Play a sound whenever the crab turns more than 18 degrees.
I know how to add a sound, but how do I make the sound from a turn? I can not recall.

make sound when turning a certain amount?
public class Crab extends Actor

Greenfoot.playSound("slurp.wav");

public void moveAround()

turn(Greenfoot.getRandomNumber(91)-45);
}
}
THIS IS WHAT I HAVE SO FAR
You have:
Try this:
I have the feeling that you will hear that sound quite often though.
turn(Greenfoot.getRandomNumber(91)-45);
int turningAmount = Greenfoot.getRandomNumber(91)-45;
turn(turnAmount);
if (turnAmount>18 || turnAmount<-18)
{
//play a sound
}
