i m working 3D game..

when i am store the instantiate(paintobject) in my list? how identify the system when my fill up whole plane?? and game over and when fillup whole plane then going to the next scene..

how identify my game when my plane fill up and going next scene??

what i am trying to do when fill up my whole plane going to nextscene??

Empty Plane:

fillup plane:

public float speed = 10f; private RaycastHit hit; public GameObject paintcube; float maxdistance = 0.51f; bool moves;

private void FixedUpdate()
{
    Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 3, Color.green);
    if (Physics.Raycast(transform.position,transform.TransformDirection(Vector3.forward), out hit, maxdistance/*,layerMask*/))
    {
        if (hit.collider.gameObject.tag == "myobstacle")
        {
            moves = false;                                                         
        }
        if(moves)
        {
            movepaint();
        }
    }
}   
public void movepaint()
{
    if (moves)
    {
        MyList.Add(Instantiate<GameObject>(paintcube, position, transform.rotation));
    }
}       

    

In my game, the player is presented with a plane containing obstacles (orange / blue) and regions of empty space (white).

The player moves their green cube around the empty space, which instantiates a trail of green cubes behind it, painting the path they've travelled.

I need to detect when the player has painted all of the empty space, so that they can proceed to the next level.

Initial state of the board:

When the player has painted all of the empty space:

Currently I store my instantiated paint objects in a list.

But I don't know how to check that the objects in this list cover all of the empty space. How can I do that?

public float speed = 10f;
private RaycastHit hit;
public GameObject paintcube;
float maxdistance = 0.51f;
bool moves;

    

private void FixedUpdate()
{
    Debug.DrawRay(transform.position, transform.TransformDirection(Vector3.forward) * 3, Color.green);
    if (Physics.Raycast(transform.position,transform.TransformDirection(Vector3.forward), out hit, maxdistance/*,layerMask*/))
    {
         if (hit.collider.gameObject.tag == "myobstacle")
         {
             moves = false;                                                         
         }
         if(moves)
         {
             movepaint();
         }
     }
}    

public void movepaint()
{
     if (moves)
     {
         MyList.Add( Instantiate<GameObject>(paintcube, position, transform.rotation) );
     }
}
