为什么 pygame.sprite 在我的班级中导致“最大递归深度”？

Question

I made this simple class and for some reason it crashes python and I dont know why

This is the code

import pygame
pygame.init()
class Entity(pygame.sprite.Sprite()):
    def __init__(self, pos, size):
        super().__init__()

and this is the error I get

pygame 1.9.6

    if hasattr(group, '_spritegroup'):
RecursionError: maximum recursion depth exceeded while calling a Python object

How can I correct this error?

pygame.sprite.Sprite() creates an object. For the base class, you only need to specify the name of the class. See Inheritance .

Change pygame.sprite.Sprite() to pygame.sprite.Sprite

class Entity(pygame.sprite.Sprite()):

class Entity(pygame.sprite.Sprite):
