ActionScript 3.0 :: Creating Instances At Runtime?
Sep 19, 2009
Been struggling with the basics of creating instances at runtime. I needed to implement an XML video player and even though the client has supplied a component that they liked and it works fine, i cant turn it off as im not sure how the thing works. Basically the timeline hits a keyframe and stops. It runs the code to make the player popup but once the user has exited, the player stays on.If the function creates an instance for flv playback... how do i tell it to stop?
function below
function makePlayer ():void {
my_player = new FLVPlayback();[code].........
im develloping an application for create a layout of advertising newspaper. the user can set the number of pages, and create rectangles represanting the adverts, then drag them and place them into the the representation of the page.the display list is as follow: on the main stage there is inputs textfields and a button that create the pages according to the number that the user typed.Then instances of the pages are created (MC Page in the lybrary exported for AS as Page and i have a class Page as well). Inside this clip Page i have my tools for create the rectangles and drag and place.....As well as the instances of my pages are created, button(1 for each Page) are also created. NOTE that Page and button are in the main stage My probleme is that i want my button to change the depth of is related page for it can be on top or alpha at 100% or the visibilty to true, but my button doesnt find the instance name of the pages at the export because they are not yet created.
I'm trying to embed fonts at runtime in actionscript and it somewhat works. I can embed fonts by either using the embed tag or by loading a font library asset with a linkage name and use it with a new TextField. However, a textfield that exists on a movie clip already does not have the embedded font and is missing characters.
A quick example in code (textInstance exists on the movieclip): var embeddedFonts = Font.enumerateFonts(); //Shows embedded font var textFormat:TextFormat = textInstance.getTextFormat(); textInstance.text = "Don't be lazy"; //missing characters
[Code].....
I want to embed the font at runtime and I'm loading multiple SWFs and I don't want to embed the font in each SWF.
How can we create an SWF out of runtime created objects in an SWF.OrSaving Runtime created objects.The idea is to create an interface in flash that can be used to create some animations , saved , and later used.
I'm having trouble creating instances of an object, I want a random number to be generated and then based on the number which was choosen create an instance of an object in one of four positions.The problem I'm having is, my instances are generated fine but there is one that keeps jumping to x 0 and y 0.[code]
I'm trying to create a vertical column of images in a mc that can be clicked. I've added listeners to reposition them once they load, but right now they are overwriting each other. I'm not sure how to rename the object and listener vars for each iteration. [code]...
I'm trying to create a container movie clip, then inside that, create several other movieclips with an image in each and display them with an offset x.It does the offsetting but only displays the last one at the last x.When i dont put the clips in a container it works fine. but i want them in the container so that i can movie the container around on a press.
Heres the code:
var itemsArray = new Array("pic1.jpg", "pic2.jpg", "pic3.jpg", "pic4.jpg"); var clipArray = new Array(); _root.createEmptyMovieClip("carousel", this.getNextHighestDepth());
I'm loading a set of images and text from an XML file.I have the images loading into empty MovieClips created dynamically using 'createEmptyMovieClip', and I can get the text into dynamic textboxes that already exist on the timeline, but this isn't exactly what I want.
What I wan't to do, is to pull the text from the XML directly into dynamic textboxes at runtime, in the same way as the images.I've read today about 'createEmptyTextField', but I can't get it to work.
Any way to take the contents of an array, which is full of texttype, and use them to create a stack of buttons. Now the actual text I have in the array will change every time the program is run. For example, let's say my array is ["apples","oranges","pears"]. I want to create three buttons (in this example) so that it appears apples oranges pears And when you click on "apples", it takes you to the corresponding "apples" webpage ("_blank").
I am writing some code that needs to be very efficient, yet flexible. This is in a class and when the class gets initialized a function is setup. I want this function to run straight through without doing any time-consuming things such as calling other functions or routines, or doing any if/else logic/branching. Now I know that you can setup a function at anytime during runtime such as:
Code: var myFunction:Function = function() {trace('HELLO!')}
But what I am trying to do is to try and append code to a function based on logic, yet I don't want the function to be deciding this logic when it is running as it will only need deciding when the function is created.... imagine if it were a string it would be something like myFunction+="do somethingelse;" which would be the same as having initially setup myFunction as such:
Code: var myFunction = function() {do something; do somethingelse;}
With this I seem to be having no luck Here's an example where I setup the most compact/efficient function at runtime depending on what I want the function to do. Now this was fairly simple because when we create the function there are only a few possible variations, but I need someway of doing a function+= as my real code has quite a few variations and it would be a nightmare have a zillion if/else branches. REMEMBER I do not want any logic/decisions in the function itself as it to be the most efficient the function must be as compact as possible and run straight-through.
Code: var dynamicFunction:Function; // // Setup the dynamic function & call it // In this example outputs "Hello Jim" & "Goodbye Jim" dynamicFunction = CrapSetupRoutine(true, true, "Jim");
[code]....
P.S. I knew the += would never work as this is a function and not a string. But at least if you think of the function as a string you'll get what I'm trying to do....
I'm having trouble creating multiple instances of one movieclip. I've got an array set up that loads photos into flash and places them in a grid (sort of). I want those photos to have outlines around them. So, i created an outline. Now, when i try to place it on all of the photos, it will run through them and only apply itself to the latest photo (one instance overwrites the others). How do i make multiples of the outline?
basically i want to create ten balls on the stage. I have a balls.as file which uses the drawing api to create a circle within it. also within the balls.as file there is a public variable.[code]how would i go about finding out: if you click one of the balls it traces that balls life.
