Understanding Replication in Upside Engine

Welcome to the comprehensive guide on replication in Upside Engine! This tutorial will teach you how to create multiplayer games by understanding how objects are synchronized across clients.

What is replication?

Replication is the process of synchronizing game objects and their properties across multiple clients in a multiplayer environment. When a player moves their character, jumps, or performs any action, that information needs to be:

1. Sent to the server
2. Validated by the server
3. Distributed to all other connected clients

This ensures that all players see a consistent game state.
