How to correct 3-D projection on stage resize

The problem:
You’re using Flash 10’s native 3-D API and notice the projection goes a little skewiff when resizing the window.


The solution:
You need to reset the stage’s projection centre on stage resize, like so…

Embed tag gotchas in Flex SDK 4

In moving to compiling projects with the new Flex SDK 4, I noticed a couple of gotchas to do with the EMBED metatag that I thought I’d share:

Runtime Shared Libraries
If you wish to embed assets in your SWF with the EMBED metatag, so you can manage and update things easily, there’s an extra compiler parameter you must add, in order for your project to compile properly:


This is already added as a new default parameter in FlashDevelop projects. But if you’re planning to build projects from outside a similar IDE, you must add this to your compiler string. Otherwise, the compiler will think you have uninitialised constants and warn you so.

Embedding Fonts
Using the EMBED metatag, or even better runtime loading, for fonts is the sensible way forward. The amount of projects I’ve seen where you need to build from an FLA file full of fonts, which you need to hunt down and install is crazy. With Flex SDK 4, you’ll need to add an extra attribute to your embed tag for fonts, called ’embedAsCFF’:

[Embed(source=’myfont.ttf’, fontName=’MY_FONT’, fontWeight=’regular’, unicodeRange=’U+0020-U+0040,U+0041-U+005A’, mimeType=’application/x-font’, embedAsCFF=’false’)]
public static const MY_FONT :Class;

Happy compiling!

Flash 10 Matrix3D demo

I quickly cobbled together this little demo using the new native 3D transforms in Flash 10. Alongside the regular transform.matrix property, DisplayObjects now have a transform.matrix3D property, which controls its appearance in 3-D space. It’s pretty easy to play with in Flash CS4, without any coding knowledge – I can’t wait to see a version of GTA built using this 🙂
