I Built a Multiplayer Sims Game with Javascript

Overview

In this tutorial, we'll explore how to add multiplayer networking features to a 3D game using React Three Fiber and Socket.io. Think of it as building a Sims-like or Animal Crossing-like experience, where multiple players can interact within the same virtual world.

This is the last episode in a seven-part series where we’ll build a multiplayer 3D game step by step.

The Final Step

In this last part, we’ll finalize our project, adding lobby management, a save system, smooth camera transitions, and realistic shadows. Plus, we’ll go over how to deploy your client and server so your project is live and playable online!

Insights and Skills

In this episode, you will:

• Set up a lobby system for room management.

• Improve the user experience with smooth camera transitions using CameraControls.

• Optimize avatars for better performance and persistence.

• Polish the game with final bug fixes, chat, and item interactions.

• Deploy your project using Elestio for hosting both the client and server.

By the end, you’ll have a fully functional multiplayer game you can share with others!
