LWJGL 2D Tile游戏每秒使用超过50 MB的RAM

时间：2015-03-26 01:20:26

标签： java 2d lwjgl tile

所以我是一个相对较新的编程，我正在尝试使用LWJGL制作2D游戏。我使用数组列表中的tile创建了一个背景图，然后我更新了必要的东西，比如播放器等，然后我将它们绘制到屏幕上，然后更新屏幕。我已经看到其他人这样做很好，但每当我这样做时，它每秒消耗几乎100 MB的RAM，导致我的计算机在游戏运行30秒或更短时间内冻结。我不确定是否是导致此内存使用的图形或其他内容，我已经检查过以确保在没有我知道的情况下没有运行代码，如果有人应该告诉我哪些错误会很好。我已经提供了我的游戏中使用的主要类，总共大约10个，但我只显示了3个，因为我认为它足以说明我的观点。我知道有些代码可能看起来好多了，但就像我说的那样，我对这一切都是新手。谢谢！
