我想打印我指向的对象女巫的名称（使用 crosshari）。我写了一些脚本，允许我通过查看对象来突出显示它（包括在下面）。你能告诉我如何添加一行代码吗（打印我指向的对象的名称）？

1.SelectionManager

`public class SelectionManager : MonoBehaviour
{
    [SerializeField] private string selectableTag = "Selectable";

    private ISelectionResponse _selectionResponse;

    private Transform _selection;

    private void Awake()
    {
        _selectionResponse = GetComponent<ISelectionResponse>();
    }

    private void Update()
    {
        if (_selection != null) _selectionResponse.OnDeselect(_selection);

        var ray = Camera.main.ScreenPointToRay(Input.mousePosition);

        _selection = null;
        if (Physics.Raycast(ray, out var hit))
        {
            var selection = hit.transform;
            if (selection.CompareTag(selectableTag) || (selection.CompareTag("Stool_square1")))
            {
                //string name = gameObject.name;
                //print(name);
                _selection = selection;
            }
        }

        if (_selection != null) _selectionResponse.OnSelect(_selection);
    }
}`

2.OutlineSelectionResponse

using UnityEngine;

public class OutlineSelectionResponse : MonoBehaviour, ISelectionResponse
{
    public void OnSelect(Transform selection)
    {
        var outline = selection.GetComponent<Outline>();
        if (outline != null) outline.OutlineWidth = 2;
    }

    public void OnDeselect(Transform selection)
    {
        var outline = selection.GetComponent<Outline>();
        if (outline != null) outline.OutlineWidth = 0;
    }
}

3.ISelectionResponse

using UnityEngine;

internal interface ISelectionResponse
{
    void OnSelect(Transform selection);
    void OnDeselect(Transform selection);
}

【问题讨论】：

无关提示：您应该针对图层蒙版进行光线投射。您当前的代码检查会针对场景中可能很慢的任何对撞机进行检查。 Raycast 函数有一个重载，它接受一个图层蒙版并检查给定图层中对撞机的命中。

【解决方案1】：

试试hit.collider.name之类的东西
