The sound() command is not yet finished, but it mostly works. HOW TO STOP THE SOUND IF IT REFUSES TO STOP: CodeSimian now has a "CodeSimian_Controls" window that starts when CodeSimian starts. It has 2 buttons for turning off sound: 1 that executes the code: sound(0) and 1 that executes: do(sound#s(0) deleteP(s 0)) You usually need both to fix sound-related problems. THIS IS THE CODE FOR THAT CodeSimian_Controls WINDOW... You might need it if you close the one that opens with CodeSimian... window#CodeSimian_Controls( horizontal( horizontal( button#Exit_CodeSimian(method#java.lang.System.exit(0 0 0)) button#stop_all_sound(sound(0)) ) button#stop_sound_from_slowing_down_computer(do(sound#s(0) deleteP(s 0)) ) ) 550 70 )
