[−][src]Struct bevy_ecs::prelude::With
Query transformer skipping entities that do not have a T
component
See also QueryBorrow::with
.
Example
let mut world = World::new(); let a = world.spawn((123, true, "abc")); let b = world.spawn((456, false)); let c = world.spawn((42, "def")); let entities = world.query::<With<bool, (Entity, &i32)>>() .iter() .map(|(e, &i)| (e, i)) .collect::<Vec<_>>(); assert_eq!(entities.len(), 2); assert!(entities.contains(&(a, 123))); assert!(entities.contains(&(b, 456)));
