将鼠标悬停在 ActionScript 3 Flash 中的帮助上答案

【问题描述】：

我对 actionscript 3 非常陌生，但我似乎无法将旧的 action script 转换为最新版本 (as3)。当鼠标悬停在按钮上时，我正在尝试将我的影片剪辑从 alpha（透明）设置为可见。这是我的旧代码。

//btnOver is a gaint button over my screen that is transparent

function btnOver(event:MouseEvent):void{
    button_overlay._visible = false;
on(rollOver){
    minutes_mc._visible = true;
    hours_mc._visible = true;
    seconds_mc._visible = true;
}
on(rollOut){
    minutes_mc._visible = false;
    hours_mc._visible = false;
    seconds_mc._visible = false;
}

这是我在 AS3 中的其余（或全部）代码。

import flash.events.MouseEvent;

var date:Date;
var theDate:Date = new Date(  );
var day = theDate.toLocaleDateString()
var time = theDate.toLocaleTimeString()


addEventListener(Event.ENTER_FRAME, refreshHour);
addEventListener(MouseEvent.ROLL_OVER, btnOver);


function refreshHour(event:Event):void{

    date = new Date();

    hour_mc.rotation = date.getHours()*30 + (date.getMinutes()/2);
    hours_mc.rotation = date.getHours()*30 + (date.getMinutes()/2);
    minutes_mc.rotation = date.getMinutes()*6 + (date.getSeconds()/10);
    minute_mc.rotation = date.getMinutes()*6 + (date.getSeconds()/10);
    seconds_mc.rotation = date.getSeconds()*6 + (date.getMilliseconds()/(1000/6));
    second_mc.rotation = date.getSeconds()*6 + (date.getMilliseconds()/(1000/6));
}

date_txt.text = day;

//btnOver is a gaint button over my screen that is transparent

function btnOver(event:MouseEvent):void{
    button_overlay._visible = false;
on(rollOver){
    minutes_mc._visible = true;
    hours_mc._visible = true;
    seconds_mc._visible = true;
}
on(rollOut){
    minutes_mc._visible = false;
    hours_mc._visible = false;
    seconds_mc._visible = false;
}

我基本上是在做一个闪光手表，当你翻过来时它会发光：)

谢谢乔

【解决方案1】：

const GLOW:GlowFilter = new GlowFilter(0xFF0000);

screen.addEventListener(MouseEvent.ROLL_OVER, _rollOver);
screen.addEventListener(MouseEvent.ROLL_OUT, _rollOut);

function _rollOver(e:Event):void
{
    watch.filters = [GLOW];
}

function _rollOut(e:Event):void
{
    watch.filters = [];
}

【讨论】：

很好，我以前从未想过这样做。太好了，我可以试试这个！

【解决方案2】：

在这里，您需要使用两个功能，一个用于结束，另一个用于输出。示例：

addEventListener(MouseEvent.ROLL_OVER, btnOver);
addEventListener(MouseEvent.ROLL_OUT, btnOut);

function btnOver(event:MouseEvent):void{
    // do everything here you want when the mouse goes over
    button_overlay._visible = true;
    minutes_mc._visible = true;
    hours_mc._visible = true;
    seconds_mc._visible = true;
}

function btnOut(event:MouseEvent):void{
    // do everything here you want when the mouse goes out
    button_overlay._visible = false;
    minutes_mc._visible = false;
    hours_mc._visible = false;
    seconds_mc._visible = false;
}

谢谢！！！！唯一的问题是 _visible 必须是 .visible 再次谢谢！
