按住LWJGL中的一个键

Question

I am using LWJGL and I want to cause an event to rapidly take place when I press and hold a key (like holding a letter key in word).

This is my attempt:

while(Keyboard.next())
{
    if (Keyboard.getEventKeyState())
    {
        if (Keyboard.isKeyDown(Keyboard.KEY_UP)) 
        {
            i += 5.0f;
        }
        if (Keyboard.isKeyDown(Keyboard.KEY_RIGHT)) 
        {
            i -= 1.0f;
        }
    }
}

Answer 1

if (Keyboard.getEventKeyState()) only runs when a key is pressed.

For holding down, use a boolean/integer to record whether your game loop should increase or decrease i .

Answer 2

I answered my own question by using a robot and a thread when pressed:

        if (Keyboard.isKeyDown(Keyboard.KEY_DOWN))
        {
            Robot robot = new Robot();
            robot.keyPress(KeyEvent.VK_DOWN);
            zpos -= 0.1f;
            Thread.sleep(100);
            robot.keyRelease(KeyEvent.VK_DOWN);
        }
