I'm loading in an external swf with the code below (which works great), but occasionally I need to clear out "gameHolder" with a call of "removeChild(gameHolder);" but it doesn't work. I believe it is because the contents of "gameHolder" is a displayObject instead of a movieClip.
Code:

{
var mLoader:Loader = new Loader(); [code]....
What would be the most efficent way to remove the children from a sprite/movieclip in respect to memory and garbage collection?I have seen atleast three ways.Simple re-assigment
sprite = new Sprite();
null and then new

I would like to be able to quickly check if a given DisplayObject is a descendant (not in the inheritance sense - ie. child, grandchild, great-grandchild, great-great-grandchild, etc.) of another DisplayObject. There doesn't seem to be a native way to do this and I can only think of two ways to achieve it: Create the mother of all nested loops. Seems a bit, I dunno, wrong? Dispatch a bubbling event at the 'child' and check if the potential 'parent' receives it.

I've come across a pretty bizarre bug in my code when working with level generation in a side-scrolling platformer I'm trying to make... I've been desperately trying to debug it for the past 2 days! I have a movieclip (exported for AS) called Section1, that contains the first section for a level. It's basically a huge movieclip containing other movieclips; this Section1 movieclip contains the graphics for the level, as well as collision detection (the graphics are .pngs converted into movieclips, the collision detection is transparent rectangles converted to movieclips). FYI, it's a BIG movieclip... roughly 3400 pixels wide.
So, since it is the 1st section of a level, I have it spawn at the beginning of the game. However, I need to access all the platforms, walls, and graphics inside section1 from inside AS. So, here's the code I am using to do this:
public var s1:Section1;
public var platforms:Array, walls:Array, levelGraphics:Array;
...
// in Main's constructor now:
s1 = new Section1(2236, 8);

Initially, it works... I've traced the data in the arrays in my update method (run every frame), and I can see that the arrays contain displayobjects... for a split second, that is. Seemingly out of nowhere, the values for all the elements in the arrays become NaN! I think to myself... of course these DisplayObjects are "not a number"... they're displayobjects! Of course, this renders my arrays useless, since I can no longer access the data I need to do collision detections!
I can rotate it, or modify>transform>rotate +/- value
but what is the manual equivilant to simply object.rotation=0;
I have 2 sprite which I create near the beginning of my video application. A bg and screenOverlay. On the first load of the file all is good but when I navigate away and then return to the swf my bg and screenOverlay do not get added to the displayList. I have a example up here at [url]...

View 1 RepliesI know how to draw a rectangle and add it to a DisplayObjectContainer,but do you see a simpler method to directly add a border to a DisplayObject? DisplayObject don't seem to have addChild(), so I would have to add it on the parent, which is not perfect in my opinion...
View 3 RepliesI have a grid of DisplayObjects that when I put a glow on any of them, the glow overlap the other objects.

I am trying to understand the interaction between Flex UIComponents and (Flash?) DisplayObjects... But it's not clear to me what the UIComponent class "adds" to DisplayObject. So, what can a UIComponent do that a DisplayObject cannot?
View 2 RepliesActionScript Code:
mc.addEventListener(MouseEvent.CLICK,clic);
function clic(evt:MouseEvent){
var clip:MovieClip=evt.target as MovieClip;
removeChild(clip);
}
1) Why it's also possible write removeChild(DisplayObject(clip)) and for what? In which case it's necessary?
2) if I write var clip=evt.target it's works too but if I write var clip:MovieClip=evt.target it doesn't work. Why? It's a movieClip that should go in the variable var.
I am trying to store data in an object about different objects, but right now i am using their names. This was working at first but if I have 2 movieclips of the same class (from the library), then their children will both have the same names and this messes with my data storage.

Its dimensions (4278, 3977) are too large to be drawn."To make this kind of effect I use the rotationX function and when I zoom in I tween the "z" property. I dynamically generate all thumbnails and show them as a grid using some XML data.
View 2 Repliesi'm looping though a display object and trying to reset some button. the issue i'm having is i'm getting and error:1119: Access of possibly undefined property menuText through a reference with static type flash.displayisplayObject.on the line where i try and target obj.menuText below. the weird thing is that this same code works when the actionscript isn't in a document class. i think i'm importing all the classes i need. also in the document class i had to add the MovieClip(obj) as pointed out below or i'd get an error similar to the one about.why moving this into a package is causing this?

