Book Description

The Essential Guide to Creating Multiplayer Games with Godot 4.0 guides you in exploring the built-in network API for online multiplayer games, offering practical knowledge through concrete use cases.

Throughout the book, you'll assume the role of a network engineer in a fictional indie game studio, tackling real-world requests from your peers and gaining expertise in adding new network features to the studio's games. Following step-by-step instructions, you’ll go from making your first network handshake to optimizing online gameplay. You’ll learn how to sync players and pass data over the internet as you add online multiplayer features to a top-down shooter adventure game.

This book puts you in a fictional game project team where you set up your first online server before advancing to creating an online chat system and transitioning local gameplay to go online. With a focus on implementing multiplayer features, you’ll create shared world adventures and learn optimization techniques to allow more players to join your virtual world.

By the end of this book, you’ll have learned how to set up a client-server network, implement remote procedure calls (RPCs), sync node properties remotely, and optimize your games to create smooth online multiplayer experiences.
