What is Dedicated Server?

Dedicated Server is a type of web hosting service that is provided exclusively to a customer. It is on 24 hours a day in the data center and is connecting to the World Wide Web. Also, it is a piece of computer hardware that is used exclusively to host websites, data, and applications. When a user uses a dedicated server, all resources such as memory, RAM, and CPU are completely on their own and they do not share them with other users. As servers should be available for a very long time and hardware stability is important, special technology is using to extend the life of server components.

Dedicated Server Usage Cases

1–> Used for an email server, database server, process server and etc.

2–> Used in various technical disciplines of engineering, medicine and etc.

3–> Used to store information

4–> Hosting websites

5–> Control, management, and evaluation of computer networks

What is Unity?

Unity is a cross-platform 2D/3D game engine and a powerful IDE for developers that is used primarily to develop video games and emulators for computers, consoles, mobile devices, and more. It can provide many of the most important internal features that make the game work. This game engine has a powerful visual interface for game building, platform development, and an active community.

Apple Developers Conference first introduced Unity in June 2005 as the unique Mac OS X game engine and was developed by the Unity Technologies team. It has since been gradually developing to support a variety of desktop, mobile, console and virtual reality operating systems.

Requirements

In this section, we are going to explain making Dedicated Server for Multiplayer Game on Unity. A simple build script that you should setup and it has four different methods is:

BuildAll()  {  BuildWindowsServer();  BuildLinuxServer();  BuildWindowsClient();  }

You don’t need to go to the build settings and select a bunch of options each time to build your project, you can use the scripted method that will do everything for you.

The following script only executes the build-all method in that build script.

echo "Starting build..."  "c:\Program Files\Unity\Hub\Editor\2022.5.23f1\Editor\Unity.exe" -quit -batchmode -projectPath "C:\Users\Neil\Dev\shrinewars" -executeMethod BuildScript.BuildAll  echo "Finished build!"

The end result of all this will be three different builds, one for the Windows Server, one for the Linux Server, and one for the Windows Client. To do this, you should deploy a Linux server. You need to buy a Dedicated Server for Multiplayer on Unity. In the next section, we will teach you how to buy a Dedicated Server for Multiplayer.

In this section, navigate to the Unity project. If you setup the editor script, you will see the Build option at the top.

Now click on the Build Server (Linux) in the Build section. Then it will start automatically building everything. After the build is complete, if you go back to vs code you can see the builds folder.

You should open the folder in the file explorer. To do this double click on the Builds folder and select Reveal in File explorer:

To upload, you can use 7-zip and compress it to a zip file. Select 7-Zip and then click Add to “Server.zip”:

If you click on it, Eldernode will give you a public IP and a username. You can use them to connect using SSH Client. To do this copy IP in your Terminal.

Then run the following command to connect to this server:

ssh -i ~/Downloads/sshkeypair.pem [email protected]

You will be asked if you want to continue connecting, press yes.

In this section, you should upload your build zip file. To do this enter the following command:

scp -i ~Downloads/sshkeypair.pem Builds/Linux/Server.zip [email protected]:.

Note: Remember to replace your IP address.

The colon and dot indicate where you want to place this zip file on your Linux server. Here it is placed right at the root.

If you want to go back to your terminal use the following command:

ls   server.zip

You can unzip the uploaded file with the following command:

unzip Server.zip

To check what’s there just type the following command:

ls   Server.zip

To go into the server folder just run the following command:

cd Server/

Now you should see the server.x86_64 is what you will be running as the server.

In this step, go back to the Management Console and configure your instance firewall to allow traffic from only one or two ports 777. To do this go to the Networking section and click on Add role.

Note that if you use a telepathy transmission that uses TCP, you should add only one role and specifies the protocol and port to open as below. That’s it! You have setup a Firewall.

Now go back to the Linux Server terminal. Then you should run the server by entering the following command:

./Server.x86_64

You should make it executable. To do this type the following:

chmod +x ./Server.x86_64

Remember that try the above command again to run it.

In the output, you can see Unity is initializing everything and also the telepathy transports initialized the server started and it is listening on port 7777.

Now navigate to Unity and hit play. To join the server as a client, you have to paste the IP in the localhost section and click on Client.

 

Join-server-as-client

 

You can see that you are connected to the server and move around if the client is ready. Then, click Client Ready.

 

Connect-successfully-to-server

 

Next, we will try this with multiple clients. To do this, use ParrelSync and hit Clones Manager. After the Clones Manager window opens, click Open in New Editor.

 

Clones-Manager

 

After the new editor opens, hit play on both and paste the IP. Then click on the Client and Client Ready. Now you have two clients connected to a server on the cloud.

If you were just running only on localhost,  there would be a noticeable delay.

You can do this with many tweaks such as using UDP instead of TCP and not using the default network transform.
