Re: [Flashcoders] Clear Set Interval Q:
And for as often and inaccurate as they want to fire, I often think the best solution is to check time change from the last frame to the current with whatever method. I assumed Intervals only fired once per frame, but apparently they fire as often and as accurate as they 'can'. If I remember correcty there were some tests done when setInterval was first introduced and it turned out that setInterval can fire approx. 10 x per frame. But alot depends on what else is going on while the interval runs and that number may/will drop. Oh, I now just spotted that your sample code shows those same numbers (11x per frame) ;-) regards, Muzak ___ Flashcoders@chattyfig.figleaf.com To change your subscription options or search the archive: http://chattyfig.figleaf.com/mailman/listinfo/flashcoders Brought to you by Fig Leaf Software Premier Authorized Adobe Consulting and Training http://www.figleaf.com http://training.figleaf.com
RE: [Flashcoders] Clear Set Interval Q:
I got to thinking...
The problem with setting a single interval using setCurrentInterval is that
you can only have one interval running at a time, while the problem with
clearAllIntervals intervals is being forced to reset those you want to keep.
So I just wanted to share another idea, clearing all intervals EXCEPT those
you want to keep.
//
// CLEAR ALL INTERVALS - EXCEPT
//
function clearAllIntervalsExcept ( a:Array )
{
var x = {};
for ( var i in a ){ x [ '_' + a [ i ] ] = 1; };
// create new interval
var id = setInterval ( this, 'blank', 0 );
while ( id != 0 )
{
// count through all intervals and clear them one by one
// except those defined in the array
if ( !x [ '_' + id ] ) clearInterval ( id );
id--;
}
}
function test ()
{
trace ( arguments );
}
var _1 = setInterval ( this, 'test', 0, 1, 0 );
var _2 = setInterval ( this, 'test', 0, 2, 0 );
var _3 = setInterval ( this, 'test', 10, 3, 10 );
var _4 = setInterval ( this, 'test', 100, 4, 100 );
var _5 = setInterval ( this, 'test', 1000, 5, 1000 );
var exceptionArray = [ _4, _5 ];
clearAllIntervalsExcept ( exceptionArray ); // only _4 and _5 will run

Clearing the previous interval works as expected. I'm showing the same
example with a little more padding to illustrate how it might be better used
inside another function - the benefit being the ability to still keep track
of the most current interval id.
//
// ONLY ONE INTERVAL

function setCurrentInterval ()
{
var id = setInterval.apply ( null, arguments )
clearInterval ( id - 1 );
return id;

}

var id = setCurrentInterval ( this, something, 10 )
var id = setCurrentInterval ( this, something, 100 )
var id = setCurrentInterval ( this, something, 1000 )
trace( 'ID: ' + id );
Personally I hate intervals, and I don't mind saying that. For all the
problems they cause due to scope issues and whatnot, but unfortunately you
can't avoid them if you really care about time. So I say just clear them
all.

}

RE: [Flashcoders] Clear Set Interval Q:
The most sensible way to use Intervals, which are very useful - but
dangerous when not managed correctly, is to use an implementation of
TimeOut, so you fire object methods after a given delay and the API you
use for this, automatically clears up the interval. I can speak from
experience as to the annoyance of debugging code where setInterval /
clearInterval has been used irresponsibly.
Eg:
class TimeOut
{
public static function create(interval : Number, scope : Object,
method : Function, parameters : Array) : Void {
var intervalID : Number;
var timeoutFunction : Function = function() : Void {
clearInterval(intervalID);
method.apply(scope, parameters);
};
intervalID = setInterval(timeoutFunction, interval,
parameters);
}
}
Usage:
import TimeOut;
function someFunction(arg:String) : Void{
trace(arg);
}
TimeOut.create(5000,this,someFunction,[I should be called after 5
seconds]);

I think you're missing out by not using Intervals. They're extremely
useful (and efficient) once you get familiar with them.
If you're looking for one that you don't have to keep track of, google
Kenny Bunch Interval Manager. It takes care of a lot of interval
overhead and puts all intervals in one location (namespace).
To Muzak's point, I'm able to have multiple instances of the same class
each have their own interval running inside them. Do you mean if you
make the interval var static?

Re: [Flashcoders] Clear Set Interval Q:
clearInterval stops an interval from executing, it doesn't remove the ID that
was assigned to the interval.
From the docs:
quote
setInterval:
Returns
Number - An integer that identifies the interval (the interval ID), which
you can pass to clearInterval() to cancel the
interval.
/quote
Each time you call setInterval a numeric identifier is returned, which is auto
incremented as you can see in your example.
And this also explains why it is so important to clear an interval before
creating a new one, which was mentioned a few times here
recently.

Muzak

Re: [Flashcoders] Clear Set Interval Q:
you could try
clearInterval( intervalID);
delete intervalID;
and then wait for the garbage truck to drive by and pick it up...

An interval ID is just a number. If you clear the interval, it doesn't
get rid of the number, it just stops the interval of that ID from running.

Re: [Flashcoders] Clear Set Interval Q:
So once you create a new interval with the same name you will lose the path
of the original?
/*SAMPLE
Of course we know this is not the way to do it ;)
Its just for testing purposes */
var myInterval:Number = setInterval (this, test, 1000);
var myInterval:Number = setInterval (this, test, 1200);
var myInterval:Number = setInterval (this, test, 1400);
var myInterval:Number = setInterval (this, test, 1600);
clearInterval (myInterval);
function test() {
trace(hi);
}
In this case we now don't have access to interval 1,2 and 3 and of course 4
was cleared.

clearInterval stops an interval from executing, it doesn't remove the ID
that was assigned to the interval.
From the docs:
quote
setInterval:
Returns
Number - An integer that identifies the interval (the interval ID),
which you can pass to clearInterval() to cancel the
interval.
/quote
Each time you call setInterval a numeric identifier is returned, which is
auto incremented as you can see in your example.
And this also explains why it is so important to clear an interval before
creating a new one, which was mentioned a few times here
recently.

Muzak

Re[2]: [Flashcoders] Clear Set Interval Q:
HG So once you create a new interval with the same name you will lose the path HG of the original? An interval has no name, it has a numeric ID - what has a name is the variable (or more variables if you want) where you store this ID. And yes, if you doesn't care about storing the ID (e.g. you overwrite it), you will lose information which is required for clearing a specific interval.
