ActionScript 3.0 :: Add A Clip To The Stage As A Child And Remove The Parent And Set The Parent Equal To Null?
Sep 11, 2010
if I add a clip to the stage as a child and remove the parent and set the parent equal to null, does the child get collected and removed from memory? What if the child has an image loaded into it as its child?
In my application I'm loading a series of png images as overlays that can be tinted for customizing in this app. When I trace my memory, the basic app idles at 64,000 k. The exact second I load those overlay images it goes up to 205,000k. If I remove those clips and "clear" the stage I should go back down to 64,000 k if everything is removed and collected correctly, right? It's not, it's hanging at 215,000 k. Are my images being cached and that is the reason for the memory staying up? If so, how do I prevent that. Or upon removing the parent of the image how can I un-cache the image.
If a user switches between models and loads several different items then the application actually crashes the Flash environment because of too much memory usage. It also does the same to browsers.
I got a "preloader" that creates an movieclip and loads an SWF. Now in the loaded SWF i want a close button to go back to the "preloader". The preloader isn't an actuall preloader but some sort of mainclip.Now i tried this:removeChild(MovieClip(e.currentTarget).parent.pare nt.parent)But i get error:ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller.at flash.display::DisplayObjectContainer/removeChild()at MethodInfo-6()
i am slightly confused about the parent and child relationship. lets assume we have several different instances, what would be difference of adding them all as children of the stage and creating a parent-child hierarchy between them(other than the access path).
[code]All clips are squared.Ok, on the PlayerPlane, there are little soldiers, which have hotkeys. The effect I'm trying to create is I want to position the GameStage so that the currently selected soldier appears in the center of the GameClicker clip.The GameStage is movable by the player (to scan other areas of the map)by holding the CTRL key, so it's easy to kinda lose track of where your players are.I have tried using localTo Global and globalToLocal techniques, but I think I'm lost on the actual math of getting the GameStage to move the correct distance so that the selected soldier is centered to the GameClicker.[code]
I'm currently making a platform game and when the player shoots i want to add the bullets to the stage. The players gun class is in charge of adding bullets. The "players gun" is a child of "players gun holder" which is a child of "player" which is a child of the stage. is there a better or more dynamic way for the "players gun" to add bullets to the stage rather than using parent.parent.parent.addChild (bullet);
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.[code]Sprite2 is a rectangle. When I rotate it, of course, the height of its parent, SpriteP, GROWS. But I would expect that height to go back to what it should be when I'm removing Sprite2!And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200.
I got a Parent Sprite, let's name it SpriteP, which holds inside it two other Sprites. Sprite1 and Sprite2.
When Sprite2 is NOT rotated:
Code: trace(SpriteP.width + ' ' + SpriteP.height); //100 250. SpriteP.removeChild(Sprite2) trace(SpriteP.width + ' ' + SpriteP.height); //100 200. -> works, 200 is good. When Sprite2 is rotated at 90:
[Code].....
And it does! If I remove Sprite2 while NOT being rotated, the height of the parent drops back to normal, 200. But if I rotate Sprite2, the Parent won't update its bounds.
I have an issue where removechild won't infact remove a child. I think its something to do with my dropTarget.parent issues. The concept of the code is that you drag a source onto a destination. When you drop the source onto the destination you will get a text field that says "Hello" or "Goodbye". The objective i want to achive is that once i drop a source onto the destination, removechild will remove any previouse textfields added. This is proving difficult.
I have a flex application with two objects: a parent widget (called an IBaseWidget) and a child widget (called a HelperWidget2).When the user clicks on a help link, a helper widget is loaded into the list of base widgets and then displayed for the user.However, when I try to access this child widget by casting the base widget in the collection to the child widget type,the child widget returns null and I am unable to work with the widget.The following snippet correctly returns the widget ID of the newly added widget and dispatches an event to load the widget:
var id:Number = WidgetManager.getInstance().getWidgetId("Helper"); ViewerContainer.dispatchEvent(new AppEvent(AppEvent.WIDGET_RUN, id, openQuickQueryCanvas));[code].........
