Teleporting to outside of constraits

Hi all,

I have been working on a slender like game and I have come across a problem, my enemy seems to fly. This is not my script. Also the enemy teleports way outside the constraints I have assigned to him. There are three scripts attached to him, BasicSlenderTeleport, AI and EnemyScript. You may know these from the Slender guide by alucardj. Perhaps you could tell me the values I must assign to him in order for him to teleport in the area in that I have linked a picture to bellow. The map is 2000 x 2000

Here are the scripts :

AI

 /// created by MasterDevelopers ///
 #pragma strict
 
 var target : Transform;
 var rotSpeed = 3;
 
 var myTransform : Transform;
 
 function Awake()
 {
     myTransform = transform;
 }
 
 function Start () 
 {
     target = GameObject.FindWithTag("Player").transform;
 }
 
 function Update () 
 {
     myTransform.rotation = Quaternion.Slerp(myTransform.rotation,Quaternion.LookRotation(target.position - myTransform.position),rotSpeed * Time.deltaTime);
 }

BasicSlenderTeleport

 var player : Transform;      // the Object the player is controlling
 var spawnOrgin : Vector3;     // this will be the bottom right corner of a square we will use as the spawn area
 var maximum : Vector3;        // max distance in the x, y, and z direction the enemy can spawn
 var spawnRate : float;        // how often the enemy will respawn
 var distanceToPlayer : float; // how close the enemy has to be to the player to play music
 
 private var nearPlayer : boolean = false; // use this to stop the teleporting if near the player
 private var nextTeleport : float = 0.0f; // will keep track of when we to teleport next
 
 function Start ()
 {
     yield WaitForSeconds (141.2);
     nextTeleport = spawnRate;
 }
 
 function Update ()
 {
     if (!nearPlayer)     // only teleport if we are not close to the player
     {
         if (Time.time > nextTeleport)   // only teleport if enough time has passed
         {
             transform.position = Vector3( Random.Range(spawnOrgin.x, maximum.x), Random.Range(spawnOrgin.z, maximum.z) );   // teleport
             nextTeleport += spawnRate;    // update the next time to teleport
         }
     }
     if (Vector3.Distance(transform.position, player.position) <= distanceToPlayer)
     {
          if (audio && audio.clip && !audio.isPlaying)     // play the audio if it isn't playing
               audio.Play();
          nearPlayer = true;
     }
     else
     {
          if (audio)
             audio.Stop();
          nearPlayer = false;
     }
 }

Heres the image of the attached components:

Heres what where I want him to teleport to : http://www.mediafire.com/convkey/0281/z6vsfvrrvds00lmzg.jpg

I have also exported the scene as an object here it is : https://www.mediafire.com/?6frdqd8cwoseead

Apologies for the long question,

Thanks,

Eoin
