Animating Dynamic text onto the screen letter by letter

private function setInitialContentForCaseStudy():void{

more_mc.solution_txt.text = “”;//clear to start

solutionString = solutionsArray[0];

animationCounter = 0;

animationTimer = new Timer(100, 0);

animationTimer.addEventListener(TimerEvent.TIMER, animateContent);

animationTimer.start();

}//setInitialContentForCaseStudy

private function animateContent(event:TimerEvent):void{

more_mc.solution_txt.appendText(solutionString.charAt(animationCounter));

animationCounter++;

if(animationCounter == solutionString.length){

animationTimer.stop();

}//if

}//animateContent

Beware of other stuff happening at same time or too much text – can be slow!

Array – randomly re-arrange array

Someone simplified code, found somewhere; sorry whoever:

var arrayA:Array = new Array(“A”,”B”,”C”,”D”,”E”);

//var randomPage:Number = Math.round(Math.random()*(arrayA.length-1));

//trace(arrayA[randomPage]);

for(var i:Number = 0; i < arrayA.length; i++){

arrayA.push(arrayA.splice(Math.floor(Math.random()*arrayA.length), 1));

}

trace(arrayA);

Arrays – Finding string information in arrays

Find in array based on naming the sprite as per current array index value, such as ’1_mc’:

var nameString:String = event.target.parent.name;

nameString = nameString.slice(4); //depending on its name

var numberString:Number = parseInt(nameString);

tempCounter = numberString;//or value in array e.g. trace(imageBigArray[numberString]);

————

Better, if the name is not a number:

var nameString:String = event.target.name;

for(var k:Number = 1; k < servicesArray.length ; k++){ //ignore first one in this eg

if(servicesArray[k] == nameString){

more_mc.need_txt.text = needsArray[k];

}//if

}//for

————–

Better yet, look for a string in the array:

for (var i:Number = 0; i < allVideoPaths.length ; i++){

if(jsParameterPassed == String(allVideoPaths[i])){ //where passed parameter could be “myvideo.flv”

videoURL = allVideoPaths[i];

}//if

}//for
