Hello Greenfoot Wizards, I need some help displaying a variable in the world. I know that I need to do it with an actor, and I know how to do that with static text, But I don't know how to do it when it's a variable. The variable is "Timer", which is in the World class ("Haven"). I created a class named "Tijd" If it's easier to display a variable that is in the same class, than that would be fine too. so I also created a variable named Timer2 which holds the same value.

int smalltimer = 0; 
       
    /**
     * Act - do whatever the Tijd wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */ 
    public void act()  
    { 
        int timer2 = ((Haven)getWorld()).timer; 
      
           
    }
My question is, how can I display a variable (that of course keep showing the correct value in"Timer or Timer2") ? I plan to use the class "Tijd" just for that. Any help is highly appreciated.

When you already have the right value of the variable you just need to set the actors image to that variable:

public void act() {   
    int timer2 = ((Haven)getWorld()).timer;   
    setImage(new GreenfootImage(""+timer2, 35, null, null);
    //this will make the actors image become the value of timer2 with a fontsize of 35, a black text color and a transparent background color.
   // you can also change this settings by changing the parameters 35, null, null;
}

Thanks, that worked. I did know how to display a string in greenfoot, but simple replacing the string with an variable strangely doesn't work. But I see that adding a variable to an ( In this case) empty string does work, So thanks again, also for the quick reply.
