If you've got existing ActionScript assets but want to migrate them to another language, what do you do? One possibility is to convert AS3 to TypeScript . They share similar language features, but are different enough that the process isn't trivial.

There's a project called AS3toTypeScript by Richard Davey that runs through lots of simple replacements, like converting Boolean to bool . It's written in PHP and can be used with a web interface.

In From AS3 to TypeScript by Jesse Freeman, the author converts a game to TypeScript, which seems like a typical task for an ActionScript developer. He points out that TypeScript works well because of the Visual Studio support, so it makes sense if you're a Microsoft-based developer.

François de Campredon recently sent me as3-to-typescript (License: Apache , npm: as3-to-typescript ). This is a Node-based project that includes the AS3Parser from Adobe. That means the conversion process actually parses ActionScript and attempts to output syntactically correct TypeScript.

The tests are fairly minimal given the goals of the project, but they do show what the tool currently supports. I'm not particularly for or against ActionScript or TypeScript, but as3-to-typescript is a very interesting and useful combination of technologies that might help you find new life for old game code.
