4Blocks Source Code

7 05 2010

Today I decided to try my hand at releasing a cabal package with the 4Blocks code. I finally managed: http://hackage.haskell.org/package/4Blocks-0.2. (I made a newbie mistake in 0.1 so please ignore that release).

Unfortunately the library can be compiled only with, as far as i know:

  • GHC 6.8.3
  • Gtk2hs 0.9.13

The reasons why are in the README file in the cabal package, copy/pasted here:

Some notes:
– The game currently works only with GHC 6.8.3 due to its use of Gtk2hs 0.9.13.
– I haven’t tested with anything later but it is likely to fail due the fact that later versions of Gtk2hs have a different system of handling events.
– To make this project compatible with later versions of GHC and Gtk2hs two changes are required:
– Remove the function “permutations” which was copied from a later GHC base library
– Alter key-event handling to the version used by later Gtk2hs: some functions (in CommandKeys.hs) were simply introduced in order to disallow some of the keys used in the game (namely rotation) to trigger continuously when a key is held pressed. I believe this kind of behaviour can be managed automatically with Gtk2hs’ new event handling mechanism, however I haven’t had time to recode accordingly myself.
– I hope to write a patch for this in the near future.

So yeah, fairly old now, but I thought, I’d share the code all the same as some people have requested it earlier. Hopefully I will release the code with my AI later on after my project is over and done with in summer and also a patch to make it work with newer versions of GHC and Gtk2hs.

I have to say I really enjoyed coding the game in Haskell and if you have any comments for me, regarding better ways to code stuff, silly things I did, or anything else please let me know by leaving a comment!
