Actionscript 3 :: Determine If Value Is Class Constant?
Mar 10, 2011
i'd like to throw an argument error if a particular function doesn't work without a passed value that also happens to be a public constant of the class containing the function.is there anyway to determine if a class owns a public constant instead of having to iterate thru all of them? something like this:
public static const HALIFAX:String = "halifax";
public static const MONTREAL:String = "montreal";
public static const TORONTO:String = "toronto";[code]....
currently, for this functionality i have to write the city setter function like this:
public function set city(value:String):void
{
if (value != HALIFAX && value != MONTREAL && value != TORONTO)[code].....

I have a piece of art I made on the timeline that I want to turn into a button, so I comverted it to a symbol and exported it to actionscript with a linkage class, but when I compile it and run it I get the error, 1046 type was not found or was not a compile time constant: playButton22.[code]

Is there a way to declare and instantiate an array using constants as indexes? I want to do something like:
public var arr:Array = new Array([ CONSTANT_A : "helloWorld", CONSTANT_B : "helloGoodbye" ]);
In php one could do:
$arr = array(CONSTANT_A => "foo", CONSTANT_B => "bar");

since the MXMLC compiler doesn't support mixed access modifiers for setters/getters, i would like to know whether a public setter function is being called from inside or outside of the setter's class. this approach should allow me to maintain a public property but with more security, something like public/private hybrid access. is it possible to use arguments' callee property, or perhaps something else, to determine whether the setter was set internally from the setter's class or if it was set externally?

I am working on a Flex Front End at the moment, and have been using the Parsley framework for passing messages/events around.
I was wondering if there is a simple way for a function (in this case, an event's constructor) to obtain a reference to the object which called it?
This is to ensure that a certain event that I am defining can only be dispatched by one specified class. My thinking is to check the caller of the constructor somehow, and throw an error if it is not of the correct type.

For this example, I will use 2 classes, Entity and CSpawner. CSpawner is a children of Entity.I want to perform the following condition:if((new CSpawner()) is Entity)It works just like intended.But I want to do this test, without creating a new CSpawner object, something like this:if(CSpawner is Entity)But it doesn't work, because CSpawner is a Class.How do I perform that kind of conditional without creating a new CSpawner object?

In Actionscript 3, if I'm given a Class object, is there any way to determine if that class extends from another given class? I don't want to instantiate the class to check it with the is keyword, though.

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'm puzzled I can't find a constant for the minimum value of int in actionscript.
There's Number.MIN_VALUE, but, as the name implies, that's for Number, not for int.

I am trying to set a constant hue value for entire image with using ColorMatrix. My goal is to make entire image look with same color without loosing brightness of any area. I found a way to shift the hue values of an image by using ColorMatrix but i couldn't find any way to set same hue value for all pixels. I can do it with iterating every pixel of image but this approach is too slow. I am not sure if it is possible to do it with ColorMatrix and i am open to possible solutions other than ColorMatrix approach.I can do this with iterating pixels but not with ColorMatrix.I am trying to do this on Android but i believe the question is not directly related to the android since ColorMatrix approach is common on other platforms like Flash, C# etc.

On PC games I've written the game logic and render are seperate calls.This allowed me to time how long the render is taking and therefore only draw when there is time. The result of this is the game runs at the same speed on any PC but the graphics are smoother on a higher spec PC because the render is done more frequently.How do you achieve the same in AS3? - how can I time the render? - when is the actual render done?. Do I simply time the exit from my base class and also the entrance into it, is the difference simply my 'render time' - of course flash may do other things during the exit/enter of my function.I'l looking to maintain a frame rate of 50fps on the logic with a render 'when can'

I have an object on the field, 'ball', and three buttons: 'left', 'right', 'stop'. What I want is that when Left is pressed, ball starts travelling to the left at a speed of 7. Same with RIGHT, and STOP stops the movement. What I don't want is that the ball moves only when you hold down the LEFT or RIGHT buttons, which is all that I can achieve so far.

what I am doing is an animated flash version of a rockola bubbler jukebox. Problem is, the bubbles. I have tried just doing something simple with movie clips and motion paths, just on the animator side / no actionscript code. I wouldnt mind using AS code, but I am pretty novice at it ( very novice actually ) and am having troubles.I cannot get a constant stream of bubbles though and it looks bad.

I'm trying to get a movieclip to constantly rotate either left or right. At first I set this._rotation=-1 Then I was thinking of using
if (this._rotation==1) {
this._rotation = -1;
But this only makes the object rotate 1 degree and then stop. How do I make it constantly rotate?

I do not understand how coordinate systems and movieclips work. When I add a movieclip to the stage and set it's position I expect it to appear there. If I have a movieclip with it's center in the middle, and I add it at 0,0 to my stage I expect it to appear in themiddle.nstead when I add a movieclip to my stage the stage gets bigger... even though the movieclip I added doesn't extend past any bounds of the stage. When I try to make an object tween from one position to another it works half the time but as i add and remove children it begins to fail because the coordinate system is constantly changing.
How can I enforce a static coordinate system on my stage? Or how can I be sure that when I make a tween to move a movieclip from point A to point B that point B won't move around in the time that it's animating?t seems with flash that every time I encounter a problem I am boggled by how little sense it makes and how hard it is to find any information about it. I must be doing something terribly wrong.

maybe this is something small I'm overlooking, but I can't figure out how to pull this offI have an XML file that keeps data on my tilesheets. Currently it keeps info on the width and height of the tiles (works fine), but I also want to tell my program what part of ananimation it belongs to. I have a class set up that keeps some constants on the state of the object, that will decide it's animation. For example, if the state equals"PlatformState.WALKING", I alternate between tiles 1, 2 and 3, if the state is"PlatformState.FALLING", It alternates between 4 and 5.The static constant PlatformState.WALKING is a uint with value 0, FALLING has value 1, etc. But I don't want to put the rough values in the XML, but the constant names.

I am trying to get an object to track my mouse on press and i am using a tween. However, the nature of the tween is such that the time taken for the object would move would always be constant despite the distance.
I would like to make the object travel at a constant speed regardless of the distance. Is it correct for me to use a tween? If not what should I be using?The code for my tween is as follows.
map_mc.tracker_mc._x = map_mc._xmouse;map_mc.tracker_mc._y = map_mc._ymouse;startx = map_mc.crosshair_mc._x;endx = map_mc.tracker_mc._x;starty = map_mc.crosshair_mc._y;endy = map_mc.tracker_mc._y;
trackTweenx = new Tween(map_mc.crosshair_mc, "_x", Regular.easeIn, startx, endx, spd, true);trackTweeny = new Tween(map_mc.crosshair_mc, "_y", Regular.easeIn, starty, endy, spd, true);
map_mc.tracker_mc is the mouse cursor that would appear when onPress while the map_mc.crosshair_mc is the object that would track my cursor's movements.

I'm a CS4 developer, working in Flash, Dreamweaver, Premiere Pro, Photoshop, etc. I love Adobe products, but I am getting pretty weary of Flash Player updates coming every other day, sometimes every day. I work on several computers, both at work and at home, so the inconvenience of having to stop and go through the update process is multiplied. I know it's not usually a time-consuming process, but still, why so frequent?
It might not be so bad if not for all the other self-updating applications on my systems, not the least of which are the various Windows updates. It's just a little obnoxious.
