创建 ScriptableObject

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

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

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);}
}

为 1_Longsword 挂载脚本：

基于 ScriptableObjects 的事件

添加事件脚本

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();}
}

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

事件和UI

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();}
}
