X, Y, Z—Specifies which joystick direction drives
the animation. (Standard joysticks provide X and
Y axes on ly. The Sidewinder provides the Z axis
when you tw ist the joystick.)
Throttle—On the Sidewinder, this is a slider next
to the stick.
Scale—Scalestherelativeeffectofthejoystick
action to the animation response. Spinner
Value=float, 0 to 999,999
Flip—Flips the direction of the response.
Accumulat e—When off, the joystick position
represents an absolute position, and 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 on, the joystick represents a change in the
current position. Moving the joystick forward,
for example, can cause an object to start moving,
and it will continue to move until you return the
joystick to its rest position.
Joystick Buttons group
Point-of -V i ew Ha t ( Lef t-R i ght, Up-Down)—Amini
joystick on the tip of the main joystick that
specifies the direction of 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 direction va lue only while pressed.
When you release the button, the value returns to
zero (centered).
Inc./Dec—One of three options that are only
availablewhenoneofthenumberedjoystick
button options is turned on. This option
(Increment/Decrement) means that the value
is incremented when the button is down, and
decremented when the button is up.
Inc—When on, the value increments when the
buttonisdown,andstaysatthatvaluewhenthe
button is released.
Absolute—When on, the assig ned parameters
jumps to t he value set in the Speed spinner w hen
thebuttonisdown,andthenjumpsbacktozero
when the button is released. 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
orthefourbuttons.Whenusingabuttonoption
and the Absolute option, this specifies the value
that’s output when the button is pressed. Spinner
Value=float, -999,999 to 999,999
Increment B ased On Direction g roup
This 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
you’re controlling a camera.
