TextEdit in Godot – Complete Guide

Managing text input and display is a fundamental aspect of game development, particularly for creating UI elements, dialogue systems, and much more. As you venture into the world of game creation with Godot, understanding the capabilities of built-in classes like TextEdit becomes an invaluable asset.

What is TextEdit?

Unlocking the Power of Text in Godot

TextEdit is a versatile class in Godot’s rich UI system, specifically tailored for multiline text editing. Whether you’re looking to implement a script editor within your game, a complex chat interface, or just a simple note-taking feature, TextEdit provides the necessary tools to get the job done.

Sculpting Game Experiences with Text

At the core of player interaction, text-based elements play a pivotal role. From storytelling to information delivery, the manner in which text is handled can greatly influence the player’s experience. That’s where TextEdit shines, giving developers control over text input, highlighting, and even syntax highlighting support for budding code editors.

Why Embrace TextEdit for Your Godot Projects?

Learning to harness the capabilities of TextEdit empowers you to craft detailed and responsive text interfaces, something that’s integral in today’s game designs. For both beginners and seasoned developers, understanding TextEdit is a stepping stone to creating fully-fledged in-game systems that are robust and user-friendly.

With Godot’s well-documented classes and our hands-on examples, even if you’re at the early stages of your game development journey, we’re confident you’ll quickly get to grips with how TextEdit can play a crucial role in your projects.

Initializing TextEdit in Your Scene

Firstly, let’s start by adding a TextEdit node to your scene. This will be the cornerstone of our interactive text feature.

var text_edit = TextEdit.new()

With the node added, you’ll want to adjust its size to fit your game’s interface. Here’s how you can set it programmatically:

text_edit.rect_min_size = Vector2(400, 300)

Setting and Retrieving Text

After placement, the next step is to manage the text within your TextEdit node. Adding text is straightforward:

text_edit.text = "Welcome to Zenva Academy! Where dreams become games."

To retrieve text, for instance, when a player submits their dialogue, simply:

var player_input = text_edit.text

Customizing Text Appearance

Customization plays a crucial role in integrating TextEdit into the aesthetic of your game. Change the font and font size like this:

var font = DynamicFont.new()
font.font_data = load("res://path_to_your_font.ttf")
font.size = 20
text_edit.add_font_override("font", font)

Got a thematic color scheme? Adapt the TextEdit to match:

text_edit.add_color_override("font_color", Color(1, 1, 1))  # White text
text_edit.add_color_override("background_color", Color(0, 0, 0))  # Black background

Handling User Input

Interactivity is key, and responding to user inputs is essential. Here’s how you can make TextEdit read-only, ideal for dialogue display:

text_edit.readonly = true

Alternatively, connect to the “text_changed” signal to trigger a function whenever the text changes:

text_edit.connect("text_changed", self, "_on_text_changed")

func _on_text_changed():
    print("The player has changed the text.")

These examples form the basic foundation of implementing a TextEdit node in your Godot project. As we dive deeper in the next part, we’ll explore more advanced features and how you can further enhance text manipulation and control within your game.

Building on the basics of TextEdit, it’s time to delve into the finer aspects of user interaction and advanced text manipulation.

Implementing Syntax Highlighting

If your game features coding or scripting mechanics, syntax highlighting can be a godsend. Here’s how to get started with a simple keyword highlighting implementation:

var keywords = ["if", "else", "func", "var"]

func _ready():
    var text_color = Color(0.76, 0.18, 0.05)  # Red color for keywords
    foreach keyword in keywords:
        text_edit.add_keyword_color(keyword, text_color)

Next, consider an undo/redo system for a user-friendly text editing experience:

func _undo():

func _redo():

You can link these to buttons or keyboard shortcuts for quick access.

