EditorScript in Godot – Complete Guide

Welcome to an exciting exploration of the EditorScript class in Godot 4, where we turn your Godot editor into a playground for custom functionality. As we delve into scripting within the editor, you’ll discover new ways of streamlining your game development workflow and adding powerful tools to your arsenal. This hands-on tutorial promises to be an engaging journey that can prove invaluable to your projects and coding proficiency. Whether you’re a blossoming game creator or an experienced developer, there’s always something new to learn and apply.

What Is EditorScript?

Godot 4 introduces the EditorScript class as part of its comprehensive game development ecosystem. An EditorScript is essentially a piece of code that extends Godot’s editor by allowing you to run custom scripts directly from the editor’s interface. This opens up opportunities for you to perform tasks within the editor that are tailor-made to fit your unique development needs.

What Is It Used For?

The primary use of EditorScript is to enhance the Godot editor with personalized functions or automation scripts. For example, if you often find yourself setting up scenes in a particular way, you can create an EditorScript to do the job with a single button press. This bespoke functionality can not only save time but also enforce consistency across your projects.

Why Should You Learn It?

Learning how to use EditorScript can significantly improve your productivity and efficiency in game development. It allows you to create custom editor tools without delving into the more complex realm of EditorPlugins, offering a simpler way to tailor the Godot editor to your preferences. Plus, it’s an excellent step into more advanced scripting and tool creation.

Creating a Simple EditorScript

We’ll begin with a simple EditorScript that prints a message to the console. It’s the ‘Hello, World!’ of EditorScripts in Godot 4, a great place to start and understand the process.

extends EditorScript

func _run():
    print("Hello, Editor!")

After you’ve written this script, you can run it through the editor’s Script Editor by selecting ‘File’ -> ‘Run’. If everything is set up correctly, you should see “Hello, Editor!” printed in the output console.

Modifying the Scene from an EditorScript

Let’s move a step further by modifying the current scene from an EditorScript. This example changes the position of the node named “Player” to the origin position (0, 0, 0) when the script is run.

extends EditorScript

func _run():
    var player_node = get_scene().find_node("Player", true, false)
    if player_node:
        player_node.position = Vector3.ZERO
        print("Player node position reset to origin")
    else:
        print("Player node not found")

This script illustrates the power of EditorScript by interacting directly with the scene tree and modifying node properties.

Creating Custom Nodes with EditorScript

You can also use EditorScript to automate the creation of nodes. In this example, we’ll add a new Camera node to our scene.

extends EditorScript

func _run():
    var camera_node = Camera.new()
    get_scene().add_child(camera_node)
    camera_node.transform.origin = Vector3(0, 2, -5)  # Positions the camera above and behind the origin
    print("Camera node has been added to the scene")

Running this script will automatically add a Camera node to your scene, showing the potential for creating scene templates and automating setup processes.

Batch Renaming Nodes

Another practical use of EditorScript is batch operations, such as renaming multiple nodes at once. Take a look at this script that renames all nodes with “OldName” to “NewName”.

extends EditorScript

func _run():
    var nodes_to_rename = get_scene().get_nodes_in_group("RenameGroup")
    for node in nodes_to_rename:
        node.name = "NewName"
    print("All nodes in 'RenameGroup' have been renamed to 'NewName'")

This is an immensely useful script when you have a bunch of nodes that need to be renamed — it saves time and reduces the potential for human error.

By now, you should have a solid understanding of how to create and execute simple EditorScripts in Godot 4. These basic examples serve as a foundation for building more complex and tailored scripts to aide your development process. In the following section, we’ll expand on this to include more advanced operations and optimization techniques.

As we delve deeper into advanced use cases for EditorScript, remember that these snippets are designed to illustrate the class’s potential. They should inspire you to think about how you can automate and enhance your own Godot editor environment. Here are more complex and practical script examples to extend your Godot editor toolset.

Automating Scene Setup: Suppose you need a standard lighting setup for every level in your game. You could use an EditorScript to create and configure the lights for you.

extends EditorScript

func _run():
    var directional_light = DirectionalLight.new()
    directional_light.rotation_degrees = Vector3(-45, -30, 0)
    get_scene().add_child(directional_light)
    print("Directional light added and configured")

This script creates a DirectionalLight and sets its rotation to ensure consistency across all your scenes.

Populating a TileMap: For games utilizing tile-based levels, an EditorScript can automate the process of laying out a basic level structure.

extends EditorScript

func _run():
    var tile_map = preload("res://path_to_your_tilemap_scene.tscn").instance()
    get_scene().add_child(tile_map)
    # Assume the tile with ID 1 is the ground tile
    for x in range(10):
        for y in range(10):
            tile_map.set_cell(x, y, 1)  # Fill a 10x10 area with ground tiles
    print("10x10 ground tiles added to TileMap")

This example adds a 10×10 grid of ground tiles to your tilemap, laying the foundation for your level design process.

