EditorScriptPicker in Godot – Complete Guide

In the ever-evolving world of game design and development, having the right tools to streamline your workflow can make all the difference. This is where knowledge about Godot’s various classes and controls comes into play — particularly when we delve into the realm of the Godot editor itself. A newcomer might wonder what role these components serve and how they can optimize the game development process.

In this tutorial, we’ll explore the somewhat specialized but highly useful EditorScriptPicker class in Godot 4. A deeper understanding of these tools won’t just make your life easier — they’ll empower you to customize and enhance your development experience in the Godot Engine.

What is EditorScriptPicker?

The EditorScriptPicker class is a component within the Godot Engine, a beloved open-source game development framework. Described succinctly, it’s a developer’s handy assistant for selecting and managing scripts attached to nodes within the Godot editor.

What is it for?

This class specializes in the editing of the ‘script’ property of a Node, allowing developers to efficiently attach scripts without the hassle of navigating through numerous clicks and menus. It streamlines the script attachment process, making it more intuitive and accessible directly from the Inspector dock.

Why Should I Learn About It?

Whether you are taking your first steps in Godot or you’re an experienced developer, understanding the EditorScriptPicker class can significantly enhance the way you interact with the editor. It simplifies the process of attaching and managing scripts, which is a frequent task during game development. This knowledge can save you time and allow for a more productive, less cumbersome editing flow. Let’s begin our dive into this valuable aspect of Godot!

Getting Started with the EditorScriptPicker

Upon initiating your journey with the EditorScriptPicker, the first step is to access this feature within the context of the editor. Here’s a simple example showing how to locate and work with the Inspector where your EditorScriptPicker will be used:

// The following two lines assume you have a node selected
// and you wish to attach a script to it using the editor.
EditorProperty script_property = new EditorPropertyScript();
EditorScriptPicker script_picker = new EditorScriptPicker();

This script assumes you have already selected a node to work with. What we’re doing here is initializing a new `EditorPropertyScript` instance which is a control for editing script properties, followed by creating an `EditorScriptPicker` to attach a script to the selected node.

Attaching a Script Using EditorScriptPicker

It’s time to move a step further—actually picking and attaching a script to a node. The following snippet demonstrates how to prompt the user to select a script file from the filesystem and then attach it to a node:

// Assuming 'node' is the reference to your selected node
script_picker.connect("script_selected", this, "on_script_selected");

// This is the callback function when a script is selected
func on_script_selected(script_res: Script):

Here, we connect the `script_selected` signal of the script_picker to a function named `on_script_selected` which takes the selected script resource (`script_res`) and sets it as the script for our node.

Customizing the Script Selection Process

Godot’s EditorScriptPicker also allows for customization of the script selection process. You might want to filter the scripts that can be selected or provide a default directory. Here’s an example of how to narrow the picker to .gd scripts in a specific folder on your filesystem:


This example sets a filter for only `.gd` files to be shown in the picker and changes the directory that the file browser will start in to `/scripts/` located in the resource path of your project.

Handling The `script_selected` Signal

When a script is selected, the EditorScriptPicker emits the `script_selected` signal. A properly constructed handler for this signal can assist in handling the script once it’s selected:

func _on_script_selected(selected_script: Script):
    print("A script was selected: ", selected_script.resource_path)
    // Additional handling logic can be placed here

In this function, we print the path of the selected script resource. This is where you would write additional logic to handle what happens after a script is selected, such as updating the editor UI or processing the script data further.All right, let’s dive deeper by introducing more complex operations and achieving advanced customizations with the EditorScriptPicker class. Remember, understanding and utilizing these techniques will increase your efficiency and customization capabilities within the Godot Editor. Here are some insightful examples.

Advanced Script Filtering

While we’ve seen how to filter for `.gd` scripts, there may be scenarios where you have scripts for different node types, and you want to be more specific. Let’s filter scripts based on the type of node you’re attaching them to:

var node_type = "KinematicBody2D"

This code snippet tells the EditorScriptPicker to only display scripts that are meant for `KinematicBody2D` nodes, enhancing the relevance of the choices presented to the developer.

Integrating EditorScriptPicker with Custom UI

EditorScriptPicker is flexible enough that it can be integrated into your own custom user interface. Below is how you could add it to a custom panel:

var custom_panel = Panel.new()
var script_picker = EditorScriptPicker.new()

By using `add_child()`, you can place the picker onto any UI component. This means you can create your own dialogs or panels with an embedded script picker, fitting naturally into your unique editor extensions or plugins.

