Was struggling with how to get the value of the input from an XR controller with the new input system compared to the old "InputDevices.GetDevicesWithCharacteristics......." way. This helped me out a bunch, thank you!

[@JustinPBarnett]

You're so welcome!

[@gizmobly350]

Thanks! This was so helpful! I started some Unity VR dev stuff awhile ago and got the basics up and running with the old system. I was so excited making cool 3d models to interact with that I fell down a Blender rabbit hole for the last year. Just started VR back up this year and was like, "Oh, what the heck! Action Input!" Even after watching multiple tutorials on the new input system, I still felt like an idiot. Just had a hard time grasping it. Seems like everyone explains it in a little different process. I was just going to stick with the old Device way. Not anymore! I feel so much better with it now. The way you explained it made it click. Great job! Can't wait to see what you put out next! For ideas for other tutorials. I really love the game Raft for it chill out and build up vibe. I would love to do a VR Raft type game in space where you just float in a little craft and cast out a tether to catch space debris. Crafting up stuff to grow your little ship and eventually save the universe. I've been trying to come up with a way to shoot out a tether(fishing line) and snag objects that float by and reel them back in. How would you implement a grappling hook/tether/fishing line thing? I could just use the ray interactor? But I would want the tether to have physics so it starts out loose, gets taut once it snags something, and sort of lobs it back to you. I know I'm punching above my weight class. Probably need to make a bowling alley first. :) Thanks again!

[@Mad_Luv85]

bro the way you just setup the keyboard and all that was amazing havnt found a video on it. is there any way you can do a video on creating a crosshair spread on player movement such as walking in VR. id love help on this... not sure the best efficient way to do this as ive been told use GUI but ive been told use iTween. not sure.

[@JustinPBarnett]

There's definitely a UI tutorial coming out in the next few weeks! Not sure you would need the crosshair spread (worse aim while moving) like normal FPS games because the user has to aim themselves in VR, but you could absolutely apply that to the end of a gun raycast if that's what you need for your game. Tutorial to come!

[@Mad_Luv85]

*I'd love if you could show me the best way to make an animated crosshair that moves on input with walking around which I can essentially attach to my dome. This would help me tremendously. I know reticle placement and scale is different for VR. My crosshair always seems to flicker n shake and I'm not sure why lol and it's when I'm moving. It's like it's trying to play catch up with the frames. // So how I invision the UI and Mechanics and perhaps it's not practical but The reticle is attached to the cam so where you look is where it aims. If I'm wearing the headset and look up ..I'm aiming up to the sky with my crosshair only except from my view I'll only see the hud and crosshair. I will never see my actual character and never my body model nor weapon. . However when i Iook up if an online player is looking at me or shall I say my character , he will see my character looking up aiming the gun up to the sky. I have alot of research to do clearly. But for now I'm trying to get some basic hud designed and some basic functionality before I can tap into what's replicated and rendered per player vs what's not. Definitely going to test alot of different things. Iti give a better example here's more about it if you got the time. so in my brain which is complicated I have a vision. Id like to prototype a proof of concept like "The old ghost Recons or rb6 Rogue spear games but with hybrid controls - with that being said the idea I have is - it's like a hybrid control system ***(because I want something that players can be somewhat familiar with) but it's A mix between 'Familiar controls" with some VR functionality. Essentially I want to use the controller like normal to move around. With the right controller being able to snap at degrees and or smooth turning as well. And being able to look freely in VR is important as well. however I want it so when your in VR that only you can see your hud such as things like " character stance" on the hud , you can also see your weapons icons and your reticle/crosshair. There are certain things that you'll be able to do as a character in VR when it comes to mechanics that just won't be replicated over the network to other players Intentionally. This was done in games like battlefield 5 when your teammate is down and shot your team see's his character playing The "bleedout animation", however the enemy cannot see the player squirming around bleeding out because it's not replicated over the network intentionally. When the enemy shot his opponent he just saw it as he killed him. While on the opposing team he can see his team mate down bleeding out with a chance to revive. Sorry very hard to explain lol Games like onward and population one make animations and collisions look wonky and I'm trying to prevent that. But yah. Do you think any of what I said is possible or practical . 😂

[@JustinPBarnett]

@@Mad_Luv85 Oh gotcha! Yea I can definitely help with that kind of thing. For starters, try doing your crosshair code on the LateUpdate() call instead of Update(). That may help your jittering a bit.

[@joobroobn4640]

U are amazing bro

[@JustinPBarnett]

Thank you so much! 😀

[@shimmery1210]

Hi, I don't think CharacterContorller methods should be put in the FixedUpdate. In its description, Unity says:"A CharacterController allows you to easily do movement constrained by collisions without having to deal with a rigidbody." And "It is recommended that you make only one call to Move or SimpleMove per frame."

[@JustinPBarnett]

You're correct. Character controller stuff isn't physics based. Good catch!

