Problems with 2-Dimensional Arrays

Okay, I got the simplest piece of code ever, but for some reason it won't work. All I want to do is initialize a 2-dimensional array.
The code is:

Code: [Select]

var grid[10,20];

It gives an error at the 1. What the hell am I doing wrong?

Re: Problems with 2-Dimensional Arrays

You don't have to initialize variables in GameMaker, the only thing that's good for is keeping variables localized to certain scripts, and if thats your goal drop the brackets and numbers in them.

so just use

var grid;

You can't really initialize an array with a size to start out with.

I've done it (sorta)!  Bloom Lighting in GameMaker, and 3D mode too!  Check out the awesome Screen Saver.

I don't understand... how do you make an array then?

EDIT: Oh, nevermind, I get it now. Thanks for the help!

Just start assigning values to it.  GM is weird with variables, you don't have to make them all, just start using them, of course you have to assign them a value first because it'll give you an error if you try to get something that isn't there.
