I'm currently working on a nav bar but I've run into a questionable situation. There are several links in the menu, and for each i'd like a mouse event on over and on out. Do I have to specify both of these events for each link, or is there an easier way to do it that I don't know about? Can you apply event listeners to multiple objects/functions?
View 6 RepliesI want to group some objects (movie clips) in a way allowing me program an event that applies to all of the objects.To be specific, I want to group some buttons in a video player. If the mouse hovers over any one of the buttons, that button's animation will jump to frame 2. How can I do this?(I figured there is probably an easier way than programming each individual button to jump to frame 2 on mouse over.)
View 7 RepliesI have made an event listener:text0_mc.addEventListener(MouseEvent.CLICK, showMe);showMe is a function, but I need it to call more than 1 function at once i.e. -ext0_mc.addEventListener(MouseEvent.CLICK, showMe1, showMe2, showMe3, showMe4, showMe5, showMe6, showMe7);Each function contains an if statment as below.
function showMe1(event:MouseEvent):void

What I am trying to do is, if a user presses keyboard (key 1), picture 1 should FadeIn and if a user presses keyboard (key 2) picture one should FadeOut and picture 2 FadeIn and vice-versa. With the code mentioned below it works fine sometimes if I am not pressing any other key while it is performing one action but sometimes it behaves weird also. What I want AS3 to do is not to take any action or in other words it should not listen to keyboard until it finishes the opening or closing animation of a picture or any other object assigned to the key.
stage.addEventListener (KeyboardEvent.KEY_DOWN, KeyDownHandler);
/**///keyboard keycode for 1 & 2var key1:uint = 49;
var key2:uint = 50;
var BG1:Image1 = new Image1();

I've had this glitch for a long time, and I've tried several ways to get rid of it, and now that I just recoded everything to see if it was something I did, it's back again! basically, whenever I press space (regardless of whether or not I am listening for a space press [or any key press]), the last function fired by an event listener will run itself again, with the exact same arguments supplied to it in the first time.
For example, if I make a simple button to trace("text"); and take you to another frame. Once you get to that frame you can press Space and it'll trace "text" again! I really have no idea what's causing this, and it doesn't seem to be happening to me in new files. and there's too much code to show you, but I just want to know if anyone has heard of this before or if they have any theories to what's going on.
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 RepliesI am adding a different listener to each button in the menu and there are several menus as well, then each one of those functions adds a different child depending on the button and also pushes several values to the Array list, in this example called objectsOnStage. I will be running this structure function 40 times with each of the highlighted elements changing accordingly.
//Listener and function for Button01
menu01.button01( MouseEvent.MOUSE_DOWN, button01Function);
function button01Function(event:MouseEvent):void
{
[code]....
My original thought was to keep all those changing values in an Array list and run a loop for the function/listener, but I just cant make it go.
I have 2 functions. Each one is being called by a different event listener. Both event listeners work because I am able to trace strings in both of them.. my problem is that i am trying to create a variable that is local to both functions. The first function "working" adds a number to the variable and when the second event listener triggers function "notworking" which retrieves this same variable called "counting" both functions are called automatically by event listeners.. how do I do this? i am stomped!

I've managed to create a button which on MOUSE_DOWN scales its parent object- it works just like windows in your OS, where you grab the corner and can change the scale of the window.
Here's how I've done it, (minus the MOUSE_DOWN listener)
Code:
function scaleDragHandler(event:Event):void {
var mcWidth:Number = event.target.parent.width;
var mcHeight:Number = event.target.parent.height;
[Code].....
However, it throws the error, "Access to undefined property 'scaleMC'" on the removeEventListener line. My thought was to put another listener for mouse up inside the first, but that sounds wrong
fileReference.addEventListener(Event.COMPLETE, uploadCompleteHandler);
private function uploadCompleteHandler(event:Event):void {}
Above is one way to add an event listener in Actionscript. By default the callback function needs to have an argument with name event and type Event. Is there a way to declare this function without any arguments :
private function uploadCompleteHandler():void {}
Edit : It's possible to add an event handler without any arguments in mxml. So one student wanted to know, why isn't it possible to do the same in actionscript?
This is my first real programming endeavor and this is the last thing holding my little project back from being a success.
My goal with this code is to add event listeners to an array of Movie Clips that will drag and drop them on the stage.
Here is the code:
var itemBank:Array = new Array(d1_anim.drawer1.test01.movieClip_1, d1_anim.drawer1.test01.movieClip_2);
for(var i:int = 0; i < itemBank.length; i++) {

