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
最终效果
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

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)

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5
BuffType = 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);
}
效果
最终效果
