我有这个 AS2 代码,当我使用 TweenLite 翻转 mc 时,它会执行一些简单的动画。

我觉得我有很多重复的代码。

有没有办法可以只指定这样的功能

框链接(一);

并有其余的代码,在函数中而不是在函数变量中具有目标影片剪辑的路径?

我怎样才能使这段代码尽可能短?

是否可以将变量:String 转换为变量:MovieClip?在这个例子中我会怎么做?

 import gs.*;
 import gs.easing.*;


function imageAlpha(mc_target:MovieClip) {
    mc_target.onRollOver = function() {
            TweenLite.to(mc_target,1,{_alpha:100, ease:Back.easeOut});
    };

    mc_target.onRollOut = function() {
            TweenLite.to(mc_target,1,{_alpha:60, ease:Back.easeOut});
    };
 }



  function boxLink(mc_function:MovieClip, mc_target:MovieClip, mc_image:MovieClip, linkURL:String) {
    mc_function.onRollOver = function() {
            TweenLite.to(mc_target,0.5,{_xscale:150, _yscale:150, ease:Back.easeOut});
            TweenLite.to(mc_image,1,{_alpha:100, ease:Back.easeOut});
    };

    mc_function.onRollOut = function() {
            TweenLite.to(mc_target,0.5,{_xscale:100, _yscale:100, ease:Back.easeOut});
            TweenLite.to(mc_image,1,{_alpha:60, ease:Back.easeOut});
    };

    mc_function.onRelease = function() {
            if (linkURL) {
            getURL(linkURL);
            }
    };
 }



 imageAlpha(a_box.image);
 imageAlpha(b_box.image);
 imageAlpha(c_box.image);
 imageAlpha(d_box.image);

 boxLink(a_box.link1,a_box.arrow1,a_box.image,'http://www.google.no');
 boxLink(a_box.link2,a_box.arrow2,a_box.image,'http://www.google.no');
 boxLink(a_box.link3,a_box.arrow3,a_box.image,'http://www.google.no');

 boxLink(b_box.link1,b_box.arrow1,b_box.image,'http://www.google.no');
 boxLink(b_box.link2,b_box.arrow2,b_box.image,'http://www.google.no');
 boxLink(b_box.link3,b_box.arrow3,b_box.image,'http://www.google.no');

 boxLink(c_box.link1,c_box.arrow1,c_box.image,'http://www.google.no');
 boxLink(c_box.link2,c_box.arrow2,c_box.image,'http://www.google.no');
 boxLink(c_box.link3,c_box.arrow3,c_box.image);

 boxLink(d_box.link1,d_box.arrow1,d_box.image,'http://www.google.no');
 boxLink(d_box.link2,d_box.arrow2,d_box.image,'http://www.google.no');
 boxLink(d_box.link3,d_box.arrow3,d_box.image);

使用数组而不是命名变量

a_box.link_1, a_box.link_2, ..., a_box.link_3 

变成

a_box.link[ i ] where i = 0 to n-1, n = number of links

箭头也是如此。

接下来,为boxLink()

public function 
boxLinkWrapper(x:BoxType, url:string='http://www.google.no') :ReturnType {
    for (i:int = 0; i < x.link.size; ++i) {
        boxLink(x.link[ i ], x.arrow[ i ], x.image, url);
    }
}

此外,由于您有许多这样的框,请将它们放在一个数组中:

var boxes:Array = new Array();
boxes.push(new Box("a")); //a_box
boxes.push(new Box("b")); //b_box

并总结每个盒子所需的步骤:

public function 
processBox(x:BoxType):SomeReturnType {
    imageAlpha(d_box.image);
    boxLink(a_box.link1,a_box.arrow1,a_box.image,'http://www.google.no');
}

并在数组框上运行 for 循环,或使用 forEach() 成员函数:

boxes.forEach(processBox);

不要忘记将 BoxType、SomeReturnType 和 ReturnType 替换为适当的类型。这有帮助吗?(注意:这是未经测试的代码,但应该可以帮助您入门!)
