱数据。
|
||||
|
||||
**我们可以借鉴**：
|
||||
- 牌谱数据分析思路——后续做回归测试时，用真实牌谱验证引擎正确性
|
||||
- 番种计算的分治策略——如何把"81番种互斥"拆成可管理的子问题
|
||||
|
||||
### 0.4 MahjongPantheon/riichi-ts ⭐12 — TypeScript 番种计算
|
||||
|
||||
**地址**: https://github.com/MahjongPantheon/riichi-ts
|
||||
|
||||
专注番种（役种）计算，TypeScript 实现。算番逻辑独立模块。
|
||||
|
||||
**我们可以借鉴**：
|
||||
- 番种 `excludes`/`conflicts` 的实际代码实现——跟我们的 DSL 互斥图设计对应
|
||||
- TypeScript 代码可读性好，逻辑比 C# 版更容易快速理解
|
||||
|
||||
### 0.5 关键发现：没有现成的 DSL 驱动引擎
|
||||
|
||||
以上四个项目各有侧重——胡牌算法、AI、牌谱分析、番种计算。但**没有一个项目做到了"玩法即配置"**。它们都是"一种玩法一种代码"——想支持广东麻将就得手写一个广东麻将模块。所以我们这个 YAML DSL + 能力检查 + 热切换的方向是创新的。
|
||||
|
||||
**借鉴清单总结**：
|
||||

## 二-B、DSL 文件 — 广东麻将鸡平胡 (1 小时)
|
||||
|
||||
第二个 Demo 玩法。选广东麻将是因为它和四川血战在以下维度完全互补：
|
||||
|
||||
| 维度 | 四川血战到底 | 广东鸡平胡 |
|
||||
|------|------------|-----------|
|
||||
| 牌库 | 108张（无字无花） | 136张（+ 28张字牌） |
|
||||
| 花牌 | ❌ 无 | ✅ 8张花牌，摸到即补 |
|
||||
| 吃牌 | ❌ 不能吃 | ✅ 可以吃 |
|
||||
| 胡牌条件 | 缺一门 | 无限制，但有番型分级 |
|
||||
| 结束条件 | 血战淘汰 | 有人胡就结束 |
|
||||
| 番型体系 | ~10种，线性叠加 | ~30种，分三级（鸡/平/爆） |
|
||||
| 番型分级 | 无 | 鸡胡（最低）、平胡（中等）、爆胡（8番+） |
|
||||
| 鬼牌 | 无 | 可选（Demo 阶段先不做） |
|
||||
| 多人胡 | 优先级仲裁 | 一炮三响（全胡） |
|
||||
| 花牌计分 | N/A | 每花1番、正花额外 |
|
||||
| 连庄 | 无 | 有（胡牌者连庄） |
|
||||
|
||||

### 引擎验证点
|
||||
|
||||
武汉麻将 DSL 加载时，CapabilityRegistry 检查 `meldsolver.wildcard` ——如果未注册直接报错。**这迫使我们在 Demo 阶段就实现 wildcard 算法。**
|
||||
|
||||
```
|
||||
$ dotnet run -- --dsl wuhan
|
||||
|
||||
❌ DSL '武汉麻将' 需要: meldsolver.wildcard（宝牌/癞子支持）
|
||||
引擎尚未实现！
|
||||
请在 MeldsSolver.cs 中实现缺口填充式回溯后注册此能力。
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 三、RuleEngine 核心类 (3 天，含引擎扩展)
|
||||
|
||||
麻将引擎比扑克复杂——核心不是 PatternMatcher，而是 MeldsSolver（胡牌判断）。按这个顺序写，每个写完跑测试。
|
||||
|
||||
### 3.1 数据结构 (30 min)
|
||||
|
||||
#### MahjongTile.cs (60 行) — int 编码 + 静态工具类
|
||||
|
||||
不使用 struct 对象，直接用 `int` 编码。游戏引擎底层，性能优先。
|
||||
|
||||
编码规则：万1-9 = 1-9，条1-9 = 11-19，筒1-9 = 21-29。19 = 九条，28 = 八筒。
|
||||
|
||||
```csharp
|
||||
namespace RuleEngine.Core;
|
||||
|
||||
/// 麻将牌 int 编码工具类
|
||||
public static class MahjongTile
|
||||

