DIGG IT! There are several tricks to working with Intervals that makes them easy to manage and change.&
The ids for intervals are numbers globally in the player. When you create an interval with setInterval, it returns a unique id for the interval you set starting with 1 and iterating higher.
myInterval = setInterval(function(){trace('I1')},100)
trace(myInterval) //1
myInterval = setInterval(function(){trace('I2')},100)
trace(myInterval) //2
myInterval = setInterval(function(){trace('I3')},100)
trace(myInterval) //3
//clearing the intervals you have set it even easier.
clearInterval(1)
clearInterval(2)
clearInterval(3)
Another interesting patterns is creating a generic Interval function that you can add functions into. The following function will attempt to execute every object stored within the function.
intervalCore = function(){
var self = arguments.callee
for( var x in self) self[x]()
}
myInterval = setInterval(intervalCore,100)
intervalCore.one = function(){trace('one')}
intervalCore.two = function(){trace('two')}
intervalCore.three = function(){trace('three')}
//delete the items in the interval:
delete intervalCore.one
delete intervalCore.two
delete intervalCore.three
Or if you simply want to clear out all the Intervals within the Flash Player:
i = setInterval(function(){},100) + 1
while(i--){
clearInterval(i)
}

Great post! Nice to see cool stuff like this every now and again. Thanks for sharing, I will use this bit of code to some work, because I was felt that intervals where a pain to deal with.

It might be nice to roll some of this functionality into a higher level Interval class to make intervals easier to work with.
Interval.add( name, function , delay, props)
Interval.remove( name )
Interval.removeAll()
Interval.start( name )
Interval.startAll()
Interval.stop( name )
Interval.stopAll()
Interval.list() //returns interval data
Cheers, ted ;)
Gret discovery on the auto incrementing globals. Removing all intervals should be a handy debugging technique.

Kenny Bunch just released his IntervalManager class over at his blog. May be exactly what you mentioned in your previous comment...

You just absolutely made my day. That clear all intervals snippet was essential for a program I was running that would load the same flash file at various difficulties. You rock. :)
