  • [as3] list cellRenderer

    - by lemon
    I'm quite new with as3 via cs4 so please bear with me. I'm trying to make a phone book type list that displays the users name, cellnumber and possible a delete button. --- Bob 09XXXXXXXXX delete --- Sussie 09XXXXXXXXX delete --- Johnny 09XXXXXXXXX delete --- I've tried making a list and added to it a XML dataprovider <profiles> <profile> <label>Bob</label> ... </profile> It'll then display a list of names Bob Sussie Johnny But what do I have to do in order to get it print like fig 1? I know that it has something to do with CellRender but I can't seem to find any decent examples in Google.

  • Why is there no assertError() function in FlexUnit?

    - by lorennorman
    It seems that most XUnit testing frameworks provide assertions for the times when you want to assert that a given operation will thrown an exception (or an Error in AS3 parlance.) Is there some "standard" way of doing this that I am overlooking, which would explain the absence of an assertError() assertion included with FlexUnit? I know HOW to implement such a thing, and I will probably add it to my FlexUnit (go open source!), but it seems like such a glaring omission that I'm left wondering if I'm just doing it wrong. Anyone have thoughts on this?

  • A* (A-star) implementation in AS3

    - by Bryan Hare
    Hey, I am putting together a project for a class that requires me to put AI in a top down Tactical Strategy game in Flash AS3. I decided that I would use a node based path finding approach because the game is based on a circular movement scheme. When a player moves a unit he essentially draws a series of line segments that connect that a player unit will follow along. I am trying to put together a similar operation for the AI units in our game by creating a list of nodes to traverse to a target node. Hence my use of Astar (the resulting path can be used to create this line). Here is my Algorithm function findShortestPath (startN:node, goalN:node) { var openSet:Array = new Array(); var closedSet:Array = new Array(); var pathFound:Boolean = false; startN.g_score = 0; startN.h_score = distFunction(startN,goalN); startN.f_score = startN.h_score; startN.fromNode = null; openSet.push (startN); var i:int = 0 for(i= 0; i< nodeArray.length; i++) { for(var j:int =0; j<nodeArray[0].length; j++) { if(!nodeArray[i][j].isPathable) { closedSet.push(nodeArray[i][j]); } } } while (openSet.length != 0) { var cNode:node = openSet.shift(); if (cNode == goalN) { resolvePath (cNode); return true; } closedSet.push (cNode); for (i= 0; i < cNode.dirArray.length; i++) { var neighborNode:node = cNode.nodeArray[cNode.dirArray[i]]; if (!(closedSet.indexOf(neighborNode) == -1)) { continue; } neighborNode.fromNode = cNode; var tenativeg_score:Number = cNode.gscore + distFunction(neighborNode.fromNode,neighborNode); if (openSet.indexOf(neighborNode) == -1) { neighborNode.g_score = neighborNode.fromNode.g_score + distFunction(neighborNode,cNode); if (cNode.dirArray[i] >= 4) { neighborNode.g_score -= 4; } neighborNode.h_score=distFunction(neighborNode,goalN); neighborNode.f_score=neighborNode.g_score+neighborNode.h_score; insertIntoPQ (neighborNode, openSet); //trace(" F Score of neighbor: " + neighborNode.f_score + " H score of Neighbor: " + neighborNode.h_score + " G_score or neighbor: " +neighborNode.g_score); } else if (tenativeg_score <= neighborNode.g_score) { neighborNode.fromNode=cNode; neighborNode.g_score=cNode.g_score+distFunction(neighborNode,cNode); if (cNode.dirArray[i]>=4) { neighborNode.g_score-=4; } neighborNode.f_score=neighborNode.g_score+neighborNode.h_score; openSet.splice (openSet.indexOf(neighborNode),1); //trace(" F Score of neighbor: " + neighborNode.f_score + " H score of Neighbor: " + neighborNode.h_score + " G_score or neighbor: " +neighborNode.g_score); insertIntoPQ (neighborNode, openSet); } } } trace ("fail"); return false; } Right now this function creates paths that are often not optimal or wholly inaccurate given the target and this generally happens when I have nodes that are not path able, and I am not quite sure what I am doing wrong right now. If someone could help me correct this I would appreciate it greatly. Some Notes My OpenSet is essentially a Priority Queue, so thats how I sort my nodes by cost. Here is that function function insertIntoPQ (iNode:node, pq:Array) { var inserted:Boolean=true; var iterater:int=0; while (inserted) { if (iterater==pq.length) { pq.push (iNode); inserted=false; } else if (pq[iterater].f_score >= iNode.f_score) { pq.splice (iterater,0,iNode); inserted=false; } ++iterater; } } Thanks!

