Flox is also easily integrated with Google+.
The usual way to go about this is logging in players to their Google+ account and then bind their game data to this account using Flox. Start out by using the code snippet below:
//Fetch the player's Google ID
var id:String = "john-doe-123";
//Hash the ID to ensure player privacy
var hash:String = createUID(16, "google-" + id);
//Authenticate the player with Flox
Player.loginWithKey(hash,
function onComplete(player:Player) {
//Yay! The player is logged in!
},
function onError(message:String) {
//Darn! Something went wrong while authenticating the player.
}
);
