Using the User32.dll library, GetKeyState(), the Pause/Break key acts like a switch. the switch can then be checked repetitiously in a loop for changes. The only complication, is that the Pause/Break key 'switch' may already be turned ON prior to running the program, or as a result of exiting a 'paused' game. This entails an initial setting to reflect the state of the key, and store it as adefault non-paused value. The code requires a .decls file with the following declaration: .Lib "user32.dll" GetKeyState% (nVirtKey%) : "GetKeyState" Place these lines into a text file, and save it as "user32.decls" in the userlibs folder. | |||||
