bevy_light_2d

A general purpose 2d lighting plugin for bevy. Designed to be simple to use, yet expressive enough to fit a variety of needs.

Features

• Component driven design
• Configurable point lights
• Camera specific ambient light
• Single camera rendering

Usage

In the basic example, all we need is the plugin, a camera, and a light source.

# Cargo.toml
[dependencies]
bevy = "0.13"
bevy_light_2d = "0.1"

use bevy::prelude::*;
use bevy_light_2d::prelude::*;

fn main() {
    App::new()
        .add_plugins((DefaultPlugins, Light2dPlugin))
        .add_systems(Startup, setup)
        .run()
}

fn setup(mut commands: Commands) {
    commands.spawn(Camera2dBundle::default());
    
    commands.spawn(PointLight2dBundle {
        point_light: PointLight2d {
            radius: 100.0,
            intensity: 3.0,
            ..default()
        },
        ..default()
    });
}

Motiviation

When I first started experimenting with Bevy, the lack of a first party 2d lighting implementation left me wanting. While there were some rather impressive experimental 2d lighting crates out there, there wasn't much in the way of drop in options available.

My goal with this crate is to fill that void, prioritizing ease of use and general application over depth of features.

Future goals

• Light occluders + shadows
• Sprite lights
