Spawnable scenes can be configured in the editor or through code (see [method add_spawnable_scene]).
2023-01-05 08:44:01 +01:00
Also supports custom node spawns through [method spawn], calling [member spawn_function] on all peers.
2022-07-29 01:30:30 +02:00
Internally, [MultiplayerSpawner] uses [method MultiplayerAPI.object_configuration_add] to notify spawns passing the spawned node as the [code]object[/code] and itself as the [code]configuration[/code], and [method MultiplayerAPI.object_configuration_remove] to notify despawns in a similar way.

Requests a custom spawn, with [param data] passed to [member spawn_function] on all peers. Returns the locally spawned node instance already inside the scene tree, and added as a child of the node pointed by [member spawn_path].
2022-07-29 01:30:30 +02:00
[b]Note:[/b] Spawnable scenes are spawned automatically. [method spawn] is only needed for custom spawns.

Method called on all peers when for every custom [method spawn] requested by the authority. Will receive the [code]data[/code] parameter, and should return a [Node] that is not in the scene tree.
[b]Note:[/b] The returned node should [b]not[/b] be added to the scene with [method Node.add_child]. This is done automatically.
