This creates a new keyframe and records the new location. Repeat this step to create additional keyframes.
6
To make the property changes defined by a keyframe occur at a different time, drag the keyframe in the Score to
a new frame within the sprite.
7
To change the degree of curvature between keyframes, select Modify > Sprite > Tweening and adjust the
Curvature slider. To make the sprite move in the same direction at the beginning and end, select Continuous At
Endpoints in the Sprite Tweening dialog box. This creates a circular motion. For more information, see

tweening settings
.
Accelerating and decelerating sprites
To create more natural motion in tweened sprites, use the following settings in the Sprite Tweening dialog box:
•
Ease-In and Ease-Out control how a sprite moves from its start frame to its end frame, regardless of how many
keyframes are in between. Ease-In makes a sprite move more slowly in the beginning frames. Ease-Out makes the
sprite slow down in the ending frames. This setting makes the sprite move more like an object in the real world.
•
The Speed settings control how Director moves a sprite between each keyframe. The Sharp Changes option is
the default setting. Using this option, Director calculates how to move the sprite between each pair of keyframes
separately. If a sprite’s keyframes are separated by unequal numbers of frames in the Score, or by different amounts
of space on the Stage, abrupt changes in speed might occur as the sprite moves between keyframe locations. Smooth
out these speed changes by selecting the Smooth Changes option.
Sprite with modified ease-in and ease-out settings
1
Use one of the tweening methods to create a moving sprite.
2
Select View > Sprite Overlay > Show Paths to see how far the sprite moves between each frame.
3
Select the sprite and select Modify > Sprite > Tweening.
4
Use the Ease-In and Ease-Out sliders to specify the percentage of the sprite’s path through which the sprite
should accelerate or decelerate.
5
Select a speed setting:
Sharp Changes
moves the sprite between keyframe locations without adjusting the speed.
Smooth Changes
adjusts the sprite’s speed gradually as it moves between keyframes.
Tweening other sprite properties
In addition to tweening a sprite’s path, Director can tween the size, rotation, skew, blend, and foreground and
background color of a sprite. Tweening size works best for vector-based cast members created in the Vector Shape
window or in Adobe
®
Flash
®
(bitmaps can become distorted when resized). Director can tween all of these
properties at once.
To make a sprite fade in or out, tween blend settings. To make sprites spin or tilt, use rotation. To create gradual shifts
in color, you can tween color settings.
