I’ve been using this for a long time now, it’s a debugger that runs in another SWF and is passed trace statements via my Debug class, with different levels or detail, info, warning, event, classinfo, error etc. It also has a runtime monitor graph at the bottom, the yellow line showing the current framerate, and the blue line showing the time it takes to execute all threads currently running in the Kernel class. The Kernel is basically a single onEnterFrame on a MovieClip in the _root, which runs through an array of threads, I simply have a getTimer() at either side of the thread execution and time it, this is a great way to view code-weight, especially when developing games or persistent enviornments such as physical engines.

I will make a public release of the Kernel, Thread and ThreadGroup classes soon, which will also include the debugger.

I’m currently putting together a library for release under a GPL license. It will include animation management classes, a core kernel and threading engine to remove the reliance on onEnterFrame events, and a debugging tool.

This lib is aimed at Flash Developers who predominantly work on animation intensive sites, rather than application development.
