Getting started

Before using this plugin please follow instructions on Setting Up Google Play Games Services official guide.

Set up

  • Download GodotPlayGamesServices.release.aar and GodotPlayGamesServices.gdap from releases page.
  • Move the plugin configuration file (GodotPlayGamesServices.gdap) and the binary (GodotPlayGamesServices.release.aar) downloaded from the previous step to the Godot project's res://android/plugins directory.
  • Enable plugin by accessing Project -> Export, Plugins section. Follow the image.
  • Go to res://android/build directory. Add below lines to AndroidManifest.xml:
    <meta-data android:name="com.google.android.gms.games.APP_ID"
   	    android:value="@string/app_id" />
   
   	<meta-data android:name="com.google.android.gms.version"
   	   android:value="@integer/google_play_services_version"/>
  • In the same res://android/build directory,(if it is not already created) create res -> values -> Strings.xml. Add below lines to Strings.xml:
<?xml version="1.0" encoding="utf-8"?>
<resources>
    	<string name="app_id">ADD_YOUR_APP_ID</string>
</resources>

Replace ADD_YOUR_APP_ID with the app id that was generated after following instructions on Setting Up Google Play Games Services

Check demo project. In order demo project to work, replace ADD_YOUR_APP_ID with your own app id, and in Main.gd add your ids for achievements and leaderboards.

How to use

First step is plugin initialization

var play_games_services
# Check if plugin was added to the project
if Engine.has_singleton("GodotPlayGamesServices"):
  play_games_services = Engine.get_singleton("GodotPlayGamesServices")
	
  # Initialize plugin by calling init method and passing to it a boolean to enable/disable displaying game pop-ups
  
  var show_popups := true
  var request_email := true
  var request_profile := true
  #The client id must be created in [the google console](https://console.cloud.google.com/apis/credentials), an OAuth 2.0 Client credentials of a Web application type
  var request_token := "Client ID"

  play_games_services.init(show_popups, request_email, request_profile, request_token)

  # For enabling saved games functionality use below initialization instead
  # play_games_services.initWithSavedGames(show_popups, "SavedGamesName", request_email, request_profile, request_token)
  
  # Connect callbacks (Use only those that you need)

  play_games_services.connect("_on_leaderboard_score_submitting_failed", self, "_on_leaderboard_score_submitting_failed") # leaderboard_id: String
  play_games_services.connect("_on_game_saved_success", self, "_on_game_saved_success") # no params
  play_games_services.connect("_on_game_saved_fail", self, "_on_game_saved_fail") # no params
  play_games_services.connect("_on_game_load_success", self, "_on_game_load_success") # data: String
  play_games_services.connect("_on_game_load_fail", self, "_on_game_load_fail") # no params
