Dedicated Server 的 Movement 优化

如果仅仅为了性能,不希望服务端实时修正客户端坐标,以客户端发过来的坐标为准,可以开启以下选项:

[/Script/Engine.GameNetworkManager]
 MAXPOSITIONERRORSQUARED=625
 ClientAuthorativePosition=true

但是这么做会被外挂 hack

人们常常用咄咄逼人来掩饰弱点,真正持久的力量存在于忍受中,只有软骨头才急躁粗暴,他们因此丧失了人的尊严。我等待,我观看。恩惠也许来,也许不来。也许这种既平静又不平静的等待就是恩惠的使者,抑或恩惠本身。──弗兰茨·卡夫卡(Franz Kafka)
