Thanks,

Hi~

I upgraded an old unity project from unity 2019.2.3/vuforia 8.3.8 to unity 2021.2.8/vuforia 10.3.2.

But the following syntax does not work.

ObjectTracker tracker = TrackerManager.Instance.GetTracker<ObjectTracker>();    

tracker.Stop(); 

CameraDevice.Instance.Stop(); 

How should I write it in vuforia 10 ?

thank you~

Hello,

My problem is that I get a null reference exception: Object reference not set to an instance of an object

with the VuforiaBehaviour.Instance.World.GetTrackedObserverBehaviours() method.

Is it possible to check if it will not return null ? If yes, how ?

I've checked the Vuforia Documentation but I didn't found anything...

Vuforia version : 10.1.4

Unity version : 2019.4.15f1

I am a bit new to unity and I am trying to create the snake game in AR. I used an image target to place the game level/map which is a simple plane with a mesh collider. And I placed my snake model on the plane and attached  Rigidbody components to each node of the snake.

Hi, I'm new in Vuforia. I have done my first project using Vuforia 9.8 and it worked well. Now I want migrate it to 10.3.2.

But when I completed the migration, I found Vuforia cannot work. The watermark didn t show. I tried to apply a new basic license, but there was still no watermark and the AR could not work.

I cannot find the solution. Please hlep me.

Hello,

So I'm new in this world of AR aswell as working with vuforia.

So here's what i want to do:

I have a cube that will rotate (every face of the cube as a color), and then after a while the cube will stop and the color facing the camare will be my target, then i have to move around the "world" and i'll have to find that color. 

Problem with object recognize

I am developing an application for HoloLens 2 using Unity(2020.3.22f1), Vuforia Engine(10.3.2) and MRTK(2.7).

The application has to recognize an object, the problem is that the object is recognized in the wrong place than it really has to be and always in different places.

This happens only if the application runs on HoloLens 2, while from the Unity editor it works correctly.

Does anyone have any idea what this could be?

Hi, I need to start a new project with object target. In the new pricing page, I see that Vuforia is free for a lot of features, but there is not the Object target recognition, not in the free version nor in the Premium version.

Is Object target deprecated?

thanks

Massimo

i was following that tutorial, and tried using free 3d model from asset store and it worked. but when i tried to use my 3d model, it didnt work.

unity version is 2020.3.22f1 , using vuforia and platform is android

I have for a long time used the Vuforia Engine for AR Creations in Unity 3D. But with the new version 10.3 came many changes that I have problems with. Especially with the new virtual buttons which I want to use to animate a a figure in my ar app. How can I do this? Are there good tutorials to integrate them into? 

Also I cant find the scribt Virtual Button Event Handler in Unity. Should I reinstall or am I missing something?