[@Mad_Luv85]

The new VR system has been a nightmare for me just setting up. I get its more efficient and less code but man setting this up is a pain so much errors for hours still in limbo with understanding how to make my character turn or snap turn with while in the scene and to be able to look around im on a quest 2

[@JustinPBarnett]

100% agree....OpenXR is still a baby and doesn't have a lot of the nice pre-built actions & animations that SteamVR or the OVR plugin did. Oh! and I'm covering snap turns & continuous movement in my next video on Wednesday!!

[@Fahrenheit51e]

Hi! Thank you so much for this video! It was the only one I could find that worked! I've been trying to add "Jump" to the script but my little cube just start shaking like crazy!? I added: public void onJump(InputAction.CallbackContext context) { GetComponent().velocity = Vector2.up * jumpVelocity; } Then added the Rigidbody component to the player. Now when I press play the cube starts shaking. If I disable "Character Controller" the cube stops shaking and I can jump, but I can't move... What am I doing wrong? 😭

[@JustinPBarnett]

Thanks so much! You're so welcome for the video! And you're changing the velocity directly instead of just adding to it. Try .AddForce(...) to the rigidbody instead of .velocity = ... and see if that works any better

[@Fahrenheit51e]

@@JustinPBarnett Thanks for your message! I tried with public void onJump(InputAction.CallbackContext context) { rb.AddForce(0, thrust, 0, ForceMode.Impulse); } But again if Character Controller is enabled the cube just starts shaking :\ As soon as I disable that, I can jump.. but I can't move 😅 I even tried making a new project from scratch.

[@jedoncarter8570]

Thanks man, after 3 hours of trying to figure this out the second method you provided finally worked for me. I dont know if its my Unity version or what but the "easier method" (with the player input) does not work for me at all. Note: You can also enable the entire action map instead of the particular action. More efficient according to Unity

[@JustinPBarnett]

Huh, could be your version. I updated to 2020.2.7 right before this vid. Oh cool! I’ll enable the whole thing next time. That makes much more sense. Glad you got it working!!

[@rodrigo.cs.machado]

Amazing bro! And what would it be like to make him jump using the joystick?

[@JustinPBarnett]

Using the joystick? I’d recommend using a button for jumping. But you’d add a new input action called “Jump” and then set the input to “button”’or thumb stick or whatever you want. Then reference it just like you would the move input

[@NickBaijens]

live chat ended before I finished typing this so gonna just dump it here, but in regards to creating a multiplayer hangout of the project we were taliking about at the end there: "I might, maybe not as a standalone thing, but I believe I have a VRchat account that can upload custom content so might look into that for multiplayer"

Hi! Great videos on VR. Question on actionbased input system. How to get the actionbased controllers velocity? Devicevelocity. I can track the devicevelocity in the debugger but dont know how access it in c#..Trying to make a climber function with this new input system and actionbased controllers using openxr. Anyone?

[@JustinPBarnett]

Unfortunately there isn’t a way to directly call the velocity atm. The workaround I’ve found for it is to store the last 3 positions of each controller in an array and then do a calculation on it to find the avg distance traveled / time. I’ll let you know know if I find a better way to do it.

[@Dodger5163]

@@JustinPBarnett Actually I found a way! You can access the devicevelocity thru an action in the input actions asset. I changed the haptic action to a new binding "devicevelocity" and changed the action type and control type to value and vector3. It works but I didt figure out how to add a completely new action and access that action in c#, thats why I changed the haptic action.

Hello, first of all, this channel is great and helped a lot with my VR development. I have a question related to Unity action-based input with XR development. How to differentiate actions for a particular input? for example, the joystick from the Oculus Quest 2 can be used for scrolling in the menubar but also for rotating direction when teleporting. how should it be implemented? Thanks for reading this comment :)

[@JustinPBarnett]

You'll just need to set up a new action map for whatever actions you want. So for example and action map for when you're holding a gun where the buttons will operate the gun's slide and magazine, but then swap it over to another action map for holding a steering wheel of a car

[@ItsIsaacIO]

Right Now, Joystick For Default Movement Isnt Available. Its Just Joystick Up, Joystick Down, You Get It. How Would I Do This Now?

Try changing the value you're getting. You may be on "axis" instead of "vector 2"

[@stuartrichards54]

Great stuff Justin. I'm trying to figure out how to map an action to bring up a menu (currently targeting Quest 2 build). From a UX perspective, I would assume that we would map the Menu button (the one with 3 lines), but I'm having a little trouble finding how to do that. Is it unmappable, and should I focus on another alternative button for the menu?

[@JustinPBarnett]

It's built into the XR Interaction Toolkit! You'd do "ActionBasedController controller.uiPressAction += " in the code set the event or you can add to the event from inspector as well!

I'd say use a bool variable on the hand. An "IsGrabbing" variable or something, then you can check for that to get the correct controller. Also the actions can be set to be left or right hand based on what map they're in
