I am making a very simple game where the bird (player) has to dodge the rock and if it gets hit by the rock you lose. I am trying to use pygame.sprite.collide_rect() to tell if
You have this:
col = pygame.sprite.collide_rect(sprite1, sprite2)
But an easier way to do this would be to simply use colliderect which is a function of rect. It might be easier to try this:
col=sprite1.rect.colliderect(sprite2.rect)