I am working on a project in which I need to create a bunch of buttons.. all need to look the same with different text on the button.. rather then making each button separate in my library I would like to make one and create instances of the one button. I have created a button with a text field on top named txtLabel with a default text of "Label Here". I have dragged an instance of the button onto the stage and named it btnHome btnHome.txtLabel.text = "Home"; d Does not work..
I get the following error TypeError: Error #1009: Cannot access a property or method of a null object reference. at MyProject_fla::MainTimeline/frame1()
var sp:Sprite = new Sprite(); sp.graphics.beginFill(0xFF88CC); sp.graphics.drawCircle(0, 0, 50);
[Code].....
however, I realize even tho im looping that addChild method, its still adding sp, so do I add a new naming convention in the loop, or should I be adding these instances to another display object.... this seems like such a simple thing to do yet I cant figure it out, I also want to randomize the x and y, but this first seems to be the issue I need to address.
I need to create curved Arabic text which can be change at runtime by input from Text Field. Currently I am using Text2Curve AS3 component. It works fine with Latin symbols, but I have several problems with it when it come to Arabic text: First problem is that Arabic letters comes in four different forms: end, middle, beginning and isolated. But Text2Curve AS3 component shows them the same.Second problem is that Arabic text shouldn't have any gaps between letters. But in component you can only set one letter spacing for all symbols. So some of the symbols overlap, while other have gaps between them.Third problem is that Arabic text is written from right to left, but Text2Curve AS3 component only supports left to right. (I solved it partially by reversing input string)If someone have had similar problem, or know better component/library (paid or free), or can event create one please let me know. Also I am working with Adobe Flash Professional CS 5.5 and I don't speak Arabic. So it is quite hard for me to check if Arabic text is good or not.
Basically I want the user to be able to create a line on runtime by first pressing mouse_down on the stage estabilisting the first xy points of the line and then move the cursor somewhere else to a different x, y co-ordinate where the user finishes the line by pressing the mouse_down button again. How to do this? I need it to be a straight line
I have a flash project that requires a swf file with over 300 textfields i.e a datasheet like in excel.i use actionscript 3 to dynamically add them at runtime.However I have a function calculate() that references them at compile time.So i think the problem is the caluclate() cannot find the textfields because they are still not added to the stage.How can i create them dynamically and after that add a function caluclate that will surely find the textfields?
Here is a code example of my work:
//add 50 textInput components for (var intr:Number=1; intr<=50; intr++) { var intTextField:TextInput=new TextInput();

THE CODE ABOVE DOES NOT WORK ,I want to create 10 moveiclips each with unique name, which I can move around or maybe load things into later. At the moment the trace returns 'undefined' so the movieclips aren't even being created.
I have a movie clip 'sliderMc' which contains two other clips 'slider' and 'groove'. I've used actionscript to make the 'slider' clip move along the 'groove' and display the value of the at each point in a text field. The idea is to have a slider object that i can use multiple times. I want a situation whereby I can create instances of 'sliderMc' so that I'll be able to move the slider on the individual clips and have each slider update different variables which would then be sent to an XML file or php. Im able tp talk back and forth between php and xml with no problem; The issue I'm facing is that after creating multiple instances of 'sliderMc', I'm not able to give the 'slider' and 'groove' movie clips different instance names without changing the instance names of all other 'slider' and 'groove' instances of 'sliderMc'. Which in turn makes it difficult to distinguish between the different sliders in actionscript.
I create X instances of a class (called SM) depending on a varibale I have (called here howmany), but later on as I want to check their states with a while, I need to have diferent instances names (sm1,sm2,sm3...).[code]
hmm how do I describe what I'm trying to do.. well here it is: In my flash library I have a series of movieclip with names like clip00, clip01, clip02 they are set to export for actionscript as the same name.
Now in my as file I'm importing a xml file that has the names of the clips which to place on the stage. Now if it were just a regular case I would do
[Code]...
I hope I am somewhat clear, please let me know if I can explain further. My project is really complex and I tried simplify it here. Please help or suggest alternative method.
why this sort of, but doesn't work?I'm just creating a group of buttons using imported pictures without having anything in the library.Here's the code I'm using:
[AS]clipArray = []; posArray = []; for (var k = 0; k<3; k++) {
So I know that if I want to create an instance of a movie clip called part01Roads from the library I do this:
Code: var part01Roads_mc:part01Roads = new part01Roads(); addChild(part01Roads_mc); part01Roads_mc.x = -22379; part01Roads_mc.y = 317;
Well I want to take this one step further if it is at all possible. Lets say I have 100 different movie clips labeled in a sequence: part01Roads, part02Roads, part03Roads ..... part100Roads. Instead of rewriting the above code 100 times, can I make a loop to do this?
I've done some basic flash for my college course and i'm moving onto advanced flash and Actionscript. For this, i'm trying to build a "construction game".
What I have is objects on the right side, and I want to be able to drag out copies of those objects onto the left and have the size and rotation of each object adjustable...
So say click and drag on a circle, it puts a copy of the circle where I place it on the left. I can then drag that circle around, scale it or rotate it, or if I decide I don't want it at all, drag it onto a recycle bin icon and have it removed.
I'd like to be able to make as many copies of that circle as allowed (so maybe a limit of 10?), and have each one adjustable when you "select" it...
Is this correct? I am gettign this errorTypeError: Error #1007: Instantiation attempted on a non-constructor.I am trying to created a new instance of a movieclip on stage based on the number from elderCount.
//elderCount is a var:Number var elderMan:Array = new Array(new starMovie()); var Star:starMovie = new elderMan[elderCount](stage);
I thought would be coded like this: var sp:Sprite = new Sprite(); sp.graphics.beginFill(0xFF88CC); sp.graphics.drawCircle(0, 0, 50);
