Multiplayer Basics in Godot 4.3+

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, C# follows.

Related skills: See multiplayer-sync for state synchronization and interpolation. See dedicated-server for headless export and server deployment.

1. Multiplayer Architecture

Godot uses a client-server model built on top of MultiplayerAPI. One peer acts as the server; all others are clients. Every peer has a unique integer ID assigned by the network layer:

Peer ID	Role
`1`	The server (always)
`2`+	Connected clients — randomly generated unique IDs, not sequential

Multiplayer authority is the concept of ownership over a node. Only the authoritative peer should read input and drive that node's state. By default the server (peer 1) is the authority for every node. Call set_multiplayer_authority(peer_id) to transfer ownership to a client — on every peer, since the call is local and is not replicated.

Server (peer 1)
    ├── Owns game state by default
    ├── Spawns and validates objects
    └── Routes RPCs
Client (peer 2, 3, …)
    ├── Sends input to server via RPC
    └── Receives state updates from server

2. Setting Up ENetMultiplayerPeer

Both sides use the same three steps: create an ENetMultiplayerPeer, call create_server(port, max_clients) or create_client(address, port), then assign it to multiplayer.multiplayer_peer and connect the MultiplayerAPI signals (peer_connected, peer_disconnected, connected_to_server, connection_failed, plus server_disconnected — see §7). Check the create_* return value — it returns an Error, and a silent ERR_CANT_CREATE (port already in use) otherwise looks exactly like a hang.

The server is always peer ID 1; clients receive randomly generated unique IDs, so never assume they are sequential.

Full server and client implementations with every signal handler, in GDScript and C#: references/enet-setup.md

3. RPCs

@rpc (GDScript) / [Rpc] (C#) marks a method as callable across the network. Choose the mode and transfer settings carefully — they affect both security and performance.

RPC Modes

Mode	Who may call it	Executes on
`"authority"` (default)	Only the authority peer	The peer(s) it is sent to
`"any_peer"`	Any connected peer	The peer(s) it is sent to

Transfer Modes

Mode	Delivery	Order	Use For
`"reliable"`	Guaranteed	In-order	Chat, spawn events, important state
`"unreliable"`	Best-effort	Unordered	High-frequency position updates
`"unreliable_ordered"`	Best-effort	In-order per channel	Smooth movement streams

GDScript

# chat.gd
extends Node2D

# Any peer can call; server validates then broadcasts to all peers.
@rpc("any_peer", "reliable")
func send_chat_message(text: String) -> void:
	if not multiplayer.is_server():
		return
	var sender_id := multiplayer.get_remote_sender_id()
	_broadcast_chat.rpc(sender_id, text)


# Only the authority (server) can call this; runs on every peer.
@rpc("authority", "reliable", "call_local")
func _broadcast_chat(sender_id: int, text: String) -> void:
	print("[%d]: %s" % [sender_id, text])


# Client → server: request to spawn an object.
@rpc("any_peer", "reliable")
func request_spawn(scene_path: String, spawn_position: Vector2) -> void:
	if not multiplayer.is_server():
		return
	# Server validates and performs the actual spawn.
	var scene: PackedScene = load(scene_path)
	if scene == null:
		return
	var instance := scene.instantiate()
	instance.global_position = spawn_position
	get_tree().root.add_child(instance)


# High-frequency sync; unreliable_ordered + a channel keeps this off other RPC traffic.
@rpc("authority", "unreliable_ordered", "call_local", 1)
func sync_position(pos: Vector2) -> void:
	global_position = pos

Sending to specific peers:

# Send to everyone (including self if call_local is set):
send_chat_message.rpc("Hello!")

# Send to one specific peer:
send_chat_message.rpc_id(target_peer_id, "Hello!")

C#

// Chat.cs
using Godot;

public partial class Chat : Node2D
{
    // Any peer can call; executes on the server only.
    [Rpc(MultiplayerApi.RpcMode.AnyPeer, TransferMode = MultiplayerPeer.TransferModeEnum.Reliable)]
    public void SendChatMessage(string text)
    {
        if (!Multiplayer.IsServer()) return;
        int senderId = Multiplayer.GetRemoteSenderId();
        Rpc(MethodName.BroadcastChat, senderId, text);
    }

