Thanks bro
Sir is code ko copy kar sakte h?
how can I pack all code so I can use it with other modules too..
I love your videos. so easy to understand why a certain line of code is written thanks to how you've explain it and easy to follow. thanks man
Your tutorials are very understandable.Ive been binging on your full 12 hour python course and im about to finish it.Thank u
Ik this is from a year ago but did you end up finishing it? Where are you now with your skills
hey
Ran through this whole video several times. Opened up Pycharm and ran with it. It was super easy to follow, and I now have a new game to play with.

bro you are the TUTORIAL MASTER !!!
Please help how to get the white game table on the game tkinter
Output is stop only for 1second what to do
@@shaliniminz2743 same with me
Either I'm finally starting to understand python, or you are just a very good teacher.
He is a good teacher
probably both
If you want to make a restart buton not to rerun the code each time, here is how you can make it:
create a restart function:
def restart_game():
global snake, food, score, direction
# Reset game variables to initial values
canvas.delete(ALL)
snake = Snake()
food = Food()
score = 0
direction = 'down'
label.config(text="Score:{}".format(score))
next_turn(snake, food)
and add a restart button to the window:
restart_button = Button(window, text="Restart", command=restart_game, font=('consolas', 20))
restart_button.place(x=0, y=0)
BTW, Thanks @Bro Code, watched you 12 hour tuturial, really usefull, making progress already
been looking for this, thanks
class Food:
def __init__(self):
while True:
x = random.randint(0, (GAME_WIDTH / SPACE_SIZE) - 1) * SPACE_SIZE
y = random.randint(0, (GAME_HEIGHT / SPACE_SIZE) - 1) * SPACE_SIZE
# Check if the new food coordinates overlap with the snake
if (x, y) not in snake.coordinates:
break
self.coordinates = [x, y]
canvas.create_oval(x, y, x + SPACE_SIZE, y + SPACE_SIZE, fill=FOOD_COLOR, tag="food")
*******
code, so that food is within win size and not overlap.
how is it going so far? are you making any progress?

I also encountered the same situation. But I coded according to yours and got an error
Im geting positional arguments follow keyword arguments. Why is that and how to fix it?
Thank you, sir, Good project with a good explanation.
Well spent 30 minutes of Saturday morning! :) Great job, I would like to code this error-less way too ;)
Thank you for this amazing series! Getting myself started in learning programming :)

I think that you have to write False twice because it means window width and height , two values . Very good tutorial
Thanks for taking the time to put all this on the internet for all of us to look at free. Very awesome
nice simple game tutorial Bro.. Thank you so much for this tutorial..
Thanks u v much, run my first GUI based game, loved it.
Ur knowledge of subj is v good, u teach as evth is a piece of cake. Additionaly, ur voice is like a robot, consistent and soothing to hear.
Ur videos are begginer friendly, i will finish as many i can.
Thanks for sharing ur knowledge with us and making us better coder.
Stay safe. Keep progressing in right direction.

Great job! One day I'll be programming like you! =] Thanks for sharing this programming lesson. One more subscriber.
Very cool and instructional. Thanks Bro!!
hey bro thanks for the tutorial it really helped me. This was my first gaming project I have done and I'm really satisfied. Python snake game 🐍..... (I subscribed :) )
Thank you for this. I'm really excited to learn and develop my coding skills
thanks a lot for sharing it! you are helping to make learning python more fun and enjoyable :)
Great Tutorial.. I will implement the following by myself > Highscore System and "Food spawn in Body check". Also, there is a problem with the code. Windows Geometry expects inters and as the code is, there will be a problem if dividing by SPACEequals to 0.5... what I did in the end was just add the int to x and y. If you
x = int((screen_width / 2) - (window_width / 2))
y = int((screen_height / 2) - (window_height / 2))
window.geometry(f"{window_width}x{window_height}+{x}+{y}")
hey did you figure out how to implement the high score system? because i can't figure it out.
