Make raycast ignore some objects.

I have read the whole thing there before and did it once again and I came to this code:

 var goal : Transform;
 var player : Transform;
 var source : Transform;
 
 var hit : RaycastHit;
 
 var layerPlayer : int = 8;
 var layerWalls : int = 9;
 var layerParticles : int = 10;
 
 var layermask1 : int = 1 << layerPlayer;
 var layermask2 : int = 1 << layerParticles;
 var layermask3 : int = 1 << layerWalls;
 
 var finalmask : int = layermask1 | layermask2 | layermask3;
 
 var chasingPlayer = false;
 
 function Update () {
 
     var ray = new Ray(source.transform.position, transform.TransformDirection(transform.forward));
     
     if(chasingPlayer == true){
     
         GetComponent(Nav$$anonymous$$eshAgent).destination = player.position;
         
         GetComponent(Nav$$anonymous$$eshAgent).speed = 7.5;
         
         Debug.Log("Chasing Player");
     
     }
     
     else if(Physics.Raycast(source.transform.position, transform.forward, hit, 300.0, finalmask)){
         
         if(hit.transform.tag == "Player"){
         
             GetComponent(Nav$$anonymous$$eshAgent).destination = player.position;
         
             chasingPlayer = true;
             
             Debug.Log("Found Player");
             
         }
         
         else{
         
             GetComponent(Nav$$anonymous$$eshAgent).destination = goal.position;
             
             Debug.Log("1");
         
         }
     
     }
     
     else{
     
         GetComponent(Nav$$anonymous$$eshAgent).destination = goal.position;
         
         Debug.Log("2");
     
     }
 
 }

But now it wont see the player. It doesn't see the player through walls though but now it doesn't see the player at all. Where am I wrong?

I don't spot anything wrong here. Does you player have a collider? Players can sometimes be composed of multiple game objects, is the game object with the collider set to the correct layer?

Note as a simpler solution to setting up your bitmask take a look at Eric5h5's solution using the Layer$$anonymous$$ask class (last entry on the page at the link I gave you).

Sorry, I put the wrong component as "source" so the ray went over the player and couldn't hit it. It seems to work now, thank you for the help!

If this solved your problem, click the checkmark next to the answer to mark it answered.

I can't use a different layer because as soon as I put the object on another layer it just falls through the level (presumably because it's not on the same as the floors and stuff that makes up the level).

So how do I make the raycast ignore the actual object in such a case?
