所以我花了大约3个小时试图围绕如何制作“键绑定”并将其应用于我开发的游戏。其中一些至少有点意义，而其余部分超过我的头脑。
这可能只是我设置游戏的方式，这使得无法使用“键绑定”但我不知道。
我查看过这些帖子及其提供的链接，试图了解它们，但仍然不知道哪里可以开始。
How do I move a graphic across the screen with arrow keys?
How to make an image move while listening to a keypress in Java.
addKeyListener() doesn't work for JPanel
KeyListener, keyPressed versus keyTyped
How to use Key Bindings instead of Key Listeners
这是我的WIP游戏的一个工作示例，除了用于移动玩家的键绑定之外的所有内容（左上角的红点）。

我不希望听起来像是一个想要为我完成编码的人，我需要的只是我需要完成目标的过程类型的一个例子。
请记住，我是一名仍在学习的新手程序员，对任何不被视为“基本”的代码的解释将不胜感激：）