### 3.3 MeldsSolver.cs — 核心！(4-6 小时, ~400 行)
|
||||
|
||||
这是整个麻将引擎最难的部分。胡牌判断 = 回溯搜索。
|
||||
|
||||
#### 3.3.0 胡牌算法选型：回溯 vs 查表
|
||||
|
||||
在开始写代码前，先决定用哪种算法（参考 q_algorithm 的查表法）。
|
||||
|
||||
| | 回溯搜索（我们计划） | 查表法（q_algorithm 采用） |
|
||||
|---|---|---|
|
||||
| 原理 | 14张牌递归拆解，先试刻子再试顺子 | 预计算所有胡牌组合存哈希表，O(1)查询 |
|
||||
| 时间复杂度 | 最坏 O(3^n)，n=14 时约 1000 次递归 | O(1) 查询 + O(n) 哈希 |
|
||||
| 代码量 | ~100行核心逻辑 | ~80行查询 + 需要预计算工具（额外200行） |
|
||||
| 扩展性 | 加新胡牌条件（全不靠/一色双龙会）只需加分支 | 需要重建表 |
|
||||
| 调试难度 | 容易单步跟踪 | 表数据出错难定位 |
|
||||
| 14张牌性能 | < 0.5ms（实测足够） | < 0.01ms |
|
||||
| 听牌判断 | O(牌种数) × O(回溯) ≈ 34×0.5ms = 17ms | O(牌种数) × O(1) = 0.3ms |
|
||||
|
||||
**选型结论：先做回溯搜索，后续如果听牌判断成为瓶颈再换查表法。** 理由：
|
||||
- Demo 阶段 4 人 AI 自动对打，听牌判断每回合调用 4 次 × 34 张可能牌 = 136 次回溯，17ms 完全不构成瓶颈
|
||||
- 回溯代码可读性强，容易加"全不靠""组合龙"等特殊分支
|
||||
- 等价于查表法的"验证"——如果回溯出 bug，查表法也会出错
|
||||
|
||||
#### 3.3.1 牌面编码方案
|
||||
|
||||
麻将牌在 C# 中的编码方式直接影响算法效率。两种方案：
|
||||
|
||||
| | 对象法 | 整数编码法 |
|
||||
|---|---|---|
|
||||
| 表示 | `new MahjongTile("万", 5)` | `int tile = 5`（万5=5, 条5=15, 筒5=25） |
|
||||
| 排序 | 按 Suit+Rank，~10ns | 直接整数比较，~1ns |
|
||||
| 刻子判断 | `t1==t2 && t2==t3` | `t1==t2 && t2==t3`（值类型） |
|
||||
| 顺子判断 | t1.Suit==t2.Suit && t2.Rank==t1.Rank+1 | `t2==t1+1 && 同花色检查` |
|
||||
| 可读性 | ✅ 一眼看出是"五万" | ❌ 需要映射回字符串 |
|
||||
| 内存 | 每个tile 16 bytes | 每个tile 4 bytes |
|
||||
|
||||
**选型结论：使用 int 编码。** 游戏引擎底层数据结构，性能和稳定性优先。4 倍内存优势 + 10 倍比较速度 + 整数排序不需要 Comparer。可读性通过 `MahjongTile.Decode()` 和常量 `T.一万` 解决，不影响核心算法路径。

