DCE

🕹️ Dungeon-Crawler-Engine

Modular dungeon crawler simulation for AI-driven gameplay, pathfinding experiments, and cryptographic save testing.
Under development by YSNRFD

🧠 DCE_ysnrfd – Procedural Dungeon Crawler Engine with AI & Secure Save System

🚀 Overview

DCE_ysnrfd is an extensible, modular dungeon crawler simulation built in pure Python.
It includes a secure save/load system using cryptographic HMACs, procedurally generated dungeons, an intelligent A* enemy AI, and a structured turn-based system.
Perfect for prototyping game mechanics, AI behavior, and simulation loops.

This project is for educational purposes, AI/ML pathfinding demos, and ethical development only.

✨ Features

🧱 Procedural Dungeon Generation
Uses recursive division with controlled randomness to generate interconnected dungeon layouts.
🧠 A* Pathfinding
Enemies use a priority queue with Manhattan heuristics for navigation and targeting.
⚙️ Component-Based Entity System
Players, enemies, and items are all modeled with clean, modular class structures.
🔒 Cryptographic Save/Load
Uses HMAC-SHA256 to verify save integrity. Saves are rejected if tampered.
⏱️ Turn-Based State Machine
Robust finite state system for clean transitions (menu → gameplay → endgame).
🧃 Inventory & Items System
Supports armor, weapons, potions, and quest items with metadata and effects.
📜 Type-Hinted & Extensible
Fully annotated for IDE support and future expansion.
📓 Verbose Logging System
Game states and events are logged to dungeon_crawler.log.

📦 Installation

1. Clone the repository

git clone https://github.com/ysnrfd/DCE.git
cd DCE-main

2. Run the program

Linux:

python3 dungeon_crawler.py

Windows:

python dungeon_crawler.py

🔧 Usage Examples

Run the main game loop

python dungeon_crawler.py

Use the map generation module alone

from dungeon_crawler import DungeonGenerator
map_data = DungeonGenerator(width=40, height=20).generate()
print(map_data)

Save and verify game state

from dungeon_crawler import SaveSystem, GameState

state = GameState(...)
SaveSystem.save(state, "game_state.encrypted")
verified = SaveSystem.load("game_state.encrypted")

🔐 Save System Details

Based on HMAC-SHA256 with secret key
Includes timestamp and anti-replay protection
Invalid or tampered saves are automatically discarded

🧠 Algorithms & Internals

Pathfinding: A with open/closed sets, priority queues (heapq)
Dungeon Generation: Recursive division + random room linking
State Machine: Enum-based game states and transitions
Secure Save: JSON serialization + hmac + secrets

🛣️ Roadmap

✅ Cryptographic save/load system

✅ Procedural generation engine

✅ A pathfinding and enemy AI

🔲 GUI version with Pygame or Pyxel

🔲 Quest/dialogue system

🔲 Plugin API for modding

🔲 Fog of war and minimap
