Cocos Creator 开发微信小游戏 打包上线

1.首先在制作小游戏时我们需要下载Cocos Creator游戏开发工具 下载连接： 下载后无脑下一步安装，打开即可！ 那为啥我们选择Cocos Creator， 看图：

本游戏只用到一个scene场景, 并只用一个ts实现游戏的所有逻辑。 MainController.ts代码如下:

const {
          
   ccclass, property} = cc._decorator;

@ccclass
export default class NewClass extends cc.Component {
          
   

    //小鸟飞行动画节点
    @property(cc.Sprite)
    bird0: cc.Sprite = null;
    @property(cc.Sprite)
    bird1: cc.Sprite = null;
    @property(cc.Sprite)
    bird2: cc.Sprite = null;
    @property(cc.Sprite)
    bird3: cc.Sprite = null;

    //小鸟父容器节点
    @property(cc.Node)
    birdParent: cc.Node = null;

    //背景
    @property(cc.Node)
    bg0: cc.Node = null;
    @property(cc.Node)
    bg1: cc.Node = null;


    //管子
    @property(cc.Node)
    pipeParent0: cc.Node = null;
    @property(cc.Node)
    pipeParent1: cc.Node = null;
    @property(cc.Node)
    pipeParent2: cc.Node = null;

    //分数
    @property(cc.Label)
    lbScore: cc.Label = null;

    //结束图片节点
    @property(cc.Node)
    nodeGameOver: cc.Node = null;

    //开始按钮
    @property(cc.Button)
    btnStart: cc.Button = null;

    // onLoad () {}

    time: number = 0;   //距离上次切换显示的小鸟时间
    speed: number = 0;  //负数向下坠落的速度，正数向上的速度
    score: number = 1;  //得分
    isGameStart: boolean = false;   //游戏是否开始

    //初次进入游戏时触发start方法
    start() {
          
   
        //管道的初始位置
        let pipeStartOffsetX: number = 200;
        let spaceX = (288 + 52) / 3
        this.pipeParent0.x = pipeStartOffsetX + spaceX * 0;
        this.pipeParent1.x = pipeStartOffsetX + spaceX * 1;
        this.pipeParent2.x = pipeStartOffsetX + spaceX * 2;
    }

    //游戏每执行一针时就触发一次update方法
    update(dt: number) {
          
   
        let timeTmp = this.time + dt;
        this.time = timeTmp;

        //控制小鸟的显示隐藏，计算流逝的时间大于0.5s值时，就切换小鸟当前显示的小鸟
        if (this.time > 0.5) {
          
   
            if (this.bird0.node.active) {
