Thank you for this tutorial. I found it useful and clear for beginners. Following your tutorial, I wrote my first game. Not too simple, not too difficult. The golden average of complexity with nice comments. Thank you.
A great tutorial, I am planning to use this for my Digital Tech students as it is so clear and I feel I would be reinventing the wheel to try and make my own, I hope they send you many likes.
Impressive tutorial, good visualization, good sound, excellent explanation that I have seen with subtitles in Spanish. And everything explained step by step, thank you very much for all the time invested in this wonderful tutorial, I am looking forward to seeing the next one. 👍
This is by far the best tutorial for this type of content Ive seen so far on youtube. Im just randomly wanna see how other people code, it makes my mind relax after long hours of coding at work lmfao Ironic.
I have just completed your tutorial and I want to Thank You a Lot... easy to follow, a lot to add to my new python brain and perfect for keeping experimenting.. Thanks a lot.
An amazing tutorial, very useful. But I was running into a problem detecting collision between the food and the snake. This is my code: # Update Function- updates the game def update(self): self.snake.update() self.check_collision_with_food() # Collisions / eating def check_collision_with_food(self): if self.snake.body[0] == self.food.position: self.food.position = self.food.generate_random_pos() when the snake would "eat" the food it wouldnt do anything. the snake will just hover over the food and not eat it. pls help!!!
I first want to TYVM for this tutorial. But I can't seem to get a game over text to appear I have it defined like we did the title and score but when game_over() no text appears I was trying to write GAME OVER then under it PRESS ANY KEY TO CONTINUE. also I tried to put some music so it not so quiet I got the music to play but it so loud you can;t hear the other 2 mp3's I tried the volume(0.1) but it did not seem to work it was still the same sound level as I never use that part of code could you maybe do an extra chapter for this game with what I was trying to implement?
Hi. I am having position attribute error on line 17… food_rect =pygame.Rect(self.position.x*cell_size…) o don’t understand where this error is coming from. Position is a reference to self.position =vector2 (5,6)
Hi. Very nice tutorial. I noticed one thing. Lets say snake is moving to the right direction and if you press quickly down followed by left arrow then snake will change direction straight from right to left. Curious how would you fix that bug ?
The solution is to introduce a queue to store the direction changes and process them one by one. This approach will ensure that the snake doesn't change direction immediately but rather processes each direction change in the order it was received. here is the updated code : import pygame, sys, random from pygame.math import Vector2 pygame.init() title_font = pygame.font.Font(None, 60) score_font = pygame.font.Font(None, 40) GREEN = (173, 204, 96) DARK_GREEN = (43, 21, 54) OFFSET = 75 cell_size = 30 number_of_cell = 22 food_surface = pygame.image.load(r"graphics/food.png") class Food(): def __init__(self, snake_body): self.position = self.generate(snake_body)
def generate_random_cell(self): x = random.randint(0, number_of_cell-1) y = random.randint(0, number_of_cell-1) return Vector2(x, y) def generate(self, snake_body): position = self.generate_random_cell() while position in snake_body: position = self.generate_random_cell() return position
So, new position of food is simply random? It's ok in the, lets say, first half of the game. But when snake will grow really long, what then? Imagine the situation when snake is 615 tiles long and there is only 10 free blocks. For how long program will hang on the function food.generate_random_pos? And it will be worse with each eaten food.
Hello you are right. This solution is not the fastest but it is the easiest. In worst case schenario, the while loop will take around 1ms, so it won't be noticeable don't worry. We update the snake's position every 200ms for comparison. Of course you are free to use a more elegant solution.

Thank you very much for your feedback! I am glad that my work is helpful, it takes a great amount of time to produce these tutorials!
Thank you Nick for your tutorial, clearly the best one on this topic one could find! You are a great teacher. Well done!

Thank you very much for your kind words. It means a lot to me!

Best tutorial out there, very underated content...
This is the best TH-cam channel for beginners🎉
Nick, this was great. Thanks for helping me better understand Pygame and OOP!
Wow, thank you very much!! I am glad my video was helpful. Your supports really helps!
Thank you for making the subtitles.
I just love your tutorials. You are great
Very good tutorial. Thank you for sharing.
BRO GOOD CONTENT❤I like your video DO PLEASE More video because its really good❤

pygame does not work well with mp3s. Try converting your sound files to .ogg to see if that helps.
Hi. I am having position attribute error on line 17… food_rect =pygame.Rect(self.position.x*cell_size…) o don’t understand where this error is coming from. Position is a reference to self.position =vector2 (5,6)
supposed to be Vector2 (5,6) instead of vector2 (5,6)

How can i downlaod the same image of food as yours?
