Migrate from UnityARKit to ARFoundation


I see that Unity AR Kit plugin has been deprecated. I have been using Unity ARKit plugin and now have to move to ARFoundation. My primary usage of ARKit plugin is with ARWorldMap.

So far i have been using Unity 2018.3.14f1 but it looks like I have to use Unity 2019.1+ for ARFoundation.

Is there any migration guide or can anyone give me recommendations. I would also like to know where to start ARFoundation?

Thank you,

Good question!

Millions of Unity developer hours could be saved here if there's either an automated converter (like TextMeshPro package updates) or at least a very clear guide for upgrade.

Thanks @ina . I have several request of such kind for no response. My ARFoundation setup is like this :

Unity Version : 2019.1.6f1

ARFoundation Version : preview.2 - 2.2.0

ARKit Plugin : Preview 5 - 2.1.0

Device iOS : 12.+

XCode Version : 10.2.1

What is yours? Maybe we could help each other.

Theres a few fundamental conceptual changes that would make automatic conversion a bit tricky.

Manually converting over only takes an hour or two though… have done this recently on a project and it wasn’t too painful, just be mindful of the change in concepts.

@enhawk Thank you for the reply. I have been searching for 3 elements for the past 2 weeks. Could you please help me locate these? I would highly appreciate it.

ARFoundation has auto resume. The nearest approximation I think is this:

I think tracking reason has gone away, but theres a bunch of things you query the system state on.
