cocos2d-js 遮挡层

cc.ModelLayerColor = cc.LayerColor.extend({
  m_touchListener:null,
  ctor:function(){
    this._super();
    var touchListener = {
      event: cc.EventListener.TOUCH_ONE_BY_ONE,
      swallowTouches: true,
      onTouchBegan: this.onTouchBegan
    };
    cc.eventManager.addListener(touchListener, this);
    this.m_touchListener = touchListener;
  },
  onTouchBegan:function(touch, event) {
    var target = event.getCurrentTarget();
    if(!target.isVisible() || (!this.isTouchInside(target,touch))){
      return false;
    }
    return true;
  },
  isTouchInside: function (owner,touch) {
    if(!owner || !owner.getParent()){
      return false;
    }
    var touchLocation = touch.getLocation(); // Get the touch position
    touchLocation = owner.getParent().convertToNodeSpace(touchLocation);
    return cc.rectContainsPoint(owner.getBoundingBox(), touchLocation);
  }
});

这里要把swallowTouches设置为true，这样onTouchBegan返回true才能够吞噬触摸，不继续往优先级更低的层传递，从而实现遮挡层。
