I'm looking for the best way to let the User restore his save file or play on another device.
The documentation says "JSON data to the server with the AJAX object and storing it in a server database".
Well, I have an online server with MySQL Database but no idea how to do this in Construct.
Is there an example or another way to save easily online?
This addon collection will save you tons of trouble. Refer to the PlayFab Master Collection under the Construct Master Collection.
This lets you sync data through Facebook, Google Plus, Android, IOS, Cryptographic ID or your own Company Server (which is managed by PlayFab) easily with the addons.
This supports all platforms available on the Construct 3 Export.
