Callback Interfaces

Note

These are pure-virtual C++ interfaces that you implement in Lua by providing a table of callback functions to the constructor.

Example — browsing LAN servers with MatchmakingServers.RequestLANServerList():

local response_iface = Steam.newISteamMatchmakingServerListResponse {
    ServerResponded = function(hRequest, iServer)
        local info = Steam.MatchmakingServers.GetServerDetails(hRequest, iServer)
        print('Found server:', info.m_szServerName, info.m_nPlayers .. '/' .. info.m_nMaxPlayers)
    end,
    ServerFailedToRespond = function(hRequest, iServer) end,
    RefreshComplete = function(hRequest, response)
        print('Server list refresh complete, response:', response)
    end,
)
local hRequest = Steam.MatchmakingServers.RequestLANServerList(Steam.Utils.GetAppID(), response_iface)
