Question

我用pygame，太空侵略者制作游戏，现在我正在做一些关于射击的玩家和玩家之间的碰撞（那些是图像），但是它不起作用所有的时间，我想知道为什么，以及解决方案是什么。谢谢你的关注！这是代码：

这是一个碰撞检测代码，可以检测一个矩形是否与另一个矩形碰撞，如果敌人的射击击中了玩家：

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:

它的工作原理是检测子弹的任何边缘是否接触到角色的任何边缘。我希望这会有所帮助。

碰撞不工作Pygame
