THis all goes into the world class right? private LevelMeter levelMeter = new LevelMeter(); // in constructor addObject(levelMeter, someX, someY); // public getter method public LevelMeter getLevelMeter() { return levelMeter; }

this is the code off the MiniGame2... which makes up the MINIGame2World..and do i insert the code there where i made the text bold and italic? public class MiniGame2World extends World { GameState globalGameState; MG2Ship ship; /** * Constructor for objects of class MiniGame2World. * */ public MiniGame2World() { // Create a new world with 600x400 cells with a cell size of 1x1 pixels. super(1280, 720, 1, false); prepare(); } public void setGameState(GameState gamestate) { this.globalGameState = gamestate; } public GameState getGameState() { return this.globalGameState; } private void prepare() { MG2Quay quay = new MG2Quay(); addObject(quay, 640,680); MG2Train train = new MG2Train(); addObject(train,1100,620); this.ship = new MG2Ship(this); addObject(ship,400,615); MG2Hook hook = new MG2Hook(); addObject(hook,450,-250); private LevelMeter levelMeter = new LevelMeter(); // in constructor addObject(levelMeter, someX, someY); // public getter method public LevelMeter getLevelMeter() { return levelMeter; } } public void act() { buttonPressed(); } public void buttonPressed() { if(Greenfoot.isKeyDown("escape")) { int n = JOptionPane.showConfirmDialog(null, "Do you really want to exit to the main menu?", "Exit", JOptionPane.YES_NO_OPTION); if (n == 0) { MainMenuWorld newWorld = new MainMenuWorld(); newWorld.setGameState(this.getGameState()); Greenfoot.setWorld(newWorld); } } } public MG2Ship getShip() { return this.ship; } public void win() { int n = JOptionPane.showConfirmDialog(null, "You won! Do you want to go to minigame 3?", "Winner!", JOptionPane.YES_NO_OPTION); this.getGameState().setFinished(2, 0); if (n == 0) { MiniGame3World newWorld = new MiniGame3World(); newWorld.setGameState(this.getGameState()); Greenfoot.setWorld(newWorld); } else { MainMenuWorld newWorld = new MainMenuWorld(); newWorld.setGameState(this.getGameState()); Greenfoot.setWorld(newWorld); } } }

Yes. Only the 'addObject' line goes there in the 'prepare' method. The rest goes inside the class but outside any existing methods or constructors. You will have to replace 'someX' and 'someY' in the addObject line with valid coordinate values.

1.how can i adjust the space between arrow and gauge? 2.so what do i do to get the arrow moving if i remove a container? i thought it would move with the code: public void act() { if (balance*15 > getRotation()) turn(1); if (balance*15 < getRotation()) turn(-1); }

Add or subtract some from the 'getY' part of the 'world.addObject' statement in the 'addedToWorld' method of the LevelMeter class. You need to call the 'setBalance' method of the LevelMeter class from the Ship class when a container is added or removed. For example:

okay so i got the adjusting down!! now for the calling of setBalance how do i apply it so that it works? i've put it in the LevelMeter class under the public void setBalanance method but it didnt work, then i tried it under the public void Act no success. i dont see the connections yet therefore the question i ask.

No need for a 'setBalanance' (or 'setBalance') method in the LevelMeter class; and, it does not go in the act method itself. The last line I gave you goes at the end of both the 'addContainer' and 'removeContainer' methods.

public void removeContainer(MG2Container container) { for(int i=0; i < this.containers.length; i++){ for(int i2=0; i2 < this.containers.length; i2++){ if (this.containers != null && container == this.containers) { this.containers = null; break; } } } ((MiniGame2World)getWorld()).getLevelGauge().setBalance(balance); } i inserted it at the end of the code both the addcontainer and removecontainer and it gives me a cannot find symbol - variable balance error.

The above, earlier in this discussion, was about the balance state of the Ship object.

It is the balance of the Ship object that the meter is to display -- yes.

public class LevelGauge extends Actor { GreenfootImage MG2Arrow = new GreenfootImage("MG2Arrow.png"); // adjust name as needed GreenfootImage MG2Meter = new GreenfootImage("MG2Meter.png"); // adjust name as needed int balance; public LevelGauge() { GreenfootImage img = MG2Meter; img.scale(img.getWidth()*3/4, img.getHeight()*3/4); img = MG2Arrow; img.scale(img.getWidth()/2, img.getHeight()/2); setImage(MG2Arrow); } public void addedToWorld(World world) { Gauge gauge = new Gauge(); gauge.setImage(MG2Meter); world.addObject(gauge, 390,305); } public void setBalance(int bal) { balance = bal; So I Figure that the formula goes here what is the full formula for this balance of the Ship object } /** * Act - do whatever the LevelGauge wants to do. This method is called whenever * the 'Act' or 'Run' button gets pressed in the environment. */ public void act() { if (balance*15 > getRotation()) turn(1); if (balance*15 < getRotation()) turn(-1); // Add your action code here. }
