Is there any way that I can reference a var or const as the default value for a function argument in actionscript 3. I can define default values like null, string, int. function a( b = null ) { blah... } But what I want to do is function a( b = function(){} ) { blah... } which it seems like there would be a way to do. Presuma...
I've seen it used a couple places: http://livedocs.adobe.com/flash/9.0/ActionScriptLangRefV3/ http://developer.yahoo.com/flash/astra-flash/classreference/ Is this just a coincidence or is it somewhere I can grab? I'd love to use it for a new project I'm working on. Thanks! ...
Make a new AS3 Document in Flash, paste in the following code and run it: var a:Number=0; trace(a) // 0 a+=0.3; trace(a) // 0.3 a+=0.3; trace(a) // 0.6 a+=0.3; trace(a) // 0.8999999999999999 a+=0.3; trace(a) // 1.2 a+=0.3; trace(a) // 1.5 a+=0.3; trace(a) // 1.8 a+=0.3; trace(a) // 2.1 a+=0.3; // ^ This is th...
Hi, If someone logs on to my application this user contains a dictionary with certain permissions. ex: module.view.workspace = true module.view.reporting = false ... Then we know to what parts of the application the user has access. What I want to know is how we can apply these permissions on the view. We are working in an AS...
Probably not much more to elaborate on here - I'm using a NumericStepper control and I want the user to use the buttons only to change the value in the NS, not by typing into the control - I couldn't find a property to disable the text - does it exist? If it doesn't, how would I subclass this thing to disable the text? ...
Im loading the xml in, and Im able to read the xml nodes into text fields in my flash. It is also loading the url, but the last one from the loop. Its not loading the one that I click on. I tried using event.target, but that is not working. Im pretty close to figuring it out, Im just not sure where to look. Any help would be greatly appr...
How can instantiated classes access the Document class? Even after I name the Document class using the Properties bar in Flash, attempting to access it from other classes usually fails, saying "attempting to access an undefined property... One solution is always casting the Document class to itself! eg. Main(Main).globalMethod(); Bu...
I have a dataprovider and a filterfunction for my array that's assigned to my dataprovider. How can I get a list of the properties that are in each row of the dataprovider (item.data) as it gets passed to the filterfunction? For instance, if my object contained: Object name email address Then I would want, in my filterfunction ...
Hi, I am a Java programmer and need to work on a Flex/ActionScript project right now. I got an example of using ITreeDataDesriptor from Flex 3 Cookbook, but there is one line of actionscript code that's hard for me to understand. I appreciate if someone could explain this a little further. public function getData(node:Object, model:Ob...
When I set a component to visible=false the component hides, but how do I get it to take no space (get the container it belongs to to resize??) <mx:HBox width="100%" height="100%"> ... </mx:HBox> <mx:HBox width="100%" id="boxAddComment" visible="false" > <mx:TextArea id="txtComment"/> <mx:Button label="Spara" click="addCommen...
Is it possible, using actionscript 3 to disable the right click menu? Any help greatly appreciated! ...
I'm using HTTPService with a POST operation to submit a Base64 encoded file (taken from bitmap data within the app) but I could really do with getting some idea of the progress of the POST operation (e.g. like the FileReference.upload()). I don't think this is possible, but it would be awesome if it is (via any means, I'm willing to cha...
I'm trying to get a dynamic movie clip from the timeline. I have a timeline of unknown length with a movie clip with instance name "blah" on one of the key frames (assumed 88 in this case). No matter what I do, I cannot get a reference to the said movie clip. Here's what I tried: trace(blah); // null trace(this.blah); // null trace(g...

My TileList has allowMultipleSelection on. I am using itemClick to call a function. I can use listEvent.currentTarget.selectedItem to determine what object was just clicked on if I am selecting, but when I ctrl + click to deselect an item, it automatically selects something else in the TileList, thus changing the selectedItem. It seems l...

I am using AS3 to create a tween affect between multiple images that have a drop shadow around them - it works great, except after 3+ tweens the drop shadow starts getting darker and darker - that makes sense, but not really want i want to happen. Ideally i would like to tween between 2 images, on the 3rd clear it out or something? I a...
Hi, I'm having trouble computing reflection angles for a ball hitting an oblique wall. I'm using an algorithm lifted from this tutorial. It looks like this (in Actionscript 3), with p1 being the current velocity vector and p2 the normal of the wall: private function getReflect2(p1 : Point, p2 : Point) : Point { var wallvec : Point = g...
My flash app needs to know its own URL, so that it can load some (non-embedded) content using relative paths. (I cannot hardcode the full paths because there will be multiple installs -- staging, production, etc. Nor can I use simple relative paths because there's one legacy install that uses a different relative path (ugh). And I c...
Anyone who has programmed with actionscript 3.0 has most certainly noticed its lack of support for private constructors and abstract classes. There are ways to work around these flaws, like throwing errors from methods which should be abstract, but these work arounds are annoying and not very elegant. (Throwing an error from a method tha...
