bevy_generative

bevy_generative is a plugin written for the bevy engine that allows real-time procedural generation of maps, textures, terrain, planets and more!

Features

• Allows procedural generation of assets which can be directly integrated in your bevy game
• Handles real-time updating of image and mesh data as configuration for the asset changes
• Builds on native as well as wasm targets
• Allows saving generated assets (uses rfd for native, javascript blob for wasm)
• Serializes and deserializes components using serde

Showcase

Check out Procedra [Source], a procedural generation web application that allows you to experiment with all the parameters and generate assets in real-time!

Installation

Add bevy_generative to your rust project

Examples

Maps and Textures

use bevy::prelude::*;
use bevy_generative::map::{MapBundle, MapPlugin};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins(MapPlugin)
        .add_systems(Startup, setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn(Camera2dBundle::default());
    commands.spawn(MapBundle::default());
}

Terrain

use bevy::prelude::*;
use bevy_generative::terrain::{TerrainBundle, TerrainPlugin};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins(TerrainPlugin)
        .add_systems(Startup, setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn(PointLightBundle {
        transform: Transform::from_xyz(-2.0, 2.5, 5.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..default()
    });
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(-2.0, 2.5, 5.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..default()
    });
    commands.spawn(TerrainBundle::default());
}

Planets

use bevy::prelude::*;
use bevy_generative::planet::{PlanetBundle, PlanetPlugin};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugins(PlanetPlugin)
        .add_systems(Startup, setup)
        .run();
}

fn setup(mut commands: Commands) {
    commands.spawn(PointLightBundle {
        transform: Transform::from_xyz(-2.0, 2.5, 5.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..default()
    });
    commands.spawn(Camera3dBundle {
        transform: Transform::from_xyz(-2.0, 2.5, 5.0).looking_at(Vec3::ZERO, Vec3::Y),
        ..default()
    });
    commands.spawn(PlanetBundle::default());
}
