OpenXRInterface

Inherits: XRInterface < RefCounted < Object

Our OpenXR interface.

Description

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.

Property Descriptions

float display_refresh_rate = 0.0

  • void set_display_refresh_rate ( float value )

  • float get_display_refresh_rate ( )

The display refresh rate for the current HMD. Only functional if this feature is supported by the OpenXR runtime and after the interface has been initialized.


float render_target_size_multiplier = 1.0

  • void set_render_target_size_multiplier ( float value )

  • float get_render_target_size_multiplier ( )

The render size multiplier for the current HMD. Must be set before the interface has been initialized.


Method Descriptions

Array get_action_sets ( ) const

Returns a list of action sets registered with Godot (loaded from the action map at runtime).


Array get_available_display_refresh_rates ( ) const

Returns display refresh rates supported by the current HMD. Only returned if this feature is supported by the OpenXR runtime and after the interface has been initialized.


Vector3 get_hand_joint_angular_velocity ( Hand hand, HandJoints joint ) const

If handtracking is enabled, returns the angular velocity of a joint (joint) of a hand (hand) as provided by OpenXR. This is relative to XROrigin3D!


Vector3 get_hand_joint_linear_velocity ( Hand hand, HandJoints joint ) const

If handtracking is enabled, returns the linear velocity of a joint (joint) of a hand (hand) as provided by OpenXR. This is relative to XROrigin3D without worldscale applied!


Vector3 get_hand_joint_position ( Hand hand, HandJoints joint ) const

If handtracking is enabled, returns the position of a joint (joint) of a hand (hand) as provided by OpenXR. This is relative to XROrigin3D without worldscale applied!


float get_hand_joint_radius ( Hand hand, HandJoints joint ) const

If handtracking is enabled, returns the radius of a joint (joint) of a hand (hand) as provided by OpenXR. This is without worldscale applied!


Quaternion get_hand_joint_rotation ( Hand hand, HandJoints joint ) const

If handtracking is enabled, returns the rotation of a joint (joint) of a hand (hand) as provided by OpenXR.


HandMotionRange get_motion_range ( Hand hand ) const

If handtracking is enabled and motion range is supported, gets the currently configured motion range for hand.


bool is_action_set_active ( String name ) const

Returns true if the given action set is active.


void set_action_set_active ( String name, bool active )

Sets the given action set as active or inactive.


void set_motion_range ( Hand hand, HandMotionRange motion_range )

If handtracking is enabled and motion range is supported, sets the currently configured motion range for hand to motion_range.
