将 Amazon GameLift 集成到 Unity 项目中

本主题可帮助您在 Unity 游戏服务器项目中设置 C# 服务器开发工具包。如果您不确定托管 Amazon GameLift 服务是否支持您所使用的操作系统，请参阅适用于游戏服务器。

设置适用于 Unity 的 Amazon GameLift 插件后，您可以在 GitHub 上试用 Amazon GameLifthttps://github.com/aws-samples/amazon-gamelift-unity Unity 示例。

设置适用于 Unity 的 C# Server 开发工具包

执行以下步骤以构建适用于 C# 的 Server 开发工具包并将其添加到您的 Unity 游戏服务器项目。

添加 Amazon GameLift 服务器代码

以下代码示例使用 MonoBehavior，演示使用 Amazon GameLift 执行的简单游戏服务器初始化。

using UnityEngine;
using Aws.GameLift.Server;
using System.Collections.Generic;

public class GameLiftServerExampleBehavior : MonoBehaviour
{
    //This is an example of a simple integration with GameLift server SDK that makes game server 
    //processes go active on Amazon GameLift
    public void Start()
    {
        //Set the port that your game service is listening on for incoming player connections (hard-coded here for simplicity)
        var listeningPort = 7777;

        //InitSDK establishes a local connection with the Amazon GameLift agent to enable 
        //further communication.
        var initSDKOutcome = GameLiftServerAPI.InitSDK();
        if (initSDKOutcome.Success)
        {
            ProcessParameters processParameters = new ProcessParameters(
                (gameSession) => {
                    //Respond to new game session activation request. GameLift sends activation request 
                    //to the game server along with a game session object containing game properties 
                    //and other settings. Once the game server is ready to receive player connections, 
                    //invoke GameLiftServerAPI.ActivateGameSession()
                    GameLiftServerAPI.ActivateGameSession();
                },
                () => {

                    //an instance hosting this game server. It gives this game server a chance to save
                    //its state, communicate with services, etc., before being shut down. 
                    //In this case, we simply tell GameLift we are indeed going to shut down.
                    GameLiftServerAPI.ProcessEnding();

                    //GameLift invokes this callback every 60 seconds or so.
                    //Here, a game server might want to check the health of dependencies and such.
                    //Simply return true if healthy, false otherwise.
                    //The game server has 60 seconds to respond with its health status. 
                    //GameLift will default to 'false' if the game server doesn't respond in time.
                    //In this case, we're always healthy!
