  • Software Reuse in Game Development: Creating Building Blocks for Prototyping
    DEGREE PROJECT IN COMPUTER SCIENCE AND ENGINEERING, SECOND CYCLE, 30 CREDITS STOCKHOLM, SWEDEN 2019 Software Reuse in Game Development: Creating Building Blocks for Prototyping RICKARD BJÖRKLUND KTH ROYAL INSTITUTE OF TECHNOLOGY SCHOOL OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE Software Reuse in Game Development: Creating Building Blocks for Prototyping RICKARD BJÖRKLUND Master in Computer Science Date: June 5, 2019 Supervisor: Cyrille Artho Examiner: Martin Monperrus School of Electrical Engineering and Computer Science Host company: EA DICE AB Swedish title: Återanvändning i spelutveckling: byggstenar för prototyping iii Abstract As games and the technologies used by them have become more advanced, the cost of producing games have increased. Today, the latest AAA titles are the results of hundreds or as many as thousands of people working full-time for years, and even developing a prototype requires a large investment. This project sets out to reduce that cost by looking at how reusable building blocks can be used in the prototyping process. During the project, seven interviews with game designers were conducted. The interviews found that building character controllers for the player was the most common activity and one of the more difficult tasks when prototyping a new game. As a result, a tool for creating character controllers was made. The tool builds the character controllers to work as state machines where actions in a state and transitions between states are editable through a visual programming language. The visual programming language uses nodes. These nodes work as reusable building blocks. The tool was evaluated by six game designers and four programmers who all thought the tool used a good approach for building and prototyping char- acter controllers.
