问题 Can anyone suggest an easy way of getting all combinations without repeats, and with a varying length ? [0,1,2,3,4] (2's) : [0,1],[0,2],[0,3] ... [3,4] (3's) : [0,1,2],[0,1,3] ... [2,3,4] (4's) : [0,1,2,3],[0,1,2,4] ... [1,2,3,4] 回答1: took me a while but I think I've got it here... this has all the combinations without repeats var arr:Array = [0, 1, 2, 3, 4]; var $allcombos:Array = []; findCombos($allcombos,[],arr); function findCombos($root:Array, $base:Array, $rem:Array):void { for (var i

问题 I've read multiple examples on this, but I just don't get how it works. How does the class know it's THE pre-loader? How does flash know to load one class but not another? How much can I do in a preloader? :-p I'm using FlashDevelop atm and it's generating the project for me - however, from all the examples I checked they didn't explain how it worked either. 回答1: Are you familiar with the Flash timeline? By default, your SWF would have one frame. This frame contains your Preloader.as class.

问题 Because I'm a terrible, bad person who likes to do things differently for no reason, I'd love to be able to do something like mySprite.graphics.drawText(...). As I understand things, the only way to get text currently is to create a TextField and add it as a child of mySprite. In my particular situation I'd rather not do that. Any advice appreciated! ooo 回答1: If you wanted to wrap it up in a method of Sprite I would simply extend the Sprite class, add the function drawText to it. Within that

问题 I'm attempting to load an external SWF that's hosted on a site into a local SWF file. The external SWF is in a password-protected directory using htaccess. Here is the code I'm currently trying to use: var loaderUrlRequest:URLRequest = new URLRequest("http://www.my-website.com/externalFlashFile.swf"); loaderUrlRequest.requestHeaders.push(new URLRequestHeader("Authorization", "Basic " + $Base64.encode("username:password"))); loaderUrlRequest.method = URLRequestMethod.POST; loaderUrlRequest

问题 I wanted to know how I would make a whole symbol (an image) scrollable?

So all I want to do is make an image scroll up and down with a single finger input. Are there any simple methods or sample code anyone could give me? 回答1: There are two ways to make an image scrollable in an AS3 mobile project: using the Pan gesture (two fingers

问题 I'm writing a flash app using the open source tools. I would like to load a data file in to the app and capture a screenshot of the stage on the server. The only part that seems mysterious is running the app on the server. In fact, I don't even care if it's the same app running on the server and in the browser--if I can use the flash stage and drawing routines to produce an image server-side, I'm happy. If I have to delve in to flex, fine. Right now I'm having problems finding any starting
