Question

有人请告诉我如何让子弹类/变量工作，因为我总是得到错误“'子弹'对象不可调用”。

继承人的子弹课程

class Bullet(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()

        self.image = pygame.Surface([3,3])
        self.image.fill(brown)
        self.rect = self.image.get_rect()
        self.rect.center = Body.rect.center
        self.tick = True
        self.tickNum = 0
        self.tickTarget = 10

    def update(self):
        if self.tickNum == self.tickTarget:
            self.tick = True
        else:
            self.tickNum += 1

        self.velX = mouseX/20
        self.velY = mouseY/20

        self.rect.x += self.velX
        self.rect.y += self.velY

继续称呼它并使其射击

while True:
    if buttonDown:
        Bullet = Bullet()

        if Bullet.tick == True:            
            bullet_list.add(Bullet)
            all_sprites_list.add(Bullet)
            Bullet.tick = False

Bullet = Bullet()是你的问题。你正在为命名空间做些讨厌的事情。相反，请执行bullet = Bullet()或b = Bullet()
