如何在没有spritsheets的情况下制作行走角色 - Python与Pygame

Question

我想在不使用精灵表的情况下改变它移动的方向时让我的角色改变精灵。我没有使用精灵表的原因是因为它似乎不适用于我想要做的事情。

pygame.init()

green = (0,200,0)
blue = (0,0,255)
titlebrownic = (77, 51, 43)
titlebrownac = (128, 85, 70)

#Player Sprites
PlayerStandRight = pygame.image.load('Resources/PlayerStandRight.png')
