OService

Multiplayer networking library for DragonRuby Game Toolkit with LAN, Steam, and GOG¹ support. Built on Unet and OSSP.

Build

LAN & ENet

• Enabled by default, can be disabled when launching OService from your app.

Steam

1. Add UNET_MODULE_STEAM=ON to build-unix or pass it to CMake².
2. Add STEAM_APP_ID=(your app id) the same way.

Windows

• Use MSVC. GCC/MSYS2 may work but hasn’t been tested recently.

macOS

1. Run build-unix.
2. Sign the extension if you plan to distribute it³.

Linux

1. Run build-unix.
2. Run patchelf --set-rpath $ORIGIN oservice.so so the Steam library is loaded from the same directory.

Usage

See documentation.

Place libraries as shown below. steam_api64.dll must be in the game root.

- "game root directory"
    - "game executable"
    - steam_api64.dll
    - native
        - linux-amd64
            - libsteam_api.so
            - oservice.so
        - macos
            - libsteam_api.dylib
            - oservice.dylib
        - windows-amd64
            - oservice.dll

Debugging

• On macOS, resign the DragonRuby app to allow attaching a debugger.
• On Linux, use LD_DEBUG=libs ./dragonruby dr-socket-unet to list missing dependencies.

Notes

¹ GOG support exists, but is untested (I do not have a dev account).
² Requires a Steamworks account.
³ Requires an Apple certificate.
