      Download the Game Design and Indie Game Marketing Freebook   07/19/17

      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.

Unreal Engine 3: Code

10 posts in this topic

So I am learning C++ and I heard that you need C++ for most game developments. But when I went to go and watch a tutorial on the UDK I saw a 3D modeling program. I am aware of kismet but how do I implement C++ code to use the UDK. Or what language should I use I don't want to use actionscript because I cannot handle memory management like C++ can. Any links or other forums for the answer is helpful.

Thanks,
-Noob

The UDK uses Kismet and UnrealScript.
Only the professional version of Unreal Engine (not the free UDK) allows you to use C++, AFAIK.

If you're new, then you shouldn't use C++ anyway -- it's an advanced, low-level, systems programmer's language, not a beginners game programming language. Edited by Hodgman

Then in your opinion are there any limitations in unrealscript versus cpp?

Unrealscript can only be used with Unreal Engine / UDK and "only" lets you control the unreal engine.

C++ can be used for anything(almost) but supports almost nothing. it is great for building new systems but not really a nice language to use for controlling existing systems. (Which is why so many games these days use higher level scripting languages(unrealscript, lua, python, etc) for the game logic)

UnrealScript is meant for use with unreal engine only and is a highly abstracted scripting language that allows you to focus on writing gameplay without dealing with advanced programming concepts. Performance wise, its much slower than C++, as it uses a middle-ware interpreter to execute. However, for "almost" all gameplay programming needs in UDK, it should suffice. Infact, even Epic suggests to code gameplay with UnrealScript and not C++, unless you are working on really performance driven engine code.

Hope this helps.

UDK is not free? Hence why not use OGRE etc.? Maybe have a look at gamekit?

I know c++ and Blender, so I'll go with Ogre unless someone has good arguments against.

UDK is free and if you want to go commercial it is ~15 times cheaper than unity (99 USD for license with UDK opposed to 1500 for Unity Pro). UDK is VERY free and everything shipped with it is 100% AAA and tested time and time again to be the best out there. You don't win best engine of the year several times in a row for no reason.

Also it is very interesting to see so little knowledge of UDK on this site.. maybe I should do some posts about it (or maybe I'm just in the wrong forum)?

Most people don't know this but you can use C++ libraries with UDK by using the "DLLBind" feature:

In fact one clever guy figured out how to trick DLLBind into calling into C# libraries yet this is not officially supported.

Wait for UDK 4 for and we will only have kismet and C++ code they have gotten rid of UnrealScript [img]http://public.gamedev.net//public/style_emoticons/default/smile.png[/img], also dynamic C++ compiling on the fly. See last 2 minutes of video.

Yes looks good, but unless I could export to Linux, I won't even bother to look at that. Edited by mike4
