I can build games in VR with Unity, only because I bought an asset which its creator constantly updates. I never did learn to code it. 😕
I think the asset was called Autohands? And it works very well.
However, I am so over not actually programming the game, myself. My deal is that I don't even know how to make the VR fingers move in Unity- my hands might as well be cubes, or programmed by someone who actually does know what they're doing.
