Laya Matter颠球小游戏

游戏功能是用TS实现的 

一共两个类：

    游戏入口：Main.ts 

    游戏逻辑：Ball.ts

    处理微信逻辑：Platform.ts

开发过程中 调用小游戏wx方法 报错 所以定义了 Platform.ts 并且 在bin目录下增加Platform.js 文件

Platform.js  代码如下

class WechatPlatform {
    Instance = wx;
}
window.platform = new WechatPlatform();

Platform.ts

/** 
* 平台数据接口。
* 由于每款游戏通常需要发布到多个平台上，所以提取出一个统一的接口用于开发者获取平台数据信息
* 通过这种方式封装平台逻辑，以保证整体结构的稳定
*/
declare interface Platform {
    Instance;
}

class DebugPlatform implements Platform {
    Instance = {};
}

if (!window.platform) {
    window.platform = new DebugPlatform();
}
declare let platform: Platform;
declare interface Window {
    platform: Platform;
}

Main.ts

import Handler = Laya.Handler;
import Loader  = Laya.Loader;
import Point   = Laya.Point;
//主函数入口
class Main {
    constructor()
    {
        //修改sharedCanvas 大小 用于处理排行榜
        if(Laya.Browser.window.sharedCanvas){
            Laya.Browser.window.sharedCanvas.width  = Laya.stage.width;
            Laya.Browser.window.sharedCanvas.height = Laya.stage.height;
        }
        
        //加载资源
        Laya.loader.load([
            { url: "https://lg-na2wup38-1256823928.cos.ap-shanghai.myqcloud.com/background.jpg"  , type: Loader.IMAGE },
            { url: "https://lg-na2wup38-1256823928.cos.ap-shanghai.myqcloud.com/qiu.png"         , type: Loader.IMAGE },
