VRC world prefab by me and F4celess. Still WIP, but it's playable, unlike other AirHockey prefabs and worlds.
Just drag *.unitypackage into your world project, than drag prefab into your scene. For updating, you also drag *.unitypackage into your world project, than rightclick on AirHockey on your scene -> Prefab -> Replace and select updated prefab.
In GameManager script, you can change max amount of points before game over. Default is 7.
LightSync, tested on 1.5.0, but you should install the latest version avaliable in your VCC.
TextMeshPro, Unity will prompt you to install it if it isn't.
