+# boardgame-phaser
+
+基于Phaser3/boardgame-core的游戏框架
+
+## 概述
+
+项目使用pnpm monorepo管理，包含以下包：
+- `framework`：通用框架
+- `boop-game`：boop样例
+- `sample-game`：tic tac toe样例
+
+游戏应当使用vite构建，基于`preact/signals`进行状态管理，使用`phaser3`实现游戏功能。
+
+## boardgame-core
+
+项目使用`boardgame-core`进行游戏定义。
+`boardgame-core`的内容可以在`framework/node_modules/boardgame-core`找到。
+这个文件夹被.gitignore忽略，查看时需要绕开这一限制。
+
+## 编写游戏
+
+游戏逻辑以gameModule的形式定义：
+
+```typescript
+import {createGameCommandRegistry, IGameContext} from "boardgame-core";
+
+// 创建mutative游戏初始状态
+export function createInitialState(): GameState {
+    //...
+}
+
+// 运行游戏
+export async function start(game: IGameContext<GameState>) {
+    // ...
+}
+
+// 可选
+export const registry = createGameCommandRegistry();
+```
+
+使用以下步骤创建游戏：
+
+### 1. 定义状态
+
+游戏状态使用一个大的`mutative`对象来描述，所有的状态更新通过`game.produce`或`game.produceAsync`来实现。
+
+通常使用一个`regions: Record<string, Region>`和一个`parts: Record<string, Part<TMeta>>`来记录桌游物件的摆放。
+
+### 2. 定义流程
+
+使用`async function start(game: IGameContext<GameState>)`作为入口。
+
+需要等待玩家交互时，使用`await game.prompt(schema, validator, player)`。
+
