#if UNITY_EDITOR//仅在编辑器中生效
[CustomEditor(typeof(Inventory))]
public class InventoryEditor : Editor
{
    public override void OnInspectorGUI()
    {
        //获取当前选择对象实例
        Inventory inventory = target as Inventory;
        //创建并判断如果按下生成按键
        if (GUILayout.Button("生成"))
        {
            //获取原有格子数量
            var chileNum = Selection.activeTransform.childCount;
            //清空原有的格子
            for (int i = 0; i < chileNum; i++)
            {
                DestroyImmediate( Selection.activeTransform.GetChild(0).gameObject);
            }
            //根据新数量生成格子，并使格子作为子级
            for (int i = 0; i < inventory.slotNum; i++)
            {
                GameObject go = Instantiate(inventory.slotPrefab, Selection.activeTransform);
            }
        }
        base.OnInspectorGUI();//原有的UI界面
    }
}
#endif

然后将脚本挂载到panel上，同时增加网格布局组件（用来自定义格子的上下左右间距）调试排列时可以通过写好格子初始数量，点击生成来查看生成格子后的排列

在这里插入图片描述

2.3 点击显示详细信息

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;
public class SetDetail : MonoBehaviour
{
    public Text title;
    public Text word;
    public string names = "";
    public string introduce = "";

    public void fillin()
    {
        title.text = names;
        word.text = introduce;
    }
 
}

挂载到按钮上，同时设置点击事件

在这里插入图片描述

其中Title等值在上一个脚本中赋值

slotPrefab.GetComponentInChildren<SetDetail>();
scrip.title = first;
scrip.word = second;
scrip.names = item.Value.Name;
scrip.introduce = item.Value.Detail;
