    Hi folks,

    If you're after Steam integration with NW.js good news: I've got Greenworks working within a C2 plugin. Here are the downloads (these require C2 r185+, newer NW.js versions require r217+):

    Greenworks plugin releases

    Greenworks 0.3 alpha - for node-webkit 0.10.x


    Greenworks 0.4 - for node-webkit 0.11.x

    Changes in this update:

    • [ADD] 'Is overlay enabled' condition, 'Activate overlay' action
    • [CHANGE] Updated to Greenworks-0.4.0 with support for node-webkit 0.11.x; now supports 64-bit OSX and Windows builds
    • [CHANGE] New icon
    • [FIX] Made 'On achievement success/error' triggers - they previously were not marked as such so probably did not work

    Support notes

    Note if Steam is unavailable or something has gone wrong "is available" will be false, so check it's true before using Steam features. There should be a message in the dev tools console if something went wrong (use the 'Show dev tools' action in the NW.js plugin to check).

    Greenworks also doesn't work in preview mode yet, sorry!

    Changes after export to get Greenworks working

    To get it working you need to make some changes after exporting as NW.js. Note Greenworks does not currently work in preview mode ("is available" will be false).

    1a. Add the Steamworks SDK library to package.nw

    Package.nw is just a zip file with a different extension. You can open it either by renaming it to .zip, adding a file, then renaming it back to .nw (Windows must be set to show file extensions). Alternatively you can associate the .nw file extension with a program that can open zips like WinRAR and just drag-and-drop extra files in.

    Download the Steamworks SDK from the Steam partner site. From the redistributable_bin folder, copy the appropriate file for the platform. For example add steam_api.dll to package.nw for the win32 build, steam_api64.dll for the win64 build, etc.

    Note you must match the Steamworks SDK version listed with the Greenworks version! You may have to download an old version of the Steamworks SDK to make sure it's compatible.

    1b. Add sdkencryptedappticket library

    As of Greenworks for NW.js 0.19.4, you need to add another library file. This can be found in public\steam\lib in the Steamworks SDK. You need to copy this to package.nw in the same way you did for steam_api.dll. For example for the win64 version, copy public\steam\lib\win64\sdkencryptedappticket64.dll to package.nw.

    2. Make sure the executable filename is nw.exe

    For some reason it doesn't work if the executable file has a different name. So make sure the main executable filename is exactly nw.exe. You can always use a shortcut to hide the real name of the executable.

    3. Create a text file named steam_appid.txt in the same folder as nw.exe

    The steam_appid.txt file should contain nothing but your app ID on Steam. If you don't have one yet, for testing you can use Construct 2's app ID of 227240. You must also have Construct 2 installed on your copy of Steam. It can be the free edition, and it works fine side-by-side with a non-Steam install. (If the app ID is not valid and installed, Greenworks won't work.) Also make sure the file has an ANSI/ASCII encoding in your text editor, otherwise it may put a UTF-8 BOM at the start of the file.

    4. Make sure Steam is running and you are logged in to Steam

    Greenworks requires Steam to be running in the background with a logged in user to work.

    5. Start the app and check Greenworks features work.

    Remember: you must match all the versions of Greenworks, NW.js, and the Steamworks SDK. If anything goes wrong use the 'Show dev tools' action to check the browser console.

    Ohhhh shiny!

    Wow, nice! I was considering posting a game up on Greenlight and knew that having Steam features would go a long way towards getting approved, so thanks for this tool.

    Thank you again

    Working great from Windows as well! Amazing work!!!

    Superb news!

    4. Make sure the EXE file is called nw.exe. For some reason it doesn't work if the executable file has a different name.

    Renaming nw.exe is known issue when using native modules;
