[bug]ClippingNode真机和模拟器效果不一致

代码:

var self = this;
 this._light = new cc.Sprite("res/s.png");
 var enemy = new cc.Sprite();
 var dh = sp.SkeletonAnimation.create("res/robot/enemy.json","res/robot/enemy.atlas");
 dh.setAnimation(0,"idle",true); 

 self._light.anchorY = 0;

 self._light.scaleX = 8;
 self._light.scaleY = 8;

 var clipNode = new cc.ClippingNode();
 clipNode.setStencil(dh);
 clipNode.setPositionX(300);
 clipNode.setPositionY(0);

 clipNode.setInverted(false);
 clipNode.setAlphaThreshold(0.1);
 clipNode.name = "clipNode";
 clipNode.addChild(dh);
 clipNode.addChild(this._light);
 this.addChild(clipNode);
