I am working on a video game where every single block is physically simulated and can be interacted with. Imagine if you could pick up a large body of water, and smash that into a building, which would then break apart and come tumbling down. That is just one of the many things the custom physics engine in this game will be able to do.
I still have a ways to go before going "early access", but you can follow my progress on this channel as I build out my game and physics engine. I love reading feedback and suggestions and try to incorporate those in my videos as much as possible. Many of the scenes that I simulate are based on actual material and structure requests that I read in the comments!
Some videos on this channel are really old (I've been making physics simulations for over 14 years), but I keep them around because it can be really fun to look back and see where I started.
