# Rivencraft
Rivencraft is a clean, incremental port of the ideas and gameplay of
[Mystcraft Legacy](https://github.com/Mystcraft/Mystcraft-Legacy) to Minecraft
1.21.1 on NeoForge.
The bootstrap and books/linking milestones are complete. The project currently
provides functional Linking Books and temporary vanilla-dimension Descriptive
Book destinations with generated Return Links. Age generation, symbols,
instability, and writing mechanics have not been ported yet.
## Linking Book
Craft a Linking Book from a vanilla book and an ender pearl, then use it in the
air. An unbound book opens a screen where it can be named and bound to the
current location. A bound book opens its destination screen and travels when
its preview panel is clicked. The destination is stored on the item and
survives inventory and world saves. Travel only succeeds if the target
dimension is loaded and a non-fluid, passable landing position can be found
nearby.
Right-click an empty vanilla lectern with a Rivencraft book to convert it into
a Book Stand and place the book on it. Use a Linking Book on the stand by
right-clicking with an empty hand. Sneak-right-click with an empty hand to take
the book back and restore the vanilla lectern. Breaking a Book Stand drops both
the stored book and a vanilla lectern.
Bound Linking Books request a server-validated 18-by-18-by-18 snapshot around
their destination. The book keeps its target-centered close-up framing as a
rotating Ponder scene on the left page, backed by the
destination biome's sky color. The snapshot is visual only; the server
independently validates every link.
## Descriptive Book
Until generated Ages arrive in Milestone 3, written Descriptive Books resolve
deterministically to the Overworld, Nether, or End according to their Age UUID.
The Rivencraft creative tab includes one sample book for each. Linking creates
a bound Return Link to the exact source position and orientation. Descriptive
Book destinations additionally require solid footing beneath the player. If
their recorded arrival is unsafe, they search nearby terrain for a footed spot.
## Requirements
- A Java 21 JDK
- Minecraft 1.21.1
- NeoForge 21.1.251 or newer in the 21.1 line
- Ponder 1.0.82 for Minecraft 1.21.1 (client)
## Build and run
```shell
./gradlew build
./gradlew runClient
```
The built mod is written to `build/libs/`.
## Versioning
Rivencraft versions use `x.y.z`:
- `x` changes for a major public release.
- `y` changes when a development milestone is completed.
- `z` changes for iterations within the current milestone and for bug fixes.
The patch component resets to zero when a milestone is completed. For example,
milestone 2 development follows `0.1.1`, `0.1.2`, and so on; completing that
milestone produces `0.2.0`.
## Porting approach
Mystcraft Legacy targets Forge for Minecraft 1.12.2. Rivencraft therefore
ports one subsystem at a time onto current registries, codecs, data packs, and
NeoForge APIs instead of importing the legacy source tree wholesale.
See [docs/PORTING.md](docs/PORTING.md) for the initial roadmap and provenance
rules.
