IO bugs in the Asteroids demo program about reactive-banana HOT 8 CLOSED

The issue with keyboard events is really weird, because the left and right arrow keys work for me.
(One issue I do know is that on Mac OS X, you have to run the application from the .app bundle, not from the command line. Not sure if that is relevant here.)

Concerning the "Game -> New bug", I can reproduce this and it's indeed a bug internal to Reactive.Banana.PushIO. Thanks for catching this! Confusingly, it only happens when you compile the package via cabal, not when you compile all modules by hand. Looks like I messed up with unsafePerformIO and inlining.

Figured out how the "Game -> New" bug works: it's due to a secret dependence of the compile function on some global mutable state. Fortunately, I intended to exorcise this anyway, so I'll do that sooner rather than later now. (I sure hope that the Purely Functional Inquisition won't hear of my use of mutable state, or I'll be in for some exorcising myself...)

(1) Hmm. Now when I create a new game, I get a whole second window, but the original window still runs! :D

(2) It looks like I could already print key events, and now I'm wondering if event1 f keyboard is ever triggered at all, here...

(1) Now, this is a feature, not a bug. ;-) The example is basically a direct port from the wxAsteroids example, which has the same behavior.

(2) I'm stumped. Does the original wxAsteroids example have the same problem?
If not, what happens if you delete lines 80 and 81, i.e. the two additional on (charKey ..) events?

from reactive-banana.

(1) Aha.
(2) Yes, it has the same problem! Hmmm.

(2) In that case, I can't do much. :-( Maybe your OS / windowing system doesn't support key events on frames and you have to wrap the game area into a panel? You can also try to ask on the wxHaskell mailing lists, but they're not very active.

I have updated the wxAsteroids example to use a panel (commit 5a94ae3). Does it work now?

from reactive-banana.

The left and right arrows and the CTRL-N combo work as expected now. :)
