问题 Sorry the title's so convoluted... I must've tried for ten minutes to get a good, descriptive title! Basically, here's the scenario. Let's say a user can pick fifty different hat colors and styles to put on an avatar. The avatar can move his head around, so we'd need the same types of movements in the symbol for when that happens. Additionally, it gets which hat should be on the 'avatar' from a database. The problem is that we can't just make 50 different frames with a different hat on each.

问题 I'm an AS3 noob on training wheels... I have an XML Loader class which is doing what it's supposed to with a test.xml file, however I need the flash to read the xml written by an aspx file. So I tried: var urlRequest:URLRequest = new URLRequest("../xml/CaseStudyFlashAssets.aspx"); I get error #1090 (which I gather is because the aspx is not xml and it doesn't like it) Can anyone help me get to the xml written by the aspx file? Thanks Mikey 回答1: A frequent problem with xml being supplied from

问题 I was testing a HashMap implementation in AS3 . I have tried the following code: var map:IMap = new HashMap(); map.put("a", "value A"); map.put("b", "value B"); map.put("c", "value C"); map.put("x", "value X"); map.put("y", "value Y"); map.put("z", "value Z"); Then I called the clear() method: map.clear(); The size of the hashmap didn't become 0, but it was 1. The problem is that when the key is "y", it doesn't get removed. The corresponding code is as follows: protected var map:Dictionary =

问题 I wish for a movie clip to slowly blur over a couple of seconds. Is there some way to do this without using Tweener or some other external class? I only wish to use the tween class. The code I use at the moment is below, but this doesn't do it gradually, just turns the blur on like a switch: var blur : BlurFilter = new BlurFilter(); blur.blurX = 4; blur.blurY = 4; blur.quality = BitmapFilterQuality.HIGH; chrNicky.filters = [blur]; I need the blur to happen over the course of two seconds.

问题 I have a large project with lots of classes. It takes 40% CPU when it is running. What is the best way to find out what operations and functions are responsible for the load? I am using Flash Builder 4.5 AS3 Project. Built-in profiler doesn't help me much. Thanks 回答1: You can try SWFWire Debugger. Check the box that says Show method entry . If you also check Show method exit , it will tell you how long each function took to execute. The object graph might also help if you are creating and

But it doesn't allow to export any chart or even add an image to excel file. Can anyone recommend me a way of doing this? 回答1: As far as I know there is no way to export a chart to Excel by means of existing libraries. I would like to suggest you one specific way to do it. We all well know that current Office files are stored as collections of XML structures. The

问题 I thought this question would answer my question, but I have applied the following fixes: .as Security.allowDomain("*"); Security.allowInsecureDomain("*"); .html param name="allowScriptAccess" value="always" /> .js params.allowscriptaccess = "always"; And I am still seeing the ExternalInterface.addCallback method fail locally. It works on a web server, or in the dev folder . But not in an arbitrary local folder. 回答1: Add as a trusted location the folder where your swf/html reside. Right click
