Physics.Raycast (8698)

[system]

var target : Transform; //the enemy's target
var moveSpeed = 3; //move speed
var rotationSpeed = 3; //speed of turning
var hunt : boolean = false;
var myTransform : Transform; //current transform data of this enemy
var distance : int;

function Awake()
{
    myTransform = transform; //cache transform data for easy access/preformance
}

function Start()
{
     target = GameObject.FindWithTag("Player").transform; //target the player

}

can somebody tell me how i can make the Raycast work in a way, that my hunter only hunts me if nothing is between us???

function Update () {

    dist = (transform.position - target.position).magnitude;
    if(dist < distance){
        hunt = true;
    }
    else{
        hunt = false;
    }
    var inSight = true;
    if(Physics.Raycast(transform.position,inSight, 5)){
        inSight = false; 
    }

    if(hunt == true && inSight == true){
    //rotate to look at the player
    myTransform.rotation = Quaternion.Slerp(myTransform.rotation,
    Quaternion.LookRotation(target.position - myTransform.position), rotationSpeed*Time.deltaTime);

    //move towards the player
    myTransform.position += myTransform.forward * moveSpeed * Time.deltaTime;
    }

}

You have to understand how the function works. It returns true if anything is intersecting the line that's cast, including the player character. What you need to do is add a second clause that can distinguish between player and non-player objects. You do that using the raycast hit properties.

e.g.

var hit : RaycastHit;
var direction : Vector3;

direction = target.position - transform.position;

if (Physics.Raycast (transform.position, direction, hit)) {
    if(hit.collider.CompareTag("Player")){
       // Nothing between the us and the player object
       // Chase the player
    }else{
       // Something blocking line of sight
       // Do something else
    }
    // Show in the editor the ray
    Debug.DrawLine (transform.position, hit.point);
}

Read the documents carefully about which parameters the various versions use:

function Raycast (origin : Vector3, direction : Vector3, out hitInfo : RaycastHit, distance : float = Mathf.Infinity, layerMask : int = kDefaultRaycastLayers) : bool

EDIT:

use debug draw line to show exactly where the ray is being cast

alright... so this is cind of working, but I have a big prob, even if there is clearly a Object in the way of my hunter the var InSight is till true.... why is it not false even if a Object is in the way?? here is the Raycast loop like it is right now:

var hit : RaycastHit;
    var direction : Vector3;
    direction =target.position - transform.position;
    if(Physics.Raycast(transform.position , direction, hit)) {
        if(hit == GameObject.FindWithTag("Player")) {
            var InSight = hit.distance;
