The 2nd tutorial, the 3rd in the book, involved creating animation using Actionscript and letting people control properties of objects like rotation and scale.
In addition to the tutorial I wanted to try and display a value of a property in a text box of one of the objects. I was able to get it to show the x position of the instrument selected on the screen, and will change whenever a different instrument is selected.
I feel that the animating and changing properties of an object would be the most useful in a game. While in a game something like scale wouldn’t be an option you could choose, but could be something that changes if you pick up a power-up.
I have uploaded the flash file here to show it working.
