Convert vector2int to vector3

Question

Hi guys,

I have the following situation in my game:

I have a matrix 6x6 and I store the player's position in a vector2Int, as you can see in the image.

And when he is hit by a bullet, I'd to instantiate on his left, right, behind and front a gameobject. However I can't use a vector2int to do it, I've already tryed to do this, but I got an error message:

 private void OnTriggerEnter(Collider other)
     {
         if (other.transform.tag == "Player2")
         {
             player.Health += Healing;
 
             Instantiate(Flame, player.GridPosition.y+1, Quaternion.identity);
             Instantiate(Flame, player.GridPosition.y -1, Quaternion.identity);
             Instantiate(Flame, player.GridPosition.x + 1, Quaternion.identity);
             Instantiate(Flame, player.GridPosition.x - 1, Quaternion.identity);
             Destroy(this.gameObject);
 
         }
     }

Is there a way that I could convert this vector2int into a vector3? How could I do it?

I think the problem isn't that.

In this line:

Instantiate(Flame, player.GridPosition.y+1, Quaternion.identity);

player.GridPosition.y+1 is not a Vector2Int, it is just a int.

Try this:

 Instantiate(Flame, player.GridPosition+ new Vector2Int(0,1), Quaternion.identity);
 Instantiate(Flame, player.GridPosition + new Vector2Int(0,-1), Quaternion.identity);
 Instantiate(Flame, player.GridPosition + new Vector2Int(1,0), Quaternion.identity);
 Instantiate(Flame, player.GridPosition + new Vector2Int(-1,0), Quaternion.identity);

What is the Error Message?
