S2E4 JSON Configs, Databases, and RPC (Patreon)

In this episode, we dive into managing our players and mod data using json configuration files, databases, and RPCs.

You'll learn how to efficiently store and retrieve player information with JSON files, how to work with maps for structured data storage, and how to use RPCs to sync player data between the client and server.

By the end of the lesson, you'll have a solid understanding of how to create a dynamic, persistent player data system in your DayZ mods.
