Transparent part of a sprite

[lorence30]

is the transparent part of a sprite is still collidable when i use globalbounds?

I have a sprite and I use gimp to make some part of sprite transparent.

No Yes. The global bounds of a sprite (or any other SFML entity) is only computed from its position, scale and size.

got it thanks, how about localbounds?

Wouldn't it be collidable for the transparent parts then? A sprite that is transparent due to its texture having transparency shouldn't mess with the global bounds.

Same.

Ok. I realize that I meant "Yes" in my previous answer. Thanks for correcting me

Okay thanks for the answers, I tried it just now and its clear thanks

Hey what your talking about is pixel perfect collision, the intersects function that SFML has built in would act at bounding box collision. I believe that SFML doesn't have pixel perfect collision built into it, I think I remember reading something similar to this before.

Hmm you probably could code it yourself, you have access to all the pixels of your sprite, I'm not sure how efficient it would be but could be a fun project for you I'm sure, teach you a lot more about the basics of collision detection.

I think there's something on the SFML Wiki about pixel-perfect collision, might be worth a look.
