Hey. I would like to make my actor not protrude world edge. It kinda goes halfway and then it blocks the move input. I kinda feel this is easy, but I can´t find anything online. Thanks! 
import greenfoot.*;  // (World, Actor, GreenfootImage, Greenfoot and MouseInfo)


public class Kosik extends Actor
{
   
    final String MoveLeft="Left";
    
    final String MoveRight="Right";
    
    public int movement=10;
    public void act() 
    
    {
                if(Greenfoot.isKeyDown(MoveLeft)){
            move(-movement);
        }
                if(Greenfoot.isKeyDown(MoveRight)){
            move(movement);
        }
    }    
}

The actor's image is centered at its location. Use actor's location and the width of its image to adjust location of actor when too close to an edge (after a move).

OK. I somehow figured it out! Thanks, your reply helped me get to the bottom of it ;)

            move(-movement);
            if (getX()<70){
                setLocation(70, 577);
            }
        }
   
                if(Greenfoot.isKeyDown(MoveRight)){
            move(movement);
            if(getX()>730){
            setLocation(730, 577);
        }
    
}
}
}
