⚠️ Beta State

PyBevy is in an early and experimental stage. The API is incomplete, subject to breaking changes without notice, and you should expect bugs. Many features are still under development.

Gamepad Input Events

Print gamepad connection, button, and axis events as they occur.

Introduction

Event-based gamepad input gives you continuous analog values for sticks and triggers, plus connection/disconnection notifications.

from pybevy.prelude import *
from pybevy.input import GamepadConnection, GamepadAxisChanged, GamepadButtonChanged

Event System

def gamepad_events(
    connections: MessageReader[GamepadConnection],
    axes: MessageReader[GamepadAxisChanged],
    buttons: MessageReader[GamepadButtonChanged],
) -> None:
    for event in connections.read():
        print(f"Gamepad: {event}")
 
    for event in axes.read():
        print(f"Axis {event.axis}: {event.value:.3f}")
 
    for event in buttons.read():
        print(f"Button {event.button}: {event.value:.3f}")

Running the App

@entrypoint
def main(app: App) -> App:
    return app.add_plugins(DefaultPlugins).add_systems(Update, gamepad_events)
 
if __name__ == "__main__":
    main().run()

Running this example

Use PyBevy's hot reload feature to run and develop this example. If you don't have PyBevy installed, check out the Quick Start guide.

$pybevy watch gamepad_input_events.py

The code will reload automatically when you make changes to the file.

From Python to Rust

Notice how the core concepts in the code—Commands, Assets, App, and Systems—are identical to the original Bevy example?

This is the power of pybevy! It lets you learn Bevy's powerful, data-driven architecture in friendly Python.

When your project grows and you're ready for maximum, native performance, you'll already know the concepts to start writing systems in Bevy Engine with Rust.
