Sharp IR error

Dear Arduino friends,

I have a Sharp GP2YA41SK0F IR sensor connected to my Arduino Uno and I am getting an error saying ‘class SharpIR’ has no member named ‘distance’ (please see copied error message below).

It worked a couple weeks ago when I first tested it, but now this error. Does anyone have a suggestion as to what may be causing this?

(The code I am trying to load is below the copied error message)

(Copied error message)

(Code I am trying to load)

#include <SharpIR.h>

#define ir A0
#define model 430
// ir: the pin where your sensor is attached
// model: an int that determines your sensor: 1080 for GP2Y0A21Y
// 20150 for GP2Y0A02Y
// (working distance range according to the datasheets)

SharpIR SharpIR(ir, model);

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}

void loop() {
delay(2000);

unsigned long pepe1=millis(); // takes the time before the loop on the library begins

int dis=SharpIR.distance(); // this returns the distance to the object you’re measuring

Serial.print("Mean distance: "); // returns it to the serial monitor
Serial.println(dis);

unsigned long pepe2=millis()-pepe1; // the following gives you the time taken to get the measurement
Serial.print("Time taken (ms): ");
Serial.println(pepe2);

}

So, why do YOU think the class has a member named distance()?

Post a link to the library, so wen can see what members it does have.
