你好，所以我一直在寻找解决我的问题的方法，但看起来好像什么都没有。

我正在处理一个场景，在这个场景中，我在地平面上渲染了一些3D对象，我的目标是在那个3D对象上制作动画，首先点击它。我正在使用最新版本的vuforia 10.4和Unity 2020.3。9f1。我有一个脚本，用于实例化3d模型，并使“平面查找器”消失，只要它不丢失跟踪`使用系统。收藏；使用系统。收藏。通用的使用UnityEngine；

公共类的场景管理器：MonoBe行为{私有字符串级别="蛇"；

public GameObject[] renderredPrefab;
public GameObject ground;
public GameObject groundFinder;

private int levelChecker(string levelName)
{
    if (levelName == "snake")
        return 0;

    else return 1;
}

public void spawnObject(int i)
{
    Instantiate(renderredPrefab[levelChecker(level)], new Vector3(0, 0, 0), Quaternion.identity, ground.transform);
}

public void groundFinderOff()
{
    groundFinder.SetActive(false);
}

public void groundFinderOn()
{
    groundFinder.SetActive(true);
}

}和另一个使用System.集合；使用System.收藏。通用；使用UnityEngine；

公共类动画师：单行为{私人动画师m_Animator；

private string objectName;
private GameObject[] eos;
private GameObject snake;

[SerializeField]
private Camera ARCamera;

// Start is called before the first frame update
void Start()
{
    // Get the different eos present on the scene
    for (int i = 0; i < eos.Length; i++)
    {
        eos[i] = GameObject.FindWithTag("myEolienne" + i);
    }

    // Get snake game objecct in the scene
    snake = GameObject.FindWithTag("Snake");
}

// Update is called once per frame
void Update()
{
    if (Input.touchCount > 0 && Input.touches[0].phase == TouchPhase.Began)
    {
        Ray ray = ARCamera.ScreenPointToRay(Input.GetTouch(0).position);

        if (Physics.Raycast(ray, out RaycastHit hit))
        {
            objectName = hit.collider.name;
            Debug.Log("raycast touched " + hit.transform.name);
            switch (objectName) //Get the Animator depending on which gameObject been tapped on.
            {
                case "myEolienne1":
                    m_Animator = eos[0].GetComponent<Animator>();
                    // Launch the animation on the gameObject that's been tapped 
                    m_Animator.SetTrigger("Helice_Rotate");
                    Debug.Log("rotate launched");
                    break;

                case "myEolienne2":
                    m_Animator = eos[1].GetComponent<Animator>();
                    // Launch the animation on the gameObject that's been tapped 
                    m_Animator.SetTrigger("Helice_Rotate");
                    Debug.Log("rotate launched");
                    break;

                case "myEolienne3":
                    m_Animator = eos[2].GetComponent<Animator>();
                    // Launch the animation on the gameObject that's been tapped 
                    m_Animator.SetTrigger("Helice_Rotate");
                    Debug.Log("rotate launched");
                    break;
                case "Snake":
                    m_Animator = snake.GetComponent<Animator>();
                    m_Animator.SetTrigger("snakeMoving");
                    break;
            }
        }
    }
}

} `

请注意，每个3D模型都有不同的部分分组在一个父级中，父级only.enter图像描述上有一个网格碰撞器

渲染效果非常好，但我无法找出光线投射脚本的错误。注意，我第一次尝试在图像目标上使用3D模型，效果很好。

提前感谢！
