Real Python: Build a Platform Game in Python With Arcade

For many video game players, the lure of writing games is a prime reason to learn computer programming. However, building a 2D platform game such as Lode Runner, Pitfall!, or Super Mario Bros. without proper tools or guidance can leave you frustrated. Fortunately, the Python arcade library makes creating a 2D game in Python accessible for many programmers!

If you haven’t already heard about it, the arcade library is a modern Python framework for crafting games with compelling graphics and sound. Object oriented and built for Python 3.6 and above, arcade provides you with a modern set of tools for crafting great game experiences, including platform games.

By the end of this tutorial, you’ll be able to:

• Install the Python arcade library
• Create a basic 2D game structure
• Find usable game artwork and other assets
• Build platform maps using the Tiled map editor
• Define player actions, game rewards, and obstacles
• Control your player with keyboard and joystick input
• Play sound effects for game actions
• Scroll the game screen with viewports to keep your player in view
• Add title, instruction, and pause screens
• Move nonplayer game elements on the screen

This tutorial assumes you have a basic understanding of writing Python programs. You should also be comfortable using the arcade library and familiar with object-oriented Python, which is used extensively in arcade.

Installing Python arcade

You can install arcade and its dependencies using pip:

$ python -m pip install arcade

Complete installation instructions are available for Windows, Mac, and Linux. You can even install arcade directly from source if you’d prefer.

This tutorial uses Python 3.9 and arcade 2.5.5 throughout.

Designing the Game

Before you begin writing any code, it’s beneficial to have a plan in place. Since your goal is to write a 2D platform game, it would be a good idea to define exactly what makes a game a platformer.

What Is a Platform Game?

There are a few characteristics that separate platform games from other types of games:

• The player jumps and climbs between various platforms on the game field.
• The platforms often feature uneven terrain and uneven height placements.
• Obstacles are placed in the player’s path and must be overcome to reach a goal.

These are just the minimum requirements for a platform game, and you’re free to add other features as you see fit, including:

• Multiple levels of increasing difficulty
• Rewards available throughout the game
• Multiple player lives
• Ability to destroy game obstacles

The game plan developed in this tutorial includes increasing difficulty and rewards.

Game Story

All good games have some backstory to them, even if it’s a simple one:

• The miner in Lode Runner has to collect all the gold.
• Pitfall Harry has to collect thirty-two different treasures in a set amount of time.
• Mario is tasked with rescuing Princess Toadstool.

Your game benefits from a story that connects the actions taken by the player to some overarching goal.

For this tutorial, the game story concerns a space traveler named Roz, who has crash-landed on an alien world. Before their craft crashed, Roz was thrown clear and now needs to find their space ship, fix it, and return home.
