Downloading and installing Box2D for
Flash
You can download the latest version of Box2D for Flash either from the official site
(
http://www.box2dflash.org/download
) or from the SourceForge project page
(
http://sourceforge.net/projects/box2dflash/
).
Once you have downloaded the zipped package, extract the
Box2D
folder (you can find
it inside the
Source
folder) into the same folder you are using for your project. The
following is how your awesome game folder should look before you start coding:
You can see the
Box2D
folder, the FLA file that I am assuming has a document class
called
Main
and therefore
Main.as
, which is the class we will work on.
I would suggest you work on a 640 x 480 Flash movie at 30
frames per second
(
fps
). The document class should be called
Main
and the examples will look better
if you use a dark stage background color, such as
#333333
. At least these are the
settings I am using throughout the topic. Obviously you can change them as you
want, but in that case your final movies may look a bit different than the examples
shown in the topic.
Now let's import Box2D classes.
Hello Box2D World
Box2D is free and open source, so you won't need to install components or deal
with SWC files. All you need to do to include it in your projects is to include the
required classes.
