记录一下学习联机的过程
更新一下：这个方案太麻烦了，团结的UOS做的比unity好太多，如果可以的话换团结吧，我用得很爽
先看效果：一个unity一个打包程序联机，运行起来挺流畅的这里gif帧率低
使用的是Photon的fusion的server模式
以下AI分析：
联机方案（团结引擎好像有一种后面研究一下）：
产品对比：
联机模式：
我觉得fusion的server更满足我的需求就选这个了（想要延迟低一点，响应快，竞技游戏）
先介绍一下，photon他们是自己有服务器的，他们有photon cloud和photon server（服务器模式），因为他们服务器毕竟在国外，如果国内连的话延迟会有点高，所以我想着能不能使用国内的云端服务器来降低时延（理论上是降低的，不过没试过，国内应该好一点），这个方法需要支付腾讯云服务器的费用和使用photon的费用（人数和流量），photon官方文档说了即使不使用他们的photon server也要有photon cloud 订阅（图片下面）
正好有腾讯云的cvm服务器的试用和photon的20个人以内免费，所以我就来试试了
思路：
就是把unity项目打包成一个无头模式（不用渲染画面之类的）的exe文件，放在腾讯云终端上面运行（作为服务端），然后unity和正常打包的exe就可以作为客户端连接到一个房间内，如果你按照这样做的话，后面还有两种选择，一个是云端上面运行一个exe同时存在有多个房间（一个进程多房间），或者运行多个exe，每一个房间对应一个exe（多进程多房间），各有优缺点，这个多房间我还没搞，我这里只讲如何连接上
操作：
1：host模式和server模式区别在服务端不能同时作为客户端没有写入能力，所以我们直接下载host模式的案例教程（每个正方体是一个玩家，可以发射子弹）
链接：Fusion 2 - Host Mode Overview | Photon Engine
2：把文件夹导入工程后，（先测试一下host案例模式是否能够正常运行），修改里面的BasicSpawner脚本，将里面的host换成server等（代码末尾给出）
3：点击菜单栏：工具-fusion-fusion hub,然后修改photon app setting配置
你的Appid：Your Photon Cloud | Photon Engine
4：按照官网所说，中国大陆比较特殊，需要发邮件申请（这步我不确定反正我做了，没多久就回了）
官方文档：Fusion 2 - 区域 |光子引擎 --- Fusion 2 - Regions | Photon Engine
邮件地址：hello@photonengine.com
我用网易邮箱发了个：
Based on your documents, I apply to unlock the appid for the Chinese mainland region. Are there any conditions required，This is my current appid：你的appid
然后回了两封，第一封说尽快
第二封说解锁
5：将修改好的项目，保存场景，将Game场景拖入项目设置当中打包成无头模式
6：按照腾讯云的规则把无头模式打包的所有文件拖入云端，然后控制台运行
.\NetTest.exe -batchmode -nographics -port 5055 -logFile server.log
netstat -ano | Select-String "5055"
7：成功监听端口后，在unity，点击播放的join就可以看到生成了一个预制体，如果你再运行一下正常打包程序的exe的join，又能看到一个
总结：
还是要多看官方文档，一开始没找到关于fusion和服务器对于中国大陆的限制，网络连接卡半天
好了结束了
