A simple example of a tween would be to place a graphic at the top of the Stage and then add several frames to the Timeline and move the graphic to the bottom of the Stage in the last frame. By letting Flash fill in the position values for the frames in between, you can easily create a smooth animation of the graphic from the top of the Stage to the bottom. In this Flash project tutorial, designer David Stiller works with the new CS4 motion editor and its easing functions to adjust the speed of movement in a simple animation. The easing graphs allow for adjustments to motion speed to be made visually. Most sliding menu and sliding photos are created base on easing algorithm. If you want to learn basic flash easing, you can click here to launch the simple flash mx easing tutorial. Flash 8's new custom easing controls are located in the Custom Ease In / Ease Out dialog box. The 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 button for opening the box is located in the Frame Properties Inspector. A motion tween must be applied to the frame to make the button appear. |
