User to User Messaging

Real time user to user messaging is not available via Facebook Instant Games (IG) so this is a none standard functionality. However, that said, it is possible to utilise real-time user to user messaging with IG by working directly with the Xtralife login system to log the user in anonymously then use the user to user messaging system that Xtralife provides to send messages around.

Sending a Message to a User

You can send an event (a message) to another user as follows:

if (FBInstant.ext !== undefined)
{
    var msg = { message : "Here is a gift to you!", currency : 10 };
    FBInstant.ext.sendEventAsync(user_id, msg).then(function(error, data) 
    {
        if (error === null)
            // Message sent
    });
}

Retrieving Messages

To retrieve any pending messages:

if (FBInstant.ext !== undefined)
{
    FBInstant.ext.getEventsAsync().then(function(events) 
    {
        // events contains array of received messages
    });
}
