RealmCrafter: Community Edition

The open-source MMORPG engine, reborn.

Build vast online worlds without writing a renderer, a netcode stack, or a database layer from scratch. RCCE picks up where the original RealmCrafter left off — modernized, cross-platform, community-driven, and free forever.

RealmCrafter was one of the earliest tools that let solo developers and small teams build real MMORPGs — persistent worlds, characters, quests, NPCs — without rolling their own engine. Then it stopped being maintained. The community refused to let it die.

RealmCrafter: Community Edition (RCCE) is the actively-developed continuation. Same accessibility. New foundations.

• Game Engine — A complete client/server runtime for building 3D MMORPGs.
• Project Manager — A visual launcher that creates, configures, builds, and packages your game.
• World Editor (Architect) — Place terrain, meshes, NPCs, spawn points, and quest triggers.
• Scripting System — Familiar BlitzBasic-style game scripting (Server Data/Scripts) — no C++ required to ship a game.
• BlitzForge Compiler — Our modernized Blitz3D toolchain, vendored at compiler/BlitzForge, with cross-platform Mach-O / PE output.
• Networking + Persistence — RCEnet networking and SQL/MySQL backends out of the box.
• VS Code Extension — Syntax highlighting, build, debug, and test workflows for the Blitz language (extras/vscode-blitz-forge).
• Sample Content — A populated default project so you can launch a working world in minutes.

1. Grab the latest build for your OS from Releases.
2. Unzip it.
3. Launch Project Manager (Project Manager.exe on Windows, Project Manager on macOS).
4. Open the bundled sample project, hit Run Server, then Run Client.

macOS users — alpha. RCCE produces native Apple Silicon binaries via BlitzForge's macOS port, which is currently alpha: the runtime path is incomplete, many language and standard-library features are not yet wired up, and breakage is expected. Use the macOS build for development and feedback, not for shipping a game. See macOS Apple Silicon notes for the current source-build flow and compatibility caveats.

git clone --recurse-submodules https://github.com/RydeTec/rcce2.git
cd rcce2

Forgot the submodules?

git submodule update --init --recursive

Windows:

compile.bat            :: build engine + tools
compile.bat -b         :: also rebuild the BlitzForge toolchain
publish.bat            :: produce a redistributable release

macOS (Apple Silicon):

./scripts/bootstrap_macos.sh    # one-time toolchain setup
./compile.sh -b                 # build BlitzForge (blitzcc + runtime/linker)
./compile.sh                    # build engine + tools
./test.sh                       # compile the Blitz test suite
./publish.sh                    # produce a redistributable release

Useful flags (both platforms): -b rebuild BlitzForge, -e skip engine, -t skip tools.

• Getting Started — your first project
• macOS Apple Silicon Notes — source-build steps, release notes, and alpha caveats
• Module Reference — engine APIs
• Format Reference — file formats and conventions
• RealmCrafter Wiki — legacy gameplay and editor docs
• BlitzForge — compiler internals and language reference

Docs are a work in progress. Improvements are one of the highest-leverage ways to contribute — see below.

• ✅ Cross-platform build scripts (compile.sh, publish.sh, bootstrap_macos.sh)
• ✅ ARM64 code generation in BlitzForge
• 🚧 macOS arm64 native runtime (Mach-O, no Wine/Rosetta) — alpha, not production-ready
• 🔄 Filling in the macOS runtime to reach feature parity with the Windows runtime
• 🔄 Continued modernization of the rendering and audio backends
• 🔄 Documentation overhaul
• 🔮 Linux runtime (community interest tracked in Discussions)

We welcome contributors at every level — players reporting bugs, scripters polishing the default project, artists improving sample assets, and engine developers landing C++ and Blitz changes.

1. Fork or clone, then branch from develop.
2. Make focused changes (small first PRs are encouraged).
3. Run test.bat — tests run automatically on commit; they must pass.
4. Open a PR targeting develop. Releases are PRs from develop → master.

RCCE stands on the shoulders of:

• The original RealmCrafter team — for the vision.
• Blitz Research and the BlitzBasic / Blitz3D community — for the language that powers it.
• Everyone who kept the forum alive while the project was dormant.
• Every contributor who has filed a bug, opened a PR, or shipped a tutorial.

RealmCrafter: Community Edition is a community-maintained continuation of the original RealmCrafter project. Licensing for individual subsystems (engine source, vendored libraries, ReShade, FastExtension, sample content) follows the licenses shipped alongside each component — see the relevant files in extras/ and submodule directories.
