Hey there Hrk. I am a beginner scripter myself, i put a little code together you might find useful. 

---------------------------
-- Visz (Client)
---------------------------

function viszFunc()
	
	toggleControl("next_weapon", false )
	toggleControl("previous_weapon", false )
	toggleControl("vehicle_fire", false)
	toggleControl("vehicle_secondary_fire", false)

	setPedFrozen(localPlayer, true ) 
	outputChatBox("viszlek he")
end
addEvent("visz", true)
addEventHandler("visz", localPlayer, viszFunc)

function cleanUP()
	toggleControl("next_weapon", true )
	toggleControl("previous_weapon", true )
	toggleControl("vehicle_fire", true)
	toggleControl("vehicle_secondary_fire", true) 
	setPedFrozen(localPlayer, false ) 
end
addEventHandler("onClientResourceStart", resourceRoot, cleanUP)

---------------------------
-- Visz (Server)
---------------------------

function viszCommand(playerSource, commandName)

	triggerClientEvent(playerSource, "visz", playerSource)
end
addCommandHandler("visz", viszCommand)
