Hey you guys. I was wondering how do i use a health code in another actor Add Exp in my main one. For source here are the two actors Main Actor (Protag) import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) import java.awt.Font; import java.awt.Color; import java.util.List; /** * Write a description of class Protag here. * * @author (your name) * @version (V1 - No working Exp System) */ public class Protag extends Actor { private Wolf Wolf; private int WolfHP = 0; public int ExpCount_; public int Lvl; public int HP; private GreenfootImage image1; private GreenfootImage image2; private GreenfootImage image3; private int animationcount = 0; int FireDelay = 10; int soundPlay = 0; int InvFrames = 30; public Protag() { super(); ExpCount_ = 0; image1 = new GreenfootImage("Hero2.png"); image2 = new GreenfootImage("Hero3.png"); image3 = new GreenfootImage("Hero.png"); setImage(image3); } /** * Act - do whatever the Protag wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { keyboard(); animaion(); checkFire(); LevelUp(); getWolfHP(); Health(); } public void keyboard() { int y = getY(); int x = getX(); if (Greenfoot.isKeyDown("d")) { setLocation(x+4,y); animationcount ++; setRotation(0); } if (Greenfoot.isKeyDown("a")) { setLocation(x-4,y); animationcount ++; setRotation(180); } if (Greenfoot.isKeyDown("s")) { setLocation(x,y+4); animationcount ++; setRotation(90); } if (Greenfoot.isKeyDown("w")) { setLocation(x,y-4); animationcount ++; setRotation(270); } } public void animaion() { if(animationcount >= 20) { setImage("Hero2.png"); } if(animationcount >= 40) { setImage("Hero3.png"); animationcount = 0; } } public void checkFire() { if(Greenfoot.isKeyDown("x")){ ExpCount_ ++; } if(Greenfoot.isKeyDown("space")) { FireDelay ++; } if(FireDelay >= 35) { getWorld().addObject(new Sword(getRotation()), getX(), getY()); FireDelay = 0; } } public void Health() { Actor a = getOneIntersectingObject(Wolf.class); if(a!= null) { InvFrames--; } if(InvFrames <= 0) { HP = HP - 4; InvFrames = 30; } } public int getExpCount() { return ExpCount_; } public int getLvl() { return Lvl; } public int getHP() { return HP; } public void LevelUp() { if(ExpCount_ >= 0) { Lvl = 1; } if(ExpCount_ >= 100){ Lvl = 2; } if(ExpCount_ >= 200){ Lvl = 3; } if(ExpCount_ >= 300){ Lvl = 4; } if(ExpCount_ >= 400){ Lvl = 5; } if(ExpCount_ >= 500){ Lvl = 6; } } public void level() { if(Lvl == 2 && ExpCount_ == 100) { HP = 20; } if(Lvl == 3 && ExpCount_ == 200) { HP = 30; } if(Lvl == 4 && ExpCount_ == 300) { HP = 40; } if(Lvl == 5 && ExpCount_ == 400) { HP = 50; } if(Lvl == 6 && ExpCount_ == 500) { HP = 60; } } public int getWolfHP() { int WolfHP = ((getWolf()).getWorld().getObjects(Wolf.class).get(0)).getWolf; /*if(WolfHP <= 0) { XP = XP + 100; }*/ } } Wolf import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) import java.util.List; /** * Write a description of class Wolf here. * * @author (your name) * @version (a version number or a date) */ public class Wolf extends Actor { public int Wolf = 4; int InvFrames = 3; int spawn = 0; public void act() { Dmg(); move(2); } public void Dmg() { Actor Sword = getOneIntersectingObject(Sword.class); if(Sword!= null){ InvFrames --; } if (InvFrames <= 0){ Wolf = Wolf - Greenfoot.getRandomNumber(2)-4; InvFrames = 3; } if(Wolf <= 0){ getWorld().removeObject(this); } } public int getWolf() { return Wolf; } } Oh also have 3 working counters in Protag and the world Thanks any help would be appreciated this is giving me a headache.
