Lua TFs 1.2 nil value problem

[Szafi]

Hello.

I convert tfs 0.4 my scripts to 1.2. I do not know what could be wrong.

Console:

Lua Script Error: [GlobalEvent Interface]

add this to your data/lib/compat/compat.lua or data/global.lua

function getThingfromPos(pos)
    local tile = Tile(pos)
    if tile == nil then
        return pushThing(nil)
    end

    local thing
    if stackpos == STACKPOS_TOP_MOVEABLE_ITEM_OR_CREATURE then
        thing = tile:getTopCreature()
        if thing == nil then
            local item = tile:getTopDownItem()
            if item ~= nil and item:getType():isMovable() then
                thing = item
            end
        end
    elseif stackpos == STACKPOS_TOP_FIELD then
        thing = tile:getFieldItem()
    elseif stackpos == STACKPOS_TOP_CREATURE then
        thing = tile:getTopCreature()
    else
        thing = tile:getThing(pos.stackpos)
    end
    return pushThing(thing)
end

also replace

getResult

for

storeQuery

 

[Codex NG]

Try omitting the stackpos from the table and see what you come up with.

It will never work, because "getResult" isn't in tfs 1.2 -> "storeQuery"

 

[slavi]

and yea try to remove stackpos. or try

Position(x, y, z)

 

[Szafi]

and yea try to remove stackpos. or try
