下面来介绍代码。

物品基类。

这个类是所有物品的基类，里面定义了一些属性，这些属性是所有物品都共有的，所有
把他们抽象出来，里面还有2个构造方法、2个结构体和一个显示提示信息的方法。using UnityEngine;
using System.Collections;/// <summary>
/// 物品基类

public class Item  {public int ID { get; set; }public string Name { get; set; }public ItemType Type { get; set; }public ItemQuality Quality { get; set; }public string Description { get; set; }public int Capacity { get; set; }public int BuyPrice { get; set; }public int SellPrice { get; set; }public string Sprite { get; set; }public Item(){this.ID = -1;}public Item(int id, string name, ItemType type, ItemQuality quality, string des, int capacity, int buyPrice, int sellPrice,string sprite){this.ID = id;this.Name = name;this.Type = type;this.Quality = quality;this.Description = des;this.Capacity = capacity;this.BuyPrice = buyPrice;this.SellPrice = sellPrice;this.Sprite = sprite;}/// <summary>/// 物品类型/// </summary>public enum ItemType{Consumable,//消耗品Equipment,//装备Weapon,//武器Material//材料}/// <summary>/// 品质/// </summary>public enum ItemQuality{Common,//一般Uncommon,//非一般Rare,//稀有的Epic,//史诗Legendary,//传说Artifact//人造物品}/// <summary> /// 得到提示面板应该显示什么样的内容/// </summary>/// <returns></returns>public virtual string GetToolTipText(){string color = "";switch (Quality){case ItemQuality.Common:color = "white";break;case ItemQuality.Uncommon:color = "lime";break;case ItemQuality.Rare:color = "navy";break;case ItemQuality.Epic:color = "magenta";break;case ItemQuality.Legendary:color = "orange";break;case ItemQuality.Artifact:color = "red";break;}string text = string.Format("<color={4}>{0}</color>\n<size=10><color=green>购买价格：{1} 出售价格：{2}</color></size>\n<color=yellow><size=10>{3}</size></color>", Name, BuyPrice, SellPrice, Description, color);return text;}
}

下面是消耗品类，继承物品基类。

using UnityEngine;
using System.Collections;
/// <summary>
/// 消耗品类

public class Consumable : Item {public int HP { get; set; }public int MP { get; set; }public Consumable(int id, string name, ItemType type, ItemQuality quality, string des, int capacity, int buyPrice, int sellPrice ,string sprite,int hp,int mp):base(id,name,type,quality,des,capacity,buyPrice,sellPrice,sprite){this.HP = hp;this.MP = mp;}public override string GetToolTipText(){string text = base.GetToolTipText();string newText = string.Format("{0}\n\n<color=blue>加血：{1}\n加蓝：{2}</color>", text, HP, MP);return newText;}public override string ToString(){string s = "";s += ID.ToString();s += Type;s += Quality;s += Description;s += Capacity; s += BuyPrice;s += SellPrice;s += Sprite;s += HP;s += MP;return s;}}

下面是装备类，继承物品基类。

}

下面是武器类，继承物品基类。

using UnityEngine;

}

下面是材料类，继承物品基类。
