//[メモ]
//papervision3Dのオブジェクトにマウスイベントを反応させるには～
//org.papervision3d.events.InteractiveScene3DEventをimportする
//viewPort3Dのinteractiveをtrueにする
//matrialのinteractiveをtrueにする
//オブジェクトにイベントを追加する
//addEventListener(InteractiveScene3DEvent.OBJECT_OVER, onOver)
//オブジェクト自身の動きはBooleanを使ってonEnter内に書いておく
//Tweenerなどを使うと楽にできるのかな？
//もっと正しいやり方があると思うけど…とりあえず動いたので(笑)
