ARSubsystemManager issue

Hi everyone,

I'm actually following this tutorial https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@1.0/manual/cpu-camera-image.html to zoom in and out in my AR app.
Unfortunately I can't figure out how to make the ARSubsystemManager class work. I've tried to import the UnityEngine.XR.ARFoundation namespace as suggested in the documentation but it still doesn't work.

Any help would be appreciated

 

I spent a while being confused by this, but I believe this is because the class has been removed. Check the updated documentation here: https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@1.5/manual/ and the migration guide: https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@1.5/manual/migration-guide.html

 

Yeah, you're right. Thanks for your help

 

so how to using systemStateChanged in ARSubsystemManager?
