Chapter 5 Using Behaviors 345
The Fade In/Fade Out behavior is useful for introducing and removing images you’re
animating in the middle of a project. For example, you could apply the Fade In/Fade
Out behavior to text objects moving slowly across the screen to make them fade into
existence, and then fade away at the end of their duration.
Dashboard control
The Dashboard lets you control the Fade In and Fade Out durations, equivalent to the
Fade In Time and Fade Out Time parameters in the Behaviors tab of the Inspector. Drag
anywhere within the shaded area of the Fade In or the Fade Out ramp to adjust their
durations.
Note: You can extend the durations of the Fade In or Fade Out past the limits of the
graphical Dashboard control.
Parameters in the Inspector
Fade In Time: A slider defining the duration, in frames, over which the object fades in
from 0 to 100 percent opacity from the first frame of the object. A duration of 0 frames
results in a straight cut into the object, making it appear instantly.
Fade Out Time: A slider defining the duration, in frames, over which the object fades
out from 100 to 0 percent opacity from the last frame of the object. A duration of 0
frames results in a straight cut away from the object, making it disappear instantly.
Start Offset: A slider that lets you delay the beginning of the behavior’s effect relative
to the first frame of its position in the Timeline. Adjust this parameter to make the
behavior start later. This parameter value is measured in frames.
End Offset: A slider that lets you offset the end of the behavior’s effect relative to the
last frame of its position in the Timeline, in frames. Adjust this parameter to make the
behavior stop before the actual end of the behavior in the Timeline. Use this slider to
offset the end of the Fade Out effect from the end of the object.
