Question

我有启动和停止按钮，但我无法弄清楚如何制作重置按钮并让时钟指针移回原位，请提供帮助。以下是我的代码

import flash.utils.Timer;
import flash.events.MouseEvent;
import flash.events.TimerEvent;

var TimerOne: Timer = new Timer(1000);
myStartButton.addEventListener(MouseEvent.CLICK, startTimer);
myStopButton.addEventListener(MouseEvent.CLICK, stopTimer);
myResetButton.addEventListener(MouseEvent.CLICK, resetTimer);
TimerOne.addEventListener(TimerEvent.TIMER, moveHand);

//START BUTTON FUNCTION
function startTimer(e: MouseEvent): void
{
TimerOne.start();
trace("Timer started");
}

function moveHand(e: TimerEvent) : void
{
mySecondHand.rotation = mySecondHand.rotation + 6
myMinuteHand.rotation = myMinuteHand.rotation + 0.1;
}


var TimerTwo: Timer = new Timer(12000);
TimerTwo.addEventListener(TimerEvent.TIMER, moveHourHand);

function moveHourHand(e: TimerEvent) : void
{
myHourHand.rotation = myHourHand.rotation + 0.1;
}

//STOP BUTTON FUNCTION
function stopTimer(e: MouseEvent) : void
{
TimerOne.stop();
TimerTwo.stop();
trace("Timer stopped");
}

这是我试图找出重置计时器的地方

//RESET BUTTON FUNCTION
function resetTimer(e: MouseEvent) : void
{
TimerOne.reset(); 
TimerTwo.reset();
trace("Timer reset");
}

如果说复位意味着将所有手柄（秒，分钟和小时）移动到主要位置，您应该这样做：

function resetTimer(e: MouseEvent) : void
{
    mySecondHand.rotation = 0;
    myMinuteHand.rotation = 0;
    myHourHand.rotation = 0;

    //You shouldn't do anything with your timer if you want it to continue counting.
    //TimerOne.reset(); 
    //TimerTwo.reset();
    trace("Timer reset");
}

假设您的初始句柄旋转为0，则可以正常工作。如果不是，则应将旋转值保存到变量并在重置时使用它们。这看起来像这样：

var TimerOne: Timer = new Timer(1000);
.
.
.
var sRotation:Number = mySecondHand.rotation;
var mRotation:Number = myMinuteHand.rotation;
var hRotation:Number = myHourHand.rotation;
.
.
.
function resetTimer(e: MouseEvent) : void
{
    mySecondHand.rotation = sRotation;
    myMinuteHand.rotation = mRotation;
    myHourHand.rotation = hRotation;
}

我还建议只为所有句柄使用一个计时器（秒，分钟和小时）。我看到你每秒钟移动秒针（1000毫秒）和每小时处理12秒（12000毫秒）所以我建议你这样做：

var hCount:int = 0;
function moveHand(e: TimerEvent) : void
{
    hCount++;
    if(hCount == 12)
    {
        //The following is the same as this: 
        //myHourHand.rotation = myHourHand.rotation + 0.1;
        myHourHand.rotation += 0.1;
        hCount = 0;
    }

    mySecondHand.rotation += 6;
    myMinuteHand.rotation += 0.1;
}

我正在尝试在Flash中为我的时钟添加一个重置按钮
