MasterList = 'a'ĭrawTheBoard(appleX,appleY, positionSnakeX, positionSnakeY,lengthSnake) PositionApple = random.randrange(0, 580, 20) #code for press enter to continue using draw package and keys MasterList = for row in range(30)]ĭraw.string('CLICK ANYWHERE TO CONTINUE',30,330) For example you could change some colours, or the speed of the snake, or the controls etc.Currently working on designing a snake game using python, with import.draw, without pygame! Most of my game is completed and it is working out very well, except for the fact that any time an arrow is clicked( up,down,left,or right) the length of the snake just becomes bigger, that is not what i want to happen, because the length should only become larger once the snake eats the apple! Whatever your level, you should experiment with the code, play with it. Y = random.randint(- HEIGHT / 2 + FOOD_SIZE, HEIGHT / 2 - FOOD_SIZE)ĭistance = ((y2 - y1) ** 2 + (x2 - x1) ** 2) ** 0.5įood.shapesize(FOOD_SIZE / 20) # Default size of turtle 'square' shape is 20. X = random.randint(- WIDTH / 2 + FOOD_SIZE, WIDTH / 2 - FOOD_SIZE) Snake.pop(0) # Keep the snake the same length unless fed. # No self-collision so we can continue moving the snake.

If new_head in snake: # Or collision with walls? # screen.update() Only needed if we are fussed about drawing food before next call to `draw_snake()`. Global snake, snake_direction, food_pos, pen ''' A simple snake game using Turtle Graphics. Depending on your level of experience, you may be able to understand exactly how it works or maybe just some of it. The basic movement of the snake can be implemented in a simple program as shown here: import turtleįor info on using the super-handy stamp() function of Python Turtle Graphics, check out my video on YoutubeĪs an Amazon Associate I earn from qualifying purchases. Ta da the snake has moved forward one position! Moving the Snake with Python Turtle Graphics Finally, remove the leftmost item ( s1, or ), using snake.pop(0).Increment the x coordinate of new_head, giving. Must be copied or original would be modified by next step. New_head = py() # snake means the rightmost item. create a new list item for the new head position:.NB For this demonstration, consider the leftmost list item to be the tail and the rightmost to be the head. These are the steps for the second version: Create a copy of the head, add it to the front of the snake and then chop off the last segment.Chop off the last segment, and add it to the front of the snake each time the snake “moves”.Here are two ways to conceptualize what is basically the same effect:

The main challenge is how to get the snake to move. There are several ways to approach programming the Classic Snake Game in Python (or other languages for that matter). We could use sn to notate the nth segment: We represent our snake as a list of pairs of coordinates: Python Snake Game Program Explained Snake Representation The Python Turtle module is built on Tkinter and some commands are not available in the standard Turtle There is a post on this blog about the Turtle Graphics demos which come with IDLE (the development environment that ships with Python) – check them out to get an idea of some of the fun stuff you can do!īelow is an embedded version of the Classic Snake Game on Ĭlick on the Turtle window to enable keyboard control using the arrow keys. Python Turtle Graphics is awesome! It can be used to learn and teach Python programming and Computer Science from elementary to advanced level.
