我需要帮助来改进我的Tron简单游戏。我首先为一个项目创建了Snake，然后决定创建它，因为我认为它会有点相似。然而，即使我在两者中使用了几乎相同的密钥适配器代码，但Snron的作品却没有。但是Tron并没有这样做。如果它有所不同，Snake在Eclipse中编写了JGrasp和Tron。根据我从调试中可以看出的情况，密钥适配器根本没有响应，这使得我认为这是一个焦点问题，但是Tron的代码请求集中在Snake所做的所有相同的时间，并且正如我所说Snake正常工作。如果有人可以帮助我，那就太好了。
另外，因为我对编码比较陌生，所以后来我会喜欢关于如何提高程序速度或减少内存的建议。此外，你对我应该添加到游戏中的功能的任何建议或我可以使游戏看起来更好的方式，我将非常感谢听到他们。我可能需要帮助制作这些功能，特别是如果他们引入了新概念，那么我可能会在事后寻求帮助以便如何做些事情。
无论如何这里是代码：
