随着互联网的普及和移动设备的广泛应用，游戏开发逐渐成为了一个热门的行业。Java作为一种跨平台、性能优越的编程语言，在游戏开发领域也有着广泛的应用。今天，就为大家分享一些Java小游戏源码，帮助新手轻松入门游戏开发的世界。

一、Java小游戏源码简介

Java小游戏源码是指使用Java语言编写的，可以在Java虚拟机（JVM）上运行的简单游戏程序。这些源码通常包含了游戏的主体逻辑、界面设计、资源管理等部分，是新手学习和实践游戏开发的好素材。

二、Java小游戏源码类型

1.控制类游戏源码

这类游戏源码主要针对玩家的操作进行设计，如迷宫、跳跃、躲避等。例如，以下是一个简单的控制类游戏源码示例：

`java import javax.swing.; import java.awt.event.; import java.awt.*;

public class Game extends JFrame implements KeyListener { private int x, y; // 玩家坐标 private final int width = 400; private final int height = 400;

public Game() {
    setTitle("控制类游戏");
    setSize(width, height);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setResizable(false);
    setLocationRelativeTo(null);
    addKeyListener(this);
    x = width / 2;
    y = height / 2;
    setVisible(true);
}
@Override
public void paint(Graphics g) {
    super.paint(g);
    g.setColor(Color.BLACK);
    g.fillRect(0, 0, width, height);
    g.setColor(Color.RED);
    g.fillRect(x, y, 20, 20);
}
@Override
public void keyPressed(KeyEvent e) {
    int key = e.getKeyCode();
    if (key == KeyEvent.VK_LEFT) {
        x -= 10;
    } else if (key == KeyEvent.VK_RIGHT) {
        x += 10;
    } else if (key == KeyEvent.VK_UP) {
        y -= 10;
    } else if (key == KeyEvent.VK_DOWN) {
        y += 10;
    }
    repaint();
}
@Override
public void keyReleased(KeyEvent e) {}
@Override
public void keyTyped(KeyEvent e) {}

}

public class Main { public static void main(String[] args) { new Game(); } } `

2.战斗类游戏源码

战斗类游戏源码主要涉及角色、技能、地图等元素，如RPG、塔防等。以下是一个简单的战斗类游戏源码示例：

`java import javax.swing.; import java.awt.; import java.awt.event.*;

public class BattleGame extends JFrame implements ActionListener { private final int width = 800; private final int height = 600; private Timer timer; private int playerX, playerY; private int monsterX, monsterY;

public BattleGame() {
    setTitle("战斗类游戏");
    setSize(width, height);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setResizable(false);
    setLocationRelativeTo(null);
    setLayout(null);
    playerX = width / 2;
    playerY = height / 2;
    monsterX = width - 100;
    monsterY = height / 2;
    timer = new Timer(20, this);
    timer.start();
    addKeyListener(new KeyAdapter() {
        @Override
        public void keyPressed(KeyEvent e) {
            int key = e.getKeyCode();
            if (key == KeyEvent.VK_LEFT) {
                playerX -= 10;
            } else if (key == KeyEvent.VK_RIGHT) {
                playerX += 10;
            } else if (key == KeyEvent.VK_UP) {
                playerY -= 10;
            } else if (key == KeyEvent.VK_DOWN) {
                playerY += 10;
            }
        }
    });
    setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
    int dx = playerX - monsterX;
    int dy = playerY - monsterY;
    if (dx * dx + dy * dy < 100) {
        monsterX -= 10;
    }
    repaint();
}
@Override
public void paint(Graphics g) {
    super.paint(g);
    g.setColor(Color.BLACK);
    g.fillRect(0, 0, width, height);
    g.setColor(Color.BLUE);
    g.fillRect(playerX, playerY, 50, 50);
    g.setColor(Color.RED);
    g.fillRect(monsterX, monsterY, 50, 50);
}
public static void main(String[] args) {
    new BattleGame();
}

} `

3.益智类游戏源码

益智类游戏源码主要针对玩家的逻辑思维和反应能力进行设计，如拼图、数独等。以下是一个简单的益智类游戏源码示例：

`java import javax.swing.; import java.awt.; import java.awt.event.*;

public class PuzzleGame extends JFrame implements ActionListener { private final int width = 300; private final int height = 300; private final int size = 3; private final int squareSize = width / size; private int[][] board; private Timer timer; private boolean isDragging = false; private int dragFromRow, dragFromCol, dragToRow, dragToCol;

public PuzzleGame() {
    setTitle("益智类游戏");
    setSize(width, height);
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    setResizable(false);
    setLocationRelativeTo(null);
    setLayout(null);
    board = new int[size][size];
    initializeBoard();
    timer = new Timer(20, this);
    timer.start();
    addMouseListener(new MouseAdapter() {
        @Override
        public void mouseClicked(MouseEvent e) {
            int row = e.getY() / squareSize;
            int col = e.getX() / squareSize;
            if (row >= 0 && row < size && col >= 0 && col < size) {
                if (board[row][col] == 0) {
                    isDragging = true;
                    dragFromRow = row;
                    dragFromCol = col;
                }
            }
        }
        @Override
        public void mouseReleased(MouseEvent e) {
            int row = e.getY() / squareSize;
            int col = e.getX() / squareSize;
            if (isDragging && Math.abs(row - dragFromRow) == 1 && Math.abs(col - dragFromCol) == 0) {
                swap(board, row, col, dragFromRow, dragFromCol);
                isDragging = false;
            }
        }
    });
    setVisible(true);
}
private void initializeBoard() {
    for (int i = 0; i < size; i++) {
        for (int j = 0; j < size; j++) {
            board[i][j] = (i + j) % size;
        }
    }
    board[size - 1][size - 1] = 0;
}
private void swap(int[][] board, int row1, int col1, int row2, int col2) {
    int temp = board[row1][col1];
    board[row1][col1] = board[row2][col2];
    board[row2][col2] = temp;
}
@Override
public void actionPerformed(ActionEvent e) {
    repaint();
}
@Override
public void paint(Graphics g) {
    super.paint(g);
    g.setColor(Color.BLACK);
    g.fillRect(0, 0, width, height);
    for (int i = 0; i < size; i++) {
        for (int j = 0; j < size; j++) {
            g.setColor(Color.BLUE);
            g.fillRect(j * squareSize, i * squareSize, squareSize, squareSize);
            g.setColor(Color.WHITE);
            g.drawString(String.valueOf(board[i][j]), j * squareSize + squareSize / 2, i * squareSize + squareSize / 2);
        }
    }
}
public static void main(String[] args) {
    new PuzzleGame();
}

} `