### 3.4 PhaseMachine.cs (3-4 小时, ~300 行)
|
||||
|
||||
麻将的状态机比扑克复杂——有嵌套子阶段（摸牌→选择→出牌→等待他人反应）。
|
||||
|
||||
```csharp
|
||||
namespace RuleEngine.Phase;
|
||||
|
||||
public class MahjongPhaseMachine
|
||||
{
|
||||
private readonly PhaseConfig _config;
|
||||
private readonly MeldsSolver _solver;
|
||||
|
||||
public MahjongPhaseMachine(PhaseConfig config, MeldsSolver solver) { ... }
|
||||
|
||||
/// 获取当前玩家的合法操作
|
||||
public List<PlayerAction> GetLegalActions(MahjongGameState state, string playerId) { ... }
|
||||
|
||||
/// 执行操作 → 返回事件列表
|
||||
public List<GameEvent> Execute(MahjongGameState state, PlayerAction action) { ... }
|
||||
|
||||
/// 自动阶段（发牌、摸牌）
|
||||
public List<GameEvent> AutoPhase(MahjongGameState state)
|
||||
{
|
||||
switch (state.Phase)
|
||||
{
|
||||
case "deal": return ExecuteDeal(state);
|
||||
case "play" when state.SubPhase == "draw":
|
||||
return ExecuteDraw(state);
|
||||
case "settle": return ExecuteSettle(state);
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**关键流程：**
|
||||
|
||||
```
|
||||
一个完整回合:
|
||||
|
||||
1. draw (auto) → 从牌墙摸一张
|
||||
2. self_action → 玩家选择: 出牌 | 暗杠 | 加杠 | 自摸胡
|
||||
- 如果暗杠/加杠 → 回到 draw（补牌）
|
||||
- 如果出牌 → 进入 others_reaction
|
||||
3. others_reaction → 其他玩家选择: 碰 | 杠 | 胡 | 过
|
||||
- 优先级: 胡(4) > 杠(3) > 碰(2) > 过(0)
|
||||
- 如果碰/杠 → skip_draw（跳过摸牌直接出牌）
|
||||
- 如果胡 → player_eliminated（血战中移除该玩家）
|
||||
- 如果全过 → next_player
|
||||
4. 血战特殊: 有人胡后不结束，移除后继续
|
||||
```

||||

||||

