Hi everybody !

I’m making a little game with objects appearing when I click. I have this code actually making things work : everytime I use the mouseclick a Gameobject is created where I click on the 2d game I created.

```
//Changed to an array of objects assign as many as you have in inspector
var boxes : GameObject[];
var boxCounter : int;
function Update()
{
if(Input.GetMouseButtonDown(0))//Checks to see if left mouse button was clicked.
{
CreateBox();
}
}
function CreateBox()
{
var mousePos : Vector2 = Input.mousePosition;
if (Physics2D.OverlapCircle(mousePos.x, 0.2, LayerMask.foreground ))
{ } else {
//Depth you want the center of the object to be is z which I used zero
var boxPos : Vector3 = camera.ScreenToWorldPoint(Vector3(mousePos.x, mousePos.y, 10));
//I used the perfab box's rotation here but you can enter what you'd like as a euler using Quaternion.Euler(x,y,z)
Instantiate(boxes[boxCounter], boxPos, boxes[boxCounter].transform.rotation);
//This will increment if there are more boxes or reset to 0 if it is the last one.
if(boxCounter == boxes.length-1)
{
boxCounter = 0;
}else{
boxCounter ++;
}
}
}
```

I want to add a OverlapCircle function to avoid the creation of the object if there is already another one where I clicked. I don’t know exactly how this function works, any idea?

Thanks in advance !
