InputEventJoypadButton in Godot – Complete Guide

When diving into the realm of game development, mastering the art of input handling is crucial for creating immersive gaming experiences. From tapping on a screen to pressing a button on a controller, the way our games respond to user interactions can make or break player engagement. That’s where Godot 4’s InputEventJoypadButton comes into play—a class designed to handle gamepad button interactions with precision and ease. Whether you’re a budding game developer or a seasoned programmer, understanding how to leverage this functionality can add a layer of polish to your projects that players will undoubtedly appreciate.

What Is InputEventJoypadButton?

InputEventJoypadButton is a class belonging to the powerful Godot Engine, specifically tailored for managing gamepad button input. With the increasing popularity of console and PC gaming, the need to incorporate gamepad support in games has never been more significant.

What Is It For?

The InputEventJoypadButton class enables developers to detect both the pressing and releasing of gamepad buttons, along with measuring the pressure applied if supported by the gamepad. This can be used to refine gameplay mechanics, such as pressure-sensitive controls or context-sensitive actions, allowing for a richer gaming experience.

Why Should I Learn It?

For anyone looking to get into game development or enhance their current skillset, understanding input handling is a vital component. Games are an interactive medium, and ensuring that players can interact with your game effortlessly and intuitively can dramatically influence the game’s success. Knowing how to effectively use the InputEventJoypadButton class ensures that your game can cater to a wide audience that prefers the tactile feedback of gamepads, further broadening its appeal.

Handling Button Presses

Let’s start by detecting when a gamepad button is pressed. To do this, we will use the _input event in Godot:

func _input(event):
    if event is InputEventJoypadButton:
        if event.pressed:
            print("Button pressed: ", event.button_index)

This code snippet checks to see if the incoming input event is a gamepad button press. If it’s pressed, we print the button’s index to the console.

Next, we need to handle button releases. This is done in a similar way:

func _input(event):
    if event is InputEventJoypadButton:
        if not event.pressed:
            print("Button released: ", event.button_index)

This alteration to the function will print a message to the console anytime a button on the gamepad is released.

Handling Button Pressure

To handle the pressure sensitivity of a gamepad button, we can use the same InputEventJoypadButton:

func _input(event):
    if event is InputEventJoypadButton:
        if event.pressed and event.pressure > 0:
            print("Button pressure: ", event.pressure, " on button: ", event.button_index)

In the above code, we’re not only checking if the button is pressed, but also if there is any pressure applied. If there’s pressure detected, it will output the pressure value and button index to the console.

Mapping Buttons To Actions

It’s generally considered best practice to map gamepad buttons to specific actions in your game. This allows for easier control configuration and provides consistency throughout your game’s controls. Here’s how you can map a button to an action in Godot:

func _ready():

func _input(event):
    if Input.is_action_just_pressed("jump"):
        print("Jump action activated!")

The first function, `_ready()`, sets up the action “jump” and binds it to the A button on the gamepad. The `_input` function then watches for the “jump” action and responds when the action is detected.

Combining Button Inputs For Complex Actions

Complex actions, like performing a special move or combo, can be triggered by a combination of button presses:

var button_combo = []

func _input(event):
    if event is InputEventJoypadButton and event.pressed:

    if button_combo.size() == 3:
        if button_combo[0] == JOY_BUTTON_X and button_combo[1] == JOY_BUTTON_Y && button_combo[2] == JOY_BUTTON_B:
            print("Special move activated!")
        button_combo = []

In this example, we collect button presses in an array and when there are three button presses detected, we check if they match a specific combo (X, then Y, then B). If the combo matches, we activate the special move. This logic can be extended or modified for different types of combo inputs.

Understanding these basics of input handling using Godot 4’s InputEventJoypadButton prepares you for creating a responsive and engaging control scheme for your games. In the next part of our tutorial, we will dive into more advanced scenarios and utilize these skills to enhance gameplay.Adding to our toolbox, let’s explore how we can manage state-based input handling. Gamepad inputs may not only trigger immediate actions, but can also change the state of characters or gameplay, which makes handling these states crucial for a polished game experience.

Managing State-Based Input

First, let’s set up a basic state system:

enum PlayerState {

var current_state = PlayerState.IDLE

func _input(event):
    if event is InputEventJoypadButton:
        if not event.pressed and event.button_index == JOY_BUTTON_A:

func change_state(state):
    current_state = state
    # Following state-specific logic here.
    print("Changed state to: ", state)

This code defines an enum for different player states. When the A button is released, we switch the player’s state to JUMPING. The `change_state` function updates our `current_state` variable and can act as a hook for more complex state management later on.

