just begin to code/work on unity.
No big trouble to set some camera move or launch animation on standalone plateform.
But when I try Oculus go ... I want to get the same "on click' I've got on standalone plateform. Ideally I would make a gaze pointer timed, which avoid joystick.
First : Do you know how to display what you see on the Oculus on unity (https://www.youtube.com/watch?v=TektJroMwxY at 9:40 for example) ?
And then How could I simply implement a gaze pointer click ? I try the Oculus unity integration (https://developer.oculus.com/downloads/package/unity-integration/) UI scene but there is too many code to understand quickly everything.
Many thanks for your help,
Axel
First of all:
Interesting stuff is not quickly to learn
Anyway, you need to know that Oculus gaze point do not work as the typical mouse-click. You need to raycast from your camera to stuff (with attached colliders or build some system) to know if you are clicking on it.
Watch deeply on VrInteractiveItem class, as it's how oculus mainly works.

After I build my Unity project and send it to the Hololens, I have the following problem:
The splash screen appear followed by a debugging window on the bottom. In the background is a white net. However, you can't see any game objects. I've tested a lot but haven't found a solution for that. Visual Studio does not display any error messages. What I've looked at roughly:
These are my modules. Im using the 2019.4.22f1 version of Unity and the MRTK Foundation Toolkit 2.7.2.
My build settings
My project settings
I tried to place the objects in the middle of the camera and changed the colors.
MRTK settings I haven't changed anything most of the time
Main camera settings
My scene
When i start the scene i get this error in the console. I dont know if this has anything to do with my problem
i have two possible solutions (no guarantee)##
you could spawn the objects on input directly in front of the
camera, add a debug.log("object in front of you"); so you can find
the issue.
If this doesnt work i would try to test differnet types of materials
like you do with HDRP.
if this does not work either i probably cant help you out now.
It seems like your GameObject is too far to be hidden behind by the mesh. Please make the spatial mesh invisible by setting the Display Option property of Spatial Mesh Observer Setting to None, this item can be found under the Spatial Awareness profile of the MRTK profile.
I use Holographic Remoting Player to project the unity uwp program to HoloLens. I can get the unity picture on HoloLens, move around to move the field of view, have the hand laser and air tap working well, but the hand joint visualization doesn't show up.
The player setting is ok. And I have followed the troubleshooting steps in this link, everything is ok, but the hand joint still doesn't work.
https://microsoft.github.io/MixedRealityToolkit-Unity/Documentation/Tools/HolographicRemoting.html#msbuildforunity-package-import-via-writing-into-the-packagemanifest
I have tried in Unity 2019.2.4 and 2019.4.1, both the same result. Is there anything misconfigured I need to check?
According to this document, the hand tracking profile has been updated to allow for setting the hand joint visualization to: Nothing, Everything, Editor or Player. It meaning it is possible to turn on/off hand joint visualizations while in the editor or in the device or both. So it might be a good idea to double check this field in your MRTK profile and the following way is worth trying:
Click the MixedRealityToolkit object in the Hierarchy window, and then navigate to Input->Hand Tracking in Inspector window, find HandJointVisualizationModes field and set to Everything.

I'm a unity vr game and I made a model for my vr hands and I heard to apply the model to your vr hands you just drag the model on to the xr Controller compment > Model Prefab. So I did that and then I tested my game. And my hands where far away from me and not linked to my controllers. Also my hands were really big to
Troubleshooting steps I took
I tried deleting the "Left hand" and "Right hand" In the Hiearchy and than made the left hand and right hand again and than added the xr controller compement and then dragged the hand model to the model prefab.
I tried delting the model and making a new one. This did not work
Here is my unity project if you want to take a look at my problem. https://drive.google.com/drive/folders/1XfQ1-_GGctwLSzYa2niW_6o1yJ_7IcQF?usp=sharing
I probabley did a really bad job explaing this. Sorry for any spelling errors
I have been trying to get a very simple demo of a native Unity UI canvas working with VR.
I have read the oculus blog post here: https://developer3.oculus.com/blog/unitys-ui-system-in-vr/ but i need to use the native unity UI as i want to redistribute the code without license worries.I followed this tutorial https://unity3d.com/learn/tutorials/topics/virtual-reality/interaction-vr?playlist=22946 and downloaded the unity vr samples project from the asset store. In this they provide some scripts to place on the camera (VRInput and VREyeRaycaster) and some scripts to place on the target object (VRInteractiveItem and ExampleInteractiveItem).
When i apply the target scripts to a regular GameObject in the scene (e.g. a cube) the raycast works fine and the appropriate calls are made when fire1 is activated. When i try and do this for a canvas object (e.g. a button) - no hit is detected. I have tried placing the two target scripts (VRInteractiveItem and ExampleInteractiveItem) on the canvas, the image containing the button and the button itself and none work. What am i doing wrong? Why would it work on a regular gameobject and not on a UI canvas? I have made sure all my canvas elements have their raycast target boolean property ticked
EDIT:
It seems to work when i attach a box collider to the UI element, is this required? i thought it should just work with a GraphicsRaycaster attached. but the configuration below doesn't work (when box collider is disabled and graphics raycaster is enabled)
This is what is on my players camera:
I dont have a problem using box colliders if i have to but i wanted to take advantage of the UI buttons changes in highlighted and pressed color properties
In Unity raycasting works only with game objects having colliders. Raycast returns true when it hits a collider. Without colliders there is nothing the ray can hit.
Unity Physics.Raycast documentation
I believe, for anyone just seeing this for the first time, a potential reason it is not working is because the canvas from the above picture is using a "Graphics Raycaster" element and not an "OVR Raycaster" element. The OVR Raycaster is meant to replace the graphics raycaster to connect Oculus to Unity UI.
If you want to use the unity's UI in VR you might want to take a look at this asset: VRTK
There are some examples of VR UI using controllers or camera targeting.
Go to your canvas, you should have an option that is "Plane Distance" it's set to 100 , I change it to 0.5 and it works quite well.
When I add an OVRPlayerController into a Unity3d scene and build and run the scene for the GearVR the built-in touchpad spins the camera around the vertical axis, which is redundant with head tracking. What do I need to change so that the touchpad instead allows the camera to move forward and backward, as if walking? Is there a thorough tutorial?
The Oculus SDK 0.4.3 comes with the support for the GearVR Samsung GamePad.
All you need to do:
import the SDK.
overwrite the projectsettings folder of your project with the one that comes with the SDK.
add the overplayercontroller to your scene.
add a gameobject below the overplayercontroller e.g. plane, quad... this will act like the ground (keep the player from falling)
add a collider to the gameobject e.g. mesh collider
then once you run it you will see that you can move around using the gamepad as well as turning the came around the vertical axis...
basically use any first person shooter tutorial for Unity3D and because the Oculus SDK comes with support for the gamepad you can quickly do this...
