lockstep-tutorial's Issues

Server工程打开后报错

请问这个是还需要添加什么配置吗？工程之间的引用也是丢失了的
The current .NET SDK does not support targeting .NET Core 2.2. Either target .NET Core 1.1 or lower, or use a version of the .NET SDK that supports .NET Core 2.2.

unity 版本2020.3.32 运行时报错
Assets\Scripts\Logic\EntityComponent\Component\Animator\AnimatorConfig.cs(5,30): error CS0234: The type or namespace name 'NetworkSystem' does not exist in the namespace 'UnityEngine.Networking' (are you missing an assembly reference?)
请问如何解决？

B站的视频好像失效了，看不了

关于SimulatorService.Runvidio方法中的疑问

第188行 var frameDeltaTime = (LTime.timeSinceLevelLoad - _timestampOnLastJumpToMs) * 1000，我看上下文_timestampOnLastJumpToMs表示毫秒，为什么这里还要乘以1000呢

视频无法观看

帧同步初级视频看不到

射线打aabb的判断算法有问题吧

如果tmin>1000 不是说明射线应该够不到aabb的嘛你这里没判断

请问一下大佬isClient勾选后晃动的问题

请教一下大佬，勾选isClient后，觉得不断的晃动，控制不了，这是什么原因呢？

提示这个问题是啥原因

obb 转aabb的算法有问题吧

有一个射线是从obb上方射出来的; 我obb转个180度; 那我射线不是直接转个弯就变得可以穿过obb了

输入预发送(PreSendInputCount)不就是输入延时了吗？

当前的输入，发往服务器并本地保存时，帧号是故意延后了 PreSendInputCount, 所以本地预测执行也会延后，服务收到后也会延后发送，这样不是人为的增加了输入延时了吗？仅仅是为了避免被服务器判为过期包而丢弃？
