I am making pac man ( i am quite new to greenfoot so i want to learn, so i decided to by making pacman) I want to add walls so that pacman cannot pass through them (stops at the walls) Here is my pacman code 
import greenfoot.*;

/**
 * Write a description of class PacMan here.
 * 
 * @author (your name) 
 * @version (a version number or a date)
 */
public class PacMan extends Actor
{
    /**
     * Act - do whatever the PacMan wants to do. This method is called whenever
     * the 'Act' or 'Run' button gets pressed in the environment.
     */
    public void act() 
    {
        if (Greenfoot.isKeyDown("up"))
        {
            setRotation(0);
            turn(-90);
            move(5);
        }
        if (Greenfoot.isKeyDown("down"))
        {
            setRotation(0);
            turn(90);
            move(5);
        }
        if (Greenfoot.isKeyDown("left"))
        {
            setRotation(0);
            turn(0);
            move(-5);
        }
        if (Greenfoot.isKeyDown("right"))
        {
            setRotation(0);
            turn(0);
            move(5);
        }
    }    
}
I just want PacMan to not be able to pass through walls (that you add in, which i dont know how to do so if you could help me with that, that would be nice) Thanks

In my Pac-Man game, I saved the map as an array in the world, so Pac-Man can check if there is a "wall" on the side. You can download the game and check the code. The alternative is to have walls as actors in the world. Then Pac-Man can move, and if it hits a wall, you place it back to where it came from.
