Question

我有三个框架“800”，“450”和“635”

我更新了代码，它现在每1秒跳转到帧到帧。那不是我需要的。我需要计数器达到0并且它跳到一帧然后停在那里。多数民众赞成。

AS3 -

var fromFrame:int = 1;
var myTimer:Timer = new Timer(1000, nCount);
var frameNum:int = Math.ceil(Math.random() * mcYourScore.totalFrames)

timer_txt.text = nCount.toString();
myTimer.start();

myTimer.addEventListener(TimerEvent.TIMER, countdown);

function getRandomFromRange(minValue:Number, maxValue:Number):int {
return Math.round(minValue + Math.random() * (maxValue - minValue));
}

function countdown(e:TimerEvent):void {
//Display countdown
timer_txt.text = String(myTimer.repeatCount - myTimer.currentCount);
//if End of countdown, start from 2 frame
fromFrame = (myTimer.repeatCount == myTimer.currentCount) ? 2 : 1;
mcYourScore.gotoAndStop(getRandomFromRange(fromFrame, mcYourScore.totalFrames)); 
}

Answer 1

Math.round（Math.random（））没有任何意义，它只返回0或1个值。

var frameNum:int = Math.round(1 + Math.random() * (mcYourScore.totalFrames-1));

如果您想在每个刻度线上访问随机帧，这种结构应该可以帮助您：

var seconds:int;

function getRandomFromRange(minValue:Number, maxValue:Number):int {
    return Math.round(minValue + Math.random() * (maxValue - minValue));
}

function countdown(e:TimerEvent):void {
    //Display countdown
    seconds = myTimer.repeatCount - myTimer.currentCount;
    timer_txt.text = seconds.toString();
    //if End of countdown, start from 2 frame
     mcYourScore.gotoAndStop(getRandomFromRange(((seconds == 0) ? 2 : 1), mcYourScore.totalFrames));
}

如果您只想在倒计时结束时访问随机帧，可以使用TimerEvent.TIMER_COMPLETE事件处理程序，或更改countdown逻辑：

function countdown(e:TimerEvent):void {
    //Display countdown
    timer_txt.text = String(myTimer.repeatCount - myTimer.currentCount);
    //if End of countdown, pick random frame, from 2 frame
    if(myTimer.repeatCount == myTimer.currentCount){
        mcYourScore.gotoAndStop(getRandomFromRange(2, mcYourScore.totalFrames));
    }
}

定时器加载随机帧不起作用
