Struct gdnative::api::MultiMeshInstance

pub struct MultiMeshInstance { /* fields omitted */ }

core class MultiMeshInstance inherits GeometryInstance (unsafe).

Official documentation

See the documentation of this class in the Godot engine's official documentation.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

MultiMeshInstance is a reference-only type. Persistent references can only exist in the unsafe Ref<MultiMeshInstance> 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

MultiMeshInstance inherits methods from:

• GeometryInstance
• VisualInstance
• Spatial
• Node
• Object

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

impl MultiMeshInstance

pub fn new() -> Ref<MultiMeshInstance, Unique>

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.

pub fn multimesh(&self) -> Option<Ref<MultiMesh, Shared>>

The [MultiMesh] resource that will be used and shared among all instances of the [MultiMeshInstance].

pub fn set_multimesh(&self, multimesh: impl AsArg<MultiMesh>)

The [MultiMesh] resource that will be used and shared among all instances of the [MultiMeshInstance].

Trait Implementations

impl Debug for MultiMeshInstance

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Deref for MultiMeshInstance

type Target = GeometryInstance

The resulting type after dereferencing.

fn deref(&self) -> &GeometryInstance

Dereferences the value.

impl DerefMut for MultiMeshInstance

fn deref_mut(&mut self) -> &mut GeometryInstance

Mutably dereferences the value.

impl GodotObject for MultiMeshInstance

type RefKind = ManuallyManaged

The memory management kind of this type. This modifies the behavior of the Ref smart pointer. See its type-level documentation for more information.

fn class_name() -> &'static str

fn null() -> Null<Self>

Creates an explicitly null reference of Self as a method argument. This makes type inference easier for the compiler compared to Option.

fn new() -> Ref<Self, Unique> where
    Self: Instanciable, 

Creates a new instance of Self using a zero-argument constructor, as a Unique reference.

fn cast<T>(&self) -> Option<&T> where
    T: GodotObject + SubClass<Self>,

fn upcast<T>(&self) -> &T where
    Self: SubClass<T>,
    T: GodotObject,
