Random Movement Example — Bevy Code

Moves an entity randomly each frame.

use bevy::prelude::*;
use rand::prelude::*;

struct Walker;

fn main() {
	App::build()
		.add_plugins(DefaultPlugins)
		.add_startup_system(setup.system())
		.add_system(random_move.system())
		.run();
}

fn setup(mut commands: Commands) {
	commands.spawn().insert(Walker).insert(Transform::default()).insert(GlobalTransform::default());
}

fn random_move(mut query: Query<&mut Transform, With<Walker>>) {
	let mut rng = thread_rng();
	for mut transform in query.iter_mut() {
		transform.translation.x += rng.gen_range(-1.0..1.0);
		transform.translation.y += rng.gen_range(-1.0..1.0);
	}
}

Bevy Language Guide

Bevy is a modern, open-source Rust game engine designed for high-performance 2D and 3D games, with a focus on ECS architecture, modularity, and cross-platform support for desktop and web.

Primary Use Cases

▸Cross-platform 2D and 3D games
▸Rust-native game projects
▸Educational games and simulations
▸Prototypes and experimental game engines
▸WebAssembly and desktop deployment

Notable Features

▸Rust-based ECS (Entity Component System)
▸Modular plugin architecture
▸wgpu renderer for 2D/3D
▸Bevy UI toolkit
▸Asset management and hot-reloading

Origin & Creator

Bevy was created by Carter Anderson and maintained by an open-source community, emphasizing Rust-native ECS and performance-focused game development.

Industrial Note

Bevy is gaining traction in Rust-native game development, educational games, indie 2D/3D games, simulations, and hobby projects where performance and safety are priorities.
