填入一个正确的flex builder3的 序列号 还有 自己有邮箱

系统吧生成的 序列号发到你填入的邮箱。

我生成的是

关于addChild
比如你创建了一个圆形的sprite;
var mySprite:Sprite = new Sprite();
mySprite.graphics.beginFill(0xff0000);
mySprite.graphics.drawCircle(0, 0, 40);
mySprite.graphics.endFill();
但是这么写是不回被显示的
在as3中创建了一个sprite后不会自动被加入显示列表,
使用addChild方法把对象加入显示;

使用removeChild删除显示列表中的一个对象
addChild(mySprite);

完成的创建和点击他以后删除一个sprite;

package action{
    import flash.display.Sprite;
    import flash.events.*;
    public class DrawRemove extends Sprite {
        var mySprite:Sprite = new Sprite();
        var centerX:Number=stage.stageWidth/2;
        var centerY:Number=stage.stageHeight/2;
        public function DrawRemove() {
            trace(stage.stageWidth+stage.stageHeight);
            mySprite.graphics.beginFill(0xff0000);
            mySprite.graphics.drawCircle(centerX, centerY, 40);
            mySprite.graphics.endFill();
            addChild(mySprite);
            mySprite.addEventListener(MouseEvent.MOUSE_DOWN, mouseDownHandler);
        }
        private function mouseDownHandler(event:MouseEvent):void {
            removeChild(mySprite);
        }
    }
}

[转]假如您想学FLASH [ 2006-10-4 10:05:19 | 作者:love黄家驹 | 出处:转贴 | 天气:晴 ] 假如您想学FLASH，你会负出巨大代价！ flash是个做动画的软件，所以PS你得会，好图片才能做出好动画效果啊；手绘你得会，要不怎么做逐帧动画；要想做出好的动画，3D效果得有， 3Dmax，maya得学，AE，Premiere得会，要不怎么导视频和声音，什么swift3D,swishmax都是小场面，flash做出来得发布把，学习做网页得加紧啊，html,asp,php都得了解。flash有编程，AS得熟啊，与数据库对联咱得明白啊，什么xml，javasript 得知道啊。flash有自己的服务器建设方法，什么FMS，Flex啊，得跟上啊。所以想学flash……

Stage 类是一个顶级类此类的方法和属性用于访问和操作有关 SWF 文件边界的信息。

this.createTextField("stageSize_txt", this.getNextHighestDepth(), 10, 10, 100, 22); var stageListener:Object = new Object();stageListener.onResize = function() { stageSize_txt.text = "w:"+Stage.width+", h:"+Stage.height;}; Stage.scaleMode = "noScale"; Stage.addListener(stageListener);//一个检测flashwidth heignt的帧听器

static指定某个变量或函数只为每个类创建一次，而不是在基于该类的每个对象中都创建。

class Users { 
 private static var numInstances:Number = 0; 
 function Users() { 
 numInstances++; 
 } 
 static function get instances():Number { 
 return numInstances; 
 } 
}
