• Various author-created game frameworks are presented and are used to illustrate the UnrealScript programming language and user input methods specific to the iOS mobile platform

What you’ll learn

• What the UnrealScript programming language is and does
• The basic Unreal UDK base code framework
• What the basic Unreal tools used to make a game
• What the key parts of the Unreal engine such as the physics engine
• How to do the fundamentals of 3D games programming, including basic 3D math
• What are the the basic frameworks of many different types of games
• How to use the provided source code to build your own games using the frameworks as a reference

Who this book is for

Game programmers, both professional and hobbyists,interested in developing 3D games for the iOS platform using the Unreal UDK.Additionally, students using the Unreal UDK in their coursework. Finally,game designers who are not experienced programmers but are interested in learning enough about UnrealScript and the Unreal UDK to make small changes to game code created by contracted programmers (For example: changing code to increase the health of a player or change the message displayed when a player dies).
