Struct bevy::prelude::Res [−]
Shared borrow of a Resource
When used as a system parameter, panics if resource does not exist.
Use Option<Res<T>>
if the resource might not always exist.
Implementations
impl<'w, T> Res<'w, T> where
T: Component,
T: Component,
pub fn is_added(&self) -> bool
Returns true if (and only if) this resource been added since the last execution of this system.
pub fn is_changed(&self) -> bool
Returns true if (and only if) this resource been changed since the last execution of this system.
