Unity BuffSystem

1. 写好Unity的BuffSystem的单例主要接口 using UnityEngine; using System.Collections; using Police.PaoKu; using DG.Tweening; public class BuffSystem : Singleton<BuffSystem> { public BUFFType buffChoose; public Buff[] _buffSystem; public void InvokeCallBack(BUFFType _buffType , float delayTime = 0) { DOVirtual.DelayedCall(delayTime,()=> { foreach (var o in _buffSystem) { if (o.buffType == _buffType) { o.callBack.GetComponent<BaseBuff>().Begin(new string[1] { _buffType.ToString() }); break; } } }).SetUpdate(false); } public bool ReleaseBuff(BUFFType _buffType) { foreach (var o in _buffSystem) { if (o.buffType == _buffType) { o.callBack.GetComponent<BaseBuff>().Exit(); return true; } } return false; } } public enum BUFFType { 普通, 助推器, 盾, 免疫 } [System.Serializable] public class Buff { public BUFFType buffType; public GameObject callBack; }

2.写好Unity 每个Buff系统类的每一种Buff效果基础类；

using UnityEngine; using System.Collections; using System; public class BaseBuff : MonoBehaviour ,IPeriod { public float lifeTime; public float lastTime; public bool isDestroy = false; protected bool isBegin; public virtual void Begin(string[] _str) { isBegin = true; lastTime = lifeTime; } public virtual void Exit() { isBegin = false; lifeTime = lastTime; if (isDestroy) DestroyImmediate(this); } protected virtual void Update() { if(isBegin) lifeTime -= Time.deltaTime; if(lifeTime < 0) { Exit(); } } } public interface IPeriod { void Begin(string[] _str); void Exit(); }

3.然后举例写一个buff类型例子

using UnityEngine; using System.Collections; using Police.PaoKu; public class SubDefend : BaseBuff{ public override void Begin(string[] _str) { base.Begin(_str); ParkourPlayerController.Instance.Player.gameObject.AddComponent<Defend>(); } public override void Exit() { base.Exit(); Destroy(ParkourPlayerController.Instance.Player.GetComponent<Defend>()); } }

4.每个buff类型给予空物体，然后赋值给（1）的配置表

5.这样的优势是容易扩展，可以理解成工厂模式，而且改变每个buff代码互不影响。
