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++ 2D Isometric map problem

6 posts in this topic

Hii guys (: 

i'm having a little trouble "converting" my tilemap to an isometric tile map. 

Or i'm not really converting, actualy writing the code all over, but i cannot make the freaking "isometric map" work. 

Is there anybody in here, knowing a good homeside, tutorial anything really about it. Cos i have been looking all over the internet for a fix. but i can only find java samples and such, and everytime i try converting them into c++, i fail :D 

So i reeeeeallly need help guys :D 
Thanks for your time, sincerly Wunderstrudel.

So you have any specific questions?

 

Ohh yeah, i could have been more specific i guess, sry about that d: 
My problem is getting to "draw" / making the tile grid. in the isometric / diamond shaped way. 

And ofcos getting my "64x32" sprites fittet over the grid (: 
I cant really remember the function in my head, but what i'v seen so far was something like: 

For(int index = 0; index < Max_rows; index++)
{
    for(int indey = 0; indey < Max_Cols; indey++)
    {
     Drawx = (This Algorithm is where my problem lies)
     Drawy = (This Algorithm is where my problem lies)
    }
}

and i'm not even sure that that is even remotely correct d:

This gamedev tuts+ article is a really nice introduction to isometric perspective in video games: http://gamedev.tutsplus.com/tutorials/implementation/creating-isometric-worlds-a-primer-for-game-developers/ Not C++ specifically, but the underlying theory remains pretty much constant for whatever language you choose to work in.

If it's specifically the coordinate conversion formulas you're having trouble with, check this article out: http://clintbellanger.net/articles/isometric_math/ It was written by Clint Bellanger, the lead developer of the FLARE (Free/Libre Role-Playing Engine) project, and it's unquestionably one of the best resources I've ever found on the subject. It helped me immensely when I was trying to figure out isometric math. :)
