Raycast2D errors.

Hey guys i'm working on the "Fun with lasers" live training archive by mike gieg. However i am doing it in 2d for my game. this is what i have.

Code (CSharp):

1.  
2.             line1.enabled = true;
3.             line2.enabled = true;
4.  
5.             Ray2D ray1 = new Ray2D(line1.transform.position, line1.transform.up);
6.             Ray2D ray2 = new Ray2D(line2.transform.position, line2.transform.up);
7.             RaycastHit2D hit1;
8.             RaycastHit2D hit2;
9.  
10.             line1.SetPosition (0, ray1.origin);
11.             if(Physics2D.Raycast(ray1, out hit1, 50f))
12.                 line1.SetPosition(1, hit1.point);
13.             else
14.                 line1.SetPosition (1, ray1.GetPoint(50f));
15.  
16.             line2.SetPosition (0, ray2.origin);
17.             if(Physics2D.Raycast (ray2, out hit2, 50f))
18.                 line2.SetPosition(1, hit2.point);
19.             else
20.                 line2.SetPosition (1, ray2.GetPoint(50f));

i have an error on the 2 if statements that says i can't convert a ray2D to a vector2D.

 

Physics.Raycast(...) has an overload function with these parameters:

Physics2D.Raycast(...) only has a single function with these parameters:

You are going to have to use the origin/direction (i.e. the parameters you're passing to form the ray) rather than a ray in the raycast.

 

Thanks man i really really appreciate it.
