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.

Animation workflow

The last couple of days I took a brief hiatus from coding. Spent the time doing a new re-topo of the GC model, and building a new IK-enabled rig to do animation more easily. Visibly, he doesn't look much different, but gone are some of the weird deformations when he animates, and gone as well is the weird line that sometimes appeared on the back of his skull at certain view distances dude to the crappy UV mapping.


I actually ran into a few issues in the process. Recent versions of Urho3D ship with a Blender exporter to export directly to the files Urho3D expects, and it works very well for most things. But one thing it didn't seem to like, at all, was having my IK controls and posing bones inside the same armature as the deform bones that skin the mesh. For whatever reason, it just wouldn't export a functional animation with the new IK rig.

I ended up sorting it out, after some hours of despair and panic as I tried any number of combinations, formats, etc... I found that if I separated the IK control bones and targets to another armature (maintaining the constraint cross-links between the two armatures) then it exported just fine. It does add the slightest bit of work to the animation process, since I now have to keyframe two different armatures during the process, but that slight overhead is more than compensated for by the ability to IK my rig and make ostensibly better animations. I say ostensibly, because no number of clever IK rigs can really make me what you might call a "good" animator. I'm shite, it's true. I ham-fist GC into all manner of tortured poses, look upon my work and call it good. But it's not good. His idle animations sometimes look like he is reeling from too much goblin brandy, and he walks like a popsicle; that is, like he has a stick up his nethers. But still, with the new rig, it all does look a lot better.

The new retopo still isn't perfect; I'd imagine a real artist would be appalled. But it's far better than the old mesh decimate retopo.

That being done, I can bang out a couple more animations pretty quickly, so that he isn't stuck in the eternal walk cycle that he has been. Needed to do this to test out the action->animation mapping anyway.

Started redoing the character portrait widgets. Just a first iteration for now, need to rework the life bars and what not for use with the new UI system. That'll be a job for tomorrow, after I've done an Attack and Use/Loot animation.

Looks good keep up the good work. The only thing that is bothering me is the shadows, the light source from the fire doesn't reflect the shadows at all. For example on the bush, the shadows are forward, even though the fire is in the foreground.

Heh, whoops. I had shadows turned off for the campfires.


I always have one light hovering above and behind the player, hence the one strong shadow. Other lights don't have the brightness or range of the main player lamps, so their shadows tend to be a tad fainter.
