NAME
calibrate_joystick - Calibrates the specified joystick. Allegro game programming library. SYNOPSIS
#include <allegro.h> int calibrate_joystick(int n); DESCRIPTION
Most joysticks need to be calibrated before they can provide full analogue input. This function performs the next operation in the calibra- tion series for the specified stick, assuming that the joystick has been positioned in the manner described by a previous call to cali- brate_joystick_name(), returning zero on success. For example, a simple routine to fully calibrate all the joysticks might look like: int i; for (i=0; i<;num_joysticks; i++) { while (joy[i].flags & JOYFLAG_CALIBRATE) { char *msg = calibrate_joystick_name(i); textprintf_ex(..., "%s, and press a key ", msg); readkey(); if (calibrate_joystick(i) != 0) { textprintf_ex(..., "oops! "); readkey(); exit(1); } } } RETURN VALUE
Returns zero on success, non-zero if the calibration could not be performed successfully. SEE ALSO
