Nested loop queston

Question

I'm trying to create a 5 x 5 grid of spheres using a nested loop. it looks like this:

public GameObject ball:

for (int y = 0; y < 5; y++){

     for ( int x = 0; x < 5; x++){
         GameObject spheres = GameObject.Instantiate(ball); 
         Vector3 xPos = new Vector3((x * 3), 0, 0);

         spheres.transform.position = xPos;
     }

     Vector3 yPos = new Vector3(0, (y *3), 0);
     transform.position = yPos;

 }

I'm getting the correct number of spheres and the x position offset is working but the Y position is not. Any ideas??? ..or is there a better way to do this?

Thanks,

Jeff

Do all of your placements inside the inner for loop so that it is being applied to all balls, right now you are assigning the xpos to all balls but the ypos only on those inside the first for loop.

Edit: The yPos isn't being applied to the balls at all, it is setting the y pos of the GameObject that this script is on.

 public GameObject ball:
 
 for (int y = 0; y < 5; y++){
      for ( int x = 0; x < 5; x++){
          GameObject spheres = GameObject.Instantiate(ball); 
          Vector3 pos = new Vector3((x * 3), (y * 3), 0);
          spheres.transform.position = pos;
      }
  }

That way each ball will get both of its x and y positions
