      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.

  1.   Reflect it in the plane which is normal to the cone axis first then proceed as before. If you are already on that plane add some scaled amount of the cone direction to it.
  2. And if you need to clamp it you can just subtract a vector in direction from the end of the the orientation to the end of the cone axis until the cosine is equal, then renormalise, I believe.
  3. Use an axis and an angle, then check whether the proposed orientation dot axis is within the angle, it's a cone check, if both axes are normalised the dot product will be > cos(angle) if it is within the cone   EDIT: > not <
  4.   And incorrect ;) 0 is not a negative number
  5. You would use porsche.Steer(); in the member function PorscheSteer. But Steer is public anyway, so there's no need for it to be a friend to call that function...
  6. You should remove degenerate triangles from your triangle collision data when you export the data. If you need collision against lines have a separate container for them and do line vs. collision object tests as different functions.
  7. Either only initialise w in the t4dpoint class (base class is then default constructed) or call the base class constructor directly   t4dpoint<_cType>(_cType a, _cType b, _cType c, _cType d) : t3dpoint<_cType>(a, b, c), w(d) {}   should work...   EDIT: Which is what Brother Bob said as well. I'm not sure if my template argument is needed for base class constructor, I have it, Brother Bob does not. One or both of us is correct ;)
  8.   I gave up on Shenmue 2 when I had to do a cut scene every time I walked across a plank to climb a building many times in a row... And I never did get to find out where sailors hang out at night.
  9. It should be width * currentHealth / maxHealth anyway? So if your max is 100 and current is 25 it will be 25/100 = 25% full...
  10. Can you do a left shift by using a negative value as right shift amount?
  11. Upvoting increases your rating by 1 as well, there's a limit of 5 a day of that though?   Maybe you shouldn't get a rating boost for upvoting someone's post at all? (And a rating hit for downvoting?).   EDIT: Well maybe you should still get a rating hit for downvoting to discourage downvote sprees. But as mentioned before people then uprate to cancel that out anyway.   And while the number in itself might not have much value, being one of the top-rated posters might be.
  12. Yes you can use sprites and render them in screen space look for a point sprite or point particle demo to see how to do that.
  13. Heroes of might and magic: clash of heroes was like that. There were different levels against slightly different armies/generals but it was basically same thing over and over. I liked it got it for free with games with gold on Xbox 360 played it to the end.
  14. In 2d, shoot a ray out in any direction. If it crosses the lines of the shape an even number of times (0 is even here), you are outside. If it crosses odd number of times you are inside.
  15. The interval of convergence is too small.   Are you using floating point or fixed point, I don't understand what you mean by this: of floating range from 24 bit to like 16 bit.   Using 1/x is going to be a lot more accurate than a (poor) approximation which is what the Taylor Series expansion about 1 will give you. Some functions aren't approximated very well at all by Taylor Series (of which McLaurin series is just a special case), e.g. sqrt(x).   Or you could use the Laurent Series, f(x) = x-1
