Andronaut and Curiosity 0.9, Academy, and Open Source
If you have access to Andronaut and Curiosity, you may have noticed a new update in recent weeks: version 0.9. This version will be the final release candidate before version 1.

Declarative Game Programming -- slides, videos and code
Earlier this month, Henrik Nilsson & Ivan Perez presented a tutorial at PPDP 14 on Declarative Game Programming.
The goal was to show how real game programming is possible in a purely functional, declarative way. One way of doing so, seeing games as networks of interconnected signals and signal transformers, results in clear, reusable, modular code.
To illustrate these ideas, a small but realistic game was demonstrated, featuring many of the complex elements found in arcade games: SDL graphics and sound, Wiimote controller, and differentiated subsystems for rendering and sound, game input, physics/collisions, game logic, etc. The game has several levels, each with its own background and music.
To help others interested in functional game programming, all the talk material have been made available, including the slides and the full game code.

A new version of Yampa is out (0.9.6)
Yampa is an impressive, arrowized, Functional Reactive Programming (FRP) implementation written in Haskell. We are using it to implement Android games at Keera Studios, and it has been used, among others, to implement the video game Frag (see video below).

The most inspiring green screen you will ever see
While Haskell, Idris and other Functional Programming (FP) languages enable writing elegant code, the road to production is, well, bumpy. Writing code for industrial environments has added costs that make certain products too expensive and infeasible in practice.

Interacting with your Haskell Games using the Wiimote
Quite recently we have been focusing our attention on using new input devices in Haskell games. Wiimotes have many sensors, they are very cheap, and people have been hacking them for a long time.

Delving into Reactive Values
In a previous posts we examined the current state of GUI programming in Haskell, how imperative libraries get in the way of functional beauty, and how (non-FRP) reactive programming enables short, declarative code and facilitates code reuse. But without the low-level details, without more information on how this framework is structured, all we have is an idea, a draft on a piece of paper. It’s impossible to know how much effort it will require, or how much it will affect our code.

Keera Hails: functional event-driven programming of desktop applications in Haskell
Some time ago I tried to create big programs with user interfaces in Haskell and found that none of the FRP frameworks worked as expected. Some were incomplete, others didn’t compile, and efficiency was an issue in those that did work.
