We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

<brief_description>

|
High-level multiplayer API interface.
|
|
</brief_description>
|
|
<description>
|
|
Base class for high-level multiplayer API implementations. See also [MultiplayerPeer].
|
|
By default, [SceneTree] has a reference to an implementation of this class and uses it to provide multiplayer capabilities (i.e. RPCs) across the whole scene.
|
|
It is possible to override the MultiplayerAPI instance used by specific tree branches by calling the [method SceneTree.set_multiplayer] method, effectively allowing to run both client and server in the same scene.
|
|
It is also possible to extend or replace the default implementation via scripting or native extensions. See [MultiplayerAPIExtension] for details about extensions, [SceneMultiplayer] for the details about the default implementation.

<description>
|
|
Notifies the MultiplayerAPI of a new [param configuration] for the given [param object]. This method is used internally by [SceneTree] to configure the root path for this MultiplayerAPI (passing [code]null[/code] and a valid [NodePath] as [param configuration]). This method can be further used by MultiplayerAPI implementations to provide additional features, refer to specific implementation (e.g. [SceneMultiplayer]) for details on how they use it.
|
|
[b]Note:[/b] This method is mostly relevant when extending or overriding the MultiplayerAPI behavior via [MultiplayerAPIExtension].

Notifies the MultiplayerAPI to remove a [param configuration] for the given [param object]. This method is used internally by [SceneTree] to configure the root path for this MultiplayerAPI (passing [code]null[/code] and an empty [NodePath] as [param configuration]). This method can be further used by MultiplayerAPI implementations to provide additional features, refer to specific implementation (e.g. [SceneMultiplayer]) for details on how they use it.

<method name="poll">
|
|
<return type="int" enum="Error" />
|
|
<description>
|
|
Method used for polling the MultiplayerAPI. You only need to worry about this if you set [member SceneTree.multiplayer_poll] to [code]false[/code]. By default, [SceneTree] will poll its MultiplayerAPI(s) for you.
|
|
[b]Note:[/b] This method results in RPCs being called, so they will be executed in the same context of this function (e.g. [code]_process[/code], [code]physics[/code], [Thread]).

Sends an RPC to the target [param peer]. The given [param method] will be called on the remote [param object] with the provided [param arguments]. The RPC may also be called locally depending on the implementation and RPC configuration. See [method Node.rpc] and [method Node.rpc_config].
|
|
[b]Note:[/b] Prefer using [method Node.rpc], [method Node.rpc_id], or [code]my_method.rpc(peer, arg1, arg2, ...)[/code] (in GDScript), since they are faster. This method is mostly useful in conjunction with [MultiplayerAPIExtension] when augmenting or replacing the multiplayer capabilities.

<member name="multiplayer_peer" type="MultiplayerPeer" setter="set_multiplayer_peer" getter="get_multiplayer_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_server]) and will set root node's network mode to authority, or it will become a regular client peer. 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.

<constants>

|
|
<constant name="RPC_MODE_ANY_PEER" value="1" enum="RPCMode">
|
|

</constant>
|
|
<constant name="RPC_MODE_AUTHORITY" value="2" enum="RPCMode">
