This is a 2d top down game if it matters. I keep it flat.
I have an unknown number of sprites named („Unit_“+i)
When I click with the mouse on any location there is a method that checks the position on the grid. That position then goes to a new method that offsets the true hit so that it is at the same location as a Sprite Unit should be if it was there. The problem is, is it there, and if so, which one?
I have the location, and always will have it. What I don‘t have is the name on the location nor the object.
Any ideas?

public void CheackHit(Vector3 TrueHit)
{
    Vector3 _check_hit;
    _check_hit = TrueHit - _offset;

    //SearchForAnyObject.Transform.Position = _check_hit;
    //if anything found, return name
    //if nothing found, return nothing

}

The typical solution is to put colliders on your sprites and do a Physics2D.Raycast() or Physics2D.OverlapPoint() to see what is hit.
