• How to best manage multi-frame MovieClips with classes?

  - by Arms

  After switching to AS3, I've been having a hell of a time figuring out the best way to manage MovieClips that have UI elements spread across multiple frames with a single class. An example that I am working on now is a simple email form. I have a MovieClip with two frames: the 1st frame has the form elements (text inputs, submit button) the 2nd frame has a "thank you" message and a button to go back to the first frame (to send another email) In the library I have linked the MovieClip to a custom class (Emailer). My immediate problem is how do I assign a MouseEvent.CLICK event to the button on the 2nd frame? I should note at this point that I am trying to avoid putting code on the timeline (except for stop() calls). This is how I am 'solving' the problem now: Emailer registers an event listener for a frame change ( addEventListener("frame 2", onFrameChange) ) On the 2nd frame of the MovieClip I am calling dispatchEvent(new Event("frame 2")); (I would prefer to not have this code on the frame, but I don't know what else to do) My two complaints with this method are that, first I have calls to addEventListener spread out across different class methods (I would rather have all UI event listeners registered in one method), and second that I have to dispatch those custom "onFrameChange" events. The second complaint grows exponentially for MovieClips that have more than just 2 frames. My so called solution feels makes me feel dirty and makes my brain hurt. I am looking for any advice on what to do differently. Perhaps there's a design pattern I should be looking at? Should I swallow my pride and write timeline code even though the rest of my application is written in class files (and I abhor the Flash IDE code editor)? I absolutely LOVE the event system, and have no problem coding applications with it, but I feel like I'm stuck thinking in terms of AS2 when working with mutl-frame movieclips and code. Any and all help would be greatly appreciated.

• Flex 4 itemRendererFunction problem.

  - by michael

  This is a Flex 4 application: I have created a list as the following: <s:List id="previewList" horizontalCenter="14" verticalCenter="-112" itemRendererFunction="listItemRendererFunction" click="controller.previewListClickHandler()"> </s:List> And I have the itemRendererFunction: public function listItemRendererFunction(item:Object):ClassFactory { var cla:Class = SimpleItemRenderer; if( item.save == true ) { cla = ColorItemRenderer; } else { cla = SimpleItemRenderer; } return new ClassFactory(cla); } The application works fine if the listItemRendererFunction is inside fx:Script. However, when I put the listItemRendererFunction into a class and change to the following: itemRendererFunction="controller.listItemRendererFunction" in the List component. If I run the application, I get the " Error #1009". Please advice how to fix it.

• Confusion over manual/automatic sizing of Flash Sprite Objects

  - by John

  If I have a custom class subclassing Sprite and it draws some simple objects, how does this work with respect to the Sprite.width & Sprite.height properties? It seems I can draw (for example) a rectangle of any size, bigger than the Sprite size. Similarly if I set the width/height properties, what happens to the content already drawn? As a use-case, I might have a stick-man which is drawn as a set of lines, I want to set the man's height and the rendering is scaled to this. Are there any issues with width/height being auto-calculated or am I misunderstanding what these properties actually mean?

• Unreachable, existing variable

  - by Oden

  I'm new at as3, maybe thats the reason why i don't understand, why the setInterval causes an error. <mx:Script> <![CDATA[ import flash.utils.setInterval; import mx.controls.Alert; [Bindable] public var MyInt:int = 500; setInterval(function():void{ ++MyInt; },1000); ]]> </mx:Script> I have a label where the value of MyInt gets visible, the bind works perfect, i've tested it several ways, and i i create a button it grows the number, but if i use the setInterval function i get an error: Access of undefined property myInt. Why? What does cause this? Please explain it, so I can avoid errors like this. Thanks

• Mask image does not appear on the screen

  - by Ponty

  I have imported to the library two images and have given them the custom class names MaskImage and MaskedImage. Then i write the code: package { import flash.display.*; public class MaskDemo extends Sprite { // Properties private var sprMaskedImage:Sprite; private var sprMaskImage:Sprite; private var bmMaskedImage:Bitmap; private var bmMaskImage:Bitmap; // Constructor public function MaskDemo() { do_magic(); } // Methods private function do_magic():void { bmMaskedImage = new Bitmap(new MaskedImage(0, 0)); bmMaskImage = new Bitmap(new MaskImage(0, 0)); sprMaskedImage = new Sprite(); sprMaskedImage.addChild(bmMaskedImage); sprMaskImage = new Sprite(); sprMaskImage.addChild(bmMaskImage); sprMaskedImage.mask = sprMaskImage; this.addChild(sprMaskImage); } } } But it does not appear anything on the display. Any ideas why is happening that?

