I am working on a game and I needed to make collision detection. I decided to use the function pygame.Rect.colliderect(). However, it is giving me the error:
pygame 2.0.0.dev6 (SDL 2.0.10, python 3.7.2)

I don't see what is wrong here, as I believe this is how colliderect is used. I am really close to finishing this program, and any help is appreciated. Thanks.
