Hey guys,
I'm trying to design a game (that is played in person) in which you connect multiple devices together via the app. So for example, if everyone had the app open, and one person clicked a button, it would have an output on everyone else's phones. Is this possible, and if so, how?
Read about MQTT.
Yes. Use Firebase or CloudDB realtime databases or possibly a Google Sheet.
The following are not games, but the examples use principles that can be used in a game.
Here is an app that uses a CloudDB to monitor your family herd How to: A Family Chat app built with the MIT CloudDB component
I have made a chase app and a maze game that are multi-player. You probably can do something similar.
Here is a two person game Mountain Kingdom - a chat real time two player, two device game using the CloudDB and a Canvas . It can be adapted for more players.
