The SteamSDK Service Module provides access to the Steam SDK. With this SDK SteamWorks functionality can be used if Steam is running. If Steam is not running creating the service fails.

The service has the unique identifier SteamSDK.

Support for this service is provided in the DragonScript Script Module using the class ServiceSteam. This service implements the following interfaces:

• ServiceUser
• ServiceStats

The BaseGameApp class automatically creates the SteamSDK service instance if the following values are present in the configuration.ptree.xml file:

An example configuration.ptree.xml file looks like his:

<?xml version='1.0' encoding='UTF-8'?>
<parameterTree>
   <boolean path='defaultEnableGI'>true</boolean>
   <boolean path='defaultEnableAuralization'>true</boolean>
 
   <!-- Steam SDK -->
   <string path='steam.appid'>12345678</string>
</parameterTree>

If Steam is not running creating the SteamSDK service fails. This does not fail starting the application. Check first if the SteamSDK service has been created using:

   if BaseGameApp.getApp().getBaseGameServices().getSteam() != null
      // SteamSDK is ready to be used
   end

The SteamSDK service can be manually created either by using the new constructor on the ServiceSteam class using ServiceSteam.InitParameters setup with the initialization data or by calling initSteam() on BaseGameApp. Using initSteam is preferred if manual creation is required.

The service module provides user management support. Supported is only retrieving user information and user resources. The user can not be logged in or out since a Steam user is always logged in as soon as Steam is running.

The service module provides also Authentification Provider support to other modules. The provider has the unique identifier steam. This feature allows other service modules to link accounts to the logged in Steam user. For this to work you have to call getAuthToken() to asynchronously retrieve an authentification token. Once received in the listener this token can be used on other service modules supporting linking with Steam user accounts.

The service module provides achievement and statistics support. Use setStatsAndAchievements() to set the value of individual statistics. Once the requirements are fulfilled server side the respective achievements will be unlocked. You can also use the same function to manually unlock achievements. Use getStatsAndAchievements() to retrieve the current stats and achievements state.
