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** 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. ### 🛠️ **Developer API** Create custom physics objects, control rendering, manipulate bodies, and extend the system. Documentation can be found [here](https://xi-mx-ix.github.io/velthoric-docs). ### 🎯 **Testing Commands** --- **`/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] ``` ### 🔧 **Included Tools** * **PhysicsGun** – Pick up, move, rotate, and yeet objects. * **Magnetizer** – Pull or push objects where you aim. * **BoxThrower** – Spawn and launch boxes instantly. * **ChainCreator** – Connect two objects (or one to the ground) with a chain. ### 💻 **Supported Platforms** - 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**. ### ⚠️ **Bug Reports & Mod Compatibility** Found a bug, crash, or an incompatible mod? Please report it on the **issue tracker**:
