[−][src]Struct bevy_ecs::prelude::Or

pub struct Or<T>(_);

Query transformer performing a logical or on a pair of queries Intended to be used on Mutated or Changed queries.

Example

let mut world = World::new();
world.spawn((123, true, 1., Some(1)));
world.spawn((456, false, 2., Some(0)));
for mut b in world.query_mut::<Mut<i32>>().iter().skip(1).take(1) {
    *b += 1;
}
let components = world
    .query_mut::<Or<(Mutated<bool>, Mutated<i32>, Mutated<f64>, Mutated<Option<i32>>)>>()
    .iter()
    .map(|(b, i, f, o)| (*b, *i))
    .collect::<Vec<_>>();
assert_eq!(components, &[(false, 457)]);
