Camera 2D

To draw 2-dimensional objects including images and any kind of shapes, we need to spawn a Camera2dBundle.

use bevy::{
    app::{App, Startup},
    core_pipeline::core_2d::Camera2dBundle,
    ecs::system::Commands,
    DefaultPlugins,
};

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

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

The Camera2dBundle contains a Camera component. The component decides where to draw 2-dimensional objects, such as on which window and on which rectangular area of the window. The default is to draw on the whole primary window.
