如何在bevy中旋转和移动对象

use bevy::prelude::*;

fn main() {
    App::build()
        .add_default_plugins()
        .add_startup_system(setup.system())
        .add_system(rotate.system())
        .run();
}

fn setup(commands: &mut Commands) {
    commands.spawn(SpriteBundle {
        sprite: Sprite::new(Vec2::new(100.0, 100.0)),
        transform: Transform::from_translation(Vec3::new(0.0, 0.0, 0.0)),
        ..Default::default()
    });
}

fn rotate(time: Res<Time>, mut query: Query<&mut Transform>) {
    for mut transform in query.iter_mut() {
        // 每秒旋转90度
        let rotation = Quat::from_rotation_z(time.delta_seconds() * 90.0);
        transform.rotation *= rotation;
    }
}

use bevy::prelude::*;

fn main() {
    App::build()
        .add_default_plugins()
        .add_startup_system(setup.system())
        .add_system(move_system.system())
        .run();
}

fn setup(commands: &mut Commands) {
    commands.spawn(SpriteBundle {
        sprite: Sprite::new(Vec2::new(100.0, 100.0)),
        transform: Transform::from_translation(Vec3::new(0.0, 0.0, 0.0)),
        ..Default::default()
    });
}

fn move_system(time: Res<Time>, mut query: Query<&mut Transform>) {
    for mut transform in query.iter_mut() {
        // 每秒沿X轴移动100个单位
        transform.translation.x += time.delta_seconds() * 100.0;
    }
}
