definequote 128		  SWITCHED FIRE MODE

This code seems to function correctly, however there is no way to see which fire-mode is currently selected without firing the weapon. Ideally, I would like to change the weapon texture depending on current selection, or change the ammo symbol. If that isn't possible, I could have a simple HUD addition in a corner somewhere showing which is selected.

I'm already confident in adding new textures to the ART files, but I can't find a way to swap out textures on screen (weapon texture & ammo symbol).

I'd love to hear any general suggestions for improvements or additions I can make too.

You could make right-mouse shoot altfire and left-mouse shoot regular fire, then there's no need switch modes. EDuke32 supports this.

I have bad news for you. You can't just "swap out" textures on screen.

Any different tiles appearing on the HUD from the hardcoded ones requires that you have your own HUD code that pretty much redraws the relevant parts of the HUD from scratch. You can try copying from another mod that does this and then changing them to your own tile numbers, but its still going to require tweaking to fit what you want to do, and judging from your post you have zero knowledge in that area.

EDuke32 downloads do come with a CON file written by Hendricks266 (at least I think its still included) that completely replicates all the hardcoded HUD stuff. If you start with that, it can make the job easier.

Realising now this will probably work a lot better than what I had in mind lol :/. For context, I was originally going for something similar to swapping out attachments in DOOM Eternal, but I think I'll just make it more akin to the way altfire works in Blood.

Thanks for all your help!

player[].weapon_pos should also be 0 before you allow the firing sequence to begin, and the player should be alive
