Multiplayer Overview

RPG Engine v6 is built with multiplayer as a core part of the framework and is designed primarily for listen-server gameplay. The networking model is server-authoritative, which means the server is responsible for validating and applying gameplay-critical actions, while clients handle input, presentation, and local responsiveness.

The goal of this approach is to keep gameplay consistent across all connected players while preserving the flexibility needed for different genres such as shooter, survival, adventure, and co-op RPG projects.

Networking Model

The framework follows a server-authoritative architecture. Clients can request actions, but the server remains the final authority for gameplay decisions such as state changes, combat results, inventory updates, item usage, spawning, and other important gameplay events.

This keeps multiplayer behavior reliable and helps ensure that all players share the same gameplay state during a session.

Fully Replicated Systems

RPG Engine v6 is designed so that all major gameplay systems are replicated. This includes the systems that drive combat, inventory, equipment, character states, AI interactions, vehicles, building, and other core gameplay features.

Because replication is treated as a foundational part of the framework rather than an afterthought, multiplayer support is deeply integrated into the overall architecture.

Modular Multiplayer Architecture

One of the main strengths of v6 is its modular design. Instead of relying on one massive character blueprint, the framework distributes logic across focused systems and components coordinated through the mediator-based architecture.

This makes multiplayer behavior easier to maintain, easier to scale, and easier to reason about, especially as projects grow in complexity.

Client and Server Roles

In practice, the server owns gameplay truth, while clients are responsible for sending requests and presenting feedback to the player. UI, camera behavior, effects, animation feedback, and similar presentation elements can react locally, while authoritative gameplay results remain controlled by the server.

This separation helps the game feel responsive without sacrificing multiplayer consistency.

Why It Matters

Multiplayer in RPG Engine v6 is not just a technical add-on. It is part of the framework’s core design, influencing how gameplay systems communicate, how data is replicated, and how features are structured across the project.

That makes the framework suitable for developers who want to build cooperative or multiplayer-focused games on top of a system that already treats networking as a first-class concern.
