Question

Hello, I need to be pointed in the right direction with Unity's TextAsset component.

I will have a .txt file with 400 numbers, without spaces. ex: "010100111000101010" I want to have unity read each indivdual character, if it detects a "0" it will move up a value(position) and if it detects a "1", it will add a prefab (in this case a cube) before moving up a value. The end result will be a 20x20 grid of blocks in pre-determined positions.

I want to integrate it into this script somehow:

var cube : Transform;
function Start () {
    for (var y = 0; y < 5; y++) {
        for (var x = 0; x < 5; x++) {
            var cube = Instantiate(cube, Vector3 (x, y, 0), Quaternion.identity);
        }
    }
}

Can anyone help me out with this?

Place your text file into Unity's assets folder. Then make the script changes below, and drag a reference to the text asset into the "dataFile" variable below.

var dataFile : TextAsset;
var cube : Transform;

function Start () {
    for (var y = 0; y < 5; y++) {
        for (var x = 0; x < 5; x++) {
            var charNum = (y*5)+x;
            if (dataFile.text[charNum] == "1") {
                var cube = Instantiate(cube, Vector3 (x, y, 0), Quaternion.identity);
            }
        }
    }
}

That should do it! (untested though... give me a shout in the comments if it doesn't work!)
