⚠️ 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.

Sprite Flipping

Displays a sprite flipped horizontally using the flip_x property.

Introduction

Sprites can be flipped on their X or Y axis without modifying the source image. This is useful for character animations — flip the sprite instead of creating mirrored art.

from pybevy.prelude import *

Flipping a Sprite

Set flip_x=True to mirror the sprite horizontally. You can also set flip_y=True to flip it vertically.

def setup(commands: Commands, asset_server: AssetServer) -> None:
    commands.spawn(Camera2d())
    commands.spawn(
        Sprite(
            image=asset_server.load_image("branding/bevy_bird_dark.png"),
            flip_x=True,
            flip_y=False,
        )
    )

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 sprite_flipping.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.
