Introduction to VR in Unity - PART 7 : DOOR, LEVER, DRAWER,...

[@ValemVR]

Hey guys ! I made an update of this series on my channel Valem tutorial that you can find here : kzbin.info/www/bejne/nH6TnGWkbNprqcU

[@ValemVR]

Hi guys, hope you enjoyed this video. Here is a little bonus for you. Bellow you will find a script that you can attached to any gameobject with an HingeJoint and that will trigger a particular Event when it reached its min or max limit. You can use it to trigger anything you want with the lever for example !! :) ------- using UnityEngine; using UnityEngine.Events; public class HingeJointListener : MonoBehaviour { //angle threshold to trigger if we reached limit public float angleBetweenThreshold = 1f; //State of the hinge joint : either reached min or max or none if in between public HingeJointState hingeJointState = HingeJointState.None; //Event called on min reached public UnityEvent OnMinLimitReached; //Event called on max reached public UnityEvent OnMaxLimitReached; public enum HingeJointState { Min,Max,None} private HingeJoint hinge; // Start is called before the first frame update void Start() { hinge = GetComponent(); } private void FixedUpdate() { float angleWithMinLimit = Mathf.Abs(hinge.angle - hinge.limits.min); float angleWithMaxLimit = Mathf.Abs(hinge.angle - hinge.limits.max); //Reached Min if(angleWithMinLimit < angleBetweenThreshold) { if (hingeJointState != HingeJointState.Min) OnMinLimitReached.Invoke(); hingeJointState = HingeJointState.Min; } //Reached Max else if (angleWithMaxLimit < angleBetweenThreshold) { if (hingeJointState != HingeJointState.Max) OnMaxLimitReached.Invoke(); hingeJointState = HingeJointState.Max; } //No Limit reached else { hingeJointState = HingeJointState.None; } } }

[@kingfhd2424]

Now thats Epic. Can you make climbing (or you cant do that)

[@Okerishma]

This solves exactly what I was struggling with. THANKS!!

[@kingfhd2424]

valem this is week can upload a video?

[@ayitsalex2893]

I want to get into vr development and I find these videos incredibly helpful, please never give up on us 🥺

[@jonasmg]

9:04 god I love that reference. Thank you for both teaching and having excess energy to joke around xD

[@LivanderGamedev]

continue this series please, I love it and I want to learn more

[@donmacsween2842]

Great video as always, but could I suggest a tutorial on creating custom hand poses for grabbing different shapes? As having the player's hands disappear every time you grab is very immersion breaking.

[@Wayloz]

In his earlier tutorial of this exact series of tutorials, he explained how to import custom models and animate them depending on inputs.

[@Xzarations]

I could tell you might have been watching Dani lately based on 9:07

[@meeperhere]

ye ur right

[@deathcoredude6565]

Valem, I currently work with UNMC in VR simulation and there has been so many times your videos have saved me. Thank you so much for all your hard work!

[@xanderbuyst1521]

these videos are amazing and so helpfull, keep em coming!

[@PhillipsAlbright]

Hinge joint is useful to know even outside of VR, great things to know from this tutorial

[@jaythevrgamer7140]

Thanks for being so detailed! For me, the user interface was really hard to get used to at first. But, like any software, it becomes pretty simple after a while and pretty user friendly. Good stuff!

[@mfproduct]

Your videos are fantastic, just stumbled across you there other day and loving the content. You don't waste time with long intros or fluff, just straight into the doing of things.

[@TreFlack101]

Jumping and Sprinting with this controller would make this new Subscriber VERY HAPPY!!

[@denisthefuzz]

Valem, tu résouds tous mes problèmes. Un grand merci. Je vais essayer d'implémenter tes solutions dans mon projet, et ensuite j'irai sur ton patreon. Incroyable, après m'être infusé des tutoriels incompréhensibles pendant des plombes, j'ai enfin trouvé tes vidéos et je n'ai plus qu'à suivre le guide... Je viens de regarder les 7 à la suite ! Encore merci, j'espère que je vais y arriver.

