The Steamworks C# implementations I found that were compatible with Unity have worked for a long time. But I hate them all. For a number of different reasons.
- They're not C#, they're just a collection of functions.
- They're not up to date.
- They require a 3rd party native dll.
- They can't be compiled into a standalone dll (in Unity).
- They're not free
- They have a restrictive license.
C# is meant to make things easier. So lets try to wrap it up in a way that makes it all easier.
SteamClient.SteamId // Your SteamId
SteamClient.Name // Your Nameforeach ( var friend in SteamFriends.GetFriends() )
{
Console.WriteLine( "{friend.Id}: {friend.Name}" );
Console.WriteLine( "{friend.IsOnline} / {friend.SteamLevel}" );
friend.SendMessage( "Hello Friend" );
}But what if you want to get a list of friends playing the same game that we're playing?
foreach ( var friend in client.Friends.All.Where( x => x.IsPlayingThisGame ) )
{
//
}Console.WriteLine( SteamApps.GameLanguage ); // Print the current game language
var installDir = SteamApps.AppInstallDir( 4000 ); // Get the path to the Garry's Mod install folder
var fileinfo = await SteamApps.GetFileDetailsAsync( "hl2.exe" ); // async get file details
DoSomething( fileinfo.SizeInBytes, fileinfo.Sha1 );var image = await SteamFriends.GetLargeAvatarAsync( steamid );
if ( !image.HasValue ) return DefaultImage;
return MakeTextureFromRGBA( image.Data, image.Width, image.Height );using ( var list = new ServerList.Internet() )
{
list.AddFilter( "map", "de_dust" );
await list.RunQueryAsync();
foreach ( var server in list.Responsive )
{
Console.WriteLine( $"{server.Address} {server.Name}" );
}
}List them
foreach ( var a in SteamUserStats.Achievements )
{
Console.WriteLine( $"{a.Name} ({a.State}})" );
} Unlock them
var ach = new Achievement( "GM_PLAYED_WITH_GARRY" );
ach.Trigger();SteamUser.VoiceRecord = KeyDown( "V" );
if ( SteamUser.HasVoiceData )
{
var bytesrwritten = SteamUser.ReadVoiceData( stream );
// Send Stream Data To Server or Something
}// Client sends ticket data to server somehow
var ticket = SteamUser.GetAuthSessionTicket();
// server listens to event
SteamServer.OnValidateAuthTicketResponse += ( steamid, ownerid, rsponse ) =>
{
if ( rsponse == AuthResponse.OK )
TellUserTheyCanBeOnServer( steamid );
else
KickUser( steamid );
};
// server gets ticket data from client, calls this function.. which either returns
// false straight away, or will issue a TicketResponse.
if ( !SteamServer.BeginAuthSession( ticketData, clientSteamId ) )
{
KickUser( clientSteamId );
}
//
// Client is leaving, cancels their ticket OnValidateAuth is called on the server again
// this time with AuthResponse.AuthTicketCanceled
//

using Steamworks;
// ...
try
{
SteamClient.Init( 4000 );
}
catch ( System.Exception e )
{
// Couldn't init for some reason (steam is closed etc)
}Replace 4000 with the appid of your game. You shouldn't call any Steam functions before you initialize.
When you're done, when you're closing your game, just shutdown.
SteamClient.Shutdown();To create a server do this.
var serverInit = new SteamServerInit( "gmod", "Garry Mode" )
{
GamePort = 28015,
Secure = true,
QueryPort = 28016
};
try
{
Steamworks.SteamServer.Init( 4000, serverInit );
}
catch ( System.Exception )
{
// Couldn't init for some reason (dll errors, blocked ports)
