I'm trying to make a cookie clicker game and made it so that when you hit one of the smaller cookies, it subtracts points from your score. I was wondering if its possible to prevent it from going below zero and just stop there instead.
This is my counter code:
And this is the smaller cookie code that will subtract points:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 | import greenfoot.*; // (World, Actor, GreenfootImage, and Greenfoot)import java.awt.Graphics;/** * Counter that displays a number with a text prefix. * * @author Michael Kolling * @version 1.0.2 */public class Counter extends Actor{ private static final Color textColor = new Color(255, 180, 150); private int value = 0; private int target = 0; private String text; private int stringLength; private int totalCount = 100; public Counter() { setImage(new GreenfootImage("0", 20, Color.WHITE, Color.BLUE)); } public void updateImage() { setImage(new GreenfootImage("" + value, 20, Color.WHITE, Color.BLUE)); } public void act() { if(value < target) { value++; updateImage(); } else if(value > target) { value--; updateImage(); } } public void add(int score) { target += score; } public void subtract(int score) { target -= score; } public int getValue() { return value; }} |

This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { move(4); if(getY()>=598){ getWorld().removeObject(this); } if (Greenfoot.mouseClicked(this)==true) { BackGround theWorld = (BackGround) getWorld(); // get a reference to the world Counter counter = theWorld.getCounter(); // get a reference to the counter counter.add(-5); } }} |
