      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.

Yes, that's exactly what I'm doing now, except I didn't remove the dynamic allocation part though (will probably do that later), but now it looks like this:


int main( int argc, char* argv[] )
    game_app_t* app = new game_app_t();
    return 0;


The pointer does get deallocated upon exiting because I used a function pointer passed to atexit() to ensure everything is released.


If that's also a bad idea, feel free to say so.  I do appreciate everyone's advice.  I'm learning something new from every response, and that's why I'm not afraid to make dumb threads! smile.png



Dude please, stop programming C++ stuff and pick a book or read some of the C++ faqs or the new approaches about C++11, but you are programming like if you were doing a thing between Java and C.


I learnt C++ years ago too, but one month ago when I backed to do C++ stuff I knew I had horrible bad practices and I had to solve them, so I just picked a quick summary comparing old C++ with C++11, together with the faqs are linked in this thread and I achieve to get a big knowledge about the language itself.


I know I still have some problems which usually they are design related, but at least I don't have serious problems with stack/heap memory or using macros (language stuff related).

While I concur with looking heavily into C++11 features, and with studying when to use dynamic memory and when not to, I don't think he should stop programming C++. Learning is half study and half practice.

I've wrote lots of dumb pieces of code - unless you're taught by another programmer (which I wasn't) who happens to be very skilled, you can't code perfectly right away, you learn better and better practices continually. Or, at least, eight years later I still am tweaking my practices when I discover better ways of doing things. When I first started out, my code was horrible. But you grow through usage.

@blueshogun96: Here's a practice tip, if you want one:
Write your program without using any 'new'/'delete' (or 'malloc'/'free', or similar functions). Don't use smart pointers either (for practice).
Declare everything locally, or as member-variables of a local class. This removes globals, and it removes dynamic memory. Things like vectors and maps are perfectly fine though.

Once you finish a project like that, then in future projects when you *need* to use dynamic memory, use smart pointers instead of new and delete.
