you’re limited to the "rectangle" defined by the
limits of the joystick. When the joystick returns
to its rest position, the value generated returns
to zero. When this is turned on, the joystick
represents a change in the c urrent position.
Moving the joystick forward, for example, can
cause an objec t to start moving, and it will
continue to move until you return the joystick to
its rest position.
Joystick Buttons group
Point-of-V iew Hat (Left-Ri ght, Up-Down)—The
Sidewinder includes a m ini-joystick on the tip
of the main joystick. Specify the direction this
joystick controls in the animation.
1, 2, 3, 4—Specifies one of four buttons in the
Sidewinder joystick. They work similarly to
the Point-of-View Hat, except that each button
increases a direct ion value only w h i le pressed.
When you release the button, the value returns to
zero (centered).
Inc./Dec.—One of three options available only when
you choose one of the numbered joystick button
options. This option (Increment/Decrement)
means that the value is i nc remented when the
button is down, and decremented w hen the button
is up.
Inc.—When turned on, the value increments w hen
the button is down, and stays at that value when
you release the button.
Absolute—When turned on, the assig ned
parameters jumps to the value set in the Speed
spinner when the button is down, and then jumps
back to zero w hen you release the button. Use this
for on/off animations, such as blinking lights.
Speed—Controls the rate at which the value
changes when using either the Point-of-View Hat
or the four buttons. When using a button option
and the Absolute option, this specifies the value
output when you press the button (Spinner Value:
float, -999,999 to 999,999).
Increment Based On Directio n group
Provides controls that let you derive the direction
of movement from a Rotation controller. These
options are used primarily when you’re animating
a first-person flythrough (such as when controlling
a camera).
Note: The items in this area are only available when
you select Accumulate in Joystick Axis.
Controller—Assigns a Rotation controller from
which the direction will be derived.
Cle ar —Removes the assigned controller.
Direction X/Y /Z—Specifies the local axis that will
be used as the direction. For a Free Camera, for
example, this would be Z because the camera
points in the Z direction. However, if yo u had a car
that pointed along its Y axis, you’d use Y.
Component X/Y/Z—Specifies the edit binding
to use. Match this to the Edit Binding button
under Device Bindings. For example, if the Y
