ActionScript 3.0 :: Run Event Listener Through Dynamic Object Call?
Apr 27, 2009I have a movie clip being dynamically added to the stage via an AS3 linkage call:
gameOver_mc = new GameOver();
stage.addChild(gameOver_mc);
The movie loads as required.But when the movie has been added I want the user to be able to press spacebar and a function to run.So in the GameOver.as class I wrote the following:
Code:
package
{
import flash.ui.Keyboard;
[code]...
But as soon as the movie clip tries to load I get the error message: TypeError: Error #1009: Cannot access a property or method of a null object reference.I would have thought this would work fine. When I trace the statement in the Constructor function is works. Its only when I try to add an event listener that I get the problems. So am I not allowed to add event listeners from a dynamically loaded class?

ActionScript 3.0 :: Keyboard Event Listener Doesn't Call On Function
Jul 5, 2011The keyBoard event listeners call on the rotate and unrotate functions and based on the key inputs(A and D) will implement either of the functions and rotate the image or return it to the original upright position. However, I haven't been able to get the function to work. When I press the A or D keys on the keyboard nothing happens. I even put trace() in one of the functions to see if the function will even be implemented but I don't get anything. I put in my Scripts below. Why are the functions not working? Do the eventlisteners fire or are there conflicts? I'm not getting any error messages.
ti.border = true
ti.addEventListener(TextEvent.TEXT_INPUT, onInput);
function onInput(event:TextEvent):void {
if(ti.text.search('a')!=-1) load_image("http://i54.tinypic.com/anom5d.png", "ottefct");

Actionscript 3 :: Simulating A Click Call To A Button(displayObject) Thats Generated Via An API Call?
Nov 2, 2011I'm having trouble simulating a click call to a button(displayObject) thats generated via an API call( youtube as3 API). I have not seen any mention of security reasons as to why I can not simulate a click as long as something is registered with a click handler. Basically I checked to make sure the button made is listening to a mouse click event with:
trace(generatedButton.hasEventListener(MouseEvent.CLICK)) which returns true
I proceed to than call this:
generatedButton.dispatchEvent( new MouseEvent(MouseEvent.CLICK, true) );
And nothing happens yet if I physically click the button it works. Is there some security measure that prevents something from being fake clicked unless its origin is strictly from the system mouse?
I even set a timeout call on the click function and moved my cursor over the button and let it fire in case it was an issue of the mouse having to over the object but still nothing. I am kind of stumped at this point.

Flash - Listener In Main Document Class For Custom Dispatch Event From Another Class Does Not Respond Or Call Function?
Apr 1, 2011I have a document class called Main.as In the class constructor I have the following listener:
enter code here
var listeningFORModeChangeToStudent:Sprite = new Sprite;
listeningFORModeChangeToStudent.addEventListener(TellAllModeChangeToStudent.STUDENT,exp);
addChild(listeningFORModeChangeToStudent);
[code]....
In a third class I make a call to the despatcher in the previous class:
enter code here
var ThisTellAllModeChangeToStudent:TellAllModeChangeToStudent = new TellAllModeChangeToStudent;
ThisTellAllModeChangeToStudent.tellAllModeChangeToStudent();
I have trace statements in eveything and from this I know the despatcher in TellAllModeChangeToStudent is being called.The problem is that the listener in the main.as is not calling the function exp.I cant see why and I dont know how to check if the listener is actually seeing the dispatch event?
ActionScript 3.0 :: Flash Button Scripting For Xml Loaded Swf - Call A Button?
Feb 10, 2011how to call a button. I have a main file ("AS3Build.fla"), which imports an xml file, and imports different swfs depending on which node in the xml is being referenced. One of the swfs("slide_01_03.swf") I'm importing has a button("btn_01_01") that I'm having trouble accessing. First of should the script for the button be in the swf that holds the button, or the main file that will be importing the swf? I've got it in the swf currently with a trace file to see if it's recognizing the click. So far not luck. So I'm starting to think it should be in the main fla, and be referenced something like: this.loader.addEventListener.btn_01_01. This doesn't seem to work either though.

