Map files and Lua

This example in context
GLTF example

transform: Transform::from_xyz(0.7, 0.7, 1.0).looking_at(Vec3::new(0.0, 0.3, 0.0), Vec3::Y),

The example should be the most simple. You download the tutorial materials, place them in your game folder, load up the Bevy scene editor powered with EGUI and place the animated light entity, the camera entity, and the model. Save the map file and load it into the game. Positioning entities in 3d is typically done in 3d and anything less is not making things refreshingly simple.

fn animate_light_direction(
    time: Res<Time>,
    mut query: Query<&mut Transform, With<DirectionalLight>>,
) {
    for mut transform in &mut query {
        transform.rotation = Quat::from_euler(
            EulerRot::ZYX,
            0.0,
            time.seconds_since_startup() as f32 * std::f32::consts::TAU / 10.0,
            -std::f32::consts::FRAC_PI_4,
        );
    }
}

TAU is a double Pi apparently but I do not understand the rest of this
