looking through the stock weapon and bullet sprites I noticed that some of them have alpha maps. can you create alpha maps for custom weapon/bullet sprites and how would you get them to work in game?

Those actually aren't used in the game. They're left over sprites from the hardcoded previous versions, placed here for reference.

Go ahead and move the stock weapon/bullet folders somewhere else, you'll see the game still runs without a problem.

didn't know that, but can you use alpha maps for custom sprites?

If you mean as bullets, yes, you can.
I do it anyway. Find it easier to colour.

it would be more useful with turrets for me especially for muzzle flash effects

The stock sprites distributed with the game are indeed just for reference and BSF stores its own internal versions in the exe, but alpha maps ARE used in the game internally.

I think hes asking whether you can use alpha maps to control transparency of sprites. The answer is no.
