HoloToolKit無法通過父物體集中處理子物體的點擊等事件，本文介紹了如何封裝Hololens點擊事件在父物體上集中處理，大概步驟為：

• 拖入HoloLensCamera預設體

• 拖入InputManager預設體
• 拖入Cursor預設體
• 創建畫布
• 創建兩個Button

1-3. 拖入三個預設體

4. 創建畫布

創建完畫布后，把 Render Mode 設為 World Space

添加CanvasCtrl.cs腳本

using UnityEngine;

public class CanvasCtrl : MonoBehaviour
{
    private TapEvent m_Button1;
    private TapEvent m_Button2;
    private void Awake()
    {
        m_Button1 = transform.FindChild("Button1").GetComponent<TapEvent>();
        m_Button2 = transform.FindChild("Button2").GetComponent<TapEvent>();
        m_Button1.hololensOnClick.AddListener(OnButton1Click);
        m_Button2.hololensOnClick.AddListener(OnButton2Click);
    }

    private void OnButton1Click()
    {
        Debug.Log("OnButton1Click");
    }

    private void OnButton2Click()
    {
        Debug.Log("OnButton2Click");
    }
}     

5. 創建兩個Button

兩個按鈕都添加TapEvent.cs腳本

using UnityEngine;
using UnityEngine.Events;
using HoloToolkit.Unity.InputModule;
public class TapEvent : MonoBehaviour,IInputClickHandler
{
    [SerializeField]
    private UnityEvent HololensOnClick = new UnityEvent();

    public UnityEvent hololensOnClick
    {
        get { return HololensOnClick; }
        set { hololensOnClick = value; }
    }

    public void OnInputClicked(InputEventData eventData)
    {
        HololensOnClick.Invoke();
    }
}

測試結果
