我正在尝试制作一个游戏，其中有两个玩家互相射击。我的一位来自某班的球员成功地出现在屏幕上。但是第二个玩家来自另一个职业，实际上是另一个具有相同功能的职业的复制品。但以某种方式不起作用：

clock = pygame.time.Clock() # A clock to limit the frame rate.
pygame.display.set_caption("this game")

picture = pygame.image.load("C:/images/cliff.jpg").convert()
picture = pygame.transform.scale(picture, (1280, 720))

screen.blit(self.picture, (self.xpos, self.ypos))
