ActionScript 3.0 :: Accessing Dynamically Created Movieclips
Nov 21, 2008
I have an application that I am adding movieclips to a container movieclip through a for loop and repeatedly calling myClip.addChild(theNewClip). Now I have a dozen clips in my container and it seems like the only way to access the clip is to use the getChildByName() method and cast it into a temporary clip so I can get at the its properties.
Is this the best and/or only way to do this? Does the old AS2 myContainer["theName"].property not work with dynamically created movieclips? It doesn't seem to work for me anymore.

I have a movie clip menu on a main timeline and inside that movie clip I have created four buttons dynamically. How to access those nested buttons/movieClips (add event listeners etc) from main timeline? Here I am adding menu to the display list on main timeline:
I am able to dynamically create an object on the stage with a function, but I am at a loss for how to access and manipulate the properties of that object from my Main Class.
in my Main Class I have:
ActionScript Code: NLP_addChild.addObject(stage) // NLP_addChild is the other class addObject() is the function
in NLP_addChild Class appears the following:
ActionScript Code: public static function addObject(stage:Stage) { var myCircle:MovieClip = new circle()
[code]....
myCircle displays correctly on the stage, myCircle is correctly assigned an x of 300. But myCircle x property cannot be assigned from my main class.
If objects are created dynamically in AS3, using code like this:
for (var num:Number = 0; num<10; num++){ var txtFld:TextField = new TextField(); txtFld.text = 'This is the original text'; this.addChild(txtFld); }
then later, i want to changet the text of one of the TextFields, how can I do that? The only instance listed in the variables is a single instance of "txtFld" and it is the last one that is created. How can I access the others?
but when I put MC on stage dynamically via addChild, the first trace gives compiler error while second trace works(error: Scene 1, Layer 'Layer 1', Frame 1, Line 81120: Access of undefined property myParent1)
I'm trying to build a relatively simple photo gallery where the images are loaded via XML into thumbnail movieclips that have been dynamically generated, positioned and added to the display stack. I used a simple for loop to generate the thumbs and traced the thumb.name to make sure they all had unique instance names. I then added a listener to the thumb mcs in the for loop and created a function that traces the instance name of each thumb mc, to see if all is working, however, every thumb mc traces the same instance name. My question is how can I create the thumbs dynamically in a loop and, essentially, make them buttons that would display the big the full size photo.
Here is my prototype code:
ActionScript Code: for (var i=0; i<12; i++) { var thumb_mc:MovieClip = new thumb(); // Positioning: The xy coordinates are in an array outside the for loop.
Im dynamically creating an instance of a movieclip, call it a game piece. This game piece has 4 frames, each with a movieclip called base(although one is red, one blue, one green, one yellow). When the game piece is created I set the frame to indicate player color. Im also changing the alpha of base to 1.0 when its being dragged, 0.5 when its dropped.
Using the following code, everything works fine if the game piece color is set to the base in frame 1 (red). If the game piece is created and the timeline moved to a frame other than 1, I throw an error when trying to access base.alpha (this would be the second, third, and fourth instances of base in the game piece timeline). Heres the strange part, this is only a problem when the game piece is first created and added to the display list. Once created, even after the error has been thrown, I can access the alpha of bases 2, 3, and 4 in the drag start/stop listeners. Heres a link to the work in progress, and the relevant sections of code (shortened for brevity, t1 is the top left piece on the pallet, others just repeat the same code):[URL]
I created a movieclip and linked it to a class called CustomButton. Inside the movie clip is a text field with name btnText. I then created a few buttons with this code:
Code: var newBtn:CustomButton = new CustomButton(); // set properties of new button newBtn.x = INIT_X;
[code]....
So far, so good. Everything works ok and the code sets the text of the new movieclip. Now, I wanted to actually write the CustomButton class and add some properties and eventually do other stuff with it and so I wrote this:
Code: package { import flash.display.MovieClip;
[code]....
On trying my script again, it gives me this error:
Code:1119: Access of possibly undefined property text through a reference with static type String
Movieclips created on the stage and instanced behave differently from dynamic movieclips in that they are destroyed when you go to the next frame (I have a stop on every frame). If I create that same movieclip dynamically then it will stay on the stage forever regardless if I go to the next frame or not. I understand that it needs to be removed from the display list but I can't find any event that is fired on a next frame basis. I could use onEnterFrame but at 30 fps, that's alot of overhead. The idea is to have all the code contained in my .as file.
The problem is that this code is in a frame and when I leave the frame the MovieClips I have created will still be there. I think this is because I'm creating a global MovieClip right? If so then is there a way to declare the MovieClips as local? [code]...
Can you addChild to a specific movieclip instance i.e. movieclip.name.addChild(movieclip).
I have built a 'for loop' to render a series of 'products'. The idea being to create a movieclip, load an image into this movieclip, assign a URL and later some text.[code]...
How do I attach data to a movie clip that is generated dynamically?
In my code below I create 3 green boxes. I want it to trace the sequence number of each box after it's clicked on, but I can't figure out how to make that happen.
Code: for (var i:Number=0; i<3; i++) { var nubox:MovieClip=new MovieClip(); nubox.graphics.beginFill(0x0FF000);

