Usually only talk music and video in this blog, but as I don't have a professional blog atm (maybe I should) here's a cool Flash thing I did. I wanted to do a typewriter effect, you know where each letter types on - top Google hit is this very old-school solution with some mistakes. So I recoded it with a function and clearInterval, it types then continues when finished, this way you can change the speed of the text by changing the interval. You could do it with onEnterFrame but I like setInterval, far more flexible as you can change the interval, although you could do a counter so your mileage may vary :-) You need a textfield called 'question' on the timeline, and that's all. stop(); var txt:String "This text is being typed out by code. Isn't it cool?"; var max:Number length(txt); var loop:Number 1; var interval:Number; function typeLoop() { clearInterval(interval); loop++; question.text substring(txt, 1, loop); if (loop>max) { trace("finished"); gotoAndPlay("qfade"); } else { interval setInterval(typeLoop, 50); } } typeLoop(); Yes it could be whizzier - this is Actionscript 2, not 3, you could do a class, but to my mind that's cracking a nut with a sledgehammer! Simple but I have more complex stuff I do, maybe I should share it... Yup this is my day job, although more animation than code....
