Timelines and Animation
Apply custom ease in/ease out to classic tweens
The Custom Ease In/Ease Out dialog box displays a graph representing the degree of motion over time. The horizontal
axis represents frames, and the vertical axis represents percentage of change. The first keyframe is represented as 0%,
and the last keyframe is represented as 100%.
The slope of the graph’s curve represents the rate of change of the object. When the curve is horizontal (no slope), the
velocity is zero; when the curve is vertical, an instantaneous rate of change occurs.
Custom Ease In/Ease Out graph showing constant velocity
Additional controls for the Custom Ease In/Ease Out dialog box
Use One Setting For All Properties check box
The default is selected; the displayed curve is used for all properties, and
the Properties pop-up menu is disabled. When the check box is not selected, the Properties pop-up menu is enabled,
and each property has a separate curve defining the velocity of that property.
Property pop-up menu
Enabled only when the Use One Setting for All Properties check box is not selected. When
enabled, a separate curve is maintained for each of the five properties appearing in the menu. Selecting a property in
the menu displays the curve for that property. The properties are:
Position
Specifies custom ease settings for the position of an animated object on the Stage.
Rotation
Specifies custom ease settings for the rotation of an animated object. For example, you can fine-tune how
quickly or slowly an animated character turns around to face the user on the Stage.
Scale
Specifies custom ease settings for the scale of an animated object. For example, you can more easily customize
the scale of an object so it appears to be moving away from the viewer, then coming closer, and then moving away
again.
Color
Specifies custom ease settings for color transitions applied to an animated object.
Filters
Specifies custom ease settings for filters applied to an animated object. For example, you can control the ease
setting of a drop shadow that simulates a change in the direction of a light source.
Play and Stop buttons
Let you preview an animation on the Stage using all the current velocity curves defined in the
Custom Ease In/Ease Out dialog box.
Reset button
Lets you reset the velocity curve to the default, linear state.
