fn get_aabb(&self) -> Aabb

Virtual method to override the AABB for a custom class extending Mesh.

Provided Methods

fn init(base: Base<Self::Base>) -> Self

Godot constructor, accepting an injected base object.

base refers to the base instance of the class, which can either be stored in a Base<T> field or discarded. This method returns a fully-constructed instance, which will then be moved into a Gd<T> pointer.

If the class has a #[class(init)] attribute, this method will be auto-generated and must not be overridden.

fn on_notification(&mut self, what: ObjectNotification)

Called when the object receives a Godot notification.

The type of notification can be identified through what. The enum is designed to hold all possible NOTIFICATION_* constants that the current class can handle. However, this is not validated in Godot, so an enum variant Unknown exists to represent integers out of known constants (mistakes or future additions).

This method is named _notification in Godot, but on_notification in Rust. To send notifications, use the Object::notify method.

See also in Godot docs:

• Object::_notification.
• Notifications tutorial.

fn on_get(&self, property: StringName) -> Option<Variant>

Called whenever get() is called or Godot gets the value of a property.

Should return the given property’s value as Some(value), or None if the property should be handled normally.

See also in Godot docs:

• Object::_get.

fn on_set(&mut self, property: StringName, value: Variant) -> bool

Called whenever Godot set() is called or Godot sets the value of a property.

Should set property to the given value and return true, or return false to indicate the property should be handled normally.

See also in Godot docs:

• Object::_set.

fn on_validate_property(&self, property: &mut PropertyInfo)

Called whenever Godot retrieves value of property. Allows to customize existing properties. Every property info goes through this method, except properties added with on_get_property_list().

Exposed property here is a shared mutable reference obtained (and returned to) from Godot.

See also in the Godot docs:

• Object::_validate_property

fn on_get_property_list(&mut self) -> Vec<PropertyInfo>

Available on since_api=4.3 only.

Called whenever Godot get_property_list() is called, the returned vector here is appended to the existing list of properties.

This should mainly be used for advanced purposes, such as dynamically updating the property list in the editor.

See also in Godot docs:

• Object::_get_property_list

fn on_property_get_revert(&self, property: StringName) -> Option<Variant>

Called by Godot to tell if a property has a custom revert or not.

Return None for no custom revert, and return Some(value) to specify the custom revert.

This is a combination of Godot’s Object::_property_get_revert and Object::_property_can_revert. This means that this function will usually be called twice by Godot to find the revert.

Note that this should be a pure function. That is, it should always return the same value for a property as long as self remains unchanged. Otherwise, this may lead to unexpected (safe) behavior.

fn to_string(&self) -> GString

String representation of the Godot instance.

Override this method to define how the instance is represented as a string. Used by impl Display for Gd<T>, as well as str() and print() in GDScript.

fn create_mesh_array(&self) -> AnyArray

Override this method to customize how this primitive mesh should be generated. Should return an Array where each element is another Array of values required for the mesh (see the [enum Mesh.ArrayType] constants).

fn setup_local_to_scene(&mut self)

Override this method to customize the newly duplicated resource created from instantiate, if the original’s [member resource_local_to_scene] is set to true.

Example: Set a random damage value to every local resource from an instantiated scene:

extends Resource

var damage = 0

func _setup_local_to_scene():
	damage = randi_range(10, 40)

fn get_rid(&self) -> Rid

Override this method to return a custom RID when get_rid is called.

fn reset_state(&mut self)

For resources that store state in non-exported properties, such as via on_validate_property or on_get_property_list, this method must be implemented to clear them.

fn set_path_cache(&self, path: GString)

Override this method to execute additional logic after set_path_cache is called on this object.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
