On Trigger , stop player from moving and look at X

[system]

hello guys
I want to do exactly what is in the subject. like a guy is standing in the middle. and I put a trigger on him. I want that when main camera enter that trigger , stop scripts ( fps walker & fps look) and then camera look at a object. I used the following scripts but it doesn’t work. can you guys edit it to the one that I want? (“Durbin Asli” is my main camera")-- I just Added look at script but it doesn’t work – then I want that wait for 5 sec then everything back to normal" – I know the codes But IDK how to put them together. for example I know look at command … but I don’t know what should I do to say “main camera… look at … target” … if you guys help me and edit this for me you’d be a great help for me!

using UnityEngine;
using System.Collections;

public class Treeger : MonoBehaviour {

public Transform target;
public GameObject MC;

void Start ()
{
    MC = GameObject.Find("Durbin Asli");
}


void Update () {

}
void OnTriggerEnter()
{
    CharacterControl.tree--;
    Destroy(gameObject);
    MC.transform.LookAt(target);
}

}

It must disable the character scripts, control the camera, then reenable the scrips. Since the camera may have its own scripts, you must disable them too - the First Person Controller, for instance, uses MouseLook.cs in the camera and in the character.

A simple alternative is to use a routine that disables or enables all scripts in the character (whose collider is informed in OnTriggerEnter) and in the camera (which is informed in MC):

using UnityEngine; 
using System.Collections;
public class Treeger : MonoBehaviour {

public GameObject MC;
public Transform target;
public float timeLook = 0.5f;
public float timeWait = 4f;

void Start (){
    MC = GameObject.Find("Durbin Asli");
}

bool looking = false;

IEnumerator OnTriggerEnter (Collider obj){ // make OnTriggerEnter a coroutine
	if (looking) return; // does nothing if already looking  
	looking = true; // I'm going to look
	EnableScripts(obj.transform, false); // disable all obj scripts
	EnableScripts(MC.transform, false); // disable all camera scripts
	Quaternion rot1 = MC.transform.rotation; // save initial direction
	// define target direction in rot2
	Quaternion rot2 = Quaternion.LookRotation(target.position-MC.transform.position, Vector3.up); 
	for (float t = 0f; t < 1f;){ // look at target in timeLook seconds
		t += Time.deltaTime / timeLook;
		MC.transform.rotation = Quaternion.Lerp(rot1, rot2, t);
		yield return null;
	}
	yield return new WaitForSeconds(timeWait); // wait timeWait seconds
	for (float t = 0f; t < 1f;){ // return to original direction in timeLook seconds
		t += Time.deltaTime / timeLook;
		MC.transform.rotation = Quaternion.Lerp(rot2, rot1, t);
		yield return null;
	}
	EnableScripts(obj.transform, true); // enable obj scripts
	EnableScripts(MC.transform, true); // enable camera scripts
	looking = false; // finished looking
}

void EnableScripts (Transform owner, bool onOff){

	MonoBehaviour[] scripts;

	scripts = owner.GetComponents(); // get all scripts in owner
	foreach (MonoBehaviour script in scripts){
		script.enabled = onOff; // enable or disable all scripts
	}
}
}
