Official XR Interaction Toolkit 1.0.0-pre.3 pre-release is available

Is there a workaround for this issue? I think it's messing with my pistol holsters

 

Is it just me or does it appear that the world space canvas now renders on top of the scene? Besides my own project I've also tried the XR Toolkit samples and here the world space canvas is also rendered on top of everything else. That's not what I've been expecting. I would expect a world space canvas to be hidden by objects in front of it. If this is expected behaviour (on Unity's side) how would I fix it? Using Unity 2020.1.7f1 and XR Toolkit 1.0.0-pre3

 

I'm having a problem with the Device Simulator. No matter what I do, I can translate and rotate the hands but I can only translate the head. Head rotation is broken for me. I tried changing key binds. I tried using stationary instead of room-scale. Neither worked. I can even translate both hands and the head at the same time. But when I hold "Rotate Mode Override" or press "Toggle Mouse Transform Mode" only the hands rotate while the head simply stops.

I'm using Unity 2020.3.0f1 and XR Toolkit 1.0.0-pre3 with the new input system in a brand new scene.

I added the following code below the line at

XRDeviceSimulator.cs:1429

to try and debug

Debug.Log( "anglesDelta: " + anglesDelta + "\tm_CenterEyeEuler: " + m_CenterEyeEuler + "\tm_HMDState.centerEyeRotation: " + m_HMDState.centerEyeRotation );

This was the result:



I also tried to change the sensibility of Mouse Rotate Sensitivity but that didn't work either. It just made the hands rotate faster.

Any idea on how should I fix this?

 

I don't have any HMD connected. I had both OpenXR and OpenVR Loader plug-ins activated but keeping only OpenXR on didn't solve the issue, sadly. However, inspired by your answer I tried a lot of combinations of settings in the XR Plug-in Management and made it work.

Turns out that having either the Mock Runtime in XR Plug-in Management > Open XR > Features or Mock HMD Loader in XR Plug-in Management on breaks the head rotation of the simulated HMD. I had to have both deactivated for it to work. Which is a bummer as this makes the HMD camera render as a normal camera, not as a HMD one (I need to see the occlusion mesh).

 

Just wanted to say thanks for continuing the development of the toolkit, it's been really helpful.

I have 2 suggestions -

- If you create an Action based Rig, I think the Input Action Manager script should be automatically added to the scene in the same way the XR Interaction Manager script is. At the moment there's no obvious reason why you're controllers don't move unless you add this script.

- It would be good if the toolkit could automatically setup or prompt you to change the project fixed timestep to match the refresh rate of your headset. When I first used the toolkit I thought the jitter when moving physics objects was something to do with the toolkit itself.

 

I am using the Built-in render pipeline and it was showing in the editor I don't think I had gotten round to checking it on a device yet. Now several days, a windows update and many restarts later the problem seems to have disappeared from my own project apart from one issue remaining. TextMeshPro - Text (UI) assets are still rendered on top of everything else (both in editor and in device). That's to say ... the .sdf TMP_Font assets that I copied from a previous project (and different Unity version) are exhibiting this problem. The default .sdf that comes with the TextMeshPro installation behaves correctly. I will delete the copied versions and recreate them. I will also check the VR Example project for any changes. But that's for later I gotta run now.

 

This is getting more interesting by the minute This morning I started up the project and the problem was back in the editor. I was about to try upgrading the project as you suggested when I remembered your question about if the problem also occurred on the device. So I tried it on the device and lo and behold it was working on the device with the exception of the tetxmeshpro issue mentioned above. Also after exiting play mode the editor was behaving correctly as well with afore mentioned exception.
Next I changed all the font assets to the default font asset that is part of the textmeshpro package. That worked correctly in the editor and on the device. I deleted the copied font assets and a textmeshpro material that somehow made it into my fonts folder and recreated the font assets. After assigning them both the editor and the device behaved in the manner expected.
Next I quit Unity and started it back up. The problem was back in the editor but disappeared after entering and exiting play mode for the first time with the device connected. I guess I can live with that,

 

@chris-massie is there a method to reset the camera forward to fit the rig forward? and reset the camera center to the Rig center?

