Hey, I'm having troubles trying to call some of the methods in "Scoreboard subclass" to my "Person subclass". I manage to do it passing a parameter in the constructor of "Person (<parameter>)" and a couple of other things, but I need to call those methods without having a parameter in the constructor (Person). So, What I'm going after is having no parameter in "Public Person()" but to use the methods inside the subclass Scoreboard.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | public class MyWorld extends World {private Scoreboard tab;public MyWorld(){ // Create a new world with 800x600 cells with a cell size of 1x1 pixels. super(800, 600, 1); tab = new Scoreboard(); // creates the Scoreboard addObject(tab, 399, 10); // add the Scoreboard to the World Person player = new Person(tab) ; // creates a new player addObject(player, 2,580); // add the player to the World Spider Enemy = new Spider(); // create a new Spider object addObject(Enemy,Greenfoot.getRandomNumber(getWidth()),54); // add the object to the world } |
