Title: Sprite "smearing"?
Post by: N1ghtly on February 22, 2012, 09:42:03 am

I was working on my stats screen for my game, just prototyping it but when I draw certain sprites it looks like they're "smeared" a bit.

Any ideas?

Could you elaborate on what "smeared" means? :D

Haha I guess it's a word I made up :P
Look at the + and - circle for example :)

Looks like bad alpha around borders in the original image.

That's not it because in-game they work perfectly :/

What's the difference between the menu and the game?

Maybe it's because the background is different, it shows more on black.

It can't be the sprites themselves, they're crisp and clean. :(

Have you tried to disable smoothing (image.SetSmooth(false))?

I thought it was disabled on default?

By default it is disabled in SFML 2, but enabled in SFML 1.6.

I'm using SFML 2 so it's disabled :)

Can you write a complete and minimal code that reproduces the problem, so that I can test it?

I was able to fix the problem :)
I used one temporary sprite to load them all into a vector and I forgot to pass true to the SetTexture function each time (to reset the drawing rect).
