How to Use WebSockets in Unreal Engine

Download Core to create games for FREE: Join the Game Creator Challenge: In this video, we go over how to use the WebSockets module in an Unreal Engine game. The WebSockets module includes only client functionality. Therefore, we use the module to establish a connection between Unreal clients and a sample NodeJS server, send and receive messages over that connection, and close that connection. Since the WebSockets module is not natively exposed to blueprints, we wrote some C code in the GameInstance and Character classes in order to not only connect to and disconnect from a server but also send messages to the server and implement event handlers in the IWebSocket interface. At the end of the video, we test multiple packaged clients simultaneously by having them all connect to the same server and send messages to each other via WebSockets. *****IMPORTANT LINKS***** More information about the WebSocket protocol: Unreal Engine project code that was used in this video: WebSocket server code that was used in this video: Download and install NodeJs: Download and install Git: How to expose C code to blueprints: Cool things you can make with WebSocket: Unreal Engine API Reference for the WebSockets module: *****IMPORTANT COMMANDS***** cd [directory-path] cd “[path-with-spaces]“ git clone npm install node server To end the server: Ctrl-C Windows: cls Linux: clear -WINDOWED To fit make a window to take up either half or a quarter of the screen on Windows: Windows key any arrow key How to support the channel: Get a shirt or sweatshirt with free shipping (Use code “SHIP“ at checkout): Become a member: Support us on Patreon: Donate to our PayPal: Sponsor us on Github: Social media links: Discord: Twitter: Instagram: Facebook: 0:00 Intro 1:09 Sponsor 2:33 Creating a WebSocket connection 10:04 Adding WebSocket event handlers 14:34 Sending data from client to server 18:10 Testing with multiple packaged clients simultaneously 20:40 Outro #unrealengine #websocket #ue5
