platformer problem

[abscorpy]

im trying to make a platformer


but it doesnt work properly

first of all, what it should do is that the man should face right or left after pressing left or right arrow, then it should fire some projectiles when you press space bar, thanks for the support

pygame.quit()

anyone can help?

Move keys = pygame.key.get_pressed() to just after the event loop
It must refresh every loop.

    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            run = False
    keys = pygame.key.get_pressed()

You can also do this.

for event in pygame.event.get():
    if event.type == pygame.QUIT:
        run = False
    elif event.type == pygame.KEYDOWN:
        if event.key == pygame.K_SPACE:
            # action
