Pygame 问题：我的播放器图像不随滚动而移动

Question

Firts I am french so excuse-me for my english. I have recently discoverd pygame and I love that so decided to create a rpg on pygame and... I have a little problem: with many, many difficulty I made a scrolling system on my pygame's rpg I evn do a system how make sure player's image gets back when he go up, puts himself in profile... BUT (a big but) my player's image don't move, the scrolling, move and the player's rect also, I don't know I can solve that so please help me.:!!! The main.py file :

from game import Game
from level import *
pygame.init()

lvl = Level()
screen = pygame.display.set_mode((1024, 768))
pygame.display.set_caption("RPG") 
game = Game()
cam = Camera(1024, 768)
running = True
lvl.generer()
print(game.player.rect)
clock = pygame.time.Clock()

while running:
    cam.update(game.player)
    #print(cam.rect.topleft)
    if game.pressed.get(pygame.K_RIGHT) and game.player.rect.x + game.player.rect.width < 1080:
        game.player.move_right()
        lvl.afficher(screen, 0, 0, cam.x, cam.y)
        #print(game.player.rect.x)

    elif game.pressed.get(pygame.K_LEFT) and game.player.rect.x > 0:
        game.player.move_left()
        lvl.afficher(screen, 0, 0, cam.x, cam.y)
        #print(game.player.rect.x)

    elif game.pressed.get(pygame.K_DOWN):
        game.player.move_down()
        lvl.afficher(screen, 0, 0, cam.x, cam.y)
        #screen.scroll(0, -game.player.velocity)
        #print(game.player.rect.y)

    elif game.pressed.get(pygame.K_UP):
        game.player.move_up()
        lvl.afficher(screen, 0, 0, cam.x, cam.y)
        #screen.scroll(0, game.player.velocity)
        #print(game.player.rect.y)

    #print(cam.rect.x, cam.rect.y)
    #print(cam.rect)

    screen.blit(game.player.image, game.player.rect)
    print(game.player.rect)

    pygame.display.flip()

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = False
            pygame.quit()

        elif event.type == pygame.KEYDOWN:
             game.pressed[event.key] = True

        elif event.type == pygame.KEYUP:
            game.pressed[event.key] = False```

                num_case += 1
            num_ligne += 1```

Answer 1

Ok I just found the solution but It's making an other problem I'll ask the question on a other post. At x = num_case * tailleSprite - camLeftX and y = num_ligne * tailleSprite - camLeftY on level.py just replace the - by a +