 

@chris-massie

This might not be a bug perse, but I saw that multiple people encountered it. When I use the AR side of the interaction toolkit, I want to extend and make custom variants for translating,scaling,rotating etc. However some nessesary code is locked as private/internal or through other ways. In particular 'GestureTouchesUtility.cs' is private and I want to access it. Also the gesture.Cancel() function in ARScaleInteractable.cs is not accessible. It would be amazing if you would make all or most methods public available for us to use in custom implementation. Thanks in advance!

 

Does the XR Socket Interactor somehow stores the (direct) Interactor that but the interactible in it? I'm getting a weird behaviour where a gun keeps poping back into my hand when it's holstered in a socket and I press Select on my controller. I've put the socket a mile a away to make sure there is no collider interfering. If so, I can I somehow disable that?!

Edit: Seems like it is because I'mparenting the Object....


Edit2: Okay, after a few more testing I came to the conclusion that something has changed from 2020.3.0 to 2020.3.1 (and 2 too).
Here is the situation: I'm trying to make a gun holster which is a XR Socket Attached to the player. On Socket Enter, I parent the gun to the holster so it doesn't lag behind when I move the character (teleport is no option!). This was never a problem until I updated to 2020.3.1, because now, when I put the gun in my XR Socket and make it a parent of the socket, I can always select. The gun will always pop in my hand. It even does that, when the Socket isn't even connected to the player. You can walk always from it and the gun with be in your hand once hit select.

This is extremely inkonvenient. Reverting to 2020.3.0 now

It's probably kind of hard to understand what the issue here is. I'm having trouble myself to put this in accurate words. But maybe someone will investigate this or make an option to the Grab Interactiable that it would parent to the interactor in way that works better than my spaghetti code.

 

Thank you for your attention and suggestion. I just finished submitting the bug. In case someone wants to follow the report: https://fogbugz.unity3d.com/default.asp?1325407_eeatp68lrmr50urv

 

umm, it's like holding down the oculus button for a while then it will reset the view, is this possible?
Maybe method like InputTracking.Recenter? because it's obsolete

 

Hi everyone!
Does XR Interaction Toolkit work with webvr?

 

Hey @chris-massie

I'm currently encountering an issue when using XRGrabInteractables. I currently have a very large collider on my grab interactable and I noticed that when I let go of the xr grab interactable (let's say on a table) and my interactor is still within the collider and I attempt to grab again it will not grab the interactable.

It works half the time and only really works when I make it so my interactor leaves the collider boundaries and re enters it.

Is this by design? If so, is there a way to avoid this? When I let go of the grab interactable I want to be able to grab it again even if my interactor has not left the bounds of the collider.

 

Hi everyone!
Does XR Interaction Toolkit- action based work with htc vive cosmos?

 

Hey @chris-massie

I remember you posting this potential work around https://forum.unity.com/threads/xr-...re-release-is-available.1046092/#post-6866873

I tried doing this, but was unable to implement anything that worked. Do you have a code example?

 

Is there any work around for this? We have a box with 2 items inside, the user places the objects in sockets in the box then the user can teleport with said box to carry the items around, however sometimes when they teleport the objects will be offset from the positions they should be at.

 

I tried this and it seems to work when I test it in editor, but not when I deploy it on Quest.

Code (CSharp):

1.   public void RecenterPlayer()
2.     {
3.         subSystem = XRGeneralSettings.Instance.Manager.activeLoader.GetLoadedSubsystem<XRInputSubsystem>();
4.         subSystem.TryRecenter();
5.     }

Am I doing something wrong or does the Quest need something specific to recenter the player?

 

I found an bug in the XRGrabInteractable SetupRigidbodyGrab method.

