The code i have right now only goes until 9 on each X and Y array. what i want to know is how would i continue it ( ill explain more after the code)

var instantiateObject : Transform;

var gridX = 10;
var gridY = 10;


function Start () {
//create two new arrays for the x and y axis
tileArrayY = new ArrayList();
tileArrayX = new ArrayList();


	for ( var x = 0; x < gridX; x++){
		
		for (var y = 0; y < gridY; y++){
		
			var myName = Instantiate(instantiateObject, Vector3(x *.5,0,y * .5), Quaternion.identity);
			myName.name = "x: " + x + "y: " + y;
			// assign each y and each x to the individual arrays
			if( y % gridY == 0 ){
			tileArrayY.Add(myName.gameObject);
			}
			
			if( x % gridX == 0 ){
			
			tileArrayX.Add(myName.gameObject);
				
			
			}	
		}
		
 	} 
	// check those arrays
	for( var i = 0; i < 20; i++){
	
		print("This is your YArray: " + tileArrayY*);		*

_ print("This is your XArray: " + tileArrayX*);_
_ }_
_}_
so what i am getting from this code is:
Xarray:
x:0 y:0
x:1 y:0
x:2 y:0
x:3 y:0
_…_
x:8 y:0
x:9 y:0
Yarray:
x:0 y:0
x:0 y:1
x:0 y:2
x:0 y:3
_…_
x:0 y:8
x:0 y:9
but i want them to do this instead:
Xarray:
x:0 y:0
_…_
x:9 y:0
x:0 y:1
_…*_
x:9 y:1
i hope this makes sense? ask me to clarify if you dont understand it and ill be happy to help you help me :slight_smile: thanks

Changing the loop to:

for ( var y = 0; x < gridY; x++){

   for (var x = 0; y < gridX; y++){

     var myName = Instantiate(instantiateObject, Vector3(x *.5,0,y * .5), Quaternion.identity);
     myName.name = "x: " + x + "y: " + y;
       
     tileArrayX.Add(myName.gameObject);

   
   }

}

Will give you one array, tileArrayX of the form you said. Note that the y loop has been moved to the outside.

I would stay away from the Class-based Arrays in Unity (and in general) - the classes like “Array” and “ArrayList”. I have had nothing but trouble with them.

Here is the basic syntax for working with built-in multi-dimensional arrays in JavaScript, which I have never had any problems with:

var myArray : int[,] = new int[5,5];
myArray[0,1] = 42;
for(var X : int = 0; X < myArray.GetLength(0); X++)
    for(var Y: int = 0; Y < myArray.GetLength(1); Y++)
    {
        myArray[X,Y] = X+Y;
        Debug.Log(myArray[X,Y]);
    }

var threeDimensionalArrayOfObjects : GameObject[,,] = new GameObject[9,6,42];
