OpenXRExtensionWrapperExtension¶
Inherits: Object
Allows clients to implement OpenXR extensions with GDExtension.
Description¶
OpenXRExtensionWrapperExtension allows clients to implement OpenXR extensions with GDExtension. The extension should be registered with register_extension_wrapper.
Methods¶
Method Descriptions¶
Dictionary _get_requested_extensions ( ) virtual
Returns a Dictionary of OpenXR extensions related to this extension. The Dictionary should contain the name of the extension, mapped to a bool * cast to an integer:
If the
bool *is anullptrthis extension is mandatory.If the
bool *points to a boolean, the boolean will be updated totrueif the extension is enabled.
void _on_before_instance_created ( ) virtual
Called before the OpenXR instance is created.
bool _on_event_polled ( const void* event ) virtual
Called when there is an OpenXR event to process. When implementing, return true if the event was handled, return false otherwise.
void _on_instance_created ( int instance ) virtual
Called right after the OpenXR instance is created.
void _on_instance_destroyed ( ) virtual
Called right before the OpenXR instance is destroyed.
void _on_pre_render ( ) virtual
Called right before the XR viewports begin their rendering step.
void _on_process ( ) virtual
Called as part of the OpenXR process handling. This happens right before general and physics processing steps of the main loop. During this step controller data is queried and made available to game logic.
void _on_register_metadata ( ) virtual
Allows extensions to register additional controller metadata. This function is called even when the OpenXR API is not constructed as the metadata needs to be available to the editor.
Extensions should also provide metadata regardless of whether they are supported on the host system. The controller data is used to setup action maps for users who may have access to the relevant hardware.
void _on_session_created ( int session ) virtual
Called right after the OpenXR session is created.
void _on_session_destroyed ( ) virtual
Called right before the OpenXR session is destroyed.
void _on_state_exiting ( ) virtual
Called when the OpenXR session state is changed to exiting.
void _on_state_focused ( ) virtual
Called when the OpenXR session state is changed to focused. This state is the active state when the game runs.
void _on_state_idle ( ) virtual
Called when the OpenXR session state is changed to idle.
void _on_state_loss_pending ( ) virtual
Called when the OpenXR session state is changed to loss pending.
void _on_state_ready ( ) virtual
Called when the OpenXR session state is changed to ready. This means OpenXR is ready to set up the session.
void _on_state_stopping ( ) virtual
Called when the OpenXR session state is changed to stopping.
void _on_state_synchronized ( ) virtual
Called when the OpenXR session state is changed to synchronized. OpenXR also returns to this state when the application loses focus.
void _on_state_visible ( ) virtual
Called when the OpenXR session state is changed to visible. This means OpenXR is now ready to receive frames.
int _set_instance_create_info_and_get_next_pointer ( void* next_pointer ) virtual
Adds additional data structures when the OpenXR instance is created.
int _set_session_create_and_get_next_pointer ( void* next_pointer ) virtual
Adds additional data structures when the OpenXR session is created.
int _set_swapchain_create_info_and_get_next_pointer ( void* next_pointer ) virtual
Adds additional data structures when creating OpenXR swapchains.
int _set_system_properties_and_get_next_pointer ( void* next_pointer ) virtual
Adds additional data structures when interogating OpenXR system abilities.
OpenXRAPIExtension get_openxr_api ( )
Returns the created OpenXRAPIExtension, which can be used to access the OpenXR API.
void register_extension_wrapper ( )
Registers the extension. This should happen at core module initialization level.
