Lua Monster Lever Script, doRemoveCreature.

[Cornwallis]

I'm sick of this script lol, everything about it works fine except for the doRemoveCreature, and I'm not sure how to make it remove random creatures in a 1x1 area, for example "exori gran". I tried a lot of stuff, nothing wants to work.. 0.3.1pl2. If possible, can the tiles be cleaned too on 1945? If there is a function I must add to do so, let me know, thanks in advance, any advice is appreciated!

local t = {
	[{1, 14}] = "Rotworm",
	[{15, 39}] = "Dragon",
	[{40, 79}] = "Dragon Lord",
	[{80, 179}] = "Demon",
	[{180, 3000}] = "Bog Spider"
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
local fromPos = {x=fromPosition.x+1,y=fromPosition.y,z=fromPosition.z}
local toPos = {x=toPosition.x,y=toPosition.y-1,z=toPosition.z}
	if(item.itemid == 1946) then
		for k, v in pairs(t) do
			if(getPlayerLevel(cid) >= k[1] and getPlayerLevel(cid) <= k[2]) then
				doSummonCreature(v, getPlayerPosition(cid))
				doSummonCreature(v, getPlayerPosition(cid))
			end
		end
	elseif(item.itemid == 1945 or getPlayerLevel(cid) > k[2]) then
		doPlayerSendCancel(cid, "Sorry, not possible.")
		doRemoveCreature(isMonster(isInArea(fromPos, toPos)))
		doRemoveCreature(isMonster(isInArea(fromPos, toPos)))
	end
return true
end

Forgot the error;

[16/06/2012 07:56:09] data/lib/function.lua:258: attempt to index local 'toPos' (a nil value)
[16/06/2012 07:56:09] stack traceback:

Edit; here is the function in lib/function.lua:

function isInArea(pos, fromPos, toPos)
	if(pos.x >= fromPos.x and pos.x <= toPos.x) then
		if(pos.y >= fromPos.y and pos.y <= toPos.y) then
			if(pos.z >= fromPos.z and pos.z <= toPos.z) then
				return TRUE
			end
		end
	end

	return FALSE
end

Sorry for all these edits, but here is what I got to after reviewing that function. If this one is closer you can use it, if it isn't then use the above one.

local t = {
	[{1, 14}] = "Rotworm",
	[{15, 39}] = "Dragon",
	[{40, 79}] = "Dragon Lord",
	[{80, 179}] = "Demon",
	[{180, 3000}] = "Bog Spider"
}

function onUse(cid, item, fromPosition, itemEx, toPosition)
local fromPos = {x=fromPosition.x+1,y=fromPosition.y,z=fromPosition.z}
local toPos = {x=toPosition.x,y=toPosition.y-1,z=toPosition.z}
	if(item.itemid == 1946) then
		for k, v in pairs(t) do
			if(getPlayerLevel(cid) >= k[1] and getPlayerLevel(cid) <= k[2]) then
				doSummonCreature(v, getPlayerPosition(cid))
				doSummonCreature(v, getPlayerPosition(cid))
			end
		end
	elseif(item.itemid == 1945 or getPlayerLevel(cid) > k[2]) then
		doPlayerSendCancel(cid, "Sorry, not possible.")
		doRemoveCreature(isMonster(isInArea(getCreaturePosition(cid), fromPos, toPos)))
		doRemoveCreature(isMonster(isInArea(getCreaturePosition(cid), fromPos, toPos)))
	end
return true
end
