Hi Bob, I did use floating point numbers by using 4.0/1.0 - 4.0/3.0 etc., though I did not declare it explicitly. Do you think it's better form/practice to explicitly declare it? Regards, Sagar On Mon, Oct 17, 2011 at 9:10 PM, bob gailer bgai...@gmail.com wrote: On 10/17/2011 6:31 AM, Sagar

So use raw wx key events. They include key down,up and press events. I'll give this a shot. Thank you. Bloated carries the connotation of unnecessary code, but pygame provides a lot of functionality. You may not need it all, and using pygame may require you to import more than you need. But
