ActionScript 3.0 :: Accessing Values From Child Elements?
Jul 9, 2009
I have a movieclip, with the instance name SizingBox, on the main timeline. Within that mc, I have a Slider component, with the instance name Sizer. I want to declare an action listener on the main timeline which will listen to changes for Sizer and do something based on the current value of the slider.In AS2 this was really easy, but I cannot seem to figure it out for AS3.
Code:
var X = SizingBox.Sizer.value;
this code gives an error.
I am working on a information visualization project that involves visualizing json data from online forums. The problem that I'm having is that I'm not able to access all of the values of elements the json. Here is my Schema:
[{"course": "compsci 101", "forums": { "forum": { "forum_title": "Week 11 - Cable and the Specialization of Television", "forum_word_count": "1000", [Code] .....
I tested and the json is valid but when I run it with this code it only is able to pull the last value (Week 2 Discussion 1 - Cable and Broadcast Television). for (key in tuples) { trace("forum title: "+ tuples[key].forums.forum.forum_title); } So, my question is, why isn't it tracing all of the values for the forum title? and what do I need to change to access those values?
I am a bit of a noob, and I'm having a problem. I had posted about this before but I think I was explaining what I need to do in way to much of a complicated manner so I'm going to try and simplify this a bit. I have 5 swf's.
After quite some time I finally decided to pick up Flash again, this time taking the OOP route. I'm a bit rusty though, so I'm stuck on something pretty basic.Here's my Layout of relevant objects and scripts:
As you might've guessed, what I'm trying to do is set the gunAmmo.text property from within my pistol class. I've tried using MovieClip(root).gunAmmo, stage, etc., but neither seems to be working. I sort of get why, but I don't know what the correct syntax is. (And yes, the TF's instance name has been set correctly.
look at this code and talk a bit about lines 6 through 11.What is the relationship between those values and the elements? And how about those hex addresses?
Is it possible in Flash 8 accessing from the linkage class, associated to a component, the graphics elements (for instance, a standard UI component, like a tree or a comboBox) that are on the movieclip this class refers to?
I'm trying to link a clip to a class, and it goes well until I try to access MovieClips or TextFields placed on the stage within that clip from code in the class. My code is below; there is a TextField called output_txt on the stage within this clip.
class Main extends MovieClip{ public function Main() { //trace("123"); <--if I replace the line below with this, it traces nicely output_txt.text = "123"; stop(); } }
I've used the GUI to create a rectangle that I turned into a button symbol (SimpleButton). I then edited the button so that it had 4 different button states and a text layer on top. I then created a class definition file for this object so that I could dynamically change the label text (the text layer) when adding instances of this button to the stage.
I was able to create and link a class file (DynamicButton.as) just fine, but when I try to access the text field that I created on the button, I get the error:
"Access of possibly undefined property btnLabel through a reference with static type com.examples:DynamicButton."
when i couldn't get that to work, I decided I'd try adding the TextField directly within the class definition file, using the following code:
The problem is that I can't seem to add the TextField to the SimpleButton, as it's not a display object. So, I tried adding it to the parent of the simple button (and I figured, I'd just place it exactly above the button). But then I get a "null object reference." error.
is there a way to access GUI-created elements from w/i a class definition file? How would I add the TextField to the button using only AS3 inside of a my class definition file?
I have an XML file that I have imported into an ArrayCollection. I can get all child elements of the XML (ArrayCollection), but can't for the life of me get to the attribute. Where does the array collection put it?
Anyone know how to animate the size/position of child elements of a layout in Flex 4 ?
I have a list component with a custom layout. I want when I change the positions of the child elements I want them to animate their move to the new positions.
I just read the tutorial "Finding Values in an Array". Sure, the code works, but that's only because we are searching arrays the contain a small number of elements. Suppose we have n elements in an array. To search that array for a particular element we may have to do n comparisons. If the array we are searching contains 10 million elements, we have a problem; can you imagine doing "if (this == that)" 10 million times? There's got to be a better way to search the array. Or perhaps we shouldn't use arrays to store the information.
I am trying to develeop a Graph Structure with drag and drop features in Flex. I have to connect various components/children on the canvas. Once i drag n drop the components on the canvas, i am using SystemManager event handlers to draw connectors between the components. But, as i click on one component and drag the mouse, the line is drawn on the canvas as long as my mouse stays only on the canvas. If the mouse moves over a component/child(that has been dragged and dropped onto the canvas), the line is drawn to the origin of the canvas from the first clicked component. How shud i recognize the component when i move my mouse over the component? I want the line to be drawn connecting the components once my mouseup event is called.
I have a control which contains many child elements (about 1000), and I need to sort them.Now I doing that like this:
_elements.sortOn(...);
for (var i: int = 0; i < _elements.length; i++) { setItemIndex(_childItems[_elements[i].id], i); } _childElement - object that contains UI-child elements, which i need to sort (key of the dictionary is an identifier from data-object _elements - array contains data-objects
But this is too slow! How to reorder the childs by my criteria as fast as possible?
I'm working on a simple task/calendar tool where tasks can be added dynamically to a canvas. Here is the main application as defined in Main.mxml, which is essentially just a Canvas and a button for adding a task:
The problem is that when I add a Task instance to the Canvas, the children (the button and label) don't appear. I tried setting creationPolicy="all" on both the Canvas and the BorderContainer, but it still didn't work. I've read a bunch of posts about people having issues accessing members of their class before the class is fully loading, but all I want to do is SEE that Label and Button show up inside the BorderContainer.
Ok every time I think I understand the DisplayObject model i find something else that seems like it should work but fails. Am I correct that if I create a sprite then create another sprite and add it as a child the original parent sprite will show a height of 0... In my case i have three classes that all extend Sprite and each one is creating the next with the "youngest child" being a class that adds an image to its "stage". I can see the image height fine but its holder does not nor does its holders parent... im having a real moment here as I debate if im just stupid and missing the obvious way to do this or if I really have to add a bunch of getters and setters to see the height that includes children.Maybe I am thinking of this too much like a CSS block element but it just seems like it should work this way...for example
I'm having such trouble accessing the value of the selected radio button in a group.I put 5 radio buttons on the stage and gave them all the groupName of 'Question1' in the component inspector. They each have their own instance names and a value which is also set in the component inspector.When I go to access the group (via Test Movie) and check which value is selected I get this error:
'Access of undefined property Question1'Here's the code I'm using:
var Radio1:String = new String();Radio1 = Question1.selection.value; SubmitBtn.addEventListener(MouseEvent.CLICK, clickHandler); function clickHandler(eventObj:MouseEvent):void { trace("clicked"); trace(Radio1);}
Other problems I'm having with this code is the flash player doesn't believe the value of the radio object is a string...so what is the data type of the value property?
This will parse child elements of the <text-block> but will not work with <ul> as it has its own child elements <li>. I guess this could be accomplished with yet another loop but I wanted to check to see if there was another simpler way.
The issue I am having is that I have no idea how to access the Children of another MovieClip. I have 2 MovieClip's, storeFront, at frame 25, and reviewPage, at frame 60. storeFront contains a vector, cart, and I need to access it from reviewPage.
I have tried...
var appRoot:MovieClip = parent as MovieClip; buff = appRoot.getChildAt(30); review = buff.cart;
I have a flex application that dynamically loads swfs and I want to to use a set of color pickers in an external component within the application to determine a color array in the loaded swf.
I figured that I can use a new array of the colorPickers, i.e.
public var colors:Array = new Array [ cp01.selectedColor, cp02.selectedColor, cp03.selectedColor, cp04.selectedColor, cp05.selectedColor]
Is it possible for the swf to read the Array if it's set up like that? If so what would I put into the swf to get it? If not what do I need to do?
I have a swf named home.swf on the stage of home.swf I've added a Sprite with this code var onStage:bc_sprite = new bc_sprite();addChild(onStage);another swf called menu.swf loads home.swf into a loader which is added to a MovieClip named currentPage which is on the stage thusly.currentPage.addChild(swfLoader);
I have a video gallery that generates a menu from xml.I first create a container then add textfields as menu items to the container I have listeners for mouse OVER on OFF for each menu item as welll as a function to change the text color ON CLICK.What I need to do is figure out how to switch a previously clicked menu item's text color back to "OFF" color when a new menu item is clicked But I Can not figure out how to traverse the display heiracrhy to get to the textField's color in all the other menu items.
heres the function:
ActionScript Code: //create Moviclip to hold menu function createMenuContainer():void {
[code]....
so the video menu item's heirachy is some thing like
but of course this does not work. I think my logic is reasonably sound I just not sure of the correct syntax to get at the textField.textColor of all the other menu items that ARE NOT clicked on the Mouse Click Event of a menu item that is clicked.
I have a parent swf which loads a child swf. The. Child swf is a game and when. It finishes, I need to access the score from the parent swf. How is this possible....
i have to make a drag and drop thingy in actionscript 3.0. Now we had another actionscript project before and then i had some extra classes but most things i put in the main class and it was all working fine. Someone told me that i put too much in my main class and that i should make more classes like a class for every object you interact with. Dont know if hes right but he acted like he was.
Now back to the problem. I made a main class connected directly to my fla in its properties. Then i made another class for the game itself, cause maybe it needs an intro and other things so i want to separate them in their own classes and start them with the main class. now in the class for the game itself i want to be able to click an object with the mouse. I was just testing with a trace. When i click the object it only traces like 1/20 clicks i make, tryed alot of things, when i put the same code in the main class with stage.addEvent blabla it will respond every time but as soon as i try to put in the class for my game it only responds like 1/20 times i click. Wth?
Now i can put all my code in the main class again and make another 1000 line code with a couple of other small classes but this time i want to do it right so what am i doing wrong? Heres some code too
This is the main class dressUp is the game class, it doesnt do much just define the game class and change the mouse pointer.
EDIT: We work in a project group so another reason i want to make alot classes is so we can work on different classes separately. But i promised to have this done this weekend and there not so good in actionscript either.
Personally, I prefer just having separate classes fo each object then bring them all together at compile-time, but someone I know had a problem with his game which had a lot of embeded movieclips already on the stage.
how I could go about accessing the Sprite "lmao" which is on Frame 2 of the "omg" MovieClip?
