I’ve talked about the basics of Box2DFlash v1.4.3 in my Introductory tutorial. I showed how to create your world and how to introduce simple bodies into that world. With the release of Box2DFlash v2.0.0 the basics remain mostly the same, there are a few details changed. I need to go over these small changes before I move on to the next step of adding joints and forces to the bodies.
The first and biggest change (although really a small thing) is that we no longer work in pixels! We now work in units that by default equal 30 pixels to 1 unit (think of it as meters; 30px : 1m). With this change our normal gravity is no longer (0, 300) but instead (1, 10). This makes more sense to me at least because gravity in reality is 9.81 m/s/s. This is going to effect almost everything you do, from applying forces to setting the width and height of a box.

Creating an MP3 Player in ActionScript 3.0 is fairly straight forward. The complexity varies greatly depending on what kind of features you want your player to have. I don’t plan on getting into ID3 tags here, but otherwise (as you can see) I will be going over the full functionality of a normal MP3 Player. Read the rest of this entry »
In celebration of our little vector contest I thought I would unofficially submit my own entry.
I made this animation using our Spring Time vector pack. It’s about 360Kbs, but once it’s loaded click Play to get it started, then you can press the Left or Right arrows to control the little bunny.
I’ll walk you through the process I went through to create this here game/animation.
I wanted to try something fun with Flash this week, so I did a quick search for “Flash Physics Engine.” Lo and behold, I struck gold. Box2DFlashAS3 is an open source ActionScript 3.0 conversion of the C++ Physics Engine Box2D. I’m very impressed with its well coded structure and easily implemented nature. I learned a few new things that will change how I code forever just by reading through their example files.
Still, they have limited resources right now as far as help documentation goes (”Please refer to the source code from the examples provided to get an idea of how to use Box2DFlash in your projects.” — that’s the ReadMe.txt that comes with it… not very helpful,huh). I thought I might give you an example of my own and walk through it step by step. Read the rest of this entry »
I’m going to talk about how to build a simple 4 function calculator using static variables and meathods in Flash ActionScript 3.0. This is my first tutorial, so if you have questions or comments, I would appreciate them and will do what I can.
