Managing Menu Buttons in Actionscript 3

June 18, 2009

One very common task in creating Flash applications is managing menu buttons. It tends to be a very repetitive business. The best approach would be to create a component with a label that you can change at runtime. But in order to create such a component first you need to understand how Flash UI Components work, and that’s not easy. But there are other, simpler approaches that you can use.

Actionscript Physics Engine

May 21, 2009

APE stands for Actionscript Physics Engine and it´s a great engine that allows for easy creation of dynamic systems that simulate physics. You start by creating particles and groups of particles, apply forces (such as gravity) and constraints (such as spring) to these particles and groups and add listeners to detect collisions beetween them.

The engine is in a very mature state and in constant development. And it’s open-source.

Flash Frameworks are a big thing nowadays. They make the job of creating a Flash-based web site easier, help you organize your code and files. There are many of these in development out there, but Gaia Flash Framework is one that stands out in the crowd.

Apart from it’s intuitive work-flow and beying open-source, what makes it so great is that it integrates into Flash CS3/CS4, providing an user interface that makes the creation of web sites as easy as pushing a few buttons.

Other features like deep-site-linking, timeline or actionscript based transitions, actionscript 2 and 3 support and scafolding complete the package.

CompositePost WordPress Plugin

February 9, 2009

This is a rewrite of a plugin I wrote some time ago.

It let’s you write posts and pages composed of other posts and pages.



Write anywhere on a post:

[composite option=”value”]

You can specify one or more options. The options are the same used in the get_posts() function (see


Show all posts from category Projects and include post with ID = 1:

[composite category_name=”Projects” include=”1″]


CompositePost create a loop using a template located in the plugin’s folder (usually /wordpress/wp-content/plugins/composite_post). The default template is /wordpress/wp-content/plugins/compositepost/default.php. You can have as many templates as you want, just specify wich one to use, like this:

[composite category_name=”Projects” template=”my_template”]

CompositePost will look for the file at /wordpress/wp-content/plugins/compositepost/my_template.php

Layout Manager

February 2, 2009

Ever since Flex came out people have been after similar functionality for Flash. There aren’t many options out there, but a few worth mentioning are and After studying these (great) diferent approaches, I decided to give it a try and build my own version, similarities not a coincidence.

LayoutManager and LayoutElement

LayoutElement extends a DisplayObject’s size and positioning properties. Both size and position can be specified in pixels or percentage of a container. LayoutManager manages LayoutElements and updates them as necessary.

LayoutManager Demo


LayoutContainer extends Flash’s UIComponent and works much like ScrollPane, except it’s content can be added/removed directly just like any other DisplayObjectContainer.

Layout Containers

Layouts Containers, such as Canvas, HBox and VBox, extends from the LayoutContainer class and add LayoutManager and LayoutElement functionality.
