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。
