设置碰撞组件

• 3种组件类型，矩形碰撞，圆形碰撞， 多边形碰撞

开启碰撞检测

start() {//开启碰撞管理器let cm = cc.director.getCollisionManager()cm.enabled = true//绘制碰撞检测边界线。用于调试cm.enabledDebugDraw = true//绘制精灵的边界cm.enabledDrawBoundingBox = true//鼠标（MOUSE_DOWN）、或手指拖拽人物移动this.node.on(cc.Node.EventType.TOUCH_START, () => {this.isFocus = true})this.node.on(cc.Node.EventType.TOUCH_END, () => {this.isFocus = false})this.node.on(cc.Node.EventType.TOUCH_MOVE, (e: cc.Event.EventMouse) => {if (this.isFocus) {this.node.setPosition(e.getLocation())}})}

碰撞检测的几个回调

• 注意和updae在同一级

// update (dt) {}//碰撞检测，发生碰撞onCollisionEnter(other: cc.Collider, self: cc.Collider): void {cc.log("发生碰撞" + other.tag)}//碰撞检测，持续碰撞onCollisionStay(other: cc.Collider, self: cc.Collider): void {cc.log("持续碰撞" + other.tag)}//碰撞检测，持续碰撞onCollisionExit(other: cc.Collider, self: cc.Collider): void {cc.log("结束碰撞" + other.tag)}
