3D旋轉菜單目前好像滿火的，正好自己也做了一個，分享一下吧（感謝gotoAndLearn提供視頻下載）
先來看看效果吧：click here（忘了做loading了
）
先來說說思路，首先要形成一個橢圓軌跡，這個函數可以這樣寫
複製內容到剪貼板
cos是鄰邊比斜邊，所以對應_x，同理sin對應_y，這裏的r_x和r_y分別是在函數外定義的橢圓的x半徑和y半徑，c_x和c_y是橢圓的中心代碼:
function move_me() {
this._x = Math.cos(this.angle)*r_x+c_x;
this._y = Math.sin(this.angle)*r_y+c_y;
this.angle += speed;
ratio = this._y/(r_y+c_y);
this._xscale = this._yscale=ratio*100;
this.swapDepths(ratio*100+100);
}縮放比例是採用y座標與橢圓的y半徑與橢圓的中心之和
這樣再加個onEnterFrame，就可以旋轉了，當然要先將參數定義好
如果要多個不同的mc進行旋轉的話，其實也很好辦，只要事先分配給每一個mc一個angle就行了
複製內容到剪貼板
item_num是先前定義的mc的數量代碼:
for (var i = 0; i<item_num; i++) {
var t:MovieClip = home.attachMovie("item", "item"+i, i+1);
t.angle = (i/item_num)*(Math.PI*2);
}倒影那塊，倒是卡了我一段時間，原來要實現漸變遮罩，要將遮罩與遮罩都啓用位圖緩存
還要說一下，上面這個item其實只是個殼，裏面有icon_mc，和ref_mc，而這兩個也還是殼，真正要執行loadMovie的其實是t.icon_mc.icon_loader和t.ref_mc.ref_loader，爲什麼要這麼做呢，一層套一層多麻煩，開始我也這麼認爲，所以直接用t.icon_mc來loadMovie，結果遮罩失效。
裏面還用到了easing類，這個是在點擊mc時要使用的。
最後還有一個難點就是提示效果，這裏用到了Delegate類，她的作用就是定義函數的作用域。
爲了方便修改，所以採用了xml載入的方式
全部的AS：

Mouse.addListener(mouseListener);感覺鼠標移出場景和移入場景那塊，處理的不是很完美
