• open_xr_interface: sidecar module with related enum/flag types
• IOpenXrInterface: virtual methods
• SignalsOfOpenXrInterface: signal collection

See also Godot docs for OpenXRInterface.

Construction

This class is reference-counted. You can create a new instance using OpenXrInterface::new_gd().

Godot docs

The OpenXR interface allows Godot to interact with OpenXR runtimes and make it possible to create XR experiences and games.

Due to the needs of OpenXR this interface works slightly different than other plugin based XR interfaces. It needs to be initialized when Godot starts. You need to enable OpenXR, settings for this can be found in your games project settings under the XR heading. You do need to mark a viewport for use with XR in order for Godot to know which render result should be output to the headset.

Methods from Deref<Target = XrInterface>

pub fn get_name(&self) -> StringName

Returns the name of this interface ("OpenXR", "OpenVR", "OpenHMD", "ARKit", etc.).

pub fn get_capabilities(&self) -> u32

Returns a combination of [enum Capabilities] flags providing information about the capabilities of this interface.

pub fn is_primary(&self) -> bool

pub fn set_primary(&mut self, primary: bool)

pub fn is_initialized(&self) -> bool

Returns true if this interface has been initialized.

pub fn initialize(&mut self) -> bool

Call this to initialize this interface. The first interface that is initialized is identified as the primary interface and it will be used for rendering output.

After initializing the interface you want to use you then need to enable the AR/VR mode of a viewport and rendering should commence.

Note: You must enable the XR mode on the main viewport for any device that uses the main output of Godot, such as for mobile VR.

If you do this for a platform that handles its own output (such as OpenVR) Godot will show just one eye without distortion on screen. Alternatively, you can add a separate viewport node to your scene and enable AR/VR on that viewport. It will be used to output to the HMD, leaving you free to do anything you like in the main window, such as using a separate camera as a spectator camera or rendering something completely different.

While currently not used, you can activate additional interfaces. You may wish to do this if you want to track controllers from other platforms. However, at this point in time only one interface can render to an HMD.

pub fn uninitialize(&mut self)

Turns the interface off.

pub fn get_system_info(&self) -> Dictionary<Variant, Variant>

Returns a Dictionary with extra system info. Interfaces are expected to return XRRuntimeName and XRRuntimeVersion providing info about the used XR runtime. Additional entries may be provided specific to an interface.

**Note:**This information may only be available after initialize was successfully called.

pub fn get_tracking_status(&self) -> TrackingStatus

If supported, returns the status of our tracking. This will allow you to provide feedback to the user whether there are issues with positional tracking.

pub fn get_render_target_size(&self) -> Vector2

Returns the resolution at which we should render our intermediate results before things like lens distortion are applied by the VR platform.

pub fn get_view_count(&self) -> u32

Returns the number of views that need to be rendered for this device. 1 for Monoscopic, 2 for Stereoscopic.

pub fn trigger_haptic_pulse( &mut self, action_name: impl AsArg<GString>, tracker_name: impl AsArg<StringName>, frequency: f64, amplitude: f64, duration_sec: f64, delay_sec: f64, )

Triggers a haptic pulse on a device associated with this interface.

action_name is the name of the action for this pulse.

tracker_name is optional and can be used to direct the pulse to a specific device provided that device is bound to this haptic.

frequency is the frequency of the pulse, set to 0.0 to have the system use a default frequency.

amplitude is the amplitude of the pulse between 0.0 and 1.0.

duration_sec is the duration of the pulse in seconds.

delay_sec is a delay in seconds before the pulse is given.

pub fn supports_play_area_mode(&mut self, mode: PlayAreaMode) -> bool

Call this to find out if a given play area mode is supported by this interface.

pub fn get_play_area_mode(&self) -> PlayAreaMode

pub fn set_play_area_mode(&mut self, mode: PlayAreaMode) -> bool

Sets the active play area mode, will return false if the mode can’t be used with this interface.

