Creating a two dimensional array?

[Foxthorn]

Okay, another problem...I'm trying to use a two dimensional array to store some settings, like this:

someArray[Name][Value] = 4

But if I just type that into the editbox, I get this:

[string "someArray["Name"]["Value"] = 4"] line 1:
   attempt to index global 'someArray' (a nil value)

Halp?

You first have to create the array/table, as well as the table in the first dimension:

someArray = {}
someArray[Name] = {}

Ah, that worked. Thanks.

Another question, is there any way to loop through every FontString that's parented to a specific frame, and do something to each one?

New problem...Still working on that two-dimensional array. Here's some of the code:

function WXP_Draw(WXP_otherXP,WXP_otherMax,WXP_Name,WXP_Level)
WXP_Old["otherXP"][WXP_Name] = WXP_otherXP

And I get this error:

attempt to index field 'otherXP' (a string value)

Even after I do

WXP_otherXP = tonumber(WXP_otherXP)

I still get the same error.
WXP_otherXP is a number (76957) and I can perform arithmetic on it (before doing tonumber).

Hmm...if WXP_Old["otherXP"] is a number, will trying to use WXP_Old["otherXP"][WXP_Name] even work? (first it was a number/string, and now you're trying to make it another array thing)

how are you defining WXP_Old? is there a "otherXP" index that contains a table? that is, did you ever do a "WXP_Old["otherXP"] = {}" or similar?

also, WXP_Old["otherXP"] can be written as WXP_Old.otherXP which might be a little easier on the eyes. written this way, it's also clear that it's not really a multidemensional array like it is in C so much as a table (WXP_Old) that contains another table (otherXP).

You could fetch all regions of the frame with :GetRegions() and check if they're font strings.

local regions = { frame:GetRegions() }
for _, region in pairs(regions) do
  if(region:IsObjectType("FontString")) then
    doSomething()
  end
end

Yeah, originally it was basically if WXP_Old["otherXP"] = nil, set it to 0.

So I changed it to set it to {} instead of 0. I have to restart my game and clear out the old SavedVariable to fix it since it's still saving it as 0, but I'm questing with a friend so I'll have to do it later.

Thanks! I'll use that instead of the longer loop-through-party-and-use-each-member's-name method I'm using now

Yet another problem...here's the code:

_G["WXP_Text_"..WXP_Name]:SetText(WXP_TextString..WXP_Name.."("..WXP_Level..")")

And here's the resulting error...

attempt to index field '?' (a nil value)

WXP_TextString, WXP_Name, and WXP_Level are all strings, and I think WXL_Text_(WXP_Name) does exist at that point, it may not though. If it didn't, is that what would be causing this error? And if not, then what is?

Note: When you first log in to a character, you get this error, and the FontString that this modifies doesn't exist. However, when you do a ReloadUI, you don't get the error, the FontString appears, and all works fine. So obviously there's something that's not happening when you first log in, but does happen after a ReloadUI.

If someone would be willing to take a look at the full source, say so and I can get it to you, it'd help a lot if I could get this sorted out.

The font string does not exist yet, so the global you're looking for ("WXP_Text_"..WXP_Name) is nil. To perform a method (SetText()), Lua expects the object to be a table with all its methods and other stuff. So it tries to do a table lookup for ["SetText"] but there isn't a table yet.

It may only be happening on login because the fontstring is waiting on certain events to be created which could take longer during login than during a /reloadui.

Hope this makes sense...
