Authoring Guidelines

Authoring for Flash Player 33

To use the new Flash Player, you will need to target SWF version 44 by passing "-swf-version=44" as an extra compiler argument to the ASC 2.0 compiler.  Detailed directions are below.

  • Download the new playerglobal.swc for Flash Player 33
  • Download and install Flash Builder 4.7 from Creative Cloud: https://creative.adobe.com/products/flash-builder
  • In Flash Builder, create a new project: File -> New -> project.
  • Open the project Properties panel (right-click and chose 'Properties'). 
  • Select ActionScriptCompiler from the list on the left.
  • Add "-swf-version=44" to the 'Additional compiler arguments' field.
    • This ensures the outputted SWF targets SWF version 44.  If you compile on the command-line and not in Flash Builder, you need to add the same compiler argument.
  • Ensure you have installed the new Flash Player 33 build in your browser.

Reporting a Bug

Found a bug? Please submit a bug to the Flash Player bug database.

Flash Player may leverage your graphics hardware to decode and play H.264 video. There may be video issues that can only be reproduced with your particular graphics hardware and driver. When reporting an issue involving video, it is essential to note your graphics hardware and driver, along with your operating system and browser (when using Flash Player), so that we can reproduce and investigate issues. Please be sure to include this information as described in Instructions for Reporting Video Playback Issues. Note: Due to the high volume of email we receive, we are unable to respond to every request.

Thank you for using Adobe® Flash Player® and for taking the time to send us your feedback!