  - by buzzer

  I'm having a problem in flex 3 where if a static const I have defined is used as the parameter to a function call within binding tags I get a "1120: Access of undefined property NodePropertyMatrix". _propMtx is a ArrayCollection. <mx:HBox visible="{_propMtx.getItemAt(NodePropertyMatrix.srcParent)}"> Above code throws the error, but the following code does not <mx:HBox visible="{NodePropertyMatrix.srcParent}"> NodePropertyMatrix is an AS class as follows: package model.constants { import mx.collections.ArrayCollection; public class NodePropertyMatrix { public static const srcParent:Number = 0; } } Anyone know what is wrong here?

• Smart way to execute function in flash from an imported html (or XML) plain text

  - by DomingoSL

  Ok, here is the think. I have a very simple flash program code in AS3, inside this program there is a dynamic textfield html capable. Also i have a database were i will put some information. Each element in the database can be linked to other. For example, this database will contain tourist spots, and they can be related with others in the same database. Ramdom place 1 This interesting spot is near <link to="ramdo2">ramdom place2</link>. And so, so so... The information in the database is retrived by the flash application and it shows the text on the dynamic textfield. I need somehow to tell my flash application that have to be a link to other part of the database, so when the user click the link a function in flash call this new data. The database is a simple Mysql server, and the data is not yet in there, waiting for your suggestions of how to format it and develop the solution. Im a php developer too, so i can make a gateway in PHP to read the MySQL and then retrive some format to flash, an XML for example.

• Looking for ideas on automatically arranging a set of objects (furniture) in a virtual room in AS3

  - by raf

  First of all, I don't want to visually arrange 3D models dragging them with the mouse, all I want is: Given a room of certain dimensions (L,W,H) and given a set of elements like beds, chairs, etc (with L,W,H dimensions, of course) I want to automatically arrange those elements to take advantage of the space as much as I can. So I want to be able to put as much furniture as I can in a given room. At the end I need to represent the arranged items visually, inside the room. My first thought was to use an array of items and sorting it with array.sortOn(["l","w","h"] Array.NUMERIC) and then define a gap between the objects and make the maths to put the objects one next to another, etc. but that isn't a good approach because some items may be placed on top of another ones (boxes of the same size, boxes on top of tables, etc). I really don't have experience on 3D programming, that's why I'm asking for help. Thanks in advance.

• How do I refer to an instance from inside it's own code in Adobe Flash.

  - by matt1024

  In Adobe Flash, I have a movie clip that is added to the stage when the keyboard is pressed. I want it to travel across the screen and disappear once it reaches the edge of the stage. At the moment I use this but the image appears and then stops. Here is my code: addEventListener(Event.ADDED_TO_STAGE,runtime); var c = 0 function runtime(){ while(this.x<800){ this.x += 12; } removeChild(this); } Thanks

• Can I use a string variable to reference a class variable?

  - by rson

  Here's the scenario: I have an external swf file with x number of movieclips in its library that I load into a containing swf. Each MC in the external swf is linked with a class name and referenced on frame 1 as such var unique1:lineSequence1 = new lineSequence1(); the unique1 variable name will match a string variable I create in the containing swf: function initLines():void{ lineLoader = new Loader(); lineLoader.load(new URLRequest("theLines.swf")); //load external swf lineLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, linesLoaded); } function linesLoaded(e:Event):void{ var loadedswf:MovieClip = e.target.content as MovieClip; var initialLines = projects[0].pageid; //projects is an xmllist trace("initialLines: "+initialLines); //returns "initialLines: unique1" lines_holder_mc.addChild(loadedswf.[initialLines]); } I would like to use the initialLines variable as the reference to unique1 instead of hardcoding unique1 into loadedswf.unique1 to reference said variable in the loaded swf.

• using html text in as3

  - by vincent

  Hello, i'm having a bit of a question, I have some newspost from my database. But there are tags in it and some tags aswell. My questiion is how i should go about it to get the newspost showing as it should be. The images should get shown instead of the tags etc. I know i'll have to work with a loader to use the images but how would as3 recognize them? Is there anyway i could use htmltext or something so as3 knows automaticly where the imagetags are? Also, if i add the image would it be possible to wrap the text around it? So i dont have an empty space next to the image?

