Cocos2d-JS切换场景与切换特效

var HelloWorldLayer = cc.Layer.extend({
sprite:null,
ctor:function () {
//////////////////////////////
// 1. super init first
this._super();

var size=cc.winSize;
//旧场景
var background=new cc.Sprite(res.CloseNormal_png);
background.setPosition(size.width/2,size.height/2);
this.addChild(background);

this.scheduleOnce(function(f){
//创建新场景
var newScene=new cc.Scene();
var newBackground=new cc.Sprite(res.HelloWorld_png);
newBackground.setPosition(size.width/2,size.height/2);
newScene.addChild(newBackground);
//替换场景
cc.director.runScene(newScene);
},3);

return true;
}
});

var HelloWorldScene = cc.Scene.extend({
onEnter:function () {
this._super();
var layer = new HelloWorldLayer();
this.addChild(layer);
}
});

//渐变替换
var transition=new cc.TransitionCrossFade(1,newScene);
cc.director.runScene(transition);

//翻页替换
var transition=new cc.TransitionPageTurn(1,newScene,false);
cc.director.runScene(transition);
