Like many of you, I have been reading about functional programming and F# for a while just trying out a few bits of code here and there, then I realized that adopting a functional paradigm was not an all or nothing option. In this talk we'll go over some interesting ways to adopt F# within a game project. We'll go over a short F# intro, C# - F# interaction, property testing and other fun stuff. Using F# and Duality(an open source engine) Intended audience & prerequisites: Programmers of Object oriented languages interested in a progressive move to a functional language, particularly suitable if they use C# Session takeaways: Basics of practical functional programming for games projects.
