我有一個應用程序，我正在使用AS3爲iOS和Android開發。我目前在這個項目中遇到了幾個性能問題。這是我第一個應用程序和遊戲。所以任何類型的反饋或洞察力都非常感謝。我的比賽是一個越野自行車比賽。它允許用戶按下一個按鈕（gasPress）向上滑輪，另一個按鈕（制動器）向下滑動。一旦按下「gasPress」按鈕，布爾型「holdGas」被設置爲true。在我的「gameLoop」（Enter_Frame事件）中，自行車向上旋轉，如果「holdGas」等於true。按壓剎車的代碼是一樣的，只是它將自行車旋轉。我的建築物在屏幕上滑動，造成了自行車移動的錯覺。構建影片剪輯緩存爲位圖。我使用了同一建築物影片剪輯的兩個實例。一旦第一個剪輯從舞臺上滑落，它將放在另一個之後。在一個循環的機制大聲笑。我遇到的這個問題是，當我按下「gasPress」按鈕時，它在前輪/向上旋轉之前滯後。當它滯後時，在後臺移動的建築物將跳過。它每次都發生。所以如果你繼續點擊gasPress（這是遊戲的一部分），屏幕上的物體會不斷跳躍。它使遊戲無法播放。我已經通過完全刪除代碼來向上/向下移動自行車來測試按鈕，遊戲仍然會跳過。當氣體被按下並且自行車向上旋轉時，我注意到更多的跳過或滯後。我現在有幀速率設置爲32，它也做了同樣在24當我按下按鈕時，我的遊戲滯後

如果我的理解它是正確的，即使沒有氣體，你也經歷了滯後？我最好的猜測是你對待移動背景的方式。嘗試刪除背景正在移動，然後嘗試徹底刪除背景，看看會發生什麼，然後回報:)通常，您的代碼沒有任何明顯的錯誤。您可能需要刪除「cacheAsBitmap」，因爲這會導致額外的工作，除非您有一個複雜的形狀。這看起來像一個「試驗和錯誤」的方法，所以只是嘗試刪除一些東西，看看它是否正常工作 – 2014-10-19 00:11:11
@DanielMesSer謝謝你的幫助。遊戲實際上運行非常平穩，直到按下這些按鈕。 （包括建築運動）它然後滯後。在按下按鈕之前，我的口吃會有點週期性，但沒有任何不利之處。絕對不會像按下按鈕時那樣接近。我把建築物拿出來，遊戲看起來很棒。我將嘗試移動他們使用+ =而不是時間增加x，看看它是如何工作的。你能想到的其他方法嗎？ – rtpenick 2014-10-19 01:53:08
@DanielMesSer使用+ =移動建築物x =原來是最差的10倍。當按下按鈕時，所有東西都會靜止不動。使用+ =方法取決於幀速率。如果談到一個立場仍然即時猜測按鈕正在減慢幀速率 – rtpenick 2014-10-19 02:10:51
