I know that I can get info about constants, methods, etc of a class by using flash.utils.describeType. But I want to know if I can retrieve the asdoc comments of a class member.
I suspect, documentation is removed when classes are compiled into SWF so it might be impossible to get comments during run-time.
I recently found a method (ByteArray.clear()) that FlexBuilder complains is possibly undefined; however, the method is in fact documented in the Flex LiveDocs. It must have been added in a later version of the SDK than I have installed. I'm not asking about this particular method, but I'm giving it as an example of the documentation issue that I'm trying to resolve. My questions are:
How can I determine what version of the SDK or Flash player that a method or property was added in? How can I tell which versions of the SDK are supported on which Flash player versions?
I want to be able to determine from the documentation, instead of compiler or runtime errors, what SDK and Flash player versions are needed to support newly added methods.
With Java I look for the @since javadoc tag when I need to know this, but I can't find an equivalent feature in the Flex docs.
I have this MenuBar control in Flex 3. How can I programmatically change the toggled property to false?
<mx:MenuBar labelField="@label" itemClick="itemClickHandler(event);" left="0" right="0" top="0" id="menuBar">
<mx:XMLList><menuitem label="File" data="top">
<menuitem label="New" data="file-new"/></menuitem>
<menuitem label="View" >
<menuitem label="Grid" type="check" toggled="true" data="view-grid"/>
</menuitem></mx:XMLList></mx:MenuBar>
In Flex I've got a component, which is based on a Canvas.It looks like this (I removed the <mx:Script> for better reading):
<mx:Canvas verticalScrollPolicy="off" showEffect="showFX" hideEffect="hideFX" horizontalScrollPolicy="off" creationComplete="doComplete()" xmlns:mx="http://www.adobe.com/2006/mxml" width="63" height="63">[code]....
If I set customComponent.Visible to false, the component gets hidden (as expected). But doesn't trigger the hideFX at all. Am I doing something wrong? Or isn't this the correct way to use hideEffect and showEffect?
I want to create an array of strings in a text class that I can access with the main document class. Then I'll be able to populate a text field with items in the array. The purpose of this is to avoid having massive lines of text in my main document... but I can't even get my test to work. The compiler is telling me that the array (txt1) is undefined. First here's my code for the array:
//text array class:format5000
package {
import flash.display.MovieClip;
import flash.text.*;

For example, if an application uses class, method, or property which is supported only by Flash Player10.When you run the application on Flash Player9, what will happen? Flash Player will be crashed? Or Flash Player will show you a message screen to upgrade your Flash Player? Or the application will normally run and will ignore the part which uses the unsupported class, method, or property? Or the application will cause a runtime error when the unsupported class, method, or property are called?
View 2 RepliesIn Visual Studio, when we write some code, there are code hints, for property,custom method of some class that we create.There are code hints on Flash CS4, but it seems that it didn't show code hints for custom method or property on some class . Is there any way to make Flash CS4 show code hints for custom method, property and namespace that we created ?
View 2 RepliesI'm having some trouble implementing a "virtual" camera for use in game development with Flash CS4 ActionScript 3.0.Basically, what I'm trying to accomplish is to have a camera that moves about the main stage so that my character can traverse the level which is much larger in size than the stage itself.I've been using Sham Bhangal's virtual camera script, and when I implemented it by sticking the code into the first frame of a movie clip, it worked great!
From there, I moved the code into a document class that i could instantiate and then drop onto the stage as a child.Finally, I wanted to have a main "builder" document class that would be added to the main stage as a child, and within THIS class I wanted an instance of the virtual camera. This is where I hit some obstacles.how to properly instantiate the virtual camera within the builder class which is then added to the main stage. I have a Stage reference that is being passed to the main builder, but I don't know where to go from here. To what do I add the virtual camera to as a child? To the Stage reference in the main builder class? To the main builder class itself?The main issue is that when I export my movie with the virtual camera added as a child to the Stage reference within the main builder class, it complains that I'm not allowed to access certain values.
Code: Error: Error #2071: The Stage class does not implement this property or method.
at Error$/throwError()
at flash.display::Stage/set x()
This happens when I try to access parent.x from within the virtual camera class. I assume this fails because "parent" from this perspective is the main builder class, but using the Stage reference produces this same error.I am, of course, willing to provide more detail if something I've written is confusing, and I will gladly provide a detailed fix for those seeking to use a similar solution in the future.
I have a simple quesiton about class, method and functions inside a method and class properties. I created a new class form my custom component.. But upon developing it I found out that you can not access a property inside the function which is also inside a method..
Example
Code:
class myClass{
private var myProperty:Number = 1; //default is 1
//constructor
public function myClass(){
}//Method
[Code] .....
What I want to do is to access the property inside the method.. I also have a work-around still i cannot point a certain variable to a property of my class inside the method's function..
So I've been trying to move the stage's X and Y position and keep on getting this error:
Code:
Error: Error #2071: The Stage class does not implement this property or method.
at Error$/throwError()
at flash.display::Stage/set y()
at Main/scroll()
I am using a document class, here it is:
Code:
package
{
import flash.display.MovieClip;
import flash.events.Event;
import flash.events.MouseEvent;

