Minimum requirements for game programming

26 May

“I’m interested in learning programming but I’m not sure how or where to start.”

This is an interesting statement, often come across by most programmers on forums, blogs, social media and pseudo-forum sites and most of the time the answer is the same. What I want to do is answer the question from a game programing perspective, firstly to disclose I’m not a professional or a graduate as yet however from my various searches and intrusions and questions asked and read on the above mentioned site I have gathered a fairly complete idea of what is requested. So lets begin leveling up.

Armour – Get the right Hardware

Samus and her trusty Powersuit

Chances are since your reading this that you already have the necessary hardware requirements covered. But if you’re looking for facts and figures this is what I would recommend.  These requirements are future proof so as your skills improve and you start shifting towards more graphically and mathematically complex games you don’t find yourself needing to upgrade your machine to use a more powerful development environment.

  • Computer that has a 1.6GHz or faster processor
  • 1 GB (32 Bit) or 2 GB (64 Bit) RAM (Add 512 MB if running in a virtual machine)
  • 3 GB of available hard disk space
  • 5400 RPM hard disk drive
  • DirectX 9 capable video card running at 1024 x 768 or higher-resolution display
  • DVD-ROM Drive
Most netbooks support these specifications and are a cheap low-cost investment. I would also recommend getting a netbook which can be connected to a monitor (most netbooks already offer this, I think?), preferably one which supports a resolution of 1280 x 1024 pixels.

Weapons – Basic Sword to the ultimate Blade

There are a few ways to tackle programming, the easiest and most direct route would be to learn Python. Python is a simple, dependable and compact language where most complex code is already done for you, it has a few popular graphics libraries (Pygame, Pyglet), which have been tried, tested, taken apart and put back together.  I strongly discourage you to start of in Python, I dislike the language you can read about it here, other than the reasons mentioned in that blog post I feel that Python, particularly in game programming gives a false sense of accomplishment which will cause disappointment as you start to expand your horizons and find that other lower level languages add a new level of complexity.

My recommendation is to start by learning “the C language“, it has a much steeper learning curve but allows you much more flexibility and a wider variety of libraries, game engines and scope if you decide to go professional. It also allows you to branch out to most other popular programming languages like Java, Objective – C, D, C#. It also allows for natural progression to learning and using C++, the professional grade language used by your favourite game programmers or development houses.

Level 01 – Learning C

The easiest way to learn C is to learn by example. Start by taking a book read chapter, do the examples and then the questions and repeat. This is going to be tedious, difficult, and tiring but by the end you should have covered:

  • Variable
  • Loops
  • Functions
  • Pointers (Very Important)
  • Reading / Writing to Files
  • Arrays
  • Structures and Unions

Level 2 – Learning C++

Using the same method as before. You should cover the following:

  • Classes
  • Strings
  • Templates
  • Operator Overloading
  • Function Overloading
  • Exception Handling

Level 3 – Data Structures & Algorithms

Once you get comfortable with Level 1 and 2 your ready to progress to level 3, the most important level in game programming. This is absolutely brutal and probably the hardest part of programming but the most essential, efficiency, searching and retrieval of data, decision trees and many others. Learning a few of these topics wont hurt.

  • Linked Lists
  • Searching & Sorting Algorithms
  • Hash Tables
  • Recursion
  • Trees
  • C++ Standard Library
  • Boost’s C++ Library

Level 4 – Graphics Library

At this point you have a couple of options, you can continue going slow and steady or jumping right in. If you want to continue going slow and steady you can try learning SDL, it’s a basic graphics library that allows you to create 2d games and even simple 3D ones, it is a tried, tested library which is being prepped to work with the iPhone.

The other alternative is moving straight to the meat of game programming and start learning DirectX or Open GL.

The third option that you have is to use a game engine, there are plenty of options depending on your requirements 2D, 3D, Isometric. Engines that have a large user base and well written tutorials are the Unity Engine, Unreal Engine, Panda3D amongst many others.


