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.

PhysX examples of static,dynamic and kinematic actors

4 posts in this topic

Ok,reading the documentation of PhysX made me a little dizzy.So,can someone give me some examples of some statis,dynamic and kinematic actors?

Also: suppose I have a third person game,so I'm in control of a character.When I move my character with W,A,S,D,my character is a dynamic actor or dynamic kinematic actor?

also(some real definitions of static,dynamic and kinematic actors would help a lot!).Thanks!

Static doesn't move ([i]e.g. a building or terrain[/i]). Dynamic can move ([i]e.g. a cardboard box or a vehicle[/i]).

Kinematic is a dynamic actor that can ignore the rules of physics, and just does what you tell it to ([i]e.g. a player controlled avatar or a scripted elevator[/i]). This is kind of a hack that lets your game directly control the player without worrying about dynamic objects being able to knock them around, or having them fall over due to being off balance. You're responsible for their movement, and they can knock dynamic stuff out of the way. They're used when you've got your own simpler version of physics that you want to use for an object, and you don't want the physics engine to have any control over it. Edited by Hodgman

So if I make a third person shooter game,my character that I control with W,A,S,D, should be a dynamic actor or a dynamic kinematic actor?

[/quote]This is what kinematic actors were designed for, yes. However, you're then responsible for all of their movement logic, including gravity, etc...

N.B. a dynamic actor could also be used, but you face [i]different[/i] problems in that case, such as making sure they don't fall over sideways, etc... Edited by Hodgman

there is a major caveat for kinematic actors.
they do not trigger callbacks.
you will not get a callback when a "box" hit a kinematic object.
you need to use rays or sweeps to get objects around your actor.
