In my game, I need a scoring system but I'm not entirely sure how to create one. Could somebody please give me some advice. Thanks.

How to make a scoring system?
In your case, since you are using a game over world and presuming that you have multiple players, you could use something like this in your world class (written for two players, but easily modifiable for more):
With the above in a MyWorld world, from an Actor subclass, you can
public static final RED = 0, BLUE = 1; // continue for more players
private int[] scores = new int[2]; // size to number of players
public int getScore(int player)
{
return scores[player);
}
public void addScore(int player, int amount)
{
scores[player] += amount;
}
public int[] getScores()
{
return scores;
}// get a single score int redScore = ((MyWorld)getWorld()).getScore(MyWorld.RED); // add to a score ((MyWorld)getWorld()).addScore(MyWorld.BLUE, 10); // or get both scores int finalScores = ((MyWorld)getWorld()).getScores();
What I usually do is this to show the scoreboard in the world. (Put this in your "My World" class)
Here's how you would add the score (Put this in your ammunition class or whatever would touch the enemy to add score)
private int score = 0;
public int time = 0;
/**
* Constructor for objects of class MyWorld.
*
*/
public MyWorld()
{
// Create a new world with 600x400 cells with a cell size of 1x1 pixels.
super(1100, 600, 1);
GreenfootImage back = getBackground();
back.setColor(Color.BLACK);
back.fill();
prepare();
showScore();
score++;
}
public void act()
{
countTime();
}
public void countTime()
{
time++;
}
public void addScore(int points)
{
score = score + points;
showScore();
}
public void showScore()
{
showText("Ship 1: " + score, 75, 25);
}public void Stuff()
{
boolean kill = true;
if(kill)
if (isTouching(UFO.class))
{
kill = false;
removeTouching(UFO.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
Greenfoot.playSound("Explosion copy.wav");
world.addScore(50);
}
if(kill)
if (isTouching(Arwing.class))
{
kill = false;
removeTouching(Arwing.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
Greenfoot.playSound("Explosion copy.wav");
world.addScore(-50);
}
if(kill)
if (isTouching(UFO0.class))
{
kill = false;
removeTouching(UFO0.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
Greenfoot.playSound("Explosion copy.wav");
world.addScore(50);
}
if(kill)
if (isTouching(Mario.class))
{
kill = false;
removeTouching(Mario.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
world.addScore(200);
Greenfoot.playSound("Mario 64 Falling Death Scream (320 kbps).mp3");
}
if(kill)
if (isTouching(Mario2.class))
{
kill = false;
removeTouching(Mario2.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
world.addScore(200);
Greenfoot.playSound("Mario 64 Falling Death Scream (320 kbps).mp3");
}
if(kill)
if (isTouching(Arwing1.class))
{
kill = false;
removeTouching(Arwing1.class);
MyWorld world = (MyWorld)getWorld();
getWorld().addObject(new Explosion(), getX(), getY());
getWorld().removeObject(this);
Greenfoot.playSound("Explosion copy.wav");
world.addScore(-50);
}
}Its a one player game and I am very confused at the lines of code there is. So many some more clarification of what the ifs and other stuff are doing. Thanks

public int getScore()
{
return score;
}
public void addScore(int amt)
{
score += amt;
}// getting score int score = ((MyWorld)getWorld()).getScore(); // changing score ((MyWorld)getWorld()).addScore(10);
After i put this code in, my bullet won't shoot. Also where do i put the changing score bit?

In whatever Actor subclass whose instances get hit to score points.OK i fixed the shooting but the score doesn't go up

GreenfootImage g = new GreenfootImage("beeper.png");
g.scale(50, 50);
setImage(g);
}
public void act()
{
int score = ((MyGame)getWorld()).getScore();
Actor t;
t = getOneObjectAtOffset(0, 0, Igloo.class);
setLocation(getX() + 50, getY());
if(t!=null)
{
((MyGame)getWorld()).addScore(1);
World w = getWorld();
w.removeObject(t);
getWorld().removeObject(this);
}
else if(isAtEdge())
{
getWorld().removeObject(this);
}
}
How do you know that the score isn't increasing? Did you inspect the MyGame instance?
My guess is that the bullet is moving too fast. Chances are the bullet is moving through the Igloo without actually touching it.
Its alright i've fixed it now thanks guys
