Function bevy_ecs::schedule::common_conditions::not
source · pub fn not<Marker, TOut, T>(condition: T) -> NotSystem<T::System>
Expand description
Generates a Condition
that inverses the result of passed one.
§Example
app.add_systems(
// `not` will inverse any condition you pass in.
// Since the condition we choose always returns true
// this system will never run
my_system.run_if(not(always)),
);
fn my_system(mut counter: ResMut<Counter>) {
counter.0 += 1;
}
fn always() -> bool {
true
}
app.run(&mut world);
assert_eq!(world.resource::<Counter>().0, 0);
