- 1. Detect collision with food Create food.py
from turtle import Turtle

Add to main.py
from food import Food
food = Food()
if snake.head.distance(food) < 15:
food.refresh()
Complete main.py

self.write(f"Score: {self.score}", align=ALIGNMENT, font=FONT)
def increase_score(self):
self.score += 1
self.clear()
self.update_scoreboard()
main.py ADD
from scoreboard import Scoreboard
score = Scoreboard()
under if statement add score.increase_score()
from turtle import Screen
from snake import Snake
from food import Food
from scoreboard import Scoreboard
import time
# Screen setup
screen = Screen()
screen.setup(width=600, height=600)
screen.bgcolor("black")
screen.title("SnakeGame")
screen.tracer(0)

score = Scoreboard()
screen.listen()

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()
score.increase_score()
screen.exitonclick()
