I am checking for key presses and then based on the keys pressed I am moving a square around the screen. I am setting booleans for the keys WASD. But , Whenever I try to keep the key down , it takes a while till it moves continuously (Just a half second stop after a single move.) Any way to get rid of that and make it be "smooth"? Code:

 up = false;
 down = false;
 left = false;
 right = false;
 reset = false;

 while(Keyboard.next()){
     if (Keyboard.getEventKeyState()) {
        if(Keyboard.isKeyDown(Keyboard.KEY_SPACE)){
             reset = false;
        } 
         if(Keyboard.isKeyDown(Keyboard.KEY_W)){
            up = true;
        } 
        if(Keyboard.isKeyDown(Keyboard.KEY_S)){
            down = true;
         }
         if(Keyboard.isKeyDown(Keyboard.KEY_A)){
            left = true;
        }
        if(Keyboard.isKeyDown(Keyboard.KEY_D)){
            right = true;
        }
     }
}
