    I’ve used this for a ton of projects

  3. ekameleon Says:

    You can add VEGAS and this extensions (an opensource architectural and RIA framework)


    Work in AS3/SSAS and AS2.

    EKA+ :)

  4. Adrian Parr Says:

    Cheers ekameleon,

    I’ve now added it under ‘OOP Frameworks’.



  5. darron Says:

    FVNC can be listed here as well:

    It includes a Flex library project that supplies a VNC-viewer component, as well as an example Flex project using the the FVNC library.

  6. Jim Armstrong Says:

    AS3 Parametric Curve Library –

    Online Demos and TechNotes –


    - jim armstrong

    Hi Darron,

    It’s an honor to see you here. Sure thing I’ll add that project. It is now at the end of the list.

    All the best and keep up the great work,


  8. zoh Says:
    AMFPHP-wordpress integration

    Thanks for including Gaia in your list, Adrian! :)

  13. niLS Says:

    Hi Adrian,

    Thought I’d share these two OOP/IOC/DI Frameworks, which we use quite frequently in production:
    Parsley –
    LowRa –

    If one comes from Spring (Java), their architecture will feel instantly familiar.

    @Jim: Awesome project/documentation, wondering why I didn’t run accross it before.


  14. Adrian Parr Says:

    Hi Nils,

    Thanks for those, I’ve added them to the list.

    Jayrock in AS3

  16. Adrian Parr Says:

    Thanks Pieter,


  17. M;cha31 Says:

    I would also include Desuade’s Partigen – an excellent particle engine.

    It’s not free, but it’s extremely powerful.

  18. Adrian Parr Says:

    Hi M;cha31,

    Thanks for the tip off. I’ve now added Partigen to the ‘AS3 Particle Systems’ section.

    Oh, and it’s CS4 version is integrated in my library called CJLibrary CS4.

    Emitter comes with a tool called Emitter Config Object Generator,
    which is essentially a particle editor.
    You can quickly tweak parameters and generate the corresponding code.

  32. Adrian Parr Says:

    @Allen: Thanks mate. I’ve added it to the ‘Particle Systems’ section. Nice work.

  33. a_[w] Says:

  42. ANU Says:

    Hi Adrian Parr,
    I need solution to integrate youtube video to flash/As3 environment. please help me

  43. Adrian Parr Says:

    Hi ANU,

    To integrate YouTube videos into Flash I reccommend you have a read through the following page …

    There is a Flash example and downloadable source files available.

    You’ll need the two ActionScript classes from choppingblock – ‘’ and ‘’. These are included in the ZIP file.

    You’ll also need the ‘youTubeLoader.js’ file.

    It’s pretty straightforward. Good luck.

  44. equ Says:

    Other Missing AS3 Libs:

    * SWFAddress – Deep linking for Flash:

    * Flash Camouflage – skinning framework for AS3:

    * Flexlib – Open Source Flex Component Library:

    * Yahoo Astra Flash Components http :

    BTW – your spam protector is annoying. I can’t even post links beacause I still get following message:

    “Hmmm, your comment seems a bit spammy. We’re not real big on spam around here.”

  78. Miguel Martín Says:

    Hello Adrian, I saw your comment on flex-frameworks on mcorlan’s site and I want to share our MVC framework with you too. It’s called CycleFramework:

    “CycleFramework is a view management and development oriented framework for applications implemented with actionscript3 and flex technologies. It is developed and mantained by Cycle-IT.
    CycleFramework is specially useful for management-like applications, where the different view states follow a root-branch-leaf pattern clearly: the application will have a well defined navigation tree.”


    License: Open source (MIT)

  79. Adrian Parr Says:

    @Miguel: Thanks for letting me know about CycleFramework. I’ve now added it. Cheers.
