+| 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) ×

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) │ +│ │ +│ 1. state → 渲染 │ ← 唯一的引擎差异在这里 +│ Canvas: drawImage() │ +│ Cocos: cc.instantiate() │ +│
