Turn Controllers to Hands in VR with Unity XR! Part 2 

One more thing, the above comment was off the back of having just completed part one. In part 2 I've made it to 06:50 having typed the script for ThumbValue. A bit of a head-scratcher, the thumb doesn't animate in Play when buttons are pressed. Script and compiler show no errors, animation preview pane does have a working animation. Any suggestions ? Thanks

Glad it helped! Thanks for watching. :)

Thanks!

Thanks, it solved my issue

hey @R K how are you stoping from checking with a boolean. thanks

The code in the GetInputDevice() in update or put GetInputeDevice(); in the update

Bool looking = true; If(list.count !=0) looking = false

I don't remember but that should amount to the same thing no? Just keep looking in update until the list contains something

Glad it helped

Yes, I just got these this morning when opening the project to resume the tutorial. 'Else' being the problem. Did you find a solution? PS, I'm guessing your thumb didn't work either?

Thanks! Really appreciate it. and ya I do have a discord. Novaborn#5654 if you want to add me.

Ok. I got it. When I created the animation object for the left hand, I named it LeftHand. When I duplicated the prefab of the left hand and renamed it RightHand, I also changed the name of the animation object to RightHand. Unity was not very happy about that. With a few minor tweaks, everything is working perfeclty.

Same.

anyone fix it yet?

@@seppedaems8335 I too am having this issue

@@bowler28 I asked my teacher and he has fixed the issue. using System.Collections; using System.Collections.Generic; using UnityEngine; using UnityEngine.XR; public enum HandType { Left, Right } public class XRHandController : MonoBehaviour { public HandType handType; public float thumbMoveSpeed = 0.1f; private Animator animator; private InputDevice inputDevice; private float indexValue; private float thumbValue; private float threeFingersValue; private bool inputDeviceValid; // Start is called before the first frame update void Start() { inputDeviceValid = false; animator = GetComponent(); } // Update is called once per frame void Update() { if (!inputDeviceValid) { initInputDevice(); } AnimateHand(); } void initInputDevice() { InputDeviceCharacteristics controllerCharacteristic = InputDeviceCharacteristics.HeldInHand | InputDeviceCharacteristics.Controller; if (handType == HandType.Left) { controllerCharacteristic = controllerCharacteristic | InputDeviceCharacteristics.Left; } else { controllerCharacteristic = controllerCharacteristic | InputDeviceCharacteristics.Right; } List inputDevices = new List(); InputDevices.GetDevicesWithCharacteristics(controllerCharacteristic, inputDevices); //InputDevices.GetDevices(inputDevices); if (inputDevices != null && inputDevices.Count > 0) { inputDevice = inputDevices[0]; inputDeviceValid = true; } } void AnimateHand() { inputDevice.TryGetFeatureValue(CommonUsages.trigger, out indexValue); inputDevice.TryGetFeatureValue(CommonUsages.grip, out threeFingersValue); inputDevice.TryGetFeatureValue(CommonUsages.primaryTouch, out bool primaryTouched); inputDevice.TryGetFeatureValue(CommonUsages.secondaryTouch, out bool secondaryTouched); if (primaryTouched || secondaryTouched) { thumbValue += thumbMoveSpeed; } else { thumbValue -= thumbMoveSpeed; } thumbValue = Mathf.Clamp(thumbValue, 0, 1); animator.SetFloat("Index", indexValue); animator.SetFloat("ThreeFingers", threeFingersValue); animator.SetFloat("Thumb", thumbValue); } }

No problem!

Hmmm, do you have the animation on loop? answers.unity.com/questions/204331/animation-loop.html

This is a good idea. I have a video in the pipeline already coming soon, but maybe after that one. Thanks!

This sounds like you have two files named XRHandController? or maybe you copied the same thing twice in one class? The error you posted about means there is a duplicate definition got XRHandController. So check that out. Something you can do to find it if you use visual studio is highlight XRHandController and use ctrl+shift+f to search for all text like XRHandController. VS should now show you where all your XRHandControllers are.

@@Novaborn Hi I checked but I only have one file named XR HandController. I've also went over my code again and it is exactly the same as the one described in your video but I'm not sure why all these errors are popping up.

i figured out its because c# isn't recognizing unity or unity.xr as things I can bring into the script, I still don't know how to fix it though

I had this problem before in an older version of Unity. I think what I did was go to Preferences -> External Tools. Then I made some changes there. Currently when I go to my settings in Unity, I have Visual Studio Community 2019 as my External Script Editor. Next I have Embedded packages and Local packages checked. If that doesn't work for you, you need to Google something like "using UnityEngine not defined in Visual Studio." Sorry if I wasn't more helpful. I do remember this being a pain to resolve for me.

I know that it has been a year, but I'm posting this solution for other people who might read it: Run the Visual Studio installer and click modify. This will open a menu. Add the Unity 3D module by checking the little box. Relaunch Visual Studio and everything should work

good idea

I only tested on Quest 2, but I am 95% sure this will also work for Quest 1

Next I'm doing a Beat Saber VR in Unity tutorial and a "game in one month" type of devlog.

thanks for the feedback

It was an APIs problem.

did you ever get this fixed because its happening to me
