Flex :: AS3 - Removing Objects By Array Item Reference
Jan 2, 2010
I am trying to add some Sprite objects as the contents of an array, and I would like to be able to "clear" them from the stage. I would assume that if there are loaders involved, I need to do
_imgArray[i].close();
_imgArray[i].unload();
And if I am using a sprite, I can do:
removeChild(_imgArray[i]);
None of the above work.
Currently I try:
for(i = 0; i < _localXML.length(); i++) {
var tmp:BMLink = new BMLink(_localXML[i], _bw, _bh, i);
_imgArray[i] = tmp;
_imgArray[i].x = (_bw + _mainpad) * i;
_base.addChild(_imgArray[i]);
But this doesn't work.
The class instances that are populating the array are all extending sprite, but they have their own individual loaders inside w/ progress events etc.
I have 2 arrays & 2 checkbox repeaters: the second gets populated w/ items selected from the first. I can add the items no problem. How do I then delete the item if it gets deselected from the first checkbox repeater?
I've created a navigation system using Flash 3D functionality. It consists of a MovieClip with a rounded rectangle + a text with no-antialias bitmap font. I'm using Tweener to modify the z co-ordinates of the mc to make it "slide onto" the stage. However when the mc is completed animating it is notably blurry (the text at least). I was wondering if it might just be because it's in 3D-space the perspective (which hasn't been modified) is throwing the rendering off. So onComplete of the animation I try assigning null to the z-value in hopes of removing the item from the 3D space. I've attached the package code I'm using to create and animate the navigation feature.
I am having an array of movieclips and when my circle(controlled with the keyboard) hitTests true with one of the movieclips inside that array i want to remove that movieclip from the array so when i hitTest it again it returns false (I hitTest using a "for in" with that array).How do i remove a specific item from within an array?
I have an unordered ever-changing array that looks something like this:
12,23,1,4,11
I just want to basically tell the code to remove a specific item, let's say "23". But since the array is constantly changing length, I can't use splice.I also can't have any gaps, such as "12,,1,4,11". It must return "12,1,4,11".And on a related note, can I then check if this array has the same content of numbers as another array (and do I have to put them both in numeric order before it can perform the check, or doesn't it matter that they're not in the same order, as long as they have the same contents)?
I have what I think should be a very simple problem. I have an array and can access an element of it like this:
var test = finalArray[0]; Will be a number between 1 and 7
say this will trace a number.No there is a movieclip on the root of stage whose name is a letter (always the same, say "R") and whatever the number is. I'm trying to get this movieclip to gotoAndStop at the frame corresponding to the number that is test. However this isn't working:
function removeFromArray(item:Object, arr:Array):Object { for(var i:uint = 0; i < arr.length; i++) { if(item == arr
[Code]....
This function searches through an array and sees if an item exists in it, if it does, it removes it and returns a reference to that item.
This works fine for most things. But I just ran into a problem where I need to remove an array from an array.
so my array looks like this [ [item1a, item1b], [item2a, item2b] ]; and i need to remove [item1a, item1b] from it. But passing in the the array to remove and the full array to remove it from does not work because i guess of the casting to an object in the parameters list. Can the functionality i want be used? if so how?
I have made a class that creates a dotted line following a moving object. The dotted line is small circle added to the stage (and to an array) every half a second at the object's position.
First I add the circles to the stage, when the object stops moving I remove them from the stage.
This, however, only works twice, after that it throws a "display object must be a child of the caller" warning.
ActionScript Code: public class Path extends MovieClip { var tInterval:Timer=new Timer(50,500); var pathArray:Array=new Array ;
When would you want to use removeAll() vs just new ArrayCollection when you want to clear an array collection. Remove all iterates though each item in the list. I can't see a case when I would want to use it.
So a small example of my situation...On my stage I have 5 items labeled item1_mc, item2_mc, item3_mc and so forth...they all have two keyframes on their respective timelines, one labeled "active" and the other "inactive". My code contains 2 arrays, inactiveArray and activeArray and a variable known as energy that regularly goes to and from 0 - 100.
What I am looking to achieve is basically the function of...
if energy >= "insert given items 'active threshold' 20, 40, 60, etc..." then add it to the activeArray, if it is not, remove it and add it to the inactive array.
all objects in activeArray gotoAndStop("active");
all objects in inactiveArray gotoAndStop("inactive");
I have tried many different ways of achieving this effect but I always end up with duplicates and extras or something doesn't move when it's supposed to, where it's supposed to, it just ends up into a giant cluttered mess and I start from scratch.
