Actionscript 3.0 :: Create Variable That References A MovieClip?
Aug 9, 2009
I am just starting to learn Flash. I am trying to make a "simple" Flash menubar to add to a basic html/css site I am building, as a learning project. I figured out how to make the navigation "buttons" using frame labels and event listeners. All the nav buttons will be identical, except for an image and the link destination. I know enough about ECMA based code to be dangerous to myself, so rather than make 7 individual buttons, each with there own AS and objects, I am wanting to make it more efficient by reusing the redundant information.
This is the logic than I am trying to use:
Create a generic button named "button_mc" that has a child which is a variable instead of actually pointing to a specific object. Then, create 7 different instances of that object (button1, button2, etc), and in each instance assign the proper image (contained in a mc) to the variable that is in the parent object.The problem I am having, is that I can't figure out how to make a variable that will reference a movieclip or graphic.[code]...

I've got a 15x3 grid of dynamic text fields in an object called "textbox" that I want to reference through a for loop, so I don't have to have 45 lines of code for assigning stuff to those fields.I have each dynamic field named by their placement in the grid, so, c0a, c0b, c0c, c1a, c1b, c1c, etc.I can also name them c00, c01, c02, if necessary.
I tried:
for (i=0; i<15; i++) {
textbox.c[i]a.text = "Cell " + i + " A";
textbox.c[i]b.text = "Cell " + i + " B";
textbox.c[i]c.text = "Cell " + i + " C";
}
but that gives me a syntax error.I also tried naming them c00, c01, c02, c10, c11, c12, etc., so I could do a double nested loop:
for (i=0; i<15; i++) {
for (n=0; n<3; n++) {
textbox.c[i][n].text = "Cell " + i + n;
}
}
but that gives me a syntax error too.So, is there a way to access all of these with a for loop, or am I going to have to do it the long way?

I need to create two combo boxes that are populated by an XML file. In the first combo box there are 13 choices and depending on what the user selects I need to populate the second combo box with the correct information. Now I can create the first combo box just fine but when I try to dynamically create the XML file name for the second combo box it doesn�t seem to work. What I am doing so far is taking the data from the first combo box and adding the quotes and .xml with this piece of code:
PHP Code:
pModCombo = '"'+event_obj.target.selectedItem.data+"Combo"+".xml"+'"';
pModComboXML = new XML();
pModComboXML.ignoreWhite = true;
pModComboXML.load(pModCombo);
If you trace that code it creates the file name just fine however the xml file will not load. If I replace that code with the normal xml code like this:
PHP Code:
pModComboXML = new XML();
pModComboXML.ignoreWhite = true;
pModComboXML.load("new.xml");
The second xml file seems to load just fine. However, if I create an if statement with all the different xml file names I will have to update the swf every time I add a new choice in the first combo box. So my question is does anyone know how to dynamically create the xml file name?
PHP Code:
pmComboXML = new XML();
pmComboXML.ignoreWhite = true;
pmComboXML.load("brands combo.xml");

I want to create several "buttons" (which are actually MovieClips) that are all identical apart from an image and the link. My thought was to create a movieclip button that contains a var that will represent a movieclip, then in each instance of the movieclip button set that variable to be the movieclip image that will correspond to the button.
Geez my query seems so simple until I try and put it into words...The gist of it is, how do I name a movie clip variable? Something like, in the main movieclip, instead of inserting a specific image into the movieclip, insert a variable named innerImage, then in each instance of that movieclip name the image to be inserted by specifying the variable
var innerImage:MovieClip = the movieclip I want for this instance.
If the var was a number, it would just be:
var innerImage:number = 4;
If the var was a string:
var innerImage:string = "word";
So for a movieclip:
var innerImage:MovieClip = ???

I have a files that has movie clips and nested movie clips on the stage. I am now writing a class and want to give the MCs event handlers and other properties.
When I do something like the following: myMC_mc.MyOtherMC_mc.mouseEnabled = false;
I get the error: 1120: Access of undefined property myMC_mc.
I added this to the top of my class and it seems to take away the error, but I thought this was not needed in AS3 anymore.
private var myMC_mc:MovieClip;
private var myMC_mc.MyOtherMC_mc:MovieClip;
What do I have to do to not get the error? How is this done right?

