Snake Game

A classic Snake Game implemented in Python using the Turtle library.

Introduction

This project is a simple implementation of the Snake Game using Python's Turtle library. The game involves controlling a snake to eat food pellets, growing longer with each pellet eaten, while avoiding collisions with the walls or itself.

Features

  • Classic Snake gameplay experience.
  • Score tracking and display along with high score.
  • Simple controls using arrow keys.

Requirements

  • Python 3.x
  • Turtle library (Usually comes pre-installed with Python)

Installation

  1. Clone the repository to your local machine:

How to Play

  • Use the arrow keys to control the direction of the snake.
  • The snake will continuously move in the current direction.
  • Eat food pellets to grow longer and increase your score.
  • Avoid collisions with the walls or the snake's own body.
  • The game ends when the snake collides with a wall or itself.

Snake Game - Documentation

This document provides an overview of the methods available in the Python files food.py, scoreboard.py, and snake.py, which are used in the Snake game.

food.py

Methods

__init__(self)

  • Initializes a new instance of the Food class.
  • Sets up attributes such as shape, color, size, and initial position of the food.

refresh(self)

  • Generates random coordinates within the screen boundaries and moves the food to that position.

scoreboard.py

Constants

  • ALIGN: Center alignment for text display.
  • FONT: Font specifications for text display.

Methods

__init__(self)

  • Initializes a new instance of the Scoreboard class.
  • Sets up attributes such as current score, font, color, and initial position of the scoreboard.

game_over(self)

  • Displays "GAME OVER" message at the center of the screen.

update_score(self)

  • Updates the displayed score on the scoreboard.

increase_score(self)

  • Increments the score by 1 and updates the scoreboard display.

snake.py

Constants

  • MOVE_DIST: Distance the snake moves in one step.
  • UP, DOWN, LEFT, RIGHT: Directional constants for snake movement.
  • STARTING_POSITIONS: Initial positions for the segments of the snake.

Methods

__init__(self)

  • Initializes a new instance of the Snake class.
  • Sets up attributes such as segments list and the snake's head.

create_snake(self)

  • Creates initial segments of the snake at predefined positions.

add_segment(self, position)

  • Adds a new segment to the snake at the specified position.

extend_segment(self)

  • Extends the length of the snake by adding a new segment to its tail.

move(self)

  • Moves the snake forward by updating the positions of its segments.

Movement Methods: up(self), down(self), left(self), right(self)

  • Change the direction of the snake's head based on user input.
