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.
joy = vrjoystick(id,'forcefeedback') enables force feedback if the joystick supports this capability.
|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.|
