How to rotate Raycasts?

I need the distance from my object to the target hit, for another script. The problem is, that my object rotates while my raycast keeps facing down. How can i rotate my raycast or tell it to rotate along with the (parent)object?

Code (JavaScript):

1.  
2. #pragma strict
3.  
4.     var _distance : float;
5.     var _direction : Vector3;
6.  
7.     function FixedUpdate ()
8.     {
9.         var _hit:RaycastHit;
10.  
11.         _direction = Vector3.down;
12.         _direction = Quaternion.Euler(
13.         transform.parent.rotation.x,
14.         transform.parent.rotation.y,  
15.         transform.parent.rotation.z)
16.         * _direction;
17.        
18.         if (Physics.Raycast(transform.position, _direction, _hit, 10.0f))//Fall
19.         {
20.             Debug.Log(_hit);
21.             _distance = (this.transform.position.y) -
22.            (_hit.transform.position.y);
23.             SendMessageUpwards ("FrontDownToWorldToCharacterMove", _distance);
24.         }
25.         Debug.DrawRay (transform.position, _direction, Color.green);
26.     }
27.  

 

You could try using:

Code (CSharp):

1. _direction = -transform.up;

 

One way is to transform the direction vector from local object space to world space, which can be done with Transform.TransformDirection.

Code (JavaScript):

1. #pragma strict
2. var _distance : float;
3. var _direction : Vector3;
4. function FixedUpdate ()
5. {
6.     var _hit:RaycastHit;
7.      
8.       if (Physics.Raycast(transform.position, transform.TransformDirection(_direction), _hit, 10.0f)) //Fall
9.     {
10.          Debug.Log(_hit);
11.         _distance = (this.transform.position.y) - (_hit.transform.position.y);
12.         SendMessageUpwards ("FrontDownToWorldToCharacterMove", _distance);
13.     }
14.     Debug.DrawRay (transform.position, _direction, Color.green);
15. }
16.  

 

Thanks, that worked for me! Never thought I´d be that simple...
