Python 敌方.rect不更新

我一直在做关于坦克的项目（类似于坦克故障），我有一个bug。让我解释一下

当敌人产卵，我向它射击时，碰撞就起作用了。但只要我移动敌人并再次向其射击，碰撞就不算了。我认为

敌军（）

类中的

self.rect

有问题

另外，

如果self.rect.collide rect（敌方.rect）：

应该使用

敌方.pos

参数，但是

敌方.pos

必须是rect样式的对象

任何帮助都将不胜感激

在检查子弹是否与敌人的实例发生碰撞之前，您正在Bullet的更新功能中创建敌人的实例。这意味着您总是在默认位置生成一个敌人，并且只检查与该敌人的碰撞

你应该做的是检查子弹是否与任何已经存在的敌人相撞。有很多方法可以做到这一点。您可以将敌人列表传递到Bullet的构造函数中，您可以使用全局变量，您可以使用getter函数

class Bullet(pygame.sprite.Sprite):
    ...
    def update(self):
        ...
        enemy_list = #Get all enemies here somehow
        for enemy in enemy_list:
            if self.rect.colliderect(enemy.rect):
                self.lives -= 2
                if self.lives <= 0:
                    return self.kill()
                bounce.play()