[@UXVirtual]

Thanks for making this video! I've been trying figure out how to optimally use the physics joints in Unity for VR. You really explain it well and your approach will be universal to other Unity VR interaction frameworks too.

[@GwynPerry]

This is excellent. I wasn't expecting it to be so straight forward. The only thing I would say is missing is having Unity detect the extents of the lever and make something happen. So if you pull it all the way down, have it play a sound and invoke an event that other game objects can listen to.

[@ValemVR]

Hi my man, check the pin comment I made I attached a script that does exactly this job! :D

[@GwynPerry]

@@ValemVR yep, that's great. I noticed it after I commented.

[@taxemicspark]

This video has helped loads with my current project, even though I'm using a more updated version.

[@simonthedigger99]

love the series man im working on my final year project and decided to build a VR racing game and this series is really helping specially this video keep up the good work

[@toddandlar7359]

I've been subscribed for awhile but have really been out of coding VR for awhile. Since playing half life VR I have been waiting for a proper implementation without any crazy hacks for doors and drawers and such. This is so much awesome I can't thumbs up enough. Thank you!

[@Ciroisnthere]

THANK YOU I'm not making a vr game but it still helped me ALOT in pc gamedev

[@sparkarg677]

Hi Valem, I don't know wheter you will read this or not, but i do really thank you for all of your videos. My final degree project was made with VR and didn't know almost anything, and all your tutorials have helped me a lot. As soon as I find a job, i can ensure you that you'll have another patreon subscriber ❤︎.

[@THOMASXDXDXDXD]

Excellent video, Valem! This series is definitely the best about Unity XR Toolkit I've seen on KZbin. Thank you!

[@Louuloutre]

I want to say thank you so much for all of your tutorials it helps me A LOT ! Mercii fois 1000

[@rikusoulz]

You are really doing a really good work, keep doing this, you help a lot of people!

[@Ctorresification]

Awesome tutorial Valem! Might I suggest a tutorial for climbing next? Or snap placing grabbables? Like a magazine into a gun, or a key into a lock?

[@adhochero6619]

hey @Valem thanks so much for the tuts. i was able to use the hinge joint on the lid of a pirates chest. i also added a rigid body to the bottom part of the chest and set it as the link rigid body for the joint, that way when i can pick up the chest to carry it around and also if i grab the front i can open it up with the joint. it works great.

[@JTHBS]

A whole tutorial without coding :O unbelievable :D

[@jaredmiller7257]

Can you please make a videos about guns.. like ammo, reloading, and ammo clips

[@max109y]

Nice tutorial these help a lot and im glad u teach them in Unity! 👌

[@4vrstudios]

You are the best! Thank you so much for helping us!

[@andrewdowns4777]

Love this series, man. Keep it up!

[@EazybakeTV]

Great Job! This will be very useful for me in the future.

[@boulderplayz6712]

Hey valem! I REALLY wanna make a grappling hook in my brain game. It would be amazing if u could do a vid cuz ur format is really easy to understand

[@DmitriyChaban-dmi3coder]

Spent 6 hours with chatgpt trying to make this lever, found your video - 5 mintutes - resolved. One tip for those who're stuck - don't put the rotation inside the floor, otherwise it'll bounce back

[@nicolasenriqueruedarincon469]

Lever tutorial starts at 6:15

[@yolokas]

What are the differences/benefits for using unity XR instead of Steam/OpenVR ?

[@_Garm_]

what an awesome tutorial! :D

[@adhochero6619]

aye, cool stuff man, thanks

[@LiquidCurtain]

Great series! I keep coming back to these videos every time I have a problem. Is there any easy way to force a controller to release a held object? I'd like to be able to disable or destroy an item after the player uses it, but I can't as they are still holding it.

