How to implement progressbar in Unity?

Question

C++ / C#

Hello everyone, we need to implement ProgressBar. There are 2 values:
expereince( double)
targetExpereince( double) The
maximum size of the rectangular strip 300px, the values ​​of expereinceand targetExpereincevary, but expereincewill never be greater than targetExpereince. If you imagine:
expereince = 1053.565443
targetExpereince = 2565.7323672
How can this be implemented? Ideally a separate method with 3 parameters:
expereince
targetExpereince
maxValue- Maximum strip length

Answer 1

x watermelons - 10%
300 watermelons - 100%
x = 10 * 300 / 100
do you mean that?
