today i tried to finish the snake game but it’s confusing
import os
import turtle
import time
import random
delay = .1
# Set up the screen
wn = turtle.Screen()
wn.title(“Snake Game by @TokyoEdTech”)
wn.bgcolor(“green”)
wn.setup(width=600, height=600)
wn.tracer(0) # Turns off the screen updates
# Snake food
food = turtle. Turtle()
food.speed(9)
food.shape(“circle”)
food.color(“red”)
food.penup()
food.goto(0,100)
segments = []
#Snake head
head = turtle.Turtle()
head.speed(8)
head.shape(“square”)
head.color(“black”)
head.penup()
head.goto(0,0)
head.direction = “stop”
#Functions
def move():
if head.direction == “up”:
y = head.ycor()
head.sety(y + 20)
if head.direction == “down”:
y = head.ycor()
head.sety(y – 20)
if head.direction == “left”:
x = head.xcor()
head.setx(x – 20)
if head.direction == “right”:
x = head.xcor()
head.setx(x + 20)
# Functions
def go_up():
head.direction = “up”
def go_down():
head.direction = “down”
def go_left():
head.direction = “left”
def go_right():
head.direction = “right”
#Keyboard bindings
wn.listen()
wn.onkeypress(go_up, “w”)
wn.onkeypress (go_down, “s”)
wn.onkeypress(go_left, “a”)
wn.onkeypress(go_right, “d”)
# Main game Loop
while True:
wn.update()
# Check for a collision with the border
if head.xcor()>290 or head.xcor()<-290 or head.ycor()>290 or head.ycor()<-290:
time.sleep(1)
head.goto(0,0)
head.direction = “stop”
# Clear the segments list
segments = []
# Check for a collision with the food
if head.distance(food) <20:
# Move the food to a random spot
x = random.randint(-298, 290)
y = random.randint(-290, 290)
food.goto(x,y)
# Hide the segments
for segment in segments:
segment.goto(1000, 1000)
# Add a segment
new_segment = turtle. Turtle()
new_segment.speed(8)
new_segment.shape(“square”)
new_segment.color(“grey”)
new_segment.penup()
segments.append(new_segment)
# 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 to where the head is
if len(segments) > 0:
x = head.xcor()
y = head.ycor()
segments[0].goto(x,y)
move()
#Check for head collision with the body segments
for segment in segments:
print(“distance”,segment.distance)
if segment.distance (head) < 20:
time.sleep(1)
head.goto (0,0)
head.direction = “stop”
# Clear the segments list
segments = []
time.sleep(delay)
wn.mainloop()
that’s what i did
