ActionScript 3.0 :: Objects - Removing The Item From The 3D Space
Dec 10, 2008
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 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.

my goal, which eludes me at the moment, is to display some variables (using a dynamic text box) along with some static text, to output in the following manner:[code]and so on.. but i want to be able have text areas somehow link to eachother, so if theres a large amount of variable, theres no overlap, or if theres only a small variable content, theres no 'blank' area.

I don't know why, but for some reason I'm not getting the contents of an array with the whitespace included on them.
Eg. "NewYork" instead of "New York"...
ActionScript Code:
var Cities:Array=[
"New York",
"New Delhi",

Is there a way to change the space between a spark form item and its content (textinput, combobox)? I already set to 0 the "gap" property of the form, but still there is a lot of vertical space left between the form inputs.

I am working on a Flash project where file size optimization is critical. I am curious if removing white space from the code (which lowers the size of the AS file) will reduce the size of the finished SWF or if the Flash compiler already does this?

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?

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.

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 like to call it a 3D engine, it can display triangles in 3D space and make shapes out of it. It works fine except that I have to manually change/remove/insert the coordinates of the points of triangles that make shapes. I would like to have a more practical way of putting dots in 3D space.

trying to color objects that are flying around in my space game.When I shoot and hit them - the affected enemies shall blink. The graphics are pre-rendered (i.e. there's an rotation array and function where the degrees and their appropriate rotation for the objects are stored / calculated for better performance).
So - my idea was to enhance that rotation function with a functionality for additional coloring; but the colored AND rotated objects shall be stored apart of the normal rotated objects. To accomplish this I made a nested array:in row one there are 360 rotated graphics of one object and in row two there are 360 graphics of a rotated and colored object.
Problem: Coloring works but they are not rotated (always at 0 degrees).
Code:
public function createRotationWithColorBlitArrayFromBD(sourceBitmapData:BitmapData, inc:int, offset:int = 0):Array
{
trace("sourceBitmapData.width=" + sourceBitmapData.width);

i"m hoping someone can help me with this I'm working with a slide show that has products of different widths. The idea is to make sure that when user clickes on the next/back buttons and the next (or prev) product shows up - to make sure that the product is not clipped either on left of stage (or live area) or right..

My new website is carolineofbrunswick (dot) co (dot) uk. As you can see, there's a ton of blank space off to the right of the pages, and I can't figure out how to get rid of it.
It's caused by the Flash objects in the right-hand column. Changing the width attributes on those Flash objects just causes them to not appear at all, though the blank space still exists.

I am using away3D and I have come across a stumbling block I cant get anyone to answer. I have tried EVERYTHING and I am not getting an answer on away3D forums.I place objects in 3D space. where the houses start at different y -value and z -value for reasons I dont know so they can look level.IT takes about 30 sec to load but here is my example of the problem . The objects move on the ground when they should not. I am just moving the camera. I dont underatnd how you place objects in 3D space in away3D.Here is the issue with my program after MANY hours of endless fiddling. The y value of the plane. It looks the same with value at -100 or -140 but it works at -140 where it is under all ojects. AT -100 it looks under all objects but doesnt move properly. Objects and the plane (ground) dont seem fixed.
// plane = new Plane({material:mygrass, name:"plane", z: 200,y:-100,x:-100, width:1000, height:1000, pushback:true});
plane = new Plane({material:mygrass, name:"plane", z: 200,y:-140,x:-100, width:1000,

i am having a problem removing objects from the stage and their associated arrays. basically when a "shark" is added to stage i want all "cans" to be removed and i dont want any "cans" to be added until the shark has left.my problem comes as i dont want to keep using for loops as i already have two or three for "cans" alone and i heard thats not good for the code!
Code:
var canTimer:Timer=new Timer(2000);
canTimer.addEventListener(TimerEvent.TIMER, addCan);
canTimer.start();
[code]....
im not 100% sure were to put this in my code-i didnt really want to put it in a function of it's own as it would mean using another for loop?i get a output error when a shark is added like this:
Quote:
TypeError: Error #2007: Parameter child must be non-null.
at flash.display:isplayObjectContainer/contains()
at dolphinmoviegame_fla::MainTimeline/canHitTest()
even though all "cans" are removed.

I have a utility function:
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 realize there are better ways of accomplishing this, but i'm learning and therefore only interested in why the above code doesn't work.

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 ;

I have a question about how best to remove display objects.removeChild(object);Given that there are no other reference to this object, does using removeChild alone make the object eligible for garbage collection, or does it also need to be given a null value as well?[code]In both these cases, I get the classic 1009 error. That leads me to believe that if you use removeChild, you don't also need to give the object a null value.?url...

I seem to be running into some garbage collection issues. I'm making an RTS game with a side scrolling map. I have a "game" layer on the stage which scrolls left and right, all the troops, vehicles, bullets, etc are within this layer. If I scroll the game layer to the far side of the map from some tanks placed at the other end, the tanks disappear. I can only assume flash is "helpfully" removing objects it thinks are too far away form the action to be of use any more. I'd rather it didn't.

I was just wondering--and it's probably an obvious question really--if I make an object null and that object had one or more event listeners registered, are the listeners removed?
for example:
Actionscript Code:
object.addEventListener(Event.SOME_EVENT,callBack);
function callBack(evt:Event):void
{
object = null;
[Code].....
In this case have I removed 'object''s listener when I made the object null?

I use this piece of code to create some eyecandy of debree falling. When an object is destroyed i spawn some rubble and let is fly over the screen. But... when i use this a lot, slowdown is there and even when all the objects are gone the slowdown stays. The good old 50fps won't come back anymore
public function destroyBlock(xPos,yPos,nrObjects) {
for (var debree = 0; debree < nrObjects; debree++) {
debreeObject = new mc_ground();

I have an animation of footprints being left on the ground as if by an invisible man or ghost. the animation consists of:
1 movieclip containing --> 5 footprints each one is an individual movieclip. Each print fades in and out using the Tween class with an alpha effect
The main timeline uses the following code to create random instances of the animation:
var myTimer:Timer = new Timer(12000);
myTimer.addEventListener("timer", timedFunction);
myTimer.start();
[Code].....
so it looks like the function is being called correctly and removing the first instance of FOOT from the stage. but the 2nd iteration generates the error. Is this is a problem with the timer? I would like to send this to someone for examination and assistance.

I'm trying to make a Starfield program as practice for ActionScript 3. I'm using a timer event in the document class to create Star objects which are defined by an object class connected to the movieclip Star in the Library. The object class has a timer as well, and at each tick it repositions itself a few points away and scales up, creating the image of a star shooting towards the sides of the stage. When the star has gone past the boundaries of the stage or when it has scaled to a certain size, it removes itself from the display list with the command: this.parent. removeChild(this);This removes the star from the display list just fine, however after that I can't get the star to set itself to null so that it will be removed from memory, and I'd like some suggestions on how to do this properly. An idea I had was to make a function in the document class that the child objects can call, something like this.parent.KillMe(this) which would give itself as a reference to the function, which could then use a local variable reference to set the child to null, removing it from memory. This all seems terribly complex, so I'm sure there's another way.
I haven't noticed a memory leak or slowdown, however, so I'm curious if objects without references that are removed from the display list are automatically removed? That could be both good and bad, as the object might want to add itself to the display list again at a later time; not in this Starfield program, but perhaps in another I write.