As for why I'm trying to move the stage, I have a movieclip which moves according to keyboard input and i want the stage/Background to always center on him.
Error: Access of undefined method getStatus through reference with a static type Class.
Here's what's happening in the code. I'm trying to create a User class that is instantiated at the start of my app. I want the User class to have properties like mainStatus, with helper methods like setStatus etc. Pretty simple.
so on my HardDisk I have my flash_working folder with all my flash projects. I created my class file/package under the directory com.mypackage
[Code]....
That's all the code I have.
If I try to access the public var mainStatus through user.mainStatus that gives a similar error saying:
Error: Access of undefined property mainStatus through reference with a static type Class.
Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
I've been working on a framework in AS3 that I want to release, but first I obviously need to prepare some documentation for it.I've noticed that quite a few sites have the exact same layout, functionality etc as Adobe Livedocs, which has let me to believe that there's something open source out there for creating online documentation.
Ideally the system would be specifically suited for documentation in ActionScript 3. I don't have a requirement in terms of the documentation being automatically generated either - if there's something out there that looks/works nice I'm happy to manually create the documentation (provided it comes with tools for easily adding classes, arguments, etc).
If I have a .mxml file that has a method in it and a public property, can I have the method execute whenever the property changes.

<mx:Script>

In another .mxml file I have added this .mxml file like so:
<viewComponents:MyViewComponent myProperty="{myVariable}" />

How do you add sample xml to asdoc function/class comments in Flex? They can obviously be added, but they wont show in the hover asdoc comments in Flash Builder 4. [code]...
View 1 RepliesI have a canvas based component, so when I check the asdoc comments, they have inherited comments of Canvas. can we remove that inherited comments, and add our own AsDoc comments..
View 1 RepliesI'm in the process of making a game (a shmup) and I've started to question the accuracy of the timers in ActionScript. Sure, they're accurate enough when you want to time things on the order of a few seconds or deciseconds, but it seems to perform pretty poorly when you get to finer ranges. This makes it pretty tough to do things like have a spaceship firing a hundred lasers per second.
In the following sample, I tested how long (on average) the intervals were between 1000 timer ticks intended for 30ms. Time and time again, the results are ~35-36ms. Decreasing the time, I found the floor on the timer delay to be ~16-17ms. This gives me a max fps of ~60, which is great visually but also means I can't possibly fire more than 60 lasers per second :-(. I ran this test a few times at 100 and 1000 loops, but for both the 30ms test and the 1ms test the results didn't change. I print to a textField at the end because using trace() and launching the swf in debug mode seems to negatively affect the test. So what I'm wondering is:
Is this test a decent measure of the Timer class's performance, or are my results questionable? Will these results change dramatically on other machines? I understand this is dependent on the getTimer() method's accuracy, but the discussions I find on this topic usually center around getTimer()'s accuracy on larger intervals.

FlashBuilder's undocumented mm.cfg file has a lot of cool options as shown here and elsewhere. But what about commentsout there verify if comments are supported in FlashBuilder's mm.cfg file?If so what are the rules? For example:REM .bat style comment; .ini style comment# shell style commentines?
View 1 RepliesOver the past three weeks, I have lost at least 120 man hours because of some lesser known functionality in ActionScript 3. One of the problems was that, with Internet Explorer, if there are too many messages sent through LocalConnections, it will slow the messages sent through, but in the standalone player and in Firefox, this threshold is significantly higher. Another was that the static values of a class are instantiated even if the member itself is not being used:[code]Since FooClass had a static reference to a Singleton, that Singleton was instantiated so when I loaded a Module which used that Singleton, it would bind to values in an unpredictable way.Additional cases where things behave in an unexpected way:
So here's the question (and I'm sorry for omitting this in the original post), is there any consolidated documentation for this type of behavior anywhere? Is there any (even non-Adobe) documentation on these issues (websites, forums, books, ANYTHING)? I know that these things are definitely easy enough TO document, but has anyone done so?
If all I have is an instance of an object, can I call a static method of its class? For fun, let's say I don't know what the name of the class is, only the name of the static method.
