ActionScript 3.0 :: Removing Objects In Tree Structure From Display List
Mar 21, 2011
I've asked this question before but had no answers... so here I go again I have a structure of objects: Top object A has as children (addChild children that is...) one or more objects B_1 to B_n. The B_n may in turn have one (1) associated object A' (Same type as top object, not displayed to begin with). When I click a B_n two things may happen:
1. If it has as associated object a A', put it on the stage (as child to B_n).
2. Otherwise it is a leaf and it does other things.
If '2' happens I want to collapse the tree, that is remove the top and all children of same type from being displayed. I thought a recursive approach should work:
Scenario 1: Within some 3D container object, I would like to add two Cubes: one without any transformation, and one with small position, rotation and scale adjustments. After adding those two cubes, I would like to also transform the container's position, rotation and scale.
Scenario 2: In a 3D character's body, it consists of many hierarchical children (and subchildren), each having various transformations over the course of an animation.
How do I calculate these individual 3D object transformations efficiently? Can it even be possible to do this with only one VertexBuffer3D? Or do I need several VertexBuffer3D to keep track of each objects? Using multiple VertexBuffer3D seems like it could hit a limit (but I haven't read enough of the Stage3D / Context3D documentation to know for sure).
Is there a way display the display list in the Tree component. I could parse the display list into xml but then I would not be able to create a reference to the display object.
I have a list containing display objects from throughout the application (insertion order). I want to process the list either top-down (parent, child) or bottom up (child, parent). The only requirement is that either a parent is processed before any child or vice versa a child before its parent. What is a good approach? This question is not about sorting a list. It's about retrieving the depth of a particular display object.
Example Display list: A (root) B1 C1 C2 D1 B2 ......
My list: list = [E1, F4, A, B2, B1, C3, ..., N9, N8]
Bottom-up: N9, N8, F4, E1, C3, B2, B1, A
Top-down: A, B2, B1, C3, E1, F4, N9, N8 Does not matter if N9 before N8 or N8 before N9. Important is that any N is before M (first run) or any M before its children N* (second run).
I have an application that uses a main class to control other MovieClips, adding and removing them as needed, most of them are separate screens or sub menus.
When I leave the main menu and come back to it later from another screen, certain animations and roll over buttons still play, which I don't want, I basically need the main menu screen to reset every time it is seen.
I read up on this and found out that removing the child doesn't necessarily remove it from the memory.
I tried setting the mainmenu to null before moving onto a different screen but this threw up an error, stating that the parameter child must be none null.
how to completely kill my mainmenu when it is not needed.
public function confSubMenuOneScreen():void { subMenuOneScreen = new SubMenuOne(); mainmenu = null;
[Code].....
This is the example of code that removes the menu and adds another screen, with the mainmenu = null code that throws up the error.
How do I identify all the display objects in the display list in ActionScript, bellow the one that I have clicked? All the other objects are shadowed by the first one. What if other objects have visible parameter as hidden?
why I cant kill a child in my display list. So I'm working on an ad that is going to load in different swfs depending on the link you click. What I wanted to happen is when the ad loads the first swf is auto loaded in to my container. Then when you click on the next link the new swf would cancel out the last one. What I am getting is an overlap of the swfs and I understand that. I can't figure out how to kill the other children. I tried unload and remove child but have been unsuccessful.
i don't understand why none of my display objects are not being removed. when i press the button, i'm expecting a trace and removal of both shapes and the button, but nothing happens:
[Code]...
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.
If you're removing a MovieClip from the display list, and that MovieClip in turn has child MovieClips which have their own event listeners, is it necessary to remove ALL listeners from the child MovieClips? or just the parent MovieClip that is being directly removed from the display list?
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.
When I'm removing an object from the display list (via removeChild), I'm performing a splice on all of the arrays that the object has:
[Code]....
My thinking was that this frees up some memory similar to disposing a bitmapdata. Does this even do anything? Or, will arrays be cleared and the memory usage restored when the object is removeChilded?
I have a stage with instances of bauble_mcs on it that are attached by the document class of the main timeline (can someone tell me what the right term is here? I don't know what I call the main time line in AS3).
