Struct bevy::ecs::system::ResMut [−]
pub struct ResMut<'a, T> where
T: Resource, { /* fields omitted */ }
Expand description
Unique mutable borrow of a resource.
See the World
documentation to see the usage of a resource.
If you need a shared borrow, use Res
instead.
Panics
Panics when used as a SystemParam
if the resource does not exist.
Use Option<ResMut<T>>
instead if the resource might not always exist.
Implementations
pub fn into_inner(self) -> &'a mut T
pub fn into_inner(self) -> &'a mut T
Consume self
and return a mutable reference to the
contained value while marking self
as “changed”.
Trait Implementations
impl<'a, T> DetectChanges for ResMut<'a, T> where
T: Resource,
impl<'a, T> DetectChanges for ResMut<'a, T> where
T: Resource,
Returns true if (and only if) this value been added since the last execution of this system. Read more
pub fn is_changed(&self) -> bool
pub fn is_changed(&self) -> bool
Returns true if (and only if) this value been changed since the last execution of this system. Read more
pub fn set_changed(&mut self)
pub fn set_changed(&mut self)
Manually flags this value as having been changed. This normally isn’t required because accessing this pointer mutably automatically flags this value as “changed”. Read more
