ActionScript 2.0 :: Access Symbols Using Loop Index In Instance Name?
Nov 30, 2010
Upon the stage of my flash movie, I have several symbols (movie clips) which I need to address dynamically using a loop. The symbols that I want to address all have instance names beginning with the string "lamp_", they then each have a different number concatenated on the end to distinguish between them (e.g. lamp_1, lamp_2, lamp_3.....).
The following noobish effort I have devised is totally useless, and I am hoping someone can show me how I might get this working[code]...
I am trying to get the index of an object which is an instance of a class. I need to get the index from within the class.So I have an instance of a class. When its clicked I need to get the index. I dont really know how to write this. I tried a few things like:[code]
I'm trying to keep track of several movie clips with an array, but I'm running into some issues. I'm making a shooter game that requires hitTesting a list of projectiles and removing the projectiles from the list when they leave the screen or hit stuff. I've got the projectiles being added to the stage with this:
[Code]...
At first that appeared to work fine, but the bullets aren't always removed in the order they were created, so when I remove one from the array in this manner, it shifts the index numbers for all the ones that came after it back one, thus making their "num" variable no longer correspond to their index number; so when they try to splice themselves, they end up splicing the wrong ones. (Like, if I removed [3], the bullet that was in [4] is now in [3], but it doesn't know that, so it tries to splice [4], which now refers to whatever was in [5], and so on.) What's the correct way to handle this kind of situation? I feel like I must be missing something obvious, but I haven't been able to figure out a solution.
Is there a way to access all exported symbols in a *.swf file?
I mean all the symbols that are marked Export to Actionscript in the Library of Flash IDE. That way I could use getDefinition() class without having to know the name of the symbol beforehand.
This is for an internal tool made in AS3 that will work along a framework, which needs to perform some operations on every symbol of a *.swf file. So performance isn't required, and a hackish solution (accessing ByteArray of the swf or something like that) is valid.
I ended up using as3swf to parse the ByteCode of the *.swf file and read the class.
Here's a simple function I made that returns an array containing the symbol names, ready to be used with getDefinition(). You must pass in a ByeArray of the *.swf file.
private function getSymbolList(bytes:ByteArray):Array { var swf:SWF = new SWF(bytes); var ret:Array = [];
Is it possible to return the index of the first instance of a specified value within an array? Similar to:
Code: var my_string = "string"; var index = my_string.indexOf("g");
/*Outputs:
1 */
Basically, I have two arrays, each with 10 values (in slots 0-9 of the arrays). So I need to see if an array has a specified value in it, but then I have to see if the other array has a certain value in it, in the same spot as the first instance of what I search for in the first array.
I have a ComboBox, with it prepopulated with the States.When I have a variable that says it should be pre-selected to for example CA, how do I do that, without haveing to figure out the index number for every single state?
Let's say I have Class Holder linked to a MovieClip holder_mc. holder_mc has a child held_mc that has a Graphic Symbol pic_gr. pic_gr has multiple frames.
From the Class file of Holder, how would I change the frame of pic_gr? I also didn't see a way to name the instance of pic_gr, is that right?
just like facebook game, I see that even I am playing facebook social game, it still have some downloading when I click on an item for the first time, or just by doing something new. Is that people can divide flash into many parts and connect them when they need?
I have a package that extends my sound class that I want to also control the alpha of an existing symbol on my stage. I have read that this would be ideally done through some sort of event listener but I can't find a way to do it. Basically, my package generates a wavelength that I want to control the alpha of an existing library symbol. I have gotten examples to work the way I wish but can't seem to get my package to access the main .swf's library.
Here's the code:
package {import flash.events.SampleDataEvent; import flash.media.Sound; /** * A dynamically generated binaural beat carrier wave Sound with frequency easing. */
Consider an array with x number of elements (of type Object) where some of the elements might be undefined.I use a for-each loop to access all the elements of the array that is not undefined (since it simply skips the undefined elements).But I also want the index of that particular element.The only option I can see is to use indexOf(). But it feels a bit like looking for water on the other side of the river so to speak.
When looping through long arrays each frame, is there a change indexOf() might slow it down? or does the for-each loop somehow know what index it's dealing with?

I'd like to use a for-each loop to access all the elements of the array that is not undefined (since it simply skips the undefined elements). But, I also want the index of that particular element.
So I have two options: 1) Use array.indexOf(element). 2) Use traditional for loop, thus getting the index out of the iterator.
I'd rather not use option 2 since it contradicts the whole idea of not having to deal with undefined elements.
I search the stage for the level I created and put the floor pieces into an array. I'm trying to test the properties I created for each piece by tracing to output when the hero sprite is within the floor pieces sides. This works fine when I specify the array index to do this for, but does not work when I try to loop through every element of the array. I see no reason why this code should not work.
package { import flash.display.*; import flash.events.*; import flash.utils.getTimer; import flash.utils.Timer; public class MegaManTest extends MovieClip { private var hero:Object; [Code] .....
I am adding movieclips (myBall) to the stage by the click of a button. There is a base class applied to myBall which allows it (and its children) to be dragged and dropped. Within the base class on mouse down, along with startDrag, the movieclip is being brought to the top index. I would like to be able to refer to this movieclip in my document class. The point of doing this would be to apply a function to the last clicked movieclip (finding what movieclip was last clicked would happen by applying the function to the movieclip (myBall) with the highest index).[code]...
I have used the flash accessibility tab to add index numbers to 19 elements on my page.However, once I reach tab number 19 I cant get it to loop back to tab index number 1.
