## World script for the multiplayer scene. Consumes the host/join request set
|
|
## by the main menu, spawns the world's stations/items on whichever machine
|
|
## owns the world (server, or the local player when offline), spawns/despawns
|
|
## a player avatar per connected peer, and returns to the menu if the session
|
|
## ends.
|
|
##
|
|
## The world's actual content (stations, items) is NOT baked into this scene —
|
|
## it's spawned at runtime from Net/world_layout.gd via NetworkManager, so a
|
|
## joining client receives it from the server (MultiplayerSpawner replays
|
|
## existing spawns to late joiners) instead of relying on its own local copy
|
|
## matching.
