[Solved] 2D Arrays for a Grid?

[Evil Gamer]

Hello. With all the buzz about Warcraft 3 Reforged, I figured I would try my hand at mapping again. So my issue is that it doesn't seem Warcraft 3's editor supports multidimensional arrays like Starcraft 2 does. Would anyone happen to know if there is a way to simulate a 2d array with a little world editor trickery? What I want to use it for is to detect adjacency between different Regions for the purpose of moving pieces along a 2d game board. I didn't want to have to create a bunch of if/then/else functions since my board has 66 different region squares, and was hoping for a simpler way of going about this. Thanks in advance to whoever can help.

JASS has 2d arrays natively now. In GUI index [x][y] can be mapped to [(x-1)*MAX_Y + y] to simulate a 2D array.

Lua supports multidimensional arrays.

Thanks for the response. I don't know LUA or JASS, but I can try using pyro's method.

You can also use hastables, lets you store a value to two seperate integers, parent and child

I have read about them while looking for solutions regarding my problem, but I am not sure how I would go about using them. It was sufficient enough to simulate 2d arrays by using [(x-1)*MAX_Y + y].

[(x-1)*MAX_Y + y]

This will result in a negative (invalid) index for var[0][0].

Sure (it’s actually invalid for all 0<=x<MAX_Y), but my presumption was that the OP was using GUI and such users generally index their arrays from 1. The way I wrote it maps indexes starting from x=1 to [1][1]..[1][MAX_Y] rather than x=0 to [0][0]..[0][MAX_Y-1].

Not that any real change would be needed anyway due to JASS arrays being dynamic arrays. At most a few wasted indices at the array start. These would mostly be masked due to how arrays expand in powers of two (according to what people said long ago).
