SetNet.Party

Party / group system for SetNet.

A party is a small persistent group of friends who stick together across lobbies and matches. Unlike a room (which is a game session), a party lives before and between games: you invite friends by code, see who's ready, and then enter matchmaking or a room as a group.

This package gives you:

• create / join a party by a short code,
• a leader (the creator; auto-promoted if they leave),
• per-member ready state,
• events for join / leave / leader-changed / ready-changed / disbanded.

Added by composition — no base class, works alongside your regular messages.

Install

dotnet add package SetNet
dotnet add package SetNet.Party

Setup

PartyRuntime.Enable();     // once at startup, both ends, before creating client/server

Server

server.UseParties();       // that's it — parties are node-local, no store needed

Client

var party = client.UseParty();

party.PlayerJoined  += id => Log($"{id} joined");
party.PlayerLeft    += id => Log($"{id} left");
party.LeaderChanged += id => Log($"{id} is now leader");
party.ReadyChanged  += (id, ready) => UpdateReadyIcon(id, ready);
party.Disbanded     += () => ReturnToMainMenu();

// create a party (you become the leader):
var info = await party.CreateAsync();
Share(info.Code);                       // e.g. "K7Q2MZ" — send to friends

// a friend joins:
var joined = await party.JoinAsync("K7Q2MZ");
foreach (var m in joined.Members)
    Log($"{m.PlayerId} ready={m.Ready}");

// ready up / leave:
await party.SetReadyAsync(true);
await party.LeaveAsync();

Entering matchmaking as a group

The leader waits until everyone is ready, then enqueues the whole party into SetNet.Matchmaking with a shared queue key so members land in the same match:

party.ReadyChanged += (_, _) =>
{
    var p = party; // snapshot
    if (IsLeader && p != null && AllReady(p))
        foreach (var member in p.Members)
            /* each client calls */ matchmaking.FindMatchAsync(new MatchRequest { Queue = "ranked" });
};

(Party keeps the group together; Matchmaking places them; Rooms is the resulting session. The three compose.)

API

Client — PartyClient (client.UseParty()):

PartyInfo: Code, OwnPlayerId, LeaderId, IReadOnlyList<PartyMember> Members. PartyMember: PlayerId, Ready.

Server — server.UseParties() installs the handler + auto-removes members on disconnect.

Notes

• Leader promotion: the leader is the first member; if they leave or disconnect, the next member becomes leader and everyone gets LeaderChanged. An empty party is dropped.
• Codes are 6 chars from an unambiguous alphabet (no O/0/I/1), collision-checked.
• Node-local (parties are live peers on one server node), like Rooms. A multi-node deployment would coordinate through a shared store.
• Reserved wire types 65511 / 65512 / 65513. Serializer-agnostic (hand-framed protocol); the player-facing data is fully typed (PartyInfo/PartyMember).
