## Built on WorldsAdriftReborn

This project is built on the open-source **WorldsAdriftReborn** project
(<https://github.com/WAReborn/WorldsAdriftReborn>), used under the MIT License (see `LICENSE.md`; the copyright notice
"Copyright (c) 2025 Worlds Adrift Reborn Contributors" applies to their code).

Their work, from August 2021 to January 2026, by **sp00ktober, mmjr-x, Cat, BluuWasTakenAlt, TheSpookyCat, kroney2,
killzoms, TheLastOperator, IGotzCheeze, Geoffrey Everaert, Viktor Ferenczi, ThisBeMe and Jesper Appelberg**, provided the
foundation this project started from:

- **The SpatialOS replacement** (`WorldsAdriftRebornCoreSdk`): a native library that stands in for Improbable's
  SpatialOS worker SDK the game calls, carrying its operations (entities, components, authority, updates) over ENet with
  protobuf messages.
- **The client mod framework** (`WorldsAdriftReborn`): the BepInEx/Harmony plugin and its original patches that point the
  game at self-hosted services instead of the official ones.
- **The login and character server** (`WorldsAdriftServer`): the original HTTP server for sign-in and character creation.
- **The game server foundation** (`WorldsAdriftRebornGameServer`): the ENet server loop, the join sequence that loads a
  client into the world, component serialization through the game's own component code, the update-handler structure,
  and basic player state (clothing, the glider).

At the point this project forked, their code could log a player in and load them into the world with that basic state.

## What this project added

Everything else was written for this project, starting October 2026, including: the Haven tutorial and its exit;
real per-player accounts and saved characters on the login server; character and world saving (with backups and save
guards); trees, chests, loot, databanks, salvage and crafting fixes;
the tier 1 island layouts with surface and hanging metal deposits and atlas shards; the shipyard, ship frames, decks,
ship parts and the Shipbuilding Tool; flight, docking, island collisions, crash damage and repair; death and respawn;
inventory operations (delete, split, merge, pending items); multiplayer (per-connection routing, players seeing each
other, a shared world, entity removal); client stability and log fixes; and the launcher.

In the line-by-line history of the current code, this project accounts for about 60% of the source and the original
project for about 40% (most of the SpatialOS replacement and client mod framework, and about a fifth of the game server).

## Other credits

- **Worlds Adrift** is a game by **Bossa Studios**. This is an unofficial community project; it does not include or
  distribute the game's files - players use their own copy, downloaded with their own Steam account.
- **DepotDownloader** (SteamRE, GPL-2.0) downloads each player's own copy of the game.
- **BepInEx** (LGPL-2.1) and **HarmonyX** (MIT) load and patch the game.
- **ENet** (MIT) carries the network traffic.
- Community research notes by **DoubtfulHermit** were used as a source of facts about the original game (no code was
  copied from them).
