ActionScript 3.0 :: Reference A Clicked Object From An Event?
Feb 22, 2009
So ive made the switch from AS2.0 to 3.0, and like many fellow casual flashers, I'm having a bit of a tough time
I understand that below, the first trace works because the mouse event comes from the clicked object, and that the second produces an error because the ENTER_FRAME event is attached to the stage, so e.target is the stage. i realise i can attach the listener to the obj, but i need it on the stage for what im doing
How can i reference the clicked object from run() ?
I have a MovieClip. It represents animation of jumping monster. For clearness, let's pretend there are only 2 frames: the first one occupies top left rectangle (x = 0, y = 0, w = 70, h = 70) and the second one occupies (x = 100, y = 0, w = 70, h = 70). So monster jumps from left to the right. And position of MovieClip itself is constantly = (0, 0). I'd like to fire some event when monster is clicked by mouse.
For some reason, I have stage mouse listener, not monster mouse listener. I wrote this code: stage.addEventListener(MouseEvent.CLICK, onClick); private final function onClick(e:MouseEvent):void { const clickPos:Point = new Point(e.stageX, e.stageY); // having monster:MovieClip, how do I check hitting it? [Code] .....
I am new to AS3 and to writing classes, but have the following in my class to change the alpha of my button. How do I reference my button in btnOverAction, so I can set its alpha? Is there a way to reference the object the event was called on? I am calling the method to set up multiple buttons like this:[code]
I'm new to AS3 and I was making a game of chess. Basically whenever you click a square with a chess piece, I assumed it would be like java, and you'd be able to create an "ActionListener" that would pass a reference to a square that was clicked.
My question is this: How can I access this square object that was clicked in my array?[code]...
I have a page that I'm working on that works great except I keep getting an "Output" message stating: TypeError: Error #1009: Cannot access a property or method of a null object reference. at StillFrameFoto_fla::MainTimeline/portfolioOut() I'm pretty sure I just need to get rid of my button instance, but I don't know how. I have my buttons on frame 1 and I want them completely gone when it moves to frame 2. Here is the code for one of my buttons on the first frame:
I seem to be having a recurring problem attaching events to a button i have created within 2 other movieclips.I get the following error:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
So it looks like it can't find the button, in order to attach the event listener. The question is why? I am attaching a similar event to a button on the main timeline and that works fine. So it looks like a scope issue, but I am referring to it properly.
I normally write javascript code, so I wonder how to do this. In JS "Microsoft IS" you'll write code like this:
document.onclick = func; function func() { var obj = event.srcElement; //And there I have reference to the object; }
The graphic designer creates flash drawings and then converts whatever objects to movieclips. Then passes them over to me. All these "mc" need the same action applied to them. So I don't need to know how many they are or their names.
I'm working on [URL] and I am using a small swf over the milk carton on the left. I use it to make it look like text being entered is on the milk carton. So its just a textfield and a button.
When the user clicks in the text box it clears and allows typing. This is good. This is the part I'm stuck on: If the user changes their mind about typing and clicks somewhere else on the screen (outside of the swf) I want the example text to return and the text cursor to stop flashing.
I'm making a point-and-click game in Flash and the goal of the game is to click on the right objects in a room. Say, if the main character says 'find my chair', and the player clicks on the chair, it's the good object and an audio file plays. If the player clicks on a spoon, it's the wrong object and an audio file plays. My question is: how can I do that in Flash (in ActionScript, right)? I've made a different layer for each object.
Environment: Windows 7, Internet Explorer 8, Flash ActiveX 10.1.53.64, wmode=transparent
Just wrote a small test page that you can load in IE and Firefox or any other Browser.
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml">

So clicking any colored shape should produce an alert (except for the green one in IE, not sure why but I hope that's off topic and not related to my issue).
Clicking the Flash container in Firefox will work Perfectly fine. You should get alert boxes in this order containing: span, div and body. Flash bubbles the event to the HTML. But this is not happening in IE.
So why is Flash in IE not bubbling events to HTML?
Edit: As mentioned by Andy E this behavior can also bee seen in Google Chrome which to my knowledge is not using ActiveX to embed the flash movie into the page.
so i have an event listener a mouse click in a movie clip name "em_contact" i also have an event listener after an animation plays out on an object called contactbtn_mc, How do i tell Flash once em_contact is clicked dont listen for that event any more?
my code is below em_contact.addEventListener(MouseEvent.CLICK,gotocontactanimation); function gotocontactanimation(EvntObj:MouseEvent):void {
i have a tree component that dispatches an itemOpen event. When the black triangle next to the yellow folder is clicked, that folder opens to expose its children.
Is there anyway to know the index of the open folder? there is a rowIndex property in the target property of the openItem event that stores the index but it is not accessible.
