Cocos2d-js04_游戏触摸交互的监听和实现

Cocos2d-js04_游戏触摸交互的监听和实现

1、定义触摸函数,注册监听对象及回调方法,代码:

   //创建监听对象,回调方法  

cc.eventManager.addListener({
    event:cc.EventListener.TOUCH_ONE_BY_ONE,
    swallowTouches:false,
    onTouchBegan:this.onTouchBegan,
    onTouchMoved:this.onTouchMoved,
    onTouchEnded:this.onTouchEnded
},this);

 

3、实现触摸机制,代码:

  onTouchBegan:function(touch,event){
    //cc.log("你点击了当前的屏幕!");     var target = event.getCurrentTarget();
    var mx = Math.abs((touch.getLocation().x - 5) - target._head.now_col*63);
    var my = Math.abs((touch.getLocation().y - 300) - target._head.now_row*63);
    if(mx > my){//左右移动         if((touch.getLocation().x - 5) > target._head.now_col*63){
            //向右移动             dir = SNAKE_DIR.RIGHT;
        }else{
            //向左移动             dir = SNAKE_DIR.LEFT;
        }

    }else{//上下移动         if((touch.getLocation().y - 300) > target._head.now_row*63){
            //向上移动             dir = SNAKE_DIR.UP;
        }else{
            //向下移动             dir = SNAKE_DIR.DOWN;
        }

    }
},
