SDK Remote Config для Godot Engine (version 1.0.0)

SDK Remote Config is a cloud-based service that lets you change application behaviour and appearance without requiring users to download an application update. The plugin encapsulates configuration request from server, caching, background update. It also offers easy-to-use APIs for data retrieval.

Implementation example

Take a look at example app to learn how to implement SDK Remote Config.

Key features

• Select the most relevant mechanism for updating the configuration.
• Specify the percentage of configuration distribution per audience.
• Pass additional information to build a funnel of a specific configuration. You can even build up configurations for specific users.
• A set of callbacks that can be used for analytics.
• Minimal external dependencies.

Connecting to project

Build the plugin and install it in your project:

1. Copy the plugin project and example application from the official RuStore repository on GitFlic;

2. Open the Android project from the godot_plugin_libraries folder in your IDE.

3. Save the godot_plugin_libraries / libs package to godot-lib.xxx.yyy.template_release.aar folder, where xxx.yyy is the version of your Godot Engine edition.

4. Run gradle assemble to build the project.

   If the build is successful, the following files will be created in godot_example / android / plugins:

   • RuStoreGodotRemoteConfig.gdap;

   • RuStoreGodotRemoteConfig.aar;

   • RuStoreGodotCore.gdap;

   • RuStoreGodotCore.aar.

   caution

   Please note that plugin libraries must be built for your version of Godot Engine.

5. Copy the contents of godot_example / android / plugins to your_project / android / plugins.

6. In the Plugins list tick RuStore Godot Remote Config и RuStore Godot Core plugins in your Android build preset.

Initialization

RemoteConfigClient creation

RuStoreGodotRemoteConfigBuilder initialization must be done during Application.onCreate() as by the background sync start the SDK must be already initialized.

To initialise RemoteConfigClient, extend your Application class and add the following code to onCreate:

import ru.rustore.godot.remoteconfig.model.GodotUpdateBehaviour;
import ru.rustore.godot.remoteconfig.RuStoreGodotRemoteConfigBuilder;

public class GodotRemoteConfigApplication extends Application {
	public final String APP_ID = "a83c91d3-21b4-4891-841e-0ed0fc39a562";
	public final int UPDATE_TIME = 15;
	public final GodotUpdateBehaviour UPDATE_BEHAVIOUR = GodotUpdateBehaviour.Actual;
	
	@Override
	public void onCreate() {
		super.onCreate();
		
		RuStoreGodotRemoteConfigBuilder.INSTANCE.init(APP_ID, UPDATE_BEHAVIOUR, UPDATE_TIME, null, null, getApplicationContext());
	}
}

• APP_ID — remote config unique ID. Available in RuStore Console on the Remote Configuration Parameters Creation page;
• UPDATE_TIME — update timer interval in minutes;
• UPDATE_BEHAVIOUR — parameter that defines SDK behaviour. See Difference in UpdateBehaviour values.

To replace the Application class with GodotRemoteConfigApplication, add the android:name attribute to application in your project's your_project / android / build / AndroidManifest.xml manifest file.

AndroidManifest.xml

<application
	android:name="com.godot.game.GodotRemoteConfigApplication">

UpdateBehaviour

UpdateBehaviour— this parameter defines SDK behavior. The default value of the RemoteConfigClientBuilder instance upon creation is UpdateBehaviour.Defaultwith a 15 minute sync interval.

Differences in the values of UpdateBehaviour

UpdateBehaviour	Description
Actual	With this type of initialization, **every ** configuration request is made by a request to the server. The ** Actualupdate type ensures the configuration is up to date, however, the speed of the configuration retrieval will depend on the network speed.** This type of initialization cancels the background update.
Default	With this type of initialization, the configuration request is made from the local store that is updated at specified intervals. If it is the first initialization (the local store is empty), a request to the server is made. Theduration of this request depends on the network speed. Configuration access will wait for the initialization to complete. The Default configuration does not guarantee that during the process lifetime configuration retrieval will return the same result, as there can be configuration sync in the background. This initialization type starts background update.
Snapshot	With this type of initialization, the configuration request is made from the local inMemory storage. inMemory-storage will receive the result of the request from the permanent store and save it until the end of the process lifetime. If it is the first initialization (the local store is empty), a request to the server is made. Theduration of this request depends on the network speed. Configuration access will wait for the initialization to complete. The Snapshotconfiguration ensures that during the process lifetime configuration retrieval will return the same result. This initialization type starts background update.

Optional initialization parameters

You can set optional initialisation parameters via RemoteConfigParameters interface.

Интерфейс RemoteConfigParameters

package ru.rustore.godot.remoteconfig.model;

public interface RemoteConfigParameters {
    String getAppBuild();
    String getAppVersion();
    String getDeviceId();
    String getDeviceModel();
    String getEnvironment();
    String getOsVersion();
}

The Account and Language parameters are available for dynamic transfer via setAccount and setLanguage methods, respectively: The setAccount and setLanguage methods can be called at any time.

Initialization in GDScript

Before calling the library methods, you must create a push notification client object RuStoreGodotRemoteConfigClient.

Создание клиента

var _remoteConfig_client: RuStoreGodotRemoteConfigClient = null

func _ready():
	_remoteConfig_client = RuStoreGodotRemoteConfigClient.get_instance()

Dynamic parameters

The Account and Language parameters are available for dynamic transfer via setAccount and setLanguage methods, respectively:

_remoteConfig_client.setAccount("Auff")
_remoteConfig_client.setLanguage("ru")

You can get the current parameters via get_account and get_language methods:

var account: String = _remoteConfig_client.get_account()
var language: String = _remoteConfig_client.>get_language()

SDK callbacks

Subscribe to the following events to receive SDK activity callbacks, such as completed initialisation and on-going storage updates.

• rustore_background_job_errors – returns a background operation error.

• rustore_init_complete - called when initialisation is complete.
• rustore_memory_cache_updated - called when memory cache is changed.
• rustore_persistent_storage_updated - called when on-going storage is changed.
• rustore_remote_config_network_request_failure - called when a Remote Config network request fails.

The on_get_remote_config_success callback returns a Dictionary collection with a set of available parameters. The collection contains the entire set of keys and values that were transferred from the server. It depends on the dynamically set parameters as well as the parameters specified upon initialisation.

The on_get_remote_config_failure callback returns a RuStoreError object with error information in the Error parameter. The structure of RuStoreError is described in Error Handling.

Possible errors

It is not recommended to display the error to the user if you get *_failure in response. Showing an error can negatively impact the user experience.
