High Level Multiplayer API.
|
|
</brief_description>
|
|
<description>
|
|
This class implements most of the logic behind the high level multiplayer API.
|
|
By default, [SceneTree] has a reference to this class that is used to provide multiplayer capabilities (i.e. RPC/RSET) across the whole scene.
|
|
It is possible to override the MultiplayerAPI instance used by specific Nodes by setting the [member Node.custom_multiplayer] property, effectively allowing to run both client and server in the same scene.

<method name="get_rpc_sender_id" qualifiers="const">

|
|
<description>
|
|
Returns the sender's peer ID for the RPC currently being executed.
|
|
NOTE: If not inside an RPC this method will return 0.

<method name="has_network_peer" qualifiers="const">
|
|
<return type="bool">
|

</return>
|

<description>
|

Returns [code]true[/code] if there is a [member network_peer] set.

</method>
|
|
<method name="is_network_server" qualifiers="const">
|
|
<return type="bool">
|
|
</return>
|
|
<description>
|
|
Returns [code]true[/code] if this MultiplayerAPI's [member network_peer] is in server mode (listening for connections).
|
|
</description>
|
|
</method>
|
|
<method name="poll">
|
|
<return type="void">
|
|
</return>
|
|
<description>
|
|
Method used for polling the MultiplayerAPI. You only need to worry about this if you are using [member Node.custom_multiplayer] override or you set [member SceneTree.multiplayer_poll] to [code]false[/code]. By default [SceneTree] will poll its MultiplayerAPI for you.
|
|
NOTE: This method results in RPCs and RSETs being called, so they will be executed in the same context of this function (e.g. [code]_process[/code], [code]physics[/code], [Thread]).

|
|
<description>
|
|
Sends the given raw [code]bytes[/code] to a specific peer identified by [code]id[/code] (see [method NetworkedMultiplayerPeer.set_target_peer]). Default ID is [code]0[/code], i.e. broadcast to all peers.

<argument index="0" name="node" type="Node">
|
|
</argument>
|
|
<description>
|
|
Sets the base root node to use for RPCs. Instead of an absolute path, a relative path will be used to find the node upon which the RPC should be executed.
|
|
This effectively allows to have different branches of the scene tree to be managed by different MultiplayerAPI, allowing for example to run both client and server in the same scene.

<member name="allow_object_decoding" type="bool" setter="set_allow_object_decoding" getter="is_object_decoding_allowed">
|
|
If [code]true[/code] (or if the [member network_peer] [member PacketPeer.allow_object_decoding] the MultiplayerAPI will allow encoding and decoding of object during RPCs/RSETs.
|
|
[b]WARNING:[/b] Deserialized object can contain code which gets executed. Do not use this option if the serialized object comes from untrusted sources to avoid potential security threats (remote code execution).

<member name="network_peer" type="NetworkedMultiplayerPeer" setter="set_network_peer" getter="get_network_peer">
|
|
The peer object to handle the RPC system (effectively enabling networking when set). Depending on the peer itself, the MultiplayerAPI will become a network server (check with [method is_network_server]) and will set root node's network mode to master (see NETWORK_MODE_* constants in [Node]), or it will become a regular peer with root node set to puppet. All child nodes are set to inherit the network mode by default. Handling of networking-related events (connection, disconnection, new clients) is done by connecting to MultiplayerAPI's signals.

<member name="refuse_new_network_connections" type="bool" setter="set_refuse_new_network_connections" getter="is_refusing_new_network_connections">

|
If [code]true[/code], the MultiplayerAPI's [member network_peer] refuses new incoming connections.
