How to reset position on Vive ?

Hello,
I am making a plane game on Vive. I would like to have multiple point of views, in order to do that i changed the position of the CameraRig (too small to go on all the positions at once).
And I would like to reset the position of the eye camera exactly on a dummy (to be sure the head is where I want). But I don't know how to do it.

Code (CSharp):

1. if (Input.GetKeyUp(KeyCode.M))
2.         {
3.             CameraRigVR.transform.parent = Placecockpit.transform;
4.             CameraRigVR.transform.position = Placecockpit.transform.position;
5.          
6.             Valve.VR.OpenVR.System.ResetSeatedZeroPose();
7.         }

 

Did you try InputTracking.Recenter already?

 

Yes can't manage to make it work ether, I fell like I miss something, is this function suppose to place the camera at is parent position? How does he know which camera, and parent, it is ?

 

+This one is for Oculus, not Vive

 

I spent a lot of time looking for an answer on this. Eventually wrote this script which took care of it to my liking.

This script will allow a reset of the SteamVR camera rig to align with a transform representing the desired head position in the scene. Attach to any GameObject in the scene. Useful for seated experiences like cockpits.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class ResetSeatedPosition : MonoBehaviour {
4.  
5.     [Tooltip("Desired head position of player when seated")]
6.     public Transform desiredHeadPosition;
7.     private Transform steamCamera;
8.     private Transform steamController;
9.  
10.     // Update is called once per frame
11.     void Update () {
12.  
13.         if (Input.GetKeyDown(KeyCode.Space))
14.         {
15.             if (desiredHeadPosition != null)
16.             {
17.                 ResetSeatedPos(desiredHeadPosition);
18.             }
19.             else
20.             {
21.                 Debug.Log("Target Transform required. Assign in inspector.");
22.             }
23.        
24.         }
25.     }
26.  
27.     private void ResetSeatedPos(Transform desiredHeadPos){
28.  
29.         //find VR Camera and CameraRig transforms in scene
30.         steamCamera = FindObjectOfType<SteamVR_Camera>().gameObject.transform;  
31.         steamController = FindObjectOfType<SteamVR_ControllerManager>().transform;
32.  
33.         if ((steamCamera != null) && (steamController != null))
34.             {
35.             //{first rotation}
36.                 //get current head heading in scene
37.                 //(y-only, to avoid tilting the floor)
38.                 float offsetAngle = steamCamera.rotation.eulerAngles.y;
39.                 //now rotate CameraRig in opposite direction to compensate
40.                 steamController.Rotate(0f, -offsetAngle, 0f);
41.  
42.             //{now position}
43.                 //calculate postional offset between CameraRig and Camera
44.                 Vector3 offsetPos = steamCamera.position - steamController.position;
45.                 //reposition CameraRig to desired position minus offset
46.                 steamController.position = (desiredHeadPos.position - offsetPos);
47.  
48.                 Debug.Log("Seat recentered!");
49.             }
50.         else
51.             {
52.                 Debug.Log("Error: SteamVR objects not found!");
53.             }
54.     }
55. }
56.  

Turned out to be simpler than I expected. Hope it can save someone else the time!

Cheers,

Gerry
