bevy_prototype_lyon enables Bevy users to draw 2D shapes and paths, like triangles, circles, rectangles, lines, arcs and beziers.
Currently Bevy does not support drawing custom shapes in an easy way. This crate uses a variation of Bevy's SpriteBundle with custom meshes to draw shapes. The lyon crate is used to generate those custom meshes.
Add bevy_prototype_lyon to your cargo project:
cargo add bevy_prototype_lyonThen, you can start by drawing simple shapes:
use bevy::prelude::*;
use bevy_prototype_lyon::prelude::*;
fn main() {
App::new()
.insert_resource(Msaa::Sample4)
.add_plugins(DefaultPlugins)
.add_plugins(ShapePlugin)
.add_systems(Startup, setup_system)
.run();
}
fn setup_system(mut commands: Commands) {
let shape = shapes::RegularPolygon {
sides: 6,
feature: shapes::RegularPolygonFeature::Radius(200.0),
..shapes::RegularPolygon::default()
};
commands.spawn(Camera2dBundle::default());
commands.spawn((
ShapeBundle {
path: GeometryBuilder::build_as(&shape),
..default()
},
Fill::color(Color::CYAN),
Stroke::new(Color::BLACK, 10.0),
));
}Don't forget to check out the examples to learn more!
I strive to support the latest version of Bevy. Support for a version of Bevy is dropped as soon as a new one is released.
The following table shows the latest version of bevy_prototype_lyon that supports a certain version of Bevy.
