[]如何彻底关闭开放域排行榜

//移除排行榜

_proto.closeCloudStorage = function () {

    if (LayaSample.refract && Laya.stage.contains(LayaSample.refract)) LayaSample.refract.removeSelf();//折射层移除舞台

    if (Laya.stage.contains(LayaSample.spriteLeaderboard)) {//从舞台移除

        LayaSample.textureLeaderboard.bitmap.alwaysChange = false;//将消耗性能的这句话关闭

        LayaSample.spriteLeaderboard.removeSelf();//移除精灵

    }



    LayaSample.textureLeaderboard.destroy(false);//销毁纹理

    LayaSample.spriteLeaderboard.destroy(true);//销毁精灵



    LayaSample.sharedCanvas = null;//wx.getOpenDataContext().canvas的引用

    LayaSample.textureLeaderboard = null;//纹理引用

    LayaSample.spriteLeaderboard = null;//精灵引用



    if (window.wx) wx.triggerGC();//微信垃圾回收

}

//写这个么多,怎么还是卡呢???
