Question

用JAVA实现了控制小车的速度和方向，但是想把用KeyEvent控制变成鼠标点击button控制，有没有大神帮忙改下

import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.awt.geom.*;
import javax.swing.Timer;
import javax.swing.*;

class TestPanel extends JPanel
{
Timer myTimer;
int wait, wd, ht;
Robot robot;
double simtime = 0.0;
int x=210,y=210,velL=6,velR=6,stage=0;

TestPanel()
{
robot = new Robot(210,210,6,-6,Color.BLUE);
}

public class ShortTest2 extends JFrame implements ActionListener {
public void keyPressed(KeyEvent e){
int c=e.getKeyCode();

if (c==KeyEvent.VK_UP)
{
velR++;

}

if (c==KeyEvent.VK_DOWN)
{
velR--;
}

if (c==KeyEvent.VK_W)
{
velL++;
}

if (c==KeyEvent.VK_S)
{
velL--;
}
System.out.println("vR: "+ velR+"vL:"+velL);

}*/
public void keyTyped(KeyEvent e){}
public void keyReleased(KeyEvent e){}

public void update()
{
wd = getWidth();
ht = getHeight();
double tstep, tmore;
//tmore = 1.0;

robot.move(0.05);
simtime = simtime + 0.05;

//robot.setPose(x,y,0);
robot.setVelocity(velR,velL);
repaint();
}

public void paintComponent(Graphics g)
{
super.paintComponent(g);
robot.draw(g);

}
}

public void startAnimation()
{
if (myTimer == null)
{
myTimer = new Timer(20,new TimerHandler() );
myTimer.start();
}
else if (!myTimer.isRunning()) myTimer.restart();
}

public void stopAnimation()
{
myTimer.stop();
}

private class TimerHandler implements ActionListener

{

update();
}
}
}

public class motion extends JApplet

add(panel);
}

}
catch (Exception e) {
}
}

public void start() {
panel.startAnimation();
}

public void stop() {
panel.stopAnimation();
}

public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable() {
public void run()
{
TestPanel panel = new TestPanel();
JFrame frame = new JFrame("Robot Motion");
frame.add(panel);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(440,460);
frame.setVisible(true);
panel.startAnimation();
}
});
}

ShortTest2 m = new ShortTest2();
m.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
m.setSize(600, 370);
m.setLocationRelativeTo(null);
m.setVisible(true); }
}

机器人的设计再另一个程序里，字数太多，发不出来了，可私信
程序有误，最后多了些东西，大神有意向请私信！！

Answer 1

用几个JButton代替方向，然后给他们加监听，其他的就一样了

Answer 2

画几个JButton，然后用监听器触发Oncliked的方法，跟你按键控制差不多的原理

Answer 3

我感觉很容易修改.要改可以私信我
