碰撞不起作用Pygam

Question

我正在用pygame，太空入侵者做一个游戏，现在我正在做eneimies的拍摄和玩家之间的碰撞（那些是图像），但是它不是一直都有效，我想知道为什么，以及解决方法是什么。 感谢关注！ 代码如下：

这是一个碰撞检测代码，如果一个矩形与另一个矩形发生碰撞，如果敌人的子弹击中了玩家，它会检测到：

if player x < shot x + player width and player x + shot width > shot x and player y < shot y + player height and shot height + player_y > shot y:

它通过感应子弹的任何边缘是否接触到角色的任何边缘来工作。我希望这有帮助。你知道吗