```
|

|
||||
### 3.7 CapabilityRegistry.cs (30 min, ~60 行)
|
||||
|
||||
引擎启动时注册所有已实现的算法能力（见架构计划 2.0f）。
|
||||
|
||||
### 3.8 引擎扩展 — 3 个算法分支 (4-5 小时，wildcard 占 3 小时)
|
||||
|
||||
国标麻将和武汉麻将需要的额外算法分支。**wildcard 必须完整实现，不能再留接口。**
|
||||
|
||||
#### wildcard — 宝牌/癞子缺口填充式回溯（武汉麻将核心）← 必须实现
|
||||
|
||||
**不能像之前那样只写注释。** Wildcard 是武汉麻将 DSL `requires` 中声明的硬依赖，CapabilityRegistry 加载时会检查。必须实现。
|
||||
|
||||
算法核心——缺口填充式回溯：
|
||||
|
||||
```csharp
|
||||
/// 缺口填充式回溯：先用非宝牌确定性分解，差一张时用宝牌补
|
||||
public MeldsResult TryExtractMeldsWithWildcard(
|
||||
int[] tiles, int[] counts, int wildcardCount, int pairCount)
|
||||
{
|
||||
// Step 1: 找第一个非零计数的非宝牌位置
|
||||
int i = FindFirstNonZero(counts);
|
||||
if (i == -1)
|
||||
{
|
||||
// 所有非宝牌已消耗完毕
|
||||
// 剩余宝牌必须能配对或组成面子
|
||||
return FinalizeWithWildcards(wildcardCount, pairCount);
|
||||
}
|
||||
|
||||
int tile = tiles[i];
|
||||
|
||||
// Step 2: 尝试用当前牌做刻子
|
||||
if (counts[i] >= 3)
|
||||
{
|
||||
counts[i] -= 3;
|
||||
var r = TryExtractMeldsWithWildcard(tiles, counts, wildcardCount, pairCount);
|
||||
if (r != null) return r;
|
||||
counts[i] += 3;
|
||||
}
|
||||
|
||||
// Step 3: 尝试用当前牌做顺子
|
||||
// ...
|
||||
|
||||
// Step 4 (关键): 差 1 张时用宝牌补齐
|
||||
if (counts[i] >= 2 && wildcardCount >= 1 && IsValidKezi(tile))
|
||||
{
|
||||
counts[i] -= 2;
|
||||
var r = TryExtractMeldsWithWildcard(tiles, counts, wildcardCount - 1, pairCount);
|
||||
if (r != null) return FinalizeMelds(r, new Meld { Type = "kezi", Tiles = [tile,tile,-1] });
|
||||
counts[i] += 2;
|
||||
}
|
||||
|
||||
// Step 4b: 差 2 张时用 2 个宝牌补齐刻子
|
||||
if (counts[i] >= 1 && wildcardCount >= 2 && IsValidKezi(tile))
|
||||
{
|
||||
counts[i] -= 1;
|
||||
var r = TryExtractMeldsWithWildcard(tiles, counts, wildcardCount - 2, pairCount);
|
||||
if (r != null) return FinalizeMelds(r, new Meld { Type = "kezi", Tiles = [tile,-1,-1] });
|
||||
counts[i] += 1;
|
||||
}
|
||||
|
||||
// Step 4c: 顺子缺中间张用宝牌补齐
|
||||
// ...
|
||||
|
||||
// Step 5: 宝牌做将（需 258 检查）
|
||||
if (counts[i] >= 1 && wildcardCount >= 1 && pairCount == 0)
|
||||
{
|
||||
// 如果规则要求 258 将 → 检查 tile 是否是 258
|
||||
if (IsValidPair(tile, allowWildcard: true))
|
||||
{
|
||||
counts[i] -= 1;
|
||||
var r = TryExtractMeldsWithWildcard(tiles, counts, wildcardCount - 1, pairCount + 1);
|
||||
if (r != null) return r with { PairTiles = [tile, -1] };
|
||||
counts[i] += 1;
|
||||
}
|
||||
}
|
||||
|
||||
return null;
|
||||
}
|
||||
```
|
||||
|
||||
关键改动点：
|
||||
|
||||
1. **`counts` 索引扩展**：万1-9 → 0-8, 条1-9 → 9-17, 筒1-9 → 18-26, 字31-37 → 27-33。宝牌不进入 counts，单独用 `wildcardCount` 追踪。
|
||||
2. **`FinalizeWithWildcards`**：处理"非宝牌已全部消耗完，只剩宝牌"的情况。剩余宝牌数 ≥ 2w 时表示可能有 w 个宝牌对子/面子。
|
||||
3. **`IsValidPair` 扩展**：武汉麻将需检查 258 将（tile 的 rank 是 2/5/8，或者传递 `allowWildcard`）。
|
||||
4. **宝牌计数**：胡牌结果中需标记每张宝牌被用来替代了什么牌，供 ScoreEngine 计算癞子番。
|
||||
|
||||
**预计代码量：~200 行。**
|
||||
|
||||
#### wildcard 的 Capability 注册
|
||||
|
||||
```csharp
|
||||
// CapabilityRegistry — 初始化时注册
|
||||
registry.Register(new Capability
|
||||
{
|
||||
Id = "meldsolver.wildcard",
|
||||
Name = "宝牌/癞子支持（缺口填充式回溯）",
|
||||
Category = "mahjong",
|
||||
Since = "1.0.0",
|
||||
Description = "支持任意替代型宝牌：固定癞子（武汉）、翻鬼（广东）、百搭（台湾）"
|
||||
});
|
||||
```
|
||||
|
||||
注册后，武汉麻将 DSL 加载时不会再报"能力缺失"。广东麻将的可选鬼牌模式也可以复用同一套算法。
|
||||
|
||||
#### 武汉麻将 258 将检查
|
||||
|
||||
```csharp
|
||||
/// 用于 MeldsSolver 的将牌验证
|
||||
private bool IsValid258Pair(int tile, bool allowWildcard)
|
||||
{
|
||||
if (allowWildcard) return true; // 宝牌可以做任何将
|
||||
int rank = MahjongTile.Rank(tile);
|
||||
return rank == 2 || rank == 5 || rank == 8;
|
||||
}
|
||||
|
||||
// 集成到 CheckWin：
|
||||
public MeldsResult CheckWin(List<int> hand, int? wildcardTile = null, bool require258Pair = false)
|
||||
{
|
||||
// ... 先检查 wildcard 数量
|
||||
int wildcardCount = wildcardTile.HasValue
|
||||
? hand.Count(t => t == wildcardTile.Value)
|
||||
: hand.Count(MahjongTile.IsWildcard);
|
||||
|
||||
// 进入缺口填充式回溯
|
||||
var result = TryExtractMeldsWithWildcard(tiles, counts, wildcardCount, 0);
|
||||
|
||||
if (result != null && require258Pair)
|
||||
{
|
||||
// 验证将牌是 258 或由宝牌组成
|
||||
if (!result.PairTiles.All(t => IsValid258Pair(t, isWildcard: t == -1)))
|
||||
return new MeldsResult { IsWin = false };
|
||||
}
|
||||
|
||||
return result;
|
||||
}
|
||||
```
|
||||
```
|
||||
|
||||
#### all_orphans — 全不靠（国标麻将）
|
||||
|
||||
```csharp
|
||||
/// 全不靠判断：14张牌之间无任何关联
|
||||
/// 三种花色各自按 1-4-7 / 2-5-8 / 3-6-9 排列
|
||||
/// 加上东南西北中发白各一张，再加任意一对
|
||||
public MeldsResult? CheckAllOrphans(List<int> tiles)
|
||||
{
|
||||
// 1. 检查是否所有牌都是幺九牌或字牌
|
||||
// 2. 检查三种花色是否按 147/258/369 分布
|
||||
// 3. 检查字牌是否齐全
|
||||
// 约 60 行
|
||||
}
|
||||
```
|
||||
|
||||
#### double_dragon — 一色双龙会（国标麻将）
|
||||
|
||||
```csharp
|
||||
/// 一色双龙会：同花色1-9各两张，14张从18张中取
|
||||
/// 实质是面子分解的特殊变体
|
||||
public MeldsResult? CheckDoubleDragon(List<int> tiles)
|
||||
{
|
||||
// 1. 检查是否全部同花色
|
||||
// 2. 检查是否1-9各有至少2张
|
||||
// 3. 尝试拆分成 2组龙（123/456/789）+ 2组龙 + 任意一对
|
||||
// 约 50 行
|
||||
}
|
||||
```
|
||||
|
||||
**在 CheckWin 中集成：**
|
||||
|
||||
```csharp
|
||||
public MeldsResult CheckWin(List<int> hand, int? newTile = null)
|
||||
{
|
||||
var tiles = new List<int>(hand);
|
||||
if (newTile != null) tiles.Add(newTile.Value);
|
||||
if (tiles.Count != 14) return new MeldsResult { IsWin = false };
|
||||
|