I then have instances of snow_mc attached by the same class. Inside the snow_mc I want to test to see if it is hitting any bauble_mcs but I don't know how!
I have read one xml file and created a tree structure now if I click on any one of its node..it should load another xml file and create a subtree under the node..
So, events bubble up the display list. That's great if that's what you want. But what if you have objects on the stage that are not related that need to listen for events from each other? A simplified example:
var objA = new ObjA; addChild(objA); var objB = new ObjB;
[Code]....
Object B can listen for events dispatched by object C. But I also need object A to listen for events dispatched by object C. Also, these objects are created in different classes so I can't hard code references to each other.
I have some kind of UIComponent grouping which may look something like this with the classes "Group" and "Element". Groups can have children and children may be elements or groups again, basically similar to a file system or the str+g group function in several graphics programs. The simplest form of a group is a group with only children which are also the most low level groups in the tree.
The display hierarchy is already existant, i try to persist it to xml. Group - element - Group - element - Group -element -element - element - element
I want to rebuild this structure in an xml-document for persistence. I know how to build an xml document in Flex but not how to (recursively) traverse this n-tree correctly. For getting only the child nodes one could make use of the following algorithm (pseudo code). But somehow I don't understand how to create the xml from this.
Is there a way to group context menu items into a tree like structure?Like the Quality in built in menu.You can test it on any flash that has the built in items enabled.Right Click -> Quality -> Low.Can you do the same with custom items?For example:Right Click -> Custom Options -> Option 1
Does anybody tried Dynamic column grouping using Hirarchical/tree data structure in Flex advanced datagrid ? is it possible to create a column header dynamically and so the datagrid column with using certain datafield using dataprovider dat.
Here i'm setting the disclosureClosedIcon as null setStyle("disclosureClosedIcon", "nullicon"); Anybody have idea about how to replace this default icon with a movieClip?
I'm trying to make a Flex Tree Component display the children of a sprite in a hierarchical way. Moreover, dragging the items on the FlexTree would resort and reparent the items. I have special Elements set as Folders. This would allow other elements to be added there as a children by dragging an element on the tree and dropping it there. I have a failed attempt which works, but breaks when I try to add folders. Basically, it fails at reparenting the items by dragging and resorting folders and that Does anyone know of a component or something which can do this, has anyone have created any of this or could anyone give me a clue?
Is there a way for an XML file to be displayed in a textfield in Flash just like it's displayed in a text editor? I mean... displaying it and keeping the original XML text formatting (including white spaces, indents etc.)?
I have a basic Tree built in Flex. The Tree works fine. I'm attempting to get a list of all of the visible nodes. I know there is a Tree.openItems, but that does not suffice because (for example) if you open all the items in your tree and then close the root, the invisible opened items are still counted.
I have an accordion component that contains 3 list components and 2 tree components...there are all the components from the flash library of components...and I need to print the contents of these 5 "lists"For now I'm concentrating on the lists...then I will worry about how to print the trees with all the nodes expanded...but I can't seem to figure out how to determine how many items are in a list.
I'm building an application, where objects are attached on a canvas and the tree of that canvas is held on a tree component. Each time that i attach an object the tree adds a new child etc. I want to do this on the other way around.. I want to press a tree node and "communicate" with the specific object, so that i can change its color, delete it etc. I've tried some things but nothing happens!This is my code:
var working_space:XML = new XML(); working_space.addTreeNode("Canvas",0); myTree.dataProvider = working_space;
By default, the iconFunction of List and Tree return only Class as the icon, which is for embeded images or iconUtility kindly provided by this site http:[url]...... It works very well with pre-created images.But what I really want is to accept a completely runtime generate sprite object, similar to what is done by Legend, with the color changes according to what the current status. I assume I could do something to make the ListBase to accept icon argument other than Class.
Now I have added my tree just below the list and I have saved counting from 10 to 19 in one.xml, 20 to 29 in two.xml and so on in different XML file. I have no clue how to connect the XML containing counting from 10 to 19 as the single node in tree at the selection of label one in list
