ActionScript 2.0 :: Timeline Events - Add Listeners And Send Out Dispatchers?
Apr 30, 2009
In my SWF, I have a movie clip that I wish to play itself immediately after the site loads. I have two other movie clips that are required to play once the first movie clip has reached frame 13. This is a function that I would like to repeat, as the first movie clip (followed by the other two) will be required to play the others after certain mouse events within the movie.
PHP Code:
hello_button.addEventListener(MouseEvent.CLICK, click_handler);
function click_handler(event_object:MouseEvent) {
/* Do something with this event */
}
While others import class objects and operate under package headings when describing how to add listeners and send out dispatchers.

I have a base class, and I created a class to connect to C# to which it sends and receives data. Now I want the base class to know when the Connector Class has received data and to get that data. so custom events are the answer right. But no matter how much documentation I've read, I can't get my head around this. My current class, if I extend EventDispatcher the base class can pick up fine but I need it to get the data that it received as well. So I extended Event and I've put a listener on my base class but it's not picking up the event (in fact although it's compiling it seems its breaking my connection to the C# as my C# client gets an error).
Should my connector class be extending Event or EventDispatcher. Then if it extends Event, I need to create another class to dispatch the event? someone said to me I don't need events as the callback will handle it, but my callback is in my connector class not the base class.

Here's a hodge-podge of information:
Custom Event Class:
Code:
package com.events {[code]...
I made a custom loader to replace the urlLoader and even tried a replacement for the _loader using the same custom event.Works great for the first addEventListener:
Code:
urlLoader.addEventListener(Event.COMPLETE, onSwfLoaded).But stops on the second addEventListener.If I just apply the custom event to the following...
Code:
_loader.addEventListener(Event.COMPLETE, onLoaderInit);
VERSUS
Code:
_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onLoaderInit);it works just fine.As soon as I use it on the contentLoaderInfo line, it throws that type error cannot convert CustomEvent to Event error.I also double checked that my custom event listener was overriding clone()properly and it looks like it does.

I have a movieclip on the scene. I also have a button on the scene and when I press the button I want to send a variable-value to the movieclip. I have a variable set in the actual frame on the main-timeline but the movieclip doesn't catch that, when traced I get undefined. Can I send a value from the main-timeline to a moviclips timeline?

I'm working on a web app built in Flash AS3. At a high level - the app has a main screen, and several "modal dialog"-type screens that pop-up to manage various user interactions. (This is a similar pattern I use in most of the apps I develop...) Typically - when the user clicks a UI control on the dialog screen (e.g., button, text box, slider bar, etc.) - the main screen needs to react, or manage the consequences. It seems like there are two general ways to handle this: Have the dialog screen dispatch events that the main screen listens for Allow the dialog screen to call functions in the main screen when those controls are clicked (which requires that the dialog screen maintain a reference to the main screen, and that the functions in the main screen are public)
In general - I understand that one of the key benefits of the first method is that the dialog screen isn't so tightly coupled; it's only responsibility is to broadcast the event. This would allow me to more easily use the dialog class in other contexts, or applications. But for many RIAs I develop - a particular screen is SO SPECIFIC to the the application that there's no chance I'd ever reuse it in another application. So, the "easy re-use" benefit is minimal. So - if you eliminate that benefit - which method is actually better? (More performant, less resource-intensive?) For example - if I use events, then Flash needs to manage many listeners for events that may never occur. So - it might be more efficient if the dialog window could call a function in the main screen directly, instead of dispatching an event.

I'm trying to make a program that grabs info from a text file then uses the info in the file to assign where certain balls will rotate (eventually I'll configure it to looking like dots rotating around an invisible sphere)Now, I can do these two things separately, load info from a file and make blue balls rotate around given points... but I've been tripping up hard on making them work together, and I think my problem is in how I handle the events and events listeners to work with the code, you'll need to start a new flash AS3 file Then on the stage create a circle with the oval tool convert the circle to a symbol named "BlueCircle" and name the linkage class as "BlueCircle" then paste this code...
Code:
var longLatLoader:URLLoader = new URLLoader();
longLatLoader.dataFormat=URLLoaderDataFormat.VARIABLES;
longLatLoader.addEventListener(Event.COMPLETE, onLoaded);[code]....

In my flash project I have numerous buttons that when hovered over or mouseOut an animation of that button happens. Everything works as it should, except if you pull the mouse away from the button very quickly. The animation gets hung up in its own timeline. I know that there is a way for the flash file to repeately check to see if the mouse is still in fact over the button. I couldn't find anything in the tuturials. If anyone knows the scripting on this

I have a Document class called Main.
As a child of Main, I have an instance of a class called NavMenu.
As children of NavMenu, I have multiple instances of a NavLink class: navLink01, navLink02, navLink03, etc.
Back up in the Main class, there is a function called navigateTo, which accepts sectionID variable as an argument.
My question is, what is the best practice to get the navLinks to call the navigateTo function on Main? I've been told that in the spirit of encapsulation, it is not best to pass a reference to Main down to the navLinks, and call the function from there.
But rather, it is desirable to use the event listener/dispatcher method, where the navLinks are dispatchers, while the Main class listens for the navLinks to broadcast their sectionIDs.
While this makes sense, however, don't you still have to pass a reference of the listener on the Main class down through the hierarchy, so that the navLinks are registered as dispatchers? Doesn't that defeat the purpose of encapsulation?

