Unity Project Integration
At the end of this tutorial you will be able to send a message from the Client to the Server and from the Server to the client
Open your Unity Hub and create a new Project, for the sake of simplicity in this tutorial we have chosen a 2D project, however same logic will apply to 3D.

Create a new project in Unity

Choose the 2D or 3D template
Next from the
ColyseusUnity.zip
file downloaded in the previous lecture extract the Scripts
folder and import it in the Unity Project at the same level where your Asset folder is.
Import Script folder from ColyseusUnity.zip
Copy and paste the
Server
folder into the root of the project, this can be done from file explorer. Here below I am using macOS, but same logic for Windows or Linux
Added the Server into the root of the Unity Project
We have given you a simplified version of the Server files that you need for Colyseus, the bare minimum to understand how the system works. In our opinion these files will be sufficient to integrate the game and interact with the OPArcade website and use the Colyseus server, however if you want to use the full implementation these can be downloaded directly from their Github repo
Go back to your Unity Project to install the Colyseus SDK. Open Window -> Package Manager

go to Window Package Manager
Select the + icon at the top left of the Package Manager and choose the Add package from git URL option. Paste the above URL and the Colyseus SDK will be installed in the project

Colyseus SDK installed
We will need to create two new separate game objects in order to manage the scripts correctly and also a special Colyseus asset. Do not worry, the process is very simple! 🦁 You have made it this far, almost there!
- Create ServerManager and GameClient object in the scene

ServerManager and GameClient created
- Assign the
Colyseus Server Manager
script to the ServerManager object

- Assign the
Game Client
script to the GameClient object

- Create a ColiseusSettings Scriptable Object in a new Settings folder

- Assign to the ServerManager
script
both the GameClient and the newly created ColiseusSettings Scriptable Object

Now that we have created all the necessary files and steps for Unity, all we need to do is to install the files locally and check that everything is running properly 🕵️♂️
Run
npm install
into the server folder from the terminal window
Run
npm start
in the local server, if doesnt run correctly try to trash node files and reinstall
You should now see the server logging in a message to the client and the client logging in a message to the server! All done for the basic setup!
From here on you can implement more complex functions between the two
