Two-Dimensional Arrays

I tried both

Code:

gUnitsVoidPoints = {}
for i=1, 10 do
	gUnitsVoidPoints[i] = {}
	for j=1, 10 do
		gUnitsVoidPoints[i][j] = 0
	end
end

and

Code:

gUnitsVoidPoints = {}
for i=1, 10 do
	gUnitsVoidPoints[i] = {}
	for j=1, 10 do
		gUnitsVoidPoints[i*10 + j] = 0
	end
end

But when I try to get the value (if gUnitsVoidPoints[unit:GetOwner()][unit:GetID()] ~= nil then) I get:

UnitPanel.lua:718: attempt to index field '?' (a nil value)

What am I doing wrong?

unit:GetID() will be much,much greater than 10!

In my current game

Code:

> for pUnit in Players[0]:Units() do print(pUnit:GetID()) end
 WorldView: 8192
 WorldView: 16385
 WorldView: 24578
 WorldView: 65539
 WorldView: 40964
 WorldView: 57349
 WorldView: 81927
 WorldView: 98312
 WorldView: 114697

Your best bet will be something like, to create the unit's void point entry as needed

Code:

local iUnit = unit:GetID()
local playerVoidPoints = gUnitsVoidPoints[unit:GetOwner()]
if (playerVoidPoints[iUnit] == nil) then playerVoidPoints[iUnit] = 0 end

-- Now you can use gUnitsVoidPoints[unit:GetOwner()][unit:GetID()]

I'm getting this:

Lua\Lib\UnitPanel.lua:1756: attempt to index local 'playerVoidPoints' (a nil value)

For reference, the code:

Spoiler :

I REALLY am terrible with tables.

That's 'cos' you no longer have the loop that creates the player arrays

From post #1 ...

Code:

gUnitsVoidPoints = {}
for i=1, 10 do
	gUnitsVoidPoints[i] = {}
end

which should actually be 0 to MAX_MAJOR_CIVS (not 1 to 10)

I will never let go of the noob stick.

(It works now, thank you very much!)
