      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.

OpenGL
Understanding whats going on

7 posts in this topic

So I have a little bit of programming and engineering experience. I am trying to figure out what's going on here. I would like to use an open source compiler to compile opengl code. I would just like the knowledge of libraries and pre-processor header files and how they work. I am looking at opengl code and I see that I can use some header file and not others. I am working with the supper bible series 1-6. I am looking at the header files and I can see that I can compile with gcc with some header files and not others. I am starting from the first book of the supper bible series and seeing what I can compile. I know I can compile most code up to 3.1, then I can't work with any of the libraries. I know that a lot of the code has depreciated and is not forward compatible, this is what is making it very difficult for me because I have to see where I can start from. If anyone can please explain to me what is going on here I would really appreciate it.

I can use these four header files and anything after that doesn't work with a gcc compiler 

 

#include <GL/glew.h>
#include <GL/gl.h>
#include <GL/glu.h>
#include <GL/glut.h>

GLTools.h isn't a standard header file with any compiler - I guess it's something specific to the author of the super bible books. You can probably download the source for the books (at least you usually can) which should have the header included...

 

However, I suggest that you don't rely on someone else's proprietary include files for the simple reason that it may mislead you into believing that it is something to do with GL. Beyond that, I can't say as I've never read those particular books.

Can I ask why you don't want to use Visual Studio? The premier versions are exquisite , and the free versions are excellent! Better than anything else on the market (in my own humble opinion).

 

If you've been led to this dislike of VS by a tutor, I'd strongly recommend ignoring those opinions. VS free edition, with all it's faults, is pretty damn good.

Umm i just don't like to be tied down to one compiler and I want to know what is going on behind the scene. Learning how to do this has taught me a lot about how to add folders with header and library files. I have found out how dynamic link libraries and static linked libraries work, and how to add multiple files to project. All using a command line. It's really my instructor got me going down this route. He says that MSVS express has a date on it and they could tell everyone to just stop using it, please this is not politics, that they might just start charging everyone and it would be very difficult transition and its just better to know how everything is really working.

That's not even remotely true.  The Express editions are and always have been "free permanently" (that's "free as in beer").  There are plenty of online references to support this - e.g http://blogs.msdn.com/b/rprabhu/archive/2006/04/21/580446.aspx - you should ask your instructor for a reference to support his own claim.

 

Wanting to have experience with multiple tools is good, but VS is very much an industry standard, so you should include that in the set of tools you get experience with.

      For this goal, the MyShapes class will be responsible for defining shapes such as triangles, polygons etc. Currently, there is only a drawTriangle() method implemented, because I first wanted to see whether it works or not before attempting to code other shape drawing methods.
      The constructor of the MyEngine class creates a GLFW window (GLAD is also initialized here to load all OpenGL functionality), and the myEngine.run() method in Main.cpp is responsible for firing up the engine. In this run() method, the shaders get loaded from files via the help of my FileHandler class. The vertices for the triangle are processed by the myShapes.drawTriangle() method where a vertex array object, a vertex buffer object and vertrex attributes are set for this purpose.
      The while loop in the run() method should be outputting me the desired red triangle, but all I get is a grey window area. Why?
      Note: The shaders are compiling and linking without any errors.
      (Note: I am aware that this code is not using any good software engineering practices (e.g. exceptions, error handling). I am planning to implement them later, once I get the hang of OpenGL.)

      Hey guys, whenever I call SwapBuffers(hDC), I get a crash, and I get a "Too many posts were made to a semaphore." from Windows as I call SwapBuffers. What could be the cause of this?
      Update: No crash occurs if I don't draw, just clear and swap.

      Hey devs!
       
      I've been working on a OpenGL ES 2.0 android engine and I have begun implementing some simple (point) lighting. I had something fairly simple working, so I tried to get fancy and added color-tinting light. And it works great... with only one or two lights. Any more than that, the application drops about 15 frames per light added (my ideal is at least 4 or 5). I know implementing lighting is expensive, I just didn't think it was that expensive. I'm fairly new to the world of OpenGL and GLSL, so there is a good chance I've written some crappy shader code. If anyone had any feedback or tips on how I can optimize this code, please let me know.

      Hi,
      Not sure to post at the right place, if not, please forgive me...
      For a game project I am working on, I would like to implement a 2D starfield as a background.
      I do not want to deal with static tiles, since I plan to slowly animate the starfield. So, I am trying to figure out how to generate a random starfield for the entire map.
      I feel that using a uniform distribution for the stars will not do the trick. Instead I would like something similar to the screenshot below, taken from the game Star Wars: Empire At War (all credits to Lucasfilm, Disney, and so on...).

      Is there someone who could have an idea of a distribution which could result in such a starfield?
      Any insight would be appreciated

      I have just noticed that, in quake 3 and half - life, dynamic models are effected from light map. For example in dark areas, gun that player holds seems darker. How did they achieve this effect ? I can use image based lighting techniques however (Like placing an environment probe and using it for reflections and ambient lighting), this tech wasn't used in games back then, so there must be a simpler method to do this.
      Here is a link that shows how modern engines does it. Indirect Lighting Cache It would be nice if you know a paper that explains this technique. Can I apply this to quake 3' s light map generator and bsp format ?
