python browser based game development

Everyone these days loves playing games. From children to people of old age, everyone is glued to their gaming devices to have some fun and refresh their minds. As a result, the gaming industry is flourishing by day and night. According to Forbes, the gaming industry will reach over $300 billion by 2025.

The web is a growing platform to host online browser-based games that users can play from anywhere and anytime around the world. Gone are the days when web-only supported plain old 2D based games. Now, with the growing technology, you can create exciting graphics-rich online games.

Honestly, Python is not so popular when it comes to developing resources intensive gaming applications. Developers usually complain related to the performance of games built on top of Python. However, it is not the case when it comes to creating browser-based Python games. There are many web technologies and Python libraries and platforms which you can use to create graphically rich games that run on most modern-day browsers.

In this article, we will see discuss various ways and tools to make a web game in Python. With these tools, you will be able to build a game that runs on any modern-day browser.

Before getting started, let’s first see why you should target the online browser games market.

Why Should You Target Online Browser Games?

People love to play mini-games on their browsers. You will probably find browser-based games on almost every genre from FPS, RPG, Arcade, to city building, war games, and so on. Therefore, if you learn how to create develop browser-based games, then you can earn some handsome amount of money as well.

Other reasons include:

  1. The web has infinite reach, and the games built for web browsers work well on most platforms such as PCs, smartphones, tablets, etc.
  2. Improved discoverability of your browser game as you can benefit from the shareability and linkability of the web.
  3. All revenue from your mobile game is yours, and you don’t have to pay any portion of your income to app stores.
  4. Your users can play your game from anywhere and anytime. All they need is an internet connection to play your browser-based Python game.
  5. Better engage with your game players to get feedback without any middleman.

The Role of Python in The Gaming Industry


  • The AI behavior of The SIMS is scripted using Python.
  • The map editor of Civilization IV supports Python programming.
  • Another popular game that supports Python is Disney’s Toontown Online, which is multiplayer online role-playing (MMORPGs). It helps pandas3D for graphics of the game, and the game is quite lightweight.
  • EVE Online is another MMORPGs who is using stackless Python – a variation of Python programming language for its client and server-side code.
  • Battlefield Heroes uses Python for some parts of their game logic, such as scoring with cleartext and game modes.


How To Use Python For Browser Games Development?

Primary browser games utilize JavaScript and WebGL or Canvas2D for displaying graphics on the browser. There is no way to build your entire browser game using Python as web browsers use HTML to render web pages and its various elements. Therefore, you can use Python for the backend logic of your game and render it as pure HTML on browsers.

Another way is to use Python on the backend to generate interactive Flash or JavaScript to run on the browser.

Popular game engines such as Unity3D or UnrealEngine gives you the option to export game projects into a compatible HTML5 code. However, this method is quite complex and time-consuming to implement inside a game engine.

The best way is to use any native HTML 5 game engine. Using a native HTML5 game engine, you can produce optimized JavaScript code, which will also boost the performance of your browser-based games.

Let’s get down to the nitty-gritty of Python-based browser games. You have to use frontend technologies and APIs to render your game on the browser and use Python gaming libraries and frameworks at the backend for determining gaming logic.

Technology for browser-based Python game development

1. Full Screen API – If you want your browser game to run over the entire screen.

2. Gamepad API – For providing gamepads or other game controllers support to your browser game.

3. Web Audio API – Games without audio are pretty dull, and no one would like to play it. Use Web Audio API for controlling playback and manipulation of audio from JS code. You can add cool sound effects and apply them in real-time.

4. HTML and CSS – Most important to learn if you want to build your own browser game. Using HTML and CSS, you can design the interface of your browser game. <canvas> HTML tag provides an easy way to do 2D graphics.

5. JavaScript – Modern-day programming language of the web, which is fast. Using it, you can apply Python logic from the backend to control the gameplay.

6. HTML Audio – If you only require basic audio for your browser game, then you can simply apply the <audio> HTML element.

7. WebGL – Create high-performance and hardware-accelerated 3D and 2D graphics from web content.

8. WebRTC – WebRTC or Web Real-Time Communications API supports the transfer of video and audio data, including teleconferencing back and forth between multiple users. So, if you want to build an online multiplayer game and allow players to talk with each other while they are busy killing zombies, then this the API for you.

9. WebSockets – Connect your browser game to the server and facilitate real-time data transfer to support gameplay actions, chat services, and so on.

1o. Web Workers – Take advantage of modern-day multicore processors using Web Workers. Spawn background game threads running their own JS code to enhance the performance of your Python-based online game.

11. Pointer Lock API – Get exact coordinates of your user’s cursor to do accurate measurements of what players are doing in the game.

Now, that you are familiar with various web technologies that you can use for online Python game development. Let’s see various Python libraries and frameworks for game development.
