      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.

Getting Function Body From Script File

2 posts in this topic

Hello everyone! I have another fairly trivial question to ask.

As per suggestion last time, I decided to go with an existing scripting language instead of rolling my own. I've realized by now that that was ultimately a better decision.

Now, I am trying to build into my game editor a scripting section which will allow the user to modify the functions inside a script (some functions are generated by the GUI builder and other behavior can be programmed by the user). Creating the editor inside the builder and writing the code to save the text from the editor in the proper place in the file was a triviality. Now, I need to be able to read the code back and separate it by function.

My question is, is there some way I could use the jython interpreter, which I got from [url="http://www.jython.org/"]http://www.jython.org/[/url], to handle this? I'm trying not to write a special parser just so I can separate the code properly. I know I can read in a class into an object (the level script contains a single class that describes the level) and operate on the separate functions, but is there any way to get the function code from that object in String format?

How about splitting them into multiple files? Put related functions (GUI generated etc) in a file, and show that to the user for editing. Is it really important to show each function separately? And if so, is it really important to store all functions in the same physical file?

Cheers

That gave me an idea which I should consider.

I've made the script loader in such a way that I'm not really able to readily split the file into separate ones for each function. I've created an interface that defines the functions for a level script class object and the scripts implement said interface in their classes. Then my host code can parse the files, instantiate the script object that implements said interface, and it's functions can be used like that of a normal object. I'm not really sure how to replicate the "function pointer" functionality that I'd need if the functions were in separate files. XD What I meant probably makes no sense. It's basically: write level class implementing interface, and then in Java, instantiate the object and call it's function by the interface.
