Beginner ’ s Guide to Unreal Development Kit

1. Beginner’s Guide to Unreal Development Kit Hanshin University Spring 2012

2. Unreal Engine • Unreal Engine • a game engine developed by Epic Games • first illustrated in the 1998 first-person shootergameUnreal • The latest release is the Unreal Engine 3(UE3), designed for • Microsoft's DirectX 9 (for Windows and Xbox 360) • DirectX 10 (for Windows Vista) • DirectX 11 (for Windows 7 and later) • OpenGL for Mac OS X, • PlayStation 3, Wii U, iOS, Android • Stage 3D for Adobe Flash Player 11.

3. Unreal Engine • Versions • Unreal Engine 1 (1998) • First generation Unreal Engine integrated rendering, collision detection, AI, visibility, networking and file system management into one complete engine. • Unreal Engine 2 (2002) • Support for the GameCube and the Xbox. (PlayStation 2 in UE1) • UE2.5 : improved rendering performance and added vehicles physics • running on the Nintendo 3DS • Unreal Engine 3 (2004) • designed for DirectX, OpenGL, including iOS, Android, and Adobe Flash Player • November 2009, Epic released a free version of their engine, called the Unreal Development Kit (UDK) • Unreal Engine 4 • targets the next generation of PC HW & consoles after the seventh generation. • Unreal Engine 4 would be unveiled to limited attendees at the 2012 Game Developers Conference.

4. UE3 vs UDK vs UT3 • UE3 vs UDK vs UT3 • UE3 is Unreal Engine 3. • UDK(Unreal Development Kit) and UT3(Unreal Tournament 3) are both powered by Unreal Engine 3 • Unreal Engine 3 = UDK and UT3. • Unreal Editor interface between the UDK and Unreal Tournament 3 are essentially very similar.

5. UE3 vs UDK vs UT3 • UDK • Free stand alone version of Unreal Engine 3. www.udk.com • New engine updates, and improvements being released almost on monthly basis. • Purchase a license and sell your game with UDK. • Ideal to create stand alone games. • You can package your created maps and games as a stand-alone executable. • Free to create any game, only limited by know how. • Limited amount of models and textures • UDK was designed in mind for game designers and environment artists to take the base of UDK and create brand new custom content • UDK does not include Unreal Engine 3 C++ source code access

6. UE3 vs UDK vs UT3 • UT3 • Purchase the game and editor comes with it. • Lots of models, textures, particles, vehicles, weapons. • Large community. • You'll have access to all the source code files for weapons, vehicles and characters in Unreal Tournament 3. • Complete full game. • Ideal for level design. If you are not good with creating custom models and textures using 3d modeling package, Unreal Tournament 3 is good choice. • Has not been updated with new features like UDK and runs on the old build of Unreal Engine 3.

7. UDK Installation • UDK DOWNLOAD AND INSTALLATION • Download latest version of UDK here. • The default directory for installing UDK is C:\UDK\UDK-VersionRelease • Version Release will be the month and year of the UDK built that you downloaded. • UDK FOLDER STRUCTURE • Binaries: game/binary executables • Development: source code for UDK • Engine: engine files • UTGame: game files • for level design and environment creation the important folder here is content folder. (UTGame  Content) • The packaged environments assets such as models, textures, materials, sounds and such are stored here.

8. UDK Installation • File Extension • .UPK : UDK packages name. • This is how the models, textures are stored in UDK. • all the models, animations, textures, materials and similar assets are stored. • .UDK : map file extension. • LAUNCHING THE EDITOR
