Setting Things Up

As far as graphics go, all you need are six buttons of different colors, and one circle graphic that will serve as the drop target (about the same size as the buttons). Convert each of the buttons to a movie clip so you will be able to drag them and you are good to go. In my movie, I have a few extra graphics used to snazz up the buttons a bit, but it is unnecessary. Set up your layers as shown below.

The stayers layer contains one instance of each of the six movie clips, with instance names balla1 to balla6. The draggers layer contains the same as the stayers layer except the instance names are ball1 to ball6. In my movie I have grouped each set of movie clips in these two layers off the stage. They will be placed on stage by the code at run-time. The targets layer contains six instances of the target graphic, arranged however you want on the stage, with instance names target1 to target6. The code layer contains the initialization code that runs first time the movie is run, as well as an instance of a code movie clip, with the instance named, surprisingly enough, code. Here is the layout for the code movie clip.
