bullet.as

package { import flash.display.Sprite; import flash.events.Event; public class bullet extends Sprite { private var sw:Number; private var sh:Number; private const _SPEED:int=10; private const _OFFSTAGE:int=-10; public function bullet():void { addEventListener(Event.ADDED_TO_STAGE,onadd); } private function onadd(e:Event):void { sw=stage.stageWidth; sh=stage.stageHeight; addEventListener(Event.ENTER_FRAME,loop); } private function loop(e:Event):void { if (y<_OFFSTAGE) { removeEventListener(Event.ENTER_FRAME,loop); parent.removeChild(this); } y-=_SPEED; } public function removeListeners():void { removeEventListener(Event.ENTER_FRAME,loop); } } }

TimeLine

var sfx_gun:Sound = new sfx(); var sp:MovieClip = new ship(); var bulletholder:Sprite = new Sprite(); addChild(bulletholder); addChild(sp); addEventListener(Event.ENTER_FRAME,onenter); stage.addEventListener(MouseEvent.CLICK,onclick); function onenter(e:Event):void { sp.x-=(sp.x-mouseX)*.1; sp.y-=(sp.y-350)*.2; } function onclick(e:Event) { sfx_gun.play(); sp.y=365; var bl:Sprite = new bullet(); bl.y=sp.y; bl.x=sp.x; bulletholder.addChild(bl); }
