TankWar 单机（JAVA版）版本0.4~版本0.6 让坦克动起来

本文主要是介绍TankWar 单机（JAVA版）版本0.4~版本0.6 让坦克动起来，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

版本0.4的项目要求是让坦克动起来由于在版本0.6也是让坦克听从我们指挥等会再写

在这里主要是建立一个屏幕刷新线程使屏幕达到时时刷新的效果

代码如下：

public class updateThread extends Thread{@Overridepublic void run() {// TODO Auto-generated method stubwhile(true){//刷新屏幕repaint();try {//设置线程睡眠时间Thread.sleep(30);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}

然后通过实例化窗口的时候实例化这个线程并且让它开始执行即可

new updateThread().start();

版本0.5 修改一下就可以了

//窗口的高度public static final int SCREENHEIGHT=600;//窗口的宽度public static final int SCREENWIDTH=800;

版本0.6就是添加键盘事件了

首先自定义键盘时间KeyMonitor 继承KeyAdapter重写里面的

public void keyPressed(KeyEvent e) {// TODO Auto-generated method stubmyTank.keyPressed(e);}@Overridepublic void keyReleased(KeyEvent e) {// TODO Auto-generated method stubmyTank.keyReleased(e);}

由于是坦克的移动而且控制的是我方坦克所以要把我方坦克定义为全局变量

然后为屏幕添加键盘监听事件通过监视键盘来移动myTank

移动坦克时通过调用Tank里面的方法

public void keyPressed(KeyEvent e) {// TODO Auto-generated method stubswitch (e.getKeyCode()) {case KeyEvent.VK_UP:y-=speed;break;case KeyEvent.VK_DOWN:y+=speed;break;case KeyEvent.VK_LEFT:x-=speed;break;case KeyEvent.VK_RIGHT:x+=speed;break;default:break;}}

其中speed为按键一次移动的长度。

全部代码如下：

TankClient类

package tankWar;import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.KeyAdapter;
import java.awt.event.KeyEvent;import javax.swing.JFrame;
import javax.swing.JPanel;public class TankClient extends JFrame {//窗口的高度public static final int SCREENHEIGHT=600;//窗口的宽度public static final int SCREENWIDTH=800;public static Tank myTank;//创建一个窗口public TankClient(){setTitle("坦克大战");//窗口的大小setSize(SCREENWIDTH, SCREENHEIGHT);//设置窗口的显示位置在屏幕中央setLocationRelativeTo(null);//关闭窗口的事件管理setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//不允许窗口的大小改动setResizable(false);setVisible(true);//添加自定义的paneladd(new TankClientPanel());//实例化我的坦克myTank=new Tank(50, 50, 50, 50);//为窗口添加键盘事件addKeyListener(new KeyMonitor());//启动屏幕刷新线程new updateThread().start();}public static void main(String[] args) {//启动窗口new TankClient();}public class KeyMonitor  extends KeyAdapter{@Overridepublic void keyPressed(KeyEvent e) {// TODO Auto-generated method stubmyTank.keyPressed(e);}@Overridepublic void keyReleased(KeyEvent e) {// TODO Auto-generated method stubmyTank.keyReleased(e);}}//自定义Jpanelpublic class TankClientPanel extends JPanel{//重写patit方法@Overridepublic void paint(Graphics g) {//画我的坦克myTank.draw(g);}}//屏幕刷新线程public class updateThread extends Thread{@Overridepublic void run() {// TODO Auto-generated method stubwhile(true){//刷新屏幕repaint();try {//设置线程睡眠时间Thread.sleep(30);} catch (InterruptedException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}
}

Tank类

package tankWar;import java.awt.BasicStroke;
import java.awt.Color;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.event.KeyEvent;
import java.awt.geom.Ellipse2D;
import java.awt.geom.Line2D;public class Tank {//坦克x坐标private int x;//坦克y坐标private int y;//坦克的宽private int width;//坦克的高private int height;//坦克移动的速度private int speed=5;public Tank() {super();// TODO Auto-generated constructor stub}public Tank(int x, int y, int width, int height) {super();this.x = x;this.y = y;this.width = width;this.height = height;}public int getX() {return x;}public void setX(int x) {this.x = x;}public int getY() {return y;}public void setY(int y) {this.y = y;}public int getWidth() {return width;}public void setWidth(int width) {this.width = width;}public int getHeight() {return height;}public void setHeight(int height) {this.height = height;}public void draw(Graphics g){Graphics2D g2=(Graphics2D) g;//画一个圆Ellipse2D e2=new Ellipse2D.Double(x, y, width, height);//颜色为红色g2.setColor(Color.RED);//填充g2.fill(e2);//画一条线 通过坦克的坐标计算炮杆的坐标//默认坦克朝上Line2D l2=new Line2D.Double(x+width/2, y+height/2, x+width/2, y+height/2-40);g2.setColor(Color.BLACK);g2.setStroke(new BasicStroke(3)); g2.draw(l2);}//我方坦克的键盘按下事件public void keyPressed(KeyEvent e) {// TODO Auto-generated method stubswitch (e.getKeyCode()) {case KeyEvent.VK_UP:y-=speed;break;case KeyEvent.VK_DOWN:y+=speed;break;case KeyEvent.VK_LEFT:x-=speed;break;case KeyEvent.VK_RIGHT:x+=speed;break;default:break;}}//我方坦克的键盘松下事件public void keyReleased(KeyEvent e) {// TODO Auto-generated method stub}
}

运行结果：