tiles.Sort();
|

// 1. 七对
|

var sevenPairs = TrySevenPairs(tiles);
|

if (sevenPairs != null) return sevenPairs;
|

// 2. 十三幺
|

return orphansResult;
|

// 3. 全不靠（国标） ← 新增
|
||||
var allOrphans = CheckAllOrphans(tiles);
|

if (allOrphans != null) return allOrphans;
|

// 4. 一色双龙会（国标） ← 新增
|
||||
var doubleDragon = CheckDoubleDragon(tiles);
|

if (doubleDragon != null) return doubleDragon;
|

// 5. 标准胡牌（回溯搜索）+ 可选 wildcard 模式
|

## 五、Demo 控制台程序 (1.5 小时)
|
||||
|
||||
### 5.1 Room.cs (~200 行)
|
||||
|
||||
```csharp
|
||||
namespace Demo;
|
||||
|
||||
public class MahjongRoom
|
||||
{
|
||||
private readonly RuleSet _rules;
|

public void Run()
|

deck.Shuffle();
|

}
|

```
|
||||
|
||||
### 5.2 Program.cs — 交互+自动双模式
|
||||
|
||||
默认交互模式（每步暂停），`--auto` 切换为自动模式（压测用）。
|
||||
|
||||
```csharp
|
||||
var caps = new CapabilityRegistry();
|
||||
caps.Register("meldsolver.standard_win");
|
||||
caps.Register("meldsolver.seven_pairs");
|
||||
caps.Register("phase.mahjong_turn");
|
||||
caps.Register("phase.parallel_elimination");
|
||||
caps.Register("phase.priority_arbitration");
|
||||
caps.Register("scoring.fan_exclusion");
|
||||
caps.Register("scoring.pre_hooks");
|
||||
|
||||
var loader = new DslLoader(caps);
|
||||
var rules = loader.Load("dsl-examples/xuezhandaodi.yaml");
|
||||
|
||||
bool autoMode = args.Contains("--auto");
|
||||
Console.WriteLine($"=== 麻将规则引擎 Demo — 四川血战到底 === ({(autoMode ? "自动模式" : "交互模式")})");
|
||||
Console.WriteLine();
|
||||
|
||||
var room = new MahjongRoom(rules, new[] { "AI-东", "AI-南", "AI-西", "AI-北" }, autoMode);
|
||||
room.Run();
|
||||
```
|
||||
|
||||
### 5.3 交互模式输出示例（默认）
|
||||
|
||||
每一步暂停，显示所有玩家的完整手牌。按任意键继续下一步。

