我最近添加了代码：
if enemy.rect.colliderect(player.rect):
到我的程序，它会导致所有敌人精灵在游戏加载时冻结，而不是当他们触摸玩家精灵时，我不知道为什么这样做以及任何阻止它并使其正常工作的方法（非常感谢，只有当被另一个精灵接触时停止，我可以提供xml和json文件，但我怀疑它们会不会。
先谢谢。
答案 0 :(得分：1)
如果碰撞检测出现问题，请打印所有相关对象的部分。如果你这样做，你很快就会发现所有的位置都在同一个位置（0,0），因此它们会在游戏开始后立即发生碰撞。
您必须在班级中设置rects的位置：
self.rect.topleft = (self.x, self.y)
# Or
self.rect.x = self.x
self.rect.y = self.y
# Or
self.rect = self.sprite.get_rect(topleft=(self.x, self.y))
您还可以使用self.rect.center或其他属性。
另外，不要忘记在主循环中移动物体的部分，否则它们将保持在相同的起始位置。在您的情况下，您只需将topleft设置为enemy.x和.y（或者只删除x和y属性并直接更新rect.x和rect.y） ：
enemy.rect.topleft = (enemy.x, enemy.y)
