我试图在此代码中实现井字游戏逻辑。我什么都不要。它只需要成为玩家对玩家，就必须展示获胜者并询问您是否要再次比赛。我已经尝试使这项工作一段时间了，但没有成功。
import javax.swing.*;
import java.awt.*;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
public class TicTacToe {
public static void main(String[] args) {
JFrame frame = new JFrame(" TicTacToe");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(290, 300);
Board board = new Board();
frame.add(board);
frame.setResizable(false);
frame.setVisible(true);
}
}
class Board extends JComponent {
private int w = 265, h = 265;
char player = 'X';
public Board() {
addMouseListener(new MouseAdapter() {
@Override
public void mousePressed(MouseEvent me) {
int x = me.getX();
int y = me.getY();
int sideWidth = w / 3;
int sideHeight = h / 3;
int a = x / sideWidth;
int b = y / sideHeight;
int xStart = sideWidth * a + 10;
int yStart = sideHeight * b + +sideHeight - 10;
Graphics g = getGraphics();
g.setFont(new Font("monospaced", Font.PLAIN, 110));
g.drawString(player + "", xStart, yStart);
if (player == 'X') {
player = 'O';
} else {
player = 'X';
}
if
}
});
}
public void paint(Graphics g) {
g.drawLine(90, 0, 90, 300);
g.drawLine(185, 0, 185, 300);
g.drawLine(0, 85, 300, 85);
g.drawLine(0, 175, 300, 175);
}
}
说谁赢了，问您是否想再玩一次。
答案 0 :(得分：0)
显然，您可以编写游戏逻辑，但是您可以通过几个循环轻松绘制棋盘。
我会尝试获取您单击的单元格索引并将播放器数据存储到矩阵中。这样，您可以在需要绘制时简单地调用值。这也增加了关于谁拥有哪个单元的验证层。
char[][] cells = new char[3][3];
@Override
void mousePressed(MouseEvent e) {
int tileWidth = (int) Math.floor(BOARD_WIDTH / cells.length);
int tileHeight = (int) Math.floor(BOARD_HEIGHT / cells[0].length);
int col = (int) Math.floor(e.getX() / tileWidth);
int row = (int) Math.floor(e.getY() / tileHeight);
setPlayer(row, col);
}
void setPlayer(int row, int col) {
if (col < cells.length && row < cells[0].length) {
if (cells[row][col] == 0) {
cells[row][col] = player;
player = player == 'X' ? 'O' : 'X';
repaint();
}
}
}
此外，您应该使用paintComponent(g)而不是paint(g)。
