I was thinking of making my own crosshairs for FA, but I'm not sure what size the sprite for each crosshair should be. Do they HAVE to be a certain size for them to work or does it not matter?

any size is fine, make it a square though.

 

create it in indexalpha

Yeah, I found a comprehensible tutorial on it here and made a fairly nice one. I can aim with it better than the ones Delta made( no offense delta, your crosshair set is freaking awsome). Its just a simple T crosshair that fades on the outer points of the T.

Any size wont work. If you use the default 64x64 pixel size used for the normal xhair for a scope, your reticle will be in the upper left hand corner of the scope. 64x64 pixels for the standard running around xhair, for scopes 256x256 is what you wanna use.

Yeah, right now I simply use the default scope sprites. I'll eventually get around to making a scope xhair. But I made my "running around xhair" 32x32 and it works fine.
