Change the opacity of an instance when a dynamic text field reaches a certain value

Hey there, I'm pretty new to AS3 but I'm trying to get a small action to work as a test case for a project at work. Basically there will be a dynamic text field that is counting up from 0 to 999 (call it dtext_1), when dtext_1 hits a certain value (999) I want to make another instance (unlocked_mc) visible. I was thinking that I could start unlocked_mc at alpha 0 and switch it to 1 when the number is hit? I'm just not sure how to go about it exactly.

So : I'm basically trying to transpose "when dtext_1 >= 999, unlocked_mc.alpha = 1" into something useable in AS3. Any suggestions?

Thanks!

You can use the function that is updating your text. Something like this:

import flash.events.Event;

stop();

unlocked_mc.alpha = 0;

var myNumber:Number = 0;

dText_1.addEventListener(Event.ENTER_FRAME,addUp);

function addUp(event:Event):void {

  myNumber ++;

  dText_1.text = myNumber.toString();

  if(myNumber > 999) {

  unlocked_mc.alpha = 1;

  }

}

Presumably there is a variable that is counting up, that you then put into the text field? Like this at the start:

var counter:int = 0;

unlocked_mc.alpha = 0;

and this each time it increases:

counter++;

dtext_1.text = counter;

If that's the case you could check the value of the counter each time it's increased:

counter++;

if(counter>=999){

  unlocked_mc.alpha = 1;

}
