Integración de Party con Lobby mediante el SDK de Multiplayer

PlayFab Lobby y PlayFab Party se usan a menudo de forma conjunta para crear y organizar grupos de jugadores antes de incorporarlos a una sesión en red. En este artículo se describe cómo usar los lobbies como un mecanismo cómodo para compartir descriptores de red de Party mediante la biblioteca de Party de C++ con la biblioteca de Multiplayer de C++.

Crear un lobby con una cadena de descriptor de red serializado

Cree un lobby y establezca el descriptor de red de Party estableciendo el descriptor de red de Party en formato de texto en las propiedades del lobby. Para convertir el descriptor de red de Party en una cadena de caracteres, use PartyManager::SerializeNetworkDescriptor(). Las definiciones siguientes son las propiedades del lobby y las claves y valores usados para buscar.

const char* c_propertyKey_LobbyName{ "LobbyName" };
const char* c_propertyKey_PartyDescriptor{ "PartyDescriptor" };

const char* c_searchKey_LobbyGroup{ "string_key1" };    // For Key to identify lobby group
const char* c_searchValue_LobbyGroup{ "PartySample" };  // Use a identifiable string for search lobby group

// The reason for setting this value is to get the lobby name only from the search results, 
// and in practice, change it appropriately for the your game.
const char* c_searchKey_LobbyName{ "string_key2" };
