An AS3 profiler
NOTE
This post has been previously published on 2007/Oct/17: due to my move to another server i’m now in the process to manually recover the comments for this article. Fixed!
I’m currently working on an early-stage, more of a proof-of-concept thing, but i needed to know more about the code performances: googling for an ActionScript profiler just showed up ASProf, an AS2 profiler. So i decided to port to AS3 the C++ profiler i wrote for Aqua, the cross-platform framework i was working on until April: the original C++ implementation has been developed after being inspired by an article of Steve Rabin in the Game Programming Gems 1 book, that’s a nice one to have on the shelf together with some other great books of which i could post something about them later.
It is always wise to remember that if you are serious about code profiling, you’ll be better to search for some professional tools: in the C++ arena my choice would be this one, but if you plan to have lunch and dinner for the next couple of months give Eletric’s one a try, it really deserves a look.
Unfortunately for the AS3 world, i just haven’t found anything really usable for it up to now, so i just thought to release it under a zlib/png license and some hints on how it works here.
ProfilerConfig.Width = stage.stageWidth; ProfilerConfig.ShowMinMax = true; prof = new Profiler( 32 ); addChild( prof );
