ActionScript 3.0 :: Cast A String Into A Variable?
Apr 5, 2011
i have a list of items that get returned from a database. the list is composed of strings. what i need to do is convert each item into a variable so that i can use each item as an array.
for instance, my array will look something like this: deviceArray = ["osx106", "osx107", "winxp", "win7"];
what i want to do is turn each item into its own array. in AS2 (iirc) we had an eval() method. that is no longer supported in AS3.
I have a variable in flash:[code]I then have a multidimensional array which has this variable name in it, but as a string.[code]What I need to do is be able to reference the string item in the array, but then cast it so that when I add a number to it the ACTUAL variable with the same name will be altered - anyone know how I can do this?For reasons I won't go into I can't pass it straight into the variable, it has to go through the multidimensional array item.
I want to have a loader function that passes the loaded data to the correct function. So I can do this:[code]Is there any way to type the second variable to avoid the clumsy switch routine, like so:Function (sendTo) ();
var prevSec:*; var currentSec:*; var lastPage:String = "Default/Index";
[Code]....
And it's not working ("canno't create property visible on String"). I understand that if finds the variable to be of String type.
What i need to do is based on the switch to set a certain movieclip to go visible false or true on frame 16. I need to know how to cast the String into MovieClip.
Does anyone know how to cast a string into a uint?[code]...
But i keep getting an error stating that there is a mismatch in variable types or i get a value of '65280' when I trace myUint.I understand that uint is a positive integer but i need to accept a string for the colour value and need to convert it to a string for use.
Now I want to set the current game. I do this by copying the array, like so:
var curArr:Array; var curExc:int = 1; curArr = ("oef" + curExc) as Array;
I can't convince flash to accept the string ("oef"+curExc) as an Array. How do I do this?
I have searched Stack Overflow extensively but I think I simply don't know the correct lingo for what I'm looking for. It's the only possible reason I can think of why I can't find the answer here because I'm sure someone must have already tried this.
I have 52 symbols in my library each with class names Symbol1, Symbol2, Symbol3, etc. I want to create an array of these classes which will be used to create a random particle effect. How do I cast the var cardNumbers so that the array looks like this[code]...
I need to add values in a string (they're strings because I get a date as timestamp from a database and then pluck it apart in Flash with substring). Flash doesn't do math with strings. So is there a way to cast the string into an integer value?
i'm trying to modify a image, which is casted from a String:[code]In the inactiveElements Array are a bunch of ImageIds (way_0, way_1,..) and i'm trying to set the alpha-value of each Image.[code]with the trace i got the right String of ImageId but the cast to Image fails.[code]
I'm using as3corelib to decode/encode JSON strings. In my little experiment I want to encode an object (UserInfo) to JSON string and decode it back to the object, however it seems to fail at the convertion point (the last line), why would that happen? how can I make it work?
The UserInfo class
public class UserInfo { public var levelProgress : int; }
just learning as3 for flex. i am trying to do this:
var someNumber:String = "10150125903517628"; //this is the actual number i noticed the issue with
var result:String = String(Number(someNumber) + 1);
I've tried different ways of putting the expression together and no matter what i seem to do the result is always equal to 10150125903517628 rather than 10150125903517629.
We're making a simple input text comparisons vs. some constant floating point numbers (e.g. 4.35). Using Actionscript 2 to Flash 9 export. Getting totally contradictory traces on two different computers compiling identical code...Here's some simple code we're using to figure out what's going on.
Also, what behavior do any PC users have? I'm expecting the latter since they're generally intel chipsets too?Note: once i compile the code on my PPC mac, intel macs that run the SWF (but don't recompile the FLA) do return the correct booleans that match the PPC output.
Is it possible to cast a variable as a type dynamically, where the type would be a variable of type Class? Consider the following (invalid):
var myClass:Class = MyClass; var myInstance:myClass = new myClass();
For context: I'm working in Flex (4) to create a modal manager that will control various aspects of creating modals (via PopUpManager) and I'd like to keep it as minimal as possible. Components would be passed through the same functions, and rather than allowing any type of variable to be cast, eg:
I have a String variable in my flex (flash builder 4) application containing CSV data. I need to allow the user to download this data to a local file. For example, giving them a "csv" button to click and it might present them with a save file dialog (and I would be sending the contents of my string variable).Is this possible / how ?I am using the ResuableFX component for the datagrid to csv. This the code I ended up with that works to save the string to a text file for the user (in a web browser):
var dg2CSV:DataGrid2CSV = new DataGrid2CSV(); dg2CSV.includeHeader=true; dg2CSV.target=adgEncounters;
Trying to replace a portion of a string with a "-" if it matches a string variable in AS3.
var re:RegExp = new RegExp(imageArray[j][1],"gi"); trace(imageArray[jTemp][2].replace(re,"-"));
imageArray[jTemp][2] is a string imageArray[j][1] is a string as well I'm not getting the result I expect. I would like trace above to return 'permanentContainer-' Here are the traces for the above variables
how you would target a function's local variable through a concatenated variable string.For example:
var txt = "Hello World"; function testing(msg) { var test1 = msg;[code].........
I'd expect the trace to be "Hello World" but rather is given "undefined". So if variables created outside functions are created on the main timeline, where are local function variables created and how would you access them?
i'm getting a value from a class that gives me e.g "icon1" as data. i want to use this within a function to control the visibility of an item nested in a movieclip on the stage. the nested movie has the same name as the data being sent.
// here's what i want it to do: mymenu.icon1.visible = true; // but i cant append the 2 together as flash will see it as a string not read it as path.
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?).
This is sort of difficult to explain but I'll do my best. I've got 6 score variables that go up over time.
[Code]...
Each corresponds to a different color of "Monster" class I reated. "GreenMonster", "BlueMonster", etc. are all custom classes. Each class has a string property called "MonsterColor". So "Blue1.MonsterColor = "Blue".
To save lines of code, and learn, I'm trying to use a local string variable to take the place of whichever of these 6 int variables I need. So inside a for loop, I've created a variable called "colorscore".
I would like to dinamically create array variables, depending on a XML file. The problem I have is that I don't know how to create them dinamically using a name I have constructed into a string variable. What I would like is something like this:
var strVarName; ... strVarName = "Var" + i; var strVarName = new Array(); ...
So I would have n arrays called Var1, Var2, ... Varn.
I am trying to go about a "smarter" way of setting up multi paged full flash sites. This has got to be something very simple that i can't seem to put my finger on.
I'm trying to create a variable called 'currentScen' that i can declare off the start and change depending on what page the viewer goes to in the site.
I could put a bunch of 'if' statements saying that 'if the current page is this page then do this, if it's this page do this' etc. for each individual page but i thought there must be an easier way.
I am trying to get the following to work:
Code:
// declaring what the starting page is var currentScen:String = "welcomeMovie"; //function fading in called page with animation used on the 'over' frame label function animateOn(page:String) {
What is the best way to listen for and trigger a function when a string stored in a variable changes? I have a variable named source which is a string. When its value changes I need to run a function newVideo. What's the most efficient way to detect the string has changed?
having an issue with a variable set. It is set as a string to default "no" on the very first frame of my movie, as follows:
var myaccess:String; myaccess="no";
Within my movie, there is an object. When this object is pressed, it is to change the _root.myaccess="yes"; I am tracing the variable within the movie clip and it shows me: I do not understand why it is changing my string definitition from "no" to false. Because of this, my variable does not seem to change to "yes' on object (button) pressed.
