OK, folks, here is a small package that demonstrates all of the play-sound issues I'm having, in one go:
http://drewhess.com/drew-bootstrap.zip Install both of the teachpacks. The -no-runtime-path version of the teachpack is nearly identical to the version I used with PLT Scheme 4.2.5, and in fact will probably compile in PLT if you replace the racket/* requires with plt/* or whatever the namespace was in the PLT days. The other version is the one I whipped up to fix the relative pathname issues. (Please don't judge the quality of the code in those changes! I wrote them hastily at the end of a very frustrating debugging session :) Load the drew-game.ss game. It uses the "fixed" version of the teachpack. It should work fine, except for the fact that, on Mac OS X, the game will pause when a sound is played. This demonstrates the inverted-ness of the play-sound async flag on that platform. (The Windows version will not pause when the sound is played; however, while we're on the subject, it is annoying that play-sound on Windows cannot dynmically mix sounds like the Mac version does; it just stops playing any sound that it was already playing and starts playing the new one.) Load the drew-game-no-runtime-path.rkt game in Racket 5.1. This version uses the -no-runtime-path version of the teachpack, i.e., the version of the teachpack that worked fine in DrScheme 4.2.5. You will see that, when a sound should be played, e.g., when there is a collision, the game freezes, and, on the Mac, at least, no error message is displayed in the Interactive window. (It should be trivial to port the -no-runtime-path teachpack to DrScheme 4.2.5 and run this version of the game in that environment to demonstrate that it works fine there.) thanks d _________________________________________________ For list-related administrative tasks: http://lists.racket-lang.org/listinfo/users
