python - 尝试绘制角色时Pygame蛇游戏属性错误

问题描述

第 134 行我收到一个属性错误，我对 pygame 还很陌生，所以我相信这与我的论点有关，但我不确定。这是错误所在的行：

pygame.draw.rect(window.pygame.Color("RED"), pygame.Rect(int(foodpos[0]), int(foodpos[1]), 10, 10))

确切的错误是：

AttributeError: 'pygame.Surface' object has no attribute 'pygame'.

Traceback (most recent call last):
