Re: [pygame] Scaling the hitbox/rect of a sprite

[Jeffrey Kleykamp <jeffrey.kleykamp@xxxxxxxxx>]

Oops, my code was wrong, it should be,

my_collide_rect = lambda a, b: a.hitbox.colliderect(b.hitbox)

You want to use the colliderect function of the Rect module to test if they collide.

Thanks for the help everybody, but it still doesn't work.

I've tried these functions as collided values (as Jeffrey Kleykamp
suggested):

pygame.sprite.collide_rect() takes only sprites as values and then uses
their rects. That means I can't use the sprite's scaled "hitbox" attribute,
otherwise I get this error: AttributeError: 'pygame.Rect' object has no
attribute 'rect'
And if I do sprite.rect = sprite.hitbox, the image gets blitted at the top
left corner again.

pygame.Rect.colliderect() doesn't work.

pygame.sprite.collide_rect_ratio() works as intended but causes a huge
performance drop, so it's not useable for me. I have quite a lot of sprites
on the screen (sometimes over 100).

Christopher Night is right. It would be a lot easier for me, if Pygame
sprites had an additional (optional) hitbox rect.

Maybe I should rewrite my collision detection passage and just use
pygame.Rect.colliderect() instead of pygame.sprite.spritecollide().