This adds five new instances of the Thing class through the main timeline. In the Actionscript code for the Thing class I want to be able to reference the index of the given instance for identification purposes.
I would like to edit a cell by the row and column indexes so essentially do the following:
advDataGrid[2][3] = "Dogs"
so that I am setting the data grid row 2 and column 3 to Dogs. I cannot for the life of me figure out how to do this!
Side note: I need this because I am trying to allow the user to copy a section of an excel file to a section of an AdvancedDataGrid like Google Docs does. I am using this idea to do it: [URL]
Basically, I have data organized by date in an XML file. I'm trying to make a website application that will allow the user to click on a date (in a text field) to see another textfield populate with all the data under that particular date. So far, all the information loads into the textboxes at the same time. How can I get it to only load information under a particular date when somebody clicks on that date?
Before I started this project, I was convinced I could do this by manipulating the [j] (see code below) in the myFunc2 function. Currently, it's set up to increment blank_mc._y by whatever value is returned by [j]. But for some reason this doesn't work. I feel that if I could atleas get this part to work - I could probably do the rest.
AS code:
Code: function loadXML(loaded) { if (loaded) { var nodes = this.firstChild;
I have to admit I pretty much ran away from Flash when AS2 came along and only used it for animation purposes over the last 5 years.So I'm having a major crash course in AS3 in Flash CS3 and I'm not enjoying it one bit. I'm getting maybe 10mins of finished work per hour as I try to figure out the limits and rules of AS3. Quite often it seems that AS3 simply can't do what I want it to. Anyway: Characterchecks.as is the main class and it loads a bunch of XML into four arrays. The file starts like this:[code]If I trace the value of, say, cc._Categories from the main FLA, it's empty. I'm guessing that the next line of AS in the main FLA doesn't wait for the previously called function to complete? (This may tie in to my next problem)My next step is that I want to display various things based on the data in the array. I have another class, Display.as which will hold all the functions to create the items on display. I thought it would be best for these to be a separate object. I wonder if I'm right?
So I declare an instance of Characterchecks in the main FLA and call it cc, and then run the functions to populate the arrays... Now I create an instance of Display and call it cd. How can I get functions in cd to see the values of the variables in cc? And if the main timeline can't tell that the functions aren't finished filling the arrays, how is cd supposed to know?I might be asking dumb questions, or maybe I'm doing things ***-backwards, I don't know. I'd appreciate any help, I really would. This whole thing has me at the end of my tether... being the most technically advanced person in my circle of co-workers and web design friends means I have no-one to explain why things need to be done a certain way or what the best way is.
I'd really like to be able to make Flash's array access syntax 'wrap' over the array's bounds.
Lengthy explanation -
var array:Array = ['a','b','c','d','e','f'];
To keep things simple, the first index is 0, and its value is the first letter, 'a'. To get that value, we'd do this -
array[0]; // returns 'a'
As long as the index you're using to access the array is between 0 and array.length (6 in our example,) everything works fine - but if you use an index outside of those bounds, you're shut down.
array[-3]; array[9]; // both return 'undefined'
Sometimes that's a good thing - sometimes you expect that to happen, and you're fine with it. Other times, you find yourself wishing (or at least I find myself wishing) that it'd behave a bit more like this -
array[-3]; array[9]; // both return 'd'
(e.g. a photo gallery that jumps back to the beginning when you click 'next' on the last photo)There's a little chunk of code I use over and over for this sort of thing, but it's always to alter the index before passing it into the array:
var index = -3; while(index < 0){index += array.length} array[index % array.length]; // returns 'd'
... and that's fine, but what I really want to do is extend the Array object itself so that it'll automatically 'wrap' index values that go out of bounds.TL;DR - Is index-wrapping possible by extending Flash AS3's Array object?
I used this tut to create a menu. [URL] And my question is; Can I make the slider to move after a movie clip symbols instead of button symbols? That way my menu would be animated.
I'm working through a book called Foundation Game Design with Flash, and I'm finding the Flash IDE confusing. I've been programming for several years, so working with AS3 directly is far easier than trying to understand symbols and nested symbols and the difference between graphics and movie clips and scoping issues and all that -- when tied into the IDE.
How many of you who are making games in AS3 also use the Flash IDE? Can anyone recommend a resource that is AS3 heavy and Flash IDE light? I don't care how much time I may or may not save by using things like the timeline, I just want to understand what I'm using.
I'm attempting to use CS4 (PC/Vista, if that matters) to create a SWF file that will basically act as a "library" of commonly used symbols. This SWF would be loaded at runtime by other SWFs, which could then use the symbols within it, including all art and code assets.
What I have is a lot of buttons (over 200), and I want to loop through them all. They're all instances of the same graphic symbol in the IDE, so there should be a way to loop through them all.
If I was doing this or something similar in JavaScript, I could do something like: document.getElementsByClassName('MyGraphicSymbol') and then I'd have an array of all the elements. So looking for something like this in AS3.
Is there a built-in function to loop through each instance of a class (like for each for an array) or must I put them in a container and loop through every child of that container?
I am trying to add a LOAD EXTERNAL MOVIE CLIP behaviour to a button sitting in a .FLA called SERVICESMENU. I want to load a .swf titled MULTIMEDIA.SWF into an instance of an empty symbol called PAGE LOADER on a different .FLA called MAIN.FLA.
The problem is when I am in the SERVICEMENU.FLA file, I cannot see the instances that I created in the MAIN.FLA when following the behaviours wizard so I cannot choose the PAGELOADER instance that was created in and resides in the MAIN.FLA file.
