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.

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.

Isometric Tiling Algorithm

1 post in this topic

I am designing a game that will require me to use isometric, tile based style graphics.

 

I have read posts that just say to draw all of the graphics out and then just rotate the map 45 degrees. Is this the correct way of doing it, or are there some more sophisticated algorithms out there for dealing with this style of graphics. I want enough control so that I can implement collision detection and path finding (already done both of these things in some simple 2D tile based games) I will be using the Java Programming language, so I would prefer any sample code (if any) to be either sudo or in java.

 

There don't seem to be any good tutorials out there covering how to do it in anything other than action-script, and even then the guy just uses a library to handle most of it for him, he doesn't explain any of the techniques that are used. So if anyone knows of a good tutorial (video or text) please post a link.

 

One more question referencing the actual creation of the graphics. When I am drawing the tiles in Photoshop, do I draw them already rotated on a rectangular canvas, or do i draw them, un-rotated and then rotate them in the engine ?
