我几乎已经完成了这个Flash游戏，但是当我测试它时游戏会加速减速。我一遍又一遍地阅读剧本。试图从脚本中评论部分，但它仍然会减慢速度。
这是我的整个剧本：

如果您有一些优化提示或甚至在我的代码中发现错误，请发表评论。提前致谢！ :)
答案 0 :(得分：3)
我无法确切地说，你的代码很长，但你是在ENTER_FRAME的事件监听器中为ENTER_FRAME添加一个事件监听器到一个在每次迭代时重新定义的函数吗？ / p>
如果是这样的话：
ctrl_birdie（将其放在与其他方法相同的级别），addEventListener(Event.ENTER_FRAME,ctrl_birdie)一次如果它无法解决您的内存泄漏问题，至少会使您的代码更容易阅读。
