What is a WebSocket?

A WebSocket is a protocol that allows for real-time communication between a client and a server. It is a two-way communication protocol that is used for web applications that require real-time data updates, such as chat applications, online gaming, and stock market updates. With a WebSocket, you can establish a persistent connection between a client and a server, allowing for data to be transmitted in real-time without the need for constant HTTP requests.

What is Godot WebSocket?

The Godot WebSocket is a built-in module in the Godot game engine that allows you to establish a WebSocket connection between your game and a server. It is a simple API that allows you to send and receive data in real-time, making it ideal for online multiplayer games, chat applications, and other real-time applications.

How to use Godot WebSocket?

Using the Godot WebSocket is simple and straightforward. Here are the steps you need to follow:

Enable the WebSocket module in your project settings.
Create a WebSocket client object in your game.
Connect to the server using the WebSocket client object.
Send and receive data in real-time using the WebSocket client object.

Enabling the WebSocket module in your project settings

In order to use the Godot WebSocket, you need to enable the WebSocket module in your project settings. To do this, follow these steps:

Open your Godot project.
Click on the Project Settings button in the top-right corner of the editor.
Select the Plugins tab.
Check the box next to the WebSocket plugin to enable it.
Click the Save button to save your changes.

Creating a WebSocket client object in your game

Once you have enabled the WebSocket module in your project settings, you can create a WebSocket client object in your game. To do this, follow these steps:

Create a new script in your game.
Add the following code to create a new WebSocket client object:

var ws = WebSocketClient.new()

Connecting to the server using the WebSocket client object

After you have created the WebSocket client object, you can connect to the server using the connect_to_url method. To do this, follow these steps:

Add the following code to connect to the server:

ws.connect_to_url(url)

Replace url with the URL of the server you want to connect to.

Sending and receiving data in real-time using the WebSocket client object

Once you have connected to the server, you can send and receive data in real-time using the WebSocket client object. To do this, follow these steps:

Add the following code to send data to the server:

ws.write_message(message)

Replace message with the data you want to send to the server.

Add the following code to receive data from the server:

var message = ws.get_peer(1).get_packet()

The get_peer method returns the peer object for the specified index. In this case, we are getting the peer object for index 1, which is the server. The get_packet method returns the next packet from the peer object, which contains the data received from the server.

Examples of using Godot WebSocket

Here are some examples of how you can use the Godot WebSocket in your game:

Online multiplayer game

You can use the Godot WebSocket to create an online multiplayer game where players can connect to a server and play against each other in real-time. The WebSocket allows for real-time communication between the players and the server, making gameplay smooth and seamless.

Chat application

You can use the Godot WebSocket to create a chat application where users can send and receive messages in real-time. The WebSocket allows for real-time communication between the users and the server, making the chat application fast and responsive.

Real-time data dashboard

You can use the Godot WebSocket to create a real-time data dashboard where data is updated in real-time as it is received from the server. The WebSocket allows for real-time communication between the dashboard and the server, making the data updates fast and accurate.

Benefits of using Godot WebSocket

Here are some of the benefits of using the Godot WebSocket:

Real-time communication

The Godot WebSocket allows for real-time communication between the client and the server, making it ideal for applications that require real-time updates.
