AsyncScene - Asynchronous Scene Loader

This Godot tool simplifies loading scenes asynchronously, improving game loading times and enhancing the user experience.

Features

• Background Loading: Load scenes without freezing the main thread, keeping your game responsive.
• Flexible Loading Options: Replace the current scene, add the loaded scene additively, or control loading behavior using different operation types.
• Control over Scene Changes: Choose to switch scenes immediately after loading or manually initiate the scene change.
• Progress Tracking: Monitor the loading progress with a percentage value to provide feedback to the player.
• Load Completion Notifications: Receive signals when scene loading is complete, successful, or failed, allowing for flexible handling.

Usage

1. Initializing the AsyncScene:

extends Node2D

var scene : AsyncScene

func _ready() -> void:
	# Replace the current scene immediately after loading:
	scene = AsyncScene.new("res://path/to/your/scene.tscn", AsyncScene.LoadingSceneOperation.ReplaceImmediate)

	# Replace the current scene manually after loading (call scene.ChangeScene() later):
	# scene = AsyncScene.new("res://path/to/your/scene.tscn", AsyncScene.LoadingSceneOperation.Replace) 

	# Add the loaded scene to the current scene tree:
	# scene = AsyncScene.new("res://path/to/your/scene.tscn", AsyncScene.LoadingSceneOperation.Additive)

	# Add the loaded scene to the current scene tree immediately:
	# scene = AsyncScene.new("res://path/to/your/scene.tscn", AsyncScene.LoadingSceneOperation.AdditiveImmediate)

	# Connect to the OnComplete signal to get notified when loading is finished:
	scene.OnComplete.connect(on_scene_load_complete)

2. Handling Scene Changes (Replace and Additive Operations):

func on_scene_load_complete():
	# If using Replace or Additive operations, call ChangeScene() to finalize the scene change
	scene.ChangeScene()

	# Do something after the scene is loaded, e.g., hide loading screen.
	pass

func _process(delta):
	if scene and scene.isCompleted:
		scene.ChangeScene()

3. Monitoring Loading Progress:

func _process(delta):
	if scene:
		print("Loading progress: ", scene.progress, "%")

4. Unloading the Loaded Scene:

scene.UnloadScene()

5. Checking Loading Status:

var status = scene.GetStatus()  # Returns a string like "THREAD_LOAD_IN_PROGRESS", "THREAD_LOAD_LOADED", etc.

Additional Notes

• This tool can be further customized and extended to fit your specific needs.
• You can incorporate loading bars, progress indicators, or other visual elements to provide a better loading experience for your players.
• Consider using LoadingSceneOperation.ReplaceImmediate for smooth transitions between scenes, while LoadingSceneOperation.Replace allows for more control over when the scene change occurs.
• Remember to call ChangeScene() only if you're using LoadingSceneOperation.Replace or LoadingSceneOperation.Additive for the scene change to take effect.
