unity 鼠标放置在3D物体上，显示物体名称_unity 展示物体名字

做个记录，也方便自己以后查看，大家共同交流

 源代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
 
public class TestShow : MonoBehaviour
{
    //要显示的ui
    public RectTransform tip;
 
    // Update is called once per frame
    void Update()
    {
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        RaycastHit hit;
        bool raycast = Physics.Raycast(ray, out hit);
        if (raycast)
        {
            GameObject go = hit.collider.gameObject;
            tip.gameObject.SetActive(true);        
            tip.GetComponentInChildren<Text>().text = go.GetComponent<ObjectTips>().ObjectName;
            FollowMouse(hit .point);
        }
        else
        {
            tip.gameObject.SetActive(false);
        }
       
    }
 
    //ui位置实时变化
    void FollowMouse(Vector3 position)
    {
        Vector3 screenPoint = Camera.main.WorldToScreenPoint(position);
        tip.anchoredPosition = screenPoint +new Vector3(10f, 5f, 0);
    }
}

挂载在任意物体上，记得把tip赋值，在3D物体上加collider组件，射线才会检测到物体

using UnityEngine;
public class ObjectTips : MonoBehaviour
{
    //物体显示名称
    //挂在物体上
    public string ObjectName;
}
