how to make the custom class to pass the information.
My question is this: Why did Adobe not create such an event in the default API? What downside is there to using this method as the main way to pass information between MVC style components? Since they made special events for everything else, and its such a common practice, surely there must be some reason why it wasn't done.
I am having trouble wiring up an event listener to a fl.transitions.Transition.
Is it possible to somehow view all the events an object fires? That way I could check I am using the correct event (and possible view better ones to use).
Does anyone know if it's possible to listen for all events fired from an object without having to specifically listen for each one?
View 5 RepliesI am trying to create an object that is handling the events of different objects. The object is created in the 1st frame of a code layer:
ActionScript Code:
var gImageEdit:ImageEdit = new ImageEdit( imgAction, movImageFront,
movToolbar.btnZoomInImage, movToolbar.btnZoomOutImage, gZoomSound );

I'm trying to make a scrolling slideshow (as long as the mouse is on top of the the obj1, obj2 will move up).
What is the event that will allow me to do that? Mouse_Up will only be activated if the obj1 is clicked =(.
obj1.addEventListener(MouseEvent.MOUSE_MOVE, mouseMove);
function mouseMove(event:MouseEvent){
obj2.y-=1;
}
I'm trying to create events for each object on the array, that i create, like this:
function createObject()
{
ObjectToHandle[counter]=new MovieClip();

I have problem with clearing memory in my game because of eventListeners, garbage collector not clear my objects with events, because events points them when objects are removed from scene. Is there any way to clear events connected to object and his childs? (game create a lot of objects and put diferent listeners if necessary, but because there are also libraries which are created by other programmers I cant just make list of events to clear) Even clar whole scene will be sutable for me if it will destroy all events, because its big problem and game close to beta -.- the only thing I cant do is close flash window
View 5 RepliesI'm still trying to get my head around the best way to structure event flows. Someone made a lot of sense by telling me that contained objects should be decoupled from their parent containers so they're reusable between containers. Instead of calling their parent's function, they dispatch an event. Sensible! I recently myself in the awkward-feeling situation of dispatching an event on a contained object, from its parent. It seems more intuitive for an object to be the one dispatching its own events. Maybe I'm bordering on breaking the Law of Demeter? Example of what I'm doing: child.dispatchEvent(new ChildEvent(ChildEvent.IM_BEING_A_CHILD)); Am I correct in feeling strange here, or is it a normal thing for one object to dispatch another object's events?
View 1 RepliesI have some Movieclips that play sounds on mouse over, and end the sound on mouse out. That has worked fine for me.I just implemented some tween animations on the rollover (they enlarge), but now I am having problems because the animations cause multiple mouse over/out events.
View 4 RepliesI am working on an flash application that requires that all user interaction are stored in a database. The application will have thousands of lessons and needs to keep track of how long each user views lessons and scenes with in the lessons.
I would like to come up with a good solution on how to accomplish this with out having to send a call to a serve side object every few seconds. I could store the data in an as3 object and pass it when the user finishes a scene or exits out of a scene. However this would not work when a user just closes the browser. Maybe I could tie in some JavaScript.
I am designing a physics container. Don't worry, my question is not about the physics. Here is part of my code. Noticed that I have a SetStyle statement there. I realized that if I don't have that line, the MOUSE_DOWN, MOUSE_UP events won't work. If I do have that line, then those events works fine.
Code:
package components {
import flash.events.MouseEvent;
import spark.components.SkinnableContainer;
public class Test extends SkinnableContainer {
private var mouseDown:Boolean;

