Hello! I was wondering how to make a button that when i press it i add +1 point to a variable. It seems very simple i know but i just can't figure out how to do it! Also how do i display the number in a terminal window? or as text on screen? Thanks very much! - Gaming_100

//in an Actor subclass, the button
private int counter = 0;
 
public void act()
{
    if (Greenfoot.mousePressed(this))
    {
        counter++;
        //display text
    }
}
To print it to the terminal window, you can use:
?
1
System.out.println("Counter = " + counter);
To make it visible in the world, you can either use the showText method in the world
?
1
getWorld().showText("Counter = " + counter, 100, 100);
or you have an actor, give it an image with the value of the variable and add it to the world.