I have an itemRenderer custom component inline of my DataGrid component. I need to have an event fire in the containing class (at the same level as the DataGrid) when the checkbox is checked or unchecked (in the itemRenderer component). How would I do this?
I've got a canvas within which I have a list. The renderer for this list calls upon a "Text" field, with the "link" element of this field set to a function. The "htmlText" of the field is set dynamically to a mixture of words and links. Basically the function checks to see which tag within the htmlText has been clicked and performs an event accordingly.However, you have to click the link twice for anything to happen. Whilst debugging the code I noticed that the function referenced by the "link" element isn't actually even called until the 2nd click.
I have a problem and I have potential solution. But I wanted to confirm if there is an easy and simple way to solve my problem.App type:Isometric Game.Problem statement:I am loading images in my flash app and have mouse events attached to them.The images I load are prop images like vehicles, trees, buildings etc., and all of them are transparent.Example: Red ball asset (please ignore the yellow background which I applied to describe the problem)If I click on the actual image area (colored in red), then every thing works perfect.I don't want to trigger mouseevent when I click on empty image part (or transparent area, which I have shown in yellow color)There is one way I know by creating masks in flash. I don't want to do it unless that is the final option left because I load image assets instead of flash assets and I don't want to create a new mask asset for all the assets.There is another method I was going to adopt by using getPixel method of Bitmap.
But there is another problem with this method.I might be able to ignore the click event when I click on the empty part of the asset but if there is some other asset is behind the image in the same location, then I need to process the click event for the occluded image.Well, thinking of solution to this problem takes me to the getObjectsUnderPoint where I can scan the occluded assets
have one mc called mc1, and when the mouse cursor is over it, mc2 is sent to a certain frame and the _alpha set to 0. The problem I have is that when the user continued with the onPress (pressing the left mouse button) after the cursor goes outside of that mc1, mc2 does not become invisible and what I need is to do that, when the user goes out with the cursor of the mc1, the mc2 becomes invisible even if the left button of the mouse is pressed. And now don't detect the onRollOut if the button of the mouse is pressed.
I have problem with accessing object created by function imported from another package. I have 2 packages DragDrop and UserInterface. In UserInterface I create methods for buttons and later add them in DragDrop . I make it in two different ways: One(this one works):
I am writing some codes inside a movieclip but I want to activate a mouse over event from a parent object since there is a removeEventListener method that delete the the event!Is there a way to do it in actionscript 3.0?
I got a reference to an arrayCollection and add event listener like this: collection.addEventListener(CollectionEvent.COLLECTION_CHANGE, onCollectionChange); That's fine. Now some other component does have the same reference and is adding items to and removing items from that collection.
Each time the handler is called: private function onProjectPersonsChange(event:Event):void { if (event.kind == CollectionEventKind.ADD) { //do something } else if (event.kind == CollectionEventKind.REMOVE) { [Code] ..... Why the removed item is not in 'items'?
this piece of code is being placed inside a swf which is then being placed inside a mxml swfloader. The ProductDesigner is the name of the application and the selectRed is a HSlider mxml component. The error that I receive is that "Access of undefined propertyProductDesigner" in the Flash CS5 when testing the swf. Yes I am able to pick up the intellisense to know that it knows that there is a ProductDesigner in the whatever it's called.
private function ChangeColor(event:MouseEvent):void { var red:uint = ProductDesigner.mainTabs.tabContentColor.selectRed.value;
I have a project with 15 dynamically created MovieClips on. The clips are images loaded from XML.As each one is loaded I assign an id to it. screen.id = [i];Now normally I would add an event listener to trigger each of these to "Do Something" but I want it to be an automatic process. So I have set up a function to create a random number between 0 and 14 with the idea that I can use the number to help reference the MovieClip with the id of the randomly generated number...But I don't know how to go about this Something like...
Code:
Select allprivate function randomNumber(low:Number, high:Number):Number { var low:Number = low; var high:Number = high;
tarting a script to make my object move to the coordinates of where i click on my mouseand if possible i would like to make it animate to each coordinate like its moving there not all of sudden jumps there when you click somewhere.

I want to pass the search object to the result method (onServerResponse) but if I do it in a closure it gets passed by value. Is there anyway to do it by reference without searching through my array of search objects for the value returned in the result?
I'm fairly experienced with Flex 4, but I still haven't needed frameworks yet (I like to do everything myself) and don't want to use them either, I know it's advantages and have learned how to use one of them, but still, no.
How can I dispatch an event in the main application and have a component inside a popupmanager to react to that event? All this dispatching the event within the main app and NOT aiming it to the popupmanager or the component instance, I want to be able to fire the event and not care about who gets it or if anyone reacts to it at all so if that is possible then I wouldn't care about keeping track of said popups.
I already dispatch an event from the component and receive it in the main application by bubbling the event and therefore being agnostic of each other, now I want it backwards.
