Superjump (player) script

[Lalalu]

Hello guys, i'm doing this post today because i need help with something .. i extracted this code from a superpowers script, i think that's all the code, i want to separate this code from all the script and that can be used with command, or always active, but i don't know what to delete to achieve that, could you guide me?this script basically consist in a superjump, if the key is pressed the player jumps very high until the button is released

superjumping = 0

function rocketjump()
	startrocketjumpingthing = nil
	if getControlState("jump") == true then
		local task = getPedSimplestTask(getLocalPlayer())
		if task == "TASK_SIMPLE_IN_AIR"  and superjumping == 0 then
			if isTimer(startgroundchecktimer) then
				resetTimer ( startgroundchecktimer)
			else
				startgroundchecktimer = setTimer ( startjumpgroundcheck, 300, 1)
			end
			superjumpgroundcheck = 0
			addEventHandler("onClientRender",getRootElement(), rocketplayer )
			addEventHandler("onClientRender",getRootElement(), jumpgroundcheck )
			triggerServerEvent ("onSpeedChange", getLocalPlayer(), "jumping")
			jumpstart = getTickCount()
			superjumping = 1
		end
	end
end

function triggersuperjump(key, keyState)
	if getElementData( getLocalPlayer(), "transport_power" ) == "superjump" then
		if keyState == "down" then
			local px,py,pz = getElementPosition( getLocalPlayer () )
			local isclear = isLineOfSightClear ( px, py, pz,px, py, pz-3,true,true, true, true,true,true, false, getLocalPlayer() )
			if isTimer(startrocketjumpingthing) == false and isclear == false then
				startrocketjumpingthing = setTimer ( rocketjump, 650, 1)
			end
		elseif keyState == "up" then
			removeEventHandler("onClientRender",getRootElement(), rocketplayer )
		end
	end
end
