    Problem: I need to be able to store and recall the position (and direction) of a camera.

    Setup: I am using MouseOrbitZoom(MaxCamera) script to observe a 3d object. I want the user to have the ability to store the camera position and angle and continue to move around the scene. Then, at a later point, they have the ability to recall the stored camera angle and return to that position.

    Any sample code, or examples would be greatly appreciated.

    Thank you in advance, Fred

    just create a class to save the position :

    Code (csharp):
    1. public class CamPosSave {
    2.  
    3.     private static Transform mycampos;
    4.     public static Transform MyCamPos {
    5.         get { return mycampos; }
    6.         set { mycampos = value; }
    7.     }
    8. }
    to save :
    CamPosSave.MyCamPos = Camera.main.transform;
    to retrieve :
    Camera.main.transform = CamPosSave.MyCamPos;

    it's untested but should work, you don't need to attach the class to a gameobject.

    actualy you need to do the position and rotation seperated :

    Code (csharp):
    1. using UnityEngine;
    2.  
    3. public class CamPosSave {
    4.  
    5.     private static Vector3 myCamPos;
    6.     public static Vector3 MyCamPos {
    7.         get { return myCamPos; }
    8.         set { myCamPos = value; }
    9.     }
    10.  
    11.     private static Vector3 mycamrot;
    12.     public static Vector3 MyCamRot {
    13.         get { return mycamrot; }
    14.         set { mycamrot = value; }
    15.     }
    16. }
    Code (csharp):
    1.     void OnGUI ()
    2.     {
    3.         if (GUILayout.Button("Save"))
    4.         {
    5.             CamPosSave.MyCamPos = GameObject.Find("testcube").transform.position;
    6.             CamPosSave.MyCamRot = GameObject.Find("testcube").transform.eulerAngles;
    7.         }
    8.         if (GUILayout.Button("Restore"))
    9.         {
    10.             GameObject.Find("testcube").transform.position = CamPosSave.MyCamPos;
    11.             GameObject.Find("testcube").transform.eulerAngles = CamPosSave.MyCamRot;
    12.         }
    13.     }