Firstly, I've created a global variable called mc to store a movieclip instance:[code]Later on inside a function, I've created a new instance of my movieclip and added it to the stage.[code]Now, this is working fine most of the time. But at one particular point in my program, after many other things have happened, when trying to remove this movieclip it throws the 'display object must be a child of the caller' error.So, I'm thinking if mc isn't a child of the stage, what is it a child of? Tracing mc.parent returns null - so it seems to be telling me that the parent (which was definitely the stage when it was created) has wandered of somewhere and abandoned my movieclip!I have no idea how this has happened, and as the whole program is several thousand lines long I can't post it here. So, does anyone have any idea what might cause a display object which is added to the stage to become orphaned like this?
View 1 RepliesMy friend and I are working on a flash project in actionscript 3, and we are trying to interact with the timeline of a DisplayObject (such as stopping, playing, gotoAndStop/gotoAndPlay), the same way you would if it was a MovieClip. None of the regular commands to navigate the timeline are working on it. Is there any way that we could treat it as a MovieClip or inteact with it as if it was one?
View 7 RepliesAt startup I want to know in AS3 if a DisplayObject has been mirrored in the X or Y-axis during artwork. Basically I want to know if a MovieClip got a negative scaleX or scaleY after using free-transforms.
myDisplayObject.scaleX and myDisplayObject.scaleY always starts out positive regardless any mirror actions during artwork.
The two functions I desire are:
function mirroredInXAxis(dpo:DisplayObject):Boolean;
function mirroredInYAxis(dpo:DisplayObject):Boolean;
I want to know which DisplayObject that is visible atposition x,y. Unfortunately, hitTestPoint returns true even ifanother DisplayObject lies above and blocks all visibility. Forexample:

View 1 RepliesI have a button (VehiclesButton) which on rollover I want it to trigger a mouse event so an image(VehiclesCentral) to the side of it (I've just set the alpha to 0 so its invisble, but its on the stage) will have its alpha increased to 100 and become visible
VehiclesButton.addEventListener(MouseEvent.MOUSE_OVER,test);

i'm creating a visual editor in flex and need to let users export thier projects into Image format. But i have one problem: size of the canvas is fixed and when user add element which is out of these sizes some scroll bars added. And user continue working on the project. but when he want to take snapshot of the canvas he just get the visible part ot the canvas with scrollbars. how to get image of the fullsize canvas?
The only solution i found is to check the positions and sizes of canvas child objects and rezise it to fit them. then take snap and resize back. But it hmmmm... too complicated i think. Is there some "easy methods"?

In regards to as3 project: Is there a way to inherit the properties of a given DisplayObject? I am looking for a single method that will grab something like the x, y, width, height, color, etc. Whatever is involved in the common classes between the two display objects.
Edit:
I don't think I was clear enough... Let me give an example of the type of functionality I am looking for.
var sp1:Sprite = new Sprite();
sp1.x = 30;
sp1.y = 30;
sp1.width = 500;
sp1.height = 30;
var tf1:TextField = new TextField();
tf1.inheritTransform(sp1);
So, in this case I know that the method 'inheritTransform()' doesn't exist, but I am wondering if there is something similar. Or maybe I am missing the point of extending a class in some way? I don't see how the two would relate in such a case.

View 1 RepliesI have a DisplayObject (let it be a Sprite). What I need is to make content under it black-and-white (only within its borders).
View 2 RepliesI have a getter within a class which is used to make my property skin:DisplayObject read-only. This class also has a property body:AvBody which is used to define the x y width height etc of the object, which in turn positions the skin.
What I want to do is disable access to the properties x and y on skin unless accessed from within the internal namespace (where AvBody is also located) Is this possible?
Note: I can't make skin any type other than DisplayObject (I can't even make skin a class that extends DisplayObject because it creates issues with library symbols).
