How to implement complex actionscripts in flash movie using SWF Scout

Updates in 2.xx version: now you can use built-in source code actionscript compiler instead of using extracted bytecode as shown in this tutorial.

We recommend to develop complex scripts in Flash MX or another flash software with ActionScript support and then compile SWF code. Using the free SWFMixer utility (see below) you can get the compiled script bytecode for further use with SCRIPT_ methods.

This tutorial will teach you how to get compiled script bytecode.

Create and test FLA project with the complex script:

Flash MX main window

 

Flash MX code editor

 

Now we will export this flash project as SWF file. Go to File menu and select Export Movie in Export sub-menu:

Flash MX file menu

 

Review SWF flash movie properties and press OK to save SWF file:

Flash export settings

 

Enter the filename and click Save to save SWF file:

Flash movie save dialog

 

Now run SWFMixer utility and click Open to open SWF file:

SWFMixer open button

 

SWFMixer will show content of SWF file. Click on PlaceObject2 tag to view details about Place object

PlaceObject2 tag in SWF

 

Click Copy Actions Bytecode to copy the bytecode to the clipboard:

Copy actions bytecode

 

SWFMixer will copy the bytecode to the clipboard:

Copied bytecode dialog

Now you can use this code to add an actionscript to your flash movie generated with SWF Scout

VB code that uses compiled bytecode extracted using SWFMixer:

' KeyPress.vbs. You can find source code of this example along with required files
' in "Examples\More Examples" sub-folder
' Bytecode was extracted from KeyPressEvent.swf. You can find this file in "Examples\More Examples" folder as well