Note: Changing this after the interface has already been initialized can be jarring for the player, so it’s recommended to recenter on the HMD with center_on_hmd (if switching to PlayAreaMode::STAGE) or make the switch during a scene change.

pub fn get_play_area(&self) -> PackedArray<Vector3>

Returns an array of vectors that represent the physical play area mapped to the virtual space around the XROrigin3D point. The points form a convex polygon that can be used to react to or visualize the play area. This returns an empty array if this feature is not supported or if the information is not yet available.

pub fn get_anchor_detection_is_enabled(&self) -> bool

pub fn set_anchor_detection_is_enabled(&mut self, enable: bool)

pub fn get_camera_feed_id(&self) -> i32

If this is an AR interface that requires displaying a camera feed as the background, this method returns the feed ID in the CameraServer for this interface.

pub fn is_passthrough_supported(&self) -> bool

Returns true if this interface supports passthrough.

pub fn is_passthrough_enabled(&self) -> bool

Returns true if passthrough is enabled.

pub fn start_passthrough(&mut self) -> bool

Starts passthrough, will return false if passthrough couldn’t be started.

Note: The viewport used for XR must have a transparent background, otherwise passthrough may not properly render.

pub fn stop_passthrough(&mut self)

Stops passthrough.

pub fn get_transform_for_view( &self, view: u32, cam_transform: Transform3D, ) -> Transform3D

Returns the transform for a view/eye.

view is the view/eye index.

cam_transform is the transform that maps device coordinates to scene coordinates, typically the [member Node3D.global_transform] of the current XROrigin3D.

pub fn get_projection_for_view( &self, view: u32, aspect: f64, near: f64, far: f64, ) -> Projection

Returns the projection matrix for a view/eye.

pub fn get_supported_environment_blend_modes(&self) -> Array<Variant>

Returns the an array of supported environment blend modes, see [enum XRInterface.EnvironmentBlendMode].

pub fn set_environment_blend_mode(&mut self, mode: EnvironmentBlendMode) -> bool

Sets the active environment blend mode.

mode is the environment blend mode starting with the next frame.

Note: Not all runtimes support all environment blend modes, so it is important to check this at startup. For example:

func _ready():
	var xr_interface = XRServer.find_interface("OpenXR")
	if xr_interface and xr_interface.is_initialized():
		var vp = get_viewport()
		vp.use_xr = true
		var acceptable_modes = [XRInterface.XR_ENV_BLEND_MODE_OPAQUE, XRInterface.XR_ENV_BLEND_MODE_ADDITIVE]
		var modes = xr_interface.get_supported_environment_blend_modes()
		for mode in acceptable_modes:
			if mode in modes:
				xr_interface.set_environment_blend_mode(mode)
				break

pub fn get_environment_blend_mode(&self) -> EnvironmentBlendMode

pub fn get_class(&self) -> GString

Returns the object’s built-in class name, as a String. See also is_class.

Note: This method ignores class_name declarations. If this object’s script has defined a class_name, the base, built-in class name is returned instead.

pub fn is_class(&self, class: impl AsArg<GString>) -> bool

Returns true if the object inherits from the given class. See also get_class.

var sprite2d = Sprite2D.new()
sprite2d.is_class("Sprite2D") # Returns true
sprite2d.is_class("Node")     # Returns true
sprite2d.is_class("Node3D")   # Returns false

Note: This method ignores class_name declarations in the object’s script.

pub fn set(&mut self, property: impl AsArg<StringName>, value: &Variant)

Assigns value to the given property. If the property does not exist or the given value’s type doesn’t match, nothing happens.

var node = Node2D.new()
node.set("global_scale", Vector2(8, 2.5))
print(node.global_scale) # Prints (8.0, 2.5)

Note: In C#, property must be in snake_case when referring to built-in Godot properties. Prefer using the names exposed in the PropertyName class to avoid allocating a new StringName on each call.

pub fn get(&self, property: impl AsArg<StringName>) -> Variant

Returns the Variant value of the given property. If the property does not exist, this method returns null.

var node = Node2D.new()
node.rotation = 1.5
var a = node.get("rotation") # a is 1.5