BRO THANKS, YOU SAVED ME SO MUCH TIME
i am so happy i have searches the whole for a tutorial to make a game using python
These codes are really understandble, i did same thing with you while getting what you're saying
you are a really good teacher
Thanks man i appriciate you efforts 👍👍it amazing tutrorial it helped me a lottt .... I expect more tutorials😊😊
Thanks for the lesson! It was harder to fully understand than the previous projects, but the result is much more enjoyable:) And there is a lot of space to customize the game and to practice the previous topics - adding customization buttons (colours, space size etc), various speed tweaks etc. For example, here I added the auto-incrementing of the snake speed:
if x == food.coordinates[0] and y == food.coordinates[1]:
global score
global speed
score += 1
if speed > 60: speed -= 1
score_label.config(text='Score: {}'.format(score))
canvas.delete('food')
food = Food()
A small note - there is a "suicide" issue (when the direction is changed too fast, i.e. snake is moving down and if you click left and then instantly up (without allowing the snake to move left), the snake will eat itself. To fix this, I changed the key bindings to set a variable instead of calling a function:
new_direction = StringVar(window)
new_direction.set('down')
window.bind("", lambda x:new_direction.set('up'))
window.bind("", lambda x:new_direction.set('left'))
window.bind("", lambda x:new_direction.set('down'))
window.bind("", lambda x:new_direction.set('right'))
window.bind("", lambda x:new_direction.set('up'))
window.bind("", lambda x:new_direction.set('left'))
window.bind("", lambda x:new_direction.set('down'))
window.bind("", lambda x:new_direction.set('right'))
After that, I added a check to the main function to see if a new direction is different from the current direction:
global direction
global new_direction
# Change the direction of the snake
if new_direction.get() == 'up' and direction != 'down': direction = 'up'
if new_direction.get() == 'down' and direction != 'up': direction = 'down'
if new_direction.get() == 'left' and direction != 'right': direction = 'left'
if new_direction.get() == 'right' and direction != 'left': direction = 'right'
This check is performed before everything, and this allows to change the snake direction only once per main function tick
what if I would like to make the food will not land on the body of the snake (every block after the head of the snake)??
hi may i know how to solve the "NameError : name 'speed' is not defined? I'm trying to increase the speed but it shows this statement
hey, can you tell us more about other improvements you did to the code ?
@@sroouchiam check your variable name(ikr 6 months late)
if i wanted to put a restart button when there's the "GAME OVER" text , how do you recommend i do it?
Bro u are tutorial master!!! U gave me ideas to make my final project for my python class !!!!!
Completely done!!!!!!!
Thank you Sir
Nice!👍 A quick and easy snek game.
you are amaaaaaaazing !!!
i hope you make a series about kivy library and the other important libraries
i've made this game by this video! thank you from japan!
great course for beginners
nice and good explanAtion. Thanks
for collosion detection you could just turn the squares list into a set and check if its smaller than the original list
At 5:50 why did we add window.update() line after packing label and canvas, is it nesscessary?
And why don't we create the label and canvas after setting the window size and position to be at the center?
Thank you so much, this really helps. Now my teacher would be really happy watching this . we made indicator before a s our FOAE project now this really looks cool!!😁
thanks for the step by step tutorial
Nice game maker tutorial bro, i did it on live stream, it was awesome
Hey bro 19/11/21 I finish your python tutorial beginning .Thanks Thanks you so much
Thank you so much
Seems like I found a very minor flaw within the x/y part of the class Food: section. I don't know if its just idle being idle and is not working properly for reasons beyond me or just a new update thing, but x = random.randint(0, (GAME_WIDTH / SPACE_SIZE)-1) * SPACE_SIZE and y = random.randint(0, (GAME_HEIGHT / SPACE_SIZE)-1) * SPACE_SIZE doesn't seem to function and will cause a "TypeError: 'float' object cannot be interpreted as an integer" unless you replace the / in the code with a //
ie: x = random.randint(0, (GAME_WIDTH / SPACE_SIZE)-1 bad, no good. x = random.randint(0, (GAME_WIDTH // SPACE_SIZE)-1 good, python likey.
