I have NO idea where it is supposed to go in the .ini file.

Can someone please tell me?

There really isn't a value with says Recoil =.
Depends what you want as recoil, knockback? Spread?
Specify what you need.

Knockback recoil.

The higher the mass of your projectile, the more recoil, other factors include the Velocity of the projectile.

Basic thing to keep in mind: Mass x Speed = Force

So make a heavy round, make it fly out of the gun at a tremendous speed, and it's going to slam into something with the force of a Mac truck barreling off the express way.
But!
If you make a force go left, it's going to push off right as well. Like when you hit a baseball, there's a jarring feeling in your hands gripping the handle; this is the same amount of force going into your hands as what you hit the baseball with.
Twwig! You're getting off the damn topic! Alright, so in CC, the actor's stats also effect how it's affected by recoil. Take the big, heavy Brown Coat and a wimpy little Skeleton, then give them both a Peace Keeper pistol. A Brown Coat's a strapping young (possibly alien) lad, loads of muscle, lots of bulk. Firing off that revolver hardly budges the fat bastard. What about the Skeleton? Weighs as much as paper, his joints are held together with chewing gum, and he falls apart firing a gun with that much kick.

tl;dr: Big bullets that go very fast kick back very hard. Heavy actors with tough joints suffer less from the gun's kick.

...if any of this is utter garbage, give me a shout and I'll erase everything before any new folks take it to heart.

Nope, that's correct. The heavier the round, and the faster it goes, the more your actor is going to feel it. There are ways around this of course.

Note that recoil doesn't work like in real life, your actor's aim won't be kicked up, only back.

As a side note, if lua doesn't work with attachables from the get go in B24 I'll be dissapointed. I've always wanted to be able to do fun things with recoil etc.

I want this, i counld't use lua to pin an actor or gun in the scout of my technologies.

Also, crabs don't experience recoil, in case it ends up being pertinent.

Wait, what? This is very possible as of now, unless you're trying to do it in a fairly backwards manner. What was the context?

Remember the scout Technologies tank from the MC6? [Crab Contest]
I designed it to carry things, but i couldn't attach the script i use for my magnetiser
[mod dump bottom of first page] and apply it to an attachable which i attached to an ACrab.

if the attachable and the tank were always on the play field you could have quite easily done that. if you grab the attachable beforehand, you can still do attachable:update() or whatever. it just doesn't do it natively.

I'm sorry, but i did not get that, i'm not fluent with Lua, i editted that code from the rocket dock code.

Nevermind. Suffice to say it's possible now, but yes probably easier with proper attachable support in lua.
