Flash遊戲減速

Question

我幾乎完成了這個Flash遊戲，但是當我測試遊戲時，遊戲速度會加快。我一遍又一遍地讀了劇本。試圖從部分腳本中評論部分內容，但仍然變慢。

這是我的整個腳本：

如果你有一些優化建議，甚至找到我的代碼錯誤，請發表評論。提前致謝！ :)

Answer 1

我真的不知道，你的代碼是相當長的，但是你是否在ENTER_FRAME的事件偵聽器中爲ENTER_FRAME添加了一個事件偵聽器到一個在每次迭代中重新定義的函數？

如果是這樣的：

• 得到ctrl_birdie了監聽器（把它放在同一水平的其他方法），
• 呼叫addEventListener(Event.ENTER_FRAME,ctrl_birdie)只有一次，
• 刪除它，當你不需要它（如果你不再需要它）。

如果它不能解決你的內存泄漏，至少它會讓你的代碼更容易閱讀。
