#Question: Write a simple feature-complete snake game written in python using pygame.

#"""

# 1. Overview and imports

# Import pygame for the game
import pygame
pygame.init()

# Import image manipulation module for drawing image
from img_manip import ImageManip

# Define a list of items with their size and position
items = [
    ("pencil", 10, (-50, -50), (10, 30)),
    ("pen", 10, (-50, 40), (10, 60)),
    ("pencil", 5, (-50, -50), (5, 30)),
]

# Define a button with a rectangle and an event handler
button_rect = pygame.Rect(50, 50, 100, 50)
button_text = pygame.Rect(50, 100, 100, 20)
button_text_font = pygame.font.Font(None, 35)

button_text = button_text_font.render("Play", 1, (255, 0, 255))
button_rect.fill((0, 0, 0, 0))
button_rect.inset_abs(button_text, button_text_rect)

button = pygame.Rect(50, 100, 50, 20)

# 2. Drawing and animation

# Create a game screen and set its resolution
screen = pygame.display.set_mode((800, 600))

# Define a function to draw an image onto the screen
def draw_image(image, rect):
    images = pygame.image.load('img/' + image)
    screen_rect = pygame.Rect(rect)
    screen.blit(images, rect)

# Create an animation frame for each item
class AnimationFrame:
    def __init__(self, image, rect):
        self.rect = rect
        self.image = pygame.image.load('img/' + image)

frames = []

# Add a 'Play' button to the game
play_button = Button((600, 50), "Play", button_rect, button_text, button_rect.inflate(-2, -2), 0.1)
play_button.add_event(pygame.MOUSEBUTTONDOWN, play_button)

# Add items to the game
for item, size, position, text in items:
    draw_image(item, button_rect)
    image_manip = ImageManip(item, size)
    animation_frame = AnimationFrame(image_manip.image, button_rect)
    frames.append(animation_frame)

# Draw all the animation frames onto the screen
for f in frames:
    screen.blit(f.image, f.rect)

# 3. Implementing the snake AI

# Define a function to calculate the food positions for the snake
def calculate_food(x, y):
    return (x-1, y)

# Define a function to draw the snake onto the screen
def draw_snake(snake):
    # Draw the snake's body

        pygame.draw.line(screen, (255, 255, 0), segment_position[:-1], segment_position[1:])
        pygame.draw.line(screen, (0, 255, 0), segment_position[:-1], segment_position[-1])
    pygame.draw.line(screen, (0, 0, 0), segment_positions[0], (50, -20))

# Define a function to handle the snake collision and update its position
def snake_collision(snake, food_positions):
    # Check for collision with food
    for f in food_positions:
        if head.collidepoint(f):
