Teleport that checks if one player is left

[Tarielle]

Is it possible to make a teleport to check if there is only one player left in a area?
I mean like a arena, that you cant walk in the teleport until the other player is defeated..

i think maybe if u make a portal with no coordinates and then have a stepin script that checks for players in side an area and if the amount of players is less then 1 then you tp the player otherwise you get message you are still in a duel

Yea, but I kinda dont know the function that checks if there is just one left :<

global.lua

-- Area iterator by Colandus @ ******.net
function mapArea(fromPos, toPos, stack)
	local pos = {x=fromPos.x, y=fromPos.y-1, z=fromPos.z}
	return function()
		if (pos.y < toPos.y) then
			pos.y = pos.y+1
		elseif (pos.x <= toPos.x) then
			pos.y = fromPos.y
			pos.x = pos.x+1
		else
			pos.x = fromPos.x
			pos.y = fromPos.y
			pos.z = pos.z+1
		end
		if (pos.x <= toPos.x and pos.y <= toPos.y or pos.z < toPos.z) then
			if (stack == nil) then
				return pos
			else
				pos.stackpos = stack
				return pos, getThingfromPos(pos).uid
			end
		end
	end
end

local fromPos = {x=x, y=y, z=z}
local toPos = {x=x, y=y, z=z}

for _, thing in mapArea(fromPos, toPos, 253) do
    if isPlayer(thing.uid) == TRUE then
        -- player found, now what?
        return TRUE
    end
end
-- no player was found, continue?
return TRUE

add the onStepIn or w/e you want yourself

Pointless, you can use global storage for that.

@Colandus:
Do that really check if there is only one? I mean it shall not possible to walk inside the teleport if there is two persons in the area, but it shall be possible if there is only one.

@Elf:
How?

Pointless, you can use global storage for that.

I'm not trying to remake his whole system, just to answer his question

But sure, you could use storage values for checking

How do I use the:

for _, thing in mapArea(fromPos, toPos, 253) do

How should I edit the 'for _,'. Example please Because it dosn't workt if you execute the script with 'for_,'.