By this point if you have covered and are familiar with many of the intricacies of a programming language and graphics library and or and game engine your well on your way to becoming a game programmer, the road is hard and difficult but make google your best friend and you’ll be able to bring you ideas to life in no time.

If you have any questions or think that something is wrong do let me know.

Specifications for the Design, Development and Deployment of a Text Based Adventure or SDDDTBA

26 Jan

I spent a large part of January planning this game, and as of writing this the coding has yet to start but I estimate that completing the game will take no more than a few hours this weekend to complete. The chunk of time I spent design the game, the pseudo / actually code scripts and figuring out how to track user events, game events and the flow chart has helped sort out a lot of key problems I would have otherwise had if I used my usual head first method of diving right in making a mess getting an idea of how things should flow scraping work done and starting all over again.

Game Objectives
A text adventure has the beauty of being as complex or as simple as I the designer wants. I wanted to design a game that is follows a fairly linear path and that changes during each play through. Using this idea as my corner-stone I decided that I wanted the game to have two character options, a ranger or a mage, the ranger was a male character and the mage a female one. The game is radically or more accurately subtly different when playing with either character, it is simple things such as the ranger has to complete the game without loosing health and the mage can cast healing spell, or the ranger is capable of dealing and taking more damage than the mage.

The game is subdivided into two main sections, the first section is the Tower where your character needs to traverse the game and save a princess or prince depending on whom you’re playing, this character is intricately woven into the gameplay by being able to provide the player with health and distance attacks if the player is the ranger or a defensive / offensive mover if the player is the mage, the player must not let this character die or will need to start again.

The main trunk of the story will be the same for either character, the only change will be about social interaction between the two characters, hopefully create an emotional connection by the player towards the two main characters.

A simple overview the player enters a magical forest and decides to camp in a clearing for the night and when the player awakens to see a tower that sprouted overnight and being the curious type, they enter the tower.

Setting and Game Play
I’m trying to design the game to be as non liner as possible, or to be more accurate and less misleading, I want the game to be dynamic, the gameplay is dynamic through having different characters with different stats, and most enemies will have more than one method of defeating or getting by.

The Tower
The tower consists of four floors and each floor has something to overcome and an item to collect that may or may not help in the future. The top floor you need to fight the main tower boss and save the character trapped in their.

The forest has been divided into a grid similar to that of a tic tac toe board numbered from 1 to 9, number for each zone will be given at random so that the player will not go through the same path on each play through, however due to time constraints each zone will be fairly linear.

As an additional challenge the player needs to escape the forest with a set limit of time or they will be lost in the forest forever.

Code: Buggy and Hackey
Even though I spent countless hours trying to perfectly plan the game in my head, on paper and in small utility scripts I think all that will go right out the window when I sit down to write it. The game will work but I have a nasty feeling that the code will be ugly and hackey unless I have time to refactor it.

I’m hoping to separate everything into classes, functions, or separate files so that in the future I will be able to reuse the code or atleast the concepts in the code. I’m trying to keep the code as readable (ugly but readable) and forgo trying to make it as efficient as ever maybe someone else can go ahead and do it for me.

The version of Python I have decided to use for this game is Python 2.7 in the IronPython flavour simply because I have yet to see a IDE better than Visual Studio. As of this moment no additional modules are needed or will be used, except maybe for the countdown timer or a curses module for the UI.

Summary or tl;dr
Nothing much to say in all honesty I’m still trying to learn the intricacies of programing and particularly python, so this is a learning experience much more than anything else.

Considering how much time has actually gone and that I have only a weekend to complete I hope that I can complete my specifications and make the game I want.

This is not an excercise in coding it is in completing a game, and in doing so I will write it as hackey as I need to just so that it works.

Gripes with Python

22 Jan

When I started my rather large undertaking to try to complete 12 games in 12 months I took python as my language of choice. I had very little experience in it and wanted to becoming versed in the language and its intricacies by the end of the year.