Long Presses and Holding Down Buttons

Sometimes, you might want to differentiate between a quick tap and a long press. Here’s how you might handle this:

var long_press_timer =

func _input(event):
    if event is InputEventJoypadButton:
        if event.pressed and event.button_index == JOY_BUTTON_A:
            long_press_timer.start(0.5) # Time in seconds for long press
        elif not event.pressed and event.button_index == JOY_BUTTON_A:
            if long_press_timer.is_stopped():
                print("Short press detected")

func _on_LongPressTimer_timeout():
    print("Long press detected")

We’re using a timer to differentiate between a long press and a short press. If the button is released before the timer runs out, it’s considered a short press.

Combining Button Presses with Axis Movements

Gamepad inputs are often not just buttons but include axis movement from sticks. The following example illustrates how you can combine button presses with axis input:

func _input(event):
    if event is InputEventJoypadMotion and event.axis == JOY_AXIS_0:
        if event.axis_value < -0.5:
            print("Moving left")

func _input(event):
    if event is InputEventJoypadButton:
        if event.pressed and event.button_index == JOY_BUTTON_X:
            if Input.get_joy_axis(event.device, JOY_AXIS_0) < -0.5:
                print("Running attack to the left!")

This checks for movement on the left analog stick and a press of the X button to execute a running attack to the left.


To improve the player’s experience, especially if they are using analog sticks, it’s essential to implement deadzones:

const DEADZONE = 0.15

func _input(event):
    if event is InputEventJoypadMotion and abs(event.axis_value) > DEADZONE:
        print("Axis movement detected with value: ", event.axis_value)

This small check ensures that very slight movements of the joystick (like unintentional nudges) don’t register as input.

Our journey into gamepad input handling isn’t over yet! These examples serve as a foundation for creating dynamic and responsive gameplay mechanics, but there’s always more to learn and implement. Stay tuned for further explorations into the interactivity of games with Godot 4, where we’ll tackle even more advanced input scenarios and how to finesse them into creating truly immersive gaming experiences for your players.Indeed, as we delve deeper into gamepad interactions, the next logical step involves handling more complex scenarios that provide a stronger narrative and gameplay impact. Here we will look into handling simultaneous button presses, gamepad vibrations for haptic feedback, gamepad disconnection handling, and customizable control schemes.

Simultaneous Button Presses for Combo Moves

In action games especially, players might be required to press multiple buttons at the same time to perform combo moves. Let’s see how to implement a simple simultaneous button press detection system:

func _input(event):
    if event is InputEventJoypadButton and event.pressed:
        if Input.is_action_pressed("punch") and event.button_index == JOY_BUTTON_B:
            print("Punch-kick combo!")

Gamepad Vibration

Gamepad vibration is an excellent way to provide users with haptic feedback:

func apply_vibration(strength: float, duration: float):
    if Input.is_joy_vibration_supported():
        Input.start_joy_vibration(0, strength, duration)

# To use the function:
apply_vibration(1.0, 0.5)  # Full strength, half a second

Remember, the first argument to the `start_joy_vibration` function is the device index. Adjust it accordingly if you’re working with multiple gamepads.

Handling Gamepad Disconnection

It’s important to handle cases where the gamepad gets disconnected during gameplay:

func _notification(what):
    if what == MainLoop.NOTIFICATION_WM_FOCUS_OUT:
        # Handle gamepad disconnection state here.
        print("Gamepad disconnected!")

We can use Godot’s built-in notifications to detect when the gamepad connection is lost and respond appropriately.

Customizable Control Schemes

A robust game includes customizable control schemes. Here’s a basic framework for changing the button configuration:

var action_to_button_map = {
    "jump": JOY_BUTTON_A,
    "attack": JOY_BUTTON_X

func set_button_for_action(action_name, button_index):
    action_to_button_map[action_name] = button_index

func _input(event):
    if event is InputEventJoypadButton and event.pressed:
        for action_name, button_index in action_to_button_map.items():
            if event.button_index == button_index:
                print(action_name, "action performed")

This lets us map different actions to different buttons, providing a customizable control scheme for our players.

Remember that to ensure a smooth gaming experience, you should always test your input handling with different gamepad models and in various gaming environments. As we continue on this quest to master Godot’s input event management, we’ve now covered a wide range of scenarios to help you create a rich and engaging input system in your games.
