循环3次然后停止 - 闪存AS3

标签： actionscript-3 flash loops banner

这是我主框架上的代码。我需要页面只能从上到下读取代码3次。即使你能想到我怎么做才能让它停止45秒。对不起，我脑子里死了，再也想不到了。有什么建议吗？

import com.greensock.*;
import com.greensock.easing.*;

import flash.utils.*;

function doStuff() {

    //startValues
    box1.back.rotationY = -90;
    box1.back.alpha=0;

    var flipSpeed:Number = .25; 
    var flipSpeedbea:Number = .04; 

    var tl:TimelineMax = new TimelineMax({delay:2});
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.back, 0, {alpha:1, immediateRender:false}))
    tl.append(TweenMax.to(box1.back, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))
    var tb:TimelineMax = new TimelineMax({delay:4});

    box2.back2.rotationY = -90;
    box2.back2.alpha=0;

    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.back2, 0, {alpha:1, immediateRender:false}))
    tb.append(TweenMax.to(box2.back2, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var ins:TimelineMax = new TimelineMax({delay:6});

    box3.back3.rotationY = -90;
    box3.back3.alpha=0;

    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.back3, 0, {alpha:1, immediateRender:false}))
    ins.append(TweenMax.to(box3.back3, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var per:TimelineMax = new TimelineMax({delay:7});

    person.back_person.rotationY = -90;
    person.back_person.alpha=0;

    per.append(TweenMax.to(person.front_person, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    per.append(TweenMax.to(person.back_person, 0, {alpha:1, immediateRender:false}))
    per.append(TweenMax.to(person.back_person, flipSpeed, {rotationY:0, ease:Linear.easeNone}));

    var bea:TimelineMax = new TimelineMax({delay:7});

    be_a.bea_back.rotationY = -90;
    be_a.bea_back.alpha=0;

    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:90, visible:false, ease:Linear.easeNone}))
    bea.append(TweenMax.to(be_a.bea_back, 0, {alpha:1, immediateRender:false}))
    bea.append(TweenMax.to(be_a.bea_back, flipSpeedbea, {rotationY:0, ease:Linear.easeNone}));
    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:0, visible:true, ease:Linear.easeNone}))

    stop();

    setTimeout(doStuff, 15000);
}

doStuff();

是否可以通过doStuff设置功能仅继续运行45秒？基本上我需要功能“doStuff”每次15秒播放3次。

2 个答案:

答案 0 :(得分：0)

如果您要拨打doStuff 3次，相隔15秒，请从setTimeout内删除对doStuff的呼叫，然后执行以下操作：

var stuffTimer:Timer = new Timer(15000, 2);
stuffTimer.addEventListener(TimerEvent.TIMER, doStuff)
doStuff(null);
stuffTimer.start();

您需要更改doStuff方法以接受TimerEvent：

function doStuff(e:TimerEvent):void
{
    [...]
}

不相关，您应该将导入移出doStuff方法并将它们与第一个导入语句组合在一起。

答案 1 :(得分：0)

第一种解决方案是使用变量作为计数器，这样您就不需要使用Timer：

import com.greensock.*;
import com.greensock.easing.*;

import flash.utils.*;

var box1:Object;
var box2:Object;
var box3:Object;
var person:Object;
var be_a:Object;

function stop() {}

var stuffCount:uint = 0;

function doStuff() {

    stuffCount++;

    //startValues
    box1.back.rotationY = -90;
    box1.back.alpha=0;

    var flipSpeed:Number = .25; 
    var flipSpeedbea:Number = .04; 

    var tl:TimelineMax = new TimelineMax({delay:2});
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.back, 0, {alpha:1, immediateRender:false}))
    tl.append(TweenMax.to(box1.back, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))
    var tb:TimelineMax = new TimelineMax({delay:4});

    box2.back2.rotationY = -90;
    box2.back2.alpha=0;

    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.back2, 0, {alpha:1, immediateRender:false}))
    tb.append(TweenMax.to(box2.back2, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var ins:TimelineMax = new TimelineMax({delay:6});

    box3.back3.rotationY = -90;
    box3.back3.alpha=0;