For January I decided to write a small text-based adventure (specifications will be put up shortly) it seemed to be right up Pythons alley, lots of string manipulations, none to very little data storage and the code is almost script like rather than a complete program because no external modules are used. All my code is kept in a box.net folder along with a python setup executable so that I can access the data and code / debug from anywhere on almost any computer. This setup was perfect for about 2 days when I started to run into various problems.

Gripe 1 – No proper IDE
Before everyone starts chewing off my head, I come from a C / C++ background with a Windows OS. I use Linux (Ubuntu or Fedora) and have love / hate relationship with it, I regularly use the command line for compiling and debugging and often switch between Visual Studio my IDE of choice and Notepad++ when coding. However Python has no proper IDE for Windows that can match Visual Studio for convenience and in my humble opinion quality, it just works and if I’m not mistaken that Python unofficial motto.

Gripe 2 – Whitespace or Tabs
Many people attribute this as a key component for improved productivity. For me however its been nothing but a headache. I’ve been forced to change my entire coding methodology as I can’t move from Visual Studio to Notepad++ with causing some sort of white space error. I spend more time trying to correct syntax errors than actual coding.

Gripe 3 – Lack of Braces
Using braces comes naturally to me because of use in C / C++. Python does not use any while this is not a major problem I find the syntax rather a little difficult to read as I find it difficult to find out where a condition ends particularly when it is multi-lined.

Gripe 4 – Multiple Versions
Python has far too many versions and to use any tool created I need to use a different version of Python or jump through hurdles to print “hello world”. While trying to program games I’m dabbling in the Google App Engine and it requires Python 2.5, I use IronPython in Visual Studio which is compatible with Python 2.7 and when I’m using Pygame or Panda 3D I need to use Python 3+. It is very annoying as each implementation has different syntax and modules are not cross-compatible with Python 2+ and Python 3+, with most not having finished conversion as yet.

Even though I have some genuine problems and irritation working with python I’m finding its community to be very helpful and patient with new users particularly those on r/python.

Code samples are readily available in Python, especially for those looking for large projects that include scaling and other popular buzzwords used today. There are some very interesting projects that are written in Python and following them, editing some of the source is interesting and makes for a good challenge.

It is very easy and very quick to write simple scripts and small utility programs. But only if the modules you hope to use are compatible with the version of python you have installed.

The biggest relief for me was the built-in data structures, I did not have to look for or write my own templated data structures. Along with data structure I find that I prefer Python’s weakly typed arrays, mixing numbers and strings without the use of a custom data structure is a real time saver.

Overall while I’m struggling with the language I’m going to continue using it as it has a lot of scope for the future with its popularity in web app development and game scripting. Hopefully the guys on top sort a few of the language issues and move to Python 3+ and we can all live in peace.

12 Months, 12 Games

2 Jan

Programming requires motivation, and motivation requires an idea that your interested in, and I’m interested in video games. Taking my interests into consideration and to fatten up my portfolio, I’m going to start a second project for 2011, 12 games in 12 months 🙂

Most of what I program doesn’t really interest me or make me want to pick up a new skill or challenge myself. It becomes mundane and everyday. In order to inspire myself and get those creative juices flowing I decided to start this project. The language that I have decided to use is Python 3 and most games will have a text-based gui, or be in 2D using pygame. The source code for the games will be available publicly on my git. One of my goals for is to make these games as casual and accessible as possible, with high replay value.

The games / genres / clones that I would like to make are listed below, I may change some of these around as time goes by removing the less challenging ones.

  1. Text Based Adventure
  2. Hangman
  3. Battleships
  4. Pong
  5. Asteroids
  6. Sidescroller
  7. Shooter
  8. Rougelike
  9. Children’s Game
  10. Racing Game
  11. Tamagotchi
  12. Tetris
  13. Snake
  14. Scorched Earth
  15. Minesweeper

It’s a little more than 12 games but I’m bound to remove a few at a later date. The order might change as well but I’m going to start with the Text Based Adventure.

