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

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.

Count occurrences in selected text

4 posts in this topic

Does anyone know of any applications that can count an occurance of a letter or word or whatever in highlighted text? Im trying to count the number of times a ',' is occurring in a file, but in only the text i have highlighted. Ive tried it in a few apps, Notepad++, in its Find Dialog, has the option to count, and a checkbox to select for "selected text" only, but for me, still seems to count occurances in the whole file. Context, has no count option UltraEdit, will only count on whole files, when selecting the "selection only", then greys out the count option. Also, another function ive been trying to find, is an editor that allows you to view selected data in any format. So say i have a hex editor app open, and i have a number of selected hex characters highlighted, i can view the selcted data as floats or ints or int64 etc etc Im on Windows BTW

On Textpad, if I wanted to count occurrences, I suppose I could do a "find and replace" within selected text, while using the same string in both the find and replace boxes. That would give me a note of the number of occurrences, and shouldn't affect anything.


If needed, I could simply undo the replace as well ... that might be needed, if the search was some type of regex, where the "find" string and the "replace" string might not be able to have the same value.



This trick might work on other editors, too.

In Vim, I select the text, do :%s/,//g (well, actually the command is :'<,'>%s/,//g but Vim fills in the '<,'> part), note the report of how many substitutions were made, and then undo (or quit without saving, as appropriate).