I have a movie clip in which I have a number of sub movieclips. The number of sub movieclips can vary, so I would like to keep track of them in an array. I am doing that like so:[code]The trace seems fine, showing the names of the correct sub movieclips, but when I try to change the alpha I get this error: TypeError: Error #1009: Cannot access a property or method of a null object reference.

I'm loading a bunch of images into my AS2 flash movie, and I've encountered some strangeness.
Roughly, my code looks like this:
function doTheLoading()
{
m_imageClips = [];
[Code].....
why does my array content seem to change when in the onLoadComplete call? If the array is out of scope, then why can I still see the length of the array and determine the type of the contents?

Is it possible to create one or several instances of a movieclip from the library with variable names
my1_mc
my2 _mc
.........
my5_mc
so that I can make a function that will use the name of any of these movieclips.

I built a custom designed checkBox. The movieclip is in the libary and dragged onto the timeline of my .swf. I'm using CS4 & AS3. I'm using procedural AS3 instead of OO AS3.The checkbox movieclip has a child movieclip inside of it so I can apply a drop shadow filter to some of the graphics .When I put an eventlistener on the custom checkbox it works fine but when I try to reference the checkbox movieclip inside the eventlistener function, the event.target.name is referring to the child movieclip (just a graphic with a drop shadow filter).From my reading it looks like the function propogates down to the child movieclip but I don't want it to do that.How do I reference the parent movieclip? or
B. stop the eventlistener from propogating down to the child movieclip?
I tried using stopPropagation(); but it didn't stop the function event.target.name from trickling down to the child movieclip.Here's what AS3 looks like.The trace statement displays "step3_mc.cbEmail_mc.instance25"instead of what I need "step3_mc.cbEmail_mc"
step3_mc.cbEmail_mc.addEventListener(MouseEvent.CLICK, fnc_cbClick);step3_mc.cbAgree_mc.addEventListener(MouseEvent.CLICK, fnc_cbClick);

f you know PHP...then you know that you can create a string variable...and then use the value of that variable to declare another variable. like this:
PHP Code:
<?php$foo = "haha";$i{$foo} = "success";print $i{haha};?>
and it would display "success"...or like this:
PHP Code:
<?php$foo = "haha";$$foo = "success";print $haha;?>
and it would also display "success".

I'm currently working on an advanced preloader and i'm creating loads of different variables etc. based on the percentage loaded. I need the variables to be named Number + percentage, so in the end I will have Number1, Number2, Number3, Number4 etc. How can I create variable names using my percentage variable? Can't seem to find anything that answers my question.

I want to be able to have a number displayed on the screen that when one of the arrows next to it (up/down) is clicked it adds 1 to the original number (lets say 72). Then when they click the "save" button that really just takes them to the next frame (or a frame somewhere else in the movie), which is a confirmation page, I want the number they ended at to display on the confirmation screen.
I'm thinking that it is partially because I don't know what to search for.I know I have to create a variable and get the button to add one to that variable.

I want to declare a variable on the main timeline that can be called from anywhere in my movie. So, _global var should be the right approach. I want to declare a movie clip 'MC1' "open", or "closed" so that when it is revisited, my flash file knows the user has been there before and performs a different task from the one it does when 'MC1' was first encountered. So, i need a 'if' statement to run from the variable, when the playhead encounters the movieClip.

I have been banging my head against a brick wall regarding the following problem which must be very simple to fix, just can't see the answer.I have a class assigned to a movieclip called canvas. The class is called drawClass. I have called the instance of canvas on the stage 'drawingCanvas'.When I trace "drawingCanvas" I get object drawClass] which is fine. Tracing drawingCanvas.name gets me the instance name 'drawingCanvas'.This is a String variable.Basically what I am trying to do is pass the MovieClip name to another class. In my example the class 'toolBar', which can then interact with the MovieClip.
The problem is passing 'drawingCanvas.name' results in a String, so I get an error saying :TypeError: Error #1034: Type Coercion failed: cannot convert "canvasArea" to flash.display.MovieClip.I can't for love or money find a way to convert a String variable to a MovieClip variable! I have the name of the MovieClip, I just need to tell the toolbar class. But I can't find a way of doing this as the instance on stage is an object of drawingClass, not a MovieClip (unless MovieClips with attached classes are not treated as standard MovieClips?).

