ActionScript 2.0 :: Function To Discover What Movieclip It Exists In?
Dec 30, 2004
I have done some reading up on it and could use some further clarification if anyone has a few moments to enlighten me. I would like to understand how paths work inside a function. Question 1: Is it possible for a function to discover what movieclip it exists in? When i trace(this) within my actionscripted function it returns object Object. (sorry code is on another machine)
Question 2: When I am attaching a function to _level0.myMainClip.mySubClip from _level0 timeline in actionscript and I use "this" within that function am I refeering to _level0.myMainClip.mySubclip? or the function within that movieclip or _level0 since that is where I am creating the function?
In my scenario, a user visits my webpage and is prompted to select a Music folder on her local filesystem. The web app crawls the folder and indexes it, reading all the metadata from the songs.After a few moments, the index is presented in the page's HTML and the user chooses a song to play.I can't expect to do this with pure Javascript, can I? I imagine I'll have to rely on a heavyweight object (an embedded Flash movie, a Java Web Start, an AIR app, or a Silverlight app) to scan the files and play them.
I feel confident that I could do this with a clunky Java Web Start; but is it possible with an embedded Flash movie? I'm trying to make the process as clean and streamlined as possible for the user.How should I proceed?Which framework can make this dream a reality?And how many permissions screens will the user be forced to wade through?
1- Variable Scope : Accessibility and existence are used almost interchangeably in various documents I've read. I'd like to know if a local variable physically exists (in memory) outside of the function it was declared in, and is not accessible from other methods, or if its existence ceases outside the function.
2- Classes : When do you create an instance of a class versus importing it only, specifically in the case of classes used only as say, calculators ?
I have a movieclip created with the following code:
var thumbContainer:MovieClip = new MovieClip(); thumbContainer.name = "thumbContainer"; stage.addChild (thumbContainer);
If the window gets larger/smaller I want everything back in place. So I have an stage Event Listener. Now I want to see if this mc exists to put back in place. I've tried different ways but keep getting an error that does not exist.1120: Access of undefined property thumbContainer.
if (this.getChildByName("thumbContainer") != null) { trace("exists") }
In AS2, I'd create a movieclip and give it an instance name. Then all I'd have to do for example is, check if _root["myinstance"+i] == undefined but in AS3, if i'm dynamically creating 10 movieclips, how do i check to see if it already exists?
What can I use to check if a movieclip has been added to the stage yet without flash throwing a bunch of errors at me? For example, I have a movieclip with the instance name(mcONE) on my stage. And I'm currently using this bit of code to check if it's on the stage
tl;dr:Using MTASC, How can I take a MovieClip that exists on stage and interface with it through a custom class? I'm a UI/UX designer and interface engineer, and I've recently been trying to improve my development workflow. I've been trying to achieve the following workflow:Create the UI in Adobe IllustratorImport the UI into Adobe FlashSet up MovieClips to allow interactivity on the stageExport the finalized design as an .swfWrite code to interface with the various parts of the UIInject the code into the precompiled .swf using MTASCI can do all of the above, but I've been having problems when it comes to writing the code. I'd like to write object-oriented code as much as possible, but I can't seem to link my custom classes to anything that starts on the stage. How can I take a MovieClip that exists on stage and interface with it through a custom class using the MTASC?
How can I check if the stage contains a movieclip on a specific x and y location on the stage?I'm building a colour-guessing game. The purpose is to walk a path through a generated field of hexagons, each assigned a random colour (yellow, red, blue or green), based on what soundfile you hear. So if you hear "yellow", you have to click a yellow tile etc.But because I want it to be a path, and the colours of the tiles are randomly generated, I have to check which colours border the currently active tile. I literally have no idea how to do this. I thought this might work but it doesnt:
if ((this.tile.y == (event.currentTarget.y - 64)) != null) { //add the colour of this tile to array }
I am trying to activate a rollOver-function when the mouse rolls over a movieclip inside of a movieclip.On the main window (root), first you rollOver a button where a window shows up with more options (movieclips).From stage, my first movieclip is called "catapultas_read_more" which leads to amother movieclip called "pic1_mc". The label that is going to play when mouse over on pic1_mc is "rollOn".I tried this.gotoAndPlay("rollOn); directly inserted to the movieclip, but the movieclip inside pic1_mc never starts
I am trying to access the variable myParentVariable within the function myParentFunction() from the MovieClip's myMovieClip_mc function myMovieClipFunction().
I know that It works if I declare the variable myParentVariable outside of the myParentFunction() but I don't really want to do that
main timeline //-------------------------------------------------------------------- --- myParentFunction(); function myParentFunction():void
I have a gallery loading jpegs from an xml file into a mc called mainPicArea, on frame 5. I have other content on frames 1,2,3,4,6,7.I want to run an if statement to check whether mainPicAreaexists and if it does, then run a removeChild(mainPicArea), and if not do nothing.
code: if (MovieClip.mainPicArea){ trace("exists"); //removeChild(mainPicArea);
[code]....
this is my code. When I test, it comes back with the trace "doesent exist", even though it does exist.
Is there a way to see if a class exists? something like:
if( MyClass exist in the Library or has been imported in to the class ){ var myClass = new MyClass() addChild(myClass); }else{ trace("MyClass doesn't exist") }
I'm not trying to see if it exists on the stage just want to know if I have access to it.
Im gonna make an image gallery that loads thumbnails 1.jpg, 2.jpg 3.jpg..etc... into thumbnail mc's it creates, and when it gets to a number of a file that doesnt exist i want it to stop making thumbnail mc's. What AS could i use. As of right now it trys to load the jpg that doesnt exist and the preloader keeps going forever.
My page has 2 tab menus. When the page first loads, it defaults to the first tab, but when the second tab is hit, an image is loaded to the stage. I want to remove the image from the stage once the first tab is hit again.I keep getting the error "Access of undefined property Image1" but the whole point is to check if this child exists with the if statement.
//Tab 1 if (Image1 != undefined) { stage.removeChild(Image1);
I have a Dynamic text field embedded into a movie clip on the same frame different layer there is some action script. A series of If statements Which is basically to see if text field contains text so if it dosent contains text I can assign text to the text box
There is no text. Yet the if statement is false. Is this a logic error or is there a better method of achieving this PS i have tried orderMenu_mc.Item2_txt.text.length == 0 which also evaluates to false when there is no text in the field.
I am working on a software which takes .ppt as its input and produces .swf file as its output.
When I was dealing with fonts, I found there is slight difference between the representation of the text in .ppt and .swf though the font name and size are same in both.
The difference increses when I make the text bold or italic or both.
I want to know why such differerence exits?
And what should I do to make the.swf font representation same as that of .ppt?
I have an input field that asks for a .swf name - you enter the name, hit SUBMIT, and Flash loads that .swf onto the screen.I've coded for an error to appear if the user doesn't input anything, but how to I test to see if the swf exists, and if not, return an error?I have a function called onSwfLoad that runs when the swf loader finishes, triggered by anEvent.COMPLETE in the swf loader event listener - is there something I can put in an if statement there to test if the swf loader found a file?
I have a Rect object that I'd like to create and set its properties only once. After that, I want to just modify its properties since it already exists. This is my general idea
if(theRect == undefined){ Alert.show("creating"); var theRect:Rect = new Rect();[code].............
but can't get the desired effect. Everytime this code block runs, and depending on which version I've used, it either gives me a "can't access null object" error or the if statement always evaluates to true and creates a new Rect object and I get the "creating" Alert. What's the right way of creating that Rect but only if doesn't exist?
