ActionScript 3.0 :: Events Reaching 'hidden' Objects
Aug 13, 2009
I've made a class which dispatches a string in order to switch languages on a site that I'm working on these days.The objects that should listen for this event type (let's call them targetobjects) are located inside some objects that are located in some objects (3 levels).[code]model to reach the targetobjects I have to make an addEventListener and handler function on the stage, the grandpa object and the father object.Could it be a way to make the targetobjects listen for the LanguageEvent.LANG_CHANGED by themselves?

I'm working on a Flex 3 app, implemented in Actionscript 3 and MXML, that includes an embedded video player, which is essentially a black box--I load it as a SWF from another site on demand, and I don't have access to its source code. It does, however, inherit from Sprite.The problem is that, when focus is on the Flash app, the video player is somehow receiving and processing keyboard events, even when the player itself isn't in focus.So when users are typing text elsewhere in the GUI, if they hit the space bar, the video pauses.
I've tried intercepting key events in the Sprite's parent, and setting tabEnabled = false, tabChildren = false, and buttonMode = false on the Sprite, but nothing seems to work. It's as if the Sprite is getting keystrokes through an alternate Event path.how I can prevent the player from receiving keyboard events or input events entirely? It's fine with me if no input events reach the player, since I've implemented my own,separate video controls.

I have two movie-clips, one is small-box and another is big-box .Both are rectangular shape. Small- box has an index 0, and big-box has an index 1. Their x,y are same and big-box being big in size gets hide small-box. Now the problem is the listener attached to small-box does not fire as big-box is on the top of small-box. what would be the way to get listener fired when click on small-box area??

I want to make the clown dance when he catches a hat (I have a tween for that) who otherwise will be simply standing, Basically I need to animate objects on certain events and then stop, I see so many game makers doing that, I know nothing about it, tried a lot on my own but with no success

So, events bubble up the display list. That's great if that's what you want. But what if you have objects on the stage that are not related that need to listen for events from each other? A simplified example:
var objA = new ObjA;
addChild(objA);
var objB = new ObjB;
[Code]....
Object B can listen for events dispatched by object C. But I also need object A to listen for events dispatched by object C. Also, these objects are created in different classes so I can't hard code references to each other.

I wrote a code for handling google maps in a multi touch table. On the map itself, I have a sort of button that, if touched, makes a tool bar show up. On the bar I have a slider and a button, both of them activated by touch events. My problem here is that when I touch objects on the bar, the touch event pass through the bar and it is fired also on the map below, making my map move. Uff, this is very annoying.

How can I make a mouse event ignore, or skip over another object? Say I have a small Sprite on a Large sprite, I want it to act as if the small sprite isn't there, and pass the mouse events directly through to the larger sprite behind it. I've been searching for this for a while and have tried various things but no avail.

Im creating a game. When the current game has finished, I thinking to do this:
removeChild(game)
game = null
then
game = new Game()
Doing this way, it automatically removes the games object instances? It automatically removes the games object instances events? That would be an easy way to restart the game, if yes for both questions.
Can I do like that, or I have to remove all objects and events manually?

When dispatching events in as3 I always have to extend class from sprite, or movieclip, but when I don't have display objects I don't wont to extend to sprite or movieclip. What is the most light class that I can extend, I mean no display object, and still do use event dispatching?

Is this at all possible? I just finished re-building my entire portfolio site in AS3 because I can't change the frame rate for loaded content in AS2. Now I find out after completely rebuilding this thing that AS2 content gets stuck in Flash Player 9's memory and won't erase on Loader.unload. All my work from years back is in AS2.

I came to the point where I need to communicate between 2 objects (let's say Tank and the Cannon). It is tile game, and when the Tank approach specific tile I need my Cannon to shot the Tank. When Tank gets that specific tile I want to dispatch some custom event and have listener in Cannon class body to make the shot happen. Other way I would have to check in ENTER_FRAME loop (inside Cannon body class) if the Tank touched tile that runs the Cannon shooting - but this is not elegant and efficient. The issue is complicated by the fact that the Cannon and Tank are added to the Engine (document class) and can't simply hear for each other, because they seat on the same level in display list.
Initially I could addEventListener to the Engine, but this way my document class would enlarge to the XXL size (all listeners functionality, all methods for game etc). What I would accomplish is to have event listener in every Cannon object (defined in body class) listening for Tank's dispatching the event. I saw some 'Centralized Event Manager' article in the net, but can't download full classes [url]...

How do I listen to an event dispatched from non-display-list concrete objects which are created by a singleton factory class?
An example would be where I want to create tweens for objects using a TweenFactoryClass. In my Main.as class I have this:
ActionScript Code:
TweenFactoryClass.instance.tweenMe( myClip, 200, 200 );
then, in my TweenFactoryClass.as, I have:
ActionScript Code:
public function tweenMe( clip:DisplayObject, xLocation, yLocation ):MyTween
{
var tween:MyTween = new MyTween();
[Code].....
I don't know where I should add the listener to be able to hear that event that was dispatched from the MyTween class.

i have 2 sprites on stage. bottomSprite is added to the display list first, followed by topSprite. topSprite partially covers bottomSprite.i've added an event listener to bottomSprite for MouseEvent.MOUSE_MOVED notifications to simply trace the mouseX and mouseY coordinates. however, the notification doesn't work for the parts of bottomSprite that are covered by topSprite.
var bottomSprite:Sprite = new Sprite();
bottomSprite.graphics.beginFill(0x666666, 0.5);
bottomSprite.graphics.drawRect(150,150, 150, 150);
bottomSprite.graphics.endFill();

