*之后的Add()参数必须是可迭代的,而不是int Pygame

你好,我是pygame的新手,我正在尝试编写shmup游戏。 但是我总是遇到这个错误:

  

TypeError:*之后的add()参数必须是可迭代的,而不是int   self.add(* group)

这是错误的回溯:

  

文件“ C:/Users/Pygame/game.py”,第195行,位于       player.shoot()

     

文件“ C:/Users/Pygame/game.py”,第78行,正在拍摄中       bullet =项目符号(self.rect.center,self.angle)

     

“ strong:init ”中的文件“ C:/Users/Pygame/game.py”,第124行       超级(子弹,自我)。初始化(位置,角度)

这是我到目前为止编写的代码,它可以很好地工作,但是当用户想要拍摄时,就会引发错误。

有任何评论吗?

您要将posangle传递给__init__的{​​{1}}方法,

pygame.sprite.Sprite

,但是您只能传递将添加此精灵实例的精灵组。因此,只需删除这些参数即可:

super(Bullets,self).__init__(pos,angle)
