Map design

The following class diagram (Figure 5) shows the top-level architecture for handling the loading of multiple maps and their corresponding entities:

Here, we first start with the MapFactory class, which can be found at core/src/com/packtpub/libgdx/bludbourne/MapFactory.java, with the source code as follows:

package com.packtpub.libgdx.bludbourne;

import java.util.Hashtable;

public class MapFactory {
    //All maps for the game
    private static Hashtable<MapType,Map> _mapTable = new Hashtable<MapType, Map>();

    public static enum MapType{
        TOP_WORLD,
        TOWN,
        CASTLE_OF_DOOM
    }

    static public Map getMap(MapType mapType){
        Map map = null;
        switch(mapType){
            case TOP_WORLD:
                map = _mapTable.get(MapType.TOP_WORLD);
                if( map == null ){
                    map = new TopWorldMap();
                    _mapTable.put(MapType.TOP_WORLD, map);
                }
                break...
