Additional flavors include:

Documentation

Documentation is available here and there is the project's Wiki page here.

You can also check out the Search Help section inside Godot Engine after compiling it with GodotSteam.

Feel free to chat with us about GodotSteam on the CoaguCo Discord server.

Current Build

You can download pre-compiled versions (currently v3.10.2) of this repo here.

Version 3.10.2 Changes

  • Removed: not logged in as error condition in steamInit function

Known Issues

  • Using MinGW causes crashes. I strongly recommend you do not use MinGW to compile at this time.

Quick How-To

  • Download this repository and unpack it.
  • Download and unpack the Steamworks SDK 1.52; this requires a Steam developer account.
  • Download and unpack the Godot source 3.x.
  • Move the following to godotsteam/sdk/ folder:
    sdk/public/
    sdk/redistributable_bin/
  • The repo's directory contents should now look like this:
    godotsteam/sdk/public/*
    godotsteam/sdk/redistributable_bin/*
    godotsteam/SCsub
    godotsteam/config.py
    godotsteam/godotsteam.cpp
    godotsteam/godotsteam.h
    godotsteam/register_types.cpp
    godotsteam/register_types.h
  • Now move the "godotsteam" directory into the "modules" directory of the unpacked Godot Engine source.

    • You can also just put the godotsteam directory where ever you like and just apply the custom_modules=.../path/to/dir/godotsteam flag in SCONS when compiling. Make sure the custom_modules= flag points to where godotsteam is located.
  • Recompile for your platform:

  • When recompiling the engine is finished do the following before running it the first time:

    • Copy the shared library (steam_api), for your OS, from sdk/redistributable_bin/ folders to the Godot binary location (by default in the godot source /bin/ file but you can move them to a new folder).
    • Create a steam_appid.txt file with your game's app ID or 480 in this folder. Necessary if the editor or game is run outside of Steam.
  • The finished hierarchy should look like this (if you downloaded the pre-compiles, the editor files go in place of these tools files, which are the same thing):

    • Linux 32/64-bit
    libsteam_api.so
    steam_appid.txt
    ./godot.linux.tools.32 or ./godot.linux.tools.64
    
    • MacOS
    libsteam_api.dylib
    steam_appid.txt
    ./godot.osx.tools.32 or ./godot.osx.tools.64
    
    • Windows 32-bit
    steam_api.dll
    steam_appid.txt
    ./godot.windows.tools.32.exe
    
    • Windows 64-bit
    steam_api64.dll
    steam_appid.txt
    ./godot.windows.tools.64.exe
    
  • Lack of the Steam API DLL/SO/DyLib (for your respective OS) or the steam_appid.txt will cause it fail and crash when testing or running the game outside of the Steam client.

    • NOTE: For MacOS, the libsteam_api.dylib and steam_appid.txt must be in the Content/MacOS/ folder in your application zip or the game will crash.
    • NOTE: For Linux, you may have to load the overlay library for Steam overlay to work:
    export LD_PRELOAD=~/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so;~/.local/share/Steam/ubuntu12_64/gameoverlayrenderer.so
    
    or 
    
    export LD_PRELOAD=~/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so;
    export LD_PRELOAD=~/.local/share/Steam/ubuntu12_64/gameoverlayrenderer.so;
    

    This can be done in an .sh file that runs these before running your executable. This issue may not arise for all users and can also just be done by the user in a terminal separately.

From here you should be able to call various functions of Steamworks. You should be able to look up the functions in Godot itself under the search section. In addition, you should be able to read the Steamworks API documentation to see what all is available and cross-reference with GodotSteam.

  • When uploading your game to Steam, you must upload your game's executable and Steam API DLL/SO/DyLIB (steam_api.dll, steam_api64.dll, libsteam_api.dylib, and/or libsteam_api.so). Do not include the steam_appid.txt or any .lib files as they are unnecessary.