This isn't meant to discredit your code btw @BroCodez, just giving a heads up for anyone experiencing the same troubles I'm currently facing.
edit: forgot to replace the // with a / on all of the bad codes lel
THANK YOU SO MUCH DUDE I WAS HAVING THE SAME PROBLEM ITS FIXED NOW
THANKS A LOTT BROOO!!! I WAS LITERALLY STRUGGLING SINCE YESTERDAY!!
THANK YOU!!
This was really helpful, Thank you!
Is there anyway to make a main menu in tkinter? I want to make this game but with a main menu, not sure if its possible or if i should just use pygame
The code does not check the position of the food so it can spawn on top of the snake. Other than that, great video.
also if you press two non opposite arrow keys rapidly the snake will do a 180 degree turn resulting in game over
Do we need to download the file game before starting programming? I mean the file contains some image folders, sound folders,...stuff like that ;-;
Thank you so much Sir ...!!!
Love from Bharat...!!!
very nice
I'm asking for help cuz I don't know much of python, but how can I make the code work? it keeps saying that a "float" cannot be used as an "int", and then proceed to show me wich lines aren't working (those being line 159, 33, 336 and 312). I know on paper what this means but I don't know how to correct the error. How?
Thanks for the tutorial!
Can someone help on how to disable food from spawning in the snake body?
As the snake gets longer it gets more common.
Thank you so much for the lesson, very easy to follow for a super beginner like me!! I have a question if in the "Background" I want to put a picture of a snake, for example, how can do it?
I can tell you the solution but do you want it now
Amazing explanation. Short, crisp and to the point.
Unknowingly you taught me a lot about classes and objects.
Thanks!
Edit : I am trying to add on to your project by making changes such as snake head of different color, storing a high score, pause button and a restart button!
I feel like my attention span doesn't exist while I work on whatever while listening to bro code talk about snakes in the background of my mind...
Amazing tutorial 👍
that's a great tutorial and the 1st snake I do for the first time for me
Imagine how much better it would be if javascript was able to be added to it
this video is very helpful! but I kinda got stuck on the 'label' part...
when I typed : label =label(window, text="Score:{}".format(score), font=('consolas', 40))
it says: name 'label' is not defined. Did you mean: 'Label'?
what do I need to do to fix it?
try this: label = Label(window, text="Score:{}".format(score), font=('consolas', 40))
what if I would like to make the food will not land on the body of the snake (every block after the head of the snake)??
Amazing! I apreciate your time...
Бро, ты лучший, долго пытался освоить питон и только ты смог мне в этом помочь
Hey how did you converted into pixels ? At 9:49
Superb tutorial. Next time, can you show a pixel graph for reference. I was trying to understand the calculations for how the window is centered for a while. I eventually saw that the pixel graph is drastically different from the Cartesian graph (the graphs we use in high school and college).
Excellent tutorial!
Nice tutorial
it is showing me a problem :
Expected indented block Pylance [Ln 95, Col 1]
in the check collisions but i have followed everything nicely as you explained in the video
Great job. I
I love ur videos.Keep it up
Thank you bro code I like all your videos
WOW
Do you have some recomended books for learning Python???
anything by O'Reilly
@Bro Code Hello. Good day! Can you do a video on how to add menu buttons? Thank you.
Your tutorials are amazing. i fell like a pro while just watching your videos. but i would like to know how to transform those codes into an executable file.
Bro you are the best, I tried to master python for a long time and only you could help me with this
what app do you use to run the python?
