Table (attempt to index field '?' <a nil value>)

[FUNExtreme]

Hello,

I'm new to lua as I come from samp and I've stumbled upon a problem that I couldn't solve by searching the wiki, forum, etc

So I've come along tables and understand how they work by now although I still seem to have some problems.

code removed

As you see I created a table wich will hold the current team and skin for each player. But when I try to use these tables in a function wich is here "SetElementModel" I get the error

*Resource location*: attempt to index field '?' <a nil value>

And I really don't understand why it gives this error,

I hope that someone of you can light me up on this one so that I won't stumble upon this problem again.

Greetzz,

FUNExtreme

source is nil. Are you sure you're doing it in an event handler? Either way, add a debug output with tostring(source) and see what it is.

And if you can't figure it out, please try to post as much as your script as possible. Preferably the whole file. It makes it a lot easier for people to figure out.

Well I tried adding tostring allready, just as I tried tonumber and both gave the error. I'll show you the whole join handler

Well I tried adding tostring allready, just as I tried tonumber and both gave the error. I'll show you the whole join handler

function serverJoinHandler()
currentTeamID[source] = 1
currentSkinID[source] = 1
setElementModel(source, playerSkins[currentTeamID[source]][currentSkinID[source]])
setElementPosition(source, 1474.43, -2286.91, 42.42) -- for testing purpose
-- above line should be edited later on
local PosX, PosY, PosZ = getElementPosition(source)
local PosRot = setPedRotation(source, 1)
setCameraMatrix(source, PosX, PosY+2, PosZ, PosX, PosY, PosZ)
fadeCamera(source, true)
triggerClientEvent("createSelectionGUIEvent", gRoot, CreateSelectionGUI)
end
addEventHandler("onPlayerJoin", gRoot, serverJoinHandler)

Where is your playerSkins? To me, it looks like playerSkins is the problem maker.

As you stated the playerSkins seems to be the problem. When using currentTeamID[tostring(source)] then it will return the correct number (in this case 1)

Here you have the code that shows how the playerSkins is built-up

Side-note: The table playerSkins is in another .lua file (wich doesn't give trouble when I use a number instaid of the table)

Sorry for the double post but I fixed the problem.

There was a typo in the file where playerSkins gets information from wich made that it didn't get the information, therefore the table didn't get filled and all the tries returned false
