Question

如何在屏幕上顯示圖片，幾秒鐘後刪除iteself？ 就像遊戲開始時的教程，我知道計時器處理程序是我應該考慮的事情，但是如何做到這一點？

Answer 1

TimerHandler是一個簡單的選擇。

final Sprite picture = ... 
.... 
TimerHandler removeHandler = new TimerHandler(secondsToRemove, new ITimerCallback() { 
    @Override 
    public void onTimePassed(final TimerHandler pHandler) { 
     picture.unregisterUpdateHandler(pHandler); 
     picture.setVisible(false); 
     //Or: 
     scene.detachChild(picture); 
     //You should use the second option, as making the picture invisible does not detach it from your game. 
    } 
}); 
picture.registerUpdateHandler(removeHandler);