Note: In C#, property must be in snake_case when referring to built-in Godot properties. Prefer using the names exposed in the PropertyName class to avoid allocating a new StringName on each call.

pub fn set_indexed( &mut self, property_path: impl AsArg<NodePath>, value: &Variant, )

Assigns a new value to the property identified by the property_path. The path should be a NodePath relative to this object, and can use the colon character (:) to access nested properties.

var node = Node2D.new()
node.set_indexed("position", Vector2(42, 0))
node.set_indexed("position:y", -10)
print(node.position) # Prints (42.0, -10.0)

Note: In C#, property_path must be in snake_case when referring to built-in Godot properties. Prefer using the names exposed in the PropertyName class to avoid allocating a new StringName on each call.

pub fn get_indexed(&self, property_path: impl AsArg<NodePath>) -> Variant

Gets the object’s property indexed by the given property_path. The path should be a NodePath relative to the current object and can use the colon character (:) to access nested properties.

Examples: "position:x" or "material:next_pass:blend_mode".

var node = Node2D.new()
node.position = Vector2(5, -10)
var a = node.get_indexed("position")   # a is Vector2(5, -10)
var b = node.get_indexed("position:y") # b is -10

Note: In C#, property_path must be in snake_case when referring to built-in Godot properties. Prefer using the names exposed in the PropertyName class to avoid allocating a new StringName on each call.

Note: This method does not support actual paths to nodes in the SceneTree, only sub-property paths. In the context of nodes, use get_node_and_resource instead.

pub fn get_property_list(&self) -> Array<Dictionary<Variant, Variant>>

Returns the object’s property list as an Array of dictionaries. Each Dictionary contains the following entries:

• name is the property’s name, as a String;

• class_name is an empty StringName, unless the property is VariantType::OBJECT and it inherits from a class;

• type is the property’s type, as an int (see [enum Variant.Type]);

• hint is how the property is meant to be edited (see [enum PropertyHint]);

• hint_string depends on the hint (see [enum PropertyHint]);

• usage is a combination of [enum PropertyUsageFlags].

Note: In GDScript, all class members are treated as properties. In C# and GDExtension, it may be necessary to explicitly mark class members as Godot properties using decorators or attributes.

pub fn get_method_list(&self) -> Array<Dictionary<Variant, Variant>>

Returns this object’s methods and their signatures as an Array of dictionaries. Each Dictionary contains the following entries:

• name is the name of the method, as a String;

• args is an Array of dictionaries representing the arguments;

• default_args is the default arguments as an Array of variants;

• flags is a combination of [enum MethodFlags];

• id is the method’s internal identifier int;

• return is the returned value, as a Dictionary;

Note: The dictionaries of args and return are formatted identically to the results of get_property_list, although not all entries are used.

pub fn property_can_revert(&self, property: impl AsArg<StringName>) -> bool

Returns true if the given property has a custom default value. Use property_get_revert to get the property’s default value.

Note: This method is used by the Inspector dock to display a revert icon. The object must implement [method _property_can_revert] to customize the default value. If [method _property_can_revert] is not implemented, this method returns false.

pub fn property_get_revert(&self, property: impl AsArg<StringName>) -> Variant

Returns the custom default value of the given property. Use property_can_revert to check if the property has a custom default value.

Note: This method is used by the Inspector dock to display a revert icon. The object must implement [method _property_get_revert] to customize the default value. If [method _property_get_revert] is not implemented, this method returns null.

pub fn set_meta(&mut self, name: impl AsArg<StringName>, value: &Variant)

Adds or changes the entry name inside the object’s metadata. The metadata value can be any Variant, although some types cannot be serialized correctly.

If value is null, the entry is removed. This is the equivalent of using remove_meta. See also has_meta and get_meta.

Note: A metadata’s name must be a valid identifier as per is_valid_identifier method.

Note: Metadata that has a name starting with an underscore (_) is considered editor-only. Editor-only metadata is not displayed in the Inspector and should not be edited, although it can still be found by this method.

pub fn remove_meta(&mut self, name: impl AsArg<StringName>)

Removes the given entry name from the object’s metadata. See also has_meta, get_meta and set_meta.

