Unity如何在unity中创建自定义标签系统

一、先看效果

二、代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
namespace Label
{
    
    
    public class TabGroup : MonoBehaviour
    {
    
    
        public List<TabButton> tabButtons;

        //开始的UI
        public Sprite tabIdle;
        //鼠标放到UI上的图片
        public Sprite tabHover;
        //点击显示的UI
        public Sprite tabActive;
        /// <summary>
        /// 当前在选择标签
        /// </summary>
       [HideInInspector]
        public TabButton m_SelectedTab;
        public List<GameObject> ObjectToSwap;

        /// <summary>
        /// 添加
        /// </summary>
        /// <param name="tabButton"></param>
        public void SubScribe(TabButton tabButton)
        {
    
    
            if(tabButtons==null)
            {
    
    
                tabButtons = new List<TabButton>();
            }
            tabButtons.Add(tabButton);
        }
        /// <summary>
        /// 进入
        /// </summary>
        /// <param name="tabButton"></param>
        public void OnTabEnter(TabButton tabButton)
        {
    
    
            ResetTabs();
            if(m_SelectedTab==null|| tabButton!=m_SelectedTab)
            {
    
    
                tabButton.background.sprite = tabHover;
            }

        }

        {
    
    
            if(m_SelectedTab!=null)
            {
    
    
                m_SelectedTab.Deselect();
            }

            int tabindex = tabButton.transform.GetSiblingIndex();
            //打开标签对应的面板Plane
            for (int i = 0; i < ObjectToSwap.Count; i++)
            {
    
    
                if(i==tabindex)
                {

                }else
                {
    
    
                    ObjectToSwap[i].SetActive(false);

                }
            }

        }
        /// <summary>
        /// 重置，选择完毕重置

     continue; }//要是循环到选择的跳出
                item.background.sprite = tabIdle;
            }
        }
