OpenXRAPIExtension¶
Inherits: RefCounted < Object
Makes the OpenXR API available for GDExtension.
Description¶
OpenXRAPIExtension makes OpenXR available for GDExtension. It provides the OpenXR API to GDExtension through the get_instance_proc_addr method, and the OpenXR instance through get_instance.
It also provides methods for querying the status of OpenXR initialization, and helper methods for ease of use of the API with GDExtension.

Enumerations¶
enum OpenXRAlphaBlendModeSupport:
OpenXRAlphaBlendModeSupport OPENXR_ALPHA_BLEND_MODE_SUPPORT_NONE = 0
Means that XRInterface.XR_ENV_BLEND_MODE_ALPHA_BLEND isn't supported at all.
OpenXRAlphaBlendModeSupport OPENXR_ALPHA_BLEND_MODE_SUPPORT_REAL = 1
Means that XRInterface.XR_ENV_BLEND_MODE_ALPHA_BLEND is really supported.
OpenXRAlphaBlendModeSupport OPENXR_ALPHA_BLEND_MODE_SUPPORT_EMULATING = 2
Means that XRInterface.XR_ENV_BLEND_MODE_ALPHA_BLEND is emulated.
Method Descriptions¶
bool can_render()
Returns true
if OpenXR is initialized for rendering with an XR viewport.
String get_error_string(result: int)
Returns an error string for the given XrResult.
int get_hand_tracker(hand_index: int)
Returns the corresponding XRHandTrackerEXT
handle for the given hand index value.
int get_instance()
Returns the XrInstance created during the initialization of the OpenXR API.
int get_instance_proc_addr(name: String)
Returns the function pointer of the OpenXR function with the specified name, cast to an integer. If the function with the given name does not exist, the method returns 0
.
Note: openxr/util.h
contains utility macros for acquiring OpenXR functions, e.g. GDEXTENSION_INIT_XR_FUNC_V(xrCreateAction)
.
int get_next_frame_time()
Returns the timing for the next frame.
int get_play_space()
Returns the play space, which is an XrSpace cast to an integer.
int get_session()
Returns the OpenXR session, which is an XrSession cast to an integer.
String get_swapchain_format_name(swapchain_format: int)
Returns the name of the specified swapchain format.
int get_system_id()
Returns the id of the system, which is a XrSystemId cast to an integer.
OpenXRAlphaBlendModeSupport is_environment_blend_mode_alpha_supported()
Returns OpenXRAlphaBlendModeSupport denoting if XRInterface.XR_ENV_BLEND_MODE_ALPHA_BLEND is really supported, emulated or not supported at all.
bool is_initialized()
Returns true
if OpenXR is initialized.
bool is_running()
Returns true
if OpenXR is running (xrBeginSession was successfully called and the swapchains were created).
bool openxr_is_enabled(check_run_in_editor: bool) static
Returns true
if OpenXR is enabled.
void register_composition_layer_provider(extension: OpenXRExtensionWrapperExtension)
Registers the given extension as a composition layer provider.
void set_emulate_environment_blend_mode_alpha_blend(enabled: bool)
If set to true
, an OpenXR extension is loaded which is capable of emulating the XRInterface.XR_ENV_BLEND_MODE_ALPHA_BLEND blend mode.
Transform3D transform_from_pose(pose: const void*
)
Creates a Transform3D from an XrPosef.
void unregister_composition_layer_provider(extension: OpenXRExtensionWrapperExtension)
Unregisters the given extension as a composition layer provider.
bool xr_result(result: int, format: String, args: Array)
Returns true
if the provided XrResult (cast to an integer) is successful. Otherwise returns false
and prints the XrResult converted to a string, with the specified additional information.
