Actionscript 3 :: Explicitly Typing Variables Compiler To Instance Of A Builtin Type Doesn't Have A Property?
May 11, 2010
I narrowed the causes of an AS3 compiler error 1119 down to code that looks similar to this:
var test_inst:Number = 2.953;
trace(test_inst);
trace(test_inst.constructor);
I get the error "1119: Access of possibly undefined property constructor through a reference with static type Number." Now if I omit the variable's type, I don't get that error:
[Code]...
So what's the deal? I like explicitly typing variables, so is there any way to solve this error other than not providing the variable's type?
This is more of a rant than a question; but I am curious to know if anyone has some insight for me. The application I am working on deals with a C# .NET backend; communication is achieved via a socket over which we push AMF objects. The AMF object class definitions are generated by the server side team and I just have to use registerClassAlias on the flash side to link them up - pretty standard; the only difference being that as they come from a C# background they prefer to use UpperCammelCasing instead of lowerCamelCasing for property names.
Today I got a bunch of updated AMF objects which I dropped into the project; but I noticed that after updating my project would no longer compile [code]...
ReferenceError: Error #1069: Property . not found on builtin.as$0.MethodClosure and there is no default value. var srt:String = "2010.11.12 19:15"; var _split:Array = str.split(" "); var _date:String = _split[0];
[code]....
I just need to create a Date object from this string, like new Date(dateArr[0], dateArr[1]-1, dateArr[2], timeArr[0], timeArr[1]);
I'm coding an AS3 web app which needs to access the webcam. The webcam code works fine apart from my initial attempt to detect whether a webcam is plugged into the pc. I'm trying to use Camera.isSupported as specified in the Adobe docs but I get a compiler error telling me 1119: Access of possibly undefined property isSupported through a reference with static type Class. BriefingScreen.as /ADAPT_PSA/src line 147 Flex Problem I can get around this by compiling without strict checking but this seems a little clumsy...
Lately I changed Flash CS3 for CS4. In older version classes written by me worked fine. However, in CS4 I have serious problem with them. Compiler states that part of my functions and vars are undefined, which is not true. I tried everything - changing name of class, functions, moving class file to different directory, removing package. I even counted { to check if they have pairs. I'm really out of options what can cause those errors.
Here are error given by compiler:
1120: Access of undefined property mnChangeMan. 1120: Access of undefined property ChangeManSliders. 1120: Access of undefined property ChangeManInput.
working on an actionscript project to try and make an interactive drag and drop document. Currently everything has been working fine until I recieved this error after adding in another object to drag and drop. I've only added in one additional one so far, making the total of object in my script as two. I'm not sure why this error is coming up or what it means. Please let me know if the error means that my script only applies to one specific object or if I wrote it correctly to address all objects I place in my script
I have a very simple practice program for Flex 4 ( Gumbo ).

Why does it think that cPicker is static? Or that cPicker.hexValue is undefined? Also it seems that even after importing the ColorPicker library in the code using the import keyword, I somehow have to import it on the commandline for building as well. Is that correct?

