bevymod2d_hierarchy

Bevy plugin for more ergonomic 2D.

• Specialized 2D transform and propagation systems.
• Independent of the Bevy 3D transform, can use both in the same project.
• Compatible with existing plugins as long as they only query for GlobalTransform and not Transform.
• Control 2D transform propagation behaviour.
• Performance similar to the 3D Transform. The propagation control has a cost, but some operations cheaper in 2D.
• No quaternions.
• Supports Bevy 0.8

Usage

Add the dependency to your Cargo.toml toml [dependencies] bevy_mod_2d_hierarchy = "0.2"

Add the plugin to your Bevy App: ```rust use bevy::prelude::; use bevy_mod_2d_hierarachy::prelude::;

fn main() { App::new() .addplugins(DefaultPlugins) .addplugin(Transform2dPlugin) // .. rest of systems etc .run(); } ```

Then spawn some sprites

rust pub fn spawn( mut commands: Commands, asset_server: Res<AssetServer>, ) { commands.spawn_bundle(Camera2dBundle2::default()); commands.spawn_bundle(SpriteBundle2 { texture: asset_server.load("sprite.png"), transform2: Transform2::from_rotation(0.5 * std::f32::consts::PI).with_scale(3.), ..Default::default() }) .with_children(|builder| { builder.spawn_bundle(SpriteBundle2 { sprite: Sprite { color: Color::YELLOW, ..Default::default() }, texture: asset_server.load("sprite.png"), transform2: Transform2::from_xy(0., 32.), propagate: Propagate::TRANSLATION, ..Default::default() }); }); }
