The Time Slider is not involved in a driven key relationship and displays
no red markers for keys.
7 Move the ball to the doors position and then move the door above the
ball.
8 In the Set Driven Key window, click Key.
This sets another driven key that links the current Translate Z value of
the ball to the Translate Y value of the door.
9 Move the ball to the right of the door and then lower the door to its
previous position as shown in the following figure.
10 In the Set Driven Key window, click Key.
This sets another driven key that links the attributes.
Youve set three driven keys that link the attribute values at different
positions. Maya interpolates the linked values to generate the values
between the keys.
If you drag the ball toward the door from either side, the door rises
smoothly.
Playing back the animation from the Time Slider doesnt move the ball
or the door. Driven keys link one attribute to another. They dont link
attributes to times in the Time Slider. However, if you were to animate
the movement of the ball, the door would move based on the driven key
relationship that has been set.