  • No mic activity with setLoopBack set to false - AS3

    - by Franky
    Trying to figure out why setloopback needs to be set to true for microphone activity to be detected. The problem is the echo feedback when using a macbook with a built in mic. If anyone has some ideas about this let me know. Right now I'm experimenting with toggling gain, depending on activity to simulate echo reduction. Not optimal though. @lessfame

  • Flash AS3 - Display an error if the XML if incorrect

    - by ongoingworlds
    Hi, I'm creating a flash application which loads in some XML which is generated dynamically from the CMS. I want to display an error in case the XML file isn't formatted correctly. When I test this with incorrectly formatted XML, it will just get to the line myXML = XML(myLoader.data); and then just bomb out. How can I catch the error, display a message to the user, but the flash program to continue as normal. var myXMLURL:URLRequest = new URLRequest(XMLfile); var myLoader:URLLoader = new URLLoader(myXMLURL); myLoader.addEventListener(Event.COMPLETE, xmlLoaded); myLoader.addEventListener(IOErrorEvent.IO_ERROR, xmlFailed); var myXML:XML; //--when the xml is loaded, do this function xmlLoaded(e:Event):void { myXML = XML(myLoader.data); trace("XML = "+myXML); } //--if the xml fails to load, do this function xmlFailed(event:IOErrorEvent):void { errorMsg.text = "The XML file cannot be found" }

  • How do you draw a line from one corner of the stage to the other?

    - by George Edison
    I am completely perplexed. I asked this question and it (any mentioned solution) doesn't seem to be working at all. All I want is to draw a line from one corner to the other. Here again is the link to the SWF file I have (it's embedded in an HTML document): test.html Here is the source: package { import flash.display.Sprite; import flash.events.Event; public class Main extends Sprite { public function Main():void { if (stage) init(); else addEventListener(Event.ADDED_TO_STAGE, init); } private function init(e:Event = null):void { removeEventListener(Event.ADDED_TO_STAGE, init); // entry point graphics.clear(); graphics.lineStyle(10, 0x000000); graphics.moveTo(0, 0); graphics.lineTo(stage.stageWidth, stage.stageHeight); } } } It just doesn't work! The line goes from somewhere offscreen to about the middle of the stage. What on earth am I doing wrong?

  • Coordinates in distorted grid

    - by Carsten
    I have a grid in a 2D system like the one in the before image where all points A,B,C,D,A',B',C',D' are given (meaning I know the respective x- and y-coordinates). I need to calculate the x- and y-coordinates of A(new), B(new), C(new) and D(new) when the grid is distorted (so that A' is moved to A'(new), B' is moved to B'(new), C' is moved to C'(new) and D' is moved to D'(new)). The distortion happens in a way in which the lines of the grid are each divided into sub-lines of equal length (meaning for example that AB is divided into 5 parts of the equal length |AB|/5 and A(new)B(new) is divided into 5 parts of the equal length |A(new)B(new)|/5). The distortion is done with the DistortImage class of the Sandy 3D Flash engine. (My practical task is to distort an image using this class where the handles are not positioned at the corners of the image like in this demo but somewhere within it).

