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.
Return After Run
Execute code after a PyBevy app has exited.
Introduction
App.run() blocks until the app exits (e.g., the window is closed). Code after .run() executes once the app has shut down. This is useful for cleanup or reporting.
from pybevy.prelude import *Before and After
print("Starting PyBevy app...")
App().add_plugins(DefaultPlugins).run()
print("PyBevy app has exited. Back in main!")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.
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.