I want to handle the mouseevents for all the sprites on the stage including the one those are hidden behind (or overlapped or occluded) and the main condition is that I want to handle the occluded sprite (that hidden behind other sprite). example, say I have sprite1 and sprite2 on stage and I want to start drag whenever i click on the sprite and stop drag after another click.
This can be done easily, but the problem and my main requirement is that if I drag the sprite1 and drop it exactly on top of the sprite2 then sprite2 will be hidden behind the sprite1 I wont be able to drag the sprite2 without moving the sprite1 first. if you have played zynga's empires and allais game on facebook, it is handled seperatly, it is how it works in that game, the mouse event is triggered on the sprite behind the overlapping sprite, if you have two sprites overlapping one sprite than the mouse event is triggered on the sprite which is last and not the one in front irrespective of whether there is only one sprite overlapping or two or three and this happens to irregular shaped sprites (not just rectangles)

I found this snow script on the web that I would like to use but I don't know how to turn it off.
It starts working when I load the script into frame 1. Then I would like for it to run 150 to 200 or so frames and then I would like for it to stop without using any type of button. I would like for it to just stop automatically after reaching the last frame. A simple stop(); in the last frame doesn't work.
Code:
// max number of snow flakes on screen at once
var nMaxFlakes = 100;
// fastest speed that the snow flakes fall

i have a rectangle named(p1) with w:250 h:400 and a other rectangle named(bs) same width and height , registration point is at the center right. when i click on p1 ,p1 will fellowing my mouse and the p1 rotation is depending on the bs width and height.[code]okise now my intention are , when i release the mouse ,p1 will go move back to the (bs) registration point and on the way to the registration point it will rotation++ to 90 degrees.when reached bs registration point it will become 90 degrees.if my now my p1.rotation is 135, when i release mouse , p1 moved back ,rotation will depend on the distance back and rotation to 90 , like 133 ,125 ,110, 90.

My idea is for a movieclip to flip horizontally when reaching an _x point, which is 225 (it should be half the stage). Now, I know about _root.movie_clip._xscale, and I've tried it, but it didn't work. Here's my code:
onClipEvent(load){
if(_root.poke._x=-225){
_root.poke._xscale=-100;
[Code].....
And I'll upload the .fla for you, so you can see what the problem is.

is there a way to reach the stage (the main time line) from ANYWHERE.In AS2 it was _root...The aim is : I want to add on stage an MC from within a class. As expected, addChild(mc) doesn't work, it adds the child to my class, not to the stage. So : is there any stage.addChild(mc) or MainTimeLine.addChild(mc) or anything like this ?The other way is to add the class on stage addChild(MyClassName).

Basically I have a MC called 'plane3.' Inside that MC is another MC called 'plane2.' Inside 'plane2' is an animation on frame 5.(inside the MC 'plane3' the MC 'plane2' is on a classic tween going side-to-side from frame 1 to 99, once it gets to frame 99 the code gotoAndPlay(1); makes it go on loop back to the beginning)My question is how would I go about: when you click 'plane3' it lets the tween continue playing until frame 10, then on frame 10, it gotoAndPlay (100); in the same MC and ALSO plays frame 5 from inside 'plane2'

What I'm trying to do is: When this button is pressed, whatever is in the current news_Clip movieclip goes to frame 71 and plays till it reaches the end of the outro animation which is frame 101. When it reaches frame 101, I want to load a new swf into news_Clip. Using the above code, the contents of news_Clip does its outro animation but the new SWF is not loaded into it after reaching the end. I've been screwing around with this for the past 7 hours and can't figure out what I'm not doing or doing wrong.

I am new to ActionScript 3.0. I am trying to create a button that will jump ahead to a specific frame, let the animation run, and then stop before reaching a specific frame. I have the first part working:
button1.addEventListener(MouseEvent.CLICK, buttonHandler);function buttonHandler(event:MouseEvent):void { gotoAndPlay("25");}
Once I get to frame 25, the animation will start. But I want to stop the animation at frame 49. How would I do this?

On MouseDown I start a repeating timer to position the Scrollbar-Button(Slider).When it reaches minimum/maximum it jitters (switching between min/max and stage.mouseYŚ)
How can I prevent that?

I currently have an over, out and click event for 8 different objects. The over and out events are identical for each (tween expands object and then shrinks it back for the out state).I have previously asked for an easy way to declare those events, and now I was looking for an easier way to handle them.
Here's my code:
//-----------GARAGE
function growGarage(e:MouseEvent):void{
scaleTweenX = new Tween(map_garage, "scaleX", Elastic.easeOut, 0.648, 1, 0.5, true);
[code]....
I've tried using a single function and then using "this" as the object of the tween but that expanded the entire stage.

I'm making a game. Rings are spawned at an interval (attachMovie) and pushed into an array. I need my character (on the root) to hitTest something inside of the clips in the array, because I have a motion tween with easing inside of my clip (up and down motion).
This is what I would think I would do to hitTest the array (assume this is in a for loop):
array[i].inner.hitTest(_root.char._x, _root.char._y, true);
It doesn't work. I can't access the inner clip if it's in an array.

Just wanted to ask if there is any advantage for either using mouse click event or touch tap events, when writing apps for mobiles or tablets (for the iphone especially)?
I know that both of them should work fine, but in term of performance, is anyone better? Are there any things I should be aware of when choosing either?
By the way am using actionscript3 to implement the app.
