Whenever I try to create a room with the Google Play Games Services Plug-in for for Unity the progress gets stuck at 20%. 20% is the first and only value that is returned in the OnRoomSetupProgress(float percent) function that is part of my RealTimeMultiplayerListener instance. OnRoomConnected(bool success) never gets called.
Real Time Multiplayer is definitely activated in my Google Play Developer Console (otherwise I'd get error code 6003 - been there). I tested the code on two different devices (Nexus S and Wacom Cintiq Companion Hybrid) on 2 different WLAN networks and 3G. I downloaded the plug-in as a Unity package from the official Git Hub repository. I tested multiple versions (all 0.9.0x packages up to 0.9.07). My Unity version is Unity free 4.5.4 using the free Android extension.
The code itself is based on the Minimal sample that comes with the GPGS Plug-in for Unity. This is the "Behaviour" class that is attached to a game object and is responsible for GUI drawing:
using System.Collections;
using UnityEngine;
using UnityEngine.SocialPlatforms;
using GooglePlayGames;
public class MainGui : MonoBehaviour {
private bool mWaitingForAuth = false;
private bool mWaitingForRoom = false;
private string mStatusText = "Ready.";
private VersusListener vsListener;
void Start() {
PlayGamesPlatform.DebugLogEnabled = true;
PlayGamesPlatform.Activate();
vsListener = new VersusListener();
}
void OnGUI() {
if (mWaitingForRoom) {
mStatusText = "Loading room... " + vsListener.m_roomProgress.ToString() + "%";
}
GUILayout.Label(mStatusText);
if (mWaitingForAuth) {
return;
}
if (mWaitingForRoom) {
if (GUILayout.Button("Cancel")) {
// Cancel room loading!
mStatusText = "Loading room cancelled.";
mWaitingForRoom = false;
PlayGamesPlatform.Instance.RealTime.LeaveRoom();
}
return;
}
if (Social.localUser.authenticated) {
if (GUILayout.Button("Sign Out")) {
// Sign out!
mStatusText = "Signing out.";
((PlayGamesPlatform)Social.Active).SignOut();
}
if (GUILayout.Button("Quick Match")) {
mWaitingForRoom = true;
PlayGamesPlatform.Instance.RealTime.CreateQuickGame(1, 1, 0, vsListener);
}
}
else {
if (GUILayout.Button("Authenticate")) {
// Authenticate
mWaitingForAuth = true;
mStatusText = "Authenticating...";
Social.localUser.Authenticate((bool success) => {
mWaitingForAuth = false;
mStatusText = success ? "Successfully authenticated" : "Authentication failed.";
});
}
}
}
}
...and that's the RealTimeMultiplayerListener interface implementation I use:
using UnityEngine;
using GooglePlayGames.BasicApi.Multiplayer;
public class VersusListener : RealTimeMultiplayerListener {
public bool m_roomLoaded = false;
public bool m_peerConnected = false;
public float m_roomProgress = 0.0f;
public bool m_messageReceived = false;
public string m_message = "";
public void OnRoomSetupProgress(float percent) {
m_roomProgress = percent;
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
Debug.Log(" Room Progress update: " + percent.ToString() + "%");
}
public void OnRoomConnected(bool success) {
m_roomLoaded = success;
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
}
public void OnLeftRoom() {
m_roomLoaded = false;
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
}
public void OnPeersConnected(string[] participantIds) {
m_peerConnected = true;
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
}
public void OnPeersDisconnected(string[] participantIds) {
m_peerConnected = false;
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
}
public void OnRealTimeMessageReceived(bool isReliable, string senderId, byte[] data) {
char[] chars = new char[data.Length / sizeof(char)];
System.Buffer.BlockCopy(data, 0, chars, 0, data.Length);
m_message = new string(chars);
Debug.Log("Versus Listener: Callback - " + System.Reflection.MethodBase.GetCurrentMethod().Name + " called");
}
}
Finally this is the (Unity filtered) log I get:

Empirically found out that 20% means "everything is ready, but no one else is connected". So you got stuck at 20% on both testing devices simultaneously? If so, make sure that you're not trying to log in with same google account (been there). If not, make sure that both devices reach this state.
