Alright, I have correctly created a weapon, yet with wee bit of an issue, I can't figure out on how to get it to the color I want it to be in the game.

In other words, palette problems that I do not understand.

Vwoop. There are other tutorials, theoretically, in this topic here, but the only one I know still works is the one I made, seeing as the images are hosted on my tinypic account.

Thanks Duh, but I has another problem, how do I paint the other side of the gun whenever I face to the left?

That would be some Lua trickery, not sure exactly what you'd need.
Something to the effect of two frames for your gun, and a Lua script on the gun that changes to the second frame when your actor is facing left.

never mind, solved problem. Thanks for the help.

P.S. That Gimp stuff really works.
