Example
Without bevy_mod_check_filter
:
#[derive(Component)]
struct Poisoned;
#[derive(Component)]
struct Name { name: &'static str }
fn all_poisoned(entities: Query<&Name, With<Poisoned>>) {
// ...
}
With bevy_mod_check_filter
:
#[derive(Component)]
struct Poisoned(pub bool);
impl std::ops::Deref for Poisoned {
type Target = bool;
fn deref(&self) -> &Self::Target {
&self.0
}
}
#[derive(Component)]
struct Name { name: &'static str }
fn all_poisoned(entities: Query<&Name, Check<Poisoned, Is<true>>>) {
// ...
}
// OR with one of the provided type aliases:
fn find_poisoned(entities: Query<&Name, IsTrue<Poisoned>>) {
// ...
}
