Accessing the Command Palette

Before diving into creating custom commands, let’s acquaint ourselves with the basics of initiating the command palette within the Godot editor. You can easily access the command palette using the following steps or keyboard shortcut:

Editor > Command Palette
// or use the shortcut (Godot default is Shift + Cmd/Ctrl + P)

Once opened, the command palette will display a list of commands you can execute. You can start typing to filter through the commands, and pressing ‘Enter’ will execute the selected one.

Adding Custom Commands

Adding your own commands to the EditorCommandPalette is not only possible but also incredibly simple. You can do so by creating a new EditorPlugin and using `add_command()` method of the EditorCommandPalette. Here’s an example of how you might add a custom command:

class_name MyEditorPlugin extends EditorPlugin
var command_palette: EditorCommandPalette

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("hello", "_on_command_hello_triggered")

func _on_command_hello_triggered():
    print("Hello from the command palette!")

This code snippet illustrates how to create a custom command named “hello” that, when triggered, will print a message to the debug console.

Removing Commands

If you ever need to remove a command from the EditorCommandPalette, the `remove_command()` method comes to the rescue. For example:

func _exit_tree():
    command_palette.remove_command("hello", "_on_command_hello_triggered")

Executing the above will remove the previously added “hello” command from the palette once the plugin is disabled or removed from the editor.

Adding Shortcut Keys

You can even define shortcut keys for your commands, which can be executed directly from the keyboard. This heightens efficiency, allowing you to perform actions without opening the command palette every time. Here’s an example:

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("hello", "_on_command_hello_triggered")

    var shortcut = ShortCut.new()
    var input_event = InputEventKey.new()
    input_event.scancode = KEY_H
    shortcut.set_shortcut(input_event)
    
    command_palette.bind_command_to_shortcut("hello", shortcut)

In the snippet above, we’ve created a new shortcut that binds the “hello” command to the ‘H’ key on your keyboard.

These series of examples provide you with the foundation needed to start customizing the EditorCommandPalette to your liking. In the next part of our tutorial, we’ll expand on these concepts and explore more complex customizations, read on to take your Godot development skills to the next level!

Now that we’ve covered the essentials of adding and removing commands from the EditorCommandPalette, let’s explore more advanced features and further customize our commands.

Adding Command Categories

In a complex game development environment, your command palette can become crowded. To maintain a clean and organized workflow, you can group related commands into categories:

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("My Category/Hello", "_on_command_hello_triggered")

By including a category such as “My Category” before the command name, you create a collapsible section within the command palette that can be expanded to reveal its commands.

Updating Commands

You might need to update commands dynamically based on certain conditions within the editor. This is how you can achieve it:

func _on_some_condition_met():
    command_palette.update_command("My Category/Hello", "_on_command_hello_updated")

func _on_command_hello_updated():
    # Updated functionality for hello command

This will tell the command palette that the functionality of the “Hello” command has changed and should now trigger the `_on_command_hello_updated` method when executed.

Command Callbacks with Arguments

Sometimes, you might want to pass arguments to your command callbacks. You can do this by binding the command to a Callable:

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    var callable = Callable(self, "_on_command_hello_with_argument")
    command_palette.add_command("say_hello", callable, ["Zenva"])

func _on_command_hello_with_argument(argument):
    print("Hello " + argument + " from the command palette!")

In the above, we pass “Zenva” as an argument to our callback function, making our commands even more robust and flexible.

Command State Indicators

Godot also allows us to show the state of a command right within the command palette, like a toggle status. Here’s how you can indicate command states:

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("Toggle Feature", "_on_toggle_feature_triggered")
    command_palette.set_command_checked("Toggle Feature", true)

func _on_toggle_feature_triggered():
    var is_checked = command_palette.is_command_checked("Toggle Feature")
    command_palette.set_command_checked("Toggle Feature", !is_checked)
    # Code to enable or disable the feature

The `set_command_checked` method updates the visual representation of the command to show a checkmark next to it, which is commonly interpreted as the feature being enabled.

