Position - simple creation of position, returns LUA_ERROR if position is invalid

[Colandus]

This function will create a position and check if it's valid or not. You don't need this x=, y=, z=, stackpos=

TFS 0.3+ put in data/lib/functions.lua
TFS 0.2 or other put in data/global.lua

function Position(x, y, z, stackpos)
	if tonumber(x..y..z) then
		local pos = {x=tonumber(x), y=tonumber(y), z=tonumber(z)}
		if tonumber(stackpos)then
			pos.stackpos = tonumber(stackpos)
		end
		
		return pos
	end
	
	return LUA_ERROR
end

Usage:

local pos = Position(143, 543, 324) -- Add ", 1" for stackpos 1 or w/e stackpos u want

Using it for SURE! Thanks!

Useful but I would do it without these checks (It won't do nothing, because if pos is wrong, then lua will print it)

Indeed, but now after this edit they're worth it
Now if you make like talkaction:

function onSay(cid, _, param)
    if #param == 0 then
        doPlayerSendCancel(cid, "Please enter a text and position!")
        return TRUE
    end

    local data = string.explode(param, "|")
    if not data[2] then
        doPlayerSendCancel(cid, "Please enter a position!")
        return TRUE
    end

    local tmp = string.explode(param, " ")
    local pos = Position(unpack(tmp))
    if pos == LUA_ERROR then
        doPlayerSendCancel(cid, "Invalid position specified!")
        return TRUE
    end

    doCreatureSay(cid, data[1], TALKTYPE_SAY, pos)
end
