Struct rin::ecs::operators::HasOption [−][src]
pub struct HasOption<T> where
T: 'static, { /* fields omitted */ }
Operator that matches every entity no matter if it has the component or not but doesn’t give access to the component, only returns a boolean specifying if the component is present or not.
This doesn’t lock the accessed component so it can be used in parallel even with write access operators
for (has_pos, vel) in entities.iter_for::<(HasOption<Position>, Read<Velocity>)>(){ if has_pos { // ... } }
Will select all entities that optionally have Position and have a Velocity component pos will be false for those that don’t have Position
