This creates a lot of confusion, especially for beginners. Both ARCore and ARKit should "just work" out of the box on this sample repo.

Also, there should be a warning when using ARFoundation and building for Android without this present; right now you just get a black screen.

I'm building a game where the selection of one thing needs to give you another e.g. selecting a quiver puts an arrow in your hand. The ForceSelect method in XRInteractionManager is a great way of doing this, but it is marked as "internal" not "public" and no public accessor has been made available. If there's an intended way of doing this please let me know, but if that could be made public that would be the easiest.

Hide Controller On Select didn't seem to do anything, and I can't find any implementation for it outside of the editor class for XRRayInteractor.

I've compiled WorldInteraction demo scene for Oculus Quest and it works well. I can grab XRGrabbables but after pressing the system button in Oculus Touch to pause the app and resuming it back, I stop being able to grab these objects.

Steps to reproduce:

1. Play WorldInteraction in Oculus Quest
2. Grab an object
3. Pause the app
4. Resume the app
5. Try grabbing objects again

Me and my colleague are having this issue. I'd like to know if this is a known problem.

I can't seem to get the example projects to run as expected:

WorldInteractionDemo:

• My player levitates 2 meters above the starting area
• I can't teleport to anything. A blue ray, indicate that I should be able to teleport, but nothing happens regardless of what I push on the controllers

I am using an Oculus Rift S. All Oculus drivers are fully updated.
I have tried both Unity 2019.3.0f6 and 2019.3.6f1.
I already run the guardian setup, but that did nothing for the levitate issue.

To reproduce:

• tap to add a cube
• tap to select the cube
• two-finger scale it down (move fingers closer to each other - keep the fingers on screen)
• move the fingers away from each other

Expected: cube scales up again
Actual: cube stays small, gesture needs to be restarted to have an effect

Same happens with scale up.

Hello! Is there a way to set the default size for the AR Scale Interactable?
Currently it seems to set as the max value. I'd prefer it to be set at a mid value, between min and max. So that the user can both scale up and down the object from the start. It also eases placement of the object as it is supposed to be scaled up quite drastically.

Most of the other VR libraries allow the user to 'grab' at the edge of an object (for example, a cube) and move and rotate it from there, rather than that cube snapping to the centre of the controller and rotating instantly.

Think a game of Jenga - you'd carefully grab at the edge of the block and pull it out; or even pulling one cube out from under another. That's currently not possible with this (otherwise pretty awesome) XR library, as far as I can tell. Unless I've missed something obvious?

I did see the ability to set a grab transform, but that's not really the same at all.

Deleting selected object in the AR-scene causes errors, which make placing of the new objects or selecting already existing objects impossible. There is no possibility to disable selection after deleting the object (what would probably fix "NullReferenceException").

Hi there!
I am working on a game that uses the XR Interaction Toolkit.
I have implemented walk movement using a PlayerController, but haven't yet added a teleportation option for people who are susceptible to VR sickness. The reason for this is that I would like the teleportation to occur when pressing a custom button, for example, (A) on an Index or Oculus controller. I have used CommonUsages before and know that you can get button events, but how can I translate that into a teleportation trigger? Currently, the only options are OnSelectEnter/Exit and OnActivate/Deactivate. This really doesn't make sense for a game that uses the XRRayInteractor already for distance grabbing and UI interactions. Am I missing something? Or is there a better way to do this?
Any help or code snippets would be appreciated.

There should be a climbing system implemented into the XR Toolkit. It could work like this - a grab interactable grabs a GameObject with a collider and climbing script. You then pull the controller down, which boosts you up. This could work for ladders, climbing walls, rock climbing, and more!

How to change Avatar's hand material programmatically? Is this possible right now?

If you place a prefab with some of the InteractableScripts on it (Select, Translation, Scale,..) and you delete these Objects, e.g when you want to reset the AR scene, you are not able to place more objects because the InteractionManager seems to be still subscribed on the Object.

When you use the raycast (XR Ray Interactor) the ray is always coming from the controller position and going Vector3.forward in local space of the controller. I don't see any option to customize this, maybe I'm missing it?

It would be nice to be able to set the starting point to be e.g. ControllerPosition + Vector3.forward * 0.05f and also to rotate the ray in any desired direction.

Depending on your game type you may want to adjust these settings. Even inside a single game (like Beat Saber) you can customize these settings to accommodate personal user preferences.

Maybe with the option to override relevant methods it could at least be scripted by developers per individual requirements.

Hi

I just wrote down code that highlights objects that are interacted with Ray and Direct Interactors.
Problem is that onEnter is risen for multiple objects at once in DirectInteractor, which is kind of strange.
Is there any more complex logic that i can't understand?

