Controlling With Input

We'll control our player with the A and D keys on the keyboard. A changes the position of the player to the left, and D to the right.

    keyboard_input: Res<ButtonInput<KeyCode>>,
    mut player: Query<&mut Transform, With<Player>>,
) {
    let mut player_transform = player.single_mut();
    if keyboard_input.pressed(KeyCode::KeyA) {
        player_transform.translation.x -= 5.0;
    }
    if keyboard_input.pressed(KeyCode::KeyD) {
        player_transform.translation.x += 5.0;
    }
}
