Hi,

If you only need to have a different car poping up and replace the current one, then you don't need to animate or do any camera mixing stuff.

Simply maintain a list of all the cars you want to be visible and maintain a variable that knows which car is currently visible. So if you have 4 car, the current car at start would be car 0.

the user press next or previous:

 1 hide the current car ( car x )
 2 select the next or previous car in your list ( car x +- 1 )
 3 show that one.

Does that make sense?

I have built a very basic c# component that will give you a starting point. Nothing fancy and 100% full proof, but the basic idea is here. If you have problems, let me know.

1: Simply create a c# script, and name it GOSelector. Edit it and paste the code below

2: drop it on any gameobject

3: select the component in the inspector

4: Define the number of items you want to have in GOList

5: drag and drop each one of them onto each items of GOList

6: optionnaly set a location for where you want them GameObject to be located.

Run. and press the left and right arrows to show the next or previous GameObject.

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

 public GameObject[] GOList;
 private int _currentID;

 public Transform GOLocationSpot;

 // Use this for initialization
 void Start () {

     // if GOLocation spot is not declare, will use our own transform instead.
     if (GOLocationSpot== null){
         GOLocationSpot = transform;
     }
     // start by hiding all
     foreach(GameObject _go in GOList){
         // we move it to the right location
         _go.transform.position = GOLocationSpot.position;
         // and we hide it for now.
         _go.active = false;
     }

     // now show the first
     ShowID(0);
 }

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


         if (Input.GetKeyDown(KeyCode.RightArrow)){
             ShowNext();
         }

         if (Input.GetKeyDown(KeyCode.LeftArrow)){
             ShowPrevious();
         }
 }

 void ShowNext(){
     ShowID(_currentID+1);
 }

 void ShowPrevious(){
     ShowID(_currentID-1);
 }

 void ShowID(int ID){

     if (ID&gt;=GOList.Length){
         ID = 0;
     }else if (ID&lt;0){
         ID = GOList.Length;
     }

     // hide the current
     GOList[_currentID].active = false;

     // now store the new ID as being the current
     _currentID = ID;
     GOList[_currentID].active = true;

 }// ShowID

Hope it helps,

Bye,

Jean
