[]Animation 使用疑问

清理问题 内存没有发生变化
private onBtnClick(): void {
this.body = new Laya.Animation();
this.body.y = -100;
this.body.interval = 50;
this.addChild(this.body);
this.body.play(0, true, "hero_fly");
}
private body: Laya.Animation;
private onBtn2Click(): void {
this.body.destroyChildren();
this.body.clear();
this.body.destroy();
}
调试面板中的sprite个DrwaCall都有变化，但是CurMern么有发出变化，是否正常？

构造时创建
  constructor() {
        this.aniBody = new Animation();
        this.aniBody.interval = this.frameNum;
        Map.getInstance().heroSprVI.sprCon.addChild(this.aniBody);

        this.aniWeapon = new Animation();
        this.aniWeapon.interval = this.frameNum;
        Map.getInstance().heroSprVI.sprCon.addChild(this.aniWeapon);

        this.aniSkillEff = new Animation();
        this.aniSkillEff.interval = this.frameNum;
        Map.getInstance().heroSprVI.sprCon.addChild(this.aniSkillEff);

        this.aniWing = new Animation();
        this.aniWing.interval = this.frameNum;
        Map.getInstance().heroSprVI.sprCon.addChild(this.aniWing);
}
创建缓存
 urls.forEach((urlPath, index) => {
            this.xxxx.loadAtlas(urlPath, null, lv + "_" + actionName + "_" + index);
        });
 
播放时大概
playAniBody(actionName: string, direction: number, completeFun: Function = null): void {
         this.aniBody.destroyChildren();
         this.aniBody.clear();

        let loopPlay: boolean = true;
        let key: string = actionName + "_" + Math.abs(direction);
        this.aniBody.play(0, loopPlay, key);
        var bound: Laya.Rectangle = this.aniBody.getBounds();
        this.aniBody.pivot(bound.width / 2, bound.height / 2);

        if (direction < 0) {
            this.aniBody.scaleX = -1;
        } else {
            this.aniBody.scaleX = 1;
        }
    }
每改变一个方向CurMern都爆涨50M这样（我的资源body，weapon，skillEff，wing也差不多50M），我在任务管理器中查看chrome的内存大概60M而已，请问内存这一块什么看靠谱点！谢谢
