}

4.绑定Canvas 

 2.消除障碍

GameController.ts

onLoad() {cc.game.setFrameRate(90)//恢复游戏，避免游戏暂停导致无法继续cc.director.resume();//给Canvas绑定事件this.canvas.on(cc.Node.EventType.TOUCH_MOVE, this.onMove, this)//开启碰撞引擎let manager = cc.director.getCollisionManager();manager.enabled = true;//如果要调试if (this.is_debug == true) {// 是否绘制碰撞组件的形状，默认为不绘制manager.enabledDebugDraw = true;//是否绘制碰撞组件的包围盒，默认为不绘制manager.enabledDrawBoundingBox = true;}//创建障碍物this.create_barrier();this.cre_bar_f = (this.barrier_height / this.barrier_speed) + Math.random() * this.generation_interval;}

六、Buff

1.生成buff

1.新建显示获得buff类型节点

2.新建Buff脚本，新建buff预制资源

 3.新建buff子节点