Followed along. Got so lost. Classes and functions are still kind of new for me, I did end up finishing the project tho.
question: which is better for simple projects and games , Tkinter, pygame or something else?
and what are the pros and cons of each(Tkinter vs Pygame)?
Note: I havn't learned about pygame yet
Pygame uses sdl2 which is written in c++. This makes it more performant but you still lose about 60% of the c++ performance. Thinker on the other hand is a gui library and is not made for games
@@PreslavKolev thanks for the information
thanks, very good video
Hi, great Video but i have a question...
How does the game over screen get triggered? i know its working because i followed and tried but what told the gameover screen to appear? Is it just because check_colission returned true and next thing in script is this screen? is this how it works?
Great Video
very good video!!! It took me about 2 hours, but I eventually got it right 😅Greetings from Mexico!
How many days are you learning python language
Great concise video.
My food wasn't appearing in proper coordinates. Took me ages to check line by line lol
howd u you solve this? i have the same error too I think, of the food being seen as a float (maybe u had the same problem??)
@@supermoneyd1081 did u solve it? ive got the same problem
Cool
VERY AWESOME!!!
Great video.
I thought I was literally copying the video as it went but now I get to debug tomorrow as a learning experience
Me not understanding a bit because I don't know python but still watching because it's interesting
Bro is a menace making a game in Tkinter which is used for making apps
how did bro code get the color picker window for the snake color?
Can you make a c# tutorial and other games we can make?
when i want to make it so that the snake apears back onto the screen when going against a wall how do i do tht? (say i were going right and the snake would collide it would appear on the left again)
You just have to teleport the head coordinate, just add this function to your code, it checks whether we should teleport the snake or not, and also, don't forget to delete the check collisions with the wall from the current code, otherwise they will conflict:
*This is the function:
def check_teleport(snake):
x, y = snake.coordinates[0]
if x < 0:
#Setting the X coordinate to be the other end of the map
x = GAME_WIDTH - SPACE_SIZE
new_coord = (x,y)
#Updating the snake X coordinates to teleportate it to the other end of the map
snake.coordinates[0] = new_coord
if x >= GAME_WIDTH:
#Setting the X coordinate to be the other end of the map
x = -SPACE_SIZE
new_coord = (x,y)
#Updating the snake X coordinates to teleportate it to the other end of the map
snake.coordinates[0] = new_coord
if y < 0:
#Setting the Y coordinate to be the other end of the map
y = GAME_HEIGHT - SPACE_SIZE
new_coord = (x,y)
#Updating the snake Y coordinates to teleportate it to the other end of the map
snake.coordinates[0] = new_coord
if y >= GAME_HEIGHT:
#Setting the Y coordinate to be the other end of the map
y = -SPACE_SIZE
new_coord = (x,y)
#Updating the snake Y coordinates to teleportate it to the other end of the map
snake.coordinates[0] = new_coord
*You should also call it inside the "next_turn" function right above the part that checks if we get the food.
If you are still having trouble, here's the full code for you to test, with this new implementation:

Why do I get IndexError: list index out of range when it runs snake.coordinates[0] ?
Great tutorial!
Please help how to get the white game table on the game tkinter
My snake don't move right every other direction works but if i press right the snake reduces itself to 1 square but after that i can press up/ down and the snake move in the pressed direction
Hello sir, when i run the program it says : " 'snake ' object has no attribute 'coordinates'. "
Please help
how would you make it so that when the snake goes off screen instead of showing game over he reappears on the exact opposite side of the screen that he had originally gone off from?
excellent video!
Thank you teaching
help at if direction == "up":
y -= SPACE_SIZE
it says not defined
I could not do the restart method. Can you help me?
it's so fun and relax
You lessons are very intuitive and ❤’em.. Please can you help me out to create a play again or restart button… I have been trying it for more than three days now but it’s not functioning 😮😮😢.
bro which coding app you using in your pc
Hello. Good day! Can you do a video on how to add menu buttons? Thank you.
