ActionScript 3.0 :: Adding MCs From Event Parameters?
Jun 7, 2010
I'm trying to create a class that will allow me to associate MCs on the stage with MCs in the library. What I'd like to do is pass the linked library item as a parameter when I instantiate the class. For example, I might add an MC named "trigger1" to the stage in my FLA, associate it with the class, and try to pass the linkage ID for the library item it should control:
ActionScript Code:
var newTrig:LibTrig = new LibTrig (trigger1, Target1);
addChild(newTrig);
[code].....

I've exhausted searches looking for how to add properties to the component properties panel for a custom AS2 and AS3 components.This Adobe Livedoc suggests using Inspectable tags before variables:[URL]I've also tried adding the components via the Component Definition dialog in the library.Both methods work in that they produce an .swc, but neither adds the properties into the Component Properties.

I'm stuck with an issue and I cannot understand why it behaves like that. In a for loop, I'm passing the for index as an event parameter. However, the eventHandler is getting the wrong index, but the right target...

I am having a problem with stage event listeners in Explorer 7 and up.I place an object, say a circle, on the stage in layer 1. I make it a symbol and give it an instant name of myBall_mc.I add a blank keyframe at frame 25 and create a motion tween moving the circle across the stage.I add a new layer, name it actions and place the following code in the first frame.
stop();
stage.addEventListener(MouseEvent.CLICK, onClick);
function onClick():void[code].....
Works perfectly when testing. Works perfectly when exported to a .swf in Firefox. Doesn't work at all in Explorer 7 and up.If I add a button to the stage and change the event listener to listen for a mouse click on the button, it works perfectly in all browsers.
Now here's the weird part. If I leave the script exactly like I have it above and place a box, the entire size of the stage, over the stage and set its alpha to zero. It works perfectly in all browsers. This is without even changing the event listener from stage to whatever I called the stage covering object.It registers as a stage level mouse click!
I've tried to add imports but this didn't change anything. I tried to add the parameters ,true and ,false to the stage event listener after the function name. Everthting I've tried comes up short. The only thing that works for Explorer browsers is covering the stage with an object.

My project has a target object (center of stage) and a moveable object, which is created each time a user presses "Enter". Each movable object is identified as part of an array (i.e., object[i]), and a new line (i.e., line[i]) is dynamically drawn from the center of the newly created object to the center target object.
Basically, as the object is dragged around the screen the line is to stay connected to the target object. Therefore, that specific line for that object being moved must be redrawn using a drawLine function inside the event handler. My issue is how to get line[i] to be identified within the even handler? (Using AS3 coding)

I like reusing functions repeatedly so I pass the object to the function (blur, drop shadow, etc.) but if an Event or MousEvent function is involved, I have to do things I don't like. In my example, I had to put the TimerEvent.TIMER_COMPLETE function as a sub function of the setTimer function. I would rather keep the functions apart but I don't know how to pass a parameter to the event function to tell it what movieclip(timerObject) to fade in. Is there a better way to do this?

How should I comment an event handler param?I mean, should I comment event handler param?Example:TimerMessage class extends Timer.TimerMessage class, has a setMessage method, which stores a text message whithin its public var 'message'.in usage:
var timer_message:TimerMessage = new TimerMessage(1000, 1)
timer_message.setMessage('hello')
timer_message.addEventListener(TimerEvent.TIMER_COMPLETE, displayMessage)

I want to pass parameters when an event is triggered. My function:
private function keyChange(e:KeyboardEvent, setValue:Boolean):void
so that I can use the same function to set if a key is up or down. How would I write the event listener? I tried:
stage.addEventListener(KeyboardEvent.KEY_DOWN, keyChange(,true)); however that didn't work.

I'm looking off of this site: [URL]
Followed it closely and still nothing! I dispatch the Event alright from the first .as file and it runs the function featEvent() but that's as far as it gets. (found this out using trace statements)
Custom Event:
ActionScript Code:
package asFiles {
import flash.events.Event;
[Code].....
I believe the error is in the actual featEvent, but can't find where.

Suppose I want to create a bunch of buttons using a loop. But I want each button to do something different. Suppose the buttons are numbered and I simply want each button to print out its unique number when clicked. Heres what I have so far:
Code:
var t:CTextField;
for (var i:int = 1; i <= 100; i++) {
t = new TextField();
[code]...
Ive tried many different things to get this to work, but none of them worked so I wont bother posting them all. At best, I got it so every single button traced "button 100 was clicked". I sort of understand why that happened, but I dont know how to make it work properly. Once again, all I could find was people saying "use custom events", but I think I need a lot more details than that. For example, I dont see how changing
Code:
t.addEventListener(MouseEvent.MOUSE_DOWN, buttonClicked);
to
Code:
t.addEventListener(MySpecialMouseEvent.MOUSE_DOWN, buttonClicked);

I would like to pass Parameters to a functions from a button click. Currently I need to call a function that in turn passes the Parameters.
example
gardengate_btn.addEventListener(MouseEvent.CLICK, onClick_gardengate);
function onClick_gardengate(e:MouseEvent):void{
/*Sends the xml and the paintingCount_Numb to the parseXML function.
This will display the text and images for each painting
*/
ParseXML(xmlData,0);
}
I would think that i could just do this but it gives me an error. gardengate_btn.addEventListener(MouseEvent.CLICK, ParseXML(xmlData,0)); 1067: Implicit coercion of a value of type void to an unrelated type Function.

