sorry line 6 is the 56th line in the class
Then you must have set the minimum value equal to the maximum value, which produces a difference of zero, causing the error.
I did not think that was possible. You must be by-passing the methods supplied in the Bar class to set the values or you set the default minimum and maximum fields to the same value.
here is a copy of my worlds instance field, constructor, and act method
public class Mw extends World
{
public static int life;
Bar bar = new Bar("", "Health", 20, 20);
Bar scoreBar = new Bar("Score", "points", 0, roundScore);
public static int score;
public Counter counter;
public static boolean canMove;
public static int money;
public static int roundScore;
public static int round;
/**
* Constructor for objects of class Mw.
*
*/
public Mw()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(1100, 550, 1);
life = 20;
score = 0;
prepare();
money = 0;
round = 1;
canMove = true;
roundScore = 500;
upRound();
counter = new Counter();
addCounter();
public void act()
{
randomAddAnts();
endScreen();
addRoundOver();
bar.setValue(life);
scoreBar.setValue(score);
}
}You are creating the scoreBar object before setting 'roundScore' to 500, meaning 'roundScore' is still zero.
Remove line 31 and move line 14 to before line 5, changing it to
public static int roundScore = 500;
thanks
