[Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Let me explain the problem I am having and then I will send you some code. I
want to load up images in a slide show with set interval, with the images being
called image1 image2 image 3 etc. I want to be coding a dynamic slide show so
that if I change the images I can just replace the mc images.
here is the code I am working on, I am a little new to setInterval (completely
new to that function actually) - I do understand the basic syntax,
setInterval( function (){ //entire function here;},1000);
But I don't know how to run a for loop inside it and pass a variable to it. (I
am a newbie).
function loadImages(){//Ihave this here so I can run an external for
loop.
for(i=1;i6;i++){
setInterval(function(){ //set interval and begins anonymous function
i.e function() -no name
attachMovie(image+i,image+i,41); //trying to attach the images,
image1 - image5
image = eval(image+i);//instance assigned to
variable 'image'
image._x = ((Stage.width / 2)-(image._width/2)); //positioning
image._y = (yFactor);//positioning
oldwidth = image._width; //saving
dimensions for resizing formula
oldheight = image._height;//saving
dimensions for resizing formula
image._height = yheight; //image height
set to variable
image._width = ((oldwidth*yheight)/oldheight); //image width set to
proportions of original
},1000);
//interval to 1 sec. 1000 milliseconds
}//end
for loop
} //end container
function
I am trying to set the images up for a second and then have them switch.
Help me out if you you know a solution. Or even if you see some obvious
errors. Like I said I am new with the set interval. by the way if you like
that little resizing technique, you can use it. Thank you.
Looking forward to a response on this one.

RE: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Paul:
I understand what you're trying to do (make a time-delay slide show of
images).
Using setInterval for that is fine, but you have to make sure you're
using it correctly.
Calling setInterval will set up a flash system timer that will call your
function every X milliseconds.
It will keep going, and keep calling that function (every X
milliseconds), until it's stopped.
Hence, there is no reason for you to be calling setInterval in a loop
and setting up 5 timers (that will each repeat forever). Simply have 1
timer, that repeats 5 times, then you stop it.
To do this in simplified code:
//set up the call count.
_root.timerCalls = 0;
//make the function that will be called.
function foo()
{
trace(Timer function got called!);
if(_root.timerCalls++ == 4)
{
trace(Max calls reached. Stopping timer...);
clearInterval(_root.myTimerID); //timer will never get
called again.
_root.timerCalls = 0; //reset counter
}
//do stuff (every 1sec).
}
//make the timer, and start it.
_root.myTimerID = setInterval(foo, 1000); //system will call
foo() every second until you stop it. Timer ID gets stored into
_root.myTimerID.
This is just one way to do it. In your timer function, you'll implement
your code for loading the new image, and taking away the old one.

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
assign the setInterval to a variable than clear the interval this way :
var myInterval = setInterval(blah blah blah);
clearInterval(myInterval);
read about clearInterval on the docs... U'll realize it more

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Hi Paul,
actually what you should do with setInterval is something like
setInterval(functionReference, interval);
or to keep the scope of the interval : setInterval(this,
functionReference, interval);
secondly, if you want to load the image at a set interval, then your
approach is wrong. You should call setInterval to attach a new movie and
increment the count inside that interval.
There is no delay in a for loop, at least none noticeable enough in this
case. What is happening in your code is that all 5 pictures will appear
at the same time after 1 second. Don't know if that's what you aim for.
in the case you want the pictures to appear at a 1 second interval, your
code would become :
// if you're in a class do the following
private var myIntrvl:Number;
private var movieCount:Number;
// if not :
var myIntrvl:Number = 0;
var movieCount:Number = 0;
function loadImages() {
this.clearInterval(myIntrvl); // it's best practice to clear your
interval before setting it, you never know where it has been set before
myIntrvl = setInterval(this, doLoadImage, 1000);
}
function doLoadImage() {
movieCount++;
this.attachMovie(image+i, image+i, 41); // allways refer to the
movieClip you are attaching, in your case it's this
image = this[image+i]; // eval is deprecated in Flahs 8, so this
is a better syntax
// rest of your resizing code afterwards
}
Hope this helps !

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Ahh yes forgot something to stop loading images :
function doLoadImage() {
movieCount++;
this.attachMovie(image+i, image+i, 41); // allways refer to the
movieClip you are attaching, in your case it's this
image = this[image+i]; // eval is deprecated in Flahs 8, so this
is a better syntax
// rest of your resizing code afterwards
// When you have all 5 images, stop calling the interval
if (movieCount == 5) {
this.clearInterval(myIntrvl);
}
}

I take that back...never use it...you can always use onEnterFrame on the

When I was using AS2 I found that no matter what there were always memory
leaks with set interval and even after I explicitly tell Flash to remove the
interval it never got removed...
So even though I never wrote it I would offer the following advice, which is
to *almost* not use setInterval at all. Just use it once, for the root...
1) Move all functionality for intervals to a script on the root
2) The root is always available, and you won't have intervals all over the
place
3) Create only one interval for a function on the root which is responsible
for calling functions
4) The function should get the same sort of information as whats required by
setInterval.
5) Call functions based on the timer. Time since movie started. A little
math should test if the objects which are registered with your script should
be called again. I would also recommend enabling this function to support
something like call this function X times every 1000 ms). Rather than
call this object every 1000ms. That way you can delete it automatically if
its reached that number.
6) That script keeps information on what intervals are set
7) The script periodically checks for objects which no longer exists and
deletes them from the interval array.
8) Intervals are set or removed by calling a root function. Use the
delegate class to say which function gets the interval callback and also
pass a reference to the object.
Good luck,
Kalani

