I’ve been asked a few times how to create effects that require multiple instances of the Flash Player on a page to remain ‘in sync’, even with user interaction. Reading and writing to cookies frequently is inefficient and resource heavy. Also, when you have more than 2 SWFs, deciding which SWF updates who becomes tricky – especially if someone decides to change or remove an instance, or an instance which you picked as ‘master’ is not loaded, for some reason.
So, I came up with this solution, using LocalConnection with a twist, which works pretty well. But, if anyone has a better method, drop it in a comment below 🙂
The line dynamics itself is just Hooke’s law stuff – basic physics. Took some experimentation to get a smooth curve drawn through a series of points (basicaly, the control points of your previous and next points need to be in line).
If you can’t see the demo above because you’re on mobile, or don’t have Flash enabled on your browser, you can see the banner in action below:
The cars follow one of the line’s points with differing elasticity and damping, but the real pain in the backside was drawing the dashed line via code, in crummy ActionScript. Luckily, I’m a persistent bastard 🙂 Read more about it on Bannerblog.
I created this microsite for Dare Digital back in 2005, to promote a competition running alongside BBH‘s Vodafone ‘Mayfly’ TV campaign. Users can create a mayfly with a personal message attached, which lives for just 24 hours and wanders around the environment. The best life-affirming message won a drive around Monza with Michael Schumacher in his Ferrari!