  • flex3 Format date without timezone

    - by Maurits de Boer
    I'm receiving a date from a server in milliseconds since 1-1-1970. I then use the DateFormatter to print the date to the screen. However, Flex adds timedifference and thus it displays a different time than what I got from the server. I've fixed this by changing the date before printing to screen. But I think that's a bad solution because the date object doesn't hold the correct date. Does anyone know how to use the dateFormatter to print the date, ignoring the timezone? this is how I did it: function getDateString(value:Date):String { var millisecondsPerMinute:int = 1000*60; var newDate:Date = new Date(value.time - (millisecondsPerMinute*value.timezoneOffset)); var dateFormatter:DateFormatter = new DateFormatter(); dateFormatter.formatString = "EEEE DD-MM-YYYY LL:MM AA"; return dateFormatter.format(newDate); }

  • Bitmapdata heavy usage - memory disaster (spark/FB4)

    - by keyle
    I've got a flex component which works pretty well but unfortunately turns into a disaster once used in a datagroup item renderer of about 40-50 items. Essentially it uses bitmapdata to take screenshot of a fully-rendered webpage in mx:HTML (this version of webkit rocks btw, miles better than flex 3). The code is pretty self-explanatory I think. http://noben.org/show/PageGrabber.mxml I've optimized it all I could, browsed, search for answers and already trimmed it down a lot, I'm desparate to reduce the memory usage (about 600mb after 100 draw) The Garbage collector has little effect. Thanks! Nic

  • Why would bitmap outperform vector, as3?

    - by VideoDnd
    Why would bitmap outperform vector? My Flash is for a large Kiosk, with rich media requirements and must function accurately as a counter. I want to keep everything vector for scalability. When I did a simple FPS test, I noticed my Bitmap version performed perfectly, and the all vector file was noticeably slower. PLEASE EXPLAIN • vector performance• what graphic standards I can apply• solutions for using vector KIOSK TEST ANIMATION RESULTS • only text and bitmap perform well, not vector • background and clouds OK, but more layers slow it down

  • AS3 Transition Manager problem

    I am using the TransitionManager class to pixel dissolve an image in an image gallery XML driven. It always stops half way through the animation...I hate Adobe Tween engines, I always used TweenMax without (almost) any problem but I would like to have the pixel dissolve effect. var myTM:TransitionManager = new TransitionManager(container_mc); myTM.addEventListener("allTransitionsOutDone",swapContent); myTM.startTransition({ type:PixelDissolve, direction:Transition.OUT, duration:1,easing:None.easeOut,xSections:200, ySections:200 }); Any suggestion?

  • FlexNativeMenu Problem in Air Application

    - by glatour
    I am trying to add a flexnativemenu to my air application and I have some problems... When I set it in the windowApplication, I get null errors in child controls so I tried to set this.menu = myMainMenu (which is my flexnativemenu) in the creation complete event but the menu doesn't show up... I tried to show an alert message before setting the menu and the menu appeared in the application. Is there a method I can call to force the application to "redraw" itself in the creationComplete event??? Thanks!

  • "multiply frog enemy" timer and array AS3

    - by VideoDnd
    How can I use the counter value to multiply the frogs in the array? My counter goes from 0-100. I want to prove that I can increment the enemies using a counter. EXPLAINED BETTER I have 10 frogs in an array. I want to use a timer to add 10 more frogs on each iteration of the TimerEvent.TIMER firing. //currentCount var timer:Timer = new Timer(1000, 50); timer.addEventListener(TimerEvent.TIMER, countdown); timer.start(); function countdown(event:TimerEvent) { // myText.text = String(0 + timer.currentCount); } //Creates 10 enemies "I want enemies to multiply 0-100" var enemyArray:Array = new Array(); for (var i:int = 0; i < 10; i++) { var noname:FrogClass = new FrogClass(); noname.x = i*10; //this will just assign some different x and y value depending on i. noname.y = i*11; enemyArray.push(noname); //put the enemy into the array addChild(noname); //puts it on the stage } SYMBOL PROPERTIES NAME "noname" CLASS "FrogClass" WHY I need specific examples using strings and arrays, because I'm stuck in a learning curve. Stupid examples are more fun!

