Variable Arrays of Arrays

Is there any way to create an array of an array? I have a really weird complex leveling system that I'm trying to implement, and I can't quite figure out the best way to do it yet. Essentially, I'm trying to emulate the Hero Ability Choosing system. The reason I'm not actually using the built-in WC3 version is because I want each hero to have six abilities that they level as time goes on (not 5). Does anyone know how to create an array of an array?

Suppose I wanted to make an array of item arrays (2D array). Is that data-type possible?

The easiest way is to use Game Cache, you could also emulate 2D arrays.

[0,0] = 0
[1,0] = 1
[2,0] = 2

[0,1] = 3
[1,1] = 4
[2,1] = 5

[0,2] = 6
[1,2] = 7
[2,2] = 8

Eventually you can simulate 2d array on 1d array by

4x6 array:

array[6*x+y] = 123

or u could just do this:
array[00 01]=5
array[00 02]=5
array[00 03]=8
array[00 04]=1
...
array[01 01]=9
array[01 01]=5
array[01 01]=9
array[01 01]=3
...
array[99 99]=12

this array allow u to have 2D array, with each 1D array can contain 100 different values (100*100).
The space i made was just to show u the concept, they will become like array[0235] in wc3.
since array in wc3 doesn't accept infinite array integer, so u can only use 4 numbers i think.
With this you can also make 4d arrays, but then u can only have up to 10 values in each array. example:
array[0 5 3 4] = 5
array[2 5 3 1] = 4

I used this method on making lvl spawn:
lvl=1
unit_type[lvl*100+0]=tauren
unit_type[lvl*100+1]=grunt
unit_type[lvl*100+2]=peon
...
if you look at this as array it will be
unit_type[01 00]=tauren
unit_type[01 01]=grunt
unit_type[01 02]=peon

so for lvl 2 i just set lvl=lvl+1
then the next array will be

unit_type[02 00]=unit1
unit_type[02 01]=unit2
unit_type[02 02]=unit3

As you can see, i can have 100 (0 to 99) different unit types for each lvl

But if you want to use 2D array with bigger amount of values, then you can always use gamecache, which is amazing for arrays. And since gamecache can contain big integers, so you can actualy fake big dimensional array, maybe up to 100*100*100*100, or even higher than that

not really, more like 80*100, since the max array size is something above 8000.

Anyway, this is rather simplified, as Zoxc already pointed out, when simulating 2d arrays, you can have any array sizes, not just powers of ten, as long as the total number of items you can store in it is below 8000+something.

Valid array indexes goes from 0-8191.

Thanks, that makes very logical sense. I can't believe I didn't think of that myself. How do i give "rep" to you guys?

Click on this little button close to a person's username, and a window will pop up (will look a bit different if you use another theme than the default one, but it will be in the same place).

In that window there is a field where you can write the reason that you give a person reputation points. To give the points, click on the button.

thanks! great work on the spell contest, btw
