      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.

Unity
stl for C ?

16 posts in this topic

Is there a C equivalent of the STL for C++? I know there wont be an exact equivalent, coz the STL is part of the C++ standard, but is there a stable, accepted library that the community mostly uses? The features I am interested are things like array lists, linked lists, hash tables etc. Thanks!

Glib (http://www.gtk.org) has all of that, and more. It's still tedious to use, mainly because you'll have to do a lot of (unsafe) casting. It's probably better than rolling your own though (more generic). Its a LGPL library.

Hope this helps.

sakky: classes don't have anything to do with libraries. Most languages do have libraries that do not use classes in the C++ sense (and, for instance, O'Caml has a standard library that is approximately as powerful as the STL, but uses no classes in it).

Tylon: while I do not doubt the existence of such libraries, they will certainly be awkward to use because of frequent type casting (as C is lacking universal polymorphism). I do not know of any, personnally. At the risk of sounding a C++ zealot, may I inquire why you must use C only (and not C++) ?

"once understood" being the key words of course. In the mean time, you get to try and avoid undefined behavior, design pitfalls, and the ever-common vague technical reference.

Not to say that C doesn't have it's own minefields, but C++/OOP isn't the panacea most make it out to be.

C++ is a language, OOP is a programming paradigm. C++ happens to natively implement a (limited) version of OOP, but this is the only relationship between the two. OOP does not require fancy "class" keywords in the language to be used, it only requires the existence of a linking step (and I'm not even sure THAT is required). You can do OOP with any language, including C, so it's not legitimate to use OOP as a justification for using C++

At the risk of sounding like a Java (or Smalltalk, or any of a gazillion other languages for that matter) zealot: How is that an argument for C++? [smile]

I actually prefer C#, personally, I was just joking around. I do think that OOP is generally the better way to go, and I think that C is somewhat outdated and is just making things harder than they need to be for... what? Some principle or something that I don't see, I suppose. (And don't tell me 'performance', because most applications don't begin to scratch the surface of what modern hardware can do). Anyway, enough of that rant ;)

C is still the most portable and interoperable language. Nearly every language has C bindings; rarely do you find bindings to other languages. C has sweet simplicity on its side for those who prefer the OOP of CLOS or Smalltalk (dare I even venture to realms outside OOP? Functional programming? Haskell? Scheme? OCaml!?! Heresy!) but have some need to drop to a lower level (speed, foreign libraries, etc.).

Note I'm saying C is better than anything else, just that it has its place. It's quick and dirty for when you need to deal with the nitty gritty under higher level languages.

As for the original question, there aren't many libraries of that sort for C. As mentioned, glib is a good place to look. But why wouldn't C programmers have such a library? Two reasons:

1) They do, it's just a home brew. Back in the day, there was less focus on libraries and so people had to cook up their own. These are perfectly suited to the needs they had, so why would they use some third party library? (If it ain't broke...)

2) As I said, C is an "under the hood" sort of language. (C++ is more like a car without a hood! [lol] Ha! haha... you know I'm funny! err... now you know why I'm anonymous [cool]) General purpose libraries aren't fine tuned for specific purposes. But if you're using C, it's usually because you need something fine tuned for specific purposes.

I like using C sometimes because of the power I feel.

You know, like when you are a sniper, and wear all this gear, and just sit and watch all day. Than you come home, and battle with samuarai swords. You can literally feel the torque of the handle as you swing it. You can count the cycles like you can your heartbeat.

      My game (built on the Unity platform, making use of EZ GUI) requires players to log into Facebook. However, when the player is using a language other than English on Facebook, I'm unable to display the localized Username (which is the same as the FB Username) within the game. Any ideas on how this can be tackled?
      PS: Detecting the OS language doesn't really help here because, for all you know, the player might be using one language for the OS, but another one for their Facebook, so.... 
      TIA!

      Hi there,
      I am a game programmer (C#/C++) who is looking for a project to join. I am computer science engineer plus Master Degree in Game Development, currently working in one the most renown mobile games company (2 years academic experience, 1 year working experience).
      I have developed several prototypes or even games almost ready to release, but I always lack of artists, so I am looking for a project already set up or few artist to begin working in something.
      My preferences are:
      Unity or Unreal Engine 4 based project (UE4 prefered) PC/Console game prefered but mobile is acceptable Not interested in VR Serious team with almost all the roles filled or pretending to be filled 3D project prefered over Sprites Guaranteed 7 work hours per week, Crunch 20 work hours per week  European team (if timezone is not a problem for you, so it is not for me) I am not looking for any kind of money income from games neither the team, I want to do this as a hobby and a way to improve my skills.