I have a movie, which on the click of a button will load a child swf.
The child swf has code which adds events to the stage object.
the child also accesses properties such as stage.stageWidth
When the child is ran on it's own all is fine, though when it loads within the parent movie i receive the error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.at Home()
"Home()" is the name of the document class in the child SWF.
a) access the stage from a child swf
b) add events to the stage from a child swf
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?
I have created a FLV video player using the AS3 flash.media.Video object (not the FLV playback component) and I am trying to listen for meta events and Cue Points embedded in the FLV video but I am not receiving any when I trace the movie. The cue points are not being created dynamically, they are in the FLV video.
Video embed code:
// Initialize net stream
nc = new NetConnection();
nc.connect (null); // Not using a media server.
[Code]....
Is there anything I am missing have wrong to capture events from my net stream?
I'm drawing an arrow as a <s:Path> and I need to get notified when the mouse is over it. How can I do that?
The arrow is an element of a Group container.
I tried registering for MOUSE_OVER events for both the container and the arrow and none seem to fire...
Let's assume i have a class MyDisplayObject extending a Sprite.
I have placed several instances of that class on the same place on the stage (they are not nested) and each of them have a mouseclick listener defined within the class.
What i want is, that if i click on that area, where these objects are, that each of them triggers the mouseclick event...by default only the topmost object triggers the event. I would prefer a solution that i can implement within my class MyDisplayObject instead of iterating all children on the stage and triggering each event manually.
I have numerous objects, many of them are stored within other objects (and overlap in physical space). As I zoom into an object, it begins to fade away. At the moment it begins to fade, I load in the child object (or create a child object if one doesn't exist). I want to turn off the parent object's ability to respond to most events. The exception is the scroll wheel, which needs to be sent to both objects simultaneously so that the parent can continue to fade out as I zoom farther in. Try as I might, I can't find a way to tell Flex "hey, for right now dispatch these types of events ONLY to this object." I either end up with event dispatch stack overflows from trying to manually redirect the events, or I get events that don't activate at the correct time or on the correct object. What can I do?
View 1 RepliesI have objects that the user can click&drag. They're PNGs, mainly rectangular, no problem till here.But I then had to put an L-shaped object (a PNG with a lot of transparency), so i've made a movieclip with an shape with the same L shape than the png, and use it as its hitArea:
shape.visible= false;
shape.mouseEnabled= false;
obj.addChild(shape);
obj.hitArea= shape;
This works PERFECT, the mouse events respond as expected, and I can click on objects that are below/above the transparent area of the png/object.All objects are inside a Sprite called playgroundLayer1. The issue comes when I take the L-shaped object and put it on another Sprite (playgroundLayer2), that is above the playgroundLayer1.I this case, I can click&drag on the L, but no object below the transparent area of the L receives mouse events.

So when I navigate out of this movieclip once the function home1 is fired, I get the following error TypeError: Error #1009: Cannot access a property or method of a null object reference. at home_fla::mc_content_13/follow() I know it is the function looking for that mouseThing_mc that is not there.
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.
I have an animation that I want to start when clicking on the flash window. However, I've also have some buttons on the stage. If I add an event listener for MouseEvent.CLICK on the stage, then it 'eats up' the events and the buttons don't work.
I've tried some tricks, by adding some invisible buttons on top of the real ones, and use the MOUSE_OVER event to selectively enable/disable the mouseEnabled flag for the stage, but didn't work because it complains that the property or method doesn't exist (which I find odd).
I keep getting the following error msg below I would be very happy if some knows the solution to this: Error Msg: 1118: Implicit coercion of a value with static type Object to a possibly unrelated type flash.events:Event Object A dispatches Event as:

I have noticed that using the "addEventListener" and coming back into a frame, I get multiple events tied to the same component.The design I am using jumps to an "I" frame (intermediate) and then back to the "M" frame (main) when the user performs an action.I add event listeners to several components when I enter that M frame. What I notice is that the events seem to stack up for a particular component.
For instance, if I enter M frame, N number of times and addEventListener("click", handleEvent) to a radio button, I get N calls to handleEvent when the user clicks on the radio button. I guess this kinda makes sense but is not what I want. I just want one event of a particular type (in this case "click") to be associated with the a particular component. I get around this issue by removing the event(s) in the I frame. Then they get reinstalled in the M frame. Only one at a time.
So, just wondering about this behaviour. Is there a way to check for the number of events that are currently active on a particular component? Better way to handle adding events?
I am designing a music player using JavaScript (jQuery) and HTML5, with Flash AS3 to fall back. Basically what I want to do is to be able to click HTML control elements and have them interact with the flash in order to play/pause and skip tracks in the playlist (playlist JSON file read by JavaScript, passes file ID to AS3, AS3 reads another JSON file to get URL, then plays audio)
This enables me to only use the Flash to play the audio, thus creating the same user experience regardless of HTML5 browser support. I'm assuming I will have to 'listen' for events in AS3, however any pointers in how to engage these events in JS and react to the events in AS3
LinkeSetFx has its own CollectionEvent, but I don't know how to map the LinkedSetFx event to mx.events.collectionEvent(I want use it in ComboBox). LinkedSetFx is in AS3Commons-collection framework.Here is the url, choose the as3commons-collections-1.0.0.zip, you'll find LinkedSetFx in srcorgas3commonscollectionsfx

Right now all the sounds (78 of them) on my guitar play using the roll_over event but that doesn't give the user much control over what sound is played.
The actionscript im using to play my sounds is this;
for(var i:uint = 0; i < buttonArray.length; i++){
buttonArray[i].addEventListener(MouseEvent.ROLL_OVER, buttonRolledOver);
}
[Code]....
What i want to do is only play a sound with the roll_over event when the left click is held down.
is there a way in action to group to object so when one object is drag across the screen the other object sticks with it, im using flash btw