I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?
im trying to use a use a code segment that makes something avoid the mouse. My issue is the code requires that iff i have more than one object that i want to avoid the mouse than i need to make a new set of variables for the second object and pretty much copy the code than change the variable names. Thats all great and dandy but i have a couple hundred very small objects that i need to avoid the mouse. is there any way to maybe apply the code to each object with an onclipload maybe?
ActionScript Code:
import flash.events.Event;
stage.addEventListener(Event.ENTER_FRAME, fun);
function fun(event:Event) :void {
[code]....
as you can see the object i want to move requires its own variables and 2 if statements. and i REALLY dont want to have to copy/paste that code over 200 times and make a new set of variables for each object. maybe i could apply the code to the object itself ? but than what would i name the variables?
I'm kind of new to AS3 and I created a blur effect for 6 text object. I got the result I wanted, but I thought there has to be a better way of doing this. When a mouse is over a text, other texts get blur. Now, I had only 6 object what if you have 10s of objects on the stage.[code]...
View 0 RepliesI have a parent SWF (Parent) that handles user navigation between multiple children SWFs (Child_1, Child_2, Child_3). How do I add event listeners to the navigation buttons on the children SWFs so that the user can move laterally between Child_1, Child_2 and Child_3? I can think of two options but can't get either one to work:
1) The parent SWF sets up the event listeners when it loads a child. So, I use a loader on Parent to load Child_1 and in Parent add eventlisteners to Child_1.myNavigationform.myButton.
The problem here is that the Parent is only handing the loader instance and I can't think of how it would drill down to the individual objects within Child_1.
2) Child_1 adds the event listeners to its own objects. This just reverses the problem. Child_1 has no problem accessing its own buttons but when a user clicks them it has no way of accessing methods on parent so that Child_2 can be loaded.
I am creating a site with lots of big scrollable text-boxes in it. Each text-box object contained some text, and two buttons to scroll up/down with. The scroll buttons each had an event listener so the text moved when you clicked them.
These text-boxes were stacked on-top of each other with all except one having an alpha of 0. If I wanted to change which text-box is active I move it to the front and call a small TweenLite animation.
To the left (outside of the text-box objects) I have an object similar to a menu. It also has about 12 or so event-listeners (one for every button).
This turns out cause A LOT of lag an it's very troublesome for my laptop to run it. reduce the number of event-listeners on the stage and also the amount of text-boxes.
What I was thinking was to add the text-boxes using AS so I only have 1 on the stage at a time but I couldn't figure out how to do it. I also thought it might be better to just use 1 big event-listeners and from mouseX and mouseY decide which button the user is trying to push.
In AS2 you could add an onRelease to multiple buttons like this:
Code:
onebutton.onRelease = anotherbutton.onRelease = lastbutton.onRelease = function() {
//do something when either button is pressed;
}
Is there something similar possible in AS3 using addeventlistener? Besided copying the same addeventlistner line for all individual buttons?
I have a movielcip (A) class in which I have used a Tween class effect on a child movieclip (B) scrollRect. The (B) Movieclip in turn has several movieclips whose have tween class effect being executed on thier child movieclips.the tweens are all unique to each movieclip and the event listeners are taken off once completed.This works all well and good in FLASH IDE..My problem arises when I try to view this in a browser on a Windows XP.[code]
What is happening in most cases it that the animation appears to "stick" but i think what may be happening is the listening or removal of the event listeners. The animations are left incompleted.Is there any rule of thumb when using multiple event listeners?[code]the effect disables and re-enables the buttons when its done.... then the listeners are removed.each one with the exception cretes its own unique tween (obviously this is a custom class built as each clip)
I want to make a little game. What I need is to add event listeners to all of Tank objects inside the Battlefield instance. I just can seem to figure out how.
View 1 RepliesI have assigned two event listeners to the same property:
full_loader1.contentLoaderInfo.addEventListener (Event.COMPLETE, fullLoaded1);
full_loader1.contentLoaderInfo.addEventListener (Event.COMPLETE, tweenOut2);
So far it works fine. I am just wondering if there is a hidden penalty that I am eventually to learn about.
In some cases it is important to remove multiple event listeners in order to reduce CPU time.[code]...
View 3 Repliesi have a rookie question to ask and it's how to assign the same event listeners to multiple buttons in as3 instead of having to write out the same code over and over again like so...

listing.home.addEventListener(MouseEvent.ROLL_OVER , butOver)
listing.home.addEventListener(MouseEvent.ROLL_OUT , butOut)
listing.home.addEventListener(MouseEvent.CLICK , released)

I want one PopUp to show up at (a lot) of different instances. And something unique has to happen linked to that instance so my thought is:

etc...

