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:@H_502_32@false,
onTouchBegan:@H_502_32@this.onTouchBegan,
onTouchMoved:@H_502_32@this.onTouchMoved,
onTouchEnded:@H_502_32@this.onTouchEnded
},@H_502_32@this);

3、实现触摸机制，代码：

 onTouchBegan:@H_502_32@function(touch,event){
 //cc.log("你点击了当前的屏幕！");  @H_502_32@var target = event.getCurrentTarget();
 @H_502_32@var mx = Math.abs((touch.getLocation().x - 5) - target._head.now_col*63);
 @H_502_32@var my = Math.abs((touch.getLocation().y - 300) - target._head.now_row*63);
 @H_502_32@if(mx > my){//左右移动  @H_502_32@if((touch.getLocation().x - 5) > target._head.now_col*63){
 //向右移动  dir = SNAKE_DIR.RIGHT;
 }@H_502_32@else{
 //向左移动  dir = SNAKE_DIR.LEFT;
 }

 }@H_502_32@else{//上下移动  @H_502_32@if((touch.getLocation().y - 300) > target._head.now_row*63){
 //向上移动  dir = SNAKE_DIR.UP;
 }@H_502_32@else{
 //向下移动  dir = SNAKE_DIR.DOWN;
 }

 }
},