I changed the code in method
public override void GetValidTargets(List<XRBaseInteractable> validTargets)
so it will rise events only for one object at once and it is working fine

float minDistance = float.MaxValue;
XRBaseInteractable minBaseInteractable = null; 
            
// Calculate distance squared to interactor's attach transform and add to validTargets (which is sorted before returning)
foreach (var interactable in m_ValidTargets)
{
    m_InteractableDistanceSqrMap[interactable] = interactable.GetDistanceSqrToInteractor(this);
    if (m_InteractableDistanceSqrMap[interactable] < minDistance)
    {
        minDistance = m_InteractableDistanceSqrMap[interactable];
        minBaseInteractable = interactable;
    }
}
validTargets.Add(minBaseInteractable);

My question is are You interested in remarks like those and is it a good place to post those, since I'm making a lot of changes to your code and can contribute with few more.

If no it's understandable and I won't bother you any more:)

I am trying XR interaction toolkit with Oculus Quest. No matter what setting I try I see a really jittery movement both for grab interactables and for game objects attached to the controllers. Example scenes behave the same way. Is this supposed to be like that?

Refer the link

I would really like to see this Locomotion feature made available, too.

(in TapGesture)

(in GestureTransformationUtility)

etc, didn't search further (found these without searching)

How do I get if an object is currently being grabbed with an XR Grab Interactable, I need to turn the collider off when it's grabbed to fix a bug where you can grab an item and push yourself with it

1. Scan a table and a floor
2. place a cube on table
3. tap to select the cube
4. drag the cube to floor

The cube's positionY is same as table, can't place to the floor plane.

Hi people,
I wanted to give the Action-based XR Rig a try in my project. In Play mode I only have a frozen picture.
Then I downloaded this project and have the same problem in the WorlInteractionDemo scene. DeprecatedWorldInteractionDemo on the other hand works fine with the WMR.

I even tried adding bindings especially for the WMR in the Main Camera of the XR Rig and in the Input Actions window.
This was also unsuccessful.

Do you have an idea how I can fix this problem?

I have this issue reproduced using photon, but I guess there are other possibilities that I am not aware of. (EDIT: it is most likely when we disable the parent object of interaction before destroying it)
DoProcess in XRUIInputModule fails to remove RegisteredInteractables properly in case of using PhotonNetwork.Destroy and PhotonNetwork.Instantiate in sequence.

I have a scene which joins photon and spawns a player with xr rig and 2 rayinteractors. I press on UI item which does Photon.Destroy on current player and Photon.Instantiate another prefab with xr rig and 1 rayinteractor + 1 direct interactor.

When it runs through DoProcess() in XRUIInputModule.cs it executes else, even though registeredInteractable.interactable is null. It should instead remove the interactable from list.

Because of that I keep getting this error for the interactable that is not removed properly.

MissingReferenceException: The object of type 'Transform' has been destroyed but you are still trying to access it. Your script should either check if it is null or you should not destroy the object.

Hi,

Maybe I am missing something but I dont see any way in what we can get ButtonDown or ButtonUp value from InputDevice?

I installed the Oculus XR plugin, XRInteraction toolkit and XR Managemeent plugins. After installing them I am getting this error -
Library\PackageCache\[email protected]\Runtime\Interaction\Controllers\XRController.cs(283,35): error CS1061: 'BasePoseProvider' does not contain a definition for 'TryGetPoseFromProvider' and no accessible extension method 'TryGetPoseFromProvider' accepting a first argument of type 'BasePoseProvider' could be found (are you missing a using directive or an assembly reference?)
How do I resolve this error?

I have imported everything I need to get the project started but I'm still getting these errors from the "ControllerManager" class. Is there a package I'm missing?

Opened with 2019.3.0f3

My specific issue is that I am trying to setup a radial menu, but am unable to get the 2DVector info from the input because either I do not fully understand how to setup and use the input action system or my coding is bad (which could be likely as well). Would it be possible to create a prefab with a Serialized Public 2D Vector reporting said data (just visually in the script vs debug.log(xxx) so that it is easier to reverse engineer this for my purposes?

Additionally, I think it would be advantageous to create a script based system to activate if a system is detected (example - HTC Vive is detected - enable HTC VIVE Left and Right controller Scripts) or (Oculus Rift Detected - enable Rift Left and Right Controllers). Also i saw the InputAction chart and struggled there. Maybe a tutorial on setting up each button? I've yet to find a resource that covers it in the detail that I've needed to proceed. My apologies if this is not the right place for this comment, but I feel if yall are developing the code for this, maybe it will help other people too.

Example:

• creating a training solution for vehicles, or heavy equipment and requiring fine control via thumb sticks as grabable object tracking is not reliable enough for fine motor movement.

I am unable to find documentation supporting axis to multiple thumbsticks, and unable to find the support for thumbsticks in the packages itself.

I'm developing a AR application (using ARGestureInteractor in scene) and I'm using the XR Toolkit in version 1.0.0-pre.1 with Unity 2019.4 LTS.

