Using it in a game


public void init(){
    new InputListener(this);
}

public void update(){
    if (Keyboard.isPressed(KeyEvent.VK_SPACE)){
        // Space is pressed
    }
    // Initial press of A
    Keyboard.setDetectionType(KeyEvent.VK_A, Action.Behaviour.INITIAL_DETECT);
    if (KeyBoard.isPressed(KeyEvent.VK_A){
        // A is pressed for the first time.
    }
    // Mouse click
    if (Mouse.isClicked()){
        // A mouse click happened.
    }
    // Mouse press
    if (Mouse.isPressed(Mouse.MOUSE_BUTTON_1)){
        // The left mouse button is pressed
    }
}
