```GDScript
func steam_join_request(lobby_name : String, has_password : bool) -> void:
	if !has_password:
		#Directly join the lobby
		#GDSync.join_lobby(lobby_name)

	GDSync.expose_func(update_health)

func _process(_delta: float) -> void:
	if Input.is_action_just_pressed("heal"):
		# 2. Call the exposed function on all connected clients
		GDSync.call_func_all(update_health, 100)
		
		# Or call it on a specific client using their ID:
		# GDSync.call_func_on(client_id, update_health, 100)

func update_health(amount: int) -> void:
	print("Health updated to: ", amount)
```

--------------------------------

### Set Account Document

Source: https://www.gd-sync.com/docs/cloud-storage

Stores a document at a specified path within the account. Collections are created automatically if they don't exist. Ensure you handle potential response codes for errors like data caps or rate limits.

```gdscript
func _ready():
	var document : Dictionary = {
		"Info" : "This is a document!",
		"Numbers" : [1, 3, 523],
		"Godot" : "Is awesome"
	}
	
	var response_code : int = await GDSync.account_document_set("collection1/collection2/document1", document)
	
	if response_code == ENUMS.ACCOUNT_DOCUMENT_SET_RESPONSE_CODE.SUCCESS:
		print("Document created!")
	else:

	GDSync.host_changed.connect(host_changed)
	
	if GDSync.is_host():
		print("I am the host!")
	else:
		print("I am not the host.")

func host_changed(is_host : bool, new_host_id : int):
	print("Client "+str(new_host_id)+" is the new host")
	if is_host:
		print("I am the new host!")
	else:
		print("I am not new the host.")
```

### Lobby Joining API

Source: https://www.gd-sync.com/docs/lobbies

Allows clients to join existing lobbies. Handles password protection and provides feedback on success or failure.

```APIDOC
## Joining a Lobby

To join a lobby, call `GDSync.lobby_join(name : String, password : String)`.

### Method

`GDSync.lobby_join`

### Parameters

#### Path Parameters

- **name** (String) - Required - The exact name of the lobby to join.
- **password** (String) - Optional - The password for the lobby if it is password-protected.

### Signals Emitted on Join

- **`GDSync.lobby_joined(lobby_name : String)`**: Emitted when the join is successful. `lobby_name` is the name of the lobby entered.
- **`GDSync.lobby_join_failed(lobby_name : String, error : int)`**: Emitted when the join fails. `lobby_name` is the name attempted, and `error` is an integer error code.

### Notes

- The `configuration menu` can enforce unique usernames within a lobby. If enabled, duplicate usernames will prevent a client from joining until a unique name is chosen.
```

--------------------------------

### Synchronize a Variable Across Clients

Source: https://www.gd-sync.com/docs/remote-calls

Expose a variable and then synchronize its updated value to all other clients in the lobby. This script must exist on all clients.

```GDScript
# This Node with this script must exist on all clients in order to work

var test_var : int = 0

func _ready() -> void:
	# Expose the function so it may be synced remotely
	GDSync.expose_var(self, "test_var")
	
	# Edit the variable
	test_var = 10
	
	# Sync the edit to other clients
	GDSync.sync_var(self, "test_var")
	# test_var is now 10 on all clients!
```
