High Level Epic Online Services

Following are the main classes in High Level Epic Online Services. They also have documentation in the Godot Editor:

HPlatform
HAuth
HAchievements
HFriends
HStats
HLeaderboards
HLobbies
HP2P
HLog

A basic example of using High Level EOS:

# In main script
extends Node

func _ready() -> void:
	# Setup HEOS Logs
	HLog.log_level = HLog.LogLevel.INFO

	var credentials = HCredentials.new()
	credentials.product_name = "PRODUCT_NAME_NAME"
	credentials.product_version = "PRODUCT_VERSION_HERE"
	credentials.product_id = "PRODUCT_ID_HERE"
	credentials.sandbox_id = "SANDBOX_ID_HERE"
	credentials.deployment_id = "DEPLOYMENT_ID_HERE"
	credentials.client_id = "CLIENT_ID_HERE"
	credentials.client_secret = "CLIENT_SECRET_HERE"
	# optional 
	#credentials.encryption_key = "ENCRYPTION_KEY_HERE"
	
	var setup_success := await HPlatform.setup_eos_async(credentials)
	if not setup_success:
	    printerr("Failed to setup EOS. See logs for more details")
	    return

	# Setup Logs from EOS
	HPlatform.log_msg.connect(_on_eos_log_msg)
	var log_res := HPlatform.set_eos_log_level(EOS.Logging.LogCategory.AllCategories, EOS.Logging.LogLevel.Info)
	if not EOS.is_success(log_res):
		printerr("Failed to set logging level")
		return

	HAuth.logged_in.connect(_on_logged_in)

	# During development use the devauth tool to login
	HAuth.login_devtool_async("localhost:4545", "CREDENTIAL_NAME_HERE")

	# Or login without any credentials
	# await HAuth.login_anonymous_async()


func _on_logged_in():
	print("Logged in successfully: product_user_id=%s" % HAuth.product_user_id)

	# Example: Get top records for a leaderboard
	var records := await HLeaderboards.get_leaderboard_records_async("LEADERBOARD_ID_HERE")
	print(records)


func _on_eos_log_msg(msg: EOS.Logging.LogMessage) -> void:
	print("SDK %s | %s" % [msg.category, msg.message])

How does it work

This project uses GDExtension to wrap the Epic Online Services C SDK so that it can be easily used in Godot using GDScript, C#, etc with similar class hierarchy and static type support. It makes use of signals for sending events like user login, logout, achievement unlock, etc.

Installation

This is a regular plugin for Godot 4.2+. To install the plugin follow the steps below:

Method 1: Install from Asset Library

Asset Library link: View the plugin on Godot Asset Library
In the Godot editor, navigate to the AssetLib tab, and in the search bar type EOSG.
Click on the plugin with name Epic Online Services Godot (EOSG) by 3ddelano
In the popup that opens, click the Download button.
Once the download is done, click the Install button.
Goto Project->Project Settings->Plugins and enable the Epic Online Services Godot 4.2+ (EOSG) plugin.
Restart the godot editor.
You can now use the plugin. Head to the Documentation for more information on how to use the plugin.

Method 2: Install from GitHub

Goto the Releases section and download the latest release
Extract the zip file and copy the addons/epic-online-services-godot folder into the res://addons/ folder of your project. If the res://addons does not exist, create it.
In the Godot editor, goto Project->Project Settings->Plugins and enable the Epic Online Services Godot 4.2+ (EOSG) plugin.
Restart the godot editor.
You can now use the plugin. Head to the Documentation for more information on how to use the plugin.

Development Setup

Pre-requisites

Godot Engine 4.2+ (Get it here Godot Engine Download)
Epic Online Services C SDK (Download from Epic Developer Portal)
Make sure you have accepted the Terms and Conditions for Epic Online Services
A product registered with Epic Games Services (Make one for free Epic Developer Portal)

To develop this plugin, follow the below steps:

Download/clone the repository.
Extract the EOS C SDK zip downloaded from Epic Games, rename it to eos-sdk and paste it in the thirdparty/ folder. Refer to the below folder structure.
Build the GDExtension plugin in debug mode (With debug symbols)
```
# In root folder
scons platform=<platform> target=template_debug dev_build=yes
```
Eg. scons platform=windows target=template_debug dev_build=yes

Build the GDExtension plugin for release (Optimized)

# In root folder
scons platform=windows target=template_release

The built GDExtension library will be in the res://addons/epic-online-services-godot/bin/ folder of the sample project.

Debugging GDExtension on MacOS

If you get an error Not allowed to attach to process trying to debug GDExtension on MacOS using LLDB. Run the below command:

codesign --entitlements debug-entitlements.plist -f -s - /Applications/Godot.app/Contents/MacOS/Godot

How to run the sample project?

