Solved Globalevent: attempt to call global

[swevaman]

Well basically here is the screenshot of the error

and here is the script:

function onThink(interval)

local Pos = Position
if not Position then
    Pos = function (x, y, z)
        local position = {x = 0, y = 0, z = 0}
        if(tonumber(x .. y .. z) ~= nil) then
            position = {x = x, y = y, z = z}
        end
        return position
    end
end
end
                        
function modify_pos(old, new)
    return Pos(new.x and old.x+new.x or old.x, new.y and old.y+new.y or old.y, new.z and old.z+new.z or old.z)
end


local SPEED = 300         --fastest = 1, slowest = 1000
local PLATFORM = 420     --itemid of platform
local FLOOR = 460         --invisible tile
local path = 
    {
        [NORTH] = {y = -1},
        [EAST] = {x = 1},
        [SOUTH] = {y = 1},
        [WEST] = {x = -1}
    }


function getPosition(position, lastPosition)
    for direction, mod in pairs(path) do
        local pos = modify_pos(position, mod)
        if (getTileItemById(pos, FLOOR).uid > 0) and not doComparePositions(pos, lastPosition) then
            return pos
        end
    end
    return lastPosition
end

function doPlatform(position, lastPosition)
    local posEx = getPosition(position, lastPosition)
    doTransformItem(getTileItemById(posEx, FLOOR).uid, PLATFORM)
    doCleanTile(position)
    for i = 1, getTileInfo(position).things do
        position.stackpos = getTileInfo(position).things-i
        local cid = getThingFromPos(position).uid
        if isCreature(cid) then
            doTeleportThing(cid, posEx, false)
        end
    end
    doTransformItem(getTileItemById(position, PLATFORM).uid, FLOOR)
    return addEvent(doPlatform, SPEED, posEx, position)
end


function onStartup()
    doPlatform(Pos(2115, 2061, 6), Pos(2115, 2062, 6))
    return true
end

I just need to know what this means.

It means the server is not recognizing 'pos' as a local key available in your script. If it cannot find 'pos' as a local key, it attempts to find it as a global key. If that also fails, the server will print that error.

If you want me to help you with it, feel free to tell me.

*EDIT-1*: And by the way, this error can occur in any type of script, not just globalevents. So don't get confused by it.

A clue to help you fix, scripts are case sensitive.

Remove function onThink(interval) and this end.

local Pos = Position
if not Position then
    Pos = function (x, y, z)
        local position = {x = 0, y = 0, z = 0}
        if(tonumber(x .. y .. z) ~= nil) then
            position = {x = x, y = y, z = z}
        end
        return position
    end
end

The reason for this error is because it's now local for function onThink, so a nil value in an other function.

I already fixed it up for him
The problem wasn't just that, he was trying to use this script in an OTSERVER 0.6.3 based distribution.
