Java keyboard input [on hold]
- by dØd
I'm trying to implement a input system that can detect whether a certain key was held or was only pressed briefly.
So far I have this:
KEY_INTERACTION_TRESHOLD = 400ms
//inside a constructor
shouldMeasure = true;
@Override
public void keyPressed(KeyEvent e) {
if (shouldMeasure) {
startTime = System.currentTimeMillis();
shouldMeasure = false;
return;
}
System.out.println("Button is held down");
e.consume();
}
@Override
public void keyReleased(KeyEvent e) {
if (System.currentTimeMillis() - startTime < KEY_INTERACTION_TRESHOLD) {
System.out.println("Button was only pressed briefly");
}
startTime = 0;
shouldMeasure = true;
e.consume();
}
Now this works, but the problem is that there is this delay between when I press a key to hold and when the message 'Button is held down' gets displayed. I understand why this delay occurs (for example when you press and hold a letter there will be a similar delay between the first and the second letter printed out), but I would like to somehow avoid it. I'm using only the Java API.
