MenuSystem

A comprehensive Unreal Engine 5.7 multi-variant game framework featuring multiplayer sessions, AI systems, and modular game mode architecture.

Overview

MenuSystem is a flexible game development template that demonstrates UE5 best practices through three distinct game variants:

• Shooter - First-person shooter with complete weapon systems and AI enemies
• Horror - First-person horror with stamina mechanics and atmospheric gameplay
• Lobby - Multiplayer lobby system for player matchmaking

Features

Core Systems

• Enhanced Input System - Modern input framework with switchable mapping contexts
• Multiplayer Sessions - Full Steam integration with session creation, discovery, and joining
• First-Person Framework - Character system with head-mounted camera and separate first-person mesh

Design Patterns

• Interface Pattern - IShooterWeaponHolder for weapon interaction
• Delegate Pattern - Event-driven communication (OnBulletCountUpdated, OnDamaged, etc.)
• Subsystem Pattern - Global session management via GameInstanceSubsystem
• Controller Pattern - Separation of input, UI, and respawn logic

Requirements

• Unreal Engine 5.7+
• Visual Studio 2022
• Steam SDK (for multiplayer features)
