Facebook extension for Android, iOS, and HTML5.
Updated to cover all current FB functionality as of April 2019 - please note that Facebook have removed several bits of functionality present in older SDKs, so if you were using functions which the code editor now says are no longer in this extension, those things are gone from the SDK (it's not that we're missing them from our extension). Please see the PDF in the extension for more info.
This extension requires an app listing to have already been set up on the Facebook dev site, as you need to put the ID for your app into Game Options -> Android/iOS/HTML5 -> Social.
The manual is in the project included files. Please read the manual as the set-up process has changed.
