This is just what I was waiting for! A simple way to make things like backpacks and stuff with sockets. Thank you so much for helping out the VR community!

[@JustinPBarnett]

You're so welcome!

[@FusedVR]

Super comprehensive. Very nicely done!

[@JustinPBarnett]

Thanks!!

[@tientam779]

Once agin, great and simple to understand tutorial. I like that you're always checking up on XR toolkit from Unity and making new tutorials about it, allows anyone new to just jump right in and get started with those tool!

[@JustinPBarnett]

Glad to help!

[@Ollie_sm]

could you do a tutorial on how to make it possible to climb and glide and even an accurate gliding mode where you can steer up and down using your hands

[@JustinPBarnett]

Ooo that’s a cool idea! I’ll add that to my list!

[@Ollie_sm]

@@JustinPBarnett thank you so much!

[@Ollie_sm]

@@JustinPBarnett mechanics similar to this would be great kzbin.info/www/bejne/oHbMfJVoYqmXerM much better than gliding in most vr games

[@infectedgoat99]

How did you figure all this out on your own? Incredible video, super helpful. ALSO for anyone struggling with getting the hammer to face the right direction when holding, make sure in the XR Grab Interactable script that you drag your empty game object "Attach Point" onto the "Attach Transform" otherwise the object wont use your attach points!

[@JustinPBarnett]

Lots of testing and just playing around in Unity 😜 and thanks for the tip!

[@V-ROCstudios]

Thanks. I kept thinking I needed to rotate a component.

[@k1ng401]

haha just worked this out myself and then thought "someone else must have had this problem..."

The timing on this video couldn't have been better. Ran into the missing XR Interaction Toolkit issue yesterday when I updated to 2021.2.6f1 and today I decided to check out my go-to Unity VR resource on KZbin...and what do you know? :)) Massive thanks for all the content, would take me forever to figure this stuff out on my own.

Heads up, Toolkit is spelled wrong in your title. It says tookit. Great tutorial keep em up!!

[@JustinPBarnett]

Holy cow, totally missed that! Thanks!

[@bones99999]

Very nice tutorial. Thanks. My new favorite channel. Could you do a tutorial on Hand interaction with colliders on say a desk or wall? Specifically, where if you push the controller through the desk, that the hand stays on the desk until you bring the controller back to the hand position and it will track with the controller again. Or is this built-in to the tool kit? I know some VR interaction tool kits have this feature.

[@JustinPBarnett]

It's not built into the toolkit, but I have made a video about physics hands! Check it out: kzbin.info/www/bejne/iKiqeqyIrpJ_qdU

Hi Justin, great tutorial! would you be able to show how to do power cables with the Obi Rope addon like plug in and un plug :)

[@JustinPBarnett]

That’d be cool! I haven’t used it but I’ll look into it

[@Calactic]

Thanks for this, helped a tonne. I'm just wondering, how would you go about making items being able to stack up on each other? Our game is a survival/horror game and we want players able to put more than one of the same item into a hotbar, which is a sphere socket interactor. Our game takes heavy inspiration from "A Township Tale" if you're familiar.

[@firizz]

have you found the answer? plese let me know if you do

[@BlackDev]

I love your vids self taught inspiring game dev have been binge watching your vid and using them as projects but i cant figure out where im going wroong here my line visiuals arent tracking they just go up and down

[@cryptopedia7257]

hey justin really love the conent. can you make a video on unity vs unreal engine 5 for vr development !!!!!

[@JustinPBarnett]

Yea! I actually dabbled around in unreal for a bit before coming over to unity. I talked about it a bit in my “What you need to start VR” video

[@Riprog]

Hey Justin! Love your content, keep it up! I have an issue with using XR Socket Interactors in multiplayer applications using Photon (PUN 2), so far I've gotten no response on the Unity forums. The problem I face is that if a player puts an object in a socket and then grabs it again, the item remains in the socket for other players (not seeing that a player has a grabable in hand). The item has a photon view component on it and also a photon rigidbody view component, I suppose you need to add some component to the socket interactor? Thanks in advance!

[@user-yn1sy9bt4w]

I have the same problem, just yesterday I saw your post on the Unity forum :). Justin, if you can give any advice would be very grateful too!

[@JustinPBarnett]

So my initial guess is that is has something to do with parenting the object. Maybe try adding a script to have it follow the socket attach point every frame instead of parenting it. Just a guess though.

[@petitwhito3196]

Hi ! I have the same issue, have you found the solution to the problem ?

[@Jason-eo7xo]

so awesome!

[@JustinPBarnett]

Thanks!

[@torstenknodt6866]

Great video, thanks! Is there a way to check dynamically whether a socket interactable could really be dropped on a socket interactor or there is some use-case specific condition which does not allow it?

[@kathy02158]

who can tell me if i want use xr sockets apply in slot and become 2d image ,how should i do?

[@gnomge]

ayo hold on, letss goo, exactly what i needed. btw i need to add a simple bean to act as the character, like follow the xr rig, cuz when i put it under the xr rig it doesnt follow the camera movement, but when i move it under the camera, it breakdances on me. oh and also how the hell do i stop my character from being able to fly when holding an interactable ways to recreate: create basic xr rig (action based) create an interactable, hold the interactable under the player.

