View 2 RepliesIs it possible to use an addEventListner(MouseEvent.MOUSE_DOWN... to change an integer in a variable without using a function? So, you could have:
myMC.addEventListener(MouseEvent.MOUSE_DOWN, myVAR = 1); etc?
Obviously I've tried, but I get implicit failures.
I am trying to make an interactive flash application that works by detecting mouse overs and clicks on various buttons/movie clips and then moves to the appropriate part of the time line. But I am having an issue when I use more than one addEventListener in any one frame. I have attached the code for one such frame below. When I comment out the addEventListner and the other code relating to the followBall function this works fine and directs the user to frame Inlet_Valve_Open_Frame but now only the followBall function is working and when i try to click on the Inlet_Valve_Button movie clip nothing happens.
Can someone please help. I have never read all the help files on the adobe flash CS3 as i don't have time and i have built this code up based on examples i have found online. I wanted to include my fla file but it's to big 6Mb. But i have attached the swf so you have an idea what i am doing.

If in a situation, the addEventListener is being assigned more than once for same actionwhat will happen then? Suppose on frame 5 there is ample_btn.addEventListener(MouseEvent.CLICK...... ... and when user navigates the application/site it comes on frame 5 again and again. Will the addEventListener be applied more than once on that button? If yes then what will happen on clicking on that button? will the associated function be called more than once now?
View 5 RepliesI have made the flash file into CS3 and simplified the idea a bit. Basically I want to click the box on the right to start playing the song and the spectrum and then if I click it again it will stop playing the song and the spectrum then if I click it again it will start playing again ect ect. I could not upload the song.mp3 cause the file size was too big you will have to replace it with another mp3 in the root of the folder and name the mp3 song.mp3.
View 3 RepliesI want to do something quite simple, but am new to AS3 and the changes since AS2.I want to click a button (play_btn)Then when this happens it opens a SWF (movie.swf) into a placeholder (placeholder_mc) onto the stage. That's it!
play_btn.addEventListener(MouseEvent.CLICK, placeholder_mc);
function placeholder_mc(event:MouseEvent):void{
trace("pressed");
loader.load(new URLRequest("movie.swf"));
}
I have created a scrolling bar menu. All the buttons in the menu work except for the last two. When I place a trace statement within the function it definitely is listening to all the buttons except for the last two. All instances are named correctly. Can the size of the scroller be contributing to why the addEventListener is not working?

I have this map I'm creating in Flash. You click on a state, then you can click on an icon to view a tooltip/popup of some information. What I was trying to do was instead of creating new functions and event listeners for every different icon is to use a for loop...but it's not going so well.[code]...

View 1 RepliesI currently have a .swf file that is nested into another .swf file. In the parent SWF file I use a UILoader to load the other .swf file. uiLoader.source = "data/child.swf";- In the child SWF file I have stage.addEventListener(KeyboardEvent.KEY_DOWN,keyPressedDown); and when I run it on it's own, it works perfectly; but when I run child.swf through parent.swf stage.addEvent... give me a null reference exception. Is the stage part of what is causing the issue?, and if so, is there a way to fix this?
View 2 RepliesI want to add a series of event listeners. they work fine in individual lines of code:
ActionScript Code:
home.addEventListener(MouseEvent.CLICK, route);
resume.addEventListener(MouseEvent.CLICK, route);
portfolio.addEventListener(MouseEvent.CLICK, route);
contact.addEventListener(MouseEvent.CLICK, route);
but when i use this loop, i get a 1006 error, "value is not a function":
ActionScript Code:
var buttonNumber:Number;
var buttonName:Array=new Array("home","resume","portfolio","contact");
for (buttonNumber=0;buttonNumber<4;buttonNumber++) {
buttonName[buttonNumber].addEventListener(MouseEvent.CLICK,route); }
is there something obvious that's wrong with my last line in that loop? i've narrowed it down to the part where I call the array value. but after that - I'm at a loss!
I'm trying to use addEventListener with a SimpleButton object. In an earlier version of my movie, I had identical addEventListener code on a button from the library, and it worked great. But I had to switch to creating the button in AS3 instead, and now the code won't execute. [cpode]...

I have a for loop that loads a variety of movie clips that I want to have function as buttons. From what I've read adding an event listener is the way to go but I'm not sure how in this case. I've searched online and found a few articles that come close to what I need but not quite. Can't I just tack on an event listener for a mouse click on these objects and have it run a function I have defined elsewhere?Also in said function what code would I need to use to reference the button that was just clicked, would this. work?