[@PhantomWolf93]

How can I make the player stop grabbing the door if he is walking away? The door even breaks if I grab it and move too far. Thanks for your videos!

[@WaffleCat]

Heya, I have the exact same issue now. Have you maybe found a fix yet?

[@valentinsourice3780]

We are several with the same issue (mainly lever / door stabilty) we opened some thread on it (KZbin does not let me put the link...), you can find us by taping "xr plugin grab hinge joint" on Google.

[@ramkeshsingh4051]

Hi , Please make tutorial to make spaceship simulation .

[@M_Ryze]

My Grab Ray Ignore layer won't work. I disabled body to grab ignore, but the ray still shows up and interacts. Edit: Fixed! select both (left/Right) Ray Interactor(s), go to XR Ray Interactor and go to Raycast Mask, disable everything first, then enable UI, and Grab.

[@alexmartos9100]

Best tutorials ever!!

[@wtfimcrying]

hey valem! good video but can you possibly make a video about simulating weight in vr and giving your player weight similar to boneworks? just a suggestion.

[@lukenowlandfilms]

Thank you. THANK YOU.

[@jesco_xr]

Hey @Valem, do you remember how you made the tutorial about extending the OVR Grabbable to work with Hand Tracking and the normal OVR Grabber. Any chance of doeing an extension script to the Unity XR Toolkit? :)

[@FynnGB]

I would be really interested in the hand tracking integration as well! I heard that it is not compatible with the xr interactive toolkit yet and I'm curious to see a work around or a proper implementation if it exists yet

[@andriy_z]

Thanks!

[@Mex-ge9kj]

I really need to know how to make vr enemies and vr portals for quest, cuz I'm gonna use them for a test game I'm making.

[@TheRedMC]

I don't know if you're still looking for the help with this at all, but VR enemies and regular 3D Unity enemies wouldn't be that different. You could likely use some regular Unity tutorials or something.

[@Mex-ge9kj]

@@TheRedMC ok, thanks!

[@danielgalli6760]

thanks you so much valem for your tutorial, you are doing something that anyone is doing! i got a question, how you will deal with the drawer or the door to dont get clunky or jittering when you hit with a object like the gun or the ball? i dont want to change the layer, i like the "freedom" of close te door using the gun for example.

[@DenisGamer]

Hi Valem, I have been researching vr, and have come across resources to develop, i need some advice. Do you recommend using the OVR Oculus Integrations together with VRTK or is it better to use the XR resources from this tutorial series? Does it depend on my target platform?

[@fresoapa]

Actually, the InteractionLayerMask is a bit confusing and it doesn't help the documentation is wrong. Looking at the code, it doesn't care about the GameObjects layer, but just misuses the layers for its layer mask. It is better to think like this: * For interactables: Flag the object for what kind it is. - Gun should be pickable directly and remotely and slottable into inventory: Set Interaction Layer Mask to RemoteGrabbable, DirectGrabbable, Slottable. * For Interactors: Flag the layers that should work with this interactor. - RemoteGrabber? Set mask to RemoteGrabbable only. - Inventory socket? Set mask to Slottable only. With this thinking, you don't even need to change any layers in the game objects. Everything can be set to default. At least regarding XRIT interactions.

[@m1dn1ghtfury]

@Valem thanks for your tutorial series on how to setup a basic VR project in unity, I've found it extremely helpful and informative and as I'm new to XR development your videos are a godsent. I do have one doubt though, when I attach an XRGrabInteractable component to the door with the Collider as door handle, for some reason I can still grab the door from anywhere on its body. Do you know how to fix this

[@thebutterappletutorials6553]

Are you going to make a video on 2 handed weapons/objects?

[@Ziboo30]

Awesome video thanks ! I'm trying to do a turn table, or a valve and have difficulty. Any chance you could do a video on circular interactables ? also push buttons :) Thanks !

