How to do the movement of a player while using hand tracking in the oculus quest? Anyone have done Player movement?Have tried to move OVRCameraRig with joystick four-button forward/backward/left/right. OVRCameraRig moves perfectly but issue is both HAND Models are not moving with OVRCameraRig. Tried to Put "Hands" game object as a parent of OVRCameraRig but no luckDoes anyone have an idea?

Don't know if this solution is thebest, but it works.Add this code to the RayTool.cs code toget the HandsAnchors inside the class: public GameObject handAnchorLeft,handAnchorRight;public void Awake() { handAnchorLeft = GameObject.Find("LeftHandAnchor"); handAnchorRight = GameObject.Find("RightControllerAnchor"); }As well change the GetRayCastOrigin()function inside the RayTool.cs like in the following lines:private Vector3 GetRayCastOrigin(){ if (IsRightHandedTool) {returnhandAnchorRight.transform.position + MINIMUM_RAY_CAST_DISTANCE * handAnchorRight.transform.forward;} else {returnhandAnchorLeft.transform.position + MINIMUM_RAY_CAST_DISTANCE * handAnchorLeft.transform.forward;}}In the script RayToolView.cs go to theUpdate() function and change "var myPosition =" to:var myPosition =InteractableTool.IsRightHandedTool ?transform.parent.GetComponent<RayTool>().handAnchorRight.transform.position:transform.parent.GetComponent<RayTool>().handAnchorLeft.transform.position;This should do the work. The rays arenow following the positions of the hands if you move the character.

modhdhruv said: Tried to change in UpdatePose() HandSkeleton.cs.transform.position = pose.RootPose.Position.FromFlippedZVector3f() + OVRCameraRig.transform.localPosition;- Hand moving perfectly with OVRCameraRig.Now how to move OVRCameraRig in the center camera direction is looking?Note that adding positions this way does not account for local rotated translation of the OVRCameraRig, which InverseTransformPoint does do. You can test this by rotating the OVRCameraRig 90 degrees on the Y axis. Your hands will appear left/right next to you if you add the positions, and still in front of you when using InverseTransformPoint. Note that the returned position is then also affected by scale, which is a good thing in this case.Moving the OVRCameraRig in the direction the camera is looking - can be done by calculating a flat rotation and translating forward in that direction, doing something like this:float speed = 2.0f;Transform ovrCameraRig;void Update () {Quaternion headRotationFlat = Quaternion.Euler(0, Camera.main.transform.eulerAngles.y, 0);ovrCameraRig.transform.Translate((headRotationFlat * Vector3.forward) * speed * Time.deltaTime, Space.World);}But there are many alternatives to this. Try and see which solution works best for your application. Maybe yours is better suited to incorporate teleportation locomotion for example? You can also try and check out the new Unity XR Interaction Toolkit. Can't link it here, but try and google it, you'll find it really quick. It's also in the Unity Package Manager. It allows you to use some really nifty 'drag-and-drop' teleportation, interaction and more XR-based components.

Thanks, @Stimmits for your efforts. :) Perfectly moving as I expecting. Have you tried OVRPlayerController instead of OVRCameraRig?When using PlayerController have an issue regarding PanelHMDFollower.cs script. I'm using the PanelHMDFollower script for a button to keep nearby OVRCameraRig. But when use PlayerController it moves automatically in any direction when scene load.

I'm using OVRCameraRig as part of my own player rig setup. But as I mentioned, there are many alternatives to moving your player around. I'm glad you figured it out.Btw; when you are planning to use pinch gestures or pointer/raycast functionality for the hand-tracking, you have to translate the Pointer position and rotation to use the player rig reference location as well in your situation.It's this part in Hand.cs:// this part:_pointer.PointerPosition = _currentState.PointerPose.Position.FromFlippedZVector3f();_pointer.PointerOrientation = _currentState.PointerPose.Orientation.FromFlippedZQuatf();// change to:_pointer.PointerPosition = transform.TransformPoint(_currentState.PointerPose.Position.FromFlippedZVector3f());Quaternion rotation = _currentState.PointerPose.Orientation.FromFlippedZQuatf();_pointer.PointerOrientation = Quaternion.LookRotation(transform.TransformDirection(rotation * Vector3.forward), transform.TransformDirection(rotation * Vector3.up));I hope @Oculus fixes this world to local hassle soon in their SDK, otherwise we'll find ourselves changing all these lines over and over again when they push an update to the SDK.

Same issue here.. the moment you move the OVRCameraRig away from 0,0,0 the hands stay at the original location. It's pre-release, but still, seems like that should not be that hard to fix. I'll have a look

Look for the file: HandSkeleton.cs, change line 145 to use localPosition

// line 145: transform.position = pose.RootPose.Position.FromFlippedZVector3f();
transform.localPosition = pose.RootPose.Position.FromFlippedZVector3f();

It's not working properly. Can you help me solve this problem again?Thanks

What's not working.. please be a bit more specific. I found some issues when you're starting outside of 0,0,0 but if you start there you can transport elsewhere and still have your hands working.

The hand can be used normally. It can move to a position other than 0,0,0, but the position of the ray does not follow the position of the hand.The ray is still emitted from 0,0,0.

Don't know if this solution is the
best, but it works.
Add this code to the RayTool.cs code to
get the HandsAnchors inside the class:

public GameObject handAnchorLeft,
handAnchorRight;
public void Awake()
        {

handAnchorLeft = GameObject.Find("LeftHandAnchor");

handAnchorRight = GameObject.Find("RightControllerAnchor");
        }

As well change the GetRayCastOrigin()
function inside the RayTool.cs like in the following lines:

private Vector3 GetRayCastOrigin(){
     if (IsRightHandedTool)
     {return
handAnchorRight.transform.position + MINIMUM_RAY_CAST_DISTANCE *
                 handAnchorRight.transform.forward;}
     else
    {return
handAnchorLeft.transform.position + MINIMUM_RAY_CAST_DISTANCE *

                 handAnchorLeft.transform.forward;}
}

In the script RayToolView.cs go to the
Update() function and change "var myPosition =" to:

var myPosition =
InteractableTool.IsRightHandedTool ?
transform.parent.GetComponent<RayTool>().handAnchorRight.transform.position
:
transform.parent.GetComponent<RayTool>().handAnchorLeft.transform.position;

This should do the work. The rays are
now following the positions of the hands if you move the character.

I'm trying to move OVRCameraRig forward/back/left/right using hand button interaction. The issue is when OVRCameraRig moves forward, Hands do not move with OVRCameraRig. Does anyone have solution for this?

Try to change position in HandSkeleton.cs. But not working.

Ah amazing, this worked. I also had to change the rotation to use the localRotation. Thank you very much!

This only works when you have the skeleton hands active, for the mesh hands change HandMesh.cs to the following:

// line 119: vertices = transform.InverseTransformPoint(mesh.VertexPositions.FromFlippedZVector3f());

Also, make sure that your hands are parented under the OVRCameraRig.

Tried to change in UpdatePose() HandSkeleton.cs.
transform.position = pose.RootPose.Position.FromFlippedZVector3f() + OVRCameraRig.transform.localPosition; - Hand moving perfectly with OVRCameraRig.
Now how to move OVRCameraRig in the center camera direction is looking?
