RayCastHit2d

Hi, I am trying to go through the free tutorial on the unity webpage.
I have this code that is from the Rogue Tutorial that doesnt make sense to me.
Apparently Physics.LineCast returns a Bool.(According to Unity docs)
So how come they do this?
RAYCASTHIT2d is not a bool.

Code (CSharp):

1. protected bool Move (int xDir, int yDir, out RaycastHit2D hit)
2.        {
3.      
4.             hit = Physics2D.Linecast (start, end, blockingLayer);
5.        
6.            //Re-enable boxCollider after linecast
7.             boxCollider.enabled = true;
8.        
9.            //Check if anything was hit
10.             if(hit.transform == null)
11.            {
12.          
13.            }
14.             return false;
15.        }

iT'S from this tutorial

I found the answer.
Physics.Linecast returns a bool
Physics2d.linecast returns a raycasthit2d

 

Yeah, good catch... there's a ton of similiar "close but not quite exact" things you have to watch out for when working with Unity physics, since it's super easy to be looking at a 3D physics function and thinking you're looking at a 2D physics function!
