Original Game

String name= "Pepper"; // hard code name for example
int place=1; //place is the position on the game board

Board Creation - new class
Create a class that has a method to draw your
game. It needs to know the location of your piece.
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board =
AImage.makeRectangle(500,500, Color.yellow,
Mode.solid);
return board;
} }

See the Board - change game
Add a canvas:
import javalib.worldcanvas.*;
import java.util.Scanner;
public class Game {
public static void main() {
WorldCanvas gameSpace = new WorldCanvas(500,500,"game place") ;
Scanner scan=new Scanner(System.in);
String name= "Pepper"; // hard code name for example
int place=1; //place is the position on the game board
gameSpace.show();
gameSpace.drawImage(MyWorld.drawGame(place));
for(int turn=1; turn<=10; turn++)
{ int sum=diceThrow(name); // returns value of 2 dice
place=movePlayer(name, place, sum); // returns new location of player
}
System.out.println("You are now on square "+place + " GAME IS DONE.");
}

Start Board Drawing
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board = AImage.makeRectangle(500,500, Color.yellow, Mode.solid);
// Create a vertical and horizontal line
WorldImage horizLine = AImage.makeLine(new Posn(0,0),new Posn(500,0));
WorldImage verticalLine = AImage.makeLine(new Posn(0,0),new Posn(0,500));
// See how it looks with the center of horizontal at 250,50 and vertical at 50/250
board = board.place(horizLine,250,50);
board = board.place(verticalLine,50,250);
return board;
} }
Finish Board Picture
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board = AImage.makeRectangle(500,500, Color.yellow, Mode.solid);
WorldImage horizLine = AImage.makeLine(new Posn(0,0),new Posn(500,0));
WorldImage verticalLine = AImage.makeLine(new Posn(0,0),new Posn(0,500));
for (int count = 50; count <= 500; count= count + 50){
board = board.place(horizLine,250,count);
board = board.place(verticalLine,count,250);
}
return board;
} }
Add Player - Place anywhere
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board = AImage.makeRectangle(500,500, Color.yellow, Mode.solid);
WorldImage horizLine = AImage.makeLine(new Posn(0,0),new Posn(500,0));
WorldImage verticalLine = AImage.makeLine(new Posn(0,0),new Posn(0,500));
for (int count = 50; count <= 500; count= count + 50){
board = board.place(horizLine,250,count);
board = board.place(verticalLine,count,250);
}
WorldImage hisPiece = AImage.makeCircle (10, Color.blue, Mode.solid);
WorldImage game = board.place(hisPiece, loc, loc) ;
return game;
} }
Put Player on correct square
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board = AImage.makeRectangle(500,500, Color.yellow, Mode.solid);
WorldImage horizLine = AImage.makeLine(new Posn(0,0),new Posn(500,0));
WorldImage verticalLine = AImage.makeLine(new Posn(0,0),new Posn(0,500));
for (int count = 50; count <= 500; count= count + 50){
board = board.place(horizLine,250,count);
board = board.place(verticalLine,count,250);
}
WorldImage hisPiece = AImage.makeCircle (10, Color.blue, Mode.solid);
WorldImage game = board.place(hisPiece, (loc%10)*50-25, loc/10*50+25) ;
return game;
} }
Game redraw and slow down
Add a canvas:
import javalib.worldcanvas.*;
import java.util.Scanner;
public class Game {
public static void main() {
WorldCanvas gameSpace = new WorldCanvas(500,500,"game place") ;
Scanner scan=new Scanner(System.in);
String name= "Pepper"; // hard code name for example
int place=1; //place is the position on the game board
gameSpace.show();
gameSpace.drawImage(MyWorld.drawGame(place));
for(int turn=1; turn<=10; turn++)
{ int sum=diceThrow(name); // returns value of 2 dice
place=movePlayer(name, place, sum); // returns new location of player
gameSpace.drawImage(MyWorld.drawGame(place));
System.out.println( " Press Enter to continue.");
scan.nextLine();
}
System.out.println("You are now on square "+place + " GAME IS DONE.");
}

Your Turn - Change your game
Goal: Just want to move a piece around an empty
board.
 Create a new class to draw called MyWorld
import javalib.worldimages.*;
import java.awt.Color;
public class MyWorld {
public static WorldImage drawGame (int loc)
{
WorldImage board =
AImage.makeRectangle(500,500, Color.yellow,
Mode.solid);
return board;
} }

Change your game to draw
Use your homework code and fill in the red and blue parts, or use my code to start :

import javalib.worldcanvas.*;
import java.util.Scanner;
public class Game {
public static void main()
{
WorldCanvas gameSpace = new WorldCanvas(500,500,"game place") ;
Scanner scan=new Scanner(System.in);
String name= "Pepper"; // hard code name for example
int place=1;
//place is the position on the game board
gameSpace.show();
gameSpace.drawImage(MyWorld.drawGame(place));
for(int turn=1; turn<=10; turn++)
{
int sum=diceThrow(name); // returns value of 2 dice
place=movePlayer(name, place, sum); // returns new location of player
gameSpace.drawImage(MyWorld.drawGame(place));
System.out.println( " Press Enter to continue.");
scan.nextLine();
}
System.out.println("You are now on square "+place + " GAME IS DONE.");
}
public static int diceThrow(String name)
{
return 12; // your diceThrow code will send back something better and print it.
}
public static int movePlayer(String name, int startPt, int numberToMove) {
System.out.println("You are now on square " + (( numberToMove + startPt ) %100));
return ( numberToMove + startPt ) %100;
}}
Code MyWorld drawGame method

Add any shaped piece to your board - ex:
WorldImage hisPiece = AImage.makeCircle (10,
Color.blue, Mode.solid);

Place the piece onto the board:
WorldImage game = board.place(hisPiece, loc,
loc) ;

Return game instead now
return game;

Change the piece to move as you please
by adjusting the piece's x and y
Summary
Know how to use WorldCanvas object
 Separated some drawing knowledge out
of your game class

◦ Called a method in another class (like tester)
Used scanner to slow down the game so
you can see what happens
 Visualized how you can translate a
location to a spot on a game board

