sprite jaggies

[Richard Rae]

Everytime I make a sprite it always shows up with "jaggy" edges.What format should images be used in so that I can get nice crisp,smooth sprites.
My game resolution is set to 800x600 and fullscreen.

       Thanks

24bit or 256 colors.
Sorry for delay in answering.

24 bit colours.If I use anti-aliasing when making the sprites in paintshop pro the effect is just terrible when the image is masked.If I make them with out anti-aliasing the effect is "jaggy" especially when making round sprites.Is there any way of using a black and white alpha mask.

OK. Painshop is the problem. Use "black" as background with paintshow - it mostly uses antialiasing all the time. Then, when done, load the image with MSPaint and "paint" the transparent pieces with that pink - it's in MSPaint's default palette.

HTH,
