I am currently getting ready to publish a game through IDwyz@Xbox and the only thing I need to do before doing my final tests and entering certification is to configure achievements (which is not yet available in the Xbox Live plugin). So, I'm thinking it might be faster if I just figure out how to create a custom plugin for integrating the Xbox Achievements API, rather than wait for the official achievements support (which has no ETA yet). But, I do not have a programming background, so trying to read through this Javascript SDK stuff is like a foreign language to me. Plus, the Xbox achievement API signature (https://docs.microsoft.com/en-us/windows/uwp/xbox-live/achievements-2017/simplified-achievements) is in C++, so that just makes it even more confusing for me.
If anyone here has made plugins in the past, I could definitely use some help or some insight on how I might achieve something like this. Thanks.
