這篇教程主要向大家講解如何利用Flash AS3代碼打造絢爛的星形變幻效果，教程并沒有對每一個代碼做出講解，但也不是很難，分享到武林網，喜歡的朋友一起來學習吧！　

復制代碼

代碼如下:

package
　{
　import flash.display.Sprite;
　import flash.events.Event;
　import flash.events.MouseEvent;
　[SWF(backgroundColor = "0x000000", frameRate = "60")]

　{
　private var patternList:Array = new Array();
　private var moveBullet:Array = new Array();
　public function Main():void
　{
　if (stage) init();
　else addEventListener(Event.ADDED_TO_STAGE, init);
　}
　private function init(e:Event = null):void
　{
　removeEventListener(Event.ADDED_TO_STAGE, init);
　// entry point
　MouseDown(null);
　addEventListener(Event.ENTER_FRAME, EnterFrame );
　stage.addEventListener(MouseEvent.MOUSE_DOWN, MouseDown);
　}
　private function EnterFrame(event:Event):void
　{
　var i:int = 0;
　for ( i = 0; i < patternList.length; i++ )
　{
　var bullet:Bullet = patternList[i].Run();
　if ( bullet != null )
　{
　addChild( bullet );
　}
　}
　for ( i = patternList.length - 1; i >= 0; i-- )
　{
　if ( patternList[i].isEnd() )
　{
　// 從待命到移動
　for ( var j:int = 0; j < patternList[i].waitBullet.length; j++ )
　{
　patternList[i].waitBullet[j].StartSlide();
　moveBullet.push( patternList[i].waitBullet[j] );
　}
　patternList.splice( i, 1 );
　}
　}
　// 移動
　if ( moveBullet.length > 0 )
　{
　for ( i = moveBullet.length - 1; i >= 0; i-- )
　{
　//

　{
　moveBullet[i]._xx += Math.cos( moveBullet[i].slideAngle * Math.PI / 180 ) * moveBullet[i].slideSpeed;
　moveBullet[i]._xy += Math.sin( moveBullet[i].slideAngle * Math.PI / 180 ) * moveBullet[i].slideSpeed;
　moveBullet[i].x = moveBullet[i]._xx;
　moveBullet[i].y = moveBullet[i]._xy;
　if ( moveBullet[i].slideSpeed > 0 )
　{

　if ( moveBullet[i].x < -50 || moveBullet[i].x > stage.stageWidth + 50 || moveBullet[i].y < -50 || moveBullet[i].y > stage.stageHeight + 50 )
　{
　removeChild( moveBullet[i] );
　moveBullet.splice( i, 1 );
　}
　}
　}
　}
　}
　private function MouseDown(event:MouseEvent):void
　{
　// 小星
