      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.

[C#] Image Manipulation

6 posts in this topic

I've been toying around with the idea of a 2D game for a Windows game based on the XNA framework. Sprites, I can handle. But what I'm looking for is a way to animate an object (namely a person) that has multiple layers (foot, leggs, arms, etc.) and I would like to animate each individual part. I've poked around for 30 minutes now unable to find anything as to [b]how[/b] to do this (i.e. change rotation, position, anchored to, etc) and I was wondering if anyone had a good idea how to do this and/or where I can find a tut on this.

Try and be simple for my sake, I'm not very familiar with XNA framework and C# is relatively new to me.

Thanks in advance!

Hi Morley, one of the problems with this type of query is that you might be hoping for a far more simple answer than most people will give you. The subject your looking into is actually quite a vast one, and you'll be hard pressed to find a library that will just offer this type of functionallity without some compensation. Saying that though, a few months back I was looking into the same subject (only in 3D instead), and came across this article based on OpenGL:

[url="http://content.gpwiki.org/index.php/OpenGL:Tutorials:Basic_Bones_System"]http://content.gpwiki.org/index.php/OpenGL:Tutorials:Basic_Bones_System[/url]

Now I know it's not XNA, but the tutorial is a good starting point, and it covers 2D quite well, so I think it might aid you on your way. Anyway hope this helps somewhat.

Aimee.

This seems to be what you want: [url="http://www.catalinzima.com/2011/06/2d-skeletal-animations/"]http://www.catalinzima.com/2011/06/2d-skeletal-animations/[/url]

@AmzBee quick question, how do i store the following line of code from the tutorial you showed me:
[code]
#define BONE_ABSOLUTE_ANGLE 0x01
[/code]


[s]I think Char, but I'm not sure.[/s] I hating translating between C++ and C# :P

*Edit* I officialy don't know which type to use so that I may easily edit it and read it trhough the program.

*Edit 2* float i think would work. Confirm?

(I am new to this, sorry)

@Nypyren, looking at yours shortly. Thanks :)

C# can use #define [url="http://msdn.microsoft.com/en-us/library/yt3yck0x.aspx"]http://msdn.microsof...y/yt3yck0x.aspx[/url]

EDIT:
Oops! It would help if I read the article I linked to. Sorry!

Oh...a hex value can be stored in an int, unsigned int, long, unsigned long.

As for using it as a global constant, it seems the accepted method (in c#) is to create a static class with your constants in it and declare them [b] public const[/b]. [url="http://www.dotnetperls.com/global-variable"]An article for reference.[/url]
