I am editing the weapons configiration file and cannot find the option for rang.

any help? thanks.

SharpRange = (your number here)

to clarify, "sharprange" is how far you can zoom the weapon.
If you're looking to change the range of the projectiles, it's a combination of firevelocity and lifetime for simple projectiles, AFAIK.

Adding on to Dr. Evil's post, the above plus GlobalAccScalar, which affects how much the projectile feels gravity, and AirResistance, which as you would expect controls how much the projectile is affected by air resistance.

thanks