• How to create custom MouseEvent.CLICK event in AS3 (pass parameters to function)?

  - by fromvega

  Hello, This question doesn't relate only to MouseEvent.CLICK event type but to all event types that already exist in AS3. I read a lot about custom events but until now I couldn't figure it out how to do what I want to do. I'm going to try to explain, I hope you understand: Here is a illustration of my situation: for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, doSomething); } function doSomething(e:MouseEvent){ /* */ } But I want to be able to pass someVar as a parameter to doSomething. So I tried this: for(var i:Number; i < 10; i++){ var someVar = i; myClips[i].addEventListener(MouseEvent.CLICK, function(){ doSomething(someVar); }); } function doSomething(index){ trace(index); } This kind of works but not as I expect. Due to the function closures, when the MouseEvent.CLICK events are actually fired the for loop is already over and someVar is holding the last value, the number 9 in the example. So every click in each movie clip will call doSomething passing 9 as the parameter. And it's not what I want. I thought that creating a custom event should work, but then I couldn't find a way to fire a custom event when the MouseEvent.CLICK event is fired and pass the parameter to it. Now I don't know if it is the right answer. What should I do and how?

• Selecting id of TextArea (despite RichEditableText)

  - by duder

  I'm trying to select the id of a textArea when it's focused in <s:TextArea id="textarea1" focusIn="selectId(event)" /> selectId(event){ event.target.id; } Problem is TextArea is made up of RichEditableText so target doesn't actually refer to TextArea. I've tried event.target.parent.id but still not getting there. Anyone knows how to get to the bottom of this?

• Problem with HttpService POST

  - by Lost_in_code

  I'm trying to send some data to PHP using HTTPService POST but for some reason it's not working. The same example works with GET but not with POST: private function start():void{ var param:Object = {}; param.date = "2010-10-10"; userRequest.send(param); userRequest.addEventListener(ResultEvent.RESULT, result); userRequest.addEventListener(FaultEvent.FAULT, fault); } private function fault(e:FaultEvent):void{ trace(e.message); } private function result(e:ResultEvent):void{ trace(e.result); } <mx:HTTPService id="userRequest" url="http://localhost:8888/api" useProxy="false" method="POST"/> And here's the PHP code: $d = $_POST['date']; echo $d; if($d == ""){ trace("Date not found!"); die(); } This is the error I'm getting: "Error #2032: Stream Error. URL: http://localhost:8888/api" But when I change the method in HTTPService to GET and in PHP I get the result as expected - PHP sends back the date: 2010-10-10 What am I doing wrong?

• How do I programmatically trigger a mx:Button click event?

  - by knorv

  Consider the following mx:Button: <mx:Button click="doSomething()" id="myButton"/> Is there some way to programmatically emulate the user clicking the button? One obvious way to do it would simply be to call doSomething() which would give the same end result as clicking the button. But I'm specifically looking for ways to emulate the click -- that is something along the lines of myButton.click() (if that should have existed).

• Get list of running processes, get active process (and it's application) Flex/AIR

  - by Adam Kiss

  Hello, just a quickie (or maybe not:] ): Is it possible to get somehow list of running applications/processes and, while running in background, check which process is active? Additionally - if somehow, the answer was yes, is it possible to react for change of active window / application react just as if it was Event, or bind to it custom event (e.g. Event.SystemActiveAppChange)? Thank you for answers as well as pointers. EDIT: Due to probable missunderstanding, I mean local applications - on your win/mac/linux machine - I would like to (in process of learning of language) track what apps I use the most, make a little graph maybe? So, the point is: in AIR app, developed in FLEX, I would like to get/list all running applications/processes, as well as which one is active (on user's PC/Mac/Linux)

• Do superfluous calls to addEventListenter("event", thisSpecificFunction) waste resources?

  - by Richard Haven

  I have ItemRenderers that need to listen for events. When they hear an event (and when data changes), they dispatch an event with their current data value. As item renderers are reused, each of them is going to add its callback in set data(value...)and pass the callback function in the event as well as the current data value. So, the listener of the item renderer's bubbling event will set someEventDispatcher.addEventListener("someEvent", itemRendererEvent.callbackListener). This will happen more than once. Does setting the same event listener on the same event for the same dispatcher waste resources? Does the displatcher see that it already has the listener?
