⚠️ 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.

Empty Defaults

An app with default plugins that opens a window and runs until closed.

Introduction

Adding DefaultPlugins gives you a window, rendering, input handling, asset loading, and time management. The app opens a window and runs the event loop until you close it.

from pybevy.prelude import *

Running with Defaults

@entrypoint
def main(app: App) -> App:
    return app.add_plugins(DefaultPlugins)
 
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 empty_defaults.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.
