TextureProgressBar in Godot – Complete Guide

Welcome to our exploration of TextureProgressBar in Godot 4, a versatile class that enriches the visual feedback experience in games and applications. As a powerful component of the Godot Engine’s UI toolkit, understanding how to implement TextureProgressBar can significantly enhance the aesthetic of loading screens, health bars, and any form of progress indication. Whether you are a budding developer or a seasoned coder, getting to grips with this class will empower you to create more immersive and dynamic interfaces in your projects.

What is TextureProgressBar?


is a class within the Godot Engine that specializes in displaying progress through textures. Unlike the standard ProgressBar, which uses the Godot Theme resource for its appearance, the


utilizes up to three textures to visualize progress in a more customized way. This allows for a variety of progress bar styles, such as horizontal, vertical, and even radial progress indicators.

What is TextureProgressBar Used For?

Frequently employed in gaming environments, the


is an ideal tool for:

– Crafting aesthetically pleasing loading screens as players wait for the game to load.
– Visualizing player health, stamina, or other status effects in a more engaging manner.
– Creating custom skill cooldown UI elements that keep the player informed in real-time.

Why Should I Learn About TextureProgressBar?

Understanding how to use


offers several advantages:

– It increases the customizability and polish of your game’s UI.
– It improves the user’s visual experience with informative and pleasing feedback.
– It gives you the ability to align the UI’s aesthetic more closely with the game’s art style and theming.

Gaining proficiency with the


is not only useful for aesthetic reasons but also aids in presenting vital gameplay information in a clear and intuitive manner. Join us as we delve into this class, break down its properties, and showcase examples to broaden your UI capabilities with Godot Engine 4.

Setting Up the TextureProgressBar in Godot 4

To start using


in Godot 4, you need first to create a new node. Here’s a simple step to add a TextureProgressBar to your scene:

# Assuming you have a scene already set up and `self` refers to the current node
var texture_progress = TextureProgressBar.new()

After creating the node, the next step is to set up the textures. For this example, we will use a progress bar that fills from left to right:

texture_progress.texture_progress = load("res://path/to/progress_texture.png")
texture_progress.texture_bg = load("res://path/to/background_texture.png")
texture_progress.texture_fg = load("res://path/to/foreground_texture.png")

The progress_texture is what visually increases and decreases as progress is made. The background_texture usually represents the container of the progress bar, and the foreground_texture can be used as an overlay that doesn’t change with progress, often used to add gloss or additional decorative elements.

Manipulating Progress and Range

The true power of the


comes from its ability to show progression. You can set the value and the range to represent the progress.

# Set the range of the progress bar
texture_progress.min_value = 0
texture_progress.max_value = 100

# Update the value to reflect some progress
texture_progress.value = 50

This block of code initializes the progress bar to understand its minimum and maximum values and immediately sets the progress to half. The actual progression can be tied to game logic like loading assets, the player’s health, mana, or experience points.

Customizing the Fill Mode



offers different fill modes which dictate how the progress is displayed.

# Set the fill mode to left to right
texture_progress.fill_mode = TextureProgressBar.FILL_LEFT_TO_RIGHT

# Other fill modes include
# texture_progress.fill_mode = TextureProgressBar.FILL_RIGHT_TO_LEFT
# texture_progress.fill_mode = TextureProgressBar.FILL_TOP_TO_BOTTOM
# texture_progress.fill_mode = TextureProgressBar.FILL_BOTTOM_TO_TOP

Choosing the right fill mode will depend on the orientation and the design of your progress bar. It’s important to align this with the player’s expectations and the overall user interface design.

Animating the Progress Bar

In many situations, instantaneous changes to the progress bar may not be desirable. Instead, smooth transitions can provide a polished feel. Here’s how you can animate the progress bar value change:

# Assuming you have some method to gradually update progress
func update_progress(new_value):
    var tween = Tween.new()
    tween.interpolate_property(texture_progress, "value",

This code is using a


to animate the value property of the


over 1 second. The linear transition provides a smooth change in the progress value, improving the quality of visual feedback given to the player.

By understanding and implementing these fundamentals, you can create a fully functional and visually appealing progress bar using the


in Godot 4. Experiment with different textures, fill modes, and animations to find the perfect fit for your game’s UI.

Adding dynamic reactions to the in-game environment or user actions can significantly enhance the user experience. One way to achieve this is by controlling the visibility and progress of the


based on certain conditions. Let’s explore further how to interact with the progress bar using code examples.