Managing Selections and Cursors

Users might need to select text to copy, cut, or delete it. This is how you can programmatically handle text selection:

text_edit.select(0, 5)  # Selects text from index 0 to 5

And here’s how you can move the cursor around:

text_edit.cursor_set_line(2)  # Moves cursor to the beginning of the third line
text_edit.cursor_set_column(10)  # Moves cursor to the 11th position on the current line

If you need the cursor’s current position, utilize these methods:

var cursor_line = text_edit.cursor_get_line()
var cursor_column = text_edit.cursor_get_column()

Handling Word Wrapping and Scrolling

Word wrapping ensures text stays within the TextEdit bounds, which enhances readability:

text_edit.wrap_enabled = true

When dealing with long texts, automatic scrolling is essential:

text_edit.scroll_to_line(50)  # Automatically scrolls to line 50

For a smooth scroll effect, you might consider a method like this:

func smooth_scroll_to_line(target_line):
    # You can add smoother scrolling effects with custom code here

Search and Replace in TextEdit

Search features are especially useful for text-heavy interfaces. Here’s the basic way to search and highlight a phrase:

var result = text_edit.search("Zenva", 0, 0)
if result:
    text_edit.select(result.from_column, result.to_column, result.to_line)

Implementing replace can empower users to edit strings of text easily:

func _replace(old_value, new_value):
    var result = text_edit.search(old_value, 0, 0)
    while result:
        text_edit.replace(result.from_line, result.from_column, result.to_column, new_value)
        result = text_edit.search(old_value, result.to_line, result.to_column)

With these tools, you’re equipped to add a rich text editing component to your Godot game that can handle a variety of use cases, from simple notetaking to complex, interactive coding experiences. Remember, practice and experimentation are essential. Keep tweaking and testing, and consult the Godot documentation as you refine your features.

Enhancing the functionality of TextEdit further can yield a deeply interactive experience for players. Let’s continue by exploring additional features and providing code examples for practical applications.

Often, it’s necessary to give feedback or suggestions to the user as they type. Implementing such autocomplete functionality can be realized with the following steps:

text_edit.add_callback('completion', self, '_on_autocomplete')

var suggestions = ["Godot", "Zenva", "GameDev"]

func _on_autocomplete(prefix):
    return filter(lambda w: w.begins_with(prefix), suggestions)

You might want to handle tab input to provide a more traditional text editor experience, or for indenting code or paragraphs:

func _input(event):
    if event is InputEventKey and event.pressed and !event.echo and event.scancode == KEY_TAB:
        text_edit.insert_text_at_cursor("\t")  # Inserts a tab space

To provide users with line numbers, which are especially useful in code editors or when dealing with large documents, you can enable them like this:


Customizing the context menu allows users to interact with text through a familiar interface. Godot’s TextEdit provides a way to customize this menu:

text_edit.menu = text_edit.get_menu()  # Gets the default context menu
text_edit.menu.add_item("Custom Action", CUSTOM_ACTION_ID)
text_edit.connect("menu_option_pressed", self, '_on_menu_option')

func _on_menu_option(option):
    if option == CUSTOM_ACTION_ID:
        print("Custom action triggered!")

If your game has a dialogue system, you may need to add or remove tags dynamically:

text_edit.push_color(Color(1, 0.2, 0.2))  # Make text red
text_edit.add_text("This is an important message.")
text_edit.pop()  # Return to previous text color

Moreover, scrolling to a specific piece of text is often needed, particularly when you want to bring the player’s attention to it:

var phrase = "Zenva"
var line = text_edit.search(phrase).from_line if text_edit.search(phrase) else -1
if line >= 0:

Additionally, to tailor TextEdit to the aesthetic and functionality of your UI, you may need to hide the scrollbar when it’s not necessary:

text_edit.set_v_scroll(false)  # Hides the vertical scrollbar

These code examples show the adaptability of the TextEdit class within Godot. We at Zenva understand that practical, hands-on learning is key to mastering game development concepts. That’s why we aim to provide you with clear, concise examples that can be directly integrated into your projects, ensuring a streamlined learning experience that equips you with the skills needed to develop your vision into reality.
