Now under the previous logic i loaded two images (let's say circles) of the same size one that has a particular color and is covered by its black foreground circle. When i press left mouse button and hold it down i want while the mouse is moved to erase the foreground circle's pixels and so the

问题 How do I determine if the delete key was pressed using actionscript? addEventListener(KeyboardEvent.KEY_UP, onKeyUp); ... function onKeyUp(event:KeyboardEvent):void { trace(event.keyCode); } The above code yields no value when delete, backspace, enter, and other command keys are pressed. However, arrow keys do yield values. 回答1: this.stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyPressed); .... function onKeyPressed(event:KeyboardEvent):void { if (event.keyCode==Keyboard.DELETE) { .....

问题 I'm scaling onstage MovieClips via AS properties "scaleX" or "scaleY", which kills any kind of animation the clips have within their container MovieClip, be it Classic or Motion Tweens. When I don't scale the MovieClips, they animate fine. I'm able to tell the clips to "gotoAndStop" on their own internal frames, and that doesn't affect their animation within their container clip. I'm referencing the clips via AS w/ their instance names defined in the IDE. I've also tried different clips and

问题 Is there an unofficial spec anywhere that explains how to reverse engineer a Flash .FLA file? I'm specifically interested in creating an application that can "auto-scene plan" a Flash document programmatically, pulling in content from other files, arranging that content into layers, without needing the Flash IDE open. Animators would then be able to take these pre-assembled FLA's and begin animating them. I've already built a JSFL script that does this, but it runs very slowly, is difficult

问题 Is there a way ActionScript 3 can detect the user's screen resolution? 回答1: have a look at stage.fullScreenHeight and stage.fullScreenWidth 回答2: These will return the numbers to your output window: trace(Capabilities.screenResolutionX); trace(Capabilities.screenResolutionY); 回答3: If you are on AIR, you could use the flash.display.Screen class, which contains this info, plus a lot more, such as color-depth, and multi-screen support. 回答4: flash.system.Capabilities.screenResolutionY and flash

问题 i am currently making a flash "pond" with fishes in it, and i have the ability to add food pellets onto the pond, how should i make the movement of my fishes to the food x,y location ? so it will be smooth , rather than setting the x,y location of my fishes to the x,y location of the food pellets. Also is there a good place to learn how to make my fishes move by its own? similar to http://abowman.com/google-modules/fish/ Fish class package { import flash.display.MovieClip; import flash

问题 I've got a rather simple question about loading in an xml file at runtime in a SWF. I've found a couple different methods to load in the xml. myXml.load("file.xml"); HTTPService object URLStream object What is better way to load an xml file that always has the same name and is located in the same folder as the SWF on the web server? 回答1: I would use URLLoader - I think that's the most lightweight one. The complexity of URLStream is unnecessary as far as a configuration file is concerned.

问题 Stage seems to be unaccessible from my class.. almost like it doesn't want to be reached. I do not know what keeps going wrong. This is the class as I have it right now: package { import flash.events.*; import flash.display.*; import flash.net.*; public class gallery extends Sprite{ private var imgPath:String = 'images/'; private var imgCurrent:int = 0; private var images:Array = new Array(); private var iLoader:Loader; function gallery() { this.addEventListener(Event.ADDED_TO_STAGE,

问题 I have no syntax errors when I run this code. I checked the variables and the functions in the action panel and it works fine. But, when I remove the codes from the action panel, and try to run the .as file nothing happens when I click the button. Here's my code: package { import flash.display.*; import flash.events.MouseEvent; import flash.text.*; import flash.display.MovieClip; public class U1A4_Sommeil extends MovieClip { private var monMessage:TextField = new TextField; private var