Note: A metadata’s name must be a valid identifier as per is_valid_identifier method.

Note: Metadata that has a name starting with an underscore (_) is considered editor-only. Editor-only metadata is not displayed in the Inspector and should not be edited, although it can still be found by this method.

pub fn get_meta(&self, name: impl AsArg<StringName>) -> Variant

To set the default parameters, use get_meta_ex and its builder methods. See the book for detailed usage instructions. Returns the object’s metadata value for the given entry name. If the entry does not exist, returns default. If default is null, an error is also generated.

Note: A metadata’s name must be a valid identifier as per is_valid_identifier method.

Note: Metadata that has a name starting with an underscore (_) is considered editor-only. Editor-only metadata is not displayed in the Inspector and should not be edited, although it can still be found by this method.

pub fn get_meta_ex<'ex>( &'ex self, name: impl AsArg<StringName> + 'ex, ) -> ExGetMeta<'ex>

Returns the object’s metadata value for the given entry name. If the entry does not exist, returns default. If default is null, an error is also generated.

Note: A metadata’s name must be a valid identifier as per is_valid_identifier method.

Note: Metadata that has a name starting with an underscore (_) is considered editor-only. Editor-only metadata is not displayed in the Inspector and should not be edited, although it can still be found by this method.

pub fn has_meta(&self, name: impl AsArg<StringName>) -> bool

Returns true if a metadata entry is found with the given name. See also get_meta, set_meta and remove_meta.

Note: A metadata’s name must be a valid identifier as per is_valid_identifier method.

pub fn get_meta_list(&self) -> Array<StringName>

Returns the object’s metadata entry names as an Array of StringNames.

pub fn add_user_signal(&mut self, signal: impl AsArg<GString>)

To set the default parameters, use add_user_signal_ex and its builder methods. See the book for detailed usage instructions. Adds a user-defined signal named signal. Optional arguments for the signal can be added as an Array of dictionaries, each defining a name String and a type int (see [enum Variant.Type]). See also has_user_signal and remove_user_signal.

add_user_signal("hurt", [
	{ "name": "damage", "type": TYPE_INT },
	{ "name": "source", "type": TYPE_OBJECT }
])

pub fn add_user_signal_ex<'ex>( &'ex mut self, signal: impl AsArg<GString> + 'ex, ) -> ExAddUserSignal<'ex>

Adds a user-defined signal named signal. Optional arguments for the signal can be added as an Array of dictionaries, each defining a name String and a type int (see [enum Variant.Type]). See also has_user_signal and remove_user_signal.

add_user_signal("hurt", [
	{ "name": "damage", "type": TYPE_INT },
	{ "name": "source", "type": TYPE_OBJECT }
])

pub fn has_user_signal(&self, signal: impl AsArg<StringName>) -> bool

Returns true if the given user-defined signal name exists. Only signals added with add_user_signal are included. See also remove_user_signal.

pub fn remove_user_signal(&mut self, signal: impl AsArg<StringName>)

Removes the given user signal signal from the object. See also add_user_signal and has_user_signal.

pub fn emit_signal( &mut self, signal: impl AsArg<StringName>, varargs: &[Variant], ) -> Error

Emits the given signal by name. The signal must exist, so it should be a built-in signal of this class or one of its inherited classes, or a user-defined signal (see add_user_signal). This method supports a variable number of arguments, so parameters can be passed as a comma separated list.

Returns Error::ERR_UNAVAILABLE if signal does not exist or the parameters are invalid.

emit_signal("hit", "sword", 100)
emit_signal("game_over")

Note: In C#, signal must be in snake_case when referring to built-in Godot signals. Prefer using the names exposed in the SignalName class to avoid allocating a new StringName on each call.

