Blinking Random Number Generator ActionScript3 - actionscript-3

Question

I need a random number generator on AS3 that blinks on a screen one random number per second (1-9). The random number is fine but I'm having a problem with the blinking part. It just stays permanent on the screen instead of blinking the number.
The dynamic textbox is called myNumbers. I've tried using myNumbers.visible = !myNumbers.visible on the event handler, but it didn't work.
My code:
var mytimer:Timer = new Timer(1000,10);
mytimer.addEventListener(TimerEvent.TIMER, timerHandler);
mytimer.start();
function timerHandler(event:TimerEvent):void{
var numbers:Number = Math.floor(Math.random() * (9 - 1 + 1) + 1);
myNumbers.text = numbers+"";
}
Any help is appreciated!

Answer 1

You can use the same Timer to generate a number (every second) and blinks your text field (every 0.5 second).
Take this code :
var number:int = 0;
var timer:Timer = new Timer(500);
timer.addEventListener(TimerEvent.TIMER, timerHandler);
timer.start();
function timerHandler(event:TimerEvent):void{
if(timer.currentCount % 2 == 0){
text_field.alpha = 0.2; // you can use text_filed.visible = false;
} else {
text_field.alpha = 1; // you can use text_filed.visible = true;
number = Math.floor(Math.random() * 9) + 1;
text_field.text = String(number); // you can also write it : number.toString();
}
}
Which will give you something like this :
Hope that can help.

Hide the myNumbers before start a timer:
myNumbers.visible = false;
In the timerHandler add:
myNumbers.visible = true;
setTimeout(hideText, 500);
Add hideText function:
function hideText()
{
myNumbers.visible = false;
}