Mass-Importing Assets: When you have many assets to import, doing it manually becomes tedious. Here’s an EditorScript that bulk-imports textures from a folder:

extends EditorScript

func _run():
    var path_to_textures = "res://textures"
    var dir = Directory.new()
    if dir.open(path_to_textures) == OK:
        dir.list_dir_begin()
        var file_name = dir.get_next()
        while file_name != "":
            if file_name.ends_with(".png") or file_name.ends_with(".jpg"):
                var texture = preload(path_to_textures.plus_file(file_name))
                print("Imported texture: " + file_name)
            file_name = dir.get_next()
        dir.list_dir_end()

This script imports all PNG and JPG files in the specified folder, avoiding the need to import them one by one.

Applying Project-Wide Node Adjustments: Occasionally, you might need to make an adjustment to all nodes of a certain type across your entire project. Here’s how you could scale all Sprite nodes up by 10%:

extends EditorScript

func _run():
    var scenes_to_check = ["res://level1.tscn", "res://level2.tscn", "res://level3.tscn"]
    for scene_path in scenes_to_check:
        var scene = load(scene_path).instance()
        var sprites = scene.get_children()
        for sprite in sprites:
            if sprite is Sprite:
                sprite.scale *= 1.1
        # Save the modified scene
        ResourceSaver.save(scene_path, scene)
        print("Scaled all sprites in " + scene_path)

This powerful script iterates over specified scenes, scales each Sprite node, and saves the updated scenes.

Custom Inspector Tools: Finally, let’s look at a script that adds a button to our custom inspector plugin, allowing you to trigger specific functionalities directly from the inspector.

extends EditorScript

func _run():
    var plugin_script = preload("res://path_to_your_editor_plugin.gd").new()
    plugin_script.add_custom_control_to_bottom_panel(Button.new(), "MyButton")
    plugin_script.connect("pressed", self, "_on_MyButton_pressed")

func _on_MyButton_pressed():
    print("Magic button pressed!")

This EditorScript modifies the editor to have a new button that, when pressed, performs a decided action—in this case, simply printing a message.

These examples demonstrate how EditorScript can be a powerful tool for automating repetitive tasks, enforcing consistency, and customizing the Godot editor to suit your particular workflow. As you’ve seen, a fundamental understanding of Godot and GDScript empowers you to take full advantage of these capabilities, potentially transforming the way you work on your game projects.

Expanding on the versatility of the EditorScript, let’s look at some additional script examples. They will demonstrate a range of functionalities that can be harnessed to further enhance your Godot editor experience.

Iterating Over All Nodes in a Scene: You might want to process every node in a scene. Here’s how an EditorScript can be used to print the name and type of each node:

extends EditorScript

func _run():
    var root_node = get_scene()
    _process_node(root_node)

func _process_node(node):
    print("Processing node: " + node.name + " (Type: " + node.get_class() + ")")
    for child in node.get_children():
        _process_node(child)

This recursive function walks through the entire scene tree, displaying useful information for each node.

Validating Scene Setup: Imagine you want to ensure that every NPC in your game has an assigned collision layer. You can write an EditorScript to validate this condition:

extends EditorScript

func _run():
    var npcs = get_scene().get_nodes_in_group("NPCs")
    for npc in npcs:
        if npc.collision_layer == 0:
            print("NPC without collision layer found: " + npc.name)
        else:
            print("NPC " + npc.name + " is set up correctly.")

This script checks each NPC and reports any that are lacking a collision layer setup.

Generating Procedural Content: If your game uses procedural generation for certain assets, EditorScript can help you visualize results instantly in the editor.

extends EditorScript

func _run():
    var procedural_map = ProceduralMap.new()
    procedural_map.generate()
    get_scene().add_child(procedural_map)
    print("Procedural map generated and added to scene")

This simplifies the process of tweaking and previewing procedural generation algorithms directly within the editor.

With the power of EditorScript, you are not just limited to influencing the game’s content but also streamlining your development workflow. Here are a couple more examples to illustrate such capabilities:

Optimizing Images: Reducing game size is crucial, and image optimization plays a key role. The following script optimizes all images in a given directory:

extends EditorScript

func _run():
    var image_optimizer = ImageOptimizer.new()
    image_optimizer.optimize_directory("res://assets/images/")
    print("Image optimization complete")

This example assumes the existence of a custom “ImageOptimizer” class that performs the actual image optimization.

Converting 3D Models: If your game has many 3D assets that need to be converted to a specific format, an EditorScript can do that at the push of a button.

extends EditorScript

func _run():
    var model_converter = ModelConverter.new()
    model_converter.convert_all_models("res://models/", "res://converted_models/")
    print("All models converted")

The script calls upon a hypothetical “ModelConverter” class, which handles the conversion process of 3D models from one format to another.

EditorScript not only offers an extensive range of capabilities for automating tasks and enhancing workflows, but it also helps maintain a high level of precision and consistency across all elements of your project. As developers, we strive to produce high-quality content, and these code samples represent some of the best practices in making the Godot editor work for you.

Remember, as you get familiar with writing your own editor scripts, think creatively about the tasks you perform frequently or find tedious. Those are ripe for automation with EditorScript. By doing so, you not only save precious time but also pave the way for more creative endeavors in your game development journey.
