报错：
发生异常: TypeError
'pygame.Surface' object is not callableline
26, in player_mini_img = pygame.transform.scale(player_img(25,20))
我去代码里寻找了pygame.Surface,可无结果
我想要的效果是能运行且无报错
pygame.transform.scale(player_img(25,20))你本意是： pygame.transform.scale(player_img,(25,20)) 才对吧！
pygame.transform.scale(player_img(25,20))改为pygame.transform.scale(player_img,(25,20))
