스팀 로그인

스팀 로그인

1. Steamworks.NET 에서 최신 버전을 다운로드 후에 Unity Import 합니다.

1. 프로젝트 루트 폴더에 steam_appid.txt 파일을 생성 후에 스팀에서 발급받은 app ID 많을 넣고 저장해 주세요.

Users & Permissions > Manage Group > Create Group > Create Web API KEY 를 생성해 주세요.

Steam APP ID 와 Web API 키를 게임팟 대시보드 > 연동 > 스팀란에 추가해 주세요.

SteamManager 을 씬을 추가하고 해당 씬에 추가해 주세요.

Assets > Scripts > Steamworks.NET > SteamManager.cs를 Hierarchy의 빈 오브젝스를 생성 추가합니다.

게임팟 로그인 추가 방법

스팀 로그인을 완료 후에 스팀 세션 티켓을 signInWithCredential 를 통해 로그인 처리를 해주시면 됩니다.

NBaseSDK.NBase.signInWithToken("steam", memberId, sessionTicket, (user, error) =>
{
    try
    {
        if(error != null)
        { 
            Debug.Log("Login Success - " + user.ToString());
        }
        memberId = user.Id;
        
    }
    catch (Exception ex)
    {
        Debug.Log($"An exception occurred during sign-in: {ex.Message}");
    }
});