The sample Godot project is located in the sample folder

Clone/Download the repo.
Download the latest release from the Releases section and replace the existing /addons/epic-online-services-godot with the one from the Release (this includes the built shared libraries).
Copy your credentials (Product Id, Sandbox Id, Deployment Id, Client Id, Client Secret) of your Epic Games "Product" from the Epic Games Dev Portal and paste them in Main.gd script in the relevant sections. The encryption key is a random 64 character long string. These credentials need to be kept as private as possible. One way is to make sure to encrypt all scripts when exporting the final game. ( See Compiling with script key encryption)
Configure your Product on the EOS Dev Portal with the following configuration:

In the Client Policies section in Product Settings, for the Client policy type choose Custom policy, enable the User is required and enable every features and action except Connect (Trusted Server Required). This will allow the sample to access the different services provided by Epic Online Services. In your actual game, the client policy is important and you should give minimal permissions to features.
In the Permissions section of Epic Account Services, enable all three: Basic Profile, Online Presence and Friends.
(Optional if you want some pre-made achievements) In the Achievements section in Game Services, use the Bulk Import option and import the HelloProduct.zip file located at res://HelloProduct.zip

Bootstrapping Godot executable with Epic Online Services

If you want to use the Account Portal login option in Epic Online Services, you need to bootstrap the Godot/Game executable as needed by EOS-SDK 1.15 and greater. See Redistributable Installer

A sample of the generated .ini file for the Godot Editor is shown below (during game development):

ApplicationPath=Godot_v4.2.0-stable_win64.exe
WorkingDirectory=
WaitForExit=0
NoOperation=0

Follow the instructions in Running the service for local development and:

During game development

Bootstrap the Godot Editor executable (eg. Godot_v4.2.0-stable_win64.exe) to test the Account Portal login
After exporting the game

Bootstrap the exported game executable (eg. My Amazing Game.exe)

Exporting for Android

Use a community created Android Export Plugin

Or follow the steps below to manually export for Android.

Pre-requisites

Setup the Android Build Template in your Godot project by following the tutorial Gradle builds for Andriod. This will create an android project in res://android/build.
Now with reference to the tutorial Add the EOS SDK to Your Android Studio Project, perform the following steps.

In the res://android/build/build.gradle file, add the following lines after the implementations in the dependencies section.

Before

dependencies {
    implementation libraries.kotlinStdLib
    implementation libraries.androidxFragment
    ... other code

After

dependencies {
    implementation libraries.kotlinStdLib
    implementation libraries.androidxFragment
    
    // EOS SDK dependencies
    implementation 'androidx.appcompat:appcompat:1.5.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.4'
    implementation 'androidx.security:security-crypto:1.0.0'
    implementation 'androidx.browser:browser:1.4.0'
    implementation 'androidx.webkit:webkit:1.7.0'
    // Update the path so that it points to eossdk-StaticSTDC-release.aar provided in addons/epic-online-services-godot/bin/android/
    implementation files('../../addons/epic-online-services-godot/bin/android/eossdk-StaticSTDC-release.aar')

    ...other code

In the res://android/build/build.gradle file, add the following lines after the defaultConfig in the android section.

Before

android {

    ... other code

    defaultConfig {
        ... other code
    
        // Feel free to modify the application id to your own.
        applicationId getExportPackageName()
        versionCode getExportVersionCode()
        versionName getExportVersionName()
        minSdkVersion getExportMinSdkVersion()
        targetSdkVersion getExportTargetSdkVersion()

        missingDimensionStrategy 'products', 'template'
    }

    ... other code

After

android {

    ... other code

    defaultConfig {
        ... other code
    
        // Feel free to modify the application id to your own.
        applicationId getExportPackageName()
        versionCode getExportVersionCode()
        versionName getExportVersionName()
        minSdkVersion getExportMinSdkVersion()
        targetSdkVersion getExportTargetSdkVersion()

        missingDimensionStrategy 'products', 'template'

        // This is needed by EOS Android SDK
        String ClientId = "PUT YOUR EOS CLIENT ID HERE"
        resValue("string", "eos_login_protocol_scheme", "eos." + ClientId.toLowerCase())
    }

    ... other code

In the res://android/build/config.gradle file, update the minSdk to 23 to match with the requirements of the EOS Android SDK.

Before
```
minSdk             : 21,
```

```
minSdk             : 23,
```

In the res://android/build/src/com/godot/game/GodotGame.java file, update it as follows.

package com.godot.game;

import com.epicgames.mobile.eossdk.EOSSDK;     // added
import org.godotengine.godot.GodotActivity;

import android.os.Bundle;

public class GodotApp extends GodotActivity {
    static {                                   // added
        System.loadLibrary("EOSSDK");          // added
    }                                          // added
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        EOSSDK.init(getActivity());  // added
        
        setTheme(R.style.GodotAppMainTheme);
        super.onCreate(savedInstanceState);

    }
}

Now open your project in the Godot Editor, and goto Project -> Export and create a new Android export profile.
In the Gradle Build section, enable Use Gradle Build. In the Architectures section enable arm64-v8a.
