【问题描述】：
我几乎已经完成了一场带有迷宫墙的决斗坦克游戏，尽管有一个 bug 已经困扰了我很长一段时间。通常，用户能够将他们的坦克放置在其中一个迷宫墙的长边的尖端并完全穿过墙，这使得展示非常尴尬。一般来说，使用 pygame 的 .collidepoint 函数的碰撞检测是有效的，但再一次，不是在边缘和顶点周围。例如，当坦克开始从墙的长边顶部移动时，这个 bug 就会出现：
我尝试在.collidepoint 函数的参数中使用各种and 语句，认为它可能只是检查一个坐标，尽管这显然也没有帮助。有谁知道导致这种情况发生的原因以及需要什么代码来确保在边缘周围正确检测到碰撞？这是我一直在尝试的：
