Question

我从图书馆略去了几部电影片,在电影片片片片片片内,我只想控制它,这里是我的文字。

if (selectDiffText.text == "Collection 1 Easy")
    {
        var c1_easy:cartoonEasy = new cartoonEasy();
        addChild(c1_easy);
        c1_easy.x = 412;
        c1_easy.y = 400;
        TweenMax.from(c1_easy, 0.5, {alpha:0, ease:Expo.easeOut});
    }
    else if (selectDiffText.text == "Collection 1 Medium")
    {
        var c1_medium:cartoonMedium = new cartoonMedium();
        addChild(c1_medium);
        c1_medium.x = 412;
        c1_medium.y = 400;
        TweenMax.from(c1_medium, 0.5, {alpha:0, ease:Expo.easeOut});
    }
else
    {
        trace("ERROR!");
    }

如果改动selectDiffText,上述法律将装上图书馆的特别影片。

var movieList:Array = [cartoonMedium1,cartoonMedium2,cartoonMedium3,cartoonMedium4,cartoonMedium5,cartoonMedium6];

function getRandomMovie():MovieClip
{
    var index:int = Math.floor(Math.random() * movieList.length);
    var mcClass:Class = movieList.splice(index,1)[0];
    return new mcClass();
}
playGame = getRandomMovie();
addChild(playGame);

更不用说,如果将c1_添加到阶段,那么c1_medium也将随意从图书馆中添加1个电影片。

在<>playGame mc, I ve mouseTarget.alpha = 0;...how,我能从根层控制吗? c1 - 麻省也有 mo素=0。

Answer 1

为方便起见,c1_easy 和c1_medium 两者都应扩大同一类别。例如:

class c1_easy extends CartoonGenericClass{[...]}

以及

class c1_medium extends CartoonGenericClass{[...]}

In CartoonGenericClass, you would have the variable mouseTarget. You make this public using the getter/setter:

protected var _mouseTarget:Number;

public function get mouseTarget():Number{
    return _mouseTarget;
}

public function set mouseTarget(value:Number):void{
    // (should probably do some verification on "value" here)
    _mouseTarget.alpha = value;
}

这将使可检索<代码>mouseTarget。 (注:无强调)任何物体均可进入c1_easy或c1_medium<>:



c1_easy.mouseTarget = 0;
c1_medium.mouseTarget = .3;


etc. etc.  This is standard OOP, so it may be time to crack a doc.  HTH!
