flash旋转菜单

工作闲于时间做了个旋转菜单，每个项目都可以添加鼠标消息，现在做的是每个项目在鼠标移上去时加了个发光滤镜，不过还是有点BUG，有关ChildIndex的问题还需要改进，然后某胖子建议我加个减速的物理引擎，说现在看上去太假了，囧。下次再改进改进。。

这里有一个演示版本，在deviantart上，但是图片都是从外部load进去的，所以我就用Sprite代替了。

主类：CircleBar3.as

package {

import flash.display.Sprite;

import flash.display.StageScaleMode;

import flash.display.Loader;

import flash.net.URLRequest;

public class CircleBar3 extends Sprite

{

private var angle:Number=0;

private var centerX:Number=200;

private var centerY:Number=250;

private var menuW:Number=10;

private var menuH:Number=10;

private var radius:Number=200;

private var speed:Number=0.04;

private var menuBar:Array

private var url:Array;

private var urlLoader:Array;

var pointY:Number;

public function CircleBar3()

{

stage.align=StageAlign.TOP_LEFT;

stage.scaleMode=StageScaleMode.NO_SCALE;

init();

}

private function init():void {

menuBar=new Array();

for(var i:int=1; i<=8; i++){

var rectM:loadPic=new loadPic(i.toString()+".png");

menuBar.push(rectM);

addChild(rectM);

}

trace(menuBar.length);

addEventListener(Event.ENTER_FRAME,onEnterFrame);

}

private function onEnterFrame(ent:Event):void {

var pi:Number=Math.PI;

var angle2:Number=pi/4;

var i:int;

for(i=0; i<8;>

var rectM_C:loadPic=menuBar[i];

rectM_C.x = centerX + Math.cos(angle+i*angle2) * radius/3;

var angle3:Number=angle+i*angle2;

rectM_C.scaleX=rectM_C.scaleY=(Math.sin(angle3+pi/2)+1)/5+0.5;

rectM_C.filters=[new BlurFilter((Math.sin(angle3- pi/2)+1)*5,(Math.sin(angle3-pi/2)*20+1),3)];

}

addEventListener(MouseEvent.MOUSE_DOWN,mouseDownHandle);

}

private function mouseDownHandle(evt:MouseEvent) {

stage.addEventListener(MouseEvent.MOUSE_MOVE,mouseMoveHandle);

stage.addEventListener(MouseEvent.MOUSE_UP,mouseUpHandle);

pointY=mouseY;

}

private function mouseMoveHandle(evt:MouseEvent) {

}

else{

angle += speed;

pointY=mouseY;

}

}

private function mouseUpHandle(evt:MouseEvent) {

stage.removeEventListener(MouseEvent.MOUSE_MOVE,mouseMoveHandle);

}

}

}

加载图片，并添加鼠标消息：loadPic .as

package {

import flash.display.Sprite;

import flash.display.Loader;

import flash.net.URLRequest;

import flash.events.Event;

import flash.events.MouseEvent;

import flash.display.Bitmap;

import flash.display.BitmapData;

import flash.filters.GlowFilter;

public class loadPic extends Sprite {

var _sprite:SingleMenu;

var _loader:Loader;

var _string:String;

public function loadPic(_string:String) {

this._string=_string;

init();

}

private function init():void {

_loader=new Loader();

_loader.contentLoaderInfo.addEventListener(Event.COMPLETE,loadedImage);

_loader.load(new URLRequest(_string));

}

private function loadedImage(evt:Event):void {

var loadedimg:Bitmap=Bitmap(_loader.content);

_sprite=new SingleMenu();

_sprite.addChild(loadedimg);

addChild(_sprite);

_sprite.addEventListener(MouseEvent.MOUSE_OVER,rollover);

}

private function rollover(evt:MouseEvent) {

evt.currentTarget.filters=[new GlowFilter(0xffffff,0.5,20,20,2,1,false,false)];

evt.currentTarget.addEventListener(MouseEvent.MOUSE_OUT,mouseOutHandle);

}

private function mouseOutHandle(evt:MouseEvent) {

evt.currentTarget.filters=[];

}

}

}

图片加载容器：SingleMenu.as

package {

import flash.display.Sprite;

public class SingleMenu extends Sprite {

var smenu_w:Number;

var smenu_h:Number;

var color:uint;

public function SingleMenu(smenu_w:Number=128, smenu_h:Number=128,color:uint=0xffffff) {

this.smenu_w = smenu_w;

this.smenu_h = smenu_h;

this.color = color;

init()

}

private function init():void {

graphics.beginFill(color,0);

graphics.drawRect(5, 5, smenu_w, smenu_h);

graphics.endFill();

}

}

}
