Loan Shark – fast object pooling utility

LoanShark AS3 Object Pooling UtilityA couple of years ago, I created an object pooling utility for a games project I was building in AS3. Since then, I’ve used it quite a few times, in order to speed up apps and improve resource management, easing the load on the garbage collector by reusing objects instead of recreating them.

SWFIdle – simple flash idling utility

If you’re still churning out Flash banners, please use this!

swfidleI created this simple utility, called SWFIdle, to enable the Flash Player to lower its CPU usage while the user is not interacting with it. Since it’s possible to have multiple Flash instances embedded in one page (for example, a game and a couple of banners), I recommend that everyone uses this in their projects, so that players needn’t fight for CPU and give a worse name than it has already.

I know there’s the hasPriority embed attribute now. But:

  • That assumes you have access to the HTML that embeds your SWF
  • If no other players are present, it has no effect
  • There’s still usually little reason to be running your SWF at a high framerate if the user isn’t interacting with it
  • Flash banners with wastefully unoptimised drawing routines are probably one of the key reasons that Flash got poo-pooed off of mobile platforms and disabled on everyone’s laptops – CPU usage = battery usage!

The solution:
You need to reset the stage’s projection centre on stage resize, like so…
