Declarative Processing for Computer Games

Databases are often thought of as nothing more than solutions for persistence. However, the area of database research has developed a wide set of ideas and techniques with applicability much beyond persistence.

In this talk, I will show how the idea of declarative processing from databases can be applied to computer games. I will describe our journey from declarative to imperative scripting languages for computer games, and I will introduce the state-effect pattern, a design pattern that enables game developers to design games that can be programmed imperatively, but processed declaratively.

Scalable Games Language (SGL), our scripting language for games, supports this design pattern, and I will describe how database techniques can be used to process SGL resulting in performance improvements by an order of magnitude or more compared to standard scripting languages. I will finish with a discussion of ongoing work, future challenges for SGL, and applications of SGL to cloud computing.
