[code]var scene = Laya.stage.addChild(new Laya.Scene());
scene.once(Laya.Event.HIERARCHY_LOADED, null, function (sprite) {
console.log("scene HIERARCHY_LOADED");
});
scene.once(Laya.Event.LOADED, null, function (sprite) {
console.log("scene LOADED");
});[/code]HIERARCHY_LOADED 和 LOADED有什么区别?为什么对scene不起作用?
