After a few days, I'm still unable to make the achievements work in my game.
Here's my test code
When exported to Steam, the screen displays "SteamOK", then "Error" when I press spacebar (espace).
I'm using NW.JS v0.27 (even though I can't preview the game with it for some reason) and the corresponding Steam4C2-Basic version.
Is there anything else that should be configured in steamworks (except the normal configuration of achievements, as shown below the code) in order to have achievements to work?
Any suggestion of what I'm doing wrong? AJ2DI maybe?
[Edit] I'm using SDK 220.127.116.11 with plugin v. 1.5.1, which seems correct. At the time of posting I was using SDK 1.42, but changing everything to 18.104.22.168 didn't help in any way. I placed all the files from the SDK in the project files as mentionned in the plugin's documentation.
