Additional flavors include:

Documentation

Documentation is available 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.

Known Issues

  • Using MinGW causes crashes. I strongly recommend you do not use MinGW to compile at this time.
  • As of Steamworks SDK 1.53, you cannot compile with previous version of GodotSteam (3.11.1 or earlier) due to a code change in the SDK.
    • Using Steamworks SDK 1.53 or newer, you must use GodotSteam 3.12 or newer.
    • Using Steamworks SDK 1.53 or earlier, you must use GodotSteam 3.11.1 or earlier.

"Quick" How-To

1a. Downloading

By far the easiest way to use GodotSteam is to download our pre-compiled editors and templates; especially good for folks who don't want to set up the tools for compiling and just want to get going.

At this point you can skip all the following steps and check our our tutorials to learn more about integrating Steamworks or just explore the SDK!

1b. Compile Yourself

For those of you who are comfortable compiling or want to give it a shot, here are some steps to follow.

  • Set your system up for compiling based on Godot's recommendations / required tools.
  • Download and unpack the Godot source 3.x.
  • Acquire the GodotSteam source either by downloading it here or cloning the repo:
    • Download this repository then unpack it into a folder called godotsteam inside your Godot Engine source code /modules folder.
      • You will have to create the godotsteam folder and it must be named exactly this.
    • Alternatively, clone this repository into your Godot Engine source code /modules folder
      • Use git clone https://github.com/Gramps/GodotSteam.git godotsteam
  • Download and unpack the Steamworks SDK 1.55.
    • This requires a Steam developer account.
    • Please see "Known Issues" above about versions.

2. Setting Up the SDK

Move the following from the unzipped Steamworks SDK to the /modules/godotsteam/sdk/ folder:

    sdk/public/
    sdk/redistributable_bin/

3. Double-Checking Folder / File Structure

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

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 the godotsteam folder is located.

4. Compiling Time

Recompile for your platform:

  • For editors: scons platform=<your platform> production=yes tools=yes target=release_debug
  • For debug templates: scons platform=<your platform> production=yes tools=no target=release_debug
  • For release templates: scons platform=<your platform> production=yes tools=no target=release

Some things to be aware of:

5. Altogether Now

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).
    • These files are called steam_api.dll, steam_api64.dll, libsteam_api.so, or libsteam_api.dylib; no other files are needed.
  • 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 the editor or game fail and crash when testing or running the game outside of the Steam client.

  • NOTE: Some people report putting the Steam API file inside their project folder fixes some issues.
  • 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. You can read more about it in our Linux Caveats doc.

6. Good To Go

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's documentation.

7. Shipping Your Game

When uploading your game to Steam, you must upload your game's executable and Steam API .dll/.so/.dylb (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; however, they won't hurt anything.
