What you'll learn

  • Server and client connection with LiteNetLib
  • Send and receive data with LiteNetLib
  • Process received data

Course content

1 section • 9 lectures • 1h 11m total length

  • Intro0:37

    This is the LiteNetLib , grad the Source Code (.zip) of the Latest Release
    https://github.com/RevenantX/LiteNetLib/releases

    You will also need to install .NET core package in Visual Studio Installer.


    The projects are attached here.



  • Needed Tools and Libraries0:31

    Download the LiteNetLib source code and install it with the Visual Studio Installer, then modify the .Net Core workload to build and run .Net Core projects.

  • Setting up the Projects (Client and Server)3:32

    Create a unique 2D Unity project for the client and server. Copy and paste folders, import assets and sprites, and configure the necessary scripts for the LiteNetLib networking setup.

  • Creating a simple play scene with player movement4:02

    Create a simple play scene in Unity and implement a player movement script to enable horizontal movement, setting up the scene with prefabs.

  • First Networking Script on Client5:31

    Write the client networking script to connect to the server, implement the required functions, initialize data, and save the scene before moving on to the server setup.

  • Networking Script for Server and first connection of client and server6:55

    Develop and test a server script and the first client connection in a Unity LiteNetLib and .NET Core multiplayer setup, including start, event polling, and shutdown.

  • Sending and Receiving Player positions27:55

    Explore sending and receiving player positions in a Unity LiteNetLib setup by building a 12-byte position packet, transmitting x and y floats to the server, and updating a positions dictionary.

  • Adding network players on screen and moving them9:39

    Create and move network players on screen by wiring scripts and namespaces in Unity, using LiteNetLib multiplayer with a .NET Core server.

  • Additional stuff : More efficient code (network)12:45

    Improve network efficiency in Unity LiteNetLib multiplayer basics by sending data only when movement occurs, and optimize data handling with checks and dictionaries for reliable position updates.

Requirements

  • Basic usage of Unity
  • Visual Studio
  • .NET Core Package in Visual Studio Installer
  • LiteNetLib Release Source Code

Description

This all may sound hard and difficult but its rather easy once you know how it works.

Just follow me along on this journey to write a basic multiplayer game!

We will write a server that will be a seperate .NET core application which is also using C# , and we will use the same UDP library as for Unity.

The server runs independently from any Unity programs.

Our client will be written in Unity and C# and will contain the player stuff.

Both will be using the same library "LiteNetLib" which is a very competent library for UDP (and also Reliable UDP)


At the end we will have a way to send and receive data and we will be able to join the server with our game clients and see each client on the game and move around and see the movements.

Who this course is for:

  • Game Devs who want to try out networking (UDP)
  • People who want to use LiteNetLib in Unity and .NET Core
  • Is suitable for beginner to intermediate level programmers who want to make an online game.
