Unity 3D XR-tools Started pack.
Intro
This is an initial Unity 3d package that already contains all the necessary packages to start developing in VR. It works on Unity 2021.3.X and latest versions. Although, Future versions of XR-Tool kit might change the API and the interactions may not work.
Make sire you have unity 3d installed in you local machine
Download the package and unzip it.
Open Unity Hub and select the option "Add project from disk"
The first loaded scene should be inside a room.
I created a Prefab containing all the XR scripts needed to run VR on your machine. It is located in the folder Prefabs -> XR Chracter. You only need to drag and dropp this Prefab in the scene and you will have VR with basic interactions.
If you run the scene you will be posed in front of a tennis racket and a tennis ball. You canuse the right trigger button to grab those items and throw them around the room.
