Egret引擎的常用倒计时

直接上代码，

1private timeControl() { 
2        let timer: egret.Timer = segret.Timer(1000);
3        timer.addEventListener(egret.TimerEvent.TIMER,(event:egret.TimerEvent) =>{
4            this.countTotalTime--;
5            if(this.countTotalTime < 0){
6                //this.countDownShow.text = "0";
7                return;
8            }
9            this.countDownShow.text= this.countTotalTime.toString();
10        }, this);
11        timer.start();
12         
13    }
14
15二、
16var count:number = 60;
17var timer:egret.Timer = new egret.Timer(1000,60);//1000代表1秒执行一次，60代表执行60次，这样实现的一分钟计时
18timer.addEventListener(egret.TimerEvent.TIMER,onTimer,this);
19timer.addEventListener(egret.TimerEvent.TIMER_COMPLETE,onTimerComplete,this);
20timer.start();
21function onTimer(evt:egret.TimerEvent):void {
22        count--;
23        console.log("倒计时:"+count);
24}
25function onTimerComplete(evt:egret.TimerEvent):void {
26        console.log("结束");
27}
28三、
29public countDownShow: eui.Label;
30private timer;
31private timeControl(second) {
32    if (second > 0) {
33        this.countDownShow.visible = true;
34        this.timer = egret.setInterval(function () {
35            if (second > 1) {
36                second--;
37                this.countDownShow.text = second.toString();
38                }
39            }, this, 1000);
40            if (second <= 1) {
41                console.log("停止计时");
42                clearInterval(this.timer);
43                this.countDownShow.visible = false;
44            }
45        }