Responding to User Input

If you want the progress bar to update when a user performs specific actions, such as pressing a button, you can tie an input event to update the progress bar:

func _input(event):
    if event is InputEventKey and event.pressed and event.scancode == KEY_SPACE:
        texture_progress.value += 10
        if texture_progress.value > texture_progress.max_value:
            texture_progress.value = texture_progress.max_value

Here, each time the spacebar is pressed, the progress bar’s value is increased. It’s crucial to ensure the value doesn’t exceed


, as doing so could lead to unexpected behavior.

Connecting to Signals

Godot’s signal system allows nodes to emit signals when something happens. For a more reactive


, you can connect a signal that informs the progress bar of a change.

# Connect a hypothetical 'health_changed' signal from a 'player' object
player.connect("health_changed", self, "_on_health_changed")

func _on_health_changed(new_health):
    texture_progress.value = new_health

This readily updates the progress as the player’s health changes, reflected in-game without requiring explicit polling of the player’s health status.

Using Getters and Setters

Getters and setters can manage the progress bar’s value while incorporating additional logic, such as constraints or triggering animations:

var player_health = 100 setget set_health

func set_health(value):
    player_health = clamp(value, 0, 100)
    texture_progress.value = player_health
    # Additional logic, for instance, game-over checks, could be added here

With a setter function


, you ensure the value is clamped within defined limits and the


‘s value is updated accordingly.

Modifying Texture and Style

Sometimes you may need to change the textures or styles dynamically to reflect a change in the game’s state. For instance, if the player enters a critical health state, you could change the progress bar’s texture to alert the player:

func update_health_state(is_critical):
    if is_critical:
        texture_progress.texture_progress = load("res://path/to/critical_health_texture.png")
        texture_progress.texture_progress = load("res://path/to/normal_health_texture.png")

This method swaps the actual filling texture based on the player’s health condition, immediately providing visual feedback.

All these examples illustrate how the


can be a potent tool in your UI toolkit, enabling you to provide dynamic responses and feedback in your games created with Godot 4. Remember, a well-implemented progress bar can greatly contribute to the polish and feel of your game, making the effort well worth it.

Continuing with the dynamic aspects of the


, let’s delve into more code examples focusing on advanced manipulations that can add depth to your in-game UI using Godot 4.

For an RPG or any game that features an experience system, you could visualize the progress towards the next level by updating the progress bar. Here’s a snippet that might be used within a leveling system:

func update_experience(current_exp, exp_to_next_level):
    texture_progress.value = current_exp
    texture_progress.max_value = exp_to_next_level

Progress bars aren’t limited to straightforward scenarios. Consider implementing a radial cooldown timer for abilities or buffs. The progress bar can rotate to simulate a clock ticking down:

func start_ability_cooldown(duration):
    texture_progress.fill_mode = TextureProgressBar.FILL_CLOCKWISE
    texture_progress.value = 0
    texture_progress.max_value = duration
    var timer = Timer.new()
    timer.wait_time = 1.0
    timer.one_shot = false

    timer.connect("timeout", self, "_on_Timer_timeout")

func _on_Timer_timeout():
    if texture_progress.value < texture_progress.max_value:
        texture_progress.value += 1
        texture_progress.get_node("Timer").queue_free() # Clean up after ourselves

Customizing progress bars with effects, such as a fade out when reaching full progress, can add an extra level of polish. Utilizing





func fade_out_progress_bar():
    var tween = Tween.new()
    tween.interpolate_property(texture_progress, "modulate",
                             Color(1, 1, 1, 1),
                             Color(1, 1, 1, 0),

This can be especially dramatic if combined with finishing an important game event like a boss fight or level completion.

Furthermore, you can react to the


‘s value reaching its max or min value by connecting to the



func _ready():
    texture_progress.connect("value_changed", self, "_on_value_changed")

func _on_value_changed(value):
    if value == texture_progress.max_value:
        print("Max progress reached!")
        # Possible actions include disabling the progress bar, playing an animation, or triggering a game event.

Lastly, a progress bar can be a storytelling element. For example, showing a hacker’s progress in cracking a code while the player defends against incoming threats. Such a scenario could involve updating the texture_progress visually and numerically:

func hack_progress(increase_amount):
    texture_progress.value += increase_amount
    # Maybe change texture styles based on progress for heightened tension.
    if texture_progress.value >= 75:
        texture_progress.texture_progress = load("res://path/to/urgent_hack_texture.png")
    elif texture_progress.value >= 50:
        texture_progress.texture_progress = load("res://path/to/halfway_hack_texture.png")

In all scenarios,


offers the flexibility for both functional and atmospheric purposes. It’s a valuable asset in providing players with clear and interactive feedback in Godot 4, contributing significantly to a polished and responsive game or application. Experiment with these examples and expand upon them to create unique user experiences tailored to your specific project needs.