    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.back3, 0, {alpha:1, immediateRender:false}))
    ins.append(TweenMax.to(box3.back3, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var per:TimelineMax = new TimelineMax({delay:7});

    person.back_person.rotationY = -90;
    person.back_person.alpha=0;

    per.append(TweenMax.to(person.front_person, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    per.append(TweenMax.to(person.back_person, 0, {alpha:1, immediateRender:false}))
    per.append(TweenMax.to(person.back_person, flipSpeed, {rotationY:0, ease:Linear.easeNone}));

    var bea:TimelineMax = new TimelineMax({delay:7});

    be_a.bea_back.rotationY = -90;
    be_a.bea_back.alpha=0;

    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:90, visible:false, ease:Linear.easeNone}))
    bea.append(TweenMax.to(be_a.bea_back, 0, {alpha:1, immediateRender:false}))
    bea.append(TweenMax.to(be_a.bea_back, flipSpeedbea, {rotationY:0, ease:Linear.easeNone}));
    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:0, visible:true, ease:Linear.easeNone}))

    stop();

    if (stuffCount < 3)
    {
        setTimeout(doStuff, 15000);
    }
}

doStuff();

第二个解决方案Timer：

import com.greensock.;
import com.greensock.easing.*;

import flash.events.TimerEvent;
import flash.utils.*;


function doStuff() {

    //startValues
    box1.back.rotationY = -90;
    box1.back.alpha=0;

    var flipSpeed:Number = .25; 
    var flipSpeedbea:Number = .04; 

    var tl:TimelineMax = new TimelineMax({delay:2});
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.back, 0, {alpha:1, immediateRender:false}))
    tl.append(TweenMax.to(box1.back, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tl.append(TweenMax.to(box1.front, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))
    var tb:TimelineMax = new TimelineMax({delay:4});

    box2.back2.rotationY = -90;
    box2.back2.alpha=0;

    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.back2, 0, {alpha:1, immediateRender:false}))
    tb.append(TweenMax.to(box2.back2, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    tb.append(TweenMax.to(box2.front2, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var ins:TimelineMax = new TimelineMax({delay:6});

    box3.back3.rotationY = -90;
    box3.back3.alpha=0;

    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.back3, 0, {alpha:1, immediateRender:false}))
    ins.append(TweenMax.to(box3.back3, flipSpeed, {rotationY:0, ease:Linear.easeNone}))
    ins.append(TweenMax.to(box3.front3, flipSpeed, {rotationY:0, visible:true, ease:Linear.easeNone}))

    var per:TimelineMax = new TimelineMax({delay:7});

    person.back_person.rotationY = -90;
    person.back_person.alpha=0;

    per.append(TweenMax.to(person.front_person, flipSpeed, {rotationY:90, visible:false, ease:Linear.easeNone}))
    per.append(TweenMax.to(person.back_person, 0, {alpha:1, immediateRender:false}))
    per.append(TweenMax.to(person.back_person, flipSpeed, {rotationY:0, ease:Linear.easeNone}));

    var bea:TimelineMax = new TimelineMax({delay:7});

    be_a.bea_back.rotationY = -90;
    be_a.bea_back.alpha=0;

    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:90, visible:false, ease:Linear.easeNone}))
    bea.append(TweenMax.to(be_a.bea_back, 0, {alpha:1, immediateRender:false}))
    bea.append(TweenMax.to(be_a.bea_back, flipSpeedbea, {rotationY:0, ease:Linear.easeNone}));
    bea.append(TweenMax.to(be_a.bea_front, flipSpeedbea, {rotationY:0, visible:true, ease:Linear.easeNone}))

    stop();
}

function onTimer(event:TimerEvent):void
{
    doStuff();
}

var myTimer:Timer = new Timer(15000, 3);
myTimer.addEventListener(TimerEvent.TIMER, onTimer);
myTimer.start();
doStuff();
