      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.

Very well done! I really like how smooth and easy this is to use and how you can write custom code straight from visual studio. Good job on finishing this up and releasing it! :D

Edit: Is there any documentation on this yet?

Well, that's actually just a demo release - although it slowly goes near "actually usable", Duality is still in development! :)

That said, there is no documentation yet. The Asteroids demo makes a simple usage example but that's about it. Right now I want to focus on developing engine and editor, but whoever wants to give it a go and set up a small project in Duality on his own - I'll support you where I can! If you have questions, simply ask, if you need a specific example on how to do X or Y, it might help to have a look a [url="https://code.google.com/p/duality/source/browse/"]Duality's source code[/url]. Especially for writing your own Renderers, this will surely prove helpful.

I'm currently not sure what task to approach next, but I've been thinking about built-in 2D physics support (or at least collision detection), probably by using some open source library. Another possibility would be an ingame GUI system. Or I could simply develop some default Components for typical 2D game stuff like Tilemaps. The engine's and editor's basics are mostly done so far, but however, the most important task is to assure stability and usability of both. Since I'm my only tester, there might be a lot of ground uncovered - the usual problem when testing your own project. [img]http://public.gamedev.net/public/style_emoticons/default/rolleyes.gif[/img]

Wow, the camera and object manipulations look and work great. If that is OpenGl than good work! Will it have Linux support?

This is already a huge project for only one person and platform independence isn't something small to do, especially concerning testing, documentation and support. While running Duality on Linux and / or Mac is an achievable goal in theory, I'm not going to approach it. There is so much else still to do and I want to focus on actual functionality, documentation and testing right now.[img]http://public.gamedev.net/public/style_emoticons/default/smile.gif[/img]

Oh and yes, that's OpenGL, powered by [url="http://www.opentk.com/"]OpenTK[/url] which provides DotNet bindings and some pretty neat utility code.

The documentation might not be the best one ever written but it is a first iteration. You can try the new help system yourself in the [url="http://code.google.com/p/duality/downloads/detail?name=Asteroids.zip"]current Release[/url] and view the [url="http://ddoc.fetzenet.de/"]API reference[/url] online, if you wish. As always, thoughts and opinions are welcome :)[/size][/font]

Impressive work! Has a very clean and professional feel to it.
Do you want to release Duality as freeware/open source or do you hope to make some money with it?

[url="https://code.google.com/p/duality/"]Duality is OpenSource[/url]! Although I might choose to change the license later on, I have no plans of making it a commercial project.

The most obvious reason is that there are already a lot of commercial engines around, most of them beating Duality in terms of official support and feature range. Being a hobbyist on my own and not leading a whole professional team, I can't compete with their momentum and manpower in any way. Besides that, developing Duality is fun, I'm gaining a lot of experience and maybe someday seeing some people use what I've created is - in its own way - a great payment by itsself.

It's been a while now and there are quite some new features yet to be shown. Time for more videoblogging!

[url="http://www.youtube.com/watch?v=QzdCjVX7lVY"]http://www.youtube.com/watch?v=QzdCjVX7lVY[/url]

Basically, there's now a sandbox mode that lets you edit stuff directly in the editor. And Xml serialization. And a physics engine. Anyway, here's the download link to the new Asteroids demo (Now with physics [img]http://public.gamedev.net//public/style_emoticons/default/biggrin.png[/img] ): [url="http://code.google.com/p/duality/downloads/detail?name=Asteroids.zip"]http://code.google.c...e=Asteroids.zip[/url]

Any feedback appreciated! If anyone is brave or stupid enough to try to actually [i]use[/i] Duality for something - feel free to ask any question that occurs to you [img]http://public.gamedev.net//public/style_emoticons/default/wink.png[/img]

As I’m experimenting with the “custom Rendering” capabilities of Duality there happens to be a new tech demo for you to download and play around with. It features per-pixel lighting using directional, ambient, spot and point lights.

[img]http://www.fetzenet.de/blog/wp-content/uploads/LightingTest.jpg[/img]

Note that I didn’t touch any Duality code to implement the dynamic lighting technique – it’s all done inside the plugin.

For anyone interested in custom C# / Visual Studio debugging enhancements, you might want to take a look at my [url="http://www.fetzenet.de/blog/?p=616"]recent blog post[/url]. As side-effect of my work on Duality, I did some experimentation on what's possible there.

I'm pretty occupied by studying right now and there's a lot of work stacking up on my ToDo list. [b]But![/b] I spared a thought for [b]you[/b], fellow reader. In case you want to do some stacking yourself you can try my recent [url="http://code.google.com/p/duality/downloads/detail?name=Tetris_2012_04_29.zip"]Tetris demo[/url] of Duality. You see, I think everyone should get to stack some stuff. Also it's got a twist.

Fourteen. That’s the number of different joint types in the [url="http://farseerphysics.codeplex.com/"]Farseer[/url] physics engine. When I started porting it from XNA to OpenTk and glueing it into Duality they were pretty much left out entirely. Who needs joints anyway? Well. As I quickly found out myself, any kind of game that uses physics beyond collision detection is likely to need some kind of joint somewhere. Constructing doors, cars, buttons, hanging bridges, ragdolls, gears, ropes, moving platforms or even physical [url="http://amazingretardo.simiansoftwerks.com/2010/02/17/platformer-character-control-farseer-physics-engine/"]player characters[/url] – all more or less impossible if certain joint types are missing. So I spent some more time on physics that I planned to and integrated them all into Duality. And created a little physics demo for you to play around with.

For anyone interested in Duality, there is now a [url="http://www.fetzenet.de/blog/?page_id=697"]brand new info page[/url], summarizing the most relevant stuff. What is Duality? Why does it exist? How is it structured? And what's the benefit of using it? For anyone who thinks about working with Duality - or just wants to know what this is about: This is a good starting point.
