OpenXRInteractionProfileMetadata

Inherits: Object

Meta class registering supported devices in OpenXR.

Description

This class allows OpenXR core and extensions to register metadata relating to supported interaction devices such as controllers, trackers, haptic devices, etc. It is primarily used by the action map editor and to sanitize any action map by removing extension-dependent entries when applicable.

Methods

void	register_interaction_profile ( String display_name, String openxr_path, String openxr_extension_name )
void	register_io_path ( String interaction_profile, String display_name, String toplevel_path, String openxr_path, String openxr_extension_name, ActionType action_type )
void	register_profile_rename ( String old_name, String new_name )
void	register_top_level_path ( String display_name, String openxr_path, String openxr_extension_name )

Method Descriptions

void register_interaction_profile ( String display_name, String openxr_path, String openxr_extension_name )

Registers an interaction profile using its OpenXR designation (e.g. /interaction_profiles/khr/simple_controller is the profile for OpenXR's simple controller profile).

display_name is the description shown to the user. openxr_path is the interaction profile path being registered. openxr_extension_name optionally restricts this profile to the given extension being enabled/available. If the extension is not available, the profile and all related entries used in an action map are filtered out.

---

void register_io_path ( String interaction_profile, String display_name, String toplevel_path, String openxr_path, String openxr_extension_name, ActionType action_type )

Registers an input/output path for the given interaction_profile. The profile should previously have been registered using register_interaction_profile. display_name is the description shown to the user. toplevel_path specifies the bind path this input/output can be bound to (e.g. /user/hand/left or /user/hand/right). openxr_path is the action input/output being registered (e.g. /user/hand/left/input/aim/pose). openxr_extension_name restricts this input/output to an enabled/available extension, this doesn't need to repeat the extension on the profile but relates to overlapping extension (e.g. XR_EXT_palm_pose that introduces …/input/palm_ext/pose input paths). action_type defines the type of input or output provided by OpenXR.

---

void register_profile_rename ( String old_name, String new_name )

Allows for renaming old interaction profile paths to new paths to maintain backwards compatibility with older action maps.

---

void register_top_level_path ( String display_name, String openxr_path, String openxr_extension_name )

Registers a top level path to which profiles can be bound. For instance /user/hand/left refers to the bind point for the player's left hand. Extensions can register additional top level paths, for instance a haptic vest extension might register /user/body/vest.

display_name is the name shown to the user. openxr_path is the top level path being registered. openxr_extension_name is optional and ensures the top level path is only used if the specified extension is available/enabled.

When a top level path ends up being bound by OpenXR, a XRPositionalTracker is instantiated to manage the state of the device.
