Java Swing五子棋
项目地址：https://github.com/ListeningRift/gobang
之前用python的pygame这样一个专门用于游戏制作的游戏框架写了一个扫雷，这回事用Java Swing库这个用于创建GUI的库实现了一个五子棋，我持有的观点不变，在初学时写个益智类小游戏，对算法接触基本语法等各方面都有好处。
还是一样的没有把太多精力放在界面美化上，界面的美化我个人认为大体归功于哭的熟练程度，大部分时间花在API的熟悉上，所以并没有花太多精力。而且相对于一款完整的游戏，差的也比较远，我只做了主要游戏界面，开始界面，胜利界面都省略了。
贴个代码记录一哈：
首先是Game.java文件，主要做了一个JFrame窗体创建的工作，其次就是点击事件监听。
import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
public class Game extends JFrame implements MouseListener {
private static Insets insets;
private static GamePanel panel;
public static final int operationWidth = 80;
public static void main(String[] args) {
Game game = new Game();
game.start();
}
public Game() {
addMouseListener(this);
setSize(GamePanel.WIDTH + 14 + operationWidth, GamePanel.HEIGHT + 37);
setTitle("五子棋");
setBackground(new Color(209,190,130));
setResizable(false);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
insets = getInsets();
addButton();
}
public void start() {
panel = new GamePanel();
add(panel);
Thread th = new Thread((Runnable) panel);
th.start();
}
public void mouseClicked(MouseEvent e) {
int[] XY = getXY(e);
// TODO limit the range
if (XY[0] 19 ||
XY[1] 19) {
System.out.println("over");
return;
}
Piece newPiece = new Piece(getPlayer(), XY[0], XY[1]);
GamePanel.pieces.add(newPiece);
panel.repaint();
newPiece.judge();
}
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
public int[] getXY(MouseEvent e) {
int mouseX = e.getX();
int mouseY = e.getY() - insets.top;
int X = (int) Math.floor(mouseX / GamePanel.gridWidth);
int Y = (int) Math.floor(mouseY / GamePanel.gridHeight);
int restWidth = mouseX - X * GamePanel.gridWidth;
int restHeight = mouseY - Y * GamePanel.gridHeight;
if (restWidth < GamePanel.gridWidth / 2) {
X = X - 1;
}
if (restHeight < GamePanel.gridHeight / 2) {
Y = Y - 1;
}
return new int[]{X, Y};
}
public String getPlayer() {
return GamePanel.pieces.size() % 2 != 0 ? "white" : "black";
}
public void addButton() {
JButton back = new JButton("悔棋");
back.setBounds(GamePanel.WIDTH + 7, GamePanel.gridHeight + 30, 60, 30);
back.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent actionEvent) {
GamePanel.pieces.remove(GamePanel.pieces.size() - 1);
panel.repaint();
}
});
JButton giveUp = new JButton("认输");
giveUp.setBounds(GamePanel.WIDTH + 7, GamePanel.gridHeight + 90, 60, 30);
giveUp.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent actionEvent) {
GamePanel.win(getPlayer());
}
});
add(back);
add(giveUp);
}
}
第二部分就是游戏JPanel部分，主要负责游戏主界面绘制，以及游戏输赢动作（这个动作没有认真去写，只是在控制台输出一下胜方而已）。
import javax.swing.JPanel;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.BasicStroke;
import java.util.ArrayList;
public class GamePanel extends JPanel {
public static final int WIDTH = 672;
public static final int HEIGHT = 672;
public static int gridWidth;
public static int gridHeight;
public static ArrayList pieces = new ArrayList();
public GamePanel() {
setBackground(new Color(209,190,130));
setSize(WIDTH, HEIGHT);
gridWidth = getWidth() / 21;
gridHeight = getHeight() / 21;
}
@Override
public void paint(Graphics g) {
super.paint(g);
Graphics2D g2d = (Graphics2D) g;
g2d.setStroke(new BasicStroke(2));
for (int i = 1; i < 21; i++) {
g.drawLine(i * gridWidth, gridHeight, i * gridWidth, gridHeight * 20);
g.drawLine(gridWidth, i * gridHeight, gridWidth * 20, i * gridHeight);
}
for (Piece piece: pieces) {
piece.paint(g2d);
}
}
public static void win(String player) {
System.out.println(player);
}
}
第三部分写了一个棋子类，负责妻子绘制与判断连线数字判断。
import java.awt.*;
public class Piece {
private static final int r = 14;
public Color color;
public int x;
public int y;
public Piece(String color, int x, int y) {
if (color.equals("black")) {
this.color = Color.BLACK;
} else if (color.equals("white")) {
this.color = Color.WHITE;
}
this.x = x;
this.y = y;
}
public void paint(Graphics2D g) {
g.setColor(color);
g.fillArc((x + 1) * GamePanel.gridWidth - r, (y + 1) * GamePanel.gridHeight - r, 2 * r, 2 * r, 0, 360);
g.setColor(Color.BLACK);
g.setStroke(new BasicStroke(1));
g.drawArc((x + 1) * GamePanel.gridWidth - r, (y + 1) * GamePanel.gridHeight - r, 2 * r, 2 * r, 0, 360);
}
public void judge() {
String player = "";
if (color == Color.BLACK) {
player = "black";
} else if (color == Color.WHITE) {
player = "white";
}
if (judgeHorizontal() || judgeVertical() || judgeLeanToLeft() || judgeLeanToRight()) {
GamePanel.win(player);
}
}
public boolean judgeVertical() {
int number = 1;
for (int i = 1; i < 6; i++) {
if (getTop(i)) {
number++;
} else {
break;
}
}
for (int i = 1; i = 5;
}
public boolean judgeHorizontal() {
int number = 1;
for (int i = 1; i < 6; i++) {
if (getLeft(i)) {
number++;
} else {
break;
}
}
for (int i = 1; i = 5;
}
public boolean judgeLeanToLeft() {
int number = 1;
for (int i = 1; i < 6; i++) {
if (getTopLeft(i)) {
number++;
} else {
break;
}
}
for (int i = 1; i = 5;
}
public boolean judgeLeanToRight() {
int number = 1;
for (int i = 1; i < 6; i++) {
if (getTopRight(i)) {
number++;
} else {
break;
}
}
for (int i = 1; i = 5;
}
public boolean getTop(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x && y == p.y + distance) {
return p.color == color;
}
}
return false;
}
public boolean getBottom(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x && y == p.y - distance) {
return p.color == color;
}
}
return false;
}
public boolean getRight(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x - distance && y == p.y) {
return p.color == color;
}
}
return false;
}
public boolean getLeft(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x + distance && y == p.y) {
return p.color == color;
}
}
return false;
}
public boolean getTopRight(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x - distance && y == p.y + distance) {
return p.color == color;
}
}
return false;
}
public boolean getTopLeft(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x + distance && y == p.y + distance) {
return p.color == color;
}
}
return false;
}
public boolean getBottomRight(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x - distance && y == p.y - distance) {
return p.color == color;
}
}
return false;
}
public boolean getBottomLeft(int distance) {
for (Piece p: GamePanel.pieces) {
if (x == p.x + distance && y == p.y - distance) {
return p.color == color;
}
}
return false;
}
}
实现的东西比较少，只是大概的一个骨架，贴了全部代码，记录一下在这无聊的时间里的消遣玩具。
