		triggerEvent("onClientVehicleWeaponFire", getLocalPlayer(), vehicleFireType, vehModel)
	end
end
bindKey("vehicle_fire", "down", vehicleWeaponFire, "primary")

function vehicleWeaponFire(thePresser, key, keyState, vehicleFireType)
	local vehModel = getElementModel(getPedOccupiedVehicle(thePresser))
	if (armedVehicles[vehModel]) then
		triggerEvent("onVehicleWeaponFire", thePresser, vehicleFireType, vehModel)
	end
end
 
function bindOnJoin()
	bindKey(source, "vehicle_fire", "down", vehicleWeaponFire, "primary")

	outputChatBox(getPlayerName(source).." fired his "..getVehicleNameFromModel(theModel).."'s weapon ("..typeOfFire..")")
end
addEvent("onClientVehicleWeaponFire", false)
addEventHandler("onClientVehicleWeaponFire", getLocalPlayer(), eventVehicleFire)

function eventVehicleFire(typeOfFire, theModel)
	outputChatBox(getPlayerName(source).." fired his "..getVehicleNameFromModel(theModel).."'s weapon ("..typeOfFire..")", root, 0, 255, 0)
end
addEvent("onVehicleWeaponFire", false)
addEventHandler("onVehicleWeaponFire", root, eventVehicleFire)
