最近在写游戏,有个倒计时效果,写个类
import mx.events.EventDispatcher; import mx.utils.Delegate; //倒计时 class game.time.Time { private var _id:Number; private var _second:Number; private var _total:Number; private var dispatchEvent:Function; public var addEventListener:Function; public var removeEventListener:Function; public function Time(s) { EventDispatcher.initialize(this); _second = s; _total = s; } public function getTime() { return _second; } private function timeing() { if (_second>0) { _second--; this.dispatchEvent({type:"onPlay", value:_second}); } else { this.dispatchEvent({type:"onStop", value:_second}); trace("stop") this.stop(); } } public function play() { _id = setInterval(Delegate.create(this, timeing), 1000); } public function stop() { _second = _total; clearInterval(_id); } } 使用 import game.time.Time; //倒计时的时间 var _totalTime = 30; var _time = new Time(_totalTime); _time.addEventListener("onPlay", timeStart); _time.addEventListener("onStop", timeOver); //计时中.. function timeStart(obj) { time = obj.value; score = _score; update(); } //超时,结束游戏 function timeOver() { gotoAndStop("over"); } startBtn.onRelease=function(){ //启动倒计时 _time.play() }
