Video on how plugin works

How to install and use plugin

1. Find, download, and install the "Godot Async Loader" plugin in AssetLib

2. Enable the plugin (Project -> Project Settings -> Plugins -> Enable)

3. Add scenes to groups

4. Setup plugin in main scene

const GROUPS := [
	"terrain",
	"building",
	"furniture",
	"plant",
	"item",
	"npc",
	"etc",
]

func _init() -> void:
	SceneAdder._sleep_msec = 100
	SceneAdder.set_groups(GROUPS)

5. Use the plugin to change to a new scene and load it asynchronously

func _on_start_pressed() -> void:
	SceneSwitcher.change_scene("res://examples/World/World.tscn")

How to load child scene async

# Instance scene asynchronously and add to current scene
var target = get_tree().get_current_scene()
var scene_file := "res://examples/Animals/Puma.tscn"
var pos := Vector3(0, 1, 0)
SceneLoader.load_scene_async(target, scene_file, pos, true)

How to load child scene async with callback

# Instance scene asynchronously and send to callback
var target = get_tree().get_current_scene()
var scene_file := "res://examples/Animals/Puma.tscn"
var pos := Vector3(0, 1, 0)
SceneLoader.load_scene_async_with_cb(target, scene_file, pos, true, funcref(self, "on_animal_loaded"), {})

func on_animal_loaded(path : String, instance : Node, pos : Vector3, is_pos_global : bool, data : Dictionary) -> void:
	var target = get_tree().get_current_scene()
	instance.transform.origin = pos
	target.add_child(instance)

How to load child scene sync

# Instance scene synchronously and add to target scene
var scene_file := "res://examples/Animals/Puma.tscn"
var target = get_tree().get_current_scene()
var instance := SceneLoader.load_scene_sync(target, scene_file)
