Btw, heres a few tip.
Firstly,only those who edited their system.mrs would be able to deal damage to him, for example, i set my he gren to 10000 damage and 2000 he grenades, no delay.When i go public server,it doesnt damage the players,but causes good lag =) But when i uses it on a guy who have also edited his system.mrs, he would take the damage and stuff.Same as range.I set my dagger range to 100.Seems to damage those who edited system.mrs file only. btw, editing damage and ammo does not work.Once u go beyond your guns original bullet limit, the shots will not register.Heard your bullet have to be less than a certain amount to work.But still it doesnt.
