currentSlide number changes when perPage changes

[EricSSartorius]

I have noticed that the currentSlide index isn't always the exact index of the image in the carousel when using different numbers for perPage.
For example, using perPage: {0: 1, 600: 3, 1240: 5}, works visually but I will randomly get negative and inconsistent numbers for currentSlide depending on if the perPage number is at 1, 3, or 5.

Hi.

I see what is going on. It does lots of calculations to put a carousel in a correct location when you use loop: true. you are right that the index should be the one that user sees. I will try to change it in future versions.

Thanks for reporting Eric and have a cool day :)

I solved this problem for correct dots navigation using this code:

// carousel = siema instance
let currentSlide = carousel.currentSlide;
if (currentSlide < 0) {
  currentSlide = carousel.innerElements.length + currentSlide;
}
