Message-ID: <6012@mva.cs.liv.ac.uk> Date: 5 Dec 88 11:53:39 GMT Lines: 19 Organisation: Computer Science CSMVAX, Liverpool University Here at Liverpool University a number of students are doing project work involving Hypercard. One of the projects involves the writing of reaction timing stacks. What I would like to know is: 1) is it possible to write an XCMD/XFCN to await a keypress and to time more accurately than 1/60th of a second, and return this info to a script. 2) One of the reaction timing stacks is supposed to play a sound on a background of white noise. Can an XCMD/XFCN play noise + a simple tone and do (1) above? I've written some Mac programs (nothing good enough to post) but I've never tried to write any XCMDs/XFCNs.
