Question

我需要帮助解决一个涉及TimerHandlers的奇怪问题。出于某种原因，当我在我的定时器组上调用unregisterUpdateHandler时，它们不会在第一次传递时被删除。这个问题让我疯狂，因为它对我来说完全没有意义。我只添加了一次定时器，并在重新启动我的关卡时取消注册。如果我没有注册一组新的计时器，旧的计时器会持续存在，好像我从未取消注册它们一样，直到我再次重新启动这个级别然后它们终于消失了。还有其他人遇到过这个问题吗？

这些都属于同一类

@Override
public void createScene() {

    createBackground();
    createHUD();
    createPhysics();

    if(!firstTry)
    {
        createSprites();
        firstTry = true;

    }
    loadLevel(1);
    createGameOverText();
    loadData();
    //levelCompleteWindow = new LevelCompleteWindow(vbom);

    setOnSceneTouchListener(this);

}

public void createSprites()
{
    updater =  new TimerHandler(1f, new ITimerCallback() 
    {
        public void onTimePassed(final TimerHandler pTimerHandler) 
        {

            updateTime();
            /*if(timeRemaining <=0)
            {
                player.onDie();
            }*/
            pTimerHandler.reset();
        }
    });
    itemMaker = new TimerHandler(5f, new ITimerCallback() 
    {
        public void onTimePassed(final TimerHandler pTimerHandler) 
        {
            createItem();
            pTimerHandler.reset();
        }
    });
    enemyMaker = new TimerHandler(2.5f, new ITimerCallback() 
    {
        public void onTimePassed(final TimerHandler pTimerHandler) 
        {
            createEnemy();
            pTimerHandler.reset();
        }
    });

    player = new Player(SCREEN_WIDTH/10,SCREEN_HEIGHT-ResourceManager.getInstance().player_region.getHeight(), vbom, camera, physicsWorld)
    {

        @Override
        public void onDie() {
            // TODO Auto-generated method stub
            if (!gameOverDisplayed)
            {
                displayGameOverText();
                saveData();
                createMenuChildScene();
                //Log.d("TEST","CALLED");
                physicsWorld.unregisterPhysicsConnector(this.fall);
                //unregisterUpdateHandler(updater);
                //unregisterUpdateHandler(itemMaker);
                //unregisterUpdateHandler(enemyMaker);
                //unregisterUpdateHandler(increase);
            }
        }

    };
    this.registerUpdateHandler(updater);
    this.registerUpdateHandler(itemMaker);
    this.registerUpdateHandler(enemyMaker);
    //this.registerUpdateHandler(increase);
}

当播放器在没有重新加载类

的情况下重新启动场景时，会调用此方法

private void cleanUp()
{
    this.detachChildren();
    menuChildScene.back();

    timeRemaining = 30;
    totalTime = 0;
    isRunning=false;
    gameOverDisplayed = false;
    //Log.d("TEST","PLayer Y:"+ player.getY());
    //player.setY(SCREEN_HEIGHT-ResourceManager.getInstance().player_region.getHeight());
    //player.
    //updater.reset();
    //itemMaker.reset();
    //enemyMaker.reset();
    //increase.reset();
    this.unregisterUpdateHandler(updater);
    this.unregisterUpdateHandler(itemMaker);
    this.unregisterUpdateHandler(enemyMaker);
    //this.unregisterUpdateHandler(increase);
    Log.d("TEST","Handlers Unregistered");
    //physicsWorld.registerPhysicsConnector(player.fall);
    player = new Player(SCREEN_WIDTH/10,SCREEN_HEIGHT-ResourceManager.getInstance().player_region.getHeight(), vbom, camera, physicsWorld)
    {

        @Override
        public void onDie() {
            // TODO Auto-generated method stub
            if (!gameOverDisplayed)
            {
                displayGameOverText();
                saveData();
                createMenuChildScene();
                //Log.d("TEST","CALLED");
                physicsWorld.unregisterPhysicsConnector(this.fall);
                //unregisterUpdateHandler(updater);
                //unregisterUpdateHandler(itemMaker);
                //unregisterUpdateHandler(enemyMaker);
                //unregisterUpdateHandler(increase);
            }
        }

    };
    //this.unregisterUpdateHandlers(pUpdateHandlerMatcher);
}

如果需要，我会添加更多代码，但这些是引用TimerHandler的唯一实例。正如你所看到的，我曾尝试多次取消注册计时器，但结果是相同的，计时器直到第二次通过/死亡才被删除

TimerHandler重复并且无法在andengine中注销