    // Authority only; runs on every peer including the caller.
    [Rpc(MultiplayerApi.RpcMode.Authority,
         CallLocal = true,
         TransferMode = MultiplayerPeer.TransferModeEnum.Reliable)]
    private void BroadcastChat(int senderId, string text)
        => GD.Print($"[{senderId}]: {text}");

    // Client → server: request a spawn.
    [Rpc(MultiplayerApi.RpcMode.AnyPeer, TransferMode = MultiplayerPeer.TransferModeEnum.Reliable)]
    public void RequestSpawn(string scenePath, Vector2 spawnPosition)
    {
        if (!Multiplayer.IsServer()) return;
        var scene = GD.Load<PackedScene>(scenePath);
        if (scene == null) return;
        var instance = scene.Instantiate<Node2D>();
        instance.GlobalPosition = spawnPosition;
        GetTree().Root.AddChild(instance);
    }

    // High-frequency position sync.
    [Rpc(MultiplayerApi.RpcMode.Authority,
         CallLocal = true,
         TransferMode = MultiplayerPeer.TransferModeEnum.UnreliableOrdered,
         TransferChannel = 1)]
    public void SyncPosition(Vector2 pos)
        => GlobalPosition = pos;
}

Sending to specific peers in C#:

// Broadcast to all:
Rpc(MethodName.SendChatMessage, "Hello!");

// Send to one peer:
RpcId(targetPeerId, MethodName.SendChatMessage, "Hello!");

4. Authority Model

Every node has exactly one authoritative peer — the peer that is permitted to send state updates for that node. Other peers should treat incoming state as read-only.

GDScript

# player.gd
extends CharacterBody2D

func _ready() -> void:
	# multiplayer.get_unique_id() = this peer's ID; server assigns authority during spawn (see Section 6).
	pass


func _physics_process(delta: float) -> void:
	# Guard: authority-only input and movement.
	if not is_multiplayer_authority():
		return

	var direction := Input.get_vector("ui_left", "ui_right", "ui_up", "ui_down")
	velocity = direction * 200.0
	move_and_slide()

	sync_position.rpc(global_position)


@rpc("authority", "unreliable_ordered", "call_local", 1)
func sync_position(pos: Vector2) -> void:
	if not is_multiplayer_authority():
		global_position = pos


func print_authority_info() -> void:
	print("My peer ID : %d" % multiplayer.get_unique_id())
	print("Authority  : %d" % get_multiplayer_authority())
	print("Am I auth? : %s" % str(is_multiplayer_authority()))

C#

// Player.cs
using Godot;

public partial class Player : CharacterBody2D
{
    public override void _PhysicsProcess(double delta)
    {
        // Guard: authority-only input.
        if (!IsMultiplayerAuthority()) return;

        var direction = Input.GetVector("ui_left", "ui_right", "ui_up", "ui_down");
        Velocity = direction * 200f;
        MoveAndSlide();

        Rpc(MethodName.SyncPosition, GlobalPosition);
    }

    [Rpc(MultiplayerApi.RpcMode.Authority,
         CallLocal = true,
         TransferMode = MultiplayerPeer.TransferModeEnum.UnreliableOrdered,
         TransferChannel = 1)]
    private void SyncPosition(Vector2 pos)
    {
        if (!IsMultiplayerAuthority())
            GlobalPosition = pos;
    }
}

API summary:

Method	Returns	Notes
`multiplayer.get_unique_id()`	`int`	This peer's ID
`get_multiplayer_authority()`	`int`	ID of the peer that owns this node
`is_multiplayer_authority()`	`bool`	True if this peer owns this node
`set_multiplayer_authority(id)`	`void`	Transfer ownership; local only — call it on every peer (e.g. in the spawn function)

5. Spawning Networked Objects

Use MultiplayerSpawner to replicate scene instances across peers. Register the scenes (add_spawnable_scene() or the inspector's Auto Spawn List); when the server adds an instance of one as a direct child of the spawn_path node, the spawner instantiates it on every peer. For a spawn that needs data (position, owner), set spawn_function and call spawn(data) on the server.

