AS3.0第5课-消息队列和消息循环-钢镚(一).docVIP

AS3.0不支持多线程，无法写入死循环（whlie（true）），所以我们需要用消息队列和消息循环的监听方式； 所有输入类（键盘，鼠标等）必须在舞台上添加（MovieClip中） 代码： MainGame类 Packpage { //导入部分，导入我们类中需要的包，因为AS3.0不支持自动导入，所以部分调用的包需要//自己手动导入 import . flash . display . MovieClip ; import .flash .display . Event; import .flash . enents.Event; import . flash .events . KeyboardEvent; import . flash . ui . Keyboard; public class MainGame extends MovieClip { //申请层 private var bj:Background; private var wj:Player; private var gb:Money; private var sd:Rightning; private var m_left:Boolean; private var m_right:Boolean; public function Gamemain() { //构造层 bj = new Background; addChild(bj); wj = new Player; addChild(wj); gb = new Money; addChild(gb); sd = new Rightning; addChild(sd); trace(stage); this.addEventListener(Event.ENTER_FRAME,gameLogic); stage.addEventListener(KeyboardEvent.KEY_DOWN,pressed); stage.addEventListener(KeyboardEvent.KEY_UP,relessed); } //游戏逻辑层 public function gameLogic(e:Event):void { wj.Update(m_left,m_right); gb.Update(); sd.Update(); } public function pressed(e:KeyboardEvent):void { if(e.keyCode == Keyboard.LEFT) { m_left = true; } if(e.keyCode == Keyboard.RIGHT) { m_right = true; } } public function relessed(e:KeyboardEvent):void { if(e.keyCode == Keyboard.LEFT) { m_left = false; } if(e.keyCode == Keyboard.RIGHT) { m_right = false; } } } } Money类 package { import flash.display.MovieClip; public class Money extends MovieClip { //申请层 private var m_v:int; public function Money() { x = Math.random()*230; y = Math.random()*-10-20; m_v = Math.random()*4+5; } //构造层 public function Update():void { y += m_v; if(y 320) { x = Math.random()*230; y = Math.random()*-10-20; m_v = Math.random()*4+5; } } } } Money类 package { import flash.display.MovieClip; public class Player extends MovieClip { //构造层
