Enemy Angle?

Hi! I'm trying to test some enemy detection AI, but I have a slight problem. It works for the most part except the enemy cannot detect if the player is in its front line of view. How can I do this:

Code (csharp):

1.  
2. var detectRadius : float = 30.0;
3. var viewSpread : float = 40.0;
4. function Update        (){
5.     //Detect Radius
6.     if(Vector3.Distance(player.position, transform.position) > detectRadius){
7.         Debug.Log("The Enemy cannot see you...");
8.     }
9.     if(Vector3.Distance(player.position, transform.position) < detectRadius){
10.         Debug.Log("Be careful! You're close to an enemy!");
11.         if(//The player is in enemy sights...){
12.             Debug.Log("You've been spotted! RUN!");
13.         }
14.     }
15. }
16. function OnDrawGizmosSelected    (){
17.     //Detect Radius
18.     Gizmos.color = Color.yellow;
19.     Gizmos.DrawWireSphere(transform.position,detectRadius);
20.     //View Radius
21.     Gizmos.color = Color.magenta;
22.     Gizmos.DrawRay(transform.position,Quaternion.AngleAxis(viewSpread, transform.up) * transform.forward * detectRadius);
23.     Gizmos.DrawRay(transform.position,Quaternion.AngleAxis(-viewSpread, transform.up) * transform.forward * detectRadius);
24. }
25.  

This is how the gizmos draw it. How can I detect if the player is between the pink lines:

 

Use Vector3.Angle() http://docs.unity3d.com/ScriptReference/Vector3.Angle.html

 

I guess a little more research could've helped.lol Anyways, it's SOLVED:

Code (csharp):

1.  
2.         if(Vector3.Angle(player.position - transform.position, transform.forward) < viewSpread){
3.             Debug.Log("You've been spotted! RUN!");
4.         }
5.  

Thanks!
