Our team is using sliders to determine the size of the map prior to editing. Our sliders give a range from 10 to 30 on both width and length. However, in certain circumstances, we want to have users to pick from at least 20 by 20. Right now, I have the size controller window to make a warning alert if the size was smaller than 20 by 20. But I want to make sliders to change so that from 20 to 30 is only given without making another fxml. Is there a way to make sliders look from 20 to 30 instead of original(10 to 30) without creating a new fxml when maze and random were selected?
