I'm making a platformer game where the player has to go to the next level and he will face tasks and challenges. I made it so that when it collides with the gem it will print "collision", that all worked fine but the player rectangle was too big and I tried using pygame.Rect() instead of pygame.get_rect(). The reason is because of the transparent background and now I can't get the rectangle to be smaller.
