1. | In the Timeline, select the entire Ball layer. |
2. | In the Property inspector, click Edit next to the Ease slider.  The Custom Ease In / Ease Out dialog box displays a graph representing the degree of motion over time. Frames are represented by the horizontal axis, and the percentage of change is represented by the vertical axis.The Custom Ease In / Ease Out dialog box  |
3. | In the Custom Ease In / Ease Out dialog box, Control-click (Windows) or Command-click (Macintosh) on the diagonal line where it crosses Frame 20 in the horizontal axis and on about 32% in the vertical axis. Click just once. This adds a new control point to the line. Clicking the Ease In / Ease Out diagonal line  |
4. | Drag the line to the top of the graph (the 100% line) while keeping it at Frame 20 on the horizontal axis. The line is now a complex curve. Dragging the control point to the top of the graph  |
5. | Drag the left vertex handle of the new control point to the right until it touches the control point. Drag the right vertex handle to the left until it touches the control point. This makes the curve pass through the control point with a simple sharp angle. The control point with the vertex handles dragged onto the point  |
6. | Control-click (Windows) or Command-click (Macintosh) the flat part of the curve at the top of the graph near Frame 32 and drag the new point downward to approximately 76% along the vertical axis. Dragging the point at Frame 32  |
7. | Drag the vertex handles so that the line connecting them to the control point is horizontal and each handle is the same distance from the control point. Dragging the vertex handles  |
8. | Control-click (Windows) or Command-click (Macintosh) the curve at about Frame 44 and drag it up to the 100% line. |
9. | Drag the vertex handles for the new control point onto the control point. |
10. | Control-click (Windows) or Command-click (Macintosh) the curve at about Frame 52 and drag it down to about 95% on the vertical axis. |
11. | Drag the vertex handles so that the line connecting them to the control point is horizontal and each handle is the same distance from the control point. The completed Ease In / Ease Out curve  You have now created a complex easing curve that represents a bouncing eight ball instead of a simple one-way motion tween. You can use the Play button in the Custom Ease In / Ease Out dialog box to preview your animation on the Stage while you experiment with the tween curve. |
12. | In the lower-left corner of the Custom Ease In / Ease Out dialog box, click Play. Review the live preview of your animation on the Stage. |
13. | Click OK to close the dialog box. |
14. | Select File > Save to save your FLA file. |