Is it possible to create an EventListener about some event, and also sending some variable to the function that's called when the EventListener = true?

add an event listener to a button so you can see when it's been clicked but can you add one to a variable to perform an action when the variable changes or do i just have to use an onEnterFrame function to check the value and act on it if it's changed?
View 2 Replies[varible].addEventListener(MouseEvent.CLICK, [varible]);If so How? I have tried 50 different ways, with no success. The names of all of my buttons are creating in a for loop and numbered from XML. I need to call each one with a single line. I cant have an event listener for 600 buttons.
View 5 RepliesSo I have an MC that has 6 labels and 6 buttons all with different names. When you click on a button, it needs to direct you to it's appropriate frame label in the MC. Now, since AS 3.0 has done away with inline functions, how the heck do I code it so I don't have a function with a bunch of if statements inside of it in addition to all of my eventListeners that I have to add to each of my buttons? In AS 2.0, I would have done it like so:
Code:
function movePlayhead(whichOne:String):Void{
this.gotoAndStop(whichOne);
} button1_mc.onRelease = function():Void{
movePlayhead("label1");
};
button2_mc.onRelease = function():Void{
movePlayhead("label2");
};
Etc...
With AS 3.0, you have to add eventListeners to each of your buttons where each eventListener calls a function, but how can I write it so I don't have to write a bunch of if statements inside the function the eventListeners are calling in order to test for which button is being clicked? Like so:
Code:
button1_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button2_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
button3_mc.addEventListener(MouseEvent.CLICK, movePlayHead);
function movePlayHead(event:MouseEvent):void {

I am creating an app with Papervision, and I'm trying to create an interactive grid.I have created a for loop to lay out each tile of the grid, but I want each tile to be individually interactive. I have tried a few things but no luck so far. This is basically how far I am:
Code:
for (var i:uint = 0; i < 10; i++) {
for (var j:uint = 0; j < 10; j++) {
[code].....
I have a variable
var pageState:uint = 0;
The only values of that variable will be 0 (ZERO) and 1 (ONE).
I need to set a kind of Event Listener. Each time the variable changes:
if (pageState == 0){
x = 10;
}else{
x = 0;
}
How can I set an addEventListener to this?
I can't seem to override flash native addEventListener with a custom addEventListener. My code:
Code:
package {
import flash.events.*;
public class myClass extends EventDispatcher {
[code]....
But anyway, my problem is that, I have 52 Button instances on Scene 1 as bellow:
B1 , B2 , B3 , ... , B52
and I want to assign seperated actions for each of them.
The way I currently CAN do that is this:
B1.addEventListener(MouseEvent.MOUSE_DOWN, B1F);
B2.addEventListener(MouseEvent.MOUSE_DOWN, B2F);
B3.addEventListener(MouseEvent.MOUSE_DOWN, B3F);
[Code].....
But "test.addEventListener(..." does not work, and Flash searches for a function named "test" instead of working with the VALUE of "test".
I've been browsing lots of forums lately regarding the issues involved with passing parameters into functions called by event listeners. I think I may have come up with a good solution using anonymous functions but I'm not sure yet if its "safe" to do.
Code:
this.addEventListener(Event.ENTER_FRAME, function(e:Event):void {
myFunction(e, arguments.callee, "hello")
});[code]....
The code prints "hello" once, which is what I wanted. I believe I have deleted the anonymous function, but I need some thoughts from those who may be more knowledgeable about flash garbage collection and such to be sure.
Im making a cooking game and basically I have my buttons and background export to the stage, which is good, but now I want to make it so when you click on the mustard it exports the mustard movieclip to the stage.For some reason I am getting an error that does not make any sence to me.

I am trying to build a simple mock-up of a product my team is designing and I can't seem to get the addEventListener to work. At the moment, my mock-up contains code that Alex Lexcuk has written that deals with the page flipping animation. I suspect that it might be interfering with the addEventListener code I have written. I have placed my addEventListener code inside the Content symbol. I have uploaded my project to the following URL:[URL]
View 6 RepliesThe problem I've found that I keep having and that is pretty recurring between a few of my classes is that several classes use addEventListeners for complete events on loaders, tweens, etc. The question I have is, how do I catch those events in the event that the instantiated class object is removed from the swf file? Because the eventListener keeps listening, for some reason(I assume the object is removed from the stage but garbage collector doesn't get it right away).
My current, most prominent example is this:I have a photo album that utilizes php to import filepaths on the server. There are basically 2 stages: one screen where all the albums are displayed, and another screen where all the images for a given selected album are displayed.
The problem is that when you click one of the albums, it loads all the images from that album and THEN transitions to the viewing page. This is good because it doesn't load all the images from all the albums.
The problem is, it's possible for the user to click one album, and really quickly, before the "album" page fades out, click another album.
If I've managed to not twist your brain inside out with this poor explanation, you may see that the loader object for the previously clicked "album" button will still be loading the one of the previous images. So, when the complete event for the loader is fired, I get this:
Error #2044: Unhandled IOErrorEvent:. text=Error #2124: Loaded file is an unknown type.
Which I assume, obviously, is 2 separate error events. I'm already using error catching that's working for another purpose, but I just can't catch these ones no matter where I put my catch statements. Any help?
Here's the code:
Code:
function clickHandler(event:MouseEvent):void
{
//////some stuff here
////////preps album images for display
[code]....
The first type error gets caught. It loops back through and works fine when you only click one button at a time, but otherwise it freaks out. I just don't know where to put the catch statement so that it just shuts up...
