1. Add repo:

sudo sh -c 'echo "deb https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'

2. Add public key:

wget -qO - https://hub.unity3d.com/linux/keys/public | sudo apt-key add -

3. Update and install Unity:

sudo apt update
sudo apt-get install unityhub

4. Install Unity extension to VS (will install C# extensions as well)

5. Download .NET SDK install script:

wget https://dot.net/v1/dotnet-install.sh -O dotnet-install.sh

6. Change the script permission:

chmod +x ./dotnet-install.sh

7. Install .NET SDK:

./dotnet-install.sh --channel 7.0

8. Add .NET path to bashrc file:

# DOTNET path
export DOTNET_ROOT=$HOME/.dotnet
export PATH=$PATH:$DOTNET_ROOT:$DOTNET_ROOT/tools

9. To ensure .NET is correctly installed and that VS-Code can see it, reboot your machine and then open VS-Code

10. Inside VS-Code open the terminal, then open a folder with, create and run a C# code file (F5 ou Fn+F5). In the output tab you should see the following:

Using dotnet configured on PATH
Dotnet path: /home/fornav/.dotnet/dotnet
Activating C# standalone...

[stdout] {"pipeName":"/tmp/b8b43f34-fcd1-4eb3-92ea-c60d614a8799.sock"}

Installing mono (if you want):

sudo apt install gnupg ca-certificates

sudo apt-key adv –keyserver hkp://keyserver.ubuntu.com:80 –recv-keys 3FA7E0328081BFF6A14DA29AA6A19B38D3D831EF

echo deb https://download.mono-project.com/repo/ubuntu stable-focal main | sudo tee /etc/apt/sources.list.d/mono-official-stable.list

sudo apt update

sudo apt install mono-complete

To use mono to compile and run C#, we will need to do some stuff:

1. Allow .cs file to be executable:

sudo chmod +x code_file.cs

2. To compile into .exe:

mcs -out:code_file.exe code_file.cs

3. To run it:

mono code_file.exe

The recommended way to run C# code will be via C# Dev Kit inside VS-Code or inside Unity while running a project.

This repo

This repository contains my personal studies about C# and Unity game development. I have divided every exercise and Unity project in two folders each: public and private. Private folders wont be pushed to this public repository (see .gitignore).
