python - How do I make a sprite "stand' on another sprite in pygame?

Question

I've got two sprites that can detect collisions, but I'm not sure how I can make my character sprite "stand" on my platform. Nothing I've done seems to work.

Answer 1

If you have 2 pygame.Rect objects, you can move the 2nd rectangle on the 1st rectangle by setting the bottom of the 2nd rectangle with the top of the 1st rectangle. With the virtual attributes of pygame.Rect it is easy to do so:

rect2.bottom = rect1.top

Or if you have 2 pygame.sprite.Sprite objects:

sprite2.rect.bottom = sprote1.rect.top

If you have 2 pygame.Surface objects (surf1 and surf2) and the 2 corresponding positions (x1, y1) and (x2, y2), use get_rect() to create pygame.Rect objects from the Surfaces. Move the 2nd rectangle on the 1st rectangle and update the position of the 2nd rectangle:

rect1 = surf1.get_rect(topleft = (x1, y1))
rect2 = surf2.get_rect(topleft = (x2, y2))

rect2.bottom = rect1.top
y2 = rect2.y
