physics blocks mod
by nekos_gf
Physics Blocks is a Fabric magic mod that gives ordinary Minecraft blocks simulated physics, so placed blocks fall, collide and bounce.
What it does
Blocks converted by the mod become physics objects that interact with the world realistically: they fall, collide with terrain and other blocks, react to their surroundings and keep their momentum after impact. The simulation is driven by the built-in Rayon physics engine, which the mod embeds rather than requiring separately.
A set of tools lets a player control blocks directly. Some tools propel blocks forward fast, using a burst of explosive power, and a heavy swing can hit physics blocks and send them flying across the world. Gravity-affected projectiles smash terrain and objects with realistic momentum, so the same world becomes a sandbox for experiments.
Installation needs Fabric API. The mod is published for Fabric only, with a single release for 1.21.11. Servers that run it need every player to install it too. The code is not open source and is released under All rights reserved.
Key features
Physics conversion
Ordinary blocks can be turned into simulated physics objects that fall and collide with the world.
Block control tools
Several tools control blocks, with some propelling them fast using a burst of explosive power.
Bouncing blocks
Blocks bounce and ricochet after impact, keeping their momentum so each shot ends unpredictably.
Creative Mode tab
A dedicated Creative Mode tab collects the physics tools in one place for quick access.
Embedded physics engine
The Rayon physics engine is built into the mod, driving the collisions and movement of converted blocks.
