Initialize Unity Gaming Services
Before you begin your multiplayer game, you must first initialize Unity Gaming Services for your project.
In the Unity Editor, go to the Project window, then select Assets > Scripts.
Right-click (macOS: Ctrl+click) Scripts.
Select Create > Scripting > MonoBehaviour Script.
Name the script
SessionManager
.Right-click (macOS: Ctrl+click) in the Hierarchy window and select Create Empty.
Enter
SessionManager
as the name.Select this new
SessionManager
GameObject.In its Inspector window, select Add Component.
Select your
SessionManager
script.In the Project window, double-click the
SessionManager
script. The script opens in your preselected IDE.Replace the contents of
SessionManager.cs
with the following code:using UnityEngine; using Unity.Services.Core; using System; using Unity.Services.Authentication; public class SessionManager : MonoBehaviour { async void Start() { try { await UnityServices.InitializeAsync(); await AuthenticationService.Instance.SignInAnonymouslyAsync(); Debug.Log($"Sign in anonymously succeeded! PlayerID: {AuthenticationService.Instance.PlayerId}"); } catch (Exception e) { Debug.LogException(e); } } }
In the above code:
- The line
await UnityServices.InitializeAsync();
initializes Unity Gaming Services SDKs. - The line
await AuthenticationService.Instance.SignInAnonymouslyAsync();
anonymously authenticates the player.
The Authentication SDK supports anonymous authentication and external authentication solutions for supported platforms, including mobile and PC. Refer to Approaches to authentication for more details. Anonymous authentication requires no special configuration, making it easier to use than external authentication and more suitable for prototyping.
As the developer, you must authenticate your players after initializing Multiplayer Services in your code.
