  1 | /*
  2 | This script was developed by Jupp Otto. It's free to use and there are no restrictions in modification.
  3 | If there are any questions you can send me an Email: juppotto3@gmail.com
  4 | This script moves your player automatically in the direction he is looking at. You can 
  5 | activate the autowalk function by pull the cardboard trigger, by define a threshold angle 
  6 | or combine both by selecting both of these options.
  7 | The threshold is an value in degree between 0° and 90°. So for example the threshold is 
  8 | 30°, the player will move when he is looking 31° down to the bottom and he will not move 
  9 | when the player is looking 29° down to the bottom. This script can easally be configured
 10 | in the Unity Inspector. 
 11 | How to get started with this script?: 
 12 | 0. haven't the Google VR SDK yet, follow this guide https://developers.google.com/vr/unity/get-started
 13 | 1. Import the exampple package downloaded in step 0 (GoogleVRForUnity.unitypackage).
 14 | 2. Load the GVRDemo scene.
 15 | 3. Attach a Rigidbody to the "Player" GameObject.
 16 | 4. Freeze X, Y and Z Rotation of the Rgidbody in the inspector. 
 17 | 5. Attach a Capsule Collider to the "Player" GameObject.
 18 | 6. Attach the Autowalk script to the "Player" GameObject.
 19 | 7. Configure the Script in the insector for example: 
 20 |       - walk when triggered   = true 
 21 |       - speed                 = 3  
 22 | 8. Make sure your ground have a collider on it. (Otherwise you will fall through it)
 23 | 9. Start the scene and have fun!
