Godot Multiplayer (4.x high-level)

Connect peers, call functions remotely with @rpc, assign authority, and replicate state with MultiplayerSpawner/MultiplayerSynchronizer. Targets Godot 4.3+ (ENet). Treat all client input as untrusted; keep the server authoritative.

When to use

• Use when adding networked multiplayer: hosting/joining over ENet, calling RPCs, assigning per-node authority, or auto-spawning/syncing nodes across peers.

When not to use: local split-screen (no networking); raw TCP/UDP/WebSocket protocol work (low-level PacketPeer); HTTP requests. For save/persistence → save-systems.
