using UnityEngine;
using GooglePlayGames;
using GooglePlayGames.BasicApi;

public class GooglePlayGameRegistration : MonoBehaviour
{
    void Start()
    {
        // 配置并初始化Google Play游戏服务
        PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().Build();
        PlayGamesPlatform.InitializeInstance(config);
        PlayGamesPlatform.Activate();

        // 进行Google Play游戏登录
        Social.localUser.Authenticate((bool success) =>
        {
            if (success)
            {
                Debug.Log("Google Play游戏登录成功！");
            }
            else
            {
                Debug.Log("Google Play游戏登录失败！");
            }
        });
    }
}
