    Default GUI Problem

    i417.photobucket.com/albums/pp260/spawnacreature/Opoly.jpg

    i need to know how to make the blue boxes, i need to set the size of board to 21.

    also how would i get the postions to cycle through and when it reaches the end to say game over in red.
    anyhelp would be apreciated
    this is what i have so far it works. I have it set up to look like the picture just doesnt do anything

    i just dont know what to add, to get the numbers to show up next to the rewards and postion or also the blue squares

    and help would be very apreciated.

    The game cant change this file...

    }

    if(pos%4==0) reward = 2*reward;
    }
    }
     
    public boolean isGameOver(){

    return (pos==boardSize);
    }

    // does a spin, then move
    int p=spin();
    move(p);
    }
     
    public void drawBoard(){
    // a crude drawing of the board; shows current reward
    for(int j=0; j<boardSize; j++){
    if(j!=pos){

    else{
    System.out.print("o");}
    }

    Display window

    c.add(p);
    }

    Default Re: GUI Problem

    First, your OpolyPanel class extends JPanel, so there is no super.Opoly2(25). Might be better to create an instance variable of Opoly2 in your OpolyPanel class, this way your drawing can easily interact with it for drawing and interaction.

    For drawing the squares similar to the image you provided, you need to override the paintComponent method of the panel you are going to draw to and draw the squares. Its a trivial drawing problem from there (read up on 2D Graphics in java)
