Adobe flash cs4 tutorial: Typewriter Effect


var str:String = "On Enter Flash go and support the learning. Why does a lined brain calculate within the helmet? Ere dodges the retrieval over the sexist. The distinguished rescue errs. After ere prevails the basket. An acid interrupts er. A mayor chooses across the official. Flash shines on top of an incomprehensible dummy. The lover bores underneath the worry! A cat paces adobe underneath the ironic winter. A deaf typewriter produces the swamp. Another worthwhile example manipulates flash within the insensitive slang. Why can't adobe pull an invaluable juice?";

var timer:Timer = new Timer(10);

var i:uint =0;

timer.addEventListener(TimerEvent.TIMER,gotime);

timer.start();

function gotime(e:TimerEvent){
 textbox_txt.appendText(str.charAt(i));
 i++;
 if(i>=str.length){
  timer.stop();
  }
 }

Do you know if there it's possible to have the lettering fade in as they appear? It would make it look a little smoother, but I imagine it would require much more complex coding.

Thanks for all you do, sir :-D; June 29, 2009 at 2:36 PM
Anonymous said...: After, what it seems like HOURS and HOURS and searching for the simplest AC3 typewriter code, this is by far the BEST and easiest to follow. Thank you! I will definitely be on your site more often.; August 27, 2009 at 10:08 PM
Teresa said...: Ok, I have not been using Actionscript that long. I just tried your typewriter script and although it works, I cannot get past the first frame! When I try to add another layer and then add some frames to it, it keeps giving me this error when testing the movie...

TypeError: Error #1009: Cannot access a property or method of a null object reference.
at cotc_cube_fla::MainTimeline/gotime()
at flash.utils::Timer/_timerDispatch()
at flash.utils::Timer/tick()

How do I get this to work with more than one frame?; August 27, 2009 at 11:03 PM
Anonymous said...: have the same error: #1009.

any advice?; January 26, 2010 at 5:42 AM

Kelly said...: This helped me tremendously, but can I ask if you want it to forward to a second screen to show more text typing how would that be done? For example, when that first window finished it would clear and continue to type again on a clean screen.
