simple tool to draw zones faster

if it works it works..

1) ZoneBuilder class can be final since you're using a singleton approach.

2) addPoint method can be simplified to this:

 

public void addPoint(Player player, Location loc)
{
	LinkedList<Location> locs = map.get(player);
	if (locs == null)
	{
		locs = new LinkedList<>();
		map.put(player, locs);
	}
  
	locs.add(loc);
}

 

3) You should use a singleton holder approach as

 

private static ZoneBuilder instance;

 

should be final. Check similar classes in your source.
