我用pygame写超级马里奥时，图片加载错误，而python不报错

问题代码

from .. components import info,player

    def update(self,surface,keys):
        self.player.update(keys)
        self.update_player_position()
        self.update_game_window()
        self.draw(surface)
    def update_player_position(self):
        self.player.rect.x += self.player.x_vel

    def update_game_window(self):
        third = self.game_window.x + self.game_window.width / 3
        if self.player.x_vel > 0 and self.player.rect.centerx > third:
            self.game_window.x += self.player.x_vel
    def draw(self,surface):
        self.game_ground.blit(self.background,self.game_window,self.game_window)
        self.game_ground.blit(self.player.image,self.player.rect)
        surface.blit(self.game_ground, (0, 0), self.game_window)
        self.info.draw(surface)

from source import tools
from source.states import main_menu,load_screen,level
def main():
    state_dirc = {
        'main_menu':main_menu.MainMenu(),
        'load_screen':load_screen.LoadScreen(),
        'level1':level.Level1()
    }
    game = tools.Game(state_dirc,'main_menu')
    game.Run()
if __name__ == "__main__":
    main()

运行结果

我想要达到的结果*

检查图像绘制的顺序是否正确，后绘制的图像会遮盖先绘制的。

补充一下 这是tools.py

python
