Jenga Mod

Every piece measures 1×3×9 blocks and is built from stripped logs, with successive layers turned in alternating directions, the way the physical game arranges them. A tower is assembled from pieces chosen in the Open Jenga options menu, and the physics follow the behaviour of the Sable sub-level system: every piece is its own sub-level that falls, tips and collides independently of the others.

Grabbing a piece follows the view and its scroll rotation, and the grab dispatches to whichever sub-level the player is looking at. Large towers take a moment to build, since one layer is placed per tick, and a stack setting of 999 is intentional. Running a stack drop is a way to see the full tower fall, while pulling one piece with an empty hand eases out and can bring the whole structure down. The mod is recreated from a Systemzee video that showed Jenga with realistic physics.

Jenga Mod depends on Sable for its physics, and the Fabric build runs on client and server, so the server and every player need it. Files are published for Fabric only, for 1.21.1, with 1.1.0 as the latest file. The mod is released under a custom license and is not open source; its source code and issue tracker are public.
