Pygame TypeError surface

Bonjour, je suis en python et je ne comprend pas pour quoi mon self.screen ne marche pas ?
L'image que vous voyez en dessous représente l'érreur, et les pages de code en dessous, tous mon code.
Le problème agis lorsque je lance le programme.


main.py

import pygame

from game import Game

if __name__ == '__main__':
    pygame.init()
    game = Game()
    game.run()

        # frst fenêtre
        self.screen = pygame.display.set_mode((500, 500))
        pygame.display.set_caption("LumberTown")

        # charger la carte
        tmx_data = pytmx.util_pygame.load_pygame('lumbertown/map/carte.tmx')
        map_data = pyscroll.data.TiledMapData(tmx_data)
        map_layer = pyscroll.orthographic.BufferedRenderer(map_data, self.screen.get_size())
        map_layer.zoom = 2

        # genérer le joueur
        player_position = tmx_data.get_object_by_name('player')
        self.player = Player(player_position.x, player_position.y)

        # dessiner le groupe de camque.
        self.group = pyscroll.PyscrollGroup(map_layer=map_layer, default_layer=3)
        self.group.add(self.player)

voici les erreurs qui son print :
