Bookshelf is a user-friendly modular library datapack, crafted to assist map makers in effortlessly implementing intricate systems within their maps.

Read and write entity positions and rotations as scoreboard values.

Create smooth curves from control points, with Bézier, Catmull-Rom, B-Spline, and Hermite interpolation.

Mathematical operations beyond what vanilla commands offer.

Execute commands based on what an entity is looking at.

The complete Bookshelf library in a single datapack: dozens of modules covering blocks, hitboxes, math, raycast, and more.

Assign unique numeric IDs to entities.

Manipulate blocks with their states and NBT, and combine block properties.

A collection of all core modules, meant to ship with your datapack.

Cast rays to detect block and entity hits, with voxel-accurate collisions.

Manipulate strings, which vanilla commands barely support.

Vector math for datapacks, including rotations and coordinate conversions.

Combine scores and NBT data into a single structured dump.

Attach click and hover events to Interaction entities.

A collection of modules with structure files to use in your world.

Manipulate colors and convert them between formats.

Log messages to chat with varying levels of severity.

Manipulate integers as sequences of bits.

Run a function over every position in a shaped region, spread across ticks.

Access the real-world system time from inside a datapack.

Link entities together so their positions and rotations stay synchronized.

A collection of modules to help you debug your datapack while you build it.

Build scoreboard sidebars with formatted, updatable content.

Schedule commands that remember which entity and location triggered them, and can be cancelled.

Access biome, weather, and time-based conditions.

Move entities along a velocity vector, with collision handling.

Work with the hitboxes of blocks and entities.

Read and modify player XP levels, and set the progress bar by percentage rather than by points.

Read and modify player health, and give entities a lifetime.

Generate random values, weighted picks, and noise patterns.

Pre-built tree structures with multiple variations.

Manipulate collections with a full set of functional operations.
