positions of the control points.
Using frame indicators (represented by square handles), click where you want an object to slow down or speed up. Clicking the square handle of a
control point selects that control point, and displays the tangent points on either side of it. Hollow circles represent tangent points. Drag the control
point or its tangent points with the mouse or use the keyboard’s arrow keys to position them.
By default, the control points snap to a grid. You can turn off snapping by pressing the X key while dragging the control point.
Clicking an area of the curve away from any control points adds a new control point to the curve at that point, without changing the shape of the
curve. Clicking away from the curve and control points deselects the currently selected control point.
Add a custom ease
1. Select a layer in the Timeline that has a
to it.
2. Click the Edit button next to the Ease slider in the frame Property inspector.
3. (Optional) To display the curve for a single tweened property, deselect Use One Setting For All Properties, and select a property in the
menu.
4. To add a control point, Control-click (Windows) or Command-click (Macintosh) the diagonal line.
5. To increase the speed of the object, drag the control point up; to slow down the speed of the object, drag it downwards.
6. To further adjust the ease curve, and fine tune the ease value of the tween, drag the vertex handles.
7. To view the animation on the Stage, click the play button in the lower-left corner.
8. Adjust the controls until you achieve the desired effect.
Note: If you use the Custom Ease In/Ease Out dialog box to apply a custom ease to a frame, the edit box that shows the ease value shows '--'. If
you use the Edit box or the pop-up slider to apply an ease value to a frame, the Custom Ease graph is set to the equivalent curve, and the Use
One Setting For All Properties check box is selected.
Copy and paste an ease curve
To copy the current ease curve, press Control+C (Windows) or Command+C (Macintosh).
To paste the copied curve into another ease curve, press Control+V (Windows) or Command+V (Macintosh).
You can copy and paste the ease curve. The copied curve remains available until you exit the Flash Professional application.
Unsupported easing curves
Certain types of easing curves are not supported. No part of the graph can represent a nonlinear curve (such as a circle).
The Custom Ease dialog box automatically prevents moving a control point or a tangent handle to a position that would render an invalid curve:
All points must exist on the graph. Control points cannot be moved beyond the bounds of the graph.
All segments of the curve must exist within the graph. The shape of the curve is flattened to prevent it from extending beyond the bounds of
the graph.
