Visualizing an Object's Front Arc Line of Sight

Hello,
I'm trying to draw an object's front arc line of sight for debugging purposes.
I'm using the following code.

Code (csharp):

1.  
2. void Update ()
3.     {
4.        
5.         Vector3 losRight = transform.TransformDirection(Quaternion.Euler(0, 45, 0) * transform.forward)*5;
6.         Vector3 losLeft = transform.TransformDirection(Quaternion.Euler(0, -45, 0) * transform.forward)*5;
7.         Debug.DrawRay(transform.position, losRight, Color.green);
8.         Debug.DrawRay(transform.position, losLeft, Color.green);
9.    
10.     }
11.  

I'm getting the correct result, pictured below, until the object rotates, at which point the rays begin to skew.



Any Idea how I can keep this front arc visual consistent?

I was also trying to implement the Handles.DrawSolidArc I found here, but with no luck. I know even less about javascript than I do about C# (fledgling programmer).
Any help would be greatly appreciated.
Thank You!

 

Code (csharp):

1. void Update()
2. {
3.     float distance = 5f;
4.     Debug.DrawRay(transform.position, (transform.forward + transform.right) * distance, Color.green);
5.     Debug.DrawRay(transform.position, (transform.forward - transform.right) * distance, Color.green);
6. }

 

Here is an example using the Handles.DrawSolidArc in C#. First you must make a folder called 'Editor' and place the following script in it:

Code (csharp):

1.  
2. using UnityEngine;
3. using UnityEditor;
4.  
5. [CustomEditor(typeof(SolidArcExample))]
6. public class DrawSolidArc : Editor
7. {
8.  
9.     void OnSceneGUI()
10.     {
11.         SolidArcExample myTarget = (SolidArcExample)target;
12.  
13.         Handles.color = new Color(1f, 1f, 1f, 0.2f);
14.  
15.         Handles.DrawSolidArc(myTarget.transform.position,
16.             myTarget.transform.up,
17.             -myTarget.transform.right,
18.             180,
19.             myTarget.shieldArea);
20.  
21.         Handles.color = Color.white;
22.  
23.         myTarget.shieldArea = Handles.ScaleValueHandle(myTarget.shieldArea,
24.             myTarget.transform.position + myTarget.transform.forward * myTarget.shieldArea,
25.             myTarget.transform.rotation,
26.             1f,
27.             Handles.ConeCap,
28.             1f);
29.     }
30. }

You must then make the following script and place it as a component on the object that you want to have the arc.

Code (csharp):

1.  
2. using UnityEngine;
3.  
4. public class SolidArcExample : MonoBehaviour
5. {
6.  
7.     public float shieldArea = 5f;
8. }
9.
