The GameDev.net FreeBook is relevant to game designers, developers, and those interested in learning more about the challenges in game development.

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.

Dynamically Load Entire Folder Of Textures At One Time

4 posts in this topic

I have recently started playing around with XNA and have run into a problem.
In all the tutorials / help guides I have read, they tell you to "hard code" every texture / image your going to use.

My project has hundreds of textures, which change all the time - Is there a way to load an entire file at once, and can you provide a working example of how to do this in XNA 4.0 ?

Thanks.

The ContentManager in XNA is the [i]main [/i]route from disk contents to game memory for every asset you want to use. There are a couple options:

1) Write your own importer for the ContentManager that takes a folder name and processes all the internal contents
2) Don't mess with the ContentManager classes, but write utility classes/methods that do dynamic loading/unloading of content and simplify the work for you a bit (these will still have to call ContentManager functions at some level)

The XNA Framework provides high-level but simple and straightforward utilities. Tutorials are only going to target the basic cases for these utilities to show how they're used. It's the difference between "how to swing a hammer" and "how to use a hammer to build a victorian-era gazebo". It's up to the programmer to use those basic tools to build something more complex and fitting to their particular requirements. You could potentially google around for open source XNA projects and see how they set up any kind of abstract asset manager pipeline. I would expect asset I/O to be coupled with game state management (for example, on level switching).

When you say "hundreds of textures which change all the time" are you referring to changing the individual textures' contents, or swapping out textures currently in use?

Edit: Spoke from experience, looks like there are some utility methods that let you deal with filestreams directly, see later post. Edited by BCullis

I am referring to a 2D level editor, that accepts custom .png textures from the user.
As it is written right now, each user has 6 private resource files ( unlimited textures in each one), and can have unlimited shared resource files ( downloaded from server ).

ContentManager and pipeline searches in Google isn't turning up anything useful as far as dynamic loading / unloading

Found a [url="http://forums.create.msdn.com/forums/p/84371/508411.aspx"]link[/url] to someone suggesting Texture2D.FromStream, that would let you avoid the need for knowing the asset's "friendly name" at compile time

Note: This won't work on the XBox. Edited by BCullis

Note that when using Texture2D.FromStream, you will have to handle compression, mipmaps and/or premultiplied alpha yourself, see here: [url="http://forums.create.msdn.com/forums/p/61813/380463.aspx"]http://forums.create.msdn.com/forums/p/61813/380463.aspx[/url]
