buttony

基本解释

Button x="17" y="14" label="Button" id="btnSayHello"
s:Button x="17" y="14" label="Button" id="btnSayHello"

對於按鈕的位置，設置影像樹中元素的 x 和 y 屬性。
It is worth noticing how the y coordinate of the popUp window of the vertical menu button is converted from local to global coordinates in the last line of this code fragment.
您有必要了解如何將垂直菜單按鈕的 popUp 窗口的 y 坐標從侷部坐標轉換成全侷坐標（見代碼片段的最後一行）。

Oh, we almost forgot -- they've boosted out the keyboard in favor of a more useful D-pad and A, B, X, Y button formation -- which is, needless to say, awesome for playing awesome games.
