Lets say I add a callback function to be run every frame the AS2 way.
Code:
this.onEnterFrame = myFunction;
If I add another enter frame listener, will this replace the old one, or add to the old one, so both functions will run when frames are entered? And how do I remove these listeners?
How do I execute callback functions dynamically by passing a function in as an argument to another function?
Look at this example:
Code:
package {
public class myClass extends MovieClip {
public function myClass(callback) {
[code]....
How would you write this into a function that lies on frame 1:
onClipEvent(data){
this.sendSent.text = "MESSAGE WAS SENT";
this.textEmail.text = "EMAIL";
this.textSubject.text = "SUBJECT";
this.textName.text = "NAME";
this.textMessage.text = "MESSAGE";
}
I'm trying to add a custom callback handler to a NetStream client in a p2p application. The problem is, when I add such a handler, the NetStream Client doesn't function as it did before. It seems the NetStream.client object is changed. I know the default object is this. But changing the client to this doesn't solve the problem. The remoteControlStream, is the incoming stream. And the localControl stream is the stream being published. This is the localControlStream that's being send by the peer, and received as remoteControlStream:
private function initLocalControlStream():void{
localControlStream = new NetStream(nc, NetStream.DIRECT_CONNECTIONS);
localControlStream.addEventListener(NetStatusEvent.NET_STATUS, localControlHandler);
localControlStream.publish(myPeerID+"control");
var localControlStreamClient:Object = new Object();
[Code] .....
The onPeerConnect method of the localControlStream doesn't get called when I connect when the above handler is added. When I remove the that handler, the onPeerConnect method gets called. Obviously the problem is the NetStream.client.
fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?
From what I understand, this should work:

How do I keep the cycles active, and also call a function at the end of each cycle/tween? Right now I can remove the soundHammer call back and the tween will continue to cycle, and if I remove the cycle soundHammer is called properly, but obviously it doesn't cycle anymore.
I'm working with arrays in AS3 and some of the utility functions described in the livedocs such as filter() or some() would be very useful to me, if only I could pass parameters to them...
Actually, I cannot find a single example of the use of these functions with custom parameters passed to their callbacks. Everywhere, it is always used with constants ! E.g. on this page: [URL]
var arr:Array = new Array();var totalElements:uint = 100;for(var i:uint = 0; i<totalElements; i++) { arr[i] = Math.round(Math.random()*100);}function isLargerThan90(element:*, index:int, arr:Array):Boolean { return element > 90;}var highestNumbers:Array = arr.filter(isLargerThan90);trace(highestNumbers);
What I need is a kind of "isLargerThan" function with "90" as an argument's value, not as a constant. Something like
function isLargerThan(element:*, index:int, arr:Array, param:Object):Boolean { return element > (param as Number);}I find it very odd that I cannot find no mention of the way to do this on the whole WWW, because that makes these utility functions absolutely helpless in many many cases and programming with arrays a real pain...
My web application pass a javascript object to flex application using addCallback function.
when the flex application is in modal dialog in safari browser, the object in the flex application is null and when I open the flex application just in a new window, the object is passed correctly. But, I need the showmodaldialog to show the flex application.
The flex code:
ExternalInterface.addCallback( "handleEvent", handleEvent );
override public function handleEvent( event:Object ):Object {
Alert.show(String(event)); .....
When you call a method of a class inside a callback function, you can not use this object.To call the method, in javascript, I declare that variable, assign this to that, and use that inside the callback to call the method of this.In actionscript, do I have to do the same way as I do in javascript?The following code is the example to use that to call a method inside callback.Are there more simple way in actionscript?

import caurina.transitions.Tweener;
class Scanner extends MovieClip
{
public var Scanner00_mc:MovieClip;
public var Scanner01_mc:MovieClip;
[Code].....
Makes sense as for the sequence, what doesn't make sense is why Tweener fail to loop back to the "fade" function ? They are suppose to be calling each other in an astable/blinking manner.
I suspect it's a scope problem but I don't know how to fix this, it seems AS2 Class doesn't know that there is a fade function within itself after the second Tweener call.
I rarely use NetStream or any video in my projects, but someone I email with was wondering this, and I have no earthly idea.
Is there any reason why the NetStream's "onMetaData" event cannot be listened to using addEventListener, but instead requires you to use a callback function?
Is it faster, avoiding the overhead of events? Is it to prevent more than one listener being attached?
I'm currently working with soundmanager2 in an IE/flash context (not html5). The issue is that audio playback of mp3 content does not occur for the following case where the 'onload' callback function is defined as null OR as a function that does almost nothing.
[Code]...
I don't think this is possible, but is there a way to validate the arguments a callback accepts. For example someone passes me callback "mycallback", I want to assert it accepts an argument String.
public function addHandler(handler : Function) : void{
//pseudo code
Assert.functionAcceptsArguments(handler, String);
}
whenever I try to call the removeMovieClip function in a callback handler, it just doesn't work! Maybe I'm tired, or I've just missed something this is apparantly obvious. In my code exert below, is just a simple script that attaches a movie clip to stage (square_mc) and creates a duplicate instance. When the component button is clicked, I want the original movie clip to be deleted, but nothing happens!
Code:
this.attachMovie("square", "square_mc", this.getNextHighestDepth());
square_mc.duplicateMovieClip("square_mc2", this.getNextHighestDepth(),
{_x:50}) var listener:Object = new Object;[code].............
it seems to me that when you use laco tweens and callback a function, you can't pass data in that function, because the function won't wait until the tween is finished but is being carried out right away. For instance, I want to tween movieclip MC:

I've got a really weird problem that I've boiled down to its fundamentals, and I'm hoping that someone here smarter than I am knows why AS3 would be acting this way. Attached is a ZIP with a few FLAs and .AS files. I'm using Flash CS5. Please bear with me as I explain the situation.
I have a class called TestChildA:
package testing
{
import flash.display.MovieClip;
[Code]...
For some reason, the fact that we're not trying to obtain a TestChildA reference allows the Frame 0 ActionScript in TestChildA.swf to execute properly. TestChildB, on the other hand, continues to fail Frame 0 execution since we're still getting a reference to it.
As we saw in the first version of the INIT handler above, querying the test_str variable out of the loaded content directly without trying to cast it worked fine. Why is it that using 'as' to get a specific reference to the content with the proper class results in the Frame 0 script of that content to fail running? Theoretically, the Frame 0 actions should have already been executed prior to reaching the INIT handler anyway, so it's doubly confusing.
If anyone has a better understanding than I of the ActionScript internals and can explain the reason for this issue,

View 1 RepliesThe type of "for loop" in question:
for (i=1; i<5; i++) {
theClip="clip"+i;
eval(theClip).onPress = function() {
found(i); // passes the i variable to a hypothetical "found" function
}
}
"theClip" evaluates correctly, i.e. clip1, clip2, clip3, clip4.
The i inside the callback function is useless though. Every clip's onPress function will pass 4 (the last loop #) to the "found" function. I must be totally missing some basic restriction on callbacks.

View 1 RepliesI have a website and it functions fine but I want to make a few alternate versions, exactly the same only they start on a different frame. I tried adding a gotoAndStop(9); into the actionscript on the first frame drag all clips when i drag single movie clip(which only contains event listeners and functions) but for some reason part of it goes to frame 5 and part of it does nothing. Only when I click the button that links back to frame 1 does frame 9 load.
