Struct bevy_ecs::query::Or[][src]

pub struct Or<T>(pub T);
Expand description

A filter that tests if any of the given filters apply.

This is useful for example if a system with multiple components in a query only wants to run when one or more of the components have changed.

The And equivalent to this filter is a tuple testing that all the contained filters apply instead.

Examples

fn print_cool_entity_system(query: Query<Entity, Or<(Changed<Color>, Changed<Style>)>>) {
    for entity in query.iter() {
        println!("Entity {:?} got a new style or color", entity);
    }
}

Returns true if (and only if) every table of every archetype matched by this Fetch contains all of the matched components. This is used to select a more efficient “table iterator” for “dense” queries. If this returns true, Fetch::set_table and Fetch::table_fetch will be called for iterators. If this returns false, Fetch::set_archetype and Fetch::archetype_fetch will be called for iterators. Read more
