pub struct VisibilityEnabler2D { /* fields omitted */ }
Expand description
core class VisibilityEnabler2D
inherits VisibilityNotifier2D
(unsafe).
Official documentation
See the documentation of this class in the Godot engine’s official documentation. The method descriptions are generated from it and typically contain code samples in GDScript, not Rust.
Memory management
Non reference counted objects such as the ones of this type are usually owned by the engine.
VisibilityEnabler2D
is a reference-only type. Persistent references can
only exist in the unsafe Ref<VisibilityEnabler2D>
form.
In the cases where Rust code owns an object of this type, for example if the object was just
created on the Rust side and not passed to the engine yet, ownership should be either given
to the engine or the object must be manually destroyed using Ref::free
, or Ref::queue_free
if it is a Node
.
Class hierarchy
VisibilityEnabler2D inherits methods from:
Safety
All types in the Godot API have “interior mutability” in Rust parlance.
To enforce that the official thread-safety guidelines are
followed, the typestate pattern is used in the Ref
and TRef
smart pointers,
and the Instance
API. The typestate Access
in these types tracks whether the
access is unique, shared, or exclusive to the current thread. For more information,
see the type-level documentation on Ref
.
Implementations
Constants
Creates a new instance of this object.
Because this type is not reference counted, the lifetime of the returned object is not automatically managed.
Immediately after creation, the object is owned by the caller, and can be
passed to the engine (in which case the engine will be responsible for
destroying the object) or destroyed manually using Ref::free
, or preferably
Ref::queue_free
if it is a Node
.
If true
, the parent’s [method Node._process] will be stopped.
If true
, the parent’s [method Node._process] will be stopped.
Methods from Deref<Target = VisibilityNotifier2D>
If true
, the bounding rectangle is on the screen.
Note: It takes one frame for the node’s visibility to be assessed once added to the scene tree, so this method will return false
right after it is instantiated, even if it will be on screen in the draw pass.

The resulting type after dereferencing.
Dereferences the value.
Mutably dereferences the value.
type RefKind = ManuallyManaged
type RefKind = ManuallyManaged
Creates an explicitly null reference of Self
as a method argument. This makes type
inference easier for the compiler compared to Option
. Read more
Creates a new instance of Self
using a zero-argument constructor, as a Unique
reference. Read more
Performs a dynamic reference downcast to target type. Read more
Performs a static reference upcast to a supertype that is guaranteed to be valid. Read more
Creates a persistent reference to the same Godot object with shared thread access. Read more

Self: GodotObject<RefKind = RefCounted>,
unsafe fn assume_thread_local(&self) -> Ref<Self, ThreadLocal> where

Creates a persistent reference to the same Godot object with thread-local thread access. Read more
Creates a persistent reference to the same Godot object with unique access. Read more
Recovers a instance ID previously returned by Object::get_instance_id
if the object is
still alive. See also TRef::try_from_instance_id
