In this chapter, you were given a brief history of the methodologies of building user interfaces that send data to servers for processing and the constantly swinging pendulum from thin client to fat client. You were brought up-to-date on what the newest trend in this development is web-based thin clients with rich functionality thanks to the asynchrony delivered by the XMLHttpRequest object, which is the core of AJAX. You then built a simple example that demonstrated how it works. This example was very basic and barely scratched the surface of what can be done with AJAX. However, it demonstrated one of the drawbacks of using this methodology; namely, that it requires a lot of scripting. JavaScript, although powerful, is tedious to write and onerous to debug and manage when compared to languages such as C#, VB .NET, and Java. As such, the application benefits you receive by using an AJAX approach may be more than offset by the application development getting bogged down in thousands (or more) lines of JavaScript.

There are a couple ways to refine a shape tween once it s applied. These are shown in the Properties panel when you click in a tweened span of frames: Ease and Blend. Easing tends to make tweens look more lifelike because it gradually varies the amount of distance traveled between each frame. If an astronaut throws a golf ball in outer space, the ball flies at a constant rate until...well, until it hits something. That s not how it works on a planet with gravity. The ball flies faster at first and then gradually slows down. This deceleration is called easing out. A ball dropped from a tall building begins its descent slowly and then gradually increases speed. This acceleration is called easing in. Click anywhere between two key frames of a tween, and adjust the Ease hot text in the Properties panel to see how easing affects the shape tween applied to the pepper in the previous exercise. Supported values range from 100 (strong ease out), through 0 (no easing), to 100 (strong ease in). As shown in Figure 7-6, easing can have a profound effect upon an object in motion. We ll cover easing in greater detail in the Classic tweening section.

In the next example, we search for node2 and insert a new entry prior to the line that is found. There are three commands:

If you don t see much of a difference after experimenting with easing, try lengthening the duration of your shape tween. To do so, click somewhere in the tween span between the two keyframes, and then press the F5 key several times to insert new frames.
