使用 Pyglet 和移动设置 window 的分辨率
Setting resolution for a window using Pyglet and moving
我是在 python 中使用 Pyglet 的新手，我的代码有一些问题。首先，我不知道为什么设置分辨率不起作用。其次，当我尝试移动 "snake" 时，它什么也没做。感谢任何帮助。

以下是解决这两个问题的方法。
第一个问题是宽度和高度是在创建 window 时定义的（之后可能还有一些方法可以更改它，我还没有费心学习）。
第二个问题是您更新 self.c，例如 self.snake_head.x 的副本。因此，当您认为自己正在更新 self.snake_head 的 .x 时，您实际上是在更新副本，仅此而已。
上面的代码解决了这个问题。它并不完美，例如 - 按键不会 trigger/update 直到给定的时间间隔。但这些是您在这个问题之后可能正在处理的事情。
