Lua How does "doTransformItem" work?

[ziggy46802]

Here is my script that I was just messing around with, what I wanted it to do was to just change a tile at a certain location to another id, example would be to pull a lever to make a bridge appear, but my script just did nothing when I pulled the lever. Yes, I did search around (and yes I did put it in actions.lua and the lever has the right unique id, thats not the problem) and I did try so there it is:

pohlever.lua

function onUse(cid, item, frompos, item2, topos)
	doTransformItem(item.uid, item.itemid + 1)
	doTransformItem( cid, 103, { x = 1377, y = 1088, z = 7 }, 407, { x = 1377, y = 1088, z = 7} )
	if item.actionid ~= 0 then
		doSetItemActionId(item.uid, item.actionid)
	end
	doDecayItem(item.uid)
	return true
end

I just figured cid, item, frompos, item2, topos was how it worked but I dont know....

Here is another attempt that failed and just did nothing

function onUse(cid, item, frompos, item2, topos) 
gatepos = {x=1377, y=1088, z=7, stackpos=1} 
getgate = getThingfromPos(gatepos) 

if item.uid == 1017 and item.itemid == 1945 and getgate.itemid == 103 then 
doRemoveItem(getgate.uid,1)
doCreateItem(407,1,gatepos) 
doTransformItem(item.uid,item.itemid+1) 
elseif item.uid == 1017 and item.itemid == 1946 and getgate.itemid == 407 then 
doCreateItem(103,1,gatepos) 
doTransformItem(item.uid,item.itemid-1) 
else 
doPlayerSendCancel(cid,"Sorry, not possible.") 
end 
return 1 
end

Here is yet another attempt that does NOTHING

local pos, e = {x=1377, y=1088, z=7}, 0
local f = function(p)
	doCreateItem(407, 1, pos)
	doTransformItem(getTileItemById(p, 1946).uid, 1945)
end
 
function onUse(cid, item, fromPosition, itemEx, toPosition)
	if item.itemid == 1945 then
		doRemoveItem(getTileItemById(pos, 103).uid)
		e = addEvent(f, 5 * 60 * 1000, fromPosition)
		doTransformItem(item.uid, 1946)
	else
		stopEvent(e)
		e = 0
		f(fromPosition)
	end
	return true
end

What am I doing wrong? Is it something obvious that I'm not seeing?
