FerrumC, similar to Pumpkin, which I recently posted today, is yet another Minecraft server built in Rust that released a month ago. Funny that there’s already an inside joke regarding new Rust Minecraft servers being released close to the pace of JavaScript frameworks.
Yeah world gen is one of the most difficult parts to implement since Minecraft and Mojang are very protective of that area, not to mention the monumental task of maintaining bug compatibility, especially with redstone. It’s still interesting to see parts of Minecraft being implemented in other languages.
