A small demo application that implements an Augmented Reality teapot shooter with Unity and ARCore. You can use this application to shoot teapots in a real room. You must wait a little until it has tracked the room, and then you can start shooting by simply tapping the screen.
This demo is mostly just a modification of the HelloAR sample. The files that contain
the main logic, is in the files Assets/GoogleARCore/Examples/HelloAR/Scripts/HelloARController.cs
and Assets/GoogleARCore/Examples/HelloAR/Scripts/SurfaceManager.cs
The implementation is pretty simple: the app simply creates collision shapes from the planes tracked by ARCore, and these are used by the Unity physics engine for the collision between the teapots and the planes.
A compiled apk is provided as teapot_shooter.apk.
