Difference between get_rect() and get_AABB() for Sprite

[che...@sina.com]

I have checked the online document for Sprite introduction, but still confused about the two functions difference.

So, could someone explain to me the detailed differences for them?

Thank you so much.

get_rect does not handle sprite rotations, get_AABB accounts for rotations.

Examples:

    test\test_rect.py

    test\test_sprite_aabb.py

Thanks Canepa.

 

But seems get_rect() doesn’t work well when image_anchor is not (0, 0), that’s why?

I don't know for sure, guess one of the following

   - make get_rect more lightweight by sticking to a simpler case

  -  anchor considerations were overlooked when get_rect was coded

I would use get_AABB
