我正在制作小气球游戏。气球随机弹出并在一段时间后消失。当我点击它们时，我想让它们消失并显示 +1 而不是气球。当我点击气球时，我想拆下气球精灵。我的问题是当我在代码中调用 sprite.detachSelf() 时，精灵只是消失了，但实际上精灵并没有被删除。它只会变得不可见。当我再次单击该位置时，气球会出现，即使在气球消失后它也会显示+1。这意味着我认为气球没有正确分离。
这是我的代码：

//this.mEngine.registerUpdateHandler(new FPSLogger());

getVertexBufferObjectManager());

"00 : 60", getVertexBufferObjectManager());
scene.attachChild(textTime);
