各位大神，小弟有个关于Java游戏设计方面的基础问题想要请教10

各位大神好，小弟尝试着写了一个平板弹球的代码，但在控制平板移动方面出现了问题，在按下相应的按键后平板没有移动。希望得到各位的指点，同时也希望各位能告诉我游戏AI设计的大致思路。以下是代码。
import java.awt.*;
import java.awt.event.*;
import javax.swing.Timer;
import java.util.*;
import java.util.List;
public class MultiBall extends Frame implements Runnable,ActionListener,KeyListener{
int d=30;
int x=-1;
int y=-1;
int x2=100;
int dx;
int dy;
int dx2=10;
int Width=300;
int Height=300;
Timer timer;
static List<MultiBall> list=new ArrayList<MultiBall>();
void draw(Graphics g){
g.fillOval(this.x, this.y, this.d, this.d);
move();
}
void draw2(Graphics g){
g.fillRect(this.x2, 100, 50, 20);
}
void move(){
x=x+dx;
y=y+dy;
if(x>(Width-d)|x<-1)
dx=-dx;
if(y>(Width-d)|y<-1)
dy=-dy;
}
MultiBall(int dx,int dy){
this.dx=dx;
this.dy=dy;
}
void lunchWindow(){
this.setBounds(300,300,this.Width,this.Height);
this.setBackground(Color.yellow);
this.setVisible(true);
}
public void paint(Graphics g){
draw2(g);
for(int i=0;i<list.size();i++){
list.get(i).draw(g);
}

}
public void actionPerformed(ActionEvent e){
repaint();
}
public void keyPressed(KeyEvent e){
while(true){
if(e.getKeyCode()==KeyEvent.VK_KP_LEFT)
this.x2=x2-dx2;
if(e.getKeyCode()==KeyEvent.VK_KP_RIGHT)
this.x2=x2+dx2;
}

}
public void keyReleased(KeyEvent e){

}
public void keyTyped(KeyEvent e){

}
public void run(){
timer=new Timer(20,this);
timer.start();
}
public static void main(String arg[]){
MultiBall mbo=new MultiBall(3,2);
mbo.lunchWindow();
Thread thread=new Thread(mbo);
mbo.list.add(new MultiBall(4,3));
mbo.list.add(new MultiBall(3,2));
mbo.list.add(new MultiBall(5,6));
thread.start();

}
}

构造方法里面添加this.addKeyListener(this);
public void keyPressed(KeyEvent e){
while(true){
if(e.getKeyCode()==KeyEvent.VK_KP_LEFT)
this.x2=x2-dx2;
if(e.getKeyCode()==KeyEvent.VK_KP_RIGHT)
this.x2=x2+dx2;
} }改成
public void keyPressed(KeyEvent e){
if(e.getKeyCode()==KeyEvent.VK_LEFT)
this.x2=x2-dx2;
if(e.getKeyCode()==KeyEvent.VK_RIGHT)
this.x2=x2+dx2;
}