Custom Icons for Commands

To provide a more intuitive and visually appealing command palette, you can associate custom icons with your commands:

func _enter_tree():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("Launch Rocket", "_on_launch_rocket_pressed")
    var icon = preload("res://icons/rocket_icon.png")
    command_palette.set_command_icon("Launch Rocket", icon)

Here we’ve preloaded an icon and set it to appear next to the “Launch Rocket” command, improving the visual experience for the user.

By combining these elements, you can craft a highly effective, customized command palette that aligns with the specific needs of your project and personal workflow preferences. As with any powerful tool, the more you know and use it, the more it will enhance your productivity and the enjoyment you get from using Godot as your game development platform.

Keep experimenting with these command palette customizations and integrate them into your EditorPlugin. Before you know it, you’ll wonder how you ever worked without it! Happy coding and game creating with Godot and the EditorCommandPalette!

We’ve covered basic to advanced features of the EditorCommandPalette, but let’s take it further. Beyond adding commands and categories, configuring shortcuts, and setting command states, Godot’s extensibility allows for robust customization. Below are more code examples and explanations that will enhance your command palette experience.

Dynamically Generating Commands

In some cases, you might want commands to be generated dynamically based on the project’s current state or user actions. Here’s how you could dynamically add a series of commands:

func _generate_dynamic_commands():
    var commands = ["Launch", "Build", "Test"]
    for command in commands:
        var name = "Dynamic/" + command
        command_palette.add_command(name, "_on_dynamic_command", [command])

func _on_dynamic_command(command_name):
    print("Executing " + command_name)

This approach lets you create a suite of related commands quickly. For instance, you can have a set of commands for different build configurations or levels in a game.

Controlling Command Visibility

Commands may not always be relevant and you could clutter the palette if all commands appear at all times. Here’s how you can control the visibility of commands:

func _update_command_visibility():
    var can_save = _can_perform_save()
    command_palette.set_command_visible("File/Save", can_save)

func _can_perform_save():
    # Return true if save operation is currently valid
    return true # Replace with actual validation

This code conditionally shows or hides the “Save” command based on the return value of `_can_perform_save`. It’s a handy way to prevent users from attempting operations that are not currently possible.

Registering Editor Shortcuts

For invoking commands through keyboard shortcuts defined in Godot’s InputMap, here is an example:

func _register_editor_shortcuts():
    command_palette = EditorCommandPalette.new()
    command_palette.add_command("Make Coffee", "_on_make_coffee_triggered")
    var shortcut = EditorSettings.get_singleton().get_shortcut("editor/make_coffee")
    command_palette.bind_command_to_shortcut("Make Coffee", shortcut)

func _on_make_coffee_triggered():
    print("Coffee is brewing!")

In this snippet, we’ve created a new command that is bound to a keyboard shortcut which is defined in the editor’s settings, adding another level of customization.

Responding to the Editor’s Signals

Commands can also respond to the editor’s signals, such as when a script is saved or the scene changes:

func _connect_editor_signals():
    command_palette = EditorCommandPalette.new()
    
    get_editor_interface().connect("scene_changed", self, "_on_scene_changed")
    get_editor_interface().connect("script_saved", self, "_on_script_saved")

func _on_scene_changed():
    # Update commands based on the currently edited scene

func _on_script_saved():
    # Update commands based on recent changes

These signals allow for updating or adding commands based on real-time changes within the editor, making your palette more contextually aware.

Putting these techniques into practice, your EditorCommandPalette becomes a tailored control center, bending to the needs of your game development environment. The upshot is a tool that not only aids in game creation but also increases the speed and pleasure of the development process. Use these strategies to sharpen your Godot development toolkit, and turn the EditorCommandPalette into an indispensable ally in your game development journey.