I've created a grid of 3D cubes using modulus, and the 3d cubes are were created from the Math and Flash tutorial. I have set up listeners so when the mouse hovers over a cube it starts to rotate:
private function setUpListeners():void {
spBoard.addEventListener(MouseEvent.ROLL_OUT,boardOut);
}
That works fine.
To begin the rotation of the cube when the mouse passes over it I have used:
private function boardOut(e:MouseEvent):void {
addEventListener(Event.ENTER_FRAME,rotateSquare);
var i:int = 1;
function rotateSquare(e:Event) {
renderView(curTheta+i,curPhi+i);
i++;
}}
I can see why this would be inefficient, as it is running the loop every every frame, and for so many multiple cubes it just lags (very badly). I should clarify, I'm hoping for the rotation to continue indefinitely once the mouse moves off the cube. Here is how I am creating the cubes onto the "grid":
public function FlowerMenu(){
var rowY:Number = 0;
for (var i:int = 0; i < 190; i++) {

Most flash games and interactive animations that use keyboard events are made to respond in different ways to different keys.I am working on games for toddlers, who basically just bang on the keyboard indiscriminately. The trouble I'm having is setting up keyboard eventlisteners (key_up) that each perform different function.We're talking games like: when key pressed, ducky dances; when key pressed, doggy dances; when key is pressed, ducky and doggy go to sleep. I've attempted removing the listener before adding the next one:
stage.addEventListener(KeyboardEvent.KEY_UP, doSomething);
function doSomething(evt:KeyboardEvent):void
{make it do something;

I have 3 frames each with a movie clip called map_mc. Each different map_mc have different objects that call the CollisionDetect class. Heres whats happening. objects from frame 1 will start freaking out when I goto frame 2. How do I remove only the event listeners from objects only on frame 1?
I have been trying this.currentFrame but the problem is that all the objects are inside map_mc on the first frame so no matter what it will always be 1. On the other hand MovieClip(root).currentFrame will always give me the current frame but wont tell me what the objects frame is relative to the stage.What I want to do is have something to this effect:MovieClip(root).this.currentFrame would output that this object is on frame 1 and MovieClip(root).currentFrame will tell me that the stage is on frame 2 so I can remove the listeners accordingly.
I added this code to make a movie clip (gFP) popup when rolled over and shrink back when rolled off:
gFP.addEventListener (MouseEvent.MOUSE_OVER, goToGFPOver);
private function goToGFPOver(e:MouseEvent):void
{
gFP.scaleX = 1.4;

It works, but I have 45 movie clips I want to add this to - way too much code. Is there a way to have the event listeners for all the movie clips go to the same "Over" and "Out" functions?
I would be grateful if anyone could point me in the right direction for this question: I have an event handler that is called by multiple objects onClick - ie, I have several objects which I want to respond in the same way onClick. I was wondering if there was a way of amalgamating all the calls to this event handler into one call: at the moment I have:

So I have an object, generated on each click of the mouse. It's set up as a series of points with properties, with values for position randomly calculated, and set around where the user clicks the mouse. Lines are drawn from where the mouse is clicked out to each of these points, so it kind of looks like a star, but only lines, rather than a solid shape (like those old 50's atom clocks?). So once clicked there's an enter frame event listener on the object so that each of the points 'wobble' (using a randomly generated number) up and down around the original point.
For some reason, I can either set it so that on each new click of the mouse and newly generated object, the last one stops "wobbling" and only the new one does, or each new object moves to where the new object is, and maybe is still wobbling(?), but is underneath the new object. This way has the event.target as a new object in the wobble function, so I think it may be just a case of where the centre point is - i.e. saving the mouse x and y for each object individually, or perhaps I have too much of the setup function code repeated in my "wobble"function?
