Question

I need to create a maze in Java where each time (i.e. every time I run the program ) a different maze would be made .
The program consists of 3 levels : beginner (25 rooms) , advanced (40 rooms) and expert (60 rooms) , with players (up to 20 players) and treasures , where each player must get at least one treasure .

I’ve made the logic side of the maze , meaning , I’ve written the maze algorithm where
each time the program randomly get a dot in the (x,y) plane and adds it to a graph – G=(V,E) – where the vertices are the rooms , and the edges are connectors (Door/Wall) .

Now my problem , is that I need to represent the maze using GUI , so I’ve attached the SWT from the Eclipse’s site to my program , but I do not know how to use the GUI to describe the maze/graph .

At first, I want to present to the user the maze before that game begins , meaning is , after creating the maze , before the players hit the road .

Can you please give me a hint where or how to start ?

the relevant classes are :

public class Room {



    private ArrayList<Connector> connectors;
    private int x;    // x coordinate of the room 
    private int y;    // y coordinate of the room 


    // constructor  

    Room(int xCoordinate,int yCoordinate)
    {
        //this.connectors = new HashMap<String,Connector>();
        this.connectors = new ArrayList<Connector>();
        this.x = xCoordinate;
        this.y = yCoordinate;
    }

    Room()
    {
        this.x = 0;
        this.y = 0;
    }


    public void addConnector(Connector connector)

    {
        this.connectors.add(connector);
    }

    /* Getters and Setters */

    public int getXcoordinate() 
    {
        return this.x;
    }

    public int getYcoordinate()
    {
        return this.y;
    }

    public void setXcoordinate(int newX)
    {
        this.x = newX;
    }

    public void setYcoordinate(int newY)
    {
        this.y = newY;
    }



}




package model;

public class Door extends Connector {


    // holds private Room[] rooms = new Room[2];

    Door(Room room1,Room room2) 
    {
        super(room1,room2);

    }

    public Room getNextRoom(Room room) 
    {
        if(this.rooms[0].equals(room))
        {
            return this.rooms[1];
        }
        return this.rooms[0];
    }


}


public abstract class Connector {


    protected Room[] rooms = new Room[2];
    public abstract Room getNextRoom(Room room);

    public Connector(Room room1,Room room2)  // building a new connector that connects between two rooms s
    {
        rooms[0] = room1;
        rooms[1] = room2;
    }

    public Room getFirstRoom()
    {
        return this.rooms[0];
    }

    public Room getSecondRoom()
    {
        return this.rooms[1];
    }



}

Take a look at http://www.eclipse.org/articles/Article-SWT-graphics/SWT_graphics.html . You can draw lines, points, or any other geometry that you would need.
