It's a vibration addon for your server, it's an addon because it's good for binding to other script. Ok let's tell what this is about. Vibration, it likes a real shoot, when you shoot you fell a vibration, cause of the shake command. There is a specific vibration of the type of weapon, Pistols, Shotguns, Automatics, Rifles, Snipers, Machine Guns, Laser, Flamethrower, RPG, Launchers, Melee. You can change the value of the Vibration. How? Just find in the script the value that you want to change and edit it, Example : Pistols = 4 (Pistols, type of weapons that will make that power of shake, 4 = The power of shake)
