# A very simple snake game

# Imports
import turtle
import time
import random


# Score and delay
score = 0
high_score = 0
delay = 0.1


# Set up the screen
wn = turtle.Screen()
wn.title('Snake Game by Arpit')
wn.bgcolor("green")
wn.setup(width=700, height=700)
wn.tracer(0)  # Turns off screen updates

# Outline of the playing field
pencil = turtle.Turtle()
pencil.speed(0)
pencil.shape('circle')
pencil.color('black')
pencil.penup()
pencil.hideturtle()
pencil.goto(310,310)
pencil.pendown()
pencil.goto(-310,310)
pencil.goto(-310,-310)
pencil.goto(310,-310)
pencil.goto(310,310)
pencil.penup()


# Snake head
head = turtle.Turtle()
head.speed(0) # 0 is the maximum animation speed of turtle module
head.shape("circle")
head.color('black')
head.penup()
head.goto(0,0)
head.direction = 'stop'

# Snake Food
food = turtle.Turtle()

# Contains information about snake body

# Pen
pen = turtle.Turtle()

### Functions
# Function to update the score
def update_score():
    pen.clear()
    pen.write('Score: {} High Score: {}'.format(score, high_score), align='center', font = ('Courier', 24, 'normal'))

# Functions that move snake in response to keyboard keys
def go_up():
    if head.direction != 'down':
        head.direction = 'up'
def go_down():
    if head.direction != 'up':
        head.direction = 'down'
def go_left():
    if head.direction != 'right':
        head.direction = 'left'
def go_right():
    if head.direction != 'left':
        head.direction = 'right'

# Function that helps the snake move
def move():
    # Move the end segments first in reverse order
    for index in range(len(segments)-1, 0, -1):
        x = segments[index-1].xcor()
        y = segments[index-1].ycor()
        segments[index].goto(x,y)
    # Move segment 0 to the head
    if len(segments) > 0:
        x = head.xcor()
        y = head.ycor()
        segments[0].goto(x,y)
    # Keep the snake moving in the same direction
    if head.direction == 'up':
        head.sety(head.ycor() + 10)
    if head.direction == 'down':
        head.sety(head.ycor() - 10)
    if head.direction == 'left':
        head.setx(head.xcor() - 10)
    if head.direction == 'right':
        head.setx(head.xcor() + 10)

# Function that tells the game what to do when collision occurs
def collision():
    time.sleep(0.5)
    head.goto(0,0)
    head.direction = 'stop'
    # Hide the segments
    for segment in segments:
        segment.hideturtle()
    # Clear the segments list
    segments.clear()
    score = 0
    update_score()
    # Reset the delay
    delay = 0.1

### Keyboard bindings
wn.listen()
wn.onkeypress(go_up, 'Up')
wn.onkeypress(go_down, 'Down')
wn.onkeypress(go_left, 'Left')
wn.onkeypress(go_right, 'Right')

### Loop that runs the game code
while True:
    # Updates the window repeatedly
    wn.update()

    # Check for collision with border
    if head.xcor()>290 or head.xcor()<-290 or head.ycor()>290 or head.ycor()<-290:
        collision()

    # Check if the snake eats the food
    if head.distance(food) < 20:
        # Move the food to a random spot
        food.goto(random.randint(-290,290),random.randint(-290,290))
        # Add a segment
        new_segment = turtle.Turtle()
        new_segment.speed(0)
        new_segment.shape('circle')
        new_segment.color("grey")
        new_segment.penup()
        segments.append(new_segment)
        # Shorten the delay - this increases speed of snake as it gets longer
        delay -= 0.001
        # Increase the score
        score += 10
        if score > high_score:
            high_score = score
        update_score()

    # Move the snake in the game
    move()

    # Check for head collision with the body segments
    for segment in segments:
        if segment.distance(head) < 10:
            collision()
    # Delay so that we can see things move
    time.sleep(delay)

# Makes the window visible and runs everythings
wn.mainloop()