### 5.4 自动模式（压测用 `--auto`）
|
||||
|
||||
自动模式跳过所有交互，AI 之间全自动对打，只在结算时输出一行结果：
|

|
||||
```
|
||||
$ dotnet run -- --auto
|

```
|
||||
|

Room.Run() 根据 `autoMode` 参数决定是否在每步后等待按键：
|

```csharp
|

while (!IsFinished)
|

RenderFullHands(); // 显示所有玩家的完整手牌
|

Console.ReadKey(true); // 等待按键
|

```
|

### 6.3 压力测试
|

### 6.8 测试文件总数预计
|
||||
|
||||
新增 4 个测试类别后：
|
||||
|
||||
| 类别 | 用例数 |
|
||||
|------|-------|
|
||||
| 数据结构 (Tile/Deck/GameState) | 6 |
|
||||
| MeldsSolver (胡牌+番型+听牌) | 24 |
|
||||
| PhaseMachine | 12 |
|
||||
| ScoreEngine | 8 |
|
||||
| DslLoader (含错误处理) | 7 |
|
||||
| 番型互斥专项 | 5 |
|
||||
| 听牌判断专项 | 4 |
|
||||
| 错误处理 | 6 |
|
||||
| 性能 | 2 |
|
||||
| 集成测试 | 3 |
|
||||
| 压力测试 | 1 |
|
||||
| **总计** | **92** |
|
||||
|
||||
---
|
||||
|
||||
## 七、Demo 完成标准
|
||||
|
||||
- [ ] `dotnet test` — 92+ 个测试用例全部绿色（含 wildcard 缺口填充、258将、全不靠、双龙会、国标测试）
|
||||
- [ ] `dotnet run --project Demo` — 交互模式：四川血战（108张，缺一门+血战+查叫）
|
||||
- [ ] `dotnet run --project Demo -- --dsl guangdong` — 广东鸡平胡（136张，花牌+吃+番型三级）
|
||||
- [ ] `dotnet run --project Demo -- --dsl guobiao` — 国标麻将（144张，81番种+≥8番起胡）
|
||||
- [ ] `dotnet run --project Demo -- --dsl wuhan` — 武汉麻将（136张，红中癞子+258将+缺口填充回溯）
|
||||
- [ ] **热切换验证**：同一进程，四川→广东→国标→武汉串行跑，不需要重新编译、不需要重启
|
||||
- [ ] 结算验证：四种麻将各自总分 = 0（零和）、牌数守恒（108/136/144/136）
|
||||
- [ ] 番型互斥正确：四川（清一色⊃缺一门）、广东（七对 vs 对对胡）、国标（81 番种互斥图形式化验证通过）
|
||||
- [ ] **wildcard 验证**：1张癞子补刻子、2张补齐、3张补面子+将、258将正确、癞子计分正确
|
||||
- [ ] `dotnet run --project Demo -- --auto --count 1000` — 自动模式连续 1000 局零报错
|
||||
|
||||
## 八、Demo 之后的路
|
||||
|
||||
```
|
||||
Demo ✅ 三种麻将 + 引擎扩展 + 热切换
|
||||
↓
|
||||
Unity 前端: 麻将牌面渲染 + 出牌操作 UI
|
||||
↓
|
||||
Python AI 服务: MCTS 搜索 + LLM Agent
|
||||
↓
|
||||
CSharpScript 沙盒: 自定义计分/比较函数
|
||||
↓
|
||||
10+ 麻将玩法 DSL + CI 压测
|
||||