First Programs I’ve written

8 Apr

Recently, as in today while cleaning up my Code folder I can across a simple Hangman game that I had written a long time ago back when I was just completing my course in C++ and trying to make sense of it all.

Mind you it is very basic and needs a lot of work to make it more efficient and meet the standards required. So without further ado, cast your eyes down upon my very cool code :).

            cout << "\nYou have already guessed " << guess << endl;
            cout << "Enter your guess: ";
            cin >> guess;
            guess = toupper(guess);
        used += guess;
        if(THE_WORD.find(guess) !=  string::npos){
            cout << "That's right! " << guess << " is in the word." << endl;
            for(int i = 0; i < THE_WORD.length(); i++){
                if(THE_WORD[i] == guess)
                    soFar[i] = guess;
            cout << "Sorry, " << guess << "is not in the word." << endl;
    if(wrong == MAX_WRONG)
        cout << "GAH!! GUH! NOOOOOooooooo\n Your hanged : ) HAHAHAHA" << endl;
        cout << "\nYou guessed it : ) Your awesome." << endl;
    cout << "\nThe word is " << THE_WORD << endl;
    return 0;

There you have it folks, enjoy.

Please feel free to use my code, just make sure I get credit or at the very least let me know whose using it.

Get into Game Programming

10 Nov

Information, especially finding good information takes time and patience especially since it is spread all over the internet, creating and maintaining a list of this is hard and extremely time-consuming. This guide attempts to educate you in-game programming, how to start, what to do and eventually how to break in and build a portfolio.

About Game Programming
The games industry, is a very profitable, very competitive industry. It has very high barriers to entry, because it is a very difficult field. Programmers are constantly learning and becoming fluent in programming languages, scripting languages, game engines, graphics engines, tool kits, directx, opengl, openal, ai, various API, SDK’s, methodologies, math etc. By keeping the barriers at such a hight they manage to separate the motivated (ie. those who want to get in) and those who just feel like it (ie. those who think its cool, easy or are just lazy). A few things that you should know are the long stressful hours through out development and more so during milestones and crunch time, salaries are also not high by comparison to other fields of development.

But it has its advantages, programming games is very cool and a lot of fun and like me I’m sure other programmers hobbiest or professional get that happy, fuzzy feeling when they see something they created being played and enjoyed by others. It is also a very dynamic work environment where you are surrounded by like-minded, smart and creative people, the work itself is challenging and no two problem are the same. More importantly these people will get that obscure Star Wars or Doctor Who reference 🙂

How to Start
At the heart of any game is the engine, which does the herculean task of rendering images and processing input. To have any interactivity at all you need to know how to program.

Which Language should I use?
You have countless choices of programming languages to learn for a variety of platforms, fortunately these languages all quite robust share common elements, learning one means that you can quickly pick up and learn another in a relatively short time.

I have adopted a five star system where one is the easiest and five the hardest, these are my opinion and I have tried to make them as beginner friendly as possible.

Compiled Languages
C ****
Regarded as many as the greatest of modern programming languages, It is very robust and portable, the same code can be ported to Linux or Windows with very little changes being made. It has a community online whom you can get help from and countless tutorials and lessons. You have access to thousands of libraries written over the last 30+ years that will make life easier. Used to be the industry standard.

C++ *****
This is the industry standard today, it is used in almost all major platforms from the PC to the Pandora. As a result of its wide spread use it is a very powerful language that is a superset of C, as a result you have access to thousands of libraries written for C and the thousands more written for C++, can write extremely portable and reusable code thanks to Object Oriented Programming features such as data abstraction, encapsulation, polymorphism, and inheritance. Unfortunately it is not one of the easier languages to learn.

