Last weekend I had some spare time for writing an article I got in mind from long time ago, this is about Elastic Collisions, pretty much simple concept but apparently there are some people implementing it in the wrong way (I heard about some crazy exceptions, many bugs and problems people have) and in most of these cases it is because of they are detecting collisions in a wrong workflow. When we speak about elastic collisions we are speaking about the response of it after the collision happens and not when it actually happens (its detection), you must be careful in the way how you detect when the collisions occur, one think is detecting when the collision happens and other completely different is what happen after it.

The first time I heard about Verlets was about 10 years ago I think, when I was working on a C++ program building a dynamic animated bridge, at that time all documents and resources I found about Verlets were really confusing and at the end I gave up on it (sometimes people explain things in the most complicated way). Last year 2009 in flash on the beach (Brighton, UK) when I was attending the session of Keith Peters, he came with some really good ideas about how to implement the “Verlet Integration” in flash using actionscript 3 in a very, very easy way that makes my imagination flights.

its useful for other stuff too By Joran420

This tutorial illustrates how to trace curves like a cardioid. The process can be extended to trace other interesting shapes. By williama

This is GinjaNinja's bouncing ball tutorial converted into actionscript v2. By phantz

Two for the price of none. Haven't seen too many tutorials on this kind of stuff so here you go. By miscellaneum

This tutorial will show you a neat bouncing ball with trails. This also demonstrates the nice application of physics. By Williama

The shortest gravity engine I could think of! By GinjaNinja

Convert standard timing format (hh.mm.ss) to internet timing format (@123). By Ash Sammy

In this tutorial you will learn how to sort a set of numbers in an array from least to greatest. This can be useful for card games or for statistical problems. By Andross

A calculator designed especially for summing out the price of a car. By Ash Sammy

This is a short script that can be used to make a movieclip rotate in the direction of another object, such as the mouse. By Jim Bumgardner