The line rigidbody.isKinematic = m_CurrentMoveType == MovementType.Kinematic ignores the MovementType Instantaneous.

I have a grab object which has IsKinematic true in the editor and MovementType Instantaneous this grab method will falsely set IsKinematic to false which causes issues, see this post for more details why it causes issues, but short version, the rigidbody and controller will try to move the object at the same time: https://forum.unity.com/threads/xr-controller-object-spawn-jitter.1106497/

Visually the controller always seems to "win" because it sets the transform in Update and BeforeRender (with the default settings), but the transform values can be messed up if you use them during the Update method, in my case it caused random spawn object offsets and ray cast misses that use the grab object transform.

As a workaround I added a GrabKinematicPatch script to the same object which handles the XRGrabInteractable Selected event and sets isKinematic to true again

 

Hello @chris-massie,

I am not sure if this is the issue or intended behavior. I am facing the issue related to activate or trigger button especially for XRBaseInteractable class or whichever the class derived from XRBaseInteractable class.

I have created simple cube and have added the script to gameobject's component as "TestBaseInteractable" which is deriving the XRBaseInteractable class.

This class has the following script.

Code (CSharp):

1. public class TestBaseInteractable : XRBaseInteractable
2.     {
3.         protected override void OnActivated(ActivateEventArgs args)
4.         {
5.             Debug.Log($"activated");
6.         }
7.  
8.         protected override void OnDeactivated(DeactivateEventArgs args)
9.         {
10.             Debug.Log($"deactivated");
11.         }
12.  
13.         protected override void OnSelectEntered(SelectEnterEventArgs args)
14.         {
15.             Debug.Log($"select entered");
16.         }
17.  
18.         protected override void OnSelectExited(SelectExitEventArgs args)
19.         {
20.             Debug.Log($"select exited");
21.         }
22.  
23.         protected override void OnSelectEntering(SelectEnterEventArgs args)
24.         {
25.             Debug.Log($"select entering");
26.         }
27.  
28.         protected override void OnSelectExiting(SelectExitEventArgs args)
29.         {
30.             Debug.Log($"select exiting");
31.         }
32.  
33.         private void OnTriggerEnter(Collider other)
34.         {
35.             Debug.Log($"trigger enter");
36.         }
37.  
38.         private void OnCollisionEnter(Collision collision)
39.         {
40.             Debug.Log($"collision enter");
41.         }
42. }

I had performed the following steps below.
1. My controller is touching the cube, and pressed trigger button, OnActivated and OnDeactivated method, supposed to call, but I do not see any output below for activated or trigger button.

2. If I press grip button then I see below output

3. If I press grip button first then press trigger button then OnActivated and OnDeactived method gets called. It works only if I hold the grip button and then press trigger button and I see output below.


My Question is how to get called OnActivated and OnDeactivated methods, just by pressing Trigger button alone. Is it intended behavior or is it an issue. Is there a way workaround fix in order to get the OnActivated and OnDeactivated methods called? What scripts I need to change and get those methods working?

Thanks,
Avinash

 

Hi, I'm having an issue that I haven't run into before. Because earlier it worked. I'm using the xr packages and openXR. When I run a scene where I'm the host/server and I play the game. Everything works as expected. The events from the XR interaction toolkit are working as intended. Once I become a client and another person is server, I can't press any buttons. I tried debugging it and it just doesn't see any input coming through. So as long as I'm not connected to a server everything is okay? I think this guy ran into the same problem but he has no fix for it https://forum.unity.com/threads/unity-xr-problem-at-runtime.913136/ . I believe it is a Unity bug since it used to work. (around 2 months ago were my final tests) Using the new Unity input system everything seems to work fine but now I have to do my whole input system again instead of the xr interaction toolkit

 

Can you add a click option for the Snap Turn Provider? Currently, there's only a single action for each hand that can be bound to a turn. So if I set it to track pad, just gently touching the track pad causes a turn. But the typical way this is done is on clicking the track pad. I just made a local change to add 2 more fields that allow me to bind a trackpadPressed action, and check if that is down, if applicable, before returning the left/right hand action results.