I want to loop through an array of map tile coordinates, place a tile on the stage for each coordinate, and put a reference to each tile instance in a separate multidimensional array called mapRef, where the tile instances can later be referenced by their coordinates in mapRef. Is this line (excerpt from the code below)... Main.mapRef[i][j] = mapTile;.[code]
I'm having trouble with my code. I keep getting this error TypeError: Error #1009: Cannot access a property or method of a null object reference. at Test_fla::MainTimeline/frame1() I believe it has something to do with the array, considering it works when I remove the array stuff. What I'm trying to do is to be able to move objects through an array with my gravitate() function in the Grav Class.
stage.addEventListener(Event.ENTER_FRAME,onLoop, false, 0, true); for(var i:uint=0; i < numParticles; i++){ var p:Grav = new Grav(5, 0xff0000, Math.random()*250, Math.random()*250); addChild(p); particles.push(p); } function onLoop(evt:Event):void { //for(var i:uint=0; i < numParticles; i++){ //particles[i].gravitate(1,1); //}}
I have a service which returns an Array of ObjectProxy objects. I would like to cast this to a custom object (a value object) and create an ArrayCollection. How can I do this?ited:I am using Django and PyAMF for the backend. I had to write a custom SQL query and I am wrapping the resulting records in ObjectProxy and sending the whole result as an ArrayCollection.Here is my client side code:
[ArrayElementType("SessionVO")] [Bindable] private var _list:ArrayCollection;
I have a custom component as an item renderer.In this renderer there is an item called dlFirstChoice.Now when I add more items to this list and force the list to rebuild itself something odd happens.Part of the creation of the renderer I set a default selection for the DropDownlist as follows: dlFirstChoice.selectedIndex=0The problem is once I have more than one item to render from my dataset this property stops working. So if my dataset has only 1 item to render the drop downlist sets itseld up properly, the momment I need to render more than 1 copy of my item renderer, all of a sudden nothing gets set fo
I have a Flex tree with an ArrayCollection as data provider. The collection holds an array of CategoryVO objects. Each object can have another array of CategoryVO objects inside it's "child" attribute. This way the tree displays the data correctly. Now I want to get the parent of a specific item, e.g. tree.selectedItem. Using XML as data provider the item parent is avaiable thorugh the parent() method. But I can't convert my data to XML. How can I get an item's parent? Perphaps using the tree's dataDescriptor?
I'm doing an geometry object tranformations for a project. I need to have same rectangle across 4 parts in a screen. So when i change one rectangle others will be transformed like scaling or something.So i was able to do this with image, just giving "source" attribute. How to do with geometry objects?[code]
var str:String=cntslst.text; var results:Array = str.split(","); for(i=0;i<result.length;i++) {<mx:NumberValidator source="{result[i]}" property="text" id="cell" />} Is it possible ?
I have a label inside a repeater (rptInfos), and I have an arraycollection (Texts) that has the translations. The "Texts" content is changing when I change the language, and normally I use {Texts.getItemAt(219}} for example when I need a translated text. But in the repeater I have a translateable column, so I want to use it like this:
<s:Label text="{Texts.getItemAt(rptInfos.currentItem.DictID as int)}" />
but it says "Syntax error: expected a definition keyword (such as function) after attribute , not target".I wanted to translate it in the labels creationComplete event, but than I can forget about binding, so only when reloaded can I have the content to update.
I've been trying to remove duplicates from an array for a while, or even preventing them, and I'm having nothing but trouble.There's a lot of code to go through.I'm creating an array with objects inside it like so...
Code: private function getJsonResult(event:Event):void { //ta.text+=http.lastResult;
I was thinking about Flash GC the other day and came up with a question about how reference counting would work in the following 4 class scenario (assume GuiMain is the movie's document class):
I have an arrayCollection with the following structure:
[Code]...
the AC is defined as follows:[Bindable] private var projectErrorsAC:ArrayCollection = new ArrayCollection;
I'm using this AC in a repeater to display each error. After each error is shown, I've placed an "Accept" and "Deny" button. Once the user clicks either one of these buttons, I'd like to call a function that removes the particular error from the AC. Here's what I have so far:
I am working with XML in ActionScript and trying to find a way to remove a node by providing the node reference.
[Code]...
Somehow I just do not feel like it is a very clean way of doing it, but it works. I am wondering if there is another way to delete the node by reference?
When the dataProvider for an DataGrid is an array of objects, how do I set each column's dataField to a property of the object.I have an ArrayCollection (say a) where each item is an objectFor example a[i] = data:ObjectWhere the object data has some subproperties - data.name, data.title, data.content etc.I have a DataGrid in which I want to display this data.So I put:
Example: var arr_1:Array = new Array(); arr_1.push({sdate:"2010-02-02",status:"New"}); arr_1.push({sdate:"2010-02-03",status:"New"}); arr_1.push({sdate:"2010-02-04",status:"New"}); arr_1.push({sdate:"2010-02-05",status:"New"}); How can I change element number 3 status to: "Old", without removing it. Just update the status value??
I have a chart and am trying to display the "volume" in a line chart as the primary series & the "temp" as a column chart as the secondary series...(the "compound" will be shown in the datatip):
[{date=Tue Feb 08 19:00:00 EST 2011, volume=1200, 1={temp=-50, compound=helium}, 0={temp=-45, compound=oxygen}}]
I can get the "volume" series to display fine, but cannot get the "temp" series to display...how do I access them? Right now I have:
I am using Flex to create a small form. All I have at the moment is a List component, that I want to populate with a list of font names.I am getting the fonts using Font.enumerateFonts(true);. This returns an array of flash.text.Font objects.
The Font objects have a fontName property that is a String of that fonts name.My problem is that I can't figure out how to bind the List's dataProvider to the fontName property of each of the Font objects in the Array.Is there a way to do this just with binding? and not creating a new array of Strings by looping through the Font objects?
