I have built a code for health, food and water using encapsulation but I don' know how to initialize the variable reference for each asset.
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 | import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Heart2 here. * * @author (your name) * @version (a version number or a date) */ public class HealthGirl extends Actor { /** * Act - do whatever the Heart2 wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ private int healthG = 30 ; private GreenfootImage imagem; public int getHealthG(){ return healthG; } public void setHealthG( int hg){ healthG = hg; } public void addHealthG( int hg){ healthG += hg; } public void removeHealthG( int hg){ healthG -= hg; } public HealthGirl(){ } public void act(){ if (getHealthG() <= 0 ){ setHealthG( 0 ); } imagem = getImage(); imagem.setTransparency( 255 *getHealthG()/ 100 ); } } |
