A Complete Guide to Python Game Development | BR Softech TechTricks365

Did you know, many programming languages can be used to code a game? Yeah! This makes it hard for beginner developers to choose one to start with. 

However, if you want to develop a basic game that is not overly complex, you can go with Python. With its easy debugging, easy-to-read syntax, and code reusability, it is a great starter programming language for coding a game. 

In this tutorial, we will go through the step-by-step process of making a game in Python and also explore the various features, benefits, and most popular games developed in Python. 

Is Python For Game Development Reliable?

Before we can talk about the Python game development process, we need to understand ‘Is Python good for game development?’ And the answer varies. 

For emerging game developers, Python is a great starter programming language. Its easy-to-read syntax, reusable codes, easy debugging options, and various useful code libraries make it a preferred choice for new developers. 

In fact, it is commonly used by even large mobile game development companies for game prototyping. This means that your favorite games also use Python for the early stages. Later, on these AAA games are remade in a more scalable and faster programming language like C++ or C#. 

Moreover, some prominent games also use Python for specific elements of the game like scoring or inner logic. 

It is an object-oriented programming language, which has high-level data structures. Python supports dynamic typing in conjunction with dynamic programming binding. 

How to Develop a Game in Python? Step-by-Step Guide

Developing a Python game is not a daunting task, it includes easy steps like idea generation, choosing a development team, pre-production, production, testing, pre-launch, launch, and post-launch. In this guide, we will walk you through making your first 2D game in Python using Pygame, a library made for creating games. 

Step 1: Install Python and Pygame

First and foremost, go to Python.org. Download and install Python (check “ADD PATH” during installation). Next, you will have to install Pygame. Simply, open a terminal or command prompt and run the following command. 

pip install pygame

Step 2: Open a Game Window

Create a new file game.py and add this code: 

import pygameimport sys
pygame.init()
# Set screen sizeWIDTH, HEIGHT = 800, 600screen = pygame.display.set_mode((WIDTH, HEIGHT))pygame.display.set_caption("My First Game")
# Main game looprunning = Truewhile running:    screen.fill((30, 30, 30))  # Gray background
    for event in pygame.event.get():        if event.type == pygame.QUIT:            running = False
    pygame.display.update()
pygame.quit()sys.exit()

Run this command and you will see a window pop up with a gray background. That’s your game world starting to come alive. 

Step 3: Add a Player Character

Now, let’s add a little green square that the player can move with the arrow keys. 

player_x = 400player_y = 300player_speed = 5
while running:    screen.fill((30, 30, 30))
    keys = pygame.key.get_pressed()    if keys[pygame.K_LEFT]:        player_x -= player_speed    if keys[pygame.K_RIGHT]:        player_x += player_speed    if keys[pygame.K_UP]:        player_y -= player_speed    if keys[pygame.K_DOWN]:        player_y += player_speed
    # Draw player    pygame.draw.rect(screen, (0, 255, 0), (player_x, player_y, 50, 50))
    for event in pygame.event.get():        if event.type == pygame.QUIT:            running = False
    pygame.display.update()

Congratulations, now you can move the square with your keyboard. 

Step 4: Add an Obstacle or Enemy

Let’s add a red square or player that will act as the enemy. 

enemy = pygame.Rect(200, 150, 50, 50)
# Inside the game looppygame.draw.rect(screen, (255, 0, 0), enemy)
player_rect = pygame.Rect(player_x, player_y, 50, 50)if player_rect.colliderect(enemy):    print("Boom! You hit the enemy!")    running = False

If the player collides with the red square, the game ends. 

Step 5: Add Scoring

Now, you can also add a scoring system to count how long you survive. 

import timestart_time = time.time()
# Inside the loop, before display.update()score = int(time.time() - start_time)font = pygame.font.SysFont(None, 36)score_text = font.render(f"Score: {score}", True, (255, 255, 255))screen.blit(score_text, (10, 10))

This will add a timer to the screen.

Step 6: Game Over and Restart Option

You can also add a replay and game-over option. 

if player_rect.colliderect(enemy):    print("Game Over")    pygame.time.delay(2000)  # Pause for 2 seconds    player_x, player_y = 400, 300  # Reset position    start_time = time.time()  # Reset score

Additional Tips to Refine the Game

• Replace the square with images using pygame.image.load()
• Add sound effects with pygame.mixer.Sound()
• Create multiple levels
• Add more enemies to make the game more competitive
• Turn it into a full game with a start screen, pause button, and high scores.

Python Game Development Frameworks

Frameworks are a crucial requirement for video game development in Python. Essential game elements like graphics, game, sound, and rendering with the help of Python frameworks. These are open-source platforms that help develop the core functionality of the games. Here are some commonly used frameworks for developing games with Python: 

FastAPI

Fast API is a Python framework that is used to create robust APIs. It offers high-level performance, speed, and efficiency, effectively facilitating the development process. 

CherryPy

CherryPy is an object-oriented framework that allows developers to create web apps. It comes with a multi-threaded web server and can be easily deployed behind other servers like Apache.

What are the Best Game Engines for Python?

Game engines are crucial to developing games in Python. They provide the framework to create and deploy games. Luckily for you, Python supports various game engines, each with its own advantages. Here are some of the best options for game development. 

PyGame: Best for 2D Games

PyGame is one of the best game engines for creating 2D games in Python. This is because it offers all the resources needed to create a simple 2D game including a low-level graphics library. 

While it cannot be used for graphic-intensive 3D games, it is a popular choice for making basic 2D games. 

Panda 3D: Best for 3D Games

If you want to create a 3D game with Python, Panda 3D is an excellent choice. While the core of Panda 3D is written in C++ it supports various APIs that can be called via a Python interface, allowing developers to create a 3D game with Python. In fact, Panda 3D was used to develop Disney’s ToonTown. 

Latest Features of Python for Game Development

Python 3.13 offers a plethora of features and improvements specifically designed to improve the performance, developer experience, and concurrency support. Below let’s explore some more of its features. These features eliminate the hassle in Python game development. 

Features	Description	Benefits
