Coding every little aspect of a VR game would be ridiculous. That's why game developers rely on frameworks to do the heavy lifting!
Hey Patreons! You've probably been following along with each and every one of my tutorials listening to my every word (ha) and I want to steer you back in the right direction. You. Don't. Have. To. Code. Everything. There are glorious frameworks out there to download that we can use as a base layer for our games. Most of these have all the interactions you could ever need for your game! As a solo or indie developer, you're not going to want to or be able to code every line in your game. I highly encourage you to check out one of these frameworks and play around in it. Make a game in a week or so and let me know in the Discord how it goes!