See references/spawning-networked-objects.md for MultiplayerSpawner scene setup and the spawn-on-server flow (GDScript + C#).

6. Player Join Flow

The full lobby-join lifecycle: peer connects → server allocates a slot → load lobby scene → spawn player node → broadcast peer-list to all clients → on "start match" RPC, transition all peers to gameplay scene.

See references/player-join-flow.md for the full GDScript and C# implementation (peer-connected handler, slot allocation, lobby state, gameplay transition).

7. Disconnect Handling

Listen for peer_disconnected(id) on the multiplayer API. On the server: free the disconnected peer's player node and broadcast the updated peer-list. On clients: detect a server-disconnect and route to a reconnect / main-menu screen.

See references/disconnect-handling.md for the timeout detection settings, server-side cleanup, and client-side reconnect flow (GDScript + C#).

8. Common Pitfalls

Pitfall	Symptom	Fix
Calling an RPC on the wrong authority	Method never runs; the receiver logs `RPC '…' is not allowed on node …`	Check `is_multiplayer_authority()` before sending; use `"any_peer"` only where intentional
Desync from unordered RPCs	Positions jitter or snap	Use `"unreliable_ordered"` for streams; use `"reliable"` for critical state changes
Reading input in `_process` vs `_physics_process`	Movement desyncs on different frame rates	Always move `CharacterBody2D` in `_physics_process`; send sync RPCs from there too
Not checking `is_multiplayer_authority()` before input	Every peer controls every player	Add an `if not is_multiplayer_authority(): return` guard at the top of input handling
Spawning without `MultiplayerSpawner`	Object appears on server, missing on clients	Add replicated instances under a `MultiplayerSpawner`'s `spawn_path` (scene in its spawnable list), or use its `spawn()` with a `spawn_function`
Forgetting `call_local` on authority RPCs	Server state diverges from its own node	Add `"call_local"` when the sender also needs to execute the RPC locally
Calling `rpc()` before the client has connected	Error `Trying to call an RPC via a multiplayer peer which is not connected.`	On clients, send RPCs only after `connected_to_server` (before a peer is assigned, the default `OfflineMultiplayerPeer` runs only `call_local` RPCs, and only locally)
Not stripping `res://` scenes from exported builds	Clients can read server-only scripts	Leave server-only files out of the client preset (Resources tab: export mode or exclude filters), or use PCK encryption for sensitive server code

9. Checklist

ENetMultiplayerPeer.create_server() / create_client() return OK before assigning to multiplayer.multiplayer_peer
All five multiplayer signals connected: peer_connected, peer_disconnected, connected_to_server, connection_failed, server_disconnected
Every node that reads player input guards with `if not is_multiplayer_a

# Multiplayer Basics in Godot 4.3+

All examples target Godot 4.3+ with no deprecated APIs. GDScript is shown first, C# follows.

**Related skills:** See **multiplayer-sync** for state synchronization and interpolation. See **dedicated-server** for headless export and server deployment.

---

## 1. Multiplayer Architecture

Godot uses a **client-server model** built on top of `MultiplayerAPI`. One peer acts as the server; all others are clients. Every peer has a unique integer ID assigned by the network layer:

| Peer ID | Role |
|---------|------|
| `1` | The server (always) |
| `2`+ | Connected clients — randomly generated unique IDs, **not** sequential |

**Multiplayer authority** is the concept of ownership over a node. Only the authoritative peer should read input and drive that node's state. By default the server (peer `1`) is the authority for every node. Call `set_multiplayer_authority(peer_id)` to transfer ownership to a client — on **every** peer, since the call is local and is not replicated.

```
Server (peer 1)
    ├── Owns game state by default
    ├── Spawns and validates objects
    └── Routes RPCs
Client (peer 2, 3, …)
    ├── Sends input to server via RPC
    └── Receives state updates from server
```

---

## 2. Setting Up ENetMultiplayerPeer

Both sides use the same three steps: create an `ENetMultiplayerPeer`, call `create_server(port, max_clients)` or `create_client(address, port)`, then assign it to `multiplayer.multiplayer_peer` and connect the `MultiplayerAPI` signals (`peer_connected`, `peer_disconnected`, `connected_to_server`, `connection_failed`, plus `server_disconnected` — see §7). **Check the `create_*` return value** — it returns an `Error`, and a silent `ERR_CANT_CREATE` (port already in use) otherwise looks exactly like a hang.

