Gone are the days when you must create a new voxel shape for every direction your block faces! With the help of this library, it can all be done with a simple function.

This mod adds some tools that help modders to more easily manipulate, create, and rotate voxel shapes in their code!

To get started with using this library, please go here: GitHub

Required Dependencies

• Fabric API
• Fabric Language Kotlin - Adds compatibility for the programming language this mod is written in

VoxLib

VoxLib is a Fabric library for Minecraft 1.19.4 that makes working with block voxel shapes less repetitive. Create a shape once, combine its pieces, rotate it for each direction, and inspect the result in-game.

VoxLib is primarily intended for mod developers. Install it when another mod lists it as a dependency, or add it directly to your development environment.

Features

• Create cuboid and common block shapes
• Combine shapes with concise Kotlin helpers
• Build shapes conditionally
• Rotate and flip shapes for directional blocks
• Simplify complex collision and outline shapes
• Cache repeated shape operations
• Display targeted outline and collision shapes in-game
• Log and compare shapes in client or server environments

Quick Example

val northShape = createCuboidShape(5, 0, 0, 11, 16, 8)

val eastShape = northShape.rotateRight()
val southShape = northShape.flip()
val westShape = northShape.rotateLeft()

Using VoxLib from Modrinth Maven

repositories {
    maven {
        url = "https://api.modrinth.com/maven"
    }
}

dependencies {
    modImplementation "maven.modrinth:voxlib:1.6.0+1.19.4"
}

Dependencies

• Fabric API — required
• Fabric Language Kotlin — required
• Mod Menu — optional; provides access to the debug settings screen

Compatibility

• Minecraft 1.19.4
• Fabric
• Java 17 or newer
• Client and dedicated server

Shape utilities work on both sides. Rendering overlays and the configuration screen are client-only.
