    public void konami()
    {
        String key = Greenfoot.getKey();
        if (key != null)
        {
            if (konamiKeys[keyIndex].equals(key)) // is next key in sequence
            {
                if (++keyIndex == konamiKeys.length) // is last key in sequence
                {
                    //rCount = true;
                    //rCount = 1;
                    keyIndex = 0;
                }
            }
            else // not in sequence -- start over
            {
                keyIndex = 0;
            }

    }
 
    private int pngCount = 0 ;
    //public int rCount = 0;
    //public boolean rCount = false;
     
     
    public void delayCounting()
    {
 
        pngCount++;
 
        if(pngCount == 14)
        {
            pngCount = 0;
        }
    }
 
    void Rainbow()
    {
        if(rCount == true or rCount == 1){
            if(pngCount == 2)
            {
                setImage("ACO.png");
            }
            if(pngCount == 4){
                setImage("ACY.png");
            }
            if(pngCount == 6){
                setImage("ACG.png");
            }
            if(pngCount == 8){
                setImage("ACLB.png"); 
            }
            if(pngCount == 10){
                setImage("ACB.png");
            }
            if(pngCount == 12){
                setImage("ACP.png");
            }
            if(pngCount == 14){
                setImage("abenteurer.png"); 
            }
 
            if ((isTouching(Waechter.class)))
            {
                GameEnd myImage = new GameEnd ();
                World w = getWorld();
                w.addObject(myImage, 9, 9);
                myImage.setImage("GG.png");
                Greenfoot.stop();
            }
        }
    }
}
but now i want to use the int/boolean in another actor so when you typed the konami code the weachter is no longer able to (kill = toeten) the abenteurer but rCount is not a declared variable in the actor weachter so how can i access a Boolean/int From Another Actor Class public void Toeten() { if(rCount == false or rCount == 0){ if ((isTouching(Abenteurer.class))) { GameEnd myImage = new GameEnd (); World w = getWorld(); w.addObject(myImage, 9, 9); myImage.setImage("WG.png"); Greenfoot.stop(); } } }

i fund this but i dint know if it is the right thing for me to use and how to implement it https://www.greenfoot.org/topics/5738 <-- where i found the info If it is a single int and it is being held in a unique instance I would do something like

class ZZZ
{
private static int thatThingYouWant;
  
public void setThatThingYouWant(int val)
{
thatThingYouWant = val;
}
  
public int getThatThingYouWant()
{
return thatThingYouWant;
}
}
with it being a static member, you can read this value anywhere by: someint = ZZZ.getThatThingYouWant(); and you can set it by ZZZ.setThatThingYouWant(someint); This should be okay for straight forward linear processing.

public void setThatThingYouWant(int value)
{
    thatThingYouWant = value;
}

if (isTouching(Abenteurer.class))
{
    Abenteurer abenteurer = (Abenteurer)getOneIntersectingObject(Abenteurer.class);
    int value = abenteurer.getThatThingYouWant();
}

        return playerLives;
    }
 
    // to allow value to be set from elsewhere
    public void setplayerLives(int value)
    {
        playerLives = value;
 
    }
here the code in the actor enemy: public void dead() { if(isTouching(Game_End.class)){ getWorld().removeObject(this); playerLives--; } } Thanks

if (isTouching(Game_End.class){
    World world = getWorld(); // to retain reference to world (see next line comment)
    world.removeObject(this); // after this executes getWorld will return a 'null' value
    Player player = (Player)world.getObjects(Player.class).get(0); // get reference to player
    player.setPlayerLives(player.getPlayerLives()-1); // access and set player lives
}
