Expand description

Virtual methods for class ScriptExtension.

These methods represent constructors (init) or callbacks invoked by the engine.

See also Godot docs for ScriptExtension methods.

§Specific notes for this interface

Use this in combination with the obj::script module.

Required Methods§

fn editor_can_reload_from_file(&mut self) -> bool

fn can_instantiate(&self) -> bool

fn get_base_script(&self) -> Option<Gd<Script>>

fn get_global_name(&self) -> StringName

fn inherits_script(&self, script: Gd<Script>) -> bool

fn get_instance_base_type(&self) -> StringName

unsafe fn instance_create(&self, for_object: Gd<Object>) -> *mut c_void

§Safety

This method has automatically been marked unsafe because it accepts raw pointers as parameters. If Godot does not document any safety requirements, make sure you understand the underlying semantics.

unsafe fn placeholder_instance_create( &self, for_object: Gd<Object>, ) -> *mut c_void

§Safety

This method has automatically been marked unsafe because it accepts raw pointers as parameters. If Godot does not document any safety requirements, make sure you understand the underlying semantics.

fn instance_has(&self, object: Gd<Object>) -> bool

fn has_source_code(&self) -> bool

fn get_source_code(&self) -> GString

fn set_source_code(&mut self, code: GString)

fn reload(&mut self, keep_state: bool) -> Error

fn get_documentation(&self) -> Array<Dictionary>

fn has_method(&self, method: StringName) -> bool

fn has_static_method(&self, method: StringName) -> bool

fn get_method_info(&self, method: StringName) -> Dictionary

fn is_tool(&self) -> bool

fn is_valid(&self) -> bool

fn get_language(&self) -> Option<Gd<ScriptLanguage>>

fn has_script_signal(&self, signal: StringName) -> bool

fn get_script_signal_list(&self) -> Array<Dictionary>

fn has_property_default_value(&self, property: StringName) -> bool

fn get_property_default_value(&self, property: StringName) -> Variant

fn update_exports(&mut self)

fn get_constants(&self) -> Dictionary

fn get_members(&self) -> Array<StringName>

fn is_placeholder_fallback_enabled(&self) -> bool

fn get_rpc_config(&self) -> Variant

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 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 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:

fn get_property(&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:

fn set_property(&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:

fn 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:

fn 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.

unsafe fn placeholder_erased(&mut self, placeholder: *mut c_void)

§Safety

This method has automatically been marked unsafe because it accepts raw pointers as parameters. If Godot does not document any safety requirements, make sure you understand the underlying semantics.

fn get_class_icon_path(&self) -> GString

fn get_script_method_argument_count(&self, method: StringName) -> Variant

fn is_abstract(&self) -> bool

fn setup_local_to_scene(&mut self)

Object Safety§

This trait is not object safe.