[@lucasmartinic2039]

Yes that would be awesome, have you had any luck with this Robin?

[@Ziboo30]

@@lucasmartinic2039 I rewrote the all XR interaction system ^^ keeping just the low level stuff.. wasn't suitable for my needs...

[@stevencraft7144]

The offset grabbable stuff doesn't work very well, from what I can see anyway. If you grab the drawer and then rotate your hand (without moving the position of it) the draw moves in and out, and when you release you'll see the drawer is in a completely different position to your hand? The door behaves somewhat similarly, but on top of that, simply moving the door, the movement isn't mapped 1:1 to your hand, so you move your hand a small amount, and the door moves a lot. If I switch back to using the default (non-offset) grabbable, all this is fixed, but you get the jump/snap when interacting.

[@MaxximaUnitysurabaya]

Hi, a question. Using hinge joint if I try to pull away farther than where the object is supposed to be, it will then move frantically like a possessed person. Does the script that you gave in the comments counters that, or is there another script needed to handle it?

[@Trivimania]

Maybe a strange question, but in the video you grab a drawer. Where could I plug in a piece of code to execute whenever the drawer is opened ? Is there some kind of event system for that or so I actually have to add a script to the drawer that constantly checks its position in world space ?(using a lot or cpu power)

[@richardosborn159]

wow, thanks!

[@zachdavis6624]

super helpful but can you make one using configurable joints and a joystick?

[@Tinotin12]

Make a tutorial on how to interact with an object in your hand by pressing A, B, X, or Y on the controller.

[@jaredmiller7257]

I 2nd this

[@JackTYM]

all you have to do is change the Trigger/whatever on the Hands to whatever button you want instead of trigger/grab

[@rocketjumper5419]

I am stuck on the drawer section, for some to me unknown reason I can push the drawer through the back wall of the cabinet. Is there anyway to fix this?

[@LuisGonzalez-ot5cg]

yo fr did you fix this??

[@danielgarciagonzalez2391]

Oh man, if only you could show how to create buttons that don't rely on gravity and yet the button animation works with VR hands, now that would be the OG.

[@KaineReiN]

Hi, Valem. Can you make a tutorial on how to customize object in-game? Like when I select a ball and a menu pops up on my hand and I can customize the ball's texture, color etc

[@jasonallen6330]

I got all your different joints to work. However I would like to see a tutorial on how to make twist nobs. I thought at first they would be like tiny levers. They seem to be a bit different to me than that. Any ideas?

When you are using the "grab offset" script. Dont use the AttachTransform value, things break because of that!

I try do this on my current project, but i don't have a good response of my movement when I try to open/close the door :( the feeling is not good, it feel like the door is heavy ... I notice that the movement is more accurate when I rotate my controller same time ... but not very smooth and ergonomic

[@FireChicken747]

It is behaving very strangely for me. I Had to put on both colliders set to trigger because it would glitch out but when i got it working. It would behave weird. when i grabbed it, it doesn't read with the forward or backward motion but rather me just spinning my hand. Does anyone have a fix for this?

[@wade065]

May I ask why the door will be pulled out when the controller is backward?

[@Individ1984]

Thank you a lot!!! But i dont get, why my box dont stop when i closing drawer :( I think its linear limits in + and - at same time.. if i set 0.4 to linear limit that means +0.4 and -0.4..

[@nathantripodi]

I dont know if it is in another video or if I'm just missing something but my hand does not seem to disappear when I open the door and infact you can see it no where near the door handle (When the player moves) ASWELL as being able to move far away while "still holding it" and then the door spazzing out.

[@nathantripodi]

Also, what video is it where you create the body layer to stop the objects from pushing the player?

[@MuscleDoraemon]

Your video is helpful. However, I met a problem when trying the lever. The lever always will come back to zero. It will not stay on max and min limit. Even though I adjusted some values, it only reached max limit, and it still does not reach min limit. What should I do?
