How do I make a rectangular sprite stop when it collides with another rectangular sprite using pygame?

Question

I'm trying to create some obstacles for the player in my program. I can't figure out how to make the sprite stop when it comes in contact with it from all sides.

I tried to use pygame.sprite.collide_rect and pygame.sprite.spritecollide , but couldn't figure out how to do it.

If you could just try to explain the concept, I'd rather try to figure the rest out myself. Thanks in advance!

Answer 1

def move_rect():
    new_pos = player_rect.pos
    new_pos = new_pos[0]+dx,new_pos[1]+dy
    new_rect = rect(new_pos,player_rect.size)
    for enemy in enemy_rects:
        if new_rect.colliderect(enemy):
           dx,dy=dx*-1,dy*-1 #reverse direction to "bounce"
           #alternatively you could just return here probably

    player_rect.move(dx,dy) #do the move, no collisions

something like that at least ... (I doubt it will work, its more to give you the concept)
