Unity .Net Core Networking Client

Lightweight Unity client for NetCoreServer

This is an example for a unity client that works with a NetCoreServer server application. The latest version is built with Unity 2020.3.1f1 and NetCoreServer 5.0.15.

Features

• Supports SSL, TCP & UDP
• Client code from NetCoreServer with wrappers for unity usage
• Precompiled server executables for windows for easy testing
• Small GC overhead - Usage of MemoryStream
• Async send and receive - Does not block the Main Thread
• Low level - just plain UPD/TCP/SSL
• Tested with local, network and remote server

Installation

You can either install the package through the package manager with OpenUPM (Recommended) or download the scripts as a unity package

OpenUPM

# Install openupm-cli
$ npm install -g openupm-cli

# Enter your unity project folder
$ cd YOUR_UNITY_PROJECT_FOLDER

# Add package to your project
$ openupm openupm add com.deml.netcore-networking

Latest Unity Package

Setup

• Unity 2020.3.1f1 (Works with older versions as well)
• Precompiled servers an in ServerWindows, run the bat you want to test
• Open Samples/EchoClient/Scenes/NetworkExampleClient.unity and hit play.
• Default port is 3333 when running the bat files.

Troubleshooting

• I can't find the samples
  • The samples are stored in Assets/NetCoreNetworking/Samples~. A symlink at Assets/Samples points to the folder. That symlink might break when pulling for the first time on Windows. There are two solutions for it:
    • Just run Assets/.RelinkSamples.bat to regenerate the symlink.
    • Configure your git to support symlinks
• The precompiled server scripts don't work
  • Install Dotnet from https://dotnet.microsoft.com/download

TODO

• Split messages back into the sent chunks
• Fix bug: Repeated asnyc sending results in some packages not being sent for UDP
• Support Websockets