The problem is that helperWidget above always returns null, meaning the cast isn't successful.
On the main timeline I have a movieclip called "sections". Within "sections" there are 2 movieclips (1 simple button called closeContent and a movieClip called content_aboutUs).I am trying to remove the button "closeContent" from the stage within the "content_aboutUs" movieclip.A following function is called within the "content_aboutUs" movieclip.
PHP Code: function closeTabContent(e:Event):void { parent.removeChild(closeContent);
I have a parent swf which loads many child swfs (though only one is displayed at a time). My intention was to use the loaded SWFs document class to retrieve an array of objects to be assigned a tab index, combine this with the parent's own array of objects and apply sequential tab indices to them all. But what happens is actually that the parent's objects are assigned an index, but the external swf is unaffected. In fact, the external swf retains its automatic tab indexing, when I would expect that having set a value for InteractiveObject.tabIndex, automatic tab indexing would be disabled.
I've seen similar tales elsewhere. Most posts I've read are wanting to load an external swf, give it focus and loop through those objects, then close the swf and return to looping through the parent. However I would like loop through all objects as one. including manipulating the focus manager(s), and basically fiddling with every tab-related property I know.
trying to on mouse over set the parent of the moused over text field to the highest depth child of its parent i tried both of these: [code] private function
I have a carousel of images that load an external swf movie with a FLVPlayback component on it. The problem is that when the external swf unloads the sound of the FLVPlayback component continues to play. I am using a carousel component I found online to load the images and each image loads an external swf file. here is the code for it.[code]...
I have created event listeners for a particular movieclip.Insidet this movieclip there is so many objects.When ever I click on the parent movieclip the event listener calls the function for the child object. I had tried removeEventLIstener()
import flash.display.MovieClip; import flash.events.Event; import flash.events.MouseEvent; var info:MovieClip=new MovieClip(); info.graphics.beginFill(0x000000,0.35); [Code] ..... I want to delete mc's parent
I am trying to make a calculator where a user can select from a list of items. If a user clicks say "ITEM1", it should add the item to a "CONTAINER_MC". The problem i have is all my data is set inside an array containing names and prices like the code below.
Here is a working script to drag drop a ball from the stage into another target mc:
ball.addEventListener(MouseEvent.MOUSE_DOWN, pickUp); stage.addEventListener(MouseEvent.MOUSE_UP, dropIt); function pickUp(event:MouseEvent):void{ [code]...
It works well but I'm new to AS3 and I am having difficulty amending this script to drag the ball out of a parent mc (instead of the stage) and onto another mc (the target mc). To explain: imagine a ball, a box, a tri, + more shapes all within a scrolling mc (initial parent), the user scrolls to select a shape, then drag-drops onto a target mc on the stage.The scrolling is no problem, but how would you amend the script above so that the ball can start inside a parent mc rather than on the stage itself?
I've struggled with this for a long time and have thrown in the towel. How the heck do you climb the ladder, then go back down again into another clip?
I'm working on a project for my elementary school students using a book, some mp3s, and some images of text. The main movie clip is called "halloweenWitch" and it's about 10,000 frames long. Every 500 frames or so there's a keyframe for new images of the text. I'm trying to access child movie clips (mc0-mc18) to tween (resize) using code that I found here. [URL] However when I try to access the children with:
Code: Effects.resizeIt(halloweenWitch.mc0,1,2,2); From the main timeline I get an error. TypeError: Error #1009: Cannot access a property or method of a null object reference.
When I debugged the program it said that the problem was this line in my Effects.as file. Code: targetMC.addEventListener(MouseEvent.ROLL_OVER, resizing,false,0,true); targetMC.addEventListener(MouseEvent.ROLL_OUT, resizing2,false,0,true);
I think it has something to do with initialization but I'm not sure how to write a function that would tell the stage to wait until all objects inside halloweenWitch are present, nor even if that's what I'm supposed to do. Code: targetMC.addEventListener(Event.ADDED_TO_STAGE, init); ??
