Who Cares

My Contributions

Hi,

/I am trying to implement random numbers in this game but I am pretty brain dead as to how to do that. I was able to implement random numbers on a rock paper scissors game. I started with a 2dArray approach to create a 3 X 3 layout on the applet. Now I just changed the size of the applet so the single D array can fit nicely.

//Right now I need to have the PC make a move on the game, then follow that move with a human user then the PC again and so on, until either one has won or 9 moves have been made on the board.

//How do I make the PC make a move? Thank you,

Hope that helps.

Well, this is where I am stucked! I make a move, then the PC makes a move, so far so good but after I make a second move the applet does not make another move. I double checked the loop and cannot see anything wrong, the way a read it, It should make a move after I do each time. I am clearly missing something and I just dont know what. If anyone steps in THXs in advance. CODE import java.util.; import java.util.Random; import javax.swing.; import java.awt.; import java.awt.event.; public class JTicTacToe extends JApplet implements ActionListener { JLabel someText = new JLabel(" Enter the number of expected guest for the event: "); JTextField firstNum = new JTextField(15); JLabel test_two = new JLabel(""); Container test = getContentPane(); Random rand = new java.util.Random(); String letter4User = "X"; String letterForPC = "O"; String[] dummyInput = {" ", " ", " ", " ", " ", " ", " ", " ", " "}; int [] verify = { 0, 1, 2, 3, 4, 5, 6, 7, 8}; JButton[] TicTac = new JButton[dummyInput.length]; int random = ((int) (Math.random() * 100) % 9 + 1); Font convertion = new Font ("Bookman Old Style", Font.ITALIC, 13); public void init() { test.setLayout(new FlowLayout()); firstNum.addActionListener(this); for(int y = 0; y < dummyInput.length; y++) { TicTac[y] = new JButton(dummyInput[y]); test.add(TicTac[y]); TicTac[y].addActionListener(this); } } public void actionPerformed(ActionEvent r) { Object source = r.getSource(); for(int b = 0; b < TicTac.length; b++) if(source == TicTac[b] ) { TicTac[b].setText(letter4User); TicTac[random].setText(letterForPC); } } }
