Im trying to make it so i have a day counter in the top corner of my screen. Im trying to make it so when the user clicks on an object, the dayValue is increased by one and this is displayed. This is what i have for the code so far but it is not working. This is in the BeeWorld World.

  
  public int dayValue;
  public void addDay()
    {
        if(Greenfoot.mouseClicked(null))
        {
            Actor actor = Greenfoot.getMouseInfo().getActor();
            if(actor != null)
            {
                dayValue = dayValue + 1;           
            }
        }    
    }

Looks to me like the code would work for counting clicks on Actor objects. However, I do not see any codes given for displaying the value. Nor do I see where this method is called from.

ive changed where i put it and added some more but it still isn't working, this is what i added. In the AddDay class:

    public void addDay()
    {
        if(Greenfoot.mouseClicked(this))
        {
           BeeWorld beeWorld = (BeeWorld) getWorld();
           beeWorld.update();                     
        }    
    }

and in the BeeWorld class

    public void update()
    {
        //update what day it is and run the next day when the day button is clicked
        dayValue = dayValue +1;
        showText("Day: " + dayValue, 810, 50);
        newDay();
    }
    
    public void newDay()
    {
        //start new day
    }

public class AddDay extends Actor
{  
    public AddDay()
    {
       //Set image of button
       setImage(new GreenfootImage("addDaybutton.png"));
    }
    
    public void act()
    {
        //check if the button is being pressed
        addDay();
    }
    
    public void addDay()
    {
        if(Greenfoot.mouseClicked(this))
        {
           BeeWorld beeWorld = (BeeWorld) getWorld();
           beeWorld.update();                     
        }    
    }
}

this is where i am calling the method

Maybe you are not being very clear. From what I see the counter will show up and will increment once the button is clicked. However, before the button is clicked, you will not have a visible counter unless you add the following method to the AddDay class:

protected void addedToWorld(World world)
{
    ((BeeWorld)world).update();
}

Declare the dayValue field in the BeeWorld class initialized at zero:

private int dayValue = 0;
// or just
private int dayValue;

There is none at the moment, as i am only trying to make the counter for the day increase by one for now

From what I can tell, the displayed value should increase when the AddDay actor is clicked. Might there be another actor on top of the AddDay actor that is getting the clicks instead?

Theres no actors above it im not sure if ive messed something up in the add day class this is the code for it:

public class AddDay extends Actor
{ 
    private int dayValue = 0;
    public AddDay()
    {
       //Set image of button
       setImage(new GreenfootImage("addDaybutton.png"));
    }
    
    public void act()
    {
        //check if the button is being pressed
        addDay();
    }
    
    public void addDay()
    {
        if(Greenfoot.mouseClicked(this))
        {
           BeeWorld beeWorld = (BeeWorld) getWorld();
           beeWorld.update();                     
        }    
    }
    
    protected void addedToWorld(World world)
    {
        ((BeeWorld)world).update();
    } 
}

The only thing "wrong" here is line 3, which can be removed. That field should already be in your BeeWorld class.

Not sure what you mean by "anywhere"? Only as above would be sufficient. It was placed into your AddDay class to initialize the display, which could not be done until the AddDay object was created and added into a world.