In my use case I need to select an object via a UI Button click and not by directly tapping the object, for this I'm using XRInteractionManager.ForceSelect.
But when using XRInteractionManager.ForceSelect I can see that the ARSelectionInteractable selected flag is set true and also the event ARSelectionInteractable.onSelectEntered is invoked, but the selectionVisualization does not get activated and furthermore the gestures for moving, scaling and rotation also do not work.

Doing a physical finger tap on the object works, but that is not what I need in my scenario.

SteamVR is not on the list of XR Plugins, is it coming soon?

In the World Interaction Demo scene the UI line renderer is not working and teleport leaves the user several meters in the air

In the World Interaction scene the Vive controller does not register

It would be great to add an example of interaction where the object is not rotated to the attached position in order to be used in training simulators that demand hands-objects specific movements. All examples in this awesome project are gun-like grab interactions.
I would appreciate it if some can guide me to the code of the mentioned interaction. Thanks a lot.

XRCameraRig is supposed to replace OVRCameraRig but OVRCameraRig is the only place where you can set hand tracking support ("Hands only" or "Controllers and hands"). That option is not available on XRRig so even including hands the app is recognized by Oculus Quest as a "controllers only" app.

• How can I use hands in a UnityXR app?
• If it's not possible, will it be possible in the future?

Is the ARinteraction scene supposed to work in the editor?
I am clicking around and nothing happens.

Definetely using 2019.3, could be because AR_FOUNDATION_PRESENT is false for some reason? I do have ARFoundation 3.1

How can I force the XRDirectInteractor to release its held interactable?

Could we get this offered via Package Manager, so its easier to import into an existing project? perhaps as links (one for VR and one for AR) in the XR Interaction Toolkit package (like Polybrush does, for example)

This happens while in AR mode and a Plane is already detected. If the Screen is overlayed with a GUI, the CUI doesn't block the raycast and so on Button-Press an Object is placed.

Unity-Version: 2019.3.0f3 with XR Interaction Toolkit

The ray interactor seems to be going through all the geometry I have with (mesh) colliders in the Default layer. Override Line Length is unchecked in XR Interactor Line Visual.

I expect the end of the line to collide with non-Ignore Raycast layers, especially Default and not pass through it. The gradient would also adjust accordingly, giving the user a visual indication the line has shortened in case they can't see whether or not the line is passing through.

Unity 2019.3.0f5, XRIT 0.9.2

When using the XRUIInputModule and InputSystemUIInputModule, the mouse interactions on desktop PC are not working. When I disable the XRUIInputModule, it works again.
Please update the XRUIInputModule to work with the new input system.

Thanks!

When putting events into the Interactable Events categories on the XR Grab Interactable, the Interactable Events dropdown closes up whenever something is changed, meaning it takes many scrolls and clicks to completely fill the variables you need.
Unity version 2019.3.13f1 Personal

I created a couple of object that have a script which extends XBaseInteractable, they are correctly detected from the XRayInteractor but after a while the line and haptic feedback are update only for one of those objects.

Am I missing something extending the interface or it is a bug?

[EDIT]
The problem is that if you disable the laser while you are holding an object somehow the laser remember that it was holding that object and the only way to get it work with other ones is to let the laser enabled and release the object.

I built the VR project for Oculus Quest, and built it and ran it on the device. The scene geometry appeared too small, and there were some issues with the the raycast Line Renderers showing all the time, rather than just when a button was pressed.

This was on a Mac, running Unity 2019.3.0f3.

This could certainly have been something I was doing (or had configured) wrong, although I have built other projects for the Quest successfully. Note that I have also ran the project on a Windows box from the editor without issue.

At the core of the current design seems to be the assumption that objects need to be "selected first, then manipulated".

That's not necessarily desired behaviour, and there doesn't seem to be a way to configure this. Not even "dragging an object around" works without first selecting it.

To reproduce: build & run ARInteraction scene, create two cubes by tapping, try moving them around.
Expected: can move cubes around by directly dragging on them
Actual: can only move cubes around after first selecting them by single-tap. Directly dragging on a different cube than the selected one does nothing.

Using AR Placement Interactable, is there a means to add just one single AR Interactable prefab in the scene and not keeping adding more?

Primary use case for this is for apps where the user puts down one object in AR and wants to move/rotate it easily without additional clicks causing additions of extra prefabs into the scene through touch events registered by AR Placement Interactable.

Problem:
When destroying an interactable object while the interactor is still inside the object, a MissingReferenceException is thrown:

Reproduction:
Attach a XRGrabInteractable component and the following script to a GameObject:

After releasing the grab (selectExit), the object is destroyed but the exception is thrown.

Quickfix:
In order to quickly fix this problem, one could change the following in XRBaseInteractable.cs:
