先来看看最终效果

前言

当今大多数游戏都拥有一些形式的Buff系统，利用这种系统可以增强或削弱游戏角色的特定属性。在Unity中，我们可以使用脚本轻松地创建这样的Buff系统。

在本教程中，我们将探索如何实现一种基本的Buff系统，其中包括对游戏中的玩家或敌对角色施加各种不同类型的Buff。我们还将学习如何设置时间限制和叠加限制，以及如何实现Buff效果的应用和移除。

通过本教程，您将学习如何在Unity中创建一个完整的Buff系统，为您的游戏增加全新的深度和策略性。

开始

新增脚本PlayerController，添加玩家血量和攻击力变量，并实时显示

public class PlayerController : MonoBehaviour
{[Header("生命值")]public float HP;[Header("攻击力")]public float AD;public TextMeshProUGUI HPText;public TextMeshProUGUI ADText;private void Update(){HPText.text = $"生命值：{HP}";ADText.text = $"攻击力：{AD}";}
}

效果

绘制BUFF显示界面
状态栏

遮罩

BUFF系统

定义BUFF类型枚举

public enum BuffType
{/// <summary>/// 正面buff/// </summary>Buff,/// <summary>/// 负面buff/// </summary>Debuff,/// <summary>/// 没有buff/// </summary>None,
}

BUFF冲突方式枚举类型

/// <summary>
/// 当两个不同单位向同一个单位施加同一个buff时的冲突处理
/// </summary>
public enum ConflictResolution
{/// <summary>/// 合并为一个buff，叠层（提高等级）/// </summary>combine,/// <summary>/// 独立存在/// </summary>separate,/// <summary>/// 覆盖，后者覆盖前者/// </summary>cover,
}

新建BuffBase，Buff系统中的基类

public class BuffBase
{private GameObject m_Owner;private string m_Provider = "";private float m_MaxDuration = 3;private float m_TimeScale = 1;private int m_MaxLevel = 1;private BuffType m_BuffType = BuffType.None;private ConflictResolution m_ConflictResolution = ConflictResolution.cover;private bool m_Dispellable = true;private string m_Name = "默认名称";private string m_Description = "这个Buff没有介绍";private int m_Demotion = 1;private string m_IconPath = "";private int m_CurrentLevel = 0;private float m_ResidualDuration = 3;private bool m_Initialized = false;/// <summary>/// 此buff的持有者/// </summary>public GameObject Owner{get { return m_Owner; }protected set { m_Owner = value; }}/// <summary>/// 此Buff的提供者/// </summary>public string Provider{get { return m_Provider; }protected set { m_Provider = value; }}/// <summary>/// Buff的初始持续时间/// </summary>public float MaxDuration{get { return m_MaxDuration; }protected set { m_MaxDuration = Math.Clamp(value, 0, float.MaxValue); }}/// <summary>/// buff的时间流失速度，最小为0，最大为10。/// </summary>public float TimeScale{get { return m_TimeScale; }set { m_TimeScale = Math.Clamp(value, 0, 10); }}/// <summary>/// buff的最大堆叠层数，最小为1，最大为2147483647/// </summary>public int MaxLevel{get { return m_MaxLevel; }protected set { m_MaxLevel = Math.Clamp(value, 1, int.MaxValue); }}/// <summary>/// Buff的类型，分为正面、负面、中立三种/// </summary>public BuffType BuffType{get { return m_BuffType; }protected set { m_BuffType = value; }}/// <summary>/// 当两个不同单位向同一个单位施加同一个buff时的冲突处理/// 分为三种：/// combine,合并为一个buff，叠层（提高等级）///  separate,独立存在///   cover, 覆盖，后者覆盖前者/// </summary>public ConflictResolution ConflictResolution{get { return m_ConflictResolution; }protected set { m_ConflictResolution = value; }}/// <summary>/// 可否被驱散/// </summary>public bool Dispellable{get { return m_Dispellable; }protected set { m_Dispellable = value; }}/// <summary>/// Buff对外显示的名称/// </summary>public string Name{get { return m_Name; }protected set { m_Name = value; }}/// <summary>/// Buff的介绍文本/// </summary>public string Description{get { return m_Description; }protected set { m_Description = value; }}/// <summary>/// 图标资源的路径/// </summary>public string IconPath{get { return m_IconPath; }protected set { m_IconPath = value; }}/// <summary>/// 每次Buff持续时间结束时降低的等级，一般降低1级或者降低为0级。/// </summary>public int Demotion{get { return m_Demotion; }protected set { m_Demotion = Math.Clamp(value, 0, MaxLevel); }}/// <summary>/// Buff的当前等级/// </summary>public int CurrentLevel{get { return m_CurrentLevel; }set{//计算出改变值int change = Math.Clamp(value, 0, MaxLevel) - m_CurrentLevel;OnLevelChange(change);m_CurrentLevel += change;}}/// <summary>/// Buff的当前剩余时间/// </summary>public float ResidualDuration{get { return m_ResidualDuration; }set { m_ResidualDuration = Math.Clamp(value, 0, float.MaxValue); }}/// <summary>/// 当Owner获得此buff时触发/// 由BuffManager在合适的时候调用/// </summary>public virtual void OnGet() { }/// <summary>/// 当Owner失去此buff时触发/// 由BuffManager在合适的时候调用/// </summary>public virtual void OnLost() { }/// <summary>/// Update,由BuffManager每物理帧调用/// </summary>public virtual void FixedUpdate() { }/// <summary>/// 当等级改变时调用/// </summary>/// <param name="change">改变了多少级</param>protected virtual void OnLevelChange(int change) { }/// <summary>/// 初始化/// </summary>/// <param name="owner"></param>/// <param name="provider"></param>/// <exception cref="Exception"></exception>public virtual void Initialize(GameObject owner, string provider){if (m_Initialized){throw new Exception("不能对已经初始化的buff再次初始化");}if (owner == null || provider == null){throw new Exception("初始化值不能为空");}Owner = owner;Provider = provider;m_Initialized = true;}
}

新建ShowBuff，控制BUFF的显示

public class ShowBuff : MonoBehaviour
{[SerializeField, Header("Buff项预制体")]private GameObject m_BuffItemTemplate;[SerializeField, Header("对象池")]private GameObject m_Pool;[SerializeField, Header("Buff项父物体")]private GameObject m_Buffs;[SerializeField, Header("与Buff相关联的游戏对象")]private PlayerController m_Hero;private ObjectPool<UI_BuffItem> m_BuffItemPool;// Buff项对象池// Buff项对象池的创建函数，用于实例化Buff项private UI_BuffItem Pool_CreateFunc(){return Instantiate(m_BuffItemTemplate, this.transform).GetComponent<UI_BuffItem>();}// Buff项对象池的获取时回调，用于激活对象并设置父物体private void Pool_ActionOnGet(UI_BuffItem UI_BuffItem){UI_BuffItem.gameObject.SetActive(true);UI_BuffItem.transform.SetParent(m_Buffs.transform);}// Buff项对象池的回收时回调，用于隐藏对象并设置父物体private void Pool_ActionOnRelease(UI_BuffItem UI_BuffItem){UI_BuffItem.gameObject.SetActive(false);UI_BuffItem.transform.SetParent(m_Pool.transform);}// Buff项对象池的销毁时回调，用于销毁对象private void Pool_ActionOnDestroy(UI_BuffItem UI_BuffItem){Destroy(UI_BuffItem.gameObject);}// Buff监听器，当有新的Buff时调用ShowBuffCore方法private void BuffListener(BuffBase newBuff){ShowBuffCore(newBuff);}private void ShowBuffCore(BuffBase buff){m_BuffItemPool.Get().Initialize(buff, m_BuffItemPool);}private void Awake(){m_BuffItemPool = new ObjectPool<UI_BuffItem>(Pool_CreateFunc,Pool_ActionOnGet,Pool_ActionOnRelease,Pool_ActionOnDestroy,true,100,10000);// 遍历BuffManager中与m_Hero关联的所有Buff，并调用ShowBuffCore方法显示它们foreach (BuffBase item in BuffManager.Instance.StartObserving(m_Hero.gameObject, BuffListener)){ShowBuffCore(item);}}}

挂载脚本并配置参数

新增UI_BuffItem，控制Buff信息UI显示

public class UI_BuffItem : MonoBehaviour
{[SerializeField, Header("遮罩层")]private Image m_Mask_M;[SerializeField, Header("等级文本")]private TextMeshProUGUI m_Level;[SerializeField, Header("边框")]private Image m_Frame;[SerializeField, Header("图标")]private Image m_Icon;[Space][Header("Buff详情")][SerializeField, Header("详情弹窗")]private GameObject m_BuffInfo;[SerializeField, Header("Buff名称文本")]private TextMeshProUGUI m_BuffName;[SerializeField, Header("Buff描述文本")]private TextMeshProUGUI m_Description;[SerializeField, Header("Buff来源文本")]private TextMeshProUGUI m_Provider;private ObjectPool<UI_BuffItem> m_RecyclePool;private bool m_Initialized = false;// 是否已经初始化private bool m_NeedNumber = false;// 是否需要显示等级private bool m_NeedLine = false;// 是否需要显示计时工具private BuffBase m_TargetBuff;public void OnPointerEnter(){m_BuffInfo.gameObject.SetActive(true);ShowInfo(m_TargetBuff);}// 显示Buff详细信息public void ShowInfo(BuffBase buff){m_BuffName.text = buff.Name;m_Description.text = buff.Description;m_Provider.text = "来自：" + buff.Provider;}public void OnPointerExit(){m_BuffInfo.gameObject.SetActive(false);}public void Initialize(BuffBase buff, ObjectPool<UI_BuffItem> recyclePool){m_Icon.sprite = Resources.Load<Sprite>(buff.IconPath);m_TargetBuff = buff;m_RecyclePool = recyclePool;if (m_TargetBuff.MaxLevel > 1){m_NeedNumber = true;m_Level.gameObject.SetActive(true);}else{m_NeedNumber = false;m_Level.gameObject.SetActive(false);}if (m_TargetBuff.TimeScale > 0){m_NeedLine = true;m_Mask_M.gameObject.SetActive(true);}else{m_NeedLine = false;m_Mask_M.gameObject.SetActive(false);}switch (buff.BuffType){case BuffType.Buff:m_Frame.color = Color.green;break;case BuffType.Debuff:m_Frame.color = Color.red;break;case BuffType.None:m_Frame.color = Color.white;break;default:break;}m_Initialized = true;}private void Update(){if (m_Initialized){//需要显示计时工具才显示if (m_NeedLine){m_Mask_M.fillAmount = 1 - (m_TargetBuff.ResidualDuration / m_TargetBuff.MaxDuration);}//需要显示等级才显示if (m_NeedNumber){m_Level.text = m_TargetBuff.CurrentLevel.ToString();}//如果当前等级等于零说明他已经被废弃了，所以就可以回收了if (m_TargetBuff.CurrentLevel == 0 ){m_RecyclePool.Release(this);}}}
}

绑定脚本，配置参数并添加鼠标移入移出事件

}

加几个BUFF测试

1. 逐层消失，升级不重置剩余时间的BUFF

public class Buff001 : BuffBase
{// Buff每秒钟恢复的生命值private float m_HealingPerSecond = 20f;// 作用目标，即被添加Buff的角色private PlayerController playerController;// 初始化Buff的属性和状态public override void Initialize(GameObject owner, string provider){base.Initialize(owner, provider);// 获取作用目标的PlayerController组件playerController = owner.GetComponent<PlayerController>();// 设置Buff的基本属性MaxDuration = 15; // 最大持续时间为15秒TimeScale = 1f;   // 时间流失速度为正常值MaxLevel = 5;     // 最大等级为5级BuffType = BuffType.Buff; // Buff类型为增益效果ConflictResolution = ConflictResolution.combine; // Buff冲突时采用合并方式Dispellable = false; // 不可被驱散Name = "生命值";   // Buff的名称Description = $"每秒恢复{m_HealingPerSecond}点生命值"; // Buff的描述Demotion = 1; // 每次Buff持续时间结束时降低的等级IconPath = "Icon/2003"; // Buff的图标路径}// 在固定时间间隔内更新Buff的效果public override void FixedUpdate(){// 每秒钟恢复指定的生命值playerController.HP += m_HealingPerSecond * BuffManager.FixedDeltaTime;}
}

调用测试

public class Test : MonoBehaviour
{public PlayerController playerController;void Update(){if (Input.GetKeyDown(KeyCode.Alpha1)){//作用目标 来源：自己，每次加1层BuffManager.Instance.AddBuff<Buff001>(playerController.gameObject, "自己", 1);}}
}

效果

2. 一次性全部消失，升级重置剩余时间的BUFF

public class Buff002 : BuffBase
{// 攻击力增加的数值private float m_ADUp = 10f;private PlayerController playerController;public override void Initialize(GameObject owner, string provider){base.Initialize(owner, provider);MaxDuration = 5f;// 最大持续时间为5秒MaxLevel = 10;// 最大等级为10级BuffType = BuffType.Buff;// Buff类型为增益效果ConflictResolution = ConflictResolution.combine;// Buff冲突时采用合并方式Dispellable = false;// 不可被驱散Name = "借来的短剑";// Buff的名称Description = "每层增加10点攻击力";// Buff的描述IconPath = "Icon/1036";// Buff的图标路径Demotion = MaxLevel;// 每次Buff持续时间结束时降低的等级playerController = Owner.GetComponent<PlayerController>();}//当等级改变时调用protected override void OnLevelChange(int change){// 根据变化的等级调整角色的攻击力playerController.AD += m_ADUp * change;//每次升级，重置Buff的当前剩余时间ResidualDuration = MaxDuration;}
}

调用

BuffManager.Instance.AddBuff<Buff002>(playerController.gameObject, "自己", 1);

效果

3. 永久BUFF，类似被动BUFF

public class Buff003 : BuffBase
{PlayerController playerController;public override void Initialize(GameObject owner, string provider){base.Initialize(owner, provider);TimeScale = 0f;// 时间缩放为0，暂停游戏中的时间流逝MaxLevel = int.MaxValue;// 最大等级设置为int的最大值，表示无限等级BuffType = BuffType.Buff;// Buff类型为增益效果ConflictResolution = ConflictResolution.separate;// Buff冲突时采用分离方式Dispellable = false;// 不可被驱散Name = "盛宴";Description = "增加生命值";IconPath = "Icon/Feast";Demotion = 0;// 每次Buff持续时间结束时降低的等级playerController = owner.GetComponent<PlayerController>();}// 当Buff等级发生变化时触发protected override void OnLevelChange(int change){// 根据变化的等级调整角色的生命值playerController.HP += change;}
}

调用

BuffManager.Instance.AddBuff<Buff003>(playerController.gameObject, "自己", 80);

效果

4. 负面BUFF，根据当前BUFF等级计算每秒收到伤害值，当两个不同单位向同一个单位施加同一个buff时BUFF独立存在

public class Buff004 : BuffBase
{PlayerController playerController;// 每秒受到的伤害值float m_DamagePerSeconds = 30;public override void Initialize(GameObject owner, string provider){base.Initialize(owner, provider);playerController = owner.GetComponent<PlayerController>();MaxDuration = 5f;// Buff的最大持续时间为5秒TimeScale = 1f;// 时间缩放为1，正常流逝时间MaxLevel = 5;// 最大等级设置为5BuffType = BuffType.Debuff;// Buff类型为减益效果ConflictResolution = ConflictResolution.separate;// Buff冲突时采用分离方式Dispellable = true;// 可以被驱散Name = "流血";Description = "每层每秒受到30点伤害";IconPath = "Icon/Darius_PassiveBuff";Demotion = MaxLevel;// 每次Buff持续时间结束时降低的等级}// 当Buff等级发生变化时触发protected override void OnLevelChange(int change){//每次升级，重置Buff的当前剩余时间ResidualDuration = MaxDuration;}public override void FixedUpdate(){// 根据当前等级、每秒伤害值和固定时间步长来计算角色受到的伤害playerController.HP -= m_DamagePerSeconds * CurrentLevel * BuffManager.FixedDeltaTime;}
}

调用

if (Input.GetKeyDown(KeyCode.Alpha4))
{BuffManager.Instance.AddBuff<Buff004>(playerController.gameObject, "敌人1", 1);
}
if (Input.GetKeyDown(KeyCode.Alpha5))
{BuffManager.Instance.AddBuff<Buff004>(playerController.gameObject, "敌人2", 1);
}

效果

5. 一级叠加两层，后面都叠加一层

public class Buff005 : BuffBase
{PlayerController playerController;// 每秒受到的伤害值float m_DamagePerSeconds = 10;public override void Initialize(GameObject owner, string provider){base.Initialize(owner, provider);playerController = owner.GetComponent<PlayerController>();MaxDuration = 1f;// Buff的最大持续时间为1秒TimeScale = 1f;// 时间缩放为1，正常流逝时间MaxLevel = int.MaxValue;// 最大等级设置为int.MaxValue，即无限大BuffType = BuffType.Debuff;// Buff类型为减益效果ConflictResolution = ConflictResolution.combine;// Buff冲突时采用合并方式Dispellable = true;// 可以被驱散Name = "被点燃";Description = "每秒受到10点伤害,首次受到该BUFF伤害,一次叠加2层,后续叠加1层";IconPath = "Icon/Darius_PassiveBuff";Demotion = 1;// 每次Buff持续时间结束时降低的等级}public override void FixedUpdate(){// 根据每秒伤害值和固定时间步长来计算角色受到的伤害playerController.HP -= m_DamagePerSeconds * BuffManager.FixedDeltaTime;}
}

调用

if (Input.GetKeyDown(KeyCode.Alpha6))
{int number = 1;//获取叠加的BUff层数if(BuffManager.Instance.FindBuff<Buff005>(playerController.gameObject).Count == 0  ){number = 2;}BuffManager.Instance.AddBuff<Buff005>(playerController.gameObject, "敌人1", number);
}
