Oh it didn't take my script with, here is the script that i made:

pragma strict

var target : Transform; var look : boolean = false;

function OnTriggerEnter (other : Collider) { if(other.tag == "Wall")

GameObject.Find( "First Person Controller" ).GetComponent(FPSInputController).enabled = false;

GameObject.Find( "First Person Controller" ).GetComponent(CharacterMotor).enabled = false;

GameObject.Find( "First Person Controller" ).GetComponent(MouseLook).enabled = false;

GameObject.Find( "Main Camera" ).GetComponent(MouseLook).enabled = false;

look = true;

yield(WaitForSeconds(5));

GameObject.Find( "First Person Controller" ).GetComponent(FPSInputController).enabled = true;

GameObject.Find( "First Person Controller" ).GetComponent(CharacterMotor).enabled = true;

GameObject.Find( "First Person Controller" ).GetComponent(MouseLook).enabled = true;

GameObject.Find( "Main Camera" ).GetComponent(MouseLook).enabled = true;

look = false;

}

function Update () {

if(look == true)

transform.LookAt(target);

}

 var target             : Transform; 
     var look             : boolean = false;
     var fpsInput         : FPSInputController;
     var character$$anonymous$$otor     : Character$$anonymous$$otor;

     var mouseLook2        : $$anonymous$$ouseLook;
     
     function Start() {
         fpsInput         = GameObject.Find("First Person Controller").GetComponent(FPSInputController);
         character$$anonymous$$otor     = GameObject.Find("First Person Controller").GetComponent(Character$$anonymous$$otor);
         mouseLook         = GameObject.Find("First Person Controller").GetComponent($$anonymous$$ouseLook);
         mouseLook2         = GameObject.Find("$$anonymous$$ain Camera").GetComponent($$anonymous$$ouseLook);
     }
     function OnTriggerEnter (other : Collider) {
         if(other.tag == "Wall") {
             DisableComponents();
         }
     }
     function DisableComponents() {
         fpsInput.enabled = false;

         look = true;
         yield WaitForSeconds(5);
         EnableComponents();
         look = false;
     }
     function EnableComponents() {
         fpsInput.enabled = true;
         character$$anonymous$$otor.enabled = true;
         mouseLook.enabled = true;
         mouseLook2.enabled = true;
     }
     function Update () {
         if(look == true) {
             transform.LookAt(target);
         }
     }
