Unity - Move the camera

README

**Set up the camera**

* Import the VR Samples Asset ( https://www.assetstore.unity3d.com/en/#!/content/51519 )
* Open the scene InteractiveItem ( Assets/VRSampleScenes/Scenes/Examples/InteractiveItem )
* Selelct the MainCamera Object and copy it ( right click - copy )
* Open your scene and paste it ( right click- paste )
* Create one Empty object ( name it CameraWrapper )
* Drag the Main Camera as child of CameraWrapper
* On Camera Wrapper, Add a Componenent : the script MoveToward ( code bellow )

**Set up a target object**

* Create an object the Camera will pane to. I call it Target. (just a cube will do)
* On Target, be sure to have a Component Collider
* On Target, Add a Componenent : the script VRInteractiveItem ( from VR Samples Asset )
* On Target, Add a Componenent : the script DragObject ( code bellow )
* On Target, Add a Componenent : the script FadeNLoad ( code bellow )

* On Target, In DragObject Component, Drag and Drop Target in Interactibe Item attribute
* On Target, In DragObject Component, Drag and Drop Target in Target attribute
* On Target, In DragObject Component, Drag and Drop CameraWrapper in Source Item attribute

* On Target, In FadeNLoad Component, Drag and Drop Target in Interactibe Item attribute
* On Target, In FadeNLoad Component, Drag and Drop MainCamera in Camera To Fade attribute **(Not the wrapper, the camera itself)**
* On Target, In FadeNLoad Component, Write the name of a scene in Scene to Load attribute

**Action**
* Play your scene
* Point the target object
* Click on the remote main button
* You must move toward the target object then fade out to black, then fade in in your new scene

DragObject.cs

using UnityEngine;

FadeNLoad.cs

using UnityEngine;

		private void HandleClick()
		{
			StartCoroutine (CallFade());
		}

		private void HandleDoubleClick()
		{
		}

		private IEnumerator CallFade()
		{
			// If the camera is already fading, ignore.
			if (m_CameraToFade.IsFading)
				yield break;
			// Wait for the camera to fade out.
			yield return StartCoroutine(m_CameraToFade.BeginFadeOut(true));
			// Load the level.
			SceneManager.LoadScene(m_SceneToLoad, LoadSceneMode.Single);

MoveToward.cs

using UnityEngine;
using System.Collections;

public class MoveToward : MonoBehaviour {
	[SerializeField] public Transform target;
	[SerializeField] public float speed;
	[SerializeField] public bool come;

	void Update () {
		if (come) { //a object drag the cam
			float step = speed * Time.deltaTime;
			Vector3 nextPosition = Vector3.MoveTowards(transform.position, target.position, step);
			// if cam is arrived, stop moving
			if (nextPosition == transform.position) {
				come = false;
			} else {
				transform.position = nextPosition;
			}
		}
