Day 21 of 100

Finished my snake game! It's supposed to be simple to play and yet my score never seems to go above five. What's your high score?

I also learnt about slicing lists and tuples and what is class inheritance.

main.py

from turtle import Screen
from snake import Snake
from food import Food
from scoreboard import Scoreboard
import time

screen = Screen()
screen.setup(width=600, height=600)
screen.bgcolor("black")
screen.title("My Snake Game")
screen.tracer(0)

snake = Snake()
scoreboard = Scoreboard()
food = Food()

screen.listen()
screen.onkey(snake.up, "Up")
screen.onkey(snake.down, "Down")
screen.onkey(snake.left, "Left")
screen.onkey(snake.right, "Right")

game_is_on = True
while game_is_on:
    screen.update()
    time.sleep(0.1)

    snake.move()

    if snake.head.distance(food) < 15:
        food.refresh()
        scoreboard.increase_score()
        snake.extend()

    if snake.head.xcor() > 295 or snake.head.xcor() < -295 or snake.head.ycor() > 295 or snake.head.ycor() < -295:
        scoreboard.game_over()
        game_is_on = False

    for segments in snake.segments[1:]:
        if snake.head.distance(segments) < 10:
            game_is_on = False
            scoreboard.game_over()

screen.exitonclick()
