Moving the units

Now that we have all the unit selection logic in place, we only need a couple more changes in the UnitSelectorComponent class to have it ready to move the units where we want on the map. The Update method, which is already defined in the UnitSelectorComponent class, needs one more validation that we are going to add at the end of the method, as we can see in the following code block, which will be used to check whether the right mouse button was released, using KeyCode.Mouse1:

private void Update()
{
  …

    Vector3 movePosition = GetMousePosition();
    MoveSelectedUnits(movePosition);
  }
}
