Function Documentation

◆ qwerty_add_look_delta()

void qwerty_add_look_delta	(	struct qwerty_device *	qd,
		float	yaw,
		float	pitch
	)

Add yaw and pitch movement for the next frame.

References qwerty_device::look_speed, qwerty_device::pitch_delta, and qwerty_device::yaw_delta.

◆ qwerty_change_movement_speed()

void qwerty_change_movement_speed	(	struct qwerty_device *	qd,
		float	steps
	)

Change movement speed in exponential steps (usually integers, but any float allowed)

References qwerty_device::movement_speed.

◆ qwerty_controller()

struct qwerty_controller * qwerty_controller ( struct xrt_device * xd )

Cast to qwerty_controller.

Ensures returning a valid controller or crashing.

◆ qwerty_controller_create()

struct qwerty_controller * qwerty_controller_create	(	bool	is_left,
		struct qwerty_hmd *	qhmd
	)

Create qwerty_controller.

Crash on failure.

◆ qwerty_create_devices()

xrt_result_t qwerty_create_devices	(	enum u_logging_level	log_level,
		struct xrt_device **	out_hmd,
		struct xrt_device **	out_left,
		struct xrt_device **	out_right
	)

#include <drivers/qwerty/qwerty_interface.h>

Create all qwerty devices.

◆ qwerty_device()

struct qwerty_device * qwerty_device ( struct xrt_device * xd )

Cast to qwerty_device.

Ensures returning a valid device or crashing.

◆ qwerty_follow_hmd()

void qwerty_follow_hmd	(	struct qwerty_controller *	qc,
		bool	follow
	)

Attach/detach the pose of qc to its HMD.

Only works when a qwerty_hmd is present.

◆ qwerty_hmd()

struct qwerty_hmd * qwerty_hmd ( struct xrt_device * xd )

Cast to qwerty_hmd.

Ensures returning a valid HMD or crashing.

◆ qwerty_hmd_create()

struct qwerty_hmd * qwerty_hmd_create ( void )

Create qwerty_hmd.

Crash on failure.

◆ qwerty_press_menu()

void qwerty_press_menu ( struct qwerty_controller * qc )

Simulate pressing input/menu/click.

References os_monotonic_get_ns().

◆ qwerty_press_sprint()

void qwerty_press_sprint ( struct qwerty_device * qd )

Momentarily increase movement_speed until qwerty_release_sprint()

References qwerty_device::sprint_pressed.

◆ qwerty_press_squeeze()

void qwerty_press_squeeze ( struct qwerty_controller * qc )

Simulate pressing input/squeeze/click.

References os_monotonic_get_ns().

◆ qwerty_press_system()

void qwerty_press_system ( struct qwerty_controller * qc )

Simulate pressing input/system/click.

References os_monotonic_get_ns().

◆ qwerty_press_trigger()

void qwerty_press_trigger ( struct qwerty_controller * qc )

Simulate pressing input/trigger/value to 1.0.

References os_monotonic_get_ns().

◆ qwerty_process_event()

void qwerty_process_event	(	struct xrt_device **	xdevs,
		size_t	xdev_count,
		SDL_Event	event
	)

#include <drivers/qwerty/qwerty_interface.h>

Process an SDL_Event (like a key press) and dispatches a suitable action to the appropriate qwerty_device.

Note: A qwerty_controller might not be in use (for example if you have physical controllers connected), though its memory will be modified by these events regardless. A qwerty_hmd not in use will not be modified as it never gets created.

◆ qwerty_release_all()

void qwerty_release_all ( struct qwerty_device * qd )

Release all movement input.

References qwerty_device::pitch_delta, qwerty_device::sprint_pressed, and qwerty_device::yaw_delta.

◆ qwerty_release_menu()

void qwerty_release_menu ( struct qwerty_controller * qc )

Simulate releasing input/menu/click.

References os_monotonic_get_ns().

◆ qwerty_release_sprint()

void qwerty_release_sprint ( struct qwerty_device * qd )

Stop doing what qwerty_press_sprint started.

References qwerty_device::sprint_pressed.

◆ qwerty_release_squeeze()

void qwerty_release_squeeze ( struct qwerty_controller * qc )

Simulate releasing input/squeeze/click.

References os_monotonic_get_ns().

◆ qwerty_release_system()

void qwerty_release_system ( struct qwerty_controller * qc )

Simulate releasing input/system/click.

References os_monotonic_get_ns().

◆ qwerty_release_trigger()

void qwerty_release_trigger ( struct qwerty_controller * qc )

Simulate releasing input/trigger/value to 0.0.

References os_monotonic_get_ns().

◆ qwerty_reset_controller_pose()

void qwerty_reset_controller_pose ( struct qwerty_controller * qc )

Reset controller to initial pose and makes it follow the HMD.

References qwerty_system::hmd, and qwerty_device::sys.
