Hi,

Woking on a game and have got the keypressed working just not the other two. Have looked at different ways of doing it on various sites, cant see what i am doing wrong. any hlep will be appreciated...

public void keyReleased(int keyCode)
{
repaint();
}

public void keyRepeated(int keyCode) //activates when the user repeats any button
{
try
{
eventType = "repeated";
this.keyCode = keyCode;
while(this.getGameAction(keyCode)== keyCode)
{
keyPressed(keyCode);
repaint();

}
}
catch(Exception e)
{
System.out.println("Sprite Control Class : keyRepeated :" + e);
}
}
public void keyPressed(int keyCode) // this function is activited when the user hits a button on the keypad
{
try
{
eventType = "pressed"; // set event type
this.keyCode = keyCode; // set keycode
if ( (50 == keyCode || 52 == keyCode || 54 == keyCode || 56 == keyCode) &&running == true)
{
PlayerShip1.moveShip(keyCode); // if the keycode is 50 or 52 or 54 or 56 and game is running
repaint(); // call the player ship class to update and repaint
}
if (53 == keyCode && running == true) // if the keycode is 53 and game is running
{
shipPositionX = PlayerShip1.getPositionX(); // set positions
shipPositionY = PlayerShip1.getPositionY();
int num1 = playerImage.getWidth(); // set width of image
PlayerShoot1.Shoot((num1 + shipPositionX), (shipPositionY+5), 0); // call player shoot to add shot at the positions and also the bullet type
repaint();
}
if (51 == keyCode && running == true)
{
shipPositionX = PlayerShip1.getPositionX();
shipPositionY = PlayerShip1.getPositionY(); // same as last but bullet type
int num1 = playerImage.getWidth(); // is 1 for missile
PlayerShoot1.Shoot(num1 + shipPositionX, shipPositionY, 1);
repaint();
}
}
catch(Exception e)
{
System.out.println("Sprite Control Class : keypressed :" + e);
}
}

Just testing it keyrepeated isnt being called at all in the program, keyreleased is though.

Your keyRepeated function is a mess.
First of all, don't do while's in event-handling functions, as they are called as a response to an event, and you are just blocking it.
Second,

while(this.getGameAction(keyCode)== keyCode)

is wrong. Don't expect getGameAction(keyCode) to be the same as keyCode.

My advise is that on keyRepeated, just call keyPressed with the suplied keyCode.

I have updated the code, keyRepeated is still not being called

public void keyReleased()
   {
      buttonPressed = false;
      repaint();
     
   }

   public void keyRepeated(int keyCode) //activates when the user repeats any button
   {

      try
      {
         buttonPressed = true;
         eventType = "repeated";
         this.keyCode = keyCode;

         if (hasRepeatEvents() && buttonPressed == true)
         {
            keyPressed(keyCode);
            repaint();
         }
      }
      catch(Exception e)
      {
         System.out.println("Sprite Control Class : keyRepeated :" + e);
      }
   }
   public void keyPressed(int keyCode)   // this function is activited when the user hits a button on the keypad
   {
      try
      {
         eventType = "pressed";              // set event type
         buttonPressed = true;
         this.keyCode = keyCode;             // set keycode
         if( (50 == keyCode || 52 == keyCode || 54 == keyCode || 56 == keyCode) &&running == true && buttonPressed == true)
         {
            PlayerShip1.moveShip(keyCode);             // if the keycode is 50 or 52 or 54 or 56 and game is running
            repaint();                                 // call the player ship class to update and repaint
         }
         if (53 == keyCode && running == true && buttonPressed == true)         // if the keycode is 53 and game is running
         {
            shipPositionX = PlayerShip1.getPositionX();     // set positions
            shipPositionY = PlayerShip1.getPositionY();
            int num1 = playerImage.getWidth();              // set width of image
            PlayerShoot1.Shoot((num1 + shipPositionX), (shipPositionY+5), 0);  // call player shoot to add shot at the positions and also the bullet type
            repaint();
         }
         if (51 == keyCode && running == true)
         {
            shipPositionX = PlayerShip1.getPositionX();
            shipPositionY = PlayerShip1.getPositionY();           // same as last but bullet type
            int num1 = playerImage.getWidth();                    // is 1 for missile
            PlayerShoot1.Shoot(num1 + shipPositionX, shipPositionY, 1);
            repaint();
         }
        else if(keyCode == 55)
         {
            keyReleased();
         }
      }
      catch(Exception e)
      {
         System.out.println("Sprite Control Class : keypressed :" + e);
      }
   }

since keyrepeated and keyreleased dont seem to be called im checking in the game loop if a button is pressed and calling the keyrepeated, it works as in the ship moves but doesnt stop moving when i stop pressing the button only stops when i push another button.

  if((50 == keyCode || 52 == keyCode || 54 == keyCode || 56 == keyCode) && keyCode != 53)
            {
               repeatKeys();
            }
            else if(???????)
            {
                  repaint();
            }

Not all devices call keyRepeated(). Use only keyPressed() and keyReleased().

Also, *never* perform any of your game logic in event handers like keyPressed() or paint(). Avoid calling repaint() (and *never* call serviceRepaints()!) from other event methods like keyPressed().

Create a single, separate Thread for game logic. Use your key methods only to record what keys are pressed. Then pick up this information in the game loop, process it, and call repaint()/serviceRepaints().
