How to change the background to a custom picture instead of a colour

thanks

nice game

Nice game, you can create classes for the snake body, scoreboard, food and maybe wall. Then the code will be more structured :)

Heya. Probably you need to install tkinter for ubuntu. To do so, go to the terminal and type: sudo apt-get install python3-tk Here is a link to my free Intro to Python e-book - you may find it helpful: https://drive.google.com/file/d/1ajYJZLGUaVmNbuG98LnRfHMTzvnZx9el/view?usp=share_link Keep on coding!

how would one add a border around the playable area, as i would like to enlarge the game screen but a border around the playable are would make it easier to play

You can draw lines like so: turtle.penup() turtle.goto(x1, y1) turtle.pendown() turtle.goto(x2, y2)

Hiya, Download the python file. Open it in your preferred IDE, and run the program. Use the arrows to move the snake around.

Great code, here is is tutorial to make fruit ninja game in python

its amazing game nice! I'm still learning how to code python thanks for sharing this!

Hey! I was wondering is there a way I can change the background from green to checkers?

You can

 /bin/python3 "/home/devil/Code/Python/Turtle/Snake Game/snake_game.py"
Traceback (most recent call last):
  File "/home/devil/Code/Python/Turtle/Snake Game/snake_game.py", line 4, in <module>
    import turtle
  File "/usr/lib/python3.10/turtle.py", line 107, in <module>
    import tkinter as TK
ModuleNotFoundError: No module named 'tkinter'

go to terminal and type pip install tkinter, i hope it will work

arrow keys are not working in ubuntu how to play the game

Change each of the letters for up, down, etc in the "onkeypress" statements to correspond to the literal words "Up" "Down" "Left" and "Right" in place of the 'wsad' options, and you'll get keyboard arrow functionality.

I'm using JDoodle on my school laptop so that might be the problem as a whole, but the only error I get is always:

Dependency download failed - --null

Hiya, Yeah, most online IDEs don't work well with the Turtle module. You'll need a full install to get that working correctly.

I think this game is really cool! Simple and fun snake concept with great Python implementation. Key controls are convenient, and the mechanics of eating food and making the snake bigger add interest. However, in my opinion, the game can be improved.

How to play?

WASD

Thanks for the game. It was fun to play. Needs a pause button and the sync is off when turning left, right, up and down but hopefully i can try add that if i am allowed.
