I'm an artist trying to set up a demo to attract some attention to my game.
I spent 3 months animating the hell out of sprites. But here's the thing, I can't get rid of the background. I tried making it solid white but it only recieved part as transparent leaving a aura of white around the character. I tried it with several colors but it just seems to be acting bizarre. Somtimes not doing anything at all.
This is driving me nuts, so I would be happy if someone could explain it.

The transparent area needs to be solid; use *exactly* the same color everywhere. You can use the "fill" tool with slightly increased tolerance to fill the transparent parts of the image. Also, using white probably isn't the best idea - the default transparent color is pink, RGB(255, 0, 255), because it's unlikely the actual graphics will use this color anywhere.

But if your sprites have antialiased edges the preferred way is using an alpha channel. The alpha channel will help you to control the transparency of every single pixel of your image.
What method of creating sprites are you using?

I'm using photoshop and I tried it in white, blue, and the default 255,0,255 pink and it was solid using the paint bucket in photoshop. But I just now figured out the color changed in certain areas. It's a photoshop problem I guess. Thanks for your help

It changed? Umm... are you maybe using JPGs?

As far as I know there is not a bug in photoshop that slightly change colors. If there was such thing I'd be in serious trouble with my work
Anyway, the only two reasons I can think now is that you either used jpeg (as Jerrot already said) or a custom reduced pallete (did you use the save for web feature of photoshop?).

[artsyguy]

Yes I used jpg and no I didn't use save for web. I thought it took that file type

So bottom line is that you can't use jpg since it's cosine transformation of original image wich means that it will never get
you expected results. I would recommend using png since it's the best option for you. :-)

Thanks I'll try that.
