Using preset eases
Easing can be very powerful and can be used to create many specialized motions.
For example, a bouncing motion can be created with just two positional keyframes
and an ease that moves the object back and forth between the two positions.
For the next example, you’ll return to the motion picture project and add a preset
ease to the motion of the car. You’ll make the car shudder up and down to mimic
the motion of an idling car. The motion tween will be created inside the movie clip
symbol of the car.
1 Continue with your Flash project in progress, 04_workingcopy.fla.
2 In the Library panel, double-click the movie clip symbol called carLeft.
Flash takes you to symbol-editing mode for the movie clip symbol. Two layers
are inside this symbol: the top layer called lights, and the bottom layer called
smallRumble.
3 Lock the top lights layer.
4 Right-click/Ctrl-click on the car and choose Create Motion Tween.
Flash converts the current layer to a Tween layer so you can begin to animate
the instance.
5 Move the red playhead to the end of the Timeline.
