Well. im trying to make a weapon mod, and a actor mod, didnt get troubles with the actor but.... how can i do to customize the weapon's damage? i've been able to make a lot of things on the weapon, making the bullets go faster, penetrate more or less, add more recoil, go slower but... didnt get how to modify the damage amount, can you help me over there?

you have to make more or less particles come out of the gun, because damage is set by the wounds, not by the bullet.

If you increase the penetration (vel*mass*sharpness) you can make it penetrate targets completely and leave exit wounds.
If you increase the impact force (vel*mass), you can knock features off target. The Ronin Peacemaker is a perfect example of this.

Other than those, yeah, you want more particles. If you want it to look like one bullet, give the gun 0 particle spread. Or if you want to keep some inaccuracy, make it shoot an emitter with some inaccuracy, and then the emitter shoots your particles with 0 emission spread. It's a bit more complex, but you can do a lot of neat stuff when you shoot emitters that shoot your projectiles.

Thanks a lot guy. Ill try it and then I will post something

Ah, I feel like this is an obvious one, but how does one reduce range?

Lifetime in MS * Velocity of your particle (in supposed meters/second) = range of your bullet.

AirResistance will also be helpful to make your weapon's damage reduce with distance.

Lifetime in MS?

The lifetime of the particle (in this case, a MOPixel). It is defined in Milliseconds.

On a similar note to this, how would one increase an actor's overall durability? For example, boss characters like the mega crab?

Just increase the GibWoundLimit if you want it to resist a bigger number of bullets, or the GibImpulseLimit to make it resist mass-based projectiles. Changing the actor's material to one with higher StructuralIntegrity will also make it deflect lower caliber ammo.

Well, in looking at the Mega Crab's .ini file I noticed there's no GibWoundLimit defined for its body, and in the actual mission I'm just rattling bullets into him with an assault rifle and his life takes quite some time to get to zero.

I'm not exactly trying to make the limbs last longer as much as I am the actual actor.

EDIT: Never mind, problem is solved.
