tryin to write Connect Four
Having some problems with my code (alot actually but heres just a little bit). Everytime I call a method from the Board class (board.gameOver() etc.) it complains and I'm not sure why. It says the method is undefind
import java.applet.*;
import java.awt.*;
import java.util.*;
publicclass GameDisplayextends Appletimplements MouseListener
{
Board board;
String turn,message;
publicvoid init()
{
board =new Board();
turn ="red";
message ="";
addMouseListener(this);
}
publicvoid mouseClicked (MouseEvent me)
{
Location loc =new Location(me.getX(),me.getY());
if(loc.isValid(board) && board.isEmpty(loc))
{
if(turn.equals("red"))
{
board.add(new Piece(turn,loc.row(),loc.col()));
update();
}
elseif(turn.equals("blue"))
{
board.add(new Piece(turn,me.row(),me.col()));
update();
}
}
if(!(board.gameOver().equals("nobody")))
{
message ="Game Over! The winner is " + board.gameOver();
update();
}
}
publicvoid mouseEntered (MouseEvent me){}
publicvoid mousePressed (MouseEvent me){}
publicvoid mouseReleased (MouseEvent me){}
publicvoid mouseExited (MouseEvent me){}
publicvoid update()
{
paint(g);
}
publicvoid paint(Graphics g)
{
for(int i=0;i<board.getPieces().size();i++)
{
Piece p = board.getPieces().get(i);
g.drawImage(p.display(), p.getXloc(), p.getYloc(),null);//getX and getY have to return where to draw the thing. which means in Piece I have to figure out where they go
}
g.drawImage(board.display(), 0, 0,null);
if(!(board.gameOver().equals("nobody")))
{
g.drawString(message,0,0);
//Wait a certain amount of time
init();//Reset game
}
}
