💥 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.

The entire system is built on a highly performant Structure of Arrays (SoA) architecture to handle thousands of objects efficiently.

• Rigid & Soft Bodies: Full simulation of solid objects as well as deformable things like cloth and ropes.
• Drivable Vehicles: Cars and motorcycles with working suspension and wheel physics.
• Collision Detection: Efficient broad and narrow phase detection that supports complex shapes and convex hulls.
• Humanoid Ragdolls: Create physical ragdolls from living entities.
• Buoyancy: Objects float in water and lava based on their volume and density.
• Block Conversion: Convert any standard Minecraft block into a dynamic physics object.
• Constraints: Connect bodies using joints and other physics constraints.
• Raycasting: Precise ray and shape casting against the physics world.
• Persistence: Physics bodies are saved with the world and synchronized efficiently between server and client.

Create custom physics objects, control rendering, manipulate bodies, and extend the system.
Documentation can be found here.

/vxsummon
Spawn built-in and custom objects: boxes, ropes, cloth, marbles and more.
Also works with any objects registered via the API.

Test Vehicles:
You can spawn a test car or motorcycle that you can drive using:

/vxsummon velthoric:car ~ ~ ~
/vxsummon velthoric:motorcycle ~ ~ ~

The seat is visible when you press F3 + B.

/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.

Example:

/vxkill @x[type=velthoric:box,limit=5,sort=nearest]

• PhysicsGun: Grab, move, rotate, and throw objects around.
• Magnetizer: Push things away or pull them closer to you.
• BoxLauncher: Spawn and shoot boxes wherever you want.
• RagdollLauncher: Launch ragdolls and watch them tumble.
• ChainCreator: Connect objects together or tie them to the ground.

⚙️ Customization: Just press TAB to configure your tools. You can adjust settings like strength, range, and more to fit your style.

• Windows x86_64
• Linux x86_64
• Linux Arm64
• MacOS x86_64
• MacOS Arm64

Note: All other platforms (e.g., 32-bit systems, Android) are not supported and will crash.
