Key Implication in Java 1.4.2 sdk (Ready to Program)

[Artimes]

I am creating an asteroids type game with 2 players, got the phyics and the roation and movement yadadada... but it is kind of hard to play a game if you can't input and key values on the keyboard. I have tried the following, does not work all that...

code:

import java.applet.*; import java.awt.*; public class Testkeydown extends Applet {     // Place instance variables here     public boolean keyDown (Event evt, int inkey)     {         Graphics g = getGraphics ();         g.setColor (Color.white);         g.fillRect (1, 1, 200, 30);         g.setColor (Color.red);         g.drawString ("Key: " + (char) (inkey) + "      ASCII :" + Integer.toString (inkey), 40, 20);         return true;     }     public void init ()     {         resize (400, 400);         // Place the body of the initialization method here     } // init method     public void paint (Graphics g)     {         // Place the body of the drawing method here     } // paint method } // Teskeydown class

You can only have 1 key pressed at a time, and I need multiple keys. At least 2 per player (directional and momental).

I have been researching KeyListener but I can never get it to work in Read to Program (the crappy ass compliler my school uses... and this is a project for school).

I've been using the following, but no luck in 1.4.2 sdk......

code:

import java.applet.*; import java.awt.*; public class test extends Applet {     public void keyPressed (KeyEvent e)     {         switch (e.getKeyCode ())         {             case KeyEvent.VK_UP:                 break;             case KeyEvent.VK_DOWN:                 break;             case KeyEvent.VK_LEFT:                 break;             case KeyEvent.VK_RIGHT:                 break;             default:                 break;         }     }     public void keyReleased (KeyEvent e)     {     }     public void keyTyped (KeyEvent e)     {     } }

My program also must stay an applet, and I was looking but I am not sure what I should import at the top of the program. I know the methods keyPressed, Released, and Typed exist in 1.4.2 sdk and Ready to Program.

A little diretion would be greatly appreciated.

I whould look in to keylisteners. Witch looks kind of like what you are doing but with RTP that has some odditys to it.

Now how to get around only one keyinput at a time whould be to use keyPressed and keyReleased to check for both keys being down. So rather then using a case use if statmens like:

code:

if (e.getKeyCode() = KeyEvent.VK_UP)       do somthing if (e.getKeyCode() = KeyEvent.VK_LEFT)       do somthing eltes
