fn setup(mut commands: Commands) {
commands.spawn((
Button,
Counter(0),
Text("Click Me".to_string()),
OnClick(moshi!([e: Entity], counter: Query<&mut Counter> => {
**counter.get_mut(e).unwrap() += 1;
}))
));
}
impl Button {
fn update(mut commands: Commands, buttons: Query<(Entity, &OnClick), Changed<Button>>) {
for (entity, callback) in buttons.iter() {
