Create joystick object
joy = vrjoystick(id) joy = vrjoystick(id,'forcefeedback')
joy = vrjoystick(id) creates a joystick object capable of
interfacing with a joystick device. The id parameter is a one-based
joystick ID. The joystick ID is the system ID assigned to the given joystick device. You can
find the properties of the joystick that is connected to the system in the Game Controllers
section of the system Control Panel.
joy = vrjoystick(id,'forcefeedback') enables force feedback if the
joystick supports this capability.
| Method | Description |
|---|---|
axis |
a = axis(joy, n)reads the status of joystick with axis number
n. Axis status is returned in the range of -1 to 1. The
n parameter may be a vector to return multiple buttons. |
button | b = button(joy, n) reads the status of joystick button
number n. Button status is returned as logical 0 if not pressed
and logical 1 if pressed. The n parameter may be a vector to
return multiple buttons. |
caps | c = caps(joy) returns joystick capabilities, such as the
number of axes, buttons, POVs, and force-feedback axes. The return value is a
structure with fields named Axes, Buttons,
POVs, and Forces. |
close | close(joy) closes and invalidates the joystick object. The
object cannot be used once it is closed. |
force | force(joy, n, f) applies force feedback to joystick axis
n. The n parameter can be a vector to affect
multiple axes. f values should be in range of -1 to 1, and the
number of elements in f should either match the number of
elements of n, or f can be a scalar to be
applied to all the axes specified by n. |
pov | p = pov(joy, n) reads the status of joystick POV (point of
view) of control number n. pov is usually
returned in degrees, with -1 meaning "not selected." n can be a
vector to return multiple POVs. |
read | [axes, buttons, povs] = read(joy) reads the status of axes,
buttons, and POVs of the specified joystick. [axes, buttons, povs] =
read(joy, forces) applies feedback forces, in addition, to a
force-feedback joystick. |
