So. for my request i'd like a gun or a pack of guns whatever you like to do.
This would seem hardcore as I can't do any LUA yet.

A gun that if you lost a leg or something the accuracy will lower so the bullets will have less chance of hitting the enemy. So if you're at 50 health and lets say you have 1 leg missing, the enemy would have a chance to kill you, at first that doesn't sound very nice. But lets say the enemy has a leg missing while he is using the gun, it wouldn't be fair for him.

So would this be possible at all?

Side note: Another idea adding to this gun is you know how the coalition have a helmet?. Well armor attachables would be recognized by the script and change the weapons accuracy accordingly.

TL:DR Version
A gun that changes accuracy depending on the actors health and limbs and if possible armor attachables.

I'm pretty sure you can't change ShakeRange with Lua.

How on earth would you run that script either?

Damn. Ah well, I tried.

At 1 health, up to half a radian of spread is added. At 100, nothing happens.

If you want to make the effect greater, decrease the 200.
Eg, 100 would cause up to 1 radian of spread.
And vise versa, eg, 400 would cause up to 1/4 radian of spread.

It would be possible to change this so it wouldn't mess up the muzzle flash, but that would be a little more complicated.

Bits of code were taken for this from Abdul's recoil demo.

Have the gun spawn a dedicated actor positioned at (0,0), pinned and non-colliding that calls thing:Update() on all MOs that have a parent MO (check MOID against RootMOID) or some such workaround.