[@JustinPBarnett]

You can checkout my VR movement video for getting the collider to follow your camera. And in order to prevent held things from interacting you should set them to an “interactable” layer and set the player to a “player” layer and then in your project settings > physics make sure in the grid that the checkbox between the layers is unchecked so they don’t interact

[@gnomge]

@@JustinPBarnett thanks a lot! also does ur video include adding a visual character to the xr rig? cuz my project is a vr shooter and it needs the character to not only to have a body, but the body to have a collider. so how the hell do i set up the character model (i only need it to be a bean) to the xr rig?

[@JustinPBarnett]

@@gnomge I do have another video about that! Inverse kinematics

[@dracula9202]

Impressive! Thanks for sharing! I wonder if there is a workaround so that only objects that are being grabbed atm can be selected in the socket. I already tried to play around with some things in the public override bool CanSelect(XRBaseInteractable interactable) interactable.isSelected.. but nothing seems to work xD Thanks in advance if anyone has a hint^^

[@JustinPBarnett]

I was actually playing around with that today and couldn’t find a solution for that either 🤔

[@Acilianus]

I know it has been 4 weeks now, but It was tricky and I found a (mostly satisfactory) solution so posting it here for you in case it is still relevant. What I did is I switched the layermask on the interactable when the interactable hovers over the socket (OnHoverEnter interaction event) to a layer which can not interact with the socket, on the condition that an XRDirectInteractor is not currently selecting the interactable. The tricky part here is that you have to switch back to the originla layermask. First my intuition was to do it on the OnHoverExit event, but since the interactable was moved to another interaction layer, the socket was not detecting events on it anymore... So instead I implemented a coroutine which resets the layer mask on the interactable if the interactable is selected, or moves away a certain distance from the socket. This mostly works well, the only hiccup is that when the (ungrabbed) interactable falls into the socket, it still stops for a second before falling through it. However, the socket will not pick up the interactable even if the interactor rests right on top of it. Here is the code for reference (the disableInteractor method is bound to the OnHoverEnter event of the socket. Note that interaction layer numbering starts from 1 not 0. Also note that when the interactable hovers above the socket it already counts as selected. ): // Disable the interactable if it is not grabbed when placed into the socket (e.g. it conincidentally falls/bumps in it) public void disableInteractor( HoverEnterEventArgs eventargs ) { XRGrabInteractable interactable = (XRGrabInteractable) eventargs.interactableObject; if ( interactable.interactorsSelecting[0].GetType() != typeof( XRDirectInteractor ) ) { //interactable.GetComponent( ).enabled = false; interactable.interactionLayers = 2; StartCoroutine( reEnableInteractor( interactable, interactable.interactorsSelecting[0] ) ); }; } // Reenable the interactor after an accidental fall/bump into the socket private IEnumerator reEnableInteractor( XRGrabInteractable interactable, IXRSelectInteractor interactor ) { while ( Vector3.Distance( interactable.gameObject.transform.position, interactor.transform.position ) < 0.2f ) { if ( interactable.isSelected && interactable.interactorsSelecting[0].GetType( ) == typeof( XRBaseInteractor ) ) { interactable.interactionLayers = 1; break; } else { yield return new WaitForSeconds( 0.1f ); } } interactable.interactionLayers = 1; } Hope this might help some people.

[@djmedina50]

Hello Justin, I like so much your videos. I have one question. I've followed your tutorial to try to do an inventory but at the moment I hide de canvas all the items that I have shocked falls down. What can I do to make the Items be hiden with the canvas and showed again. The inventory is a canvas with Slots that can be showed and hided pressing the button X of the left controler in Oculus quest 2. Thanks and best regards.

[@k1ng401]

Did you miss a step? Were you supposed to make the Attach Points selected in the Attach Transform selection? Until I did that, it was ignoring my Attach Points completely and the hammer was facing the wrong way, the shield was being held right in the centre

[@JustinPBarnett]

Yes I did that!

[@k1ng401]

How do we make the hammer and shield collide with each other when held? or is that not possible. I see they collide with the world and they collide with each other when not held but I can't bang them together while holding them. I don't know if I ever will want to but it might be handy to know

[@JustinPBarnett]

Change the grab interactable component grab type from instantanious to velocity tracking

[@alejandrodelgado74]

Awesome thanks so much….. unity should by default setup your scene….

[@JustinPBarnett]

Yea that'd be nice. There is a VR template, but it's not really that great

[@Ctorresification]

Great tutorial! Is there any way to make it so the player has to place the interactable object into the socket? I have a socket attached to my players finger for attaching rings and I can pick up the ring with one hand and put it onto the finger of the other hand just fine, but I can also just move my hand over a ring sitting on a table and it will snap to the socket automatically. I want the player to manually drop the ring onto the finger.

[@andreramiro732]

How can i do this with the Oculus Integration (OVR)?

[@k1ng401]

Only renders in the Left eye. Did I accidently click something I shouldn't have?

[@JustinPBarnett]

Try going to project settings > OpenXR > and swap render mode to multi-pass

[@k1ng401]

@@JustinPBarnett Yep! That fixed it. NOTE i have both the PC and Android OpenXR setting and first I tried it on the Android part and it made no difference so I did it on the PC setting part and it worked. So basically it's the PC Settings that matter when streaming from the PC to the headset and the Android if you Build and send the file to the headset to play it there? is that correct?

[@JustinPBarnett]

If you're building a game to release go with the latest 2020.x LTS version, but if you're just learning then I'd recommend using the latest non-beta version! Does that make sense?
