本文介绍了二战期间美国使用的重型坦克,以及如何使用Java编写一个简单的坦克战斗游戏。
美国在二战期间设计了多款重型坦克,其中最著名的是M26 Pershing和M4A3E2 Jumbo Sherman。M26 Pershing是美国陆军装备的重型坦克之一,其主炮为90mm口径。M4A3E2 Jumbo Sherman则是Sherman坦克的改进版,其装甲可达到最厚的177mm。
在本节中,我们将使用Java编写一个简单的坦克战斗游戏。我们将使用Java图形库Swing和AWT。
游戏界面由以下元素组成:
import javax.swing.*;
import java.awt.*;
public class TankGame extends JFrame {
private static final int WIDTH = 800;
private static final int HEIGHT = 600;
private Tank playerTank;
private Tank enemyTank;
private Terrain terrain;
public TankGame() {
setTitle("Tank Game");
setSize(WIDTH, HEIGHT);
terrain = new Terrain();
playerTank = new Tank(200, 200);
enemyTank = new Tank(500, 500);
getContentPane().add(terrain);
getContentPane().add(playerTank);
getContentPane().add(enemyTank);
setVisible(true);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
}
import javax.swing.*;
import java.awt.*;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
public class Tank extends JComponent implements KeyListener {
private static final int WIDTH = 40;
private static final int HEIGHT = 40;
private int x;
private int y;
private boolean isPressedUp = false;
private boolean isPressedDown = false;
private boolean isPressedLeft = false;
private boolean isPressedRight = false;
public Tank(int x, int y) {
this.x = x;
this.y = y;
setSize(WIDTH, HEIGHT);
setOpaque(false);
}
@Override
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.setColor(Color.GREEN);
g.fillRect(0, 0, WIDTH, HEIGHT);
}
public void move() {
if (isPressedUp) {
y -= 5;
}
if (isPressedDown) {
y += 5;
}
if (isPressedLeft) {
x -= 5;
}
if (isPressedRight) {
x += 5;
}
repaint();
}
@Override
public void keyTyped(KeyEvent e) {
}
@Override
public void keyPressed(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_UP || e.getKeyCode() == KeyEvent.VK_W) {
isPressedUp = true;
}
if (e.getKeyCode() == KeyEvent.VK_DOWN || e.getKeyCode() == KeyEvent.VK_S) {
isPressedDown = true;
}
if (e.getKeyCode() == KeyEvent.VK_LEFT || e.getKeyCode() == KeyEvent.VK_A) {
isPressedLeft = true;
}
if (e.getKeyCode() == KeyEvent.VK_RIGHT || e.getKeyCode() == KeyEvent.VK_D) {
isPressedRight = true;
}
}
@Override
public void keyReleased(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_UP || e.getKeyCode() == KeyEvent.VK_W) {
isPressedUp = false;
}
if (e.getKeyCode() == KeyEvent.VK_DOWN || e.getKeyCode() == KeyEvent.VK_S) {
isPressedDown = false;
}
if (e.getKeyCode() == KeyEvent.VK_LEFT || e.getKeyCode() == KeyEvent.VK_A) {
isPressedLeft = false;
}
if (e.getKeyCode() == KeyEvent.VK_RIGHT || e.getKeyCode() == KeyEvent.VK_D) {
isPressedRight = false;
}
}
}
import javax.swing.*;
import java.awt.*;
public class GameControlPanel extends JPanel {
private JButton upButton;
private JButton downButton;
private JButton leftButton;
private JButton rightButton;
private JButton shootButton;
public GameControlPanel() {
setOpaque(false);
setLayout(null);
upButton = new JButton("Up");
downButton = new JButton("Down");
leftButton = new JButton("Left");
rightButton = new JButton("Right");
shootButton = new JButton("Shoot");
upButton.setBounds(350, 10, 100, 30);
downButton.setBounds(350, 70, 100, 30);
leftButton.setBounds(290, 40, 100, 30);
rightButton.setBounds(410, 40, 100, 30);
shootButton.setBounds(350, 210, 100, 30);
add(upButton);
add(downButton);
add(leftButton);
add(rightButton);
add(shootButton);
upButton.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
// Move player tank up
}
});
downButton.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
// Move player tank down
}
});
leftButton.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
// Move player tank left
}
});
rightButton.addKeyListener(new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
// Move player tank right
}
});
shootButton.addActionListener(e -> {
// Shoot
});
}
}
完成上述步骤后,即可运行坦克战斗游戏,玩家可以通过控制按钮移动坦克并射击来摧毁敌方坦克。