I am brand new to AS3 and just about muddled through with AS2. I have a problem which should have a simple solution but everything I try gives errors.I had a load of buttons on the main timline which worked fine. I have moved a load of them into another movieclip called flyoutMenu. Now none work and I get the error:Error #1065: Variable about is not defined.This is the code stripped down to one button:[code]

This is something I'm experimenting with, but haven't seemed to figure out... I have several MovieClips, basically the same, only different colors. As each one plays, I'd like it to "overlap" whichever one is already there. Right now I have each button linked to a gotoAndPlay function, but I don't think that will ever get me what I want. You can see how I have it now here: [URL]
Instead of having the content MovieClip go back to all white when a button is clicked, I'd like the preivious one to remain, and get "covered up" by the new one. You continue to see the old color, and the new color overlaps it. I have a feeling I need to use a variable and then addChild, with a removeChild for the old MovieClip after the new MovieClip has loaded, but I'm not getting any good results yet.

I have a loop that creates movie clips where the movie clips are named mc_+ x for say x = 1 to 10 so the movieclips are called mc_1, mc_2.....mc_10.
What I need to do is the know which one of the movieclips is clicked on but more importantly the number i.e if movieclip mc_2 is clicked on then I need to use the value 2.
At the moment I am sending the value of x to be displayed in a text box within each movieclip:
_root.search.textfield.text = x;
Then I have a piece of actionscript that uses the value of x but I don't seem to be able to "re-read" the value of x back with:
var t = _root.search.textfield.text;
what I want is t = x is it to do with strings and number variables?is it possible to send the variable x to each movieclip so that it can be called from within each movieclip instead?

My goal with this actionscript is to create a new movieclip for each top-level XML node and include in the movieclip two separate textfields, an image, extend the movieclips to two row if necessary, rotate each movieclip differently depending its parity and add a hover event based on the movieclips instance name. I have achieved each goal except for the hover bit. The reason I cant access the instance name outside of the for loop is because the instance name only lasts for duration of the loop. Here is my current code (at pastie address).

This is the third thread I've written for my current project (1st was answered perfectly, 2nd failed [but I still figured it out anyways]) but I'm not sure if there is a solution to this problem. I can't really explain my problem, so once again I've included a helpful animation to show you what I mean. Bear in mind that the pale-blue box represents the movie clip's borders, and those borders are usually changed to include the animation (instead of the borders moving with the animation, the borders get bigger).
For the animation problem, I've already got a solution: create an invisible movie clip that has the exact size and shape of the animated movie clip and make it follow the movie clip as it animates, and make the hitTest check the invisible movie clip instead of the animated one. As for the rotation problem, well, I don't know how to fix it. Is there a way to change that?

Why would you create a button within a movieclip instead of just having a movieclip? Does the 2 different types give you more scripting options?

I'm writing an application where I have many objects (data models) that are identified by a unique String ID that every such object possesses and these objects can refer to each other by their IDs.So far so good but now I need to keep track of which object keeps a reference to another object and of course there are cases where an object references (or is referenced by) more than one other object and I was wondering what would be the best method to store these references? In a simple map data structure I could just map one object's ID to another but as mentioned there are cases where an object can hold a ref to an arbitrary amount of other objects

Types like Movieclip , String, Object act as references when declared and defined, while types like int, Number are primitives. Why such difference has been made. Why not all of them can be primitives ?

I'm using the CSS object (TextField.StyleSheet) to format my dynamic text, which is loaded from an XML doc. I tried referencing more than one class, like <span class="body bluetext">. However, it doesn't seem to work because it ignores the first syle(s) and only applies the last one in the list. I'm guessing Flash doesn't support this (since they're CSS support is already very weak). Just want to make sure I'm not doing something wrong.
