Well, I dont really get the problem, but you can check out my motionfeeder
Class if you want to
It does what you look for, and has some additional features as well...

Subject: Re: [Flashcoders] Asbroadcaster and setinterval
both are correct, that isn't the problem.
the interval get's called properly
function fireInterval(){
trace("A");
this.broadcastMessage("onInterval",this.event);
}
^^ this traces "A" infinitely
But the message never gets broadcasted, so it enters the function, but it
doesn't broadcast the onInterval event.
Then I checked if it was any problem with the whole AsBroadcaster thing not
set up correctly, so I fired the event on a keydown event:
function keyDown(){
this.broadcastMessage("onInterval",this.event);
}
this DOES broadcast the onInterval event..
so the interval function get's fired, but doesn't fire the onInterval event
for some mystical reason...
whereas another event(Key event in this case) CAN fire the onInterval event
I'm quite stuck on it actually :/

Not shure if I got your problem right, but if you are using an object
where
the function exists which you want to
execute with your interval, the syntax should be something like :
intervalId = setInterval(this, "sendMessage", intervalSpeed);
where "this" is a reference to the object where the method ("sendMessage")
you are calling is located.
"intervalSpeed" should be a number.
When Braodcasting the message, the first parameter is the name of the
method
you want to get called, and the second (and following) parameters are
optional parameters to be passed on to the executing method.

Subject: [Flashcoders] Asbroadcaster and setinterval
Hello,
I'm trying something that might be obvious, but somehow isn't. What I'm
trying to do is broadcasting a message on a setinterval basis.
I've set up my events broadcaster class and it worked quite well.
The problem i had with it was that it extended MovieClip.. The only reason
for this was the onEnterFrame function, seemed a waste.
I came up with this to replace the onEnterframe and subsequently have the
eventbroadcaster class extend Object instead of MovieClip:
this.intervalID=setInterval(this.fireInterval,interval); <---- in the
class'
constructor
function fireInterval(){
//_root.log.log(this._listeners);
this.broadcastMessage("onInterval",this.event);
}
Now, i've traced within the fireInterval function, and it works fine.
Problem is, the listeners never get the onInterval event broadcasted to
them.
When i do this(it also listens to key events):
function keyDown(){
this.broadcastMessage("onInterval",this.event);
}
it DOES work... So i'm quite stumped here,
first of all the fireInterval function gets executed, but the listeners
never hear it and
secondly, when I have a key event broadcast the event, the listeners DO
hear
it...
What's the problem here? Don't AsBroadcaster and setInterval like each
other?
thanks,
Meinte