Java ***
Java is a strange language it is not exactly a compiled language and nor is it an interpreted language.
I’m not entirely familiar with and nor am I fond of Java and this may colour my opinion. It is a very powerful language but its scope in-game development so far has been extremely limiting, however it is used for a lot of web-based games, applets, mobile applications and the Android OS contains sections of code written in Java. It is not very difficult to learn in fact John Carmack suggested that beginners start learning programming using Java, as you can immediately start making simple 2D games, but unless utilized properly it is very slow.

C# ***
This is Microsoft response to C++, it is a very robust language and you can port your game from the Xbox 360 to the PC or vice versa with almost no trouble. It is a fairly easy language to learn and also integral to the industry. You also have access to XNA framework which is used by companies to make Xbox Live games. You can easily create Windows applications with speed and without hassle compared to the other languages.

Interpreted Languages
Python **
Python is a hybrid, an extremely powerful language with EVE Online being coded entirely in Python, Civilization 4 also has python bindings as a part of it to allow the mod community to easily modify and create for the game. In my opinion python has not exactly found its place in the industry because it can do so much, but common uses for it are in scripting and indie gaming.

Lua **
I have never used Lua so I am unable to judge it, but from what I read and the few tutorial I checked out, it is not very hard to learn and a very strong scripting language.

Order in which to learn
This is by no means the best order to learn the languages, but it allows you to get familiar with the concepts of programming and the methodologies without getting bogged down and hopefully motivate you to pursue the other.

1) Python
2) C
3) C++

I have not included Java, C# as you can study those after you master the languages above. Java and C# have been excluded particularly because they were created to make the developers life easier tend to lull beginners into a false sense of security as a lot of the backend and low-level development is hidden. While this has its positives in the hands of an experienced programmer in the hands of a beginner it can cause all sorts of headache and code bloat. There is a reason that C++ is the industry standard not just in games but also in various fields of software development because of its low-level access.

Lua is not mentioned as until you have knowledge on programming you wont know how to include it in your game.

A word of warning though, once you learn the three languages above you still have a very long way to go before you can make a full 3D game or even a 2D one, most of the code you will write in the beginning will only run on the command line. But don’t fear once you master the basics you can advance to the fun stuff.

Which Books should I read?
The following is a set of Books that I have read, No review is given just how easy is it to follow, also most of these are not about game programming they are about learning the language.

Language Title Author Ease of Use
C How to program in C Dietel *
C The C Programming Language Kernigham & Ritchie ***
C++ Accelerated C++ Koening & Moo ***
C++ The C++ Programming Language Stroustourp ****
C++ Beginning C++ Game Programming Dawson **
C++ Thinking in C++ Vol. 1, 2 Eckel ***
Python Learning Python Lutz *

Which Online tutorials should I follow?

In all honesty it is better to follow a book rather than a tutorials as it may lead to shortcuts and bad habits, but a few that I check out are:

Language Website
Various http://www.functionx.com
C/C++ http://www.cprogramming.com
C++ http://www.cplusplus.com

I N33dZ t3H h3lP?!!@??
First off, never start a forums topic like that, your going to get banned. Secondly read this.

The best forums for programming help are:

In the next few days I will add information on game engines that will be a natural progression to what you’re learning and a proper list of web resources.

Feel free to comment, question, suggest or criticise.

Programming Challenge: Battle Ships

14 Mar

I have been studying programming for about a year now and want to challenge myself to see how much I know and still need to learn so I decided to make a small game based on battle ships.

Its going to be a fairly simple console based version to which I am hoping to add features and functionality as I learn more and more.


  • Written in C language to be ported later to C++ or C# and made a console program
  • Should display the screen using X
  • The ships will be displayed using DDDD for destroyer, and be allowed to place vertical or horizontally
  • Basic battleships rules apply
  • It will have single player initially and hopefully multiplayer on both the same machine and over a network
  • Cross platform compatibility on Linux and Windows
  • Specs maybe changed or updated at a later date
