Realistic Physics Mod adds a new physics system that changes how things move and break in your world. In normal Minecraft, blocks can float in the air, but this mod makes them obey gravity. Now you can see caves collapse, structures crumble, and mobs fall in a more believable way.
Features:
Mob Physics
- All vanilla mobs now have interactive ragdoll physics when they fall.
- Mobs can be set to fracture into many small pieces.
- A “blocky” mode splits mobs into their individual body parts.
Block & Item Physics
- Blocks can crumble and break apart into smaller pieces.
- Watch as caves and other structures collapse realistically.
- Items no longer float when dropped, instead falling to the ground with physics.
World Physics
- Change the world’s gravity to simulate being on the Moon, Mars, or other planets.