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
well I've actually created a class called SetTimer.as that executes a
function after a given time in seconds and can loop the function many times
u want..
see just put the class in the same directory of the fla and use:
import SetTimer;
var myTimer:SetTimer = new SetTimer(2, function () {myFunction();}, 5);
where 2 is the time to wait in seconds, the second attribute is the
function to be executed and finally 5 are how many times the function
will be repeated. if u don't set this last parameter the function will be
repeated only once...
hope this will help...
here is the class http://www.proeye.net/omarfouad/myClasses/SetTimer.as
Good luck!

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
As a posted last week or something, there's a few things to keep in mind when using setInterval - clear interval before setting it - always use this syntax setInterval(scope, method, interval) - and never use this syntax setInterval(function, interval) - keep a reference to the interval - remove it when done If things go haywire, you're doing something wrong and you probably forgot one of the above. If you're referring to everything using _root, code in the main timeline and advise others to do so, please join the flashnewbie list http://chattyfig.figleaf.com/mailman/listinfo/flashnewbie regards, Muzak - Original Message - From: Kalani Bright [EMAIL PROTECTED] To: flashcoders@chattyfig.figleaf.com Sent: Thursday, March 01, 2007 3:15 AM Subject: RE: [Flashcoders] Getting frustrated. regarding set Interval,and for loop.

Re: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Intervals are not a problem as long as you use them correctly.
Just make sure for every setInterval() call you have a corresponding
clearInterval() call. Usually the clearInterval() is within your interval
event handler function, so once the interval end condition is met, there's
no way for your code to exit without hitting it.
//PSEUDOCODE
var myInterval = setInterval(myFunc, 200);
myFunc(){
//do stuff
if(endCondition == true){
clearInterval(myInterval);
}
}
I've been doing things this way for a long time, and I can't even remember
the last time that I had a runaway interval problem. There's no need for an
IntervalManager class if you don't want to deal with that. (Nothing wrong
with it, but it might be overkill.)
Of course onEnterFrame is fine too if you're doing something in the context
of a MovieClip, but that may not always be the case. And with that there's
a danger that you need to look out for: if a MovieClip already has an
onEnterFrame handler, you could overwrite it...

RE: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
Always a pleasure having intellegent people prove me wrong. I'd rather be proved wrong by a singleton rather than a simpleton. My only comment is that setinterval doesn't fire accurately. If the user is moving the window for example the interval function will never get called. I like your manager but I still would use a timer. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Steven Sacks | BLITZ Sent: Wednesday, February 28, 2007 6:38 PM To: flashcoders@chattyfig.figleaf.com Subject: RE: [Flashcoders] Getting frustrated. regarding set Interval,and for loop.

RE: [Flashcoders] Getting frustrated. regarding set Interval, and for loop.
You can use a singleton. It's just important that the intervals be managed in a single location. _root can be used by as1 or as2 programmers. AS3 supports a document class and support for inner classes which means (through some creative engineering) singletons as well, no need for root. 1) setInterval is not accurate. Try moving the window around and see if the function gets called when it's supposed to. Keep a timer and compare the interval call to the time over say a minute to 2 minute period. You could be off by several or more seconds, and if you move the window around like crazy your 1 second interval could be called 7 seconds later. 2) Create your own class which does this. 3) onEnterFrame to check intervals (in a singleton) or single instance class, or root! 4) Even with a reference to the interval the interval may not always be deleted. Sorry, it's not. Do some tests. This is especially the case if you use delegates with your setinterval. The management problem for performance gets even worse. Making sure you delete and clear everything. But in my experience the intervals don't clear like they should even went set to self-destruct. 5) The 3 parameter setinterval call is not for scope, its for the object containing the method you want to call, if thats what you meant by scope. The object could be removed and the interval continue to be called. 6) Why go through all this headache when you can easily write your own interval class which is accurate and deletes itself when told? *regards* Kalani PS -(Try and be helpful rather than sticking your nose up at people) -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Muzak Sent: Wednesday, February 28, 2007 7:04 PM To: flashcoders@chattyfig.figleaf.com Subject: Re: [Flashcoders] Getting frustrated. regarding set Interval,and for loop.

You could be off by several or more seconds, and if you move the window around like crazy your 1 second interval could be called 7 seconds later. This is a player problem, not a setInterval problem. Same thing happens when you use onEnterFrame. Noone said setInterval is accurate, I think it even states in the docs it's not accurate. quote If interval is less than the SWF file's frame rate (for example, 10 frames per second [fps] is equal to 100 millisecond intervals), the interval function is called as close in time to the value of interval as possible. Executing long, memory-intensive scripts during an interval causes delays. If the function being called initiates a change to visual elements, you should use the updateAfterEvent() function to make sure that the screen refreshes often enough. If interval is greater than the SWF file's frame rate, the interval function is called only after interval has expired and the playhead has entered the next frame; this minimizes the impact each time the screen is refreshed. /quote 4) Even with a reference to the interval the interval may not always be deleted.
