System Requirements Document for Gilded-System

Introduction

The "Gilded-System" is a city transportation simulation game designed to provide an interactive and engaging experience for users. The game is built using Flutter and follows an automated, self-correcting development loop to ensure robustness and scalability. This document outlines the system requirements for the Gilded-System, focusing on its core functionalities, user interactions, and future expansion capabilities.

System Overview

The Gilded-System is a simulation game where players manage a city's transportation network. The game features a dark theme with realistic elements such as roads, buildings, trees, and bus stops. The core gameplay loop involves managing buses that follow routes, picking up and dropping off passengers, and generating revenue. The system is designed to be expandable, allowing for future additions like trains, airports, and various buildings.

Functional Requirements

• As a Player, I should be able to view an interactive city map that allows zooming and panning.
• As a Player, I should be able to add bus stops by double-tapping on the map.
• As a Player, I should be able to manage multiple buses with different routes, capacities, and colors.
• As a Player, I should be able to simulate passenger generation, including rush hour scenarios.
• As a Player, I should be able to create and manage routes by selecting stops.
• As a Player, I should be able to add or delete stops via double-tap.
• As a Player, I should be able to view a financial dashboard showing revenue by bus, stop, and route.
• As a Player, I should be able to control the game with play/pause and a speed slider ranging from 0.5x to 3x.
• As a Developer, I should ensure the architecture supports future expansions like trains and airports.
• As a Developer, I should ensure the game state updates properly without crashes.
• As a Developer, I should ensure smooth animations for bus movements along routes.
• As a Developer, I should ensure memory management by disposing of controllers properly.
• As a Developer, I should ensure UI performance is optimized using appropriate Flutter widgets.

User Personas

• Player: The primary user who interacts with the game, managing the transportation network and making strategic decisions to optimize revenue.
• Developer: The individual responsible for maintaining and expanding the game's features and ensuring its smooth operation.

Core User Flows

• Player opens the game -> Views city map -> Adds bus stops -> Creates routes -> Starts simulation -> Monitors revenue on the dashboard.
• Player adjusts game speed -> Observes passenger generation -> Manages bus capacities -> Optimizes routes for maximum efficiency.
• Developer tests game state -> Ensures map renders correctly -> Verifies smooth animations -> Checks for memory leaks.

Signature Design Concept

The Gilded-System features a dynamic cityscape that evolves as the player interacts with it. The homepage presents a 3D interactive map using @react-three/fiber and @react-three/drei, where buildings and roads rise and fall based on player actions. As players zoom in, the map transitions smoothly, revealing intricate details like bus stops and passenger movements. Hovering over elements provides real-time data, and clicking on buses or stops opens detailed management panels. The map's lighting changes with the in-game time, creating a living, breathing city environment.

Interaction Model & Motion Direction

The landing page employs a "parallax" interaction model, providing a layered depth effect as users scroll. Decorative elements like clouds and distant cityscapes move at different speeds, creating an immersive experience. Internal pages, such as the dashboard and management screens, use an "animated" model with scroll-triggered reveals and hover transitions for a polished look.

Non-Functional Requirements

• The system must handle up to 10,000 concurrent users without performance degradation.
• The game should load within 3 seconds on standard broadband connections.
• The UI must be responsive and function correctly on both desktop and mobile devices.

Tech Stack

• Frontend: Flutter
• Backend: Not specified (assumed to be managed within the Flutter framework)
• Database: Not specified (assumed to be managed within the Flutter framework)
• AI Models: Not applicable
• Local Orchestration: Not specified
• Server-side Orchestration: Not specified

Assumptions and Constraints

• The game will be developed and tested primarily for the Saudi Arabian market, considering local preferences and time zones.
• Future expansions must integrate seamlessly with the existing architecture without requiring significant rewrites.

Glossary

• Bus Stop: A designated location where buses pick up and drop off passengers.
• Route: A predefined path that buses follow within the city.
• Passenger: A simulated entity that uses the bus system.
• Revenue: The income generated from passenger fares.
• Rush Hour: A period with increased passenger generation, simulating real-world traffic patterns.
