How to reset position on Vive ?

Unity Engine
1

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.

if (Input.GetKeyUp(KeyCode.M))
        {
            CameraRigVR.transform.parent = Placecockpit.transform;
            CameraRigVR.transform.position = Placecockpit.transform.position;
         
            Valve.VR.OpenVR.System.ResetSeatedZeroPose();
        }

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.

using UnityEngine;

public class ResetSeatedPosition : MonoBehaviour {

    [Tooltip("Desired head position of player when seated")]
    public Transform desiredHeadPosition;
    private Transform steamCamera;
    private Transform steamController;

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

        if (Input.GetKeyDown(KeyCode.Space))
        {
            if (desiredHeadPosition != null)
            {
                ResetSeatedPos(desiredHeadPosition);
            }
            else
            {
                Debug.Log("Target Transform required. Assign in inspector.");
            }
        
        }
    }

    private void ResetSeatedPos(Transform desiredHeadPos){

        //find VR Camera and CameraRig transforms in scene
        steamCamera = FindObjectOfType<SteamVR_Camera>().gameObject.transform;   
        steamController = FindObjectOfType<SteamVR_ControllerManager>().transform;

        if ((steamCamera != null) && (steamController != null))
            {
            //{first rotation}
                //get current head heading in scene
                //(y-only, to avoid tilting the floor)
                float offsetAngle = steamCamera.rotation.eulerAngles.y;
                //now rotate CameraRig in opposite direction to compensate
                steamController.Rotate(0f, -offsetAngle, 0f);

            //{now position}
                //calculate postional offset between CameraRig and Camera
                Vector3 offsetPos = steamCamera.position - steamController.position;
                //reposition CameraRig to desired position minus offset
                steamController.position = (desiredHeadPos.position - offsetPos);

                Debug.Log("Seat recentered!");
            }
        else
            {
                Debug.Log("Error: SteamVR objects not found!");
            }
    }
}

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

Cheers,

Gerry