Refreshing the ScriptPicker UI

After setting various filters or making changes to the settings of the EditorScriptPicker, it’s a good practice to refresh the UI to reflect the updates:


The above `update_tree()` method updates the visual representation of the picker, ensuring that any applied filters or adjustments are visible to the user immediately.

Responding to Cancellation

Sometimes, a user might change their mind and cancel the script selection process. Let’s handle this scenario:

script_picker.connect("script_selected", this, "on_script_selected");
script_picker.connect("cancelled", this, "on_picker_cancelled");

// This function is called if the script picking is cancelled
func on_picker_cancelled():
    print("The script selection was cancelled.")

By connecting the `cancelled` signal of the EditorScriptPicker to a function called `on_picker_cancelled`, you can handle the event when the user decides not to pick a script after all.

Preselecting a Specific Script

There might be times when you want the picker to start with a preselected script. Perhaps it’s the most frequently used script or the last one you worked on. Here’s how to set it up:

var default_script = preload("res://default_script.gd")

In this code, the `set_current_script()` method preselects a `default_script` once the script picker UI is invoked. This gives the developer a starting point, reducing the number of steps to reach their intended script.

Using the EditorScriptPicker in Practical Scenarios

Let’s illustrate how the EditorScriptPicker could be practically employed in a plugin. Below is a sample where we’ve created a plugin tool that allows for quick script attachment:

// Assuming this is part of a plugin script with tool mode enabled

func _ready():
    var script_picker = EditorScriptPicker.new()
    script_picker.connect("script_selected", self, "_on_script_assigned")

func _on_script_assigned(script):
    if script and get_selected_node():

With this simple setup, every time you select a script using the picker in your plugin, the script will be automatically assigned to the currently selected node in your scene.

By mastering the use of EditorScriptPicker through these examples, you are enhancing your abilities to navigate and manipulate the Godot Editor, tailoring it to your project’s specific needs and your personal workflow preferences. Remember that the more comfortable you are with these classes and tools, the more you can focus on what truly matters – creating amazing games!Moving forward, let’s delve into some additional practical examples utilizing the EditorScriptPicker. These examples will further illustrate how you might use this class in a variety of scenarios, enhancing your development process within Godot.

Sorting and Ordering Scripts

One of the valuable features for the EditorScriptPicker is the ability to sort or order scripts. This is handy when dealing with a large project that has numerous scripts.

// Implementing a simple alphabetical sorting based on the script name

Here, we’re instructing the script picker to sort the scripts alphabetically. It’s essential for finding scripts quickly, especially in a project with a vast library of scripts.

Creating a Custom Script from EditorScriptPicker

There might be instances when you realize the script you need doesn’t exist yet while using the picker. Rather than leaving the picker to create a new script manually, you can do this directly from the EditorScriptPicker interface:

// Assuming this is part of a script handling the EditorScriptPicker
script_picker.connect("script_created", this, "on_script_created");

// The callback function when a new script is created
func on_script_created(new_script_path): 
    var new_script = load(new_script_path)
    print("New script created at: " + new_script_path)
    // Here you could add additional logic to edit or assign the script

With this setup, whenever a new script is created using the ‘Create’ button in the EditorScriptPicker dialog, our callback function `on_script_created` is called, allowing us to handle the new script appropriately.

Implementing Undo/Redo for Script Assignments

Godot’s robust undo/redo system is also supported when using the EditorScriptPicker through the Editor’s `undo_redo` object, which allows you to create actions that can be undone or redone. Here’s an example of how to integrate this:

// Assume this is within a function that assigns a script to a node
var undo_redo = get_undo_redo()  // get_undo_redo is a hypothetical function to retrieve the Editor's undo_redo instance
undo_redo.create_action("Assign Script")
undo_redo.add_do_method(node, "set_script", script_res)
undo_redo.add_undo_method(node, "set_script", node.get_script())

By creating an undo/redo action, we ensure that any script assignments can be rolled back, providing a safer editing environment.

Creating Filters for Specific Project Use Cases

It might be useful to filter scripts based on specific conditions related to your project. Below is an example where we want to show only scripts that inherit from a custom class `PlayerCharacter`:

// Let's say you have a custom script 'PlayerCharacter.gd'
// and you want to pick scripts that extend this custom class.

This code filters the scripts to only those that extend `PlayerCharacter.gd`, simplifying the process of assigning character-specific scripts.

By gaining a firm grasp on these examples, you’re equipped to tailor the EditorScriptPicker to fit a variety of scenarios specific to your Godot projects. This empowerment not only streamlines your workflow but also enables you to infuse your game development process with precision and efficiency. Your investment in mastering these tools will pay dividends as you minimize mundane tasks and maximize creativity in your Godot-powered game development journey.
