* Create a box or other 3D Object:
  * make sure this object has a "**Box Collider**" set to “**IsTrigger**”.
* Add the “**PhoneTrigger**” script to that 3D object and add the phone 3D model to the inspector slot named “**Phone Model Object**”. 
* Make sure to add the Trigger object to the "**Controller**" script and tick the boolean to activate
* Then set an input key in the "**InputManager**". Default set to “E”!
