⚠️ 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.

Basic Audio

Load and play an audio file at application startup.

Introduction

Playing audio in PyBevy is simple — load an audio file with the AssetServer and spawn an AudioPlayer entity to start playback.

from pybevy.prelude import *
from pybevy.audio import AudioPlayer, AudioSource

Setup

def setup(commands: Commands, asset_server: AssetServer) -> None:
    commands.spawn(AudioPlayer(asset_server.load("sounds/Windless Slopes.ogg", AudioSource)))

Running the App

@entrypoint
def main(app: App) -> App:
    return app.add_plugins(DefaultPlugins).add_systems(Startup, setup)
 
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 basic_audio.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.
