I am doing a game with a scoreboard. And i want to add the possibility to users to add a widget on their phones to check the scoreboard and maybe do other simple actions: it is possible? If yes how can i do?
You won’t be able to make the widget itself in the engine, no.
You could host some kind of server (or MQTT/Firebase) and use the Network (or MQTT/Firebase events) To upload their scores to that server.
You would need to develop the widget for the mobile device using their own SDKs external to GDevelop.
You would need to learn the respective SDKs for the mobile OS in question and understand how their widget systems work.
In order to add widgets you need to code yourself in Cordova for iOS and Android Studio for Android devices.
Ok, thanks for evryone
