  尝试更改方法调用：

  recipient.SendMessage ("onTouchExit")
  

  我理解“可选”的参数，但突然......

  我建议踩入调试器来检查变量的值 . 也许在某处Null . 在任何情况下，您都可以了解未调用哪种方法 .

  我只是使用Unity方法让它工作

  void OnMouseDown（）{

  // ...在这里写下你的东西，点击后执行

  }

  好吧，经过多次摆弄和头部冲击，我设法弄明白了 . 我发布了一些对我有用的东西，因为一些可怜的未来灵魂可以从中获得一些 Value .

  我会回答我自己的问题，希望任何追随我的人都会觉得这很有帮助 .

  以下代码对我有用 . 将 touchableGameObject.cs 附加到游戏对象并将 touchableManager.cs 附加到ARCamera .

  touchableGameObject.cs：

  using UnityEngine;
  using System.Collections;
  
  public class touchableGameobject : MonoBehaviour
  {
      public Color defaultColor;
      public Color selectedColor;
      private Material mat;
  
      void Start()
      {
          mat = GetComponent<Renderer>().material;
      }
  
      void onTouchDown()
      {
          mat.color = selectedColor;
      }
  
      void onTouchUp()
      {
          mat.color = defaultColor;
      }
  
      void onTouchStay()
      {
          mat.color = selectedColor;
      }
  
      void onTouchExit()
      {
          mat.color = defaultColor;
      }
  }
  

  touchableManager.cs

  using UnityEngine;
  using System.Collections;
  using System.Collections.Generic;
  
  public class touchableManager : MonoBehaviour
  {
      public LayerMask touchInputMask;
      private List<GameObject> touchList = new List<GameObject>();
      private GameObject[] touchesOld;
      private RaycastHit hit;
  
      void Update ()
      {
          if (Input.touchCount > 0)
          {
              touchesOld = new GameObject[touchList.Count];
              touchList.CopyTo(touchesOld);
              touchList.Clear();
  
              foreach (Touch touch in Input.touches)
              {
                  Ray ray = Camera.main.ScreenPointToRay(touch.position);    //attached the main camera
  
                  if (Physics.Raycast(ray, out hit, Mathf.Infinity, touchInputMask.value))
                  {
                      GameObject recipient = hit.transform.gameObject;
                      touchList.Add(recipient);
  
                      if (touch.phase == TouchPhase.Began) {
                          Debug.Log("Touched: " + recipient.name);
                          recipient.SendMessage ("onTouchDown", hit.point, SendMessageOptions.DontRequireReceiver);
                      }
  
                      if (touch.phase == TouchPhase.Ended) {
                          recipient.SendMessage ("onTouchUp", hit.point, SendMessageOptions.DontRequireReceiver);
                      }
  
                      if (touch.phase == TouchPhase.Stationary || touch.phase == TouchPhase.Moved) {
                          recipient.SendMessage ("onTouchStay", hit.point, SendMessageOptions.DontRequireReceiver);
                      }
  
                      if (touch.phase == TouchPhase.Canceled) {
                          recipient.SendMessage ("onTouchExit", hit.point, SendMessageOptions.DontRequireReceiver);
                      }
                  }
              }
              foreach (GameObject g in touchesOld)
              {
                  if (!touchList.Contains(g))
                  {
                      g.SendMessage("onTouchExit", hit.point, SendMessageOptions.DontRequireReceiver);
                  }
              }
          }
      }
  }
  

  此外，在Unity编辑器的右上角，单击“图层”下拉列表 . 编辑图层 . 我只是在字段中键入“触摸输入”（例如，用户第8层，或任何可用的内容） . 然后，选择ARCamera并在“检查器”选项卡中，在“图层”下拉列表中选择新命名的图层 . 对每个GameObject执行相同操作 . 此外，在ARCamera中，在“touchableManager”组件下，您还必须在“触摸输入掩码”下拉列表中选择新命名的图层 .

  希望这有助于某人 .
