I'm making a semi-horror game called Ollie's Ordinary Orchard. It's about collecting apples and completing orders. But as time goes on, things get creepier.
I'm having trouble keeping a counter on the screen, because I'm using multiple worlds. The reason I'm using multiple worlds is because I'm using Danpost's portal code. The counter is keeping track of how many apples you have collected, and it keeps disappearing whenever you go to another world/screen. It also gives me an error as well. I don't know what to do and I would like help please.
Here is some code that I think would be important:
/**
*
* This is the "player class". You control Ollie and move around.
*
*/
public class Ollie extends Actor
{
private int timer;
private GreenfootImage walk1;
private GreenfootImage walk2;
private static GreenfootSound collect = new GreenfootSound("collect.mp3");
public Ollie()
{
walk1 = new GreenfootImage("ollieWalk.png");
walk2 = new GreenfootImage("ollieWalk2.png");
setImage(walk1);
}
/**
* The movement code here is all of @Danpost's code, it is not mine.
* I have just copied it. But the rest is my code.
*/
public void act()
{
int dx = 0, dy = 0;
if(Greenfoot.isKeyDown("W")) dy = -4;
if(Greenfoot.isKeyDown("A")) dx = -4;
if(Greenfoot.isKeyDown("S")) dy = 4;
if(Greenfoot.isKeyDown("D")) dx = 4;
setLocation(getX()+dx, getY()+dy);
if(isTouching(Tree.class))
{
setLocation(getX()-dx, getY()-dy);
}
if(isTouching(HouseHitbox.class))
{
setLocation(getX()-dx, getY()-dy);
}
if(isTouching(BridgeHitBox.class))
{
setLocation(getX()-dx, getY()-dy);
}
if(isTouching(PondHitBox.class))
{
setLocation(getX()-dx, getY()-dy);
}
animation();
pickApples();
}
public void pickApples()
{
Screen1 s1 = (Screen1) getWorld();
if(isTouching(apple.class))
{
collect.play();
removeTouching(apple.class);
s1.applesPicked.add(1);
}
}

if(timer == 10)
{
