用cc.game.addPersistRootNode(this.node);
设置完用console.log("is Persist node " + cc.game.isPersistRootNode(this.node) ); 返false
新scene获取所children像没
var children = cc.director.getScene().getChildren();
console.log("children name is ");
for (var index = 0; index < children.length; index ++){
console.log(children[index].name);
}
查看发现没前node啊
