Broken in what way ? I downloaded the game, installed this mod and tested, it works fine my end, I'm sure there's some kind of issue your end but there's not much I can do to help the only info you give is "Broken".
Might be something related to the games recent update

Broken atm

I'm gonna assume its the custom line trace function you're eyeing out, I considered making a function lib mod but never got to it, ofcourse you can zoink some code no problem :)
Msg me if you questions, unrelated ones too ;)

Hey, I am currently in the process of making a 40k bolter mod, would it be ok if I Frankenstein some of your code into that project?

no me funciona, alguien tendrá idea de porque?

I'm gonna update soon, I fixed both issues so it no longer collides on water and friendly factions turn hostile. If yall(specifically Asskal) are unhappy with any balance numbers such as value/weight/durability then tell me and ill update it too, also draw me a better texture and I'll use it :)

I think it would be nice to change the texture. Mismatch with the actual weapon is too much...

I'm aware of the crash and there's really not much I can do about it, I posted it in the modding discord and the devs already confirmed it will be fixed in the next game patch. There are mod conflicts due to a context error.
This mod will run fine either own its own or with my other mods, but will likely crash with other creators mods installed too

when i fire the game crashes

im getting error:script/item_spawner.script" mod "M32 Grenade Launcher how do i fix this

Diabolical :D
