[Haskell-cafe] ANN: Dungeons of Wor - a largish FRP example and a fun game, all in one!
Hello all, I just uploaded the first public version of Dungeons of Wor [1], a homage to the renowned three-decade-old arcade game, Wizard of Wor. While it makes a fine time killer if you have a few minutes to spare, it might be of special interest to the lost souls who are trying to figure out FRP. The game was programmed using the Simple version of the experimental branch of Elerea [2], which provides first-class discrete streams to describe time-varying quantities, and the main game logic is described as a composition of streams instead of a world state transformer. Developing in this manner was an interesting experience, and I'll write about it in more detail over the weekend.

I don't have a Mac, but I heard that GLFW is not without problems there, so maybe it's the culprit this time too. Do other GLFW apps work on your machine?

Just a thought: maybe it is something else. That function appears to exist since Windows 95 according msdn[1] and OpenGL 1.1[2].

Seems like today FRP is the last word in game programming with Haskell. Do you know something that could be a good tutorial, or at least introduction to FRP ? Something that could somewhat help me learn the ropes, 'cause I'm afraid if I dive directly into your code I'm gonna be lost. Good job, by the way.

I got some other error reports too (about segfaults under Linux), but I can't reproduce any of them.

I don't think there's any material on FRP that could be considered a general tutorial, because there are many flavours with smaller and bigger differences, and no-one really seems to know how to program in this manner beyond toy examples. So, for the time being, I'd probably start with the original Fran paper [1], which is quite accessible in my opinion, and even though some of the details are obsolete, it explains the basics reasonably well. The Yampa Arcade [2] is probably the best introduction to the arrow-based approach (AFRP). The new Reactive paper [3] is not beginner friendly, but if you already grokked Fran, it shouldn't be too hard to follow, and it describes a way to design an applicative style reactive library with a much cleaner interface than that of Fran.
