把as2.0的代码改成3.0的

if (n < 25)
{
n = n + 1;
aa = "y" add n;
duplicateMovieClip("yellow", aa, n * 3);
setProperty(aa, _rotation, random(360));
bb = "r" add n;
duplicateMovieClip("red", bb, n * 3 + 1);
setProperty(bb, _rotation, random(360));
cc = "b" add n;
duplicateMovieClip("blue", cc, n * 3 + 2);
setProperty(cc, _rotation, random(360));
dd = "g" add n;
duplicateMovieClip("green", dd, n * 3 + 3);
setProperty(dd, _rotation, random(360));

}
else
{
n = 0;
gotoAndPlay(3);
} // end else if
