use of button to increase and decrease the timer in action script3.0 - actionscript-3

Question

I have written a code to add two buttons. It shows them correctly, but the action is not performed correctly.
public class butt extends Sprite {
public function butt() {
var delayGlobal:Number = 2000;
var min1:Number =1000;
var myTimer:Timer = new Timer(delayGlobal);
myTimer.addEventListener(TimerEvent.TIMER,runMany);
myTimer.start();
// Button Event
myButton1.addEventListener(MouseEvent.CLICK, myButton1Click);
function myButton1Click(ev:MouseEvent):void {
delayGlobal = delayGlobal- 1000;
trace(delayGlobal);
}
myButton2.addEventListener(MouseEvent.CLICK, myButton2Click);
function myButton2Click(ev:MouseEvent):void {
delayGlobal = delayGlobal + 1000;
trace(delayGlobal);
}
function runMany(e:TimerEvent):void {
var loader:Loader=new Loader();
var url:String= "http://google.com.example2";
loader.load(new URLRequest(url));
addChild(loader);
}
}
}
The timer is shown but doesn't work

Answer 1

Your issue is that you are updating a variable, but not actually updating the timer at all.
You need to explicitly tell the timer to change the delay. myTimer.delay = delayGlobal
Here is a re-working of your code:
public class butt extends Sprite {
private var min1:Number =1000; //assuming this is your minimum allowed delay?
private var myTimer:Timer;
public function butt() {
myTimer = new Timer(2000);
myTimer.addEventListener(TimerEvent.TIMER,runMany);
myTimer.start();
// Button Event
myButton1.addEventListener(MouseEvent.CLICK, myButton1Click);
myButton2.addEventListener(MouseEvent.CLICK, myButton2Click);
}
private function myButton1Click(ev:MouseEvent):void {
myTimer.delay = Math.max(min1, myTimer.delay - 1000); //This will assign whatever is bigger, min1 or the timer delay less 1000 - ensuring that the timer doesn't drop below the value of min1
trace(myTimer.delay);
}
private function myButton2Click(ev:MouseEvent):void {
myTimer.delay = myTimer.delay + 1000;
trace(myTimer.delay);
}
private function runMany(e:TimerEvent):void {
var loader:Loader=new Loader();
var url:String= "http://google.com.example2";
loader.load(new URLRequest(url));
addChild(loader);
}
}
