      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      GameDev.net and CRC Press have teamed up to bring a free ebook of content curated from top titles published by CRC Press. The freebook, Practices of Game Design & Indie Game Marketing, includes chapters from The Art of Game Design: A Book of Lenses, A Practical Guide to Indie Game Marketing, and An Architectural Approach to Level Design. The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development. We know game development can be a tough discipline and business, so we picked several chapters from CRC Press titles that we thought would be of interest to you, the GameDev.net audience, in your journey to design, develop, and market your next game. The free ebook is available through CRC Press by clicking here. The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

Made a few decisions (Update)

Well so far I made a few decisions and was able to get some basic code up and running to test the environment.

The first decision I made was to use C++ over Python and other languages I know. The main reason for this decision is library support. When I look from the perspective of game development with Python there are libraries that exist and they are wrappers around C/C++ libs. This is not an issue but the issue does arise with the way they are wrapped in many cases using Cython. I do not know much about Cython but what I do know is you really need to pay attention to the compiler you use with Python and wrapped libraries otherwise you get tons of crashes. I really did not want to go with this hassle I would much rather bolt Python or Lua on top of my code before going through all the setup required.

Now that this is out of the way I also decided to go with SFML-2.1. This is really a no brainer due to my decision to use C++. This is a super clean library and there is very little to complain about. It handles many parts you do not want to handle and stays simple enough to not step on your toes where you do not want it.

As far as IDE's and Compilers go I really wanted to stay away from VC++. Do not get me wrong here it is a great compiler and IDE but I do not spend all my time on Windows anymore. The main reason I use windows is because it is required for school, however, after I graduate this summer this is not a deal breaker for me anymore and I am likely to go to Linux full time for the most part and just leave Windows laying around for cross platform testing purposes. Due to this I decided to go with QTCreator with mingw_w64 32bit. The version you get with QTCreator 2.8.1 uses GCC 4.8.1. This is really a very nice IDE so far I have only used it a small amount but it is really indeed slick to use.

Also from what I can see qmake is very powerful and well designed and not too difficult to figure out. Qmake is basically similar to something like CMake in the respect that it does not actually build the code but instead it is a makefile generator to create the makefile for you.

So with all this set up I was able to put together what I would consider the SFML Hello World application which they use in the documentation to demonstrate how to setup the library.

The purpose of the code is to create a colored circle on the window rendering surface which is quite simple.
#include int main(){ sf::RenderWindow window(sf::VideoMode(200, 200), "SFML Works!"); sf::CircleShape shape(100.0f); shape.setFillColor(sf::Color::Red); while (window.isOpen()) { sf::Event event; while (window.pollEvent(event)) { if (event.type == sf::Event::Closed) window.close(); } window.clear(); window.draw(shape); window.display(); } return 0;}
Very simple. Create the window, add the circle of a particular radius, start the event handler, and exit when closed.

In order for this code to compile you obviously need to add the includes, and libraries to the project. QTCreator does this differently then most ide's as it is not done through the configuration ui it is actually done in the project file aka the .pro which just so happens to also be your QMake file as well. This is really cool :D

The other issue is I am dynamically linking to SFML instead of using static libs. So the dll files must be present. In my opinion the typical way of copying the dll files in place by hand is annoying. To automate the process is platform dependent and QMake again comes to the rescue by allowing to create a unix or a win32 block to cover platform dependence. With this I can manipulate the directories and pipe the information into cmd.exe to copy the dll files to the build directory. Really neat stuff.

Here is the .pro file for qmake with comments. The thing to note from a windows perspective this can only be run from the ide. The reason it cannot be run from the debug folder in this case is although I can copy over the appropriate runtime dll's for dwarf2 and pthreads; I cannot copy over libstdc++'s dll. I am not sure why I think the way the file is named causes the terminal copy command to croak. If anyone knows a better way please let me know as -static-libstdc++ seems to not be statically linking like it should.TEMPLATE = appCONFIG += consoleCONFIG -= app_bundleCONFIG -= qtINCLUDEPATH = c:/libs/SFML-2.1/includeLIBS += -Lc:/libs/SFML-2.1/lib -lsfml-graphics -lsfml-window -lsfml-systemSOURCES += main.cppwin32:debug { EXTRA_BINFILES += \ c:/libs/SFML-2.1/bin/sfml-graphics-2.dll \ c:/libs/SFML-2.1/bin/sfml-window-2.dll \ c:/libs/SFML-2.1/bin/sfml-system-2.dll EXTRA_BINFILES_WIN = $${EXTRA_BINFILES} EXTRA_BINFILES_WIN ~= s,/,\\,g # regex replace '/' with '\' in path list DESTDIR_WIN = ./debug DESTDIR_WIN ~= s,/,\\,g # regex replace '/' with '\' in the path # iterate through file list and copy to the build directors for (FILE, EXTRA_BINFILES_WIN) { QMAKE_POST_LINK += $$quote(cmd /c copy /y $${FILE} $${DESTDIR_WIN} $$escape_expand(\n\t)) }}
That is all for now hope you enjoy.
