Gravity (source code)

So here it is, with it's wonderful spanish comments :|.

As you could see, this code could and should be optimized to make it not so proccessor.intensive.

Anyway, it's a good example of how we can build our applications without referencing _root.

When the main class is initialized:

var miGravedad:Gravedad = new Gravedad(this);

A reference to the timeline where the main class is located is passed to the class constructor. So we avoid any future trouble.

So, download the source code (of course, if you wish to)
