1.前置作業:

主旨:
使用PC跟Arduino版製作互動小遊戲,玩法是利用麥克風聲控來關閉遊戲內物件,請看影片https://www.youtube.com/watch?v=aFHmrqDpOZ0

vuforia frame markers提供512組定義好的辯識物可以直接使用,不需要在vuforia後台製作,但是需要將FrameMarker這東西拉到場景上並且設定好ＩＤ.但是這次筆者需要使用512組總不能一個一個拉吧！
於是就動態生成吧！經過測試可以在ＡＮＤＲＯＩＤ跟ＩＯＳ使用,請注意markerTracker = (MarkerTracker)TrackerManager.Instance.GetTracker<MarkerTracker>();
