AS3常用代码片

1、全屏语句

stage.displayState = StageDisplayState.FULL_SCREEN; 

2、广播事件

//侦听事件EventDispatcherEx.dispatcher.addEventListener("returnManyou", ljTo);function ljTo(e){//ljt.gotoAndStop(p.frameNum);//执行相应的操作}//广播事件EventDispatcherEx.dispatcher.dispatchEvent(new Event("returnManyou"));//EventDispatcherEx 类package {import flash.events.EventDispatcher;public class EventDispatcherEx{public static const dispatcher:EventDispatcher = new EventDispatcher;public function EventDispatcherEx(){}}}

3、加载外部背景音乐并循环播放

import flash.media.SoundChannel;import flash.media.Sound;import flash.net.URLRequest;import flash.events.Event;var soundM:Sound=new Sound();var soundct:SoundChannel=new SoundChannel();soundM.load(new URLRequest("bgmusic.mp3"));soundct=soundM.play();soundct.addEventListener(Event.SOUND_COMPLETE,onComplete);function onComplete(eve:Event):void{soundct=soundM.play();soundct.addEventListener(Event.SOUND_COMPLETE,onComplete);} 

4、引用OSMultiTouch.swc库实现两点触摸效果

import com.lylib.touch.OSMultiTouch;import com.lylib.touch.gestures.DirectionGesture;import com.lylib.touch.events.DirectionEvent;import com.lylib.touch.gestures.*;import com.lylib.touch.events.ZoomEvent;import com.lylib.touch.events.RotateEvent;import com.lylib.touch.events.*;var multiTouch:OSMultiTouch = OSMultiTouch.getInstance();multiTouch.enableGesture (tvClip1, new ZoomGesture(), onZoomGesture); //缩放multiTouch.enableGesture (tvClip1, new RotateGesture(), onRotateGesture); //旋转multiTouch.enableGesture (tvClip1, new DragMoveGesture(), onDragGesture); //拖动function onZoomGesture (e:ZoomEvent):void{e.target.scaleX *=  e.deltaScale;e.target.scaleY *=  e.deltaScale;}function onRotateGesture (e:RotateEvent):void{e.target.rotation +=  e.deltaAngle * 180 / Math.PI;}function onDragGesture (e:DragMoveEvent):void{e.target.x +=  e.deltaOffsetX;e.target.y +=  e.deltaOffsetY;}

5、fla中视频文件声音大小控制语言

//fla中视频音量控制var ylkz:SoundTransform = new SoundTransform();ylkz.volume = num;   //num为你想要的音量大小0~1tvmc.soundTransform = ylkz;   //tvmc 为加载了一个视频的MovieClip影片

6、在卸载子swf时清空内存(听说不算好，但好像还是有用的)

function GC() {    try {          var lc1:LocalConnection = new LocalConnection();          var lc2:LocalConnection = new LocalConnection();          lc1.connect('name');          lc2.connect('name2');     }catch (e:Error){         } }

7、360度序列帧拨动播放

stop();var preMouse:Number; //鼠标位置var frameNum:int = 1; //当前帧var dist:Number = 8; //在屏上滑动多远距离跳一帧 this.addEventListener(MouseEvent.MOUSE_DOWN,downHandler);this.addEventListener(MouseEvent.MOUSE_UP,upHandler);this.addEventListener(MouseEvent.MOUSE_OUT,outHandler);function downHandler(event:MouseEvent):void{preMouse = mouseX;this.addEventListener(MouseEvent.MOUSE_MOVE,moveHandler);}function moveHandler(event:MouseEvent):void{if(mouseX - preMouse > dist){frameNum ++;if(frameNum < totalFrames){this.nextFrame();}else{this.gotoAndStop(1);frameNum = 1;}preMouse = mouseX;}if(mouseX - preMouse < -dist){frameNum --;if(frameNum > 1){this.prevFrame();}else{this.gotoAndStop(totalFrames);frameNum = totalFrames;}preMouse = mouseX;}}function upHandler(event:MouseEvent):void{this.removeEventListener(MouseEvent.MOUSE_MOVE,moveHandler);}function outHandler(event:MouseEvent):void{this.removeEventListener(MouseEvent.MOUSE_MOVE,moveHandler);}

字符串去掉前后空格

//var src:String=" Hello! ";  //trace("\""+src+"\"");    //原文本  //trace("\""+src.replace(/^\s*/g,"")+"\"");    //去掉前面的空格  //trace("\""+src.replace(/\s*$/g,"")+"\"");    //去掉后面的空格

保存图片到本地，有弹出文件保存框的方式，主要用到FileReference类，感谢 flash023

//import com.adobe.images.JPGEncoder;function save(defaultFileName:String = null):void {        var _fileRef:FileReference=new FileReference();//用于保存文件        var _encoder:JPGEncoder=new JPGEncoder(80);//用于编码位图        var bitmapData:BitmapData=new BitmapData(stage.stageWidth,stage.stageHeight);        bitmapData.draw(this);//得到位图        var ba:ByteArray=_encoder.encode(bitmapData);//编码成JPG图片，质量为80        _fileRef.save(ba, defaultFileName);//保存到磁盘，会出现个系统保存对话框。        ba.clear();}function onClick(_evt:MouseEvent ):void {        save("flash023.jpg");}bg.addEventListener("click",onClick);

根据url打开浏览器

var url:URLRequest = new URLRequest("http://www.shao-ming.cn"); navigateToURL(url,"_blank");