Panics

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will panic in such a case.

pub fn try_emit_signal( &mut self, signal: impl AsArg<StringName>, varargs: &[Variant], ) -> Result<Error, CallError>

Return type

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will return Err in such a case.

pub fn call( &mut self, method: impl AsArg<StringName>, varargs: &[Variant], ) -> Variant

Calls the method on the object and returns the result. This method supports a variable number of arguments, so parameters can be passed as a comma separated list.

var node = Node3D.new()
node.call("rotate", Vector3(1.0, 0.0, 0.0), 1.571)

Note: In C#, method must be in snake_case when referring to built-in Godot methods. Prefer using the names exposed in the MethodName class to avoid allocating a new StringName on each call.

Panics

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will panic in such a case.

pub fn try_call( &mut self, method: impl AsArg<StringName>, varargs: &[Variant], ) -> Result<Variant, CallError>

Return type

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will return Err in such a case.

pub fn call_deferred( &mut self, method: impl AsArg<StringName>, varargs: &[Variant], ) -> Variant

Calls the method on the object during idle time. Always returns null, not the method’s result.

Idle time happens mainly at the end of process and physics frames. In it, deferred calls will be run until there are none left, which means you can defer calls from other deferred calls and they’ll still be run in the current idle time cycle. This means you should not call a method deferred from itself (or from a method called by it), as this causes infinite recursion the same way as if you had called the method directly.

This method supports a variable number of arguments, so parameters can be passed as a comma separated list.

var node = Node3D.new()
node.call_deferred("rotate", Vector3(1.0, 0.0, 0.0), 1.571)

For methods that are deferred from the same thread, the order of execution at idle time is identical to the order in which call_deferred was called.

See also call_deferred.

Note: In C#, method must be in snake_case when referring to built-in Godot methods. Prefer using the names exposed in the MethodName class to avoid allocating a new StringName on each call.

Note: If you’re looking to delay the function call by a frame, refer to the SceneTree.process_frame and SceneTree.physics_frame signals.

var node = Node3D.new()
# Make a Callable and bind the arguments to the node's rotate() call.
var callable = node.rotate.bind(Vector3(1.0, 0.0, 0.0), 1.571)
# Connect the callable to the process_frame signal, so it gets called in the next process frame.
# CONNECT_ONE_SHOT makes sure it only gets called once instead of every frame.
get_tree().process_frame.connect(callable, CONNECT_ONE_SHOT)

Panics

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will panic in such a case.

pub fn try_call_deferred( &mut self, method: impl AsArg<StringName>, varargs: &[Variant], ) -> Result<Variant, CallError>

Return type

This is a varcall method, meaning parameters and return values are passed as Variant. It can detect call failures and will return Err in such a case.

pub fn set_deferred( &mut self, property: impl AsArg<StringName>, value: &Variant, )

Assigns value to the given property, at the end of the current frame. This is equivalent to calling set through call_deferred.

var node = Node2D.new()
add_child(node)

node.rotation = 1.5
node.set_deferred("rotation", 3.0)
print(node.rotation) # Prints 1.5

await get_tree().process_frame
print(node.rotation) # Prints 3.0

Note: In C#, property must be in snake_case when referring to built-in Godot properties. Prefer using the names exposed in the PropertyName class to avoid allocating a new StringName on each call.

pub fn callv( &mut self, method: impl AsArg<StringName>, arg_array: &AnyArray, ) -> Variant

Calls the method on the object and returns the result. Unlike call, this method expects all parameters to be contained inside arg_array.

var node = Node3D.new()
node.callv("rotate", [Vector3(1.0, 0.0, 0.0), 1.571])

Note: In C#, method must be in snake_case when referring to built-in Godot methods. Prefer using the names exposed in the MethodName class to avoid allocating a new StringName on each call.

