【cocos2dx-js 学习分享 七】游戏遮罩

//创建游戏遮罩
this.clip=new cc.ClippingNode();
this.clip.setInverted(true);
this.clip.setAlphaThreshold(0.0);
this.addChild(this.clip,this.kTagClipNode );

var back=new cc.LayerColor(cc.color(0,200,0));
this.clip.addChild(back);



var nodef=new cc.Node();
var close=new cc.Sprite(res.CloseNormal_png);
nodef.addChild(close);
nodef.setPosition(cc.p(size.width/2,size.height/2));
this.clip.setStencil(nodef);

this.tip = new cc.Sprite(res.tip_png);
this.tip.setScale(0.5);
this.tip.setRotation(60);
this.tip.setPosition(cc.p(size.width/2-70,size.height/2+50));
this.addChild( this.tip,this.kTagTip);

this.tip.runAction(cc.repeatForever( cc.sequence( cc.scaleBy(0.25,0.95),cc.scaleTo(0.25,0.5) ) ));