I've been working on an interactive map of the counties in Montana. When a user clicks on a county, I'd like the map to zoom to the county's extent and center it on the stage. Every county is a child of a larger container (the state, names allcnt_mc). I've set things up in my function so that when you click on a county POINT variables with all the numbers you need are created. I just cannot get the desired effect and I think I am missing something basic in regards to the geometry of my stage. Can anyone see something I am missing? I set this up so that the parent is tweened to a new location equal to stage center minus the called child's x,y distance from stage center. Essentially, this should center the child over the stage center, no?
function tweenparent(e:MouseEvent):void{ //create vars for x,y cordinates of clicked county (child) var calledx:Number=allcnt_mc[xmlData.row.NAME[e.currentTarget.ivar]].x;
I'm having a hard time working out the most appropriate way to move a child movieclip between parent objects.
I'm creating a board-game type game wherein I've dynamically created an array of 'Square' movieclips, with no visual elements, which are arranged in a 10x10 rectangle on the stage. I then dynamically add the appropriate types of piece movieclips to the various squares with the addChild() method. In general, a square should only have one child piece at a time.
All of this works well for setting up the play area, but now I'm having an issue with moving a piece from one square to another. I want to have the user click a square with a piece on it, then click the destination square to move the piece. I have the logic for determining where a user can move any given piece to, but I don't know how to actually move the piece.
The pieces are all different class objects that extend both a base class I call Piece as well as the MovieClip class. The main issue is that when dynamically adding the various pieces to the squares, I don't provide them a unique name to access them later. I don't bother with unique names because I have no way of knowing which piece instance will be in a given square, so using getChildByName(name:String) isn't very useful.
So I can think of two routes that I can take: Making a getter/setter for the Square class that manages a private Piece property (as well as the adding and removing of the child piece to/from the parent square), or using getChildAt(index:int) to try to access the child piece.
I want to go with the first route as it seems to be the most maintainable to me. My problem is that I can't work out how to manage empty squares in this scenario. My instinct is to null to private _piece property of one square once I've moved the child piece instance to another square... but I'm fairly certain that the private property is a reference type, and nulling it out will null the actual piece object even after it's changed parents.
My player movie clip has a smaller movieclip within it. Because the smaller movieclip is not within the parent clip it changes the x,y,width,and height value of the player movieclip and throwing everything off! To adjust I have to add (-2ndmovieclip.height) to everything i want to do. This is sloppy and I don't like it. Is there a better way to have a child within a movieclip without it affecting the parents properties? i want the parent to keep its original x,y,width,and height properties but the child keeps adding to them!
I would like to know the way to prevent a child swf from referencing its parent swf stage width/height?
for example, i created a child swf that loads image and center it on it's stage. As a stand alone its fine but i loaded it with parent swf, it centers on the parent swf instead.
I am trying to load a swf into a holder movie clip from the child movieclip.It's parent has a holder that i want to load a swf into.I am navigating from within a child clip.It would be nice to have the swfs load from an external xml file but it isn't mandatory.
That class has a loop that creates / instantiates a number of copies of another movieclip from the library. This second movieclip has a textfield child in it. When I convert this textfield to a movieclip I can access the properties of it fine, but just as a dynamic textbox I can't access it.
This is the custom class of the second movieclip that gets instatiated a few times by the first custom class...
This custom class relates to a movieclip that has a child MC called recent_text (which I can access ok) and in that child is another child (a dynamic text field called "aDynamicTextBox", which I can't access)[code]...
below shows how to add child in a movieclip. ebd.target.addChild(info_grd); there is button named my_btn inside the movieclip info_grd.I would like to remove movieclip info_grd.parent
i am trying to use the Tween class to change the size of movie clip to certain height.the code works for me but when resizing the parent, it effects the child.i tried the height and scaleY property for the thum, but does not work.