  • Flex wordwrap issue with multiple text instances

    - by Craig Myles
    Hi, I have a scenario where I want to dynamically add words of text to a container so that it forms a paragraph of text which is wrapped neatly according to the size of the parent container. Each text element will have differing formatting, and will have differing user interaction options. For example, imagine the text " has just spoken out about ". Each word will be added to the container one at a time, at run time. The username in this case would be bold, and if clicked on will trigger an event. Same with the news article. The rest of the text is just plain text which, when clicked on, would do nothing. Now, I'm using Flex 3 so I don't have access to the fancy new text formatting tools. I've implemented a solution where the words are plotted onto a canvas, but this means that the words are wrapped at a particular y position (an arbitrary value I've chosen). When the container is resized, the words still wrap at that position which leaves lots of space. I thought about adding each text element to an Array Collection and using this as a datasource for a Tile List, but Tile Lists don't support variable column widths (in my limited knowledge) so each word would use the same amount of space which isn't ideal. Does anyone know how I can plot words onto a container so that I can retain formatting, events and word wrapping at paragraph level, even if the container is resized?

  • Cutom event dispatchment location

    - by Martino Wullems
    Hello, I've been looking into custom event (listeners) for quite some time, but never succeeded in making one. There are so many different mehods, extending the Event class, but also Extending the EventDispatcher class, very confusing! I want to settle with this once and for all and learn the appriopate technique. package{ import flash.events.Event; public class CustomEvent extends Event{ public static const TEST:String = 'test'; //what exac is the purpose of the value in the string? public var data:Object; public function CustomEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false, data:Object = null):void { this.data = data; super(); } } } As far as I know a custom class where you set the requirements for the event to be dispatched has to be made: package { import flash.display.MovieClip; public class TestClass extends MovieClip { public function TestClass():void { if (ConditionForHoldToComplete == true) { dispatchEvent(new Event(CustomEvent.TEST)); } } } } I'm not sure if this is correct, but it should be something along the lines of this. Now What I want is something like a mouseevent, which can be applied to a target and does not require a specific class. It would have to work something like this: package com.op_pad._events{ import flash.events.MouseEvent; import flash.utils.Timer; import flash.events.TimerEvent; import flash.events.EventDispatcher; import flash.events.Event; public class HoldEvent extends Event { public static const HOLD_COMPLETE:String = "hold completed"; var timer:Timer; public function SpriteEvent(type:String, bubbles:Boolean=true, cancelable:Boolean=false) { super( type, bubbles, cancelable ); timer = new Timer(1000, 1); //somehow find the target where is event is placed upon -> target.addEventlistener target.addEventListener(MouseEvent.MOUSE_DOWN, startTimer); target.addEventListener(MouseEvent.MOUSE_UP, stopTimer); } public override function clone():Event { return new SpriteEvent(type, bubbles, cancelable); } public override function toString():String { return formatToString("MovieEvent", "type", "bubbles", "cancelable", "eventPhase"); } ////////////////////////////////// ///// c o n d i t i o n s ///// ////////////////////////////////// private function startTimer(e:MouseEvent):void { timer.start(); timer.addEventListener(TimerEvent.TIMER_COMPLETE, complete); } private function stopTimer(e:MouseEvent):void { timer.stop() } public function complete(e:TimerEvent):void { dispatchEvent(new HoldEvent(HoldEvent.HOLD_COMPLETE)); } } } This obviously won't work, but should give you an idea of what I want to achieve. This should be possible because mouseevent can be applied to about everything.The main problem is that I don't know where I should set the requirements for the event to be executed to be able to apply it to movieclips and sprites. Thanks in advance
