Random Array Elements In Dynamic Text Box

[4mylgl6]

Hi,



I have an array (named arrayFull), and I want my dynamic text box (named messageText) to display one random element from the array, changing once per second.

The code I have makes it display all elements of the array at once in random order, changing once per second.

How do I make it display just one element from the array at any given time?

This is the code:



var arrayFull:Array = new Array(1,2,3,4,5);
import flash.utils.Timer;
import flash.events.TimerEvent;

var myTimer:Timer = new Timer(1000, (arrayFull.length));
myTimer.addEventListener(TimerEvent.TIMER, runOnce);
myTimer.start();

function runOnce(e:TimerEvent):void {
messageText.htmlText="";
updateText ();
}

var maximumMessages:Number = 1;
var currentMessages:Number = 0;
function updateText(){

for (var i = currentMessages; i<maximumMessages; i++) {
messageText.htmlText += arrayFull.sort(function () {
return Math.random() ? true : false;
});

for (i = 0; i < 4; i++) {
this[i].text = arrayFull[i];
}
}
}

Thank you for your help.

messageText.htmlText += arrayFull[int(Math.random() * (arrayFull.length-1))];

Thanks a lot! I've tried the same approach before, and forgot to use the int before the parentheses.

Is there some way I can prevent it from showing the same element twice in a row?

outside your function, create a variable to save the last shown random element:

var lastShown:Number; 

then when you assign it, check to make sure it doesn't match that - then set it again until it doesn't match. then set the lastShown variable to that new element:

var randomElement:Number = arrayFull[int(Math.random() * (arrayFull.length-1))];
while(randomElement == lastShown) randomElement = arrayFull[int(Math.random() * (arrayFull.length-1))];
messageText.htmlText += randomElement;
lastShown = randomElement;