Look at the simple code below:
Code:
stage.addEventListener(MouseEvent.CLICK,traceMe);
function traceMe(evt:MouseEvent)
{
trace ("hello world!");
}
What if I want to pass a parameter to the traceMe function? There is a way to do that?

I know I can create a custom event and associate data with it and retrieve it in respective Event Listener. But What I am interested to know is, is there a short method (without having to extend Alert Event Class) to associate parameters to its alert Listener.

I have a 16x16 grid of buttons, and want to add an event listener to each of them so when clicked it will return its unique grid position number (anything between 0-255);
What I have so far:
public static const GRID_SIZE:Number = 16;
private var i:int;
private var j:int;
// Constructor
public function Grid()
[Code] .....
Unfortunately every time the listener function is called by each button, it uses the last two values of i and j, which in this case return 255 for every button.

is it possible to create custom event with variable arguments count? I ask this because currently I use anonymous functions on events with variable parameters count to pass arguments to appropriate function, i.e:
Code:
addEventListener( MouseEvent.ROLL_OVER, function(evt:MouseEvent):void{mTBGp( pX, pY, l_w, l_h, isDone )}, false, 0, false );
addEventListener( MouseEvent.ROLL_OUT, function(evt:MouseEvent):void{mTBGe( pX, pY, l_w, l_h )}, false, 0, false );
and I don't want to do that because of weakReference.
1. From what I know if I set weakReference to true with anonymous function on in addEventListener GarbageCollector will delete them (and indeed I can see that my code stops to work on random, due to GC "kickin in")
2. When i delete my Object with addEventListener( weakReference = false ) the memory used by addEventListener is not freed ( unconfirmed, please elaborate on that subject also)That's why, from My point of view, usage of custom event is best, but unfortunately I use many addEventListeners with variable parameters count so (in above example 2 listeners. one 5 arg, second 4 arg) is there a way to do something like this? To write event that will take x parameters of any type?

I have a game with two joysticks and I use the dispatchEvent command to send the fire button event. What would be a good way to send the number of the joystick to check who pressed the fire button. A bit dirty way would be to save just the number in root or in my main class.

When you click on the button something happens. However it seems redundant to me that in the declaration of myListenerFunction, the event object e of class MouseEvent, actually has to have its data type MouseEvent mentioned.

I need to add in a mouse over event listener for an object, when I'm already over it. If my mouse leaves the object and comes back, then the listener works, but for some reason, when if I just move my mouse around over the object, it doesn't work. Hopefully that is enough to go on without posting code...

My goal with this actionscript is to create a new movieclip for each top-level XML node and include in the movieclip two separate textfields, an image, extend the movieclips to two row if necessary, rotate each movieclip differently depending its parity and add a hover event based on the movieclips instance name. I have achieved each goal except for the hover bit. The reason I cant access the instance name outside of the for loop is because the instance name only lasts for duration of the loop. Here is my current code (at pastie address).I have extensively searched the interweb to try and find a solution, but nothing has worked.

I have recently moved from AS2.0 to AS3.0 and I am trying to get to grips with event handling. I am managing for things like key presses and mouse clicks
I am successfully tracing a string as either "login successful" or "login unsuccessful" from a PHP file on a local host and it traces as working in my Login class. Now I want to listen for the "login successful" string, currently tracing in my Login class and if it works, call an EventHandler in my Main class which will execute the next step.
Here's my code so far
PHP Code:
private function onLogin(e:Event):void
{
var loader:URLLoader = URLLoader(e.target);

I am trying to create a drag and drop activity, and I would like to use an array for easy reusability.I'm new to as3 so I've been adjusting my old as2 code. I am using a component for each of my drags and most of it is working well.My problem is with the event handlers. I use the array to populate all of my 'drags' with the information added in their parameters and this works, but when I create my event listeners it seems to only want to move the last item in the array.My drag components are called drag1, drag2, and drag3.[code]

I'm amended a AS2 movie, which is a rotating banner add movie. In this movie there is a button which is always visible throughout the movie. I need to add a onRelease behaviour onto this button, so that it can call a JavaScript function when clicked.
I'm new to Flash, I have done some Flex work, but no Flash. How can I add the onRelease behaviour to the button and have it available through out the movie. I know how to convert the button to a movie clip and add the onRelease behaviour but it only lasts one frame, how do I make available through out?
