is there a way through action script to acquire a button event with parameters....lets say I dynamically load an mc that contains buttons...i want to find the names of the functions those buttons call, upon what event, and included parameters.
View 4 RepliesI 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.
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.
View 1 RepliesI'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'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);

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.
I'm trying and it doesn't seem to like it. I'm guessing it's not possible?[code]...
View 5 RepliesMy 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?
View 2 RepliesHow 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 have linked a movie clipe and creating multiple copies of it through attachMovie().i want to used this enterframe event to change the alpha of all my movie clips from 100 to 0 and viceversa when i drag and drop the movie clip

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 just posted a message asking how to call a method from the constructor which has the parameters e: Event. I mistakenly ticked that post as answered when in reality it isnt. I was told I could add = null in the parameter of the function to make it work, like this:
[Code]...
Is it possible to pass parameters through for instance a MouseEvent.CLICK, or Event.ENTER_FRAME, if so then how?
View 3 RepliesI 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.
View 2 RepliesI 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.
I'd like to know what's the different using global functions and functions with param..Why using params? When the as3 developer uses it?
View 3 Repliesis 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?
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 am trying to make a series of images act like buttons, where each button opens a new browser window with a url of my decision. I have put in the images, converted them to symbols (buttons) and given them an instance name.
Now, the AS3. The following works for me:
Code:
btn_bent.addEventListener(MouseEvent.CLICK, buttonClickHandler_beton);
function buttonClickHandler_beton(Event:MouseEvent):void {
navigateToURL(new URLRequest("http://www.hattingks.dk/Default.aspx?ID=6587&ProductID=9866200&VariantID=&GroupID=vogne"));
}
But I wouldn't want to make a new function for each button. I have tried to extend the function to take two parameters like:
Code:
buttonClickHandler_beton(Event:MouseEvent, www:String):void
I have created a Flash movie which, when previewed in Flash works perfectly. Flash CS4.I have put this code in at the start:
mysitebtn.addEventListener(MouseEvent.CLICK, onMouseClick); function onMouseClick(e:MouseEvent):void { var request:URLRequest = new URLRequest('http://www.example/home.html'); navigateToURL(request,'_self'); }
navigateToURL (new URLRequest('http://www.example.html'), '_self');
and a Stop() action on at the end.
Publish with "Loop" in HTML tab is unchecked.
The Loop button is unchecked in Dreamweaver Parameters.
When you click on a button and the animation is supposed to play foward or reverse based on which year the user is currently on and which they are selecting. Going forward is no problem However I don't know how to link the button event to the onEnterFrame() event so that when I use the prevFrame(), it will play in reverse at the same frame frequency as going foward. This is the code I have now.It goes back to the frame that it's supposed to, but the animation is not at the same speed as going forward. I goes back as fast as the code can loop.
function frm94to93 (event:Event):void{ while (currentLabel != "Frame1993"){ trace(currentFrame); prevFrame(); }
What button event should I use to make the program understands to DO SOMETHING only when the button is pressed/dragged. In my sample code below, I want something to happens only if the button is dragged beyond 200 in y axis. I tried onRelease, onRollOver and onDragOver but still not working

how can I add a button event to the OK button available in the alert box?
1. When the "OK" button in the alert box is released the movie should gotoAndStop("At the specified frame")
to save space for when I upload to a swf hosting site I wanted to optimise my flash file as much as possible. The design is a cube which rotates displaying 4 sides, these 4 sides are individual frames, I have an animation which is in between each section to get to each frame, one where the cube rotates right, one left.there are only 2 animations and previously I had duplicated each animation 4 times with an actionscript "gotoAndStop" command at the end of them. I've tried having a simple .flv file with a complete action as well but the .swf hosts all seem to hate that.I want something similar to:
right_btn.onRelease = function() {
gotoAndPlay(5);
}
[code]....
I am trying to load a video which is in the same folder as the flash file using a buttons but its not loading.
Here is the code I am using:
_root.Cross.onRelease = function() {
_root.gotoAndStop(9);
var nc:NetConnection = new NetConnection();
nc.connect(null);
var ns:NetStream = new NetStream(nc);
Gamevid.attachVideo(ns);
ns.play("gta.flv");};
I am trying to display a button, when a video clip finishes playing - the code i'm running does not generate an error, but does not work either.[code]...
