Windows, Linux and MacOS (added support in 2.4.10, not working with ARM CPUs)! Fabric and Forge (requires Forge 37.0.69 or above).
Update 2.7.0 (Despawn Animations + GUI Physics)
You can now create custom despawn animations for physics objects and I also added physics for the GUI (just hit F6 in the menu) :D
Update 2.6.0 (Sound Effects + New Block Breaking Type)
Added sound effects and a new block breaking type which fits the cracking particles very well.
Living mobs interact now with physics.
Update 2.4.0 (Blocky Block Physics)
Added the option to not fracture blocks. Iris Shaders are now compatible with this mod (and highly recommended because the Iris mod uses Sodium which has no official 1.17 release yet and greatly improves performance, even when not using shaders).
Update 2.3.0 (Basic Item "Physics")
Added fake item physics which can be disabled via the options menu if you don't like them!
Update 2.2.3 (Ragdoll API)
Physics Mod now has a Ragdoll API for mod creators that want to add ragdoll support. More infos can be found here: https://github.com/haubna/PhysicsMod/
Update 2.2.0 (Full Vanilla Ragdoll Support)
All vanilla mobs support the ragdoll functionality now!
Update 2.0 (New Physics Engine)
Update 1.3 (Ragdolls + All Blocks supported)
What does it do?
It adds physics to mobs and blocks. That simple. You can fully customize the amount of physics and disable or enable certain parts of it for better performance on low end computers/laptops.
Download the respective mod (Forge or Fabric) and place it in your mods folder. If you want better performance I would recommend going for Fabric and Sodium (improves performance by a lot). For Fabric you will also need to download the Fabric API and place it in your mods folder.
You can customize everything under Options -> Physics Settings. Config files are located in the minecraft installation folder within the configs folder.
Visualization for some configuration options
I would like to implement wider Mod support (with other mods), fracturing depending on the material (wood, stone, sand and so on), water droplets from explosions, soft body physics for slime blocks, honey and so on.
