I'm very new to greenfoot and I am supposed to get a thing to move when i press a certain key. When I write this code below the thing moves without me pressing any key, it just doesn't react to me pressing it. What have done wrong? import greenfoot.*; // (World, Actor, GreenfootImage, Greenfoot and MouseInfo) /** * Write a description of class Banan here. * * @author (your name) * @version (a version number or a date) */ public class Banan extends Mat { public void act() { checkKeypress(); } public void checkKeypress() { if(Greenfoot.isKeyDown("left")); { setLocation(getX()+1, getY()); } if(Greenfoot.isKeyDown("right")); { setLocation(getX(), getY()); } }

here you go, 
public void act() 
    {
        checkKeypress();
    }

    public void checkKeypress()
    {
        if(Greenfoot.isKeyDown("left"))
        {
            setLocation(getX()+1, getY());

        }
        if(Greenfoot.isKeyDown("right"))
        {
            setLocation(getX()-1, getY());

        }  
    }

your welcome, the semi colons at the end of if statements signal the end of the statement, and the other code is run without any keys pressed.
