Flash Scripting: temporarily blocking events

Hi all, there was a question how to prevent images coming in too fast, for example if images are loaded on webcam activity.

The principle is to use a timer to get the delay.
The timer starts and a blocker is put in between the events coming in and the loading.
After the timer has expired, the blocker is removed.

You can use a Number as a blocker, using 0 and 1 for example but  here we use a Boolean.

A boolean can only be true of false (0 or 1).

var stoppingEvents:Boolean = false;

we use a delay timer, when it starts events will not cause reactions:

var delayTimer:Timer = new Timer(1000); //timer delay is 1000 milliseconds
delayTimer.addEventListener("timer", goOnListening);

This is how we stop events:

function keyDownHandler ( event:KeyboardEvent ): void
{
if ( stoppingEvents == false )
{
if (String.fromCharCode( event.charCode) == "1") //the active key is "1"
{
readSound("1.mp3");
stoppingEvents = true; //blocking the next 1000 milliseconds any sounds
delayTimer.start();//count down to give the listener free
}
}
}

we have started the timer here, when it is done:

function goOnListening (event:TimerEvent ) {

stoppingEvents = false;
delayTimer.stop(); //stopping th timer
}

it removes the blocker....

of course this example can be used for blocking mouse events, webcam events, microphone events just as easy....