ActionScript 2.0 :: Button Listener Class?
Aug 31, 2009i am trying to define a button state class where i can give the class some params and have it load a thumbnail (large files were a previous problem for me on this) that will be displayed upon rollOver. i'm having some troubles with a couple of key points:
1. i don't know how to pass in a reference to a movieClip that i can refer to in order to change its state (x location, for example) 2. i don't know how to send a status message to the host script (main timeline AS code will need to deal with such a message) after the img has been loaded
*both of these would REALLY help me understand some of the mechanics involved with AS2 OO programming,

View 5 RepliesActionScript 3.0 :: Button Event Listener Get Removed?
Nov 8, 2010I'll keep this simple (I hope). There's a button with an event listener on a frame of the main timeline. You click the button to go to the next frame and a movie clip plays. The instance of that button doesn't exist on that next frame. Does the event listener for the button automatically get removed when you go to that frame since the button doesn't exist there?
The movie clip is set up to send the main timeline back to the previous frame when it's finished and my event listener seems to vanish when I go back to that frame.
Actionscript 3 :: Button With A MouseEvent.CLICK Listener?
Aug 8, 2011I have a button with a MouseEvent.CLICK listener. The CLICK event is being triggered when the button is pushed, mouse is down while rolled out, then released when rolled in on the button again. I do not want this to happen, the click event should not occur when the button is being dragged.
My flash file contains a large amount of buttons and click listeners, I would like to solve this problem with as little code as possible. What is the simplest solution to this problem?
ActionScript 2.0 :: Button Event Listener Does Not Work
Aug 31, 2009I'm creating a minesweeper game as my first flash project, but I'm already stuck on something technical. I have created a button named Button which contains a bitmap. I have a lot of instances of that button on stage, and they are put there by actionscript using a for-loop. Their instance names are button0, button1, button2, button3, etc.
This is the code for the eventlistener: It's in the first keyframe of the actions layer.
var buttonListener:Object=new Object();
buttonListener.click=function(evt:Object):Void{
trace("clicked");
} for (i=0; i<rows*cols; i++) {
eval("button"+i).addEventListener("click", buttonListener);
}
I also noticed that when I do this for one button that I created myself and put on the stage manually, this also doesn't work, but when I pick one of the predefined buttons, it works just fine.

View 2 RepliesActionScript 3.0 :: Clicking On A Button Destroys KeyboardEvent Listener?
May 5, 2009I have a basic presentation which will have basic interactivity for the user. i.e. The user clicks on a play button, and the presentation plays, the user clicks on a back button, and the playhead steps back through the animation.I also want to provide keyboard shortcuts to do the same thing, so the user can also hit the spacebar to play the presentation, or press the left arrow key to step back, etc.I've successfully gotten both the click interactivity and keyboard interactivity to work... but only separately, when I try to add them to the same file, it breaks.I also think I've figured out why. The problem seems to be that if I click a button that is only on the timeline for SOME of the frames, the KeyboardEvent listener no longer triggers.
I have a rewind button that will jump the playhead to the start of the presentation. However, from a use design standpoint, I really only want the rewind button visible/clickable if the user has advanced a bit into the presentation (i.e. frame 2 or beyond) because having the rewind button active on the first frame of the presentation can be confusing because it makes it appear to the user as though they can still rewind further, even though they've reached the beginning. I want to take a similar approach to a play button... as long as there are frames to play, the play button should be active; however, once you reach the end, the play button should dim down and not be clickable anymore, which serves as a visual cue to the user that they have reached the end of the presentation.
So, previously (in AS 2.0) this was not a problem. On the frame I wanted the rewind button to be "disabled", I would just turn the Button Symbol into a Graphic Symbol which would make it unclickable and remove any script, and then I would dim the Alpha of the Graphic. So, on frame 1, the rewind button would actually just be a transparent Graphic, and then once the playhead goes to Frame 2, it would be a Button symbol that could be clicked.
This technique apparently will break the new event model in AS3. If you look at the FLA I have attached, you can see that when you first "Test Movie"... any keyboard press outputs a trace statement that shows which key was pressed. However, if you hit the play button to play a little of the timeline, and then click the rewind button (instance name of rewind_btn) which jumps the playhead to frame 1 (where rewind_btn doesn't exist, because it's a Graphic now).
