Velthoric Physics Mod
💥 What’s this mod all about?
Velthoric brings high-performance physics to Minecraft using the full Jolt Physics engine via JoltJNI. Move, collide, and interact with rigid and soft bodies, ropes, and cloth, all with persistent worlds and a powerful developer API.
⚡ Core Features
- Rigid & Soft Bodies – Full simulation of solid and deformable objects.
- Narrow & Broad Phase Collisions – Efficient collision detection for all objects.
- Constraints – Support for joints and other physics constraints.
- Shapes – Various collision shapes supported.
- Raycasting – Detect and interact with objects using rays.
- Region-Based Persistence – Terrain and physics objects are saved per region, keeping their state consistent when you reload the area.
🛠️ Developer API
Create custom physics objects, control rendering, manipulate bodies, and extend the system.
(Documentation coming soon!)
🎯 Testing Commands
/vxsummon
Spawn built-in and custom objects: boxes, ropes, cloth, marbles and more.
Also works with any objects registered via the API.
/vxtest
Quickly create predefined setups for dev & debugging.
Includes chained boxes, configurable soft bodies, box grids, and more.
/vxkill @x[...]
Remove physics objects matching a selector.
You can target objects by type
, bodytype
, distance
, limit
, and sort
.