Im trying to create an actionscript file that would take an XML output from a PHP script for the flash game that my friend is working on, but im always having the 1120 error. Here are the details
Compiler Errors: 1120: Access of undefined property fileLoader. fileLoader.load(file);1120: Access of undefined property file. fileLoader.load(file); 1120: Access of undefined property fileLoader. fileLoader.addEventListener(Event.COMPLETE, onLoaded);
I have couple of questions about AS3 variables handling by AVM/compiler/scope .1. This code in Flash will throw an error:
[Code]...
but it won`t throw an error in Flex (only warning in Editor). Why?.2. How Flash sees variables in loops? Apparently this:
[Code]....
isn`t equal to just: var mc:MovieClip=new MovieClip(); var mc:MovieClip=new MovieClip(); because it will throw an error again as earlier in Flash, but in Flex in function not? Is Flash changing somehow my loop before compilation?
.3. Where in a class in equivalent to timeline in Flash - where in class I would put code which I put normally on timeline (I assume it is not constructor because of what I have written earlier, or maybe it`s a matter of Flash/Flex compiler)?
I created my own FLV player skin and then wanted to know how to pass variables to flash via HTML so I could make my progressive download FLV player dynamic. I found a helpful tutorial on passing variables and just tried this tutorial out. I am using Flash CS3 and I am fairly new to Flash.When I get to the stage in the tutorial below of publishing to HTML I get the following Actionscript 3 compiler error.
Error message: 1120: Access of undefined property video.
1119: Access of possibly undefined property contentPath through a reference with static type fl.video:FLVPlayback.
Actionscript code: stop(); var passed:String = video; player.contentPath= video; [code]....
I am following a code example in a book and have the final fla and as files, so I know the project works when fully coded.In the book, it tells me I can test the movie to make sure that it is working so far. When I do that, I get the error 1120: Access of undefined property.
The "property" is a component instance. If I take the example completed code and remove everything up to the point I am at, I receive the same errors, so I know it's not a spelling/syntax mistake.I have a feeling it is the Compiler in Strict Mode. But, when I change it to Standard Mode, then I get error 5001: The name of package 'com.foundastionAS3.ch12' does not reflect the location of this file. etc.
note:: attached is a file of the compiler when it gives me multiple 1120s.
I am wrapping my brain around OOP in AS2. I am making two posts on two different subjects. My question here is: when should I use local instance variables, and when should I attach new properties to the instance object? (Feel free to correct my terminology.) Let's say I have a class for a scrolling background, which scrolls when I mouse over its edge. I want to put these values somewhere:
1) How wide is the border in which a mouseOver makes it scroll? This is basically a semi-constant I set it up once and keep it the same, unless the user changes it in an options menu to make the border wider or narrower. Call this scrollBorderWidth.
2) How fast is the background scrolling now? I want to track this so I can smoothly change the scroll speed over several frames. This is often changed. Call this scrollSpeed.
It seems I have two ways I can store and access these values and darned if I know which is better practice. METHOD A: Make them local variables in the class, so the scrolling background instance has them as local vars. I set them up thusly:
I have a list of strings that I add to an array, then attempt to set those values in a for-loop using data that I read in. The array gets updated, but the values the array contains do not. I also have an array of buttons that I update this same way that works great, but strings don't seem to work the same way. I have tried moving the string array to give it full scope, and still nothing...
public class test extends Sprite { // Declare a list of strings protected var title0:String = undefined;
I've embedded a MovieClip symbol with the [Embed] syntax into my AS3 project, which I'm compiling with the Flex 3 SDK. That MovieClip has instances of other clips within it that are placed on stage with instance names. I can't just access them by instance name like I would if I were compiling with the Flash IDE. How can I reference them?
I would like to make a little app to test out the Accelerometer class. I was thinking of using a Loader to load the swf, and replacing the Accelerometer with my own copy. Is there any way to do this? If it's not possible, how could I do this with a custom client?
I have a variable named "type". And I want to instance an object with the name of the value of type. Here is an example: var myObjectName = "ball"; var object = new ball(); //Except I want to use the value of myObjectName. I believe this used to be easy with AS2 when using _global, but I'm not sure how to do it in AS3?
I'm having an issue with Movieclips inside my Swf resizing to the wrong dimensions. I'm currently tracing the width of the offending clip every half second, and I can see the value change to an incorrect size at some interval in the logged output. I really want to see what code is changing the width. My plan was to extend Movieclip, override the set width property, and dump a stack trace when the value set is too low. This isn't so simple however. Flash is complaining about undefined reference to UI components that are on the Movieclip fla. Is there a simple way to find out when/why this value changes? I cannot use a debugger.
edit: The reason I cannot just extend MovieClip is because I am getting my Movieclip object from Event.currentTarget.content after using a Loader. I cannot point my Test (extends MovieClip) object at this return value because it is illegal to do so.I have an app with lots of different windows. They all open to a size of around 750x570. One of these windows contains a FusionChart. when I load this, according to my trace, the background Swf I am using changes to a dimension of about 2712x1930. This doesn't make sense to me because it looks the same size as before and at those dimensions it wouldn't even come close to fitting on my screen.If I then close the window and open another, the new window is tiny, but says it has the same dimensions as the original windows (750x570).
It is almost as if the window is scaling to the huge 2712x1930 without showing a change in size, and then showing the next window (750x570) as a size relative to what the huge window would look like. If that makes sense...
I have a site I'm maintaining that consists of multiple pages that tween in their menus on a single monstrous AS2 timeline. I've broken the timeline into their own swfs that I want to now network with a swf loader and AS3 code. I've kept the timeline tween-ins, after stripping the AS2 code off all buttons. I put the AS3 code on the last frame of the timeline in an .as layer.So on the main page, on the last frame of the animation in an ActionScript layer, I put the following:
Code: var defaultSwf:URLRequest=new URLRequest("defaultHeadShot.swf"); var swfLoader:Loader=new Loader(); swfLoader.load(defaultSWF); addChild(swfLoader);
[code]....
I keep getting the Type 1009 error. I'm trying not to have to rebuild the graphics from the ground up, which it doesn't seem like I will have to do. I think it's probably got something to do with putting all the code at then end of these complex tweening timelines, and that a line of code that offers a scoping cue might be the answer, but I'm stumped.
is there any way, within a class definition, to access the instance name of the class?as in, say you have a class "playerObject", and you instantiate an instance of it like usualplayer:playerObject = new playerObject();is there an inbuilt property or variable i can access within the playerObject class code to return "player"?if, in the constructor, i trace(this) it returns [object Object], i tried things like this.name, this._name etc, of course they didnt work...
In Flash CS5 I'm getting 1195: Attempted access of inaccessible method testFunc through a reference with static type Doc. when compiling and can not understand the circumstances, which I have boiled down thoroughly.
MyDoc.as - My document class.
package { import flash.display.MovieClip; public class MyDoc extends MovieClip {

I can get an error-free compile if I take the seemingly unrelated TLF text box out of the equation, either by changing it to a classic text box, deleting it, or unlinking its containing MC from MyClass. I can also get rid of the error by removing myOtherFunc()'s definition or moving it below myFunc()'s, which I had to do a few times just to convince myself that it was true.
Update: I just confirmed the same behavior on a friend's version of CS5. He's using a Mac as opposed to my Windows setup, and he only has the CS5 version installed, whereas I have both CS5 and CS4.
