The Actor method getNeighbours() gives strange results in certain situations.
import greenfoot.*;
public class DotWorld extends World {
public DotWorld(){
super( 10, 10, 60 );
for( int y=0; y<getHeight(); y++ ) {
for( int x=0; x<getWidth(); x++ ) {
addObject( new Dot(), x, y );
}
}
}
}import greenfoot.*;
public class Dot extends Actor {
public Dot() {
setImage( "yellow-draught.png" ); // results depend on the image (!)
}
public void act() {
int n = getNeighbours( 1, false, null ).size(); // wrong count for certain combinations of world.cellsize and size of actor image
// int n = getObjectsInRange( 1, null ).size(); // works
getWorld().showText( Integer.toString( n ), getX(), getY() );
}
}
