Problems editing a level from script

Hello, I’m trying to create levels dynamically. To do so, I have created a scene and I edit the ammount of components I have in the scene using a script. Here’s the code I’m using:

 public class BuildScene : MonoBehaviour
{
public Transform square;

void Start()
{
    int numFilas = ApplicationModel.numberRows;
    int numObj = 3;

    float posY = 2.5f;
    for (int i = 0; i < numFilas; i++)
    {
        for (float j = 0; j < numObj; j++)
        {
            float posX = -0.9f;
            Instantiate(square);
            
            square.transform.localScale = new Vector3(0.6f, 0.6f, 0.1f);
            square.transform.position = new Vector3(posX+j, posY-i, 0);
        }
    }
}

Public Transform square is a prefab of a 3dcube with a material.

numberRows changes deppending on the button you press (level 1 = 1 row, level 2 = 2 rows, etc.).

The problem is that the first time you enter a level the last cube of the last row doesn’t appear, or is in a wrong position, but the second time you enter into that level it works perfectly. Any ideas?

If you want I pass you the project (is really small right now) so you can execute it.

You need to use the instantiated square’s new reference instead of the one you’re basically copying from the inspector.

Change your Start method to use a local variable that is a reference to the new game object. This will also lessen the complexity of the code a bit since you’re already dealing with a transform which you where before… anywho

 void Start()
 {
     int numFilas = ApplicationModel.numberRows;
     int numObj = 3;
     float posY = 2.5f;
     for (int i = 0; i < numFilas; i++)
     {
         for (float j = 0; j < numObj; j++)
         {
             float posX = -0.9f;
             Transform newSquare = Instantiate(square);
             
             newSquare.localScale = new Vector3(0.6f, 0.6f, 0.1f);
             newSquare.position = new Vector3(posX+j, posY-i, 0);
         }
     }
 }

Now stuff looks like (1 row):

And now 6 rows:
