Hi Pagr13, I'll make sure to announce here as soon as it is released.
Regarding your inquiry about server-side app updates, with PlayFab, you have a lot of options and all those mentioned are included and can be used as well.
However, the easiest and most common is through
title data a.k.a game data, which is in the context of Construct 3, is like your own 'constant global variable'.
For protection, the title data is read-only a.k.a constant, but you can also write/modify it through the server, if you allow it, using Cloud Script.
Basically, to use this feature, you add the Title Manager object in your project, and get the title data.
To write your title data, you need to go to your PlayFab console, from your studios and titles list, pick the studio and then the title (game) you want to modify, then go to the
Content tab, and it will by default show the title data page, where you can finally begin writing your title data.
The data structure is similar to writing a Construct 3 dictionary, it is a key-value pair, with the user interface being as user friendly as Construct 3's editor. And to get the value from Construct 3, you run 'Get Title Data' with the keys you want retrieved from the server.
If you have studio-wide data in mind, there is also something called
publisher data a.k.a 'studio data', which is shared among all games under a studio (You can have multiple studios). To use this feature, insert the Publisher object, and use it like the User Data and Title Manager addons.
You can also use Cloud Script, if you like writing functions in your server to process and retrieve the data manually. And other cool cloud scripting features.
Although, basically, the
title data through the Title Manager is the easiest and most convenient way.
There is also Mobile Firebase Config, which is specifically made for this feature, but it is a native implementation restricted to Android and iOS.
