Hello all. This is my first post on the site, and I'm having some problems with Yield WaitForSeconds. I'm just plain confused and know nothing really about this. I have a script that uses iTween to switch camera positions from first person to third person. I then have another script that deactivates my first person model and activates my third person one. Switching from first to third person works fine, but when I switch back to third person, the first person and third person models activate before the camera zooms in, and I am trying to get it to wait by using WaitForSeconds. Could someone help me? Here's my script so far:

using UnityEngine;
using System.Collections;



public class ModelActive : MonoBehaviour {

    public GameObject Model;

    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {

       if(Input.GetKeyUp(KeyCode.Tab)) {

         Model.SetActiveRecursively(true);

       }

       if(Input.GetKeyUp(KeyCode.LeftAlt)) {

         Model.SetActiveRecursively(false);

       }

    }
}
