Looking at the javadoc I don't see a way to see if there is a keypress without explicitly checking a keycode. I'm not using buffered mode. What I would like to do is something like...

Keyboard.isKeyDown(KEY_ANYKEY);

is this possible and I'm just missing something. If it isn't possible any chance it will become possible?

thanks.

}

uhm yourself.

That only returns true if 'A' is pressed. I want an option that returns true if any key is pressed, false if no keys are pressed.

Just do:

boolean keyPressed = false;
for (int i = 0; i < 255; i ++) {
if (Keyboard.isKeyDown(i)) {
keyPressed = true;
break;
}
}


That's all you need to do. Nothing clunky about it at all either. We don't need to do it in LWJGL, because it's beyond our remit.

You could also switch from polling to buffered keyboard input.

Keyboard.create();
Keyboard.enableBuffer();

...

Keyboard.read();
while (Keyboard.next()) {
  if (Keyboard.state) {
    // A key has been pressed    
    // Don't break out of while loop, we need to eat
    // all the keyboard events to empty the buffer.
  }
}

In my current implementation it is better for me to drop some keys over taking the time to check all of them. I originally had it buffered, but a single key press would add too many instances of a keypress. I found that just polling and checking for the key allowed me to drop extraneous key presses without the user noticing.
