Thread: Beginner. Need Help finishing a simple Shoot em up game ASAP!!!!

I am trying to create a simple shoot em up on java and it is due by tomorrow 5/2.

I need help making the gun I have created, shoot up to 10 bullets using the space bar. Also, I need some kind of either bullet countdown bar or something to show the shooter the number of bullets that he has left to shoot out of 10.

So far I have created the Ufo's that bounce around the screen randomly and the gun that moves along the bottom using the arrow keys. When a Ufo huts the gun the game ends and goes to a blank screen.

Here is what I have so far:

//Shoot.java 
import acm.graphics.*;
import acm.program.*; 
import java.awt.event.*;
import java.awt.*;
import acm.util.*;
 
public class Shoot extends GraphicsProgram

  final int JUMP_AMT=100;
  final int U_SIZE=30;
  int xMove,yMove;
 
  UFO u1,u2,u3;

  {
   u1=new UFO();

   RandomGenerator rg= new RandomGenerator();
   int rand1= rg.nextInt(0,AW-50);
   int rand2= rg.nextInt(0,AW-75);
   int rand3= rg.nextInt(0,AW-100);
 
   add(u1,rand1,0);
   add(u2,rand2,0);
   add(u3,rand3,0);
 
   xMove=yMove=0;
   addKeyListeners();
  }//init
 
  public void keyPressed(KeyEvent e) 
  { 
    int key = e.getKeyCode( ); 
 
    if (key == KeyEvent.VK_RIGHT) 
    { xMove = MV_AMT ; } 
 
    else if (key == KeyEvent.VK_LEFT) 
    { xMove = -MV_AMT ; } 
  } //keyPressed

Thank you so much
