While Croquet itself is independent of any specific UI framework, we provide our own frameworks that build on top of it (see below).
The Croquet Microverse Builder is a tool that lets you build shared Metaverse worlds with a few lines of code. It is implemented using the Worldcore engine (see below), which sits on top of the Croquet kernel (see above). It's in open beta right now.
Worldcore is an entity-management system that sits on top of Croquet. It makes it easier to wrangle large numbers of 3d objects in a multiuser app. Watch Croquet's Chief Creative Officer, Brian, and Chief Architect, Vanessa, discuss the fundamentals of Worldcore for the Experimental Gameplay Workshop at GDC 2021.
The Croquet Virtual DOM is a high-level framework that extends the core capabilities of Croquet. It’s a set of tools for writing Croquet applications that use a browser’s DOM as multiuser interface elements. Yoshiki Ohshima gave a talk on Croquet and the live programming functionality built into the Virtual DOM Framework. The talk was in Japanese but you can turn on the English subtitles.
