1. Picture It Very Basic Game Picture Pepper

2. Original Game import java.util.Scanner; public class Game { public static void main() { 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 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."); } 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; } }

3. 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; } }

4. 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."); }

5. 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; } }

6. Finish Board Picture 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; } }

7. 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; } }

8. 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; } }

9. 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."); }

10. 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; } }

11. 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; } }

12. 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

13. 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
