      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.

  2. You can't really draw a circle like that in code, round things are faked, you need to use trigonometry to plot each point.   Loop from 0 to 2?, for a rough circle, plotting points at:   x = cos(?) * r + pos.x; y = sin(?) * r + pos.y;   pos is your offset or 0, as your radius increases it won't move since sin and cos go from -1 to 1.
  3. 5 months finally did over 1,000kms in my car... Anyone want to buy it? :)
  4. Cleanup ancient spreadsheet by removing borders found in the middle of nowhere, standardise border widths, change neon colours to pastels, align text correctly, add conditional formatting, use the same formulas. No no no this is wrong, where is the old data, change it back.
  5. This sounds quite fun. I think removing fog of war is okay, check out the Starcraft maps Zone Control, and also Starcraft Evolves UMS. I imagine it playing out something like this, with a giant brawl, and position being everything (except coordination will be more difficult because you have individual players for each units, rather than controlling a single army)
  6. Agreed Inkscape can do 16.7million colours too, just like Flash, or Illustrator. While SVG's do have some use, making cartoony graphics with clean lines, or rescalable UI and buttons, this software doesn't appear to solve any problems? Not only is converting a photo to a vector relatively useless - why do you want to scale a photo up that much, you could just load more, most cameras take photos at a very high resolution - vectors are also very low performance compared to standard bitmap data. I don't see any GPU's out there that let you push SVG points. Unless your photo is very repetitive, you are going to end up with an SVG rectangle for every pixel, making very little space gain (if not negative, SVG is stored in XML), and also reducing rendering performance. Flash less interactive than your app? You could develop the Flash IDE in Flash theoretically.
  7. Simon, you seem to be concentrating on multiplayer games only: Even World of Warcraft has problems with people finding ways to modify the client. People cheating in PvP by removing walls \ doors from their local maps, making other characters heads much larger so they can be seen from a distance etcetera. Yes this could be solved if they went ahead and did server-side collision checking, but apparently it's not worth the work and extra processing power required for that very large company. Imagine how much easier it would be to modify if they gave the whole client source to everyone? People already reverse-engineer 'private' servers for many of these pay-to-play games, but it does take months to years before they get released. I see two issues. - Modification and re-hosting (especially if they reverse engineer the server too), removing the need for users to spend money on the original game at all. - Easier hacking & modification, now nothing can be calculated client-side. Your 'perfect solution' is at the level of rendering server-side and pushing through video, and just letting the client send input. (Not a solution that is going to work for Australian players) You can say it is irrelevant and that the game has been designed incorrectly if something is dependent on client-side calculation, but I think it's just a reality in many games.
  8. I think a large part of the problem is that Javascript is the only language you can use to hit all the browsers supporting HTML5, and it is plain-text and cannot be pre-compiled. Although tools exist to minify and obfuscate your Javascript there are many tools to do the reverse. I don't think transactions are the big problem, they can occur securely, but actually restricting the benefit. Imagine you download all the HTML, Images, Sounds, Javascript with your browser, re-host them, and removed the Javascript saying if (purchased == true)... Well, now users have no reason to complete a purchase. Of course with an MMO you can validate server-side so other clients won't see you in all your epic gear, and you can't spend your fake gold where you edited variable x, but you get the point.

  11. Puzzle Attack is a match-3 game developed by myself, based on some other popular Facebook games. In this journal I want to talk about the benefits of integrating social networks such as Facebook into your game, and how you can measure these benefits with services such as Google Analytics. First let me say, it's incredibly hard to develop a Facebook integrated game while travelling in China! I can't test the game in production or any of the sharing features whatsoever, I submit all errors as 'events' to the Google Analytics api to track any errors, none so far other than a few connection errors when I ran the game locally. I made a few changes the other day so you can see a number of connection errors. (0 = Connection Failed, 2 = Web Service Error, 7 = Database Error) You can also track data such as the major landing pages, (always the same since this is a game rather than a web page we are tracking) and the exit pages. It is concerning me that more people exit mid-game than from the main menu, and there is a 15% bounce rate in the initial connecting page. I track events such as inviting friends, and sharing highscores \ achievements via page views. The sharing clearly correlates with new users joining. It's really interesting watching the daily progress, the game has not been marketed or shared anywhere (previous to this post), but somehow I got a hit from a player in the Philippines, and it has spread to a number of players there, and branched over to Malaysia and the USA. I'll be sure to share future progress when \ if there is a larger data-set.
  12. [img]http://puzzleattack.com/resources/920x368.png[/img] [url="http://www.puzzleattack.com"]Puzzle Attack - Play Here[/url] Decided I'd have a go re-creating some popular Facebook games in Flash, Puzzle Attack is heavily integrated with Google Analytics which was very easy to do. Analytics works great, the game was played by one person in the Phillipines who shared their score, and I've watched it spread over that country, over into Malaysia, then another branch started in France, going over Europe now.
