A产生命令,发给B的同时,为了增加本地的流畅度,自己预执行命令,B收到消息后,将使用同样的算法执行命令. 41 | 2. 为了克服延迟,当A发送命令之后等待一点时间,到B接收命令是,A和B同时执行命令. 42 | 43 | ### 帧同步 44 | > p2p 45 | 46 | 帧同步技术是早期RTS游戏常用的一种同步技术。与状态同步不同的是，帧同步只同步操作，其大部分游戏逻辑都在客户端上实现，服务器主要负责广播和验证操作，有着逻辑直观易实现、数据量少、可重播等优点。 47 | 48 | 客户端逻辑帧保持一致.比如A,B均从第0逻辑帧开始,在B端,如果更新逻辑到第m帧时,需要A的数据,那么此时进行行锁帧,不再继续执行逻辑,直到接受到从A发送过来的第m帧数据,处理后才继续执行第m+1帧. 49 | 50 | 优点:保证了逻辑帧的"完全同步" 51 | 缺点:锁帧等待,当某个客户端网络较差则需要等待 52 | 53 | ### 服务器同步 54 | 服务器参与,server可以用来中转消息,可以作为仲裁者.即:client产生命令,并发送给server,server校验通过后,再将命令下发给相关的client. 55 | 56 | 缺点:发起命令的client可能会存在一定的等待时机,不能及时表现,但是可以发送之后进行执行,来提高客户端的流程度,但是服务器校验不通过则刚才执行无效. 57 | 58 | 优点:可以对client的命令进行处理或者校验,然后再下发给client这样所有的client行为基本保持一致,也不会出现作弊.伤害计算,升级等关键数据应该通过这种同步策略 59 | 60 | ### 状态同步 61 | 62 | 主要同步关键的信息,如血量,等等. 63 | ### 帧同步改进版 64 | > 王者荣耀 65 | 66 | + 修改客户端,input部分和logcial部分 67 | + input部分向服务器直接发送,服务器收到之后,发给客户端逻辑层消息 68 | + 服务器切帧,服务器控制时间轴驱动 69 | 70 | ##Reference 71 | [同步算法](http://www.skywind.me/blog/archives/131) 72 | 73 | [腾讯帧同步](http://gad.qq.com/article/detail/7195472) 74
