    Exclamation 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
    {
      public static final int APPLICATION_WIDTH = 800; 
      public static final int APPLICATION_HEIGHT = 500;
     
      final int AW=APPLICATION_WIDTH;
      final int AH=APPLICATION_HEIGHT;
      final int WAIT=5;
      final int MV_AMT=5;
      final int JUMP_AMT=100;
      final int U_SIZE=30;
      int xMove,yMove;
     
      UFO u1,u2,u3;
     
     
      public void init()
      {
       u1=new UFO();
       u2=new UFO();
       u3=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
     
      public void run()
      { 
        RandomGenerator rg =new RandomGenerator();
        GRectangle u1Box, u2Box, u3Box, g1Box;
     
        int xMove1=1,xMove2=1,xMove3=1;
        int yMove1=1,yMove2=0,yMove3=1/4;
     
        boolean u1Done=false, u2Done=false, u3Done=false;
     
     
        GUN g1=new GUN();
        add(g1,300,480);
        xMove=yMove=0;
        addKeyListeners();
     
        waitForClick();
     
     
     
     
        while(true)
        {
     
          u1.move(xMove1,yMove1);
          u2.move(xMove2,yMove2);

          { xMove2 = -xMove2 ; } 
          if ((u3.getX( ) <= 0) || (u3.getX( ) + U_SIZE >= AW)) 
          { xMove3 = -xMove3 ; }
     
         //at bottom of window
          if (u1.getY( ) == 450) 
          { yMove1 = -yMove1 ; } 
          if (u2.getY( ) == 450) 
          { yMove2 = -yMove2 ; }

    It sounds pretty much like you need to finish most of the assignment. And a word to the wise, mentioning your deadlines actually decreases your chances of getting help because it makes you seem impatient. There are hundreds of posts here, each with an urgent user behind it, so is your time more valuable than theirs simply because you mismanaged a deadline?

    Anyway, if you want help, you'll have to be more specific- what have you tried? Where are you stuck? I don't see any code for the stuff you mentioned. Did you even attempt to start it?

    PS- Why are you adding your KeyListeners twice? And I can't even compile this, because what you've posted is incomplete. You'll have to provide us with an SSCCE if you want help.
