MOUSE CURSORS, help ?

-----------------------------------

hey guys
i am trying to get an image where my mouse happens to be for a game. 
im thinking cross hairs, since its a simple shoot 'em up. 

i've already tried drawing a simple X by taking the mousepos and using it as t he X's origin points. the problem there is that its too laggy, the time taken to redraw gives the actual mouse enough time to move some place else

any suggestions ?

Are you double or triple buffering? Whats your FPS? Is there a delay in the program? are you Bottlenecking by having your code perform too many processes at one time?

mmkay , after all your suggestions, i tried to narrow down to what was causing the lag 

a few things 

a) delay at the end of the paint method, its set to a 1000 now, because the 'characters' need that time to respawn
b) since the background is an image, the drawn cursor doesn't even show up unless i don't draw the background.

since nothing can be done about the delay, i tried to make a separate paint method for the crossHair and run it in the graphids method , but that didnt really work,i dont even know if you can have 2 paint methods ( but it should be able to since i've used a double buffer before and thats a paint method ). maybe it has to do the way im putting it ? 

 

 public void crossHairs (Graphics g)
    {
        g.drawOval (mouseXPos - 25, mouseYPos - 25, 30, 30); // draws 'crosshair' - test stages 

    }




    public void paint (Graphics g)
    {

  [syntax=""]crossHairs ();/syntax]// ERROR HERE, NO APPLICABLE OVERLOAD[
        posGenerator (); // calls the method that generates positions 
        healthMeter (); // calls  the method that adjusts health meter status 

        if (drawZombies)
        {

            //  g.drawImage (BACKGROUND, 0, 0, appWidth, appHeight, this); // commented out temp. 
            g.drawImage (zombie1, randomPosx1, randomPosy1, iconLength, iconLength, this);   // draws zombie1 at a random pos
            g.drawImage (zombie2, randomPosx2, randomPosy2, iconLength, iconLength, this);   // draws zombie2 at a random pos


        }


        // main interface screen - bottom of screen where stats displayed 

        g.setColor (Color.red);

        g.drawString ("Zombies Killed", 725, 595); // panel on side that shows user # of zombies killed 
        g.drawImage (zombieDead, 765, 600, 65, 65, this);   // draws zombiesKilled image, shows a dead zombie w/ big X on it 
        g.setFont (messageFontsize20);
        g.drawString (zombiesKilledScore+ " x ", 730, 650); // counter that deals with score


//... rest of drawing code goes here .... 

//a delay at the end of the paint method is about here 

  } // paint method ends here 


im guessing the way i set up that method is wrong or something  ? any ideas of how to work around that ?

p.s i also have a buffer problem if any one has a solution : adding a double buffer disables my mouse functions ,WHY ?