If set to true, the object becomes unable to emit signals. As such, emit_signal and signal connections will not work, until it is set to false.

pub fn is_blocking_signals(&self) -> bool

Returns true if the object is blocking its signals from being emitted. See set_block_signals.

pub fn notify_property_list_changed(&mut self)

Emits the property_list_changed signal. This is mainly used to refresh the editor, so that the Inspector and editor plugins are properly updated.

pub fn set_message_translation(&mut self, enable: bool)

If set to true, allows the object to translate messages with tr and tr_n. Enabled by default. See also can_translate_messages.

pub fn can_translate_messages(&self) -> bool

Returns true if the object is allowed to translate messages with tr and tr_n. See also set_message_translation.

pub fn tr(&self, message: impl AsArg<StringName>) -> GString

To set the default parameters, use tr_ex and its builder methods. See the book for detailed usage instructions. Translates a message, using the translation catalogs configured in the Project Settings. Further context can be specified to help with the translation. Note that most Control nodes automatically translate their strings, so this method is mostly useful for formatted strings or custom drawn text.

If can_translate_messages is false, or no translation is available, this method returns the message without changes. See set_message_translation.

For detailed examples, see Internationalizing games.

Note: This method can’t be used without an Object instance, as it requires the can_translate_messages method. To translate strings in a static context, use translate.

pub fn tr_ex<'ex>(&'ex self, message: impl AsArg<StringName> + 'ex) -> ExTr<'ex>

Translates a message, using the translation catalogs configured in the Project Settings. Further context can be specified to help with the translation. Note that most Control nodes automatically translate their strings, so this method is mostly useful for formatted strings or custom drawn text.

If can_translate_messages is false, or no translation is available, this method returns the message without changes. See set_message_translation.

Note: This method can’t be used without an Object instance, as it requires the can_translate_messages method. To translate strings in a static context, use translate.

pub fn tr_n( &self, message: impl AsArg<StringName>, plural_message: impl AsArg<StringName>, n: i32, ) -> GString

To set the default parameters, use tr_n_ex and its builder methods. See the book for detailed usage instructions. Translates a message or plural_message, using the translation catalogs configured in the Project Settings. Further context can be specified to help with the translation.

If can_translate_messages is false, or no translation is available, this method returns message or plural_message, without changes. See set_message_translation.

The n is the number, or amount, of the message’s subject. It is used by the translation system to fetch the correct plural form for the current language.

For detailed examples, see Localization using gettext.

Note: Negative and float numbers may not properly apply to some countable subjects. It’s recommended to handle these cases with tr.

Note: This method can’t be used without an Object instance, as it requires the can_translate_messages method. To translate strings in a static context, use translate_plural.

pub fn tr_n_ex<'ex>( &'ex self, message: impl AsArg<StringName> + 'ex, plural_message: impl AsArg<StringName> + 'ex, n: i32, ) -> ExTrN<'ex>

Translates a message or plural_message, using the translation catalogs configured in the Project Settings. Further context can be specified to help with the translation.

If can_translate_messages is false, or no translation is available, this method returns message or plural_message, without changes. See set_message_translation.

pub fn get_translation_domain(&self) -> StringName

Returns the name of the translation domain used by tr and tr_n. See also TranslationServer.

pub fn set_translation_domain(&mut self, domain: impl AsArg<StringName>)

Sets the name of the translation domain used by tr and tr_n. See also TranslationServer.

pub fn is_queued_for_deletion(&self) -> bool

Returns true if the queue_free method was called for the object.

pub fn cancel_free(&mut self)

If this method is called during ObjectNotification::PREDELETE, this object will reject being freed and will remain allocated. This is mostly an internal function used for error handling to avoid the user from freeing objects when they are not intended to.

pub fn notify(&mut self, what: ObjectNotification)

⚠️ Sends a Godot notification to all classes inherited by the object.

Triggers calls to on_notification(), and depending on the notification, also to Godot’s lifecycle callbacks such as ready().

Starts from the highest ancestor (the Object class) and goes down the hierarchy. See also Godot docs for Object::notification().

Panics

If you call this method on a user-defined object while holding a GdRef or GdMut guard on the instance, you will encounter a panic. The reason is that the receiving virtual method on_notification() acquires a GdMut lock dynamically, which must be exclusive.

pub fn notify_reversed(&mut self, what: ObjectNotification)

⚠️ Like Self::notify(), but starts at the most-derived class and goes up the hierarchy.

See docs of that method, including the panics.
