爲什麼我的XNA遊戲滯後？

在我們保存代碼之前，代碼運行得非常好，並嘗試將其提交給我們的編程課程。我們相信我們有某種內存泄漏，但無法發現它。我們在保存代碼之前以及保存完好之前沒有對代碼進行任何更改，所以當我們保存它時出現了問題。以下是我們的更新方法中的所有代碼。我們有更新方法中每個困難的情況，這是我們認爲問題所在的地方。爲什麼我的XNA遊戲滯後？

縮短下來的代碼只有相關的部分請... – lifetimes

我不知道內存泄漏將在哪裏。我認爲這是其中一種情況。我們編輯了主要帖子，僅包含一個案例 –

您是指「保存」它是什麼意思？ –

您似乎在不斷地在每次更新蜱排隊的歌曲在您的MediaPlayer：

你會想要將這個您的更新之外（）方法

MediaPlayer.Play(BackgroundMusic);
