Cryptis - Game Code Documentation

main.py

This file contains the main logic of the game Cryptis, including the main menu, game modes, and transition management.

Features:

• Main Menu: Allows the user to start a new game, view credits, or quit.
• Choose Word: Input a word to encrypt.
• Difficulty Selection: Choose between easy or hard game modes.
• Game Initialization: Includes background music, assets, and main loop.

game.py

Handles the game logic for easy and hard difficulty modes.

Functions:

1. extract_numbers: Converts a string of encrypted text into numerical values.
2. Victoire: Displays the victory screen.
3. game_easy: Implements the easy game logic with an 8x14 grid.
4. game_hard: Implements the hard game logic with an 8x14 grid.

crypto.py

Provides cryptographic operations for encoding and encryption in the game.

Features:

• generate_ternary_table: Creates a ternary representation for the alphabet.
• mot_to_ternaire: Converts words into their ternary representation.
• apply_noise_to_key: Adds noise or transforms the encryption key.
• apply_bayesian_encoding: Encodes a key using a Bayesian Network.

---

config.py

Stores the configuration variables for the game.

Key Configurations:

• Screen dimensions: SCREEN_WIDTH = 1280, SCREEN_HEIGHT = 720
• Colors: WHITE, BLACK, LIGHT_BLUE, DARK_BLUE
• Grid size: GRID_WIDTH = 8, GRID_HEIGHT = 8

---

ui.py

Defines UI components, such as buttons and input boxes.

Features:

• Button: A clickable button with hover effects.
• draw_input_box: Draws and manages input boxes for user interaction.

Notes

• This game uses a combination of Bayesian encoding and ternary transformations for its encryption logic.

• The game_easy and game_hard modes are grid-based puzzles with specific win conditions.

• Customize the music, fonts, and visuals by replacing the assets in the respective folders.

• This game is inspired by the Cryptris game projet.