Continuous move should really have the same option as well.

I can post my local changes if that's helpful.

 

@chris-massie Thanks for the reply. I got it working by adding new additional methods OnActivateEntered, OnActivateExited, OnActivateEntering, and OnActivateExiting, and followed the same code flow as in OnSelectEntering and other select methods. The reason is so that I wont be able to disturb the Activate and Deactivate methods.

I appreciate your help.

I am having an issue with below requirement.

I have been using XRGrabInteractable on a simple gun mag. On other hand I have a gun attached to my hand and added XRSocketInteractor in child of the new game object with box collider using trigger.

When I hover the mag close socket interactor trigger, I want the mag to force select/move to the target without releasing the grip/grab button. How do I achieve force select/move when hovering the socket with the mag in hand and also is there any work around for this. Do I need to add/modify methods either XRGrabInteractable or XRSocketInteractor classes? Appreciate your help on this.

Thanks,
Avinash

 

Hi there @chris-massie!

I have a question if you don't mind asking:
In a scene where multiple Interactors are next to each other. (e.g. multiple socketinteractors inside a chest)
How does the toolkit prioritize which interactor will interact with the interactable?
I want only one interactor (e.g. the one closest to the interactable) at the same time to trigger his e.g. onhover event, etc.

How would one do this?

As far as I read the documentation there is only one list for the other way around m_ValidTargets, which defines the list of interactables that an interactor can interact with.
What I need however is a list of all the interactors, that an interactable can interact with.

Are you able to give me some documentation that I could read into?
Your help would be much appreciated!

Dummy code:
Hook yourself to the on-hover event of the pistolslot.
then
selectexited (hand, gunmag)
InteractionManager.ForceSelect(gunmag, pistolslot );

Feel free to read the docu regarding stuff like this.
https://docs.unity3d.com/Packages/c...on.toolkit@1.0/manual/index.html#architecture

There is also a realistic gun guide from valem, that could be helpful for beginners like you:
https://docs.unity3d.com/Packages/c...on.toolkit@1.0/manual/index.html#architecture

 

@Khang_Pham Thanks for the solution. I have removed the old code and used yours, I didn't know there was ForceSelect method. Thanks for the help.

 

no problem.
Glad I could help

 

Thank you very much for the explanation! I have dug into the code and came to the same conclusion.
The above explanation you just wrote is very a good rundown and it might make sense to add it to the official documentation as well (if not already there).

Overriding the CanSelect and CanHover methods is definitely the easiest way to do it. I will have to dig into detail on how the XR interaction toolkit manages the list of interactable first tho. As I plan to mimic this logic for the validinteractors list. I think using the same logic that you do for the interactable list, makes sense as a self-written solution by me can easily become bad for the performance. (checking the distance of all interactions all the time etc.)

I appreciate the explanation and I am very much looking forward to the next release and the next doc wiki version!

 

Hello, if I am using the XR interaction debugger I see there is a value called indexTouch that turns true when I am touching the trigger button. I cant seem to find indexTouch when I am trying to bind an action to my action map. Please advise

 

Looks like version 1.0.0-pre.4 is out already, should this thread be updated?
Btw I had version pre.3 and for some reason the Unity package manager didn't show that there is a newer version (usually there is a changed icon and update button) I had to manually update to version .4

 

When I am binding the action my Action Type is set to "Value", my Control Type is set to "Axis", and the binding I am using is "trigger touched [Left Hand Oculus Touch controller]". I am not getting the touch response when debugging, am I doing something wrong?

 

I am calling ForceSelect on the manager, but my object does not get selected. I did a test and added the object to the interactor's starting interactable and on start up it gets selected. I remove it from the starting interactable and then call FoceSelect myself with the same paramenters (after the game started). Does not attach. Any ideas ?
