I'm trying to make a snake game just for fun and learning but I can't move my turtle. When I add the border lines and run it. My turtle can't move a bit. Problem pop up when I add the "if turtle.xcor()>290 or turtle.xcor()<-290 or turtle.ycor()>290 or turtle.ycor()<-290:" border lines

I've checked the lines and searched on the internet but i couldn't find a solution. I'm new so the problem might be easy.

As you guessed from the title, I'm making a beginner form of a snake game using the turtle module in Python. So far, everything is running smoothly, except for one single detail; the segments are not attached to the head, but they are rather lying inside the head itself on top of each other (you get what I'm saying?).
Here is what I wrote:
os.system("pause")
import turtle
import random
#Game Screen Set Up
screenWidth = 600
screenHeight = 600
screencolor = "#221C35"
screentitle = "Snake Game for Beginners"
screen = turtle.Screen()
screen.setup(width=screenWidth, height=screenHeight)
screen.bgcolor(screencolor)
screen.title(screentitle)
screen.tracer(0)
#Game Objects
head = turtle.Turtle()
head.speed(0)
head.shape("square")
head.color("#FFFFFF")
head.penup()
head.goto(0, 0)
head.direction = "stop"
food = turtle.Turtle()
food.speed(0)
food.shape("square")
food.color("#888888")
food.penup()
food.goto(0, -40)
segments = []
#Game Functions
def upwards():
head.direction = "up"
y = head.ycor() + 20
head.sety(y)
def downwards():
head.direction = "down"
y = head.ycor() - 20
head.sety(y)
def right():
head.direction = "right"
x = head.xcor() + 20
head.setx(x)
def left():
head.direction = "left"
x = head.xcor() - 20
head.setx(x)
#Keyboard Bindings
screen.listen()
screen.onkeypress(upwards, "Up")
screen.onkeypress(downwards, "Down")
screen.onkeypress(right, "Right")
screen.onkeypress(left, "Left")
while True:
screen.update()
if head.distance(food) < 20:
food.goto(random.randint(-290, 290), random.randint(-290, 290))
new_segment = turtle.Turtle()
new_segment.speed(0)
new_segment.shape("square")
new_segment.color("white")
new_segment.penup()
segments.append(new_segment)
for index in range(len(segments)-1, 0, -1):
segments[index].goto(segments[index-1].xcor(), segments[index-1].ycor())
if len(segments) > 0:
x = head.xcor()
y = head.ycor()
segments[0].goto(x, y)
if (head.xcor() > 290) or (-290 > head.xcor()) or (head.ycor() > 290) or (-290 > head.ycor()):
head.goto(random.randint(-290, 290), random.randint(-290, 290))
head.direction = "stop"
for segment in segments:
segment.goto(100000, 100000)

I'm trying to create an easier version of the snake game. Everything in the code looks ok for me but I can't make snake move as I want to. Can you help me why my code doesn't work? I don't understand why my code is not okay.
I searched for some similar games codes, but they all used time. and I couldn't understand the need for that.
Here is the code:
import turtle
import random
window = turtle.Screen()
window.screensize(600, 600)
window.title("Snake Eats Tomato Game")
window.bgcolor("skyblue")
window.tracer(0)
snake = turtle.Turtle()
snake.color("dark blue")
snake.shape("square")
snake.shapesize(1)
snake.speed(1)
snake.penup()
snake.goto(0, 100)
snake.direction = "stop"
def move():
if snake.direction == "up":
y = snake.ycor()
snake.sety(y + 20)
if snake.direction == "down":
y = snake.ycor()
snake.sety(y - 20)
if snake.direction == "left":
x = snake.xcor()
snake.setx(x + 20)
if snake.direction == "right":
x = snake.xcor()
snake.setx(x - 20)
point = 0
point_table = turtle.Turtle()
point_table.speed(0)
point_table.shape("square")
point_table.color("green")
point_table.penup()
point_table.hideturtle()
point_table.goto(-200, 200)
point_table.write(
"POİNT: {}".format(point), align="center", font=("Courier", 25, "normal")
)
def go_left():
if snake.direction != "right":
snake.direction = "left"
def go_right():
if snake.direction != "left":
snake.direction = "right"
def go_up():
if snake.direction != "down":
snake.direction = "up"
def go_down():
if snake.direction != "up":
snake.direction = "down"
window.listen()
window.onkey(go_left, "Left")
window.onkey(go_right, "Right")
window.onkey(go_up, "Up")
window.onkey(go_down, "Down")
tomato = turtle.Turtle()
tomato.penup()
tomato.color("tomato")
tomato.shape("circle")
tomato.speed(0)
tomato.setposition(random.randint(-300, 300), random.randint(-300, 300))
while True:
window.update()
snake.forward(3)
move()
if snake.xcor() < -330 or snake.xcor() > 330:
snake.right(90)
if snake.ycor() < -330 or snake.ycor() > 330:
snake.right(90)
if snake.distance(tomato) < 20:
point += 1
point_table.clear()
point_table.write(
"PUAN: {}".format(point), align="center", font=("Courier", 25, "normal")
)
tomato.setposition(random.randint(-300, 300), random.randint(-300, 300))
There were some 'errors' in your code, I'll try to adres most of them, one by one:
Instead of always calling snake.forward(3) in the while True, change snake.direction = "stop" to snake.direction = "right" as the starting movement. This will keep the while loop clean
The go_left (etc) functions had an if to check the reversed way, I've removed those, just overwrite the direction
snake.xcor() < -330 these won't work, not every screen is 330 pixels. You'll need to use window.window_width() and window.window_height() to get the current window size, and use those values to detect the edges
WHen you detect an edge, don't do snake.right(90), as this will instant move the snake. Just change the direction, to bounce it:
if (curX < window_max_left):
snake.direction = 'left'
if (curX > window_max_right):
snake.direction = 'right'
if (curY > window_max_up):
snake.direction = 'down'
if (curY < window_max_down):
snake.direction = 'up'
Applying those points, fixes the movement, and let the snake bounce of walls
* Please see the example recording below the code
The final code looks like:
import turtle
import random
window = turtle.Screen()
window.screensize(600, 600)
window.title("Snake Eats Tomato Game")
window.bgcolor("skyblue")

How it looked:
I am practicing some very simple projects and I found the snake game and handed to try my hand. I am pretty sure I copied the code completely but when I run it a small blue screen pops up for a split second and then disappears and doesn't say what's wrong.

You are getting a blue screen because the code is not complete there are some variables missing + the main game loop doesn't exits so the game simply crashes here is the complete code I got it from the same website further down Full Code

I'm new to programming and python. I somehow followed a guide and came up with a snake game. This game runs great. However, there are a few things that I need to add to make it much better.
First of all, I want to add some sort of start screen menu. Want it to have buttons. This start screen will tie into my next addition.
I am wanting to add a scoring system for teams or solo. I need it to selectable from the main screen. Like "play as a team" or "play on your own" buttons. If the team button is pressed then there will be 5 rounds, one round for each player. I have seen somewhat how to make the main menu screen using Tkinter. However, the other part about the teams and solo part seems to baffle me. Can't find a way to do it and can't find a guide online. I'm kinda stuck here.
Any help will be greatly needed and accepted. I will post the game code below so you guys can see it.
Thanks,
