How to customize ProgressBar change?

Question

Java

The brain has gone beyond the mind.

I have a ProgressBar with a starting maximum value, for example ProgressBar.setMax(20), the value of the level (int lvl) and points (int exp).

When a new level is reached, say 2, I set ProgressBar.setMax(50).
The progress bar should reset to 0 and the score should start from the minimum value, from the leftmost position. Points must not be reset. For me, the scale simply increases by +30 and the reference point becomes somewhere around 1/3.

How can this be fixed?

Answer 1

ProgressBar.setMin(20)
