创建 ScriptableObject

1. 在 Scripts 目录下，创建 SwordData 脚本。

   using UnityEngine;[CreateAssetMenu(fileName = "New SwordData", menuName = "Sword Data", order = 51)]
   public class SwordData : ScriptableObject
   {[SerializeField] private string swordName;[SerializeField] private string description;[SerializeField] private Sprite icon;[SerializeField] private int goldCost;[SerializeField] private int attackDamage;public string SwordName{get => swordName;set => swordName = value;}public string Description{get => description;set => description = value;}public Sprite Icon{get => icon;set => icon = value;}public int GoldCost{get => goldCost;set => goldCost = value;}public int AttackDamage{get => attackDamage;set => attackDamage = value;}
   }

CreateAssetMenu 的分级菜单的分割线是 50， 上面的 order = 51, 为二级菜单。

增加数据

1. 新建目录 Scripts - Scriptable Objects - Sword Data。在新建的目录下面，点击 Assets - Create - Sword Data 分别创建：
   
   分别点击上面7个新建的对象，在 Inspector 面板修改右边的描述属性。

使用 ScriptableObject

1. 修改 Scritps - Sword.cs 文件：

   using System;
   using UnityEngine;public class Sword : MonoBehaviour
   {[SerializeField] private SwordData swordData;private void OnMouseDown(){Debug.Log(swordData.SwordName);Debug.Log(swordData.Description);Debug.Log(swordData.Icon.name);Debug.Log(swordData.GoldCost);Debug.Log(swordData.GoldCost);Debug.Log(swordData.AttackDamage);}
   }
   

2. 为 1_Longsword 挂载脚本：
   

基于 ScriptableObjects 的事件

添加事件脚本

1. 在 Scripts 目录下新建， GameEvent.cs 和 GameEventListener.cs 脚本。
   GameEvent.cs

   using System.Collections;
   using System.Collections.Generic;
   using UnityEngine;[CreateAssetMenu(fileName = "New Game Event", menuName = "Game Event", order = 52)]
   public class GameEvent : ScriptableObject
   {private List<GameEventListener> _listeners = new List<GameEventListener>();public void Raise(){for (int i = _listeners.Count - 1; i >= 0; i--){_listeners[i].OnEventRaised();}}public void RegisterListener(GameEventListener listener){    _listeners.Add(listener);}public void UnRegisterListener(GameEventListener listener){_listeners.Remove(listener);}
   }
   

   GameEventListener.cs

   using UnityEngine;
   using UnityEngine.Events;public class GameEventListener : MonoBehaviour
   {[SerializeField] private GameEvent _gameEvent;[SerializeField] private UnityEvent response;private void OnEnable(){_gameEvent.RegisterListener(this);}private void OnDisable(){_gameEvent.UnRegisterListener(this);}public void OnEventRaised(){response.Invoke();}
   }
   

2. 点击 Assets - Create - Game Event 分别新建：
   
3. 修改 Sword.cs 脚本：
   
4. 修改 1_Longsword 的属性：
   

事件和UI

1. 在 Scripts 添加脚本 SwordMerchant.cs 脚本。

   using UnityEngine;
   using UnityEngine.UI;namespace RW.Scripts
   {public class SwordMerchant: MonoBehaviour{[SerializeField] private Text swordName;[SerializeField] private Text description;[SerializeField] private Image icon;[SerializeField] private Text goldCost;[SerializeField] private Text attackDamage;}public void UpdateDisplayUI(SwordData swordData){swordName.text = swordData.SwordName;description.text = swordData.Description;icon.sprite = swordData.Icon;goldCost.text = swordData.GoldCost.ToString();attackDamage.text = swordData.AttackDamage.ToString();}
   }
   

2. 将脚本挂载到 SwordMerchantCanvas , 并且关联上面字段和预制。
   

3. 在 SwordMerchantCanvas 上添加事件关联
   

   上面以 Longsword 为例，需要重复执行同级的6个的预制操作。

4. 运行
