football game can't be done in an _applet_ form.  The game has to simulate traffic (e.g. there are constraints on the motion of the _object_s and The idea is not only to avoid collisions, but also to adapt one motion to another.  I'm wondering if someone has created a basic football game or if someone can give me a site where to find some good information on this subject.   We are wanting the football game to be as close as possible to a real football game.  Where the user would be able to control the p_layer_ that has the football, but I think we are going to start out only being able to control the QB.  And before each play, the user will use radio buttons to choose a Run (left or right) play or Pass(left or right) play.   Thanks for any help you can give me!! Do you by any chance go to Full Sail? A friend of a friend of mine was in the game design and development program there, and he had a very similar project. If so, how do you like it? The guy I spoke to said it was really intense. EVT

Do you by any chance go to Full Sail? A friend of a friend of mine was in the game design and development program there, and he had a very similar project. If so, how do you like it? The guy I spoke to said it was really intense. EVT I go to mizzou, and I haven't yet taken any game design classes.  In a couple semesters though. Can anyone tell me why I can't move the QB?  I doesn't even enter the class KeyHandler public class MyPanel extends JPanel{                 KeyEvent evt;                 Toolkit tk1 = Toolkit.getDefaultToolkit();                 Image QBp_layer_ = tk1.getImage( QB.gif );                 private P_layer_[] offense;                 private P_layer_[] defense;                 public MyPanel(){                     KeyHandler listener = new KeyHandler();                      addKeyListener(listener);                 System.out.println( listener + listener);                 setBackground(Color.green);                     }   //displaying the football p_layer_ and transfering the info passed to offense  public void display (P_layer_[] footballp_layer_) {offense = footballp_layer_; repaint();}                 public void paintComponent (Graphics g) {                         super.paintComponent(g);                         paintP_layer_s(g,offense[0]);                     } //paintComponent //painting the p_layer_s image         public void paintP_layer_s(Graphics g,P_layer_ FBp_layer_){                 if(FBp_layer_ instanceof Q{                  g.drawImage(QBp_layer_,FBp_layer_.x,FBp_layer_.y,this);                 // System.out.println( drawimage );                                         }                                 } //TO MOVE THE QB          public class KeyHandler implements KeyListener{                     //To move the QB               System.out.println( Entered KeyHandler );                 public void keyPressed(KeyEvent evt){                    int x=1;                    int y=1;                    int ofx, ofy;                //offense[0] is the QB                    ofx = offense[0].getX();                    ofy = offense[0].getY();           if(evt.getKeyCode()==KeyEvent.VK_LEFT){ofx=ofx+x; offense[0].x=ofx;}         if(evt.getKeyCode()==KeyEvent.VK_RIGHT){ofx=ofx-x; offense[0].x=ofx;}         if(evt.getKeyCode()==KeyEvent.VK_UP){ofx=ofx-y; offense[0].y=ofy;}         if(evt.getKeyCode()==KeyEvent.VK_DOWN){ofx=ofx+y; offense[0].y=ofy;}                         }                         public void keyReleased(KeyEvent evt){}                         public void keyTyped(KeyEvent evt){}                           public boolean isFocusTraversable(){return true;}             }//KeyHandler             }//MyPanel Thanks for any help!

I got it to work, thanks

Thanks! that worked. sorry to keep asking questions! I have another question.  I have 2 panels one for the buttons,time, and score board.  And the other for the football field.  The screen keeps flickering really bad, to the point where I have to click on the buttons many times in order for them to work.  If I slow the time throgh the loop down, then I don't have that problem but I have to slow it down to 1 sec.  but I want it more around 200 milliseconds.   I've tried public void update(Graphics g){ paint(g); }   but that didn't help any.  Does anyone know a way I can update the panels w/out calling repaint(); all the time.  I've also tried panel1.repaint();  panel2.repaint();  And that doesn't work. Thanks for any help!!! Andy
