The easiest way to build this app is to use Adobe Flash Builder 4.7+:

  • Simply checkout this repository and then select File/Import Flash Build Project.
  • Select the repository folder and click Finish.
  • Then select Run/Run.

You could possibly use Apache Flex to build, however this is an exercise for the reader.

Conversion Tutorial

This tutorial will cover the process of converting an existing FLA animation to SpriteBuilder, you will be using some awesome artwork kindly donated by Vincent Le Quang, Melissa Wallace and Anna Klonoff.

Note: You will require both FLA source files and the published SWF for any content you wish to convert.


Open pika.fla (CS5+), you should see a few funky looking creatures in various colours. To keep things clean create a New Document and select ActionScript 3.0, I called it bluebeast.fla.

Select the blue creature from pika.fla and copy this into the new bluebeast.fla document.

Double click the Pika run symbol from the library.

Hit play to watch this majestic beast run like the wind, would make a nice endless runner character....

Getting ready to export

Step 1) In the library view open properties for Pika run and ensure advanced options are expanded, tick the Export for ActionScript, then tick Export in frame 1, the base class should be flash.display.MovieClip.

Great this will now be picked up as an animation for the conversion tool, you then need to ensure all of the component parts of this animation can be exported as textures. You can see various symbols such as Eye, EarFront and Horn in the Library view.

Step 2) Select all of the symbols from BackLeg down to Tail, ensure Pika Run is not part of this group selection and then edit properties.

Step 3) Tick type and ensure Movie Clip is selected from the drop down. Tick Export for Actionscript and change the dropdown to Yes, don't worry about any warnings. Tick Export in frame 1 andchange the dropdown to Yes. Tick the Base class and enter flash.display.Sprite. Hit OK.

Step 5) Hit Publish

Ok you will most likely have some Compiler Errors. Not a problem, let's fix this right now, double click the first error message. A window will popup, clear the text stop();, close that window and save. Hit Publish again, great, it should be all working now.


Open SWF Importer

Step 1) Select the directory containing your bluebeast FLA and published SWF files. (I find it best to put these files in their down directory)

You should see bluebeast listed in the Conversion Summary, if valid does not say Yes then you need to go back and check you followed the previous steps correctly.

Step 2) Select an export directory, if you want to export into an existing SpriteBuilder project then select the SpriteBuilder Resources folder inside the desired .spriteBuilder project.

Note: As of SpriteBuilder 1.2 this folder will be Packages\SpriteBuilder Resources.sbpack

Step 3) Select the bluebeast and hit Preview, looking good. Close this window.

Step 4) Hit Export All.

You should now have a file called bluebeast_pikarun.ccb and a bluebeastAssets folder in your export directory. If you exported directly into your project these files will now appear in your project resources.


Great let's see these in action in SpriteBuilder. If you didn't drop these straight into an existing SpriteBuilder project, you can easily create one try it.

Note: The CCB export has been tested against SpriteBuilder 1.1

Step 1) Create a new project, I called it 'bluedemo', it will open up the MainScene. Right click on MainScene.ccb in the File view and select Show in Finder.

Step 2) Copy the files from the export into this directory and then click back to the SpriteBuilder view. In a couple of seconds you will see bluebeat_pikarun.ccb appear in File view tab.

Step 3) Open this CCB and hit play, you should see the bluebeast running. That's it!

Common issues that cause "ERROR" in the converter

  • The timeline of the animation symbol you want to publish cannot contain another symbol inside. The items in the timeline should contain/use only tweens.
  • Make sure that the publish target inside the Publish Setting is set to the latest Flash Player version. Publshing the animation with old Flash Player versions can cause an error.
  • The final animation that you want to convert should be in a symbol, not a scene.
  • All the tweens used in the timeline must be present in the library section when publishing the animations.
  • The published .swf file should have the exact same name with the .fla file.

Common issues that cause "Missing texture" in SpriteBuilder

  • The converted ccb files and assets folder should be copied into the root folder of the SB package. If they're placed inside another folder(s), it will cause the "missing texture" issue in SpriteBuilder.
