Question

我的玩家通过向敌人投掷武器进行攻击。当前，这是通过使用抛出的奇异剑来完成的，然后将其传送回玩家以再次抛出。我要更改此设置，以便有一个名为剑的类，当玩家想要扔出武器时可以调用该类。但是，我不知道如何在精灵组之间进行碰撞。这是我的碰撞当前工作方式的一个示例（只显示整个敌人的等级更容易）

class Bat(pygame.sprite.Sprite):
    def __init__(self, bat_x, bat_y, bat_image, bat_health, bat_immune, const, dash_counter, dash, dash_time, fly_count, fly_time): #There is an indent in the actual code, but stack overflow removed it in copying and pasting
        pygame.sprite.Sprite.__init__(self)
        self.bat_health = bat_health
        self.bat_immune = bat_immune
        self.const = const
        self.dash_counter = dash_counter
        self.dash = dash
        self.dash_time = dash_time
        self.fly_count = fly_count
        self.fly_time = fly_time
        self.image = bat_image
        self.rect = self.image.get_rect()
        self.mask = pygame.mask.from_surface(self.image)
        self.rect.topleft = (bat_x, bat_y)
        self.bat_x = bat_x

    def fly(self):

            if self.fly_count == 1:
                if pygame.time.get_ticks() - self.fly_time > 600:

                    if pygame.time.get_ticks() - self.fly_time > 1200:

        offsetP2B = (int(x - self.bat_x), int(y - self.bat_y)) #Player to Bat

                    immune_time = pygame.time.get_ticks()

        self.fly()  

    all_bats = pygame.sprite.Group()

这很完美，但是我希望我的武器像敌人一样，一个精灵组，这样我可以一次在屏幕上显示多个，但是我该怎么做呢？老实说，我不知道如何解决这个问题！

Answer 1

我相信pygame.sprite。groupcollide()是您要找的东西吗？ “找到在两个组之间碰撞的所有精灵。”

如果您想一次通过一把剑，也可以使用pygame.sprite。spritecollideany()。

两个精灵组之间的蒙版碰撞