I am trying to create an on-screen keyboard for a touch-screen kiosk. Does anyone know how to send a keyboard event to a text input component from a button click event? For example, the user will push the on-screen buttons to enter their name, press tab to go to the next field, and so on.
I believe that I somehow need to use dispatchEvent but have not been able to get it to work. For example, pressing the on-screen A keyboard button will fire a CLICK event and call a handler to place an A in the currently focused text input component. The handler needs to be able to dispatch a keyboard event (with the correct keycode) to that text input field and that is where I am stuck.

I'm looking for a way to "inject" some events into a flash movie running on a browser. I know about ActionScript's ExternalInterface.addCallback function, however I'm trying to achieve this with any "random" flash from the web. Eg. send a "SPACE" keyboard event to a youtube video.

I came to the point where I need to communicate between 2 objects (let's say Tank and the Cannon). It is tile game, and when the Tank approach specific tile I need my Cannon to shot the Tank. When Tank gets that specific tile I want to dispatch some custom event and have listener in Cannon class body to make the shot happen. Other way I would have to check in ENTER_FRAME loop (inside Cannon body class) if the Tank touched tile that runs the Cannon shooting - but this is not elegant and efficient. The issue is complicated by the fact that the Cannon and Tank are added to the Engine (document class) and can't simply hear for each other, because they seat on the same level in display list.
Initially I could addEventListener to the Engine, but this way my document class would enlarge to the XXL size (all listeners functionality, all methods for game etc). What I would accomplish is to have event listener in every Cannon object (defined in body class) listening for Tank's dispatching the event. I saw some 'Centralized Event Manager' article in the net, but can't download full classes [url]...

I am looking for a simple timeline chart, that I can display several events on over a varying timespan. I haven't found any specific charts in Flex, has anybody created or used anything along these lines? [URL]

This is problem is cropping up in Flash CS3 rather than Flex, but it's Actionscript 3.If you paste the code below into the main timeline on frame 1 and test it in Flash, the COMPLETE and INIT events both fire. And in Firefox and Safari it works too. INIT and COMPLETE both fire. But in IE (6 and 7, both with the latest flash player) on a PC only the INIT event fires.
Code:
var debugText:TextField = new TextField()
addChild(debugText)
var onRootLoaderInit = function (event:Event):void{
debugText.text += "INITIATED." + " "
} var onRootLoaderComplete = function (event:Event):void{
debugText.text += "COMPLETE." + " "
} loaderInfo.addEventListener(Event.INIT, onRootLoaderInit);
loaderInfo.addEventListener(Event.COMPLETE, onRootLoaderComplete);

My homepage contains a flash file that tweens through 4 product images. I want to program my file so that every time the user goes to the homepage, the flash cycles through the four images randomly. I thought the easiest way to so this would be to create four series of image tweens and label each, and then code the first frame of the movie to go to one of the labels at random.

OK from the title you can tell I'm now a AS3 newbie. Its a shame because I was good intermediate at AS2 and all of a sudden I'm back at square one - and I'm no programmer so there's little chance of me learning AS3.
1) Back to the problem. I used to control events on my timeline with simple timers and such, utilising code like: _parent.MC1.Play(); Now that doesnt work, _parent and .root are gone, and I can't even get basic things to work anymore. I want to do is advance "MC1" to the next frame.
2) Is there a *simple* reference/summary of what happened to my old AS2 commands somewhere.

I have a navigation bar movieclip that has the following EventListeners in symbol definition:
news_btn.addEventListener(MouseEvent.CLICK, clickHandler);function clickHandler(event:MouseEvent):void { event.target.root.gotoAndStop(1,"newsawards");
categoryName = "news"; <<<DOESNT WORK}
clients_btn.addEventListener(MouseEvent.CLICK, clickHandler2);function clickHandler2(event:MouseEvent):void { event.target.root.gotoAndStop(1,"clients");}
[Code]...
My question is, how can i cause any of these events to change a string variable in the main timeline? For instance, i would like the news_btn when clicked to change already defined variable located in the main timeline. Also, is there a more elegant way to code the above, i'm new to AS3?

I created a menu of invisible movieclips (from a library item with the class name Invis) with buttonmode set to true so that I can have them send the playhead to different labels on the main timeline. I could use some help with determining which button is clicked and then placing code that executes depending on which button is clicked.
Here is what I have so far on frame 1 of my timeline:
This works - I get [object Invis]0,or [object Invis]1...etc in my output //window depending on which one I clicked. Just not sure what to do next

I am an AS3 code developer but this time I need to deal with a FLA that has an instance on timeline with complex nesting of movieclips and textfields (that are named via the instance field in Flash). The problem is that events (I put in the Documentclass) on nested movieclips inside that timeline placed instance are never dispatched.
example code:
// my instance on Stage in all Frames of the timeline
public var thewall:MovieClip;
// event directly on thewall works

I'm looking to send a list of variables (say 6 in total) from php to flash and for flash to pick a random one and send it back to php when clicking a button.
I would like it to appear in a dynamic text box. That randomly selected variable needs to be sent back to php on pressing a button.

Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?
I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?
By the way am using actionscript3 to implement the app.

I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).

with this code I call the class:
Code:
