have a button on the stage that you called "myButt". Now suppose you want to change its size. You write:myButt._xscale = 25;Now suppose you don't know it's name, but you get the name from another variable:buttname = "myButt";How do you change its size then? in some compiler languages you can expand the string buttname into its value at compile time, with special flagging, such as:

I have drawn colored rods which I have placed in the library and have put one of each on the stage with instance names likeblueRod_mc, etc.I place them around with time-line code like
blueRod_mc.x = 300.0;I have now created an Actionscript class called Problem.I build a new object from Problem which I have called Riddle.But when I put blueRod_mc.x = 300.0 in a method (of Problem),I get the message that blueRod is not accessible.So I triedstage.blueRod_mc.x = 300.0;That did not work either.
I'd like to be able to access some objects which are on the stage before compile time (e.g. in my .fla file). I can do this fine from the document class using the names I've assigned to them, but I need to be able to do this from other classes (instantiated at runtime) too.
What is the best way to go about this? Can I use the stage variable (this isn't looking likely from what I've read so far) somehow? Or do I need to pass in references to these objects from my document class when I create the instances of the class that needs to access them?
I am trying to learn how classes can interact with each other and I came across a problem I can't solve. On my stage I have a MovieClip called "myMovieClip".

I have a structure display like this: (brackets shows the depths, within their parent)

I have a string array with a list of words,e.g. var textArray:Array = ["a1", "b2", "c3", "e5"]Then I also have an array with a list of buttons that are visible on my stage,e.g. var objectArray:Array = [a1_btn, b2_btn, c3_btn, d4_btn, e5_btn]m wanting to use actionscript to make the buttons that are writen in the text array to be visible onscreen, and the buttons that arn't written in the text array to be invisible.

But I keep getting an "Error #2030: End of file was encountered." This is (probably) because the class I'm serializing is too big for the "String" object type in AS3. Is there a limitless object for storing an array of characters (or better yet binary), or am I going to have to make my own class? (like one with an array of strings)
I was wondering if this concept is doable:
Scenario:
4 areas on 1 stage which are quite similar (eg webcamconference, each area has the same functions)
Buttonobjects are numbered(eg area 1 has playbutton1,mutebutton1,namebutton1,namelabel1, etc)
every area gets a close-Button which closes/shuts down the area.(close1,close2,close3...)i want to archive the following:
if(close1.isPressed){
function invisall(1);
}[code]....
this should do the trick via dynamic Nr at the end of each default button(eg playbutton)
but ofc
"playbutton1"._visible=false;
doesnt work because playbutton1 is still a String.how can i take the String as a Buttonname /ButtonObject? do i need to write an new function? this would destroy the purpose of less code. for now i will split the area into frames that i put on the stage.
- I have A.fla.
- A.fla includes buttons, movie clips and also B.swf is loaded in A.fla using a LOADER
- i want to access elements in A.fla, from the actionscript codes inside B.fla to modify those movie clips and buttons based on actions going on in B.swf
for instance, lets say there is a button X in A.fla, and there is a button Y in B.fla, B.swf is loaded into A.fla, and I want the button Y to erase button X when clicked.
general question: accessing elements in a stage, through a SWF file loaded into that stage.
In actionscript an object's property can be accesses in this way: object["propertyname"] Is something like this possible in c#, without using reflection?
View 2 RepliesI have an engine I created a while back that loads objects into a container based on XML data. A really quick example of the XML would be like this:
<level>
<object cname="enemies.Robot">
<pos x="200" y="400" layer="mobiles" />
</object><object cname="Player">
<pos x="12" y="89" layer="mobiles" />
</object></level>
I have a class Environment that has a method loadLevel(data:XML) which I parse the XML through, then the function runs through the XML finding all object nodes and uses getDefinitionByName to determine which Object I want to create based on object.@cname. From here, I have to manually define each property based on the XML like so:
obj.x = xml.pos.@x;
obj.y = xml.pos.@y;
etc.
I was wondering if there's an inbuilt method for setting a property based on a String. By this I mean something like so:
var mc:MovieClip = new MovieClip();
mc.someInbuiltFunctionThatSetsAProperty("alpha", 0.5);
This way I could change my XML to be more like so:
<object cname="Player">
<props>
<x>200</x>
<y>221</y>
<alpha>7834</alpha>
<health>Something</health>
<power>3</power>
</props></object>
And iterate through all the children of props to set all of my properties on the fly. I know if I create an Object and set properties within it like so:
var obj:Object = {
var1: "hello",
var2: "there",
name: "marty"
};
That you can then iterate through names/values using the for(String in Object) loop like this:
var i:String;
for(i in obj){
trace(i + ": " + obj[i]);
}
/**
* Output:
* var1: hello
* var2: there
* name: marty
*/
Surely there's a way, as here's an example of identifying a property using a String:
var ar:Array = [new MovieClip(), new MovieClip()];
ar.sortOn("alpha", Array.ASCENDING);
So just to make my question more to-the-point: I want to be able to get and set properties that I can identify using a String.
I've a general question on accessing a MovieClip by using a variable.Here's a super stripped down version of the code I'm trying to implement:

(this.parent as MovieClip).varString ?I have tried:
Code:
(this.parent as MovieClip).this[varString]
but it doesn't seem to work.
I'm working on a flash video player and I'm trying to figure out how to access something inside the constructor that I know is set but it keeps telling me its not.

now in the metadata function its giving me the error, "Access of undefined property video" Now, am I just completely not understanding how classes work or is this a common problem?
I want to access an object from a class in which it was not created in. I have a main class (A) in which I create and instantiate an object (of class B), from this class I can obviously do whatever I want with the object, no problem. The issue I'm having is another class (C) needs to access the object in question to change its x and y location values. Class C doesn't know what the instance of class B, created in class A, is; this doesn't surprise me, but I can't figure out how to allow class C to get access to what class A created.

the traces within the function return correct results, however when trace values of the arrays within the function and created by the xml are attempted results are returned 'undefined'.
Why can I not access arrays made in this way from outside of the function?
I have an object with an Array of objects inside. Each object has a name property. To scope it directly I would use:
ActionScript Code:
obj._arrayOfObjects[0]._object name; // trace returns the first object's name in the array
if you understand this so far then here is an easy question for you.

I'm writing a web based flash app that's written entirely in AS3. I have objects on the screen as part of a GUI. I would like the user to be able to resize the window, or make it full screen. I would like everything to auto-scale with the resize, but also remain in the same relative position on the stage.
View 1 RepliesIf 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?
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).

So I have a menu built inside of Flash CS4 that has a graphic for a background and five text fields that sit on it for menu options. The whole thing is saved as a movie clip in the library. The text fields all have instance names like infoBtn and mapBtn etc. and the menu is already on the stage and linked to it's own class in the library. My problem is accessing those text fields on the menu from the class. I keep getting "Error #1009: Cannot access a property or method of a null object reference." and the menu doesn't work. But if I trace the infoBtn.text in the class it outputs the text that is in the text field. So the code is accessing it but it's still not working?

I'm a seasoned AS2 developer who's been dragged kicking and screaming into the world of ActionScript 3.0. I'm working on revising an old project coded in AS2 that needs to be re-coded in AS3 and It's been slow going. I have a question regarding addChild (attachMovie) function. My scenario is as follows: I'm pulling data from an XML file that dynamically builds a scroll list from items in the library. Each item in the list has an individual button function attached to it. I'm generating my list just fine, but I can't access the items as individual buttons. Instead, it seems that the entire list has the properties of the last child added.

I have a movie clip on my scene with a number of objects all prefixed with a keyword 'build' (e.g. 'build8934', 'build4920') - is there any method, array or object that I can access that would give me access to a list of objects for that movie clip?I'm intending to loop through an add events to an instance which matches the prefix 'build' and set additional properties based off that instance.x.
View 2 RepliesI have (may be a simple solution needed) a problem with a class I've wrote. I've wrote a class named Navigation [URL] and in there I make all the buttons for the navigation. Next to that I have a Ipage class [URL] and in there I have all the pages stored. When I click on a button, the Navigation Class is called and tries to access the public function ChangePage in the Ipage class. In the ChangePage function I trace if the function is called and the trace comes back. So it works... BUT if I want to access another object it's not working. I can't even set sprites on visible = false.

It is a 3 frame game, 1st frame is the start button, 2nd frame is the game, 3rd frame is the score and play again. 1st frame: Buttons to go to the second frame 2nd Frame: timer to count 30 seconds of play time 3rd frame: buttons to play again. ScoreValue is a dynamic textbox in the last frame of the game. It records the points based on size the size scale of the bubble, and should be change based on the amount of bubbles the player has popped.

Im getting this as output in my program, does any one know why? Fonts should be embedded for any text that may be edited at runtime, other than text with the "Use Device Fonts" setting. Use the Text > Font Embedding command to embed fonts.
I'm currently working on a game. I'm breaking down each piece of the game into individual classes and movieclips. The intro begins by going to the main menu which is a MC in my fla library. This is called through the document class. then all actions the main menu MC performs are commanded through the MainMenu class. When starting the actual game, MainMenu calls a function from the document class, after it is removed from the stage, that puts an empty movieclip called Level on the stage.
