It may not do the same thing, but the tutorial itself teaches the method of easing using the easing equation. So everything you need to know is in there.

or on a frame…
[AS]targetClip.onEnterFrame = function(){
if (this.hitTest(\_root.\_xmouse, \_root.\_ymouse, true){
//ease to location onRollOver
} else {
//ease to location onRollOut (default location)
}
}[/AS]
You run the actions on enterFrame (basically constantly) and check if the mouse x and y position is over your clip, if it is, you ease it to the “out” position using the easing equation, else if it isn’t you ease it back to the original position using the easing equation.
Why hitTest()?
Simple… if you make the movie clip a button as sushis mentioned, you will not be able to have interactive content inside (ie: buttons, input text fields, sliders, or whatever else) because onRollOver converts it to sort of a button state, and you can’t have a button in a button because the main button will get the hit mouse state. hitTest() is a way to do onRollOver and onRollOut without using those actions so it doesn’t convert it to a button state.

Thanks for the info, Lost. That will be helpful on the site I’m building 🙂

No problem 🙂
hitTest is also used for other things (like in Flash games), but this seems to be one of the popular uses for it outside of game programming.
