Simply realize the same interface and click different buttons to display the corresponding UI panel

Tip: The following is the text of this article, and the following cases are for reference

1. Create a new C# code called UIManager

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class UIManager : MonoBehaviour
{
    
    
    //公开定义三个GameObject类用来表示三个UI界面
    public GameObject UIModel;
    public GameObject UIMaterial;
    public GameObject UIMapping;
    void Start()
    {
    
    
        Status = UIStatus.Model;//在start方法中给属性赋值Model，让游戏一开始就显示Model模型界面
    }

    public enum UIStatus//定义枚举，列举UI显示的三种情况
    {
    
    
        Model,
        Material,
        Mapping
    }
    private UIStatus uistatus;//创建枚举变量
    private UIStatus Status//定义属性给枚举变量赋值
    {
    
    
        get
        {
    
    
            return uistatus;
        }
        set
        {
    
    
            uistatus = value;
            UpdateUI();//在给枚举变量赋值后调用UI显示方法，控制UI的显示
        }

    }
    public void UpdateUI()//定义UI显示的方法，通过枚举变量的值来判断
    {
    
    
        UIModel.SetActive(uistatus == UIStatus.Model);
        UIMaterial.SetActive(uistatus == UIStatus.Material);
        UIMapping.SetActive(uistatus == UIStatus.Mapping);
    }
    public void Model()//显示Model模型界面的方法
    {
    
    
        Status = UIStatus.Model;//给属性Status赋值，赋值的同时调用了UpdateUI方法
    }
    public void Material()//显示Material材质界面的方法
    {
    
    
        Status = UIStatus.Material;
    }
    public void Mapping()//显示Mapping贴图界面的方法
    {
    
    
        Status = UIStatus.Mapping;
    }
}

2. Create a new Panel in the scene (name it Panel1)

Create a new one under Panel1 : ① a Panel (named Panel2 ), ② three Scroll Views (named Model Interface , Material Interface , Mapping Interface respectively ) and delete the Scrollbar Horizontal inside (you can also not delete it); create a new three under Panel2 Button (named Model , Material , Model respectively )
