Hey there! Been playing for a while but haven't used the forum before, so work with me here. I play with a couple of friends and they keep asking me to make a melee-only mode. Fair warning, I have little to no experience with the programming aspect of this, but I'm here to ask if it's possible to:
- Black/whitelist only certain weapons (base game and modded) when randomized
- Change the player's starting weapon
- (Optionally) Toggle said mode with a variable

If this is possible, any help with this would be appreciated!

Hello! Sorry for the long delay in replying.

A while ago, I made a mod that could ban weapons from the game. However, it's not built to remove entire categories of weapons, and the randomizer system in general is built to be category-based. It is unfortunately not built to do the whole "every weapon token is a melee weapon" thing.
In case you want to mess with the weapon ban mod, you can find the latest version here and its documentation here.
Warning there: weapon remover mod is not the latest version of that module, as I rolled it into the miscfixes mod because server hosts would often host it together with miscfixes.

To do precisely what you want here, though. You would need to make a mod that taps into some of the more annoying systems to mess with in the game.
I could probably put something together, but you'll have to wait at least another day or so.
