Welcome to this tutorial! As you probably guessed, the goal is to have a one-stop-shop for all the info you need on how to build a good Roguelike from scratch. We hope you find it useful! But first, some quick Q&A.
Most people familiar with this language will tell you it's fun! Python aims to be simple but powerful, and very accessible to beginners. This tutorial would probably be much harder without it. We recommend that you install Python 2.7 and go through at least the first parts of the Python Tutorial. (Note for Windows 7 64-bits users: install the 32-bits version, since the 64-bits version of Python seems to cause problems with libtcod.) This tutorial will be much easier if you've experimented with the language first. Remember that the Python Library Reference is your friend -- the standard library has everything you might need and when programming you should be ready to search it for help on any unknown function you might encounter.
Version 3.x of Python (version 3.3.0 as of this writing) will not work with this tutorial due to difference with how it handles Unicode strings.
PyPy is a version of Python which can be significantly faster at numerical calculations. This tutorial works with PyPy 1.9, but it's actually slower than 2.7 because we hand off all the heavy duty number crunching like line-of-sight calculations to a C++ library. You might want to consider using PyPy if you write a roguelike which doesn't use a library, but that's outside the scope of this tutorial.
The tutorial uses libtcod 1.5.1. If you would prefer to use version 1.5.0, follow the link at the top of each lesson and code page for the older version.

A (partial, work in progress) C++ port of this tutorial can be found here.

- Part 1: Graphics
- Start your game right away by setting up the screen, printing the stereotypical @ character and moving it around with the arrow keys.
- Part 2: The object and the map
- This introduces two new concepts: the generic object system that will be the basis for the whole game, and a general map object that you'll use to hold your dungeon.
- Part 3: The dungeon
- Learn how to code up a neat little dungeon generator.
- Part 4: Field-of-view and exploration
- Display the player's field-of-view (FOV) and explore the dungeon gradually (also known as fog-of-war).
- Part 5: Preparing for combat
- Place some orcs and trolls around the dungeon (they won't stay there for long!). Also, deal with blocking objects and game states, which are important before coding the next part.
- Part 6: Going Berserk!
- Stalking monsters, fights, splatter -- need we say more?
- Part 7: The GUI
- A juicy Graphical User Interface with status bars and a colored message log for maximum eye-candy. Also, the infamous "look" command, with a twist: you can use the mouse.
- Part 8: Items and Inventory
- The player gets to collect ("borrow") items from the dungeon and use them, with a neat inventory screen. More items added in the next part.
- Part 9: Spells and ranged combat
- The player's strategic choices increase exponentially as we add a few magic scrolls to the mix. Covers damage and mind spells, as well as ranged combat.
- Part 10: Main menu and saving
- A main menu complete with a background image and the ability to save and load the game.
- Part 11: Dungeon levels and character progression
- Let the player venture deeper into the dungeon and grow stronger, including experience gain, levels and raising stats!
- Part 12: Monster and item progression
- Deeper dungeon levels become increasingly more difficult! Here we create tools for dealing with chances and making them vary with level.
Some stuff that is entirely optional and didn't make it in; check this out if you finished the tutorial and are looking for some modifications and improvements to your game -- some are easy, others are more advanced.
- A neat Python shortcut for Notepad++
- For Notepad++ users, how to set up a shortcut to help you debugging.
- Old-school wall and floor tiles
- Using characters in tiles, without getting weird graphical glitches. This is actually very simple.
- Real-time combat
- A speed system to change the tutorial's turn-based combat to real-time!
- Scrolling maps
- Placeholder page for the scrolling map code. Tutorial text will be written soon.
- Creating a Binary
- Package and deliver your game the nice way!

Feel free to stop by the libtcod/Python forum or the forum on this tutorial if you're stuck, to show your own project, or just to say hi! It's always cool to get some feedback on the tutorial, and hear about other roguelikes in development.
