Unity BuffSystem buff系统

一、介绍

现在基本做游戏都会需要些buff，之前我也在网上找也看到很多别人写的buff系统，并不是很符合我的心理预期，大部分在网上看到的都是面向过程的而不是面向对象的独立开来的buff，这样每改动一个小地方或者写一个buff基本上就要改动整个框架的部分，这对合作开发来说是比较致命的，就一个人来做的话还问题不大，但是人一单多了一人写几个buff最后就全乱了，今天把我之前写的这套框架发出来，经过验证了，原来的一个项目大概有3000多个buff，能够比较完美的支持下来。
这个buff系统架构我放到CSDN资源中，可以进入BGBuffSystem下的SampleScene查看demo。

二、buff系统架构

这里大概做一个的架构，细节后面再说。

三、架构讲解

架构这里我就简单说一下整体的逻辑，大家可以下载使用看核心。
这里我选择的面向对象也是面向组件的方式，这意味着我每一个buff都会创建两个类分别是xxxBuffCtrl操作类、xxxBuffEntity数据实体类，当buff挂载时会将对应的xxxBuffCtrl挂载到对应的对象上，而xxxBuffCtrl是负责控制buff的具体效果并且持有xxxBuffEntity数据实体，他们分别也是继承自BuffCtrlBase、BuffEntityBase。这样上层管理的时候只需要管理BuffEntityBase的初始化数据和BuffCtrlBase对应的上层管理即可。数据用的是json。

Buff层数、buff的移除方式（全部移除还是单独移除），buff多挂载，buff执行次数，buff的类型（叠加，永久，重复添加刷新时间，刷新层数）等我在上层提供了集中常用的类型，如果要想添加可以在BuffCtrlBase中写具体逻辑，在BuffEntityBase的BuffOverlap枚举中添加新类型。
这里我也提供了很多的接口具体的可以在BuffCtrlBase中看。

四、框架使用

buff数据

文中我放了三个不同类型的buff，具体的json如下图

Json数据以及工具

json如果太长看不太明白可以用在线解析工具
解析的如下图

这里我只讲几个比较关键的点，至于一眼能看懂的我就不详细说了。

ShowType

这里主要是后面接入UI准备（是否展示接口）

BuffType

这里也不需要多说，如果你要添加新的buff的话需要在这里创建一个新枚举，按照我下面创建的命名方式，创建的json文件放在下面的文件夹下（需要自行创建）

MountType

这个意思是你创建的脚本是否可以在同一个对象上挂载多个，如果你想能挂载无数个则用多挂载，如果想要单挂载跌层数则选择单挂载

BuffOverlap

这里主要是buff的叠加类型这里我创建了几个比较常用的方式，具体的逻辑是在BuffCtrlBase中的RepeatAdd方法和BuffOnStay方法

BuffShutDownType

这个参数也是为后面接入做准备留的接口，因为现在关闭其实都是有的，可以关闭多个也可以关闭一个，所以这里暂时是不需要，具体的方法都在BuffManager中。

BuffCalculateType

这里是关于buff回调执行的问题，如果是持续的buff则可以选择Loop在设置固定时间进行回调，如果只有一次（比如属性提升的buff）则可以选择Once。这里需要配合json的"m_Frequency"来使用，这里如果不为0并且 BuffCalculateType类型为Loop则相当于多少秒执行一次回调如下。

时间和层数这里也不过多说明了

"m_LimitTime": 0,
"m_TimingTime": 0,
"m_LimitLayer": 0,
"m_TimingLayer": 0,

这几个参数大概看下就明白了，具体逻辑也在BuffCtrlBase中

如何给生物添加buff

通过BuffManager来对生物添加移除buff，这里注意：需要挂载的生物是需要集成RoleAttribute的

五、总结

以上是我对网上一些面向过程的buff系统总结写出来的，如果有问题或者不明白的地方可以联系我，同事也感谢大家一直以来的支持。
