State, Not Events

25-60 minFree

A current state answers what exists now. An event explains something that happened.

The Spawner

25-60 minFree

Arena contains Players and a MultiplayerSpawner whose spawn_path points to ../Players. Player.tscn is its only allowed scene.

Spawning After Readiness

25-60 minFree

Connection readiness and scene readiness are different. A connected client can still be loading required nodes.

Whose Avatar Is This

25-60 min Guild Hall

Multiplayer authority stays at server ID 1. owner_peer_id identifies whose keyboard may drive this logical player.

The Synchronizer

25-60 min Guild Hall

The local client now sends its claimed position to authority 1. The server checks sender ownership and publishes server_position and facing.

The Cost of a Property

25-60 min Guild Hall

Spawn properties initialize an object. Ongoing properties keep it current after creation.

Late Joiners and Leavers

25-60 min Guild Hall

Net emits peer_leaving before deleting the roster entry. SessionFlow owns ordered world cleanup.

Four in a Room

25-60 min Guild Hall

The Q3 bot uses direct PlayerAvatar bot_driven and bot_move fields. PlayerInput is not introduced until Q4.
