Lobbies

Adding multiple users in a session works by invoking the lobbies API.

A LobbyId connects multiple user sessions together to display a multiplayer experience.

When multiple sessions have the same LobbyId, it allows our system to logically group these sessions together with minimal client side effort.

An example implementation is as follows:

Request unique LobbyId from Cognitive3D API:

// Unity game server example code:
class LobbyResponse
{
    public string id;
}

IEnumerator GetLobbyId(string APIKey)
{   
    // Post to Lobbies API
    using (UnityWebRequest www = UnityWebRequest.Post("https://data.cognitive3d.com/v0/lobbies",""))
    {
        // Add Project APIKey to header
        www.SetRequestHeader("Authorization", "APIKEY:DATA " + APIKey);
        yield return www.SendWebRequest();

        // Get response
        LobbyResponse lobbyresponse = JsonUtility.FromJson<LobbyResponse>(www.downloadHandler.text);
    }
}

Set LobbyId for each client:

// Game client
CognitiveVR_Manager.SetLobbyId(lobbyid);
