问题 Is there a way to know how many arguments an instance of Function can take in Flash? It would also be very useful to know if these arguments are optional or not. For example : public function foo() : void //would have 0 arguments public function bar(arg1 : Boolean, arg2 : int) : void //would have 2 arguments public function jad(arg1 : Boolean, arg2 : int = 0) : void //would have 2 arguments with 1 being optional Thanks 回答1: Yes there is: use the Function.length property. I just checked the

问题 Is there an upper bound to the size of a sprite in as3 / flash 10? I know bitmapData has limitations... 回答1: it seems, that xScale and yScale may not exceed 0x8000 ... size itself also seems to be bound ... i found a limit 0x6666660 ... here the code: package { import flash.display.*; public class Main extends Sprite { public function Main():void { var size:Number = 1; var s:Shape = new Shape(); s.graphics.beginFill(0xFF00FF); s.graphics.drawRect(0, 0, size, size); var old:Number = 0; while

问题 I've been trying to get JSON working with AS3 for a while now, but to no avail. I keep getting the following error when I get the JSON back: TypeError: Error #1034: Type Coercion failed: cannot convert Object@26331c41 to Array. I've tried changing the datatype of the variable "jsonData" to object, which fixes the error, but I'm not entirely sure how I can parse the data. package { import flash.display.Sprite; import flash.net.URLRequest; import flash.net.URLLoader; import flash.events.*;

问题 In PHP there is a setcookie function based to store it. In Flash is it possible ?. If it is possible then how? I want to store value. 回答1: First off: PHP runs on the server and therefore can send the necessary HTTP header to set a cookie, Flash runs in the client's browser and thus can not do the same. However, there is a way to access and store cookies from flash/flex by using the flash.external.ExternalInterface and calling JavaScript functions to get and set cookies. I've developed a class

问题 How can I get a ASP.NET (inc MVC) application talking to a Flex UI over AMF. I am wanting to push approx 100+ records around at a time and AMF would appear to be the way forward, but there doesn't appear to be anything obvious. 回答1: If you're pressed for time, you can just use the RemoteObject to hit a compiled DLL (like WebORB - its free for .NET, but you need a VS copy above Express to compile your classes that you want to expose to Flex) and Retrieve the object that way... Obviously your

问题 In Flash 10/AS3, I added some sound and it seems to be working alright, but I think I'm doing it wrong. I imported the sound into the library, but I believe that it's reloading it from the folder with the swf/sound. I'm loading them like so: var request1:URLRequest = new URLRequest("CLICK8C.mp3"); clickSound = new Sound(); clickSound.addEventListener(Event.COMPLETE, completeHandler); clickSound.load(request1); Is there a way to get it to just load it from the library? 回答1: You need to make

问题 I want my movieclip to play once and stop on the last frame. I use the following code in the loop of my movieclip class. (this is as3) if(currentFrame == 120) stop(); 120 is the last frame. It plays once. but the problem is it goes back to frame 1 again. is there a better method of stopping a movieclip on a particular frame. 回答1: If you want to do it with actionscript and not add a stop() to the last frame on the timeline manually, then you can use the undocumented addFrameScript() method. mc

Read some general books, it will help you to understand what is going on. As to your question
