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 using this in your projects, so that Flash instances needn’t fight for CPU and give Flash 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!

Blue lego block of ambiguity

At the risk of getting sucked into the Apple vs Adobe shitstorm, my own response to Apple chosing to block Flash content from their mobile devices is to at least tell users why – because Apple left it at the rather obscure blue lego block, with no explanation (great experiential design guys). Simply include this code in your page/s to redirect mobile safari users to a page of your chosing …I direct them here.

Local playback security in FlashDevelop and Flash CS3 / CS4

I’ve seen a few people get into a pickle over this one. When you’re developing and testing locally, you need to set the ‘Local Playback Security’ setting (sometimes referred to as the ‘use network services’ option) depending on whether you wish to access local external files (e.g. XML files, or images) or some other server (e.g. your dev backend server). You can’t access both from a locally running SWF anymore, since it’s a security risk. So here’s how to set that option in Flash CS3 / CS4 or from within FlashDevelop.