currently working on my first AS 3 project. The transition from AS 2 to AS 3 has been tough but rewarding. However, still fiddling with dynamically created objects though (using a database for my site-content). Here's my problem: If I dynamically create a MovieClip I can no longer access the main stage. Since I'm using a mousedrag interaction I need a global MouseUp Listener. If I try to access 'stage' or 'root' or 'parent' from within the dynamically created MovieClip the result is always 'null' instead of what's really there. Is there an easy way to access the main stage from within the created object?
I'm dynamically creating movieclips with dynamically created movieclips inside them and am having trouble with targeting them.
Below is a simplified example of what I'm trying to achieve, in the real file there are a lot more movieclips and I'm creating and naming them with a for loop.
This one is just one Sprite created inside another sprite. I can target the top level sprite named "testname". However when i try target the nested MC it throws an error.
The bottom couple of traces are just test MCs I've made to make sure i got the syntax right, on targeting nested movieclips.
PHP Code:
var holder:Sprite = new test1(); holder.name = "testname"; this.addChild(holder);
I am trying to use a for loop, to place 5 instances of the same movieclip on the stage. In the loop I used .name to give each movieclip a unique instance name. But when I try to reference one of those instance names in an event listener I get an error. Here is an example of what I am trying to do:
Quote:
var xPos:int = 120; var yPos:int = 60; for (var i:Number = 1; i<=5; i++) {

This code generates an error saying that the cStar2 property is undefined. In the example above, does the for loop create 5 copies of the movieclip starC_moov, and give them unique instance names cStar1, cStar2, cStar3, cStar4 and cStar5?

I'm having a problem while assigning variables into dynamically-created MovieClips. Here's a pseudo-code of what I'm trying to achieve.
[Code]....
I need the movie clips to contain their index values as a variable within them. I've tried several approaches, including declaring the variable names within the MC itself, but that doesn't work either.
I am trying to use the ENTER_FRAME event with a number of dynamically created movieclips and it is not working.The swf features a series of five clock faces that the user will select by hitting the appropriate button. Each clock has five unique movieclips to that season including a second hand, a minute hand, a main character, a seasonal clock face and a back ground, again, each of these MovieClips are different on each of the five clocks. So I have a series of five listeners for each of the buttons:
I have a gallery that reads an ms access database using asp and then loops through an array of records and duplicates an empty movieclip for each record. jpeg is then loaded into the movieclip and then a variable for the _x position is incremented and then the next one is loaded etc.I then use the same method to add the necessary labels for the images by duplicating a movieclip and adding a text fieldThis is all fine and produces a gallery of images but the problem comes when I try and position the labels according to the height of the image. I have tried every method I can think of to check the image attributes which are only available when it is fully loaded, but I keep getting a value of 0.
Code: stop(); // Set variable holding image folder path

Essentially, I've got a MC container that's created dynamically based off an XML file (basically for every <title></title> I've got, it makes a new "card"). Now within the context of each <title></title> grouping I've got <imgs></imgs> in which I specify the path to images that are related.All of that works perfectly, save for the external jpg files actually appearing on the stage. The MC I add them to does, but the external image doesn't.My problem is- I can't add the external images until they're completely loaded (or so it appears). The thumbnail BG I use is blank. So I know for a fact that the thumbnail BG isn't occluding the loaded thumbnails.
The following code adds 10 instances of circleMC to the stage. Inside circleMC is a dyn text field that increases in number from 1 - 10 so I have numbered circles on the stage.Each circle needs to open an infoBox which will contain variables unique to that box. I can't figure out how to address each infoBox. How would I say something like on circle1 set infoBox1.visible=true?
code: var jurNum:uint = 0; addBtn.addEventListener(MouseEvent.CLICK, onAdd); function onAdd(evt:MouseEvent):void {[code]........
