echo # ECS Framework WASM for Cocos Creator
|
||||
echo.
|
||||
echo ## 文件说明
|
||||
echo.
|
||||
echo - `%WASM_NAME%.ts` - WASM 胶水代码（原 JS 文件重命名）
|
||||
echo - `%WASM_NAME%_bg.bin` - WASM 二进制文件（原生端使用）
|
||||
echo - `%WASM_NAME%_bg.wasm` - WASM 二进制文件（微信小游戏使用）
|
||||
echo - `%WASM_NAME%.d.ts` - TypeScript 类型定义
|
||||
echo.
|
||||
echo ## 在 Cocos Creator 中使用
|
||||
echo.
|
||||
echo ### 1. 导入文件到项目
|
||||
echo.
|
||||
echo 1. 将 `%WASM_NAME%.ts` 放到 assets/scripts/ 目录
|
||||
echo 2. 将 `%WASM_NAME%_bg.bin` 导入为 BufferAsset（原生端）
|
||||
echo 3. 将 `%WASM_NAME%_bg.wasm` 放到微信小游戏构建目录
|
||||
echo.
|
||||
echo ### 2. 组件代码示例
|
||||
echo.
|
||||
echo ```typescript
|
||||
echo import { _decorator, Component, BufferAsset } from 'cc';
|
||||
echo import { initSync } from './%WASM_NAME%';
|
||||
echo.
|
||||
echo const { ccclass, property } = _decorator;
|
||||
echo.
|
||||
echo @ccclass('WasmLoader'^)
|
||||
echo export class WasmLoader extends Component {
|
||||
echo @property(BufferAsset^)
|
||||
echo wasmAsset!: BufferAsset;
|
||||
echo.
|
||||
echo start(^) {
|
||||
echo this.initWasm(^);
|
||||
echo }
|
||||
echo.
|
||||
echo private async initWasm(^) {
|
||||
echo try {
|
||||
echo // 检查平台
|
||||
echo if (typeof wx !== 'undefined'^) {
|
||||
echo // 微信小游戏环境
|
||||
echo initSync("/%WASM_NAME%_bg.wasm"^);
|
||||
echo } else {
|
||||
echo // 原生端/浏览器环境
|
||||
echo const wasmBuffer = this.wasmAsset?.buffer(^);
|
||||
echo if (wasmBuffer^) {
|
||||
echo initSync(wasmBuffer^);
|
||||
echo } else {
|
||||
echo console.error('WASM 资源未正确加载'^);
|
||||
echo return;
|
||||
echo }
|
||||
echo }
|
||||
echo
|
||||
echo console.log('✅ ECS WASM 模块初始化成功'^);
|
||||
echo
|
||||
echo // 这里可以开始使用 WASM 导出的函数
|
||||
echo // 例如: wasmFunction(^);
|
||||
echo
|
||||
echo } catch (error^) {
|
||||
echo console.error('❌ WASM 初始化失败:', error^);
|
||||
echo console.log('↪️ 将使用 JavaScript 实现'^);
|
||||
echo }
|
||||
echo }
|
||||
echo }
|
||||
echo ```
|
||||
echo.
|
||||
echo ### 3. 微信小游戏配置
|
||||
echo.
|
||||
echo 使用 build-templates 自动复制 WASM 文件：
|
||||
echo.
|
||||
echo 1. 在项目 build-templates/wechatgame/ 目录下创建构建脚本
|
||||
echo 2. 构建时会自动复制 %WASM_NAME%_bg.wasm 到发布目录
|
||||
echo.
|
||||
echo ## 注意事项
|
||||
echo.
|
||||
echo 1. 确保在使用 ECS 系统前初始化 WASM 模块
|
||||
echo 2. 原生端使用 .bin 文件，微信小游戏使用 .wasm 文件
|
||||
echo 3. 如果 WASM 初始化失败，框架会自动回退到 JavaScript 实现
|
||||
echo 4. WASM 主要优化查询性能，对大多数应用场景提升有限
|
||||
echo.
|
||||
echo ## 重新构建
|
||||
echo.
|
||||
echo 运行 `build-cocos.bat` 重新编译最新的 WASM 模块

||||

|

echo 💡 下一步：
|

echo 1. 将文件导入到 Cocos Creator 项目
|
||||
echo 2. 参考 README.md 集成到游戏中
|
||||
echo 3. 对于微信小游戏，使用 build-templates 自动复制 WASM 文件
