[Trigger] 2d integer array?

[Mendel]

Well, i know there is a normal integer array and hashtables, but what if i need a 2d ( 2 dimensional ) integer array?
using the hashtable is the only way?

Well it depends on the size.

Like all 2D arrays, it can only have a finite size.

You use simple maths to make one in the indicies of a normal array.
d1*ds2+d2
d is the demension while ds is the demension size. As you can see d1 has no difined size but is restricted by the max array size (8192).

Or you can use a dynamic array and extend the limit so that it can process more indexes. This is of course just a vJass trick, it does not "take away" those limits.

type int2d extends integer array [200, 40000]

This will make an array with 200 maximum instances, each with a size of 200.

A hashtable is a 2d integer array if you want it to be one

Berb, that purly puts multiple arrays in series and probably uses the same formla I provided. In our case thats 4 arrays in series.

SlayerII, although hashtables do seem to act like 2D arrays and can be used as them, it is still more efficent to use a proper array in a 2D mode like that I provided. Hashtable lookup is great for wide range data while keeping lookup speeds near constant but can never beat a simple array.

Yes. I know. I am advising him to use features of vJass to his advantage.
