Introduction

The Global Overview section provides a high-level understanding of how the different parts of the engine interact:\ server simulation, client rendering, networking, and the shared ECS architecture.

This section is the recommended starting point before diving into the server or client pages.\ It explains:

the core principles of the project
how responsibilities are divided between the server and the client
what role the ECS plays in both sides
how networking ties everything together
how the multi-instance architecture enables concurrent game sessions
how the different threads and subsystems communicate
how snapshots, prediction, and interpolation work

You will also find a complete architecture diagram summarizing the entire workflow of the engine.

After reading this section, you will have a clear mental model of:

the overall data flow
the purpose of each subsystem
where each piece of logic lives
how the engine maintains determinism, performance, and visual smoothness

From here, you can continue to:

Multi-Instance Architecture to understand how the server supports multiple concurrent games
Server Architecture to understand authoritative simulation
Client Architecture to see how visuals and networking are handled
ECS Overview to learn how entities, components, and systems are implemented

The following pages break down each major part of the engine step by step.
