The fourth parameter in that call is a listener.
My issue was that you had to have an instance of the listener (RealTimeMultiplayerListener)
I did some digging and found that the RealTimeMultiplayerListener class is an interface so you can’t instantiate it.
That being said you’ll have to write a script to implement that interface.
You will also have to override the methods to do what you want.
Then you should have a working listener.
I’m currently implementing it now. I’ll post some code if you need it when I’m done.
(Also I’m a coder by trade so let me know if you’d like me to talk at a higher level)
You have to inherit your class from GooglePlayGames.BasicApi.Multiplayer.RealTimeMultiplayerListener. Then you add the functionality. You CANNOT attach this class to an object. Make a static and public method called CreateQuickMatch as well. You’ll need to make a reference (instance) of the Listener.
For example:
public class MultiplayerManager : GooglePlayGames.BasicApi.Multiplayer.RealTimeMultiplayerListener
{
private static MultiplayManager sInstance = new MultiplayerManager;
