Need to add a demo in

[BastiaanOlij]

Just a reminder to ourselves, need to add a small demo project in similar to other plugins so people can see how to set things up.

@BastiaanOlij Can you port the demo project you were using for the first ARCore PR to this plugin?

I think thats a good starting point, let me add it in and we can start making it work

Plugin is broken in the demo project after ./gradlew assemble is done successfully. In Godot 4.3:

Similar issue on Godot 4.2. For example, var arcore : ARCoreInterface in line 6 of ARCoreInterface.gd does not have any class called ARCoreInterface.

However, plugin works when exported to an apk and ran on the phone, though of course without camera access which I know is a WIP.

We are still in the process of adding support for ARCore and are not quite done yet
