LWJGL关键事件状态不起作用

Question

LWJGL seems to be bugging out on me (or I am being a dunce again). I am using the following code:

if(Keyboard.getEventKey() == Keyboard.KEY_Q) {
    if (Keyboard.getEventKeyState()) {
        System.err.println("Pressed");
    }else {
        System.err.println("Released");
    }
}

When I press and release 'Q', it prints out neither "Pressed" nor "Released". Help?

EDIT: Problem solved. You first must poll the Keyboard buffer before using getEventKey(). Fixed code is:

while(Keyboard.next()) {
        if(Keyboard.getEventKey() == Keyboard.KEY_Q) {
            System.out.println("HI");
            if (Keyboard.getEventKeyState()) {
                System.out.println("Pressed");
            }else {
                System.out.println("Released");
            }
        }
    }

Answer 1

Per API:

public static int getEventKey()

Please note that the key code returned is NOT valid against the current keyboard layout . To get the actual character pressed call getEventCharacter

Returns: The key from the current event

Try changing your first if statement to use getEventCharacter menthod as:

   if(Keyboard.getEventCharacter() == Keyboard.KEY_Q) {

Answer 2

This is what I do in my programs... I make a boolean for the character and then run a method in the game loop to check it:

public static boolean keyboardA;

public static void refresh() {
keyboardA = Keyboard.isKeyDown(Keyboard.KEY_A);
}

public static void game_loop() {
refresh();
}

If you need me to explain more just comment :P Hope it helps
