Animators stop working after Unity and Vuforia Update

February 12, 2020 - 1:39pm #1

We have an Augmented Reality App built using below stack, which has iOS and Android versions. Tech stack

Unity 5.3.5f

Vuforia for Unity 6.2.6

C# Scripting

Xcode 7.3.1

Android SDK version 22

At the moment Google had the App removed from the Google Play Store due to a new policy violation for an AR App. Google now require a warning message available for users to be aware of their surroundings while using any AR apps.

Hance we included this message in our app and rebuild using the same old stack and tried to re-submit to Google Playstore. Unfortunately it failed to accept the new build due to an API version error. Google requires a minimum API version of 29.

To support this API level we had to upgrade Unity version to 2019.2.17f1. After that we were facing issues with Vuforia 6.2.6. So we have upgraded Vuforia to 8.5.9. After doing that I had to go through all my AR Markers and use new Vuforia Image Markers.

But after that even though the AR scene appears when AR marker is detected, None of the Unity Animators are working.

Also the Marker detection take way longer compared to Old Vuforia version. With Vuforia 6.2.6 detection is pretty much instantaneous, where with Vuforia 8, it takes 3-5 seconds to detect the marker.



Please help me to resolve above issues.

Hi,

Between Vuforia 6 and 8 a lot of things have changed. Below is a guide on migrating from different versions:

https://library.vuforia.com/content/vuforia-library/en/articles/Solution/How-To-Migrate-a-Unity-Project.html

Coming back to your issue of Animations not triggering on target found. Events can be triggered using OnTrackingFound() from the DefaultTrackableEventHandler script.

In regards to the detection time, could you please confirm the feature being used? and also device + os?

Thank you.