The server is always peer ID `1`; clients receive randomly generated unique IDs, so never assume they are sequential.

## 3. RPCs

`@rpc` (GDScript) / `[Rpc]` (C#) marks a method as callable across the network. Choose the mode and transfer settings carefully — they affect both security and performance.

### RPC Modes

| Mode | Who may call it | Executes on |
|------|-----------------|-------------|
| `"authority"` (default) | Only the authority peer | The peer(s) it is sent to |
| `"any_peer"` | Any connected peer | The peer(s) it is sent to |

### Transfer Modes

| Mode | Delivery | Order | Use For |
|------|----------|-------|---------|
| `"reliable"` | Guaranteed | In-order | Chat, spawn events, important state |
| `"unreliable"` | Best-effort | Unordered | High-frequency position updates |
| `"unreliable_ordered"` | Best-effort | In-order per channel | Smooth movement streams |

### GDScript

```gdscript
# chat.gd
extends Node2D

# Any peer can call; server validates then broadcasts to all peers.
@rpc("any_peer", "reliable")
func send_chat_message(text: String) -> void:
	if not multiplayer.is_server():
		return
	var sender_id := multiplayer.get_remote_sender_id()
	_broadcast_chat.rpc(sender_id, text)


# Only the authority (server) can call this; runs on every peer.
@rpc("authority", "reliable", "call_local")
func _broadcast_chat(sender_id: int, text: String) -> void:
	print("[%d]: %s" % [sender_id, text])


# Client → server: request to spawn an object.
@rpc("any_peer", "reliable")
func request_spawn(scene_path: String, spawn_position: Vector2) -> void:
	if not multiplayer.is_server():
		return
	# Server validates and performs the actual spawn.
	var scene: PackedScene = load(scene_path)
	if scene == null:
		return
	var instance := scene.instantiate()
	instance.global_position = spawn_position
	get_tree().root.add_child(instance)


# High-frequency sync; unreliable_ordered + a channel keeps this off other RPC traffic.
@rpc("authority", "unreliable_ordered", "call_local", 1)
func sync_position(pos: Vector2) -> void:
	global_position = pos
```

**Sending to specific peers:**

```gdscript
# Send to everyone (including self if call_local is set):
send_chat_message.rpc("Hello!")

# Send to one specific peer:
send_chat_message.rpc_id(target_peer_id, "Hello!")
```

### C#

```csharp

    {
        if (!Multiplayer.IsServer()) return;
        int senderId = Multiplayer.GetRemoteSenderId();
        Rpc(MethodName.BroadcastChat, senderId, text);
    }

    // Authority only; runs on every peer including the caller.
    [Rpc(MultiplayerApi.RpcMode.Authority,
         CallLocal = true,
         TransferMode = MultiplayerPeer.TransferModeEnum.Reliable)]
    private void BroadcastChat(int senderId, string text)
        => GD.Print($"[{senderId}]: {text}");

    // Client → server: request a spawn.

        var scene = GD.Load<PackedScene>(scenePath);
        if (scene == null) return;
        var instance = scene.Instantiate<Node2D>();
        instance.GlobalPosition = spawnPosition;
        GetTree().Root.AddChild(instance);
    }

    // High-frequency position sync.
    [Rpc(MultiplayerApi.RpcMode.Authority,
         CallLocal = true,
         TransferMode = MultiplayerPeer.TransferModeEnum.UnreliableOrdered,
         TransferChannel = 1)]
    public void SyncPosition(Vector2 pos)
        => GlobalPosition = pos;
}
```

**Sending to specific peers in C#:**

```csharp
// Broadcast to all:
Rpc(MethodName.SendChatMessage, "Hello!");

// Send to one peer:
RpcId(targetPeerId, MethodName.SendChatMessage, "Hello!");
```

Start with one small task

1Read the source. Confirm the input, expected output, dependencies and permissions.
2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.

Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
