Are you a fan of classic arcade games? Maybe you’re looking to improve your Python skills? Well, why not combine both by making your very own snake game in Python! This tutorial will take you through all the steps needed to create a fun and addictive game that will have you slithering for hours. So, put on your coding hat and let’s get started!
How the snake game works
Python has a built-in module called ” graphics ” that you can use to create games. To create a snake game in Python, you first need to create an object of the class ” snake “. This class defines the properties and methods necessary to play the game.
Next, you need to define the position of the snake on the screen and how long it will take for it to move. You also need to specify how fast the snake moves and how many times it can turn around. Finally, you need to define what actions the player can take: moving left or right, advancing toward or away from the center of the screen, and so on.
When you’re finished defining these parameters, you can start creating functions that will carry out these actions. The first function is called ” start “, and it sets up all of the necessary variables for playing the game. It also starts the timer so that we can track how long it takes for the snake to move.
function start() { // Setup all of our variables var w = 800, h = 600; var size = (w + h) / 2; var speed = 3; var lives = 5; // Initialize our Snake object var snake = new Snake(); }
The next function is called ” update “, and it’s responsible for updating all of our variables as necessary during gameplay. This includes updating how far along the snake is on its path, adjusting its speed according to how much movement has been
Importing the modules
So you’ve decided to make a snake game in Python. Great! In this tutorial, we’ll show you how to import the necessary modules and get started coding.
First, we need a module for handling sprites. We can find one here:
https://github.com/pygame/pygame/blob/master/modules/core/skinsuits.py
Next, we need a module for handling maps. We can find one here:
https://github.com/pygame/pygame/blob/master/modules/core/maps.py
Now that we have our modules ready, let’s start coding! First, we need to create an instance of the Sprites module and add our snake character to it:
import pygame as pg import time class Snake(object): def __init__(self, x, y): self.x = x self.y = y #create the sprite object sprite = pg.Sprites.Sprite() sprite.position = (self.x, self.y) #render the sprite object pg._render(sprite) #update the screen every 1 second clock = time .time() if clock – last_update > 1000 : print(“Wake up!”) last_update = clock def last_update(self): global clock if self == pg._gameState: #reset everything pg._
Creating the game’s screen display
When creating a game, it is important to think about how the player will see the game’s screen. One way to do this is to create a graphics file that can be used as the game’s background. To create a graphics file for our snake game, we will use the PIL library.
To start, we need to create a new image file. To do this, open up a command prompt window and enter the following code:
pil = Image.open(“snake.png”)
Next, we need to resize our image. To do this, enter the following code:
pil.resize(500, 500)
Now we can save our image using the following code:
pil.save(“snake.png”)
Setting up the direction keys for the snake
To set up the direction keys for the snake, you will first need to create a function that gets the current position and direction of the snake.
def get_direction(self): x, y = self.position() d = (x[0] + x[1] * 100) % len(x) # remap 0-100 index to -32768 to make range -2**32 to 2**31 return d
The snake game gameplay implementation
In this blog post, we will show how to create a simple snake game in Python. We will be using the Tkinter library and the pygame library. The game will be made to run on an Android device.
To begin, we need a window object. We can instantiate this object by calling the tkinter import function and passing it the name of the window class that we want to use. In our case, we will use the tkinter window class named “Window”:
import tkinter as tk
Next, we need to create our main event loop. This loop will be responsible for handling all user input and updates to our game objects. We do this by creating a new instance of the tkinter event loop object and setting its poll() method call handler to our window object:
global mainEventLoop : mainEventLoop = tk . Tk ()
Next, we need to create our snake game object. This object will contain all of our game logic and graphics. We do this by calling the pygame module’s constructor and passing it two arguments: a width and height parameter which define the size of our game screen, and an image filename containing our snake graphics file:
snake = pygame . init ( 800 , 600 )
We next need to set up some basic variables in order to keep track of things like player position, snake length, etc.:
width = 800
Conclusion
In this tutorial, we learned how to make a snake game in Python. We started by creating a simple game loop and adding the mechanics for moving the snake and controlling its direction. We also created a function that allows us to render the snake on the screen.
We then added the necessary code to create a player object and create an instance of it in the game loop. The player object contains methods for moving and manipulating the snake, as well as rendering its position on the screen.
Last, we added some code to handle user input and respond to events that occur during gameplay. We closed out our project by displaying some final information about our game and providing a link to download it.
