How can I increase slideshow speed in a Narrative theme?

[Gasperpremoze]

Hi there.

In a Narrative theme, the slideshow loops in about 7 seconds rate, but I need it to loop in 1 second rate. How do we make it work? Thank you.

1. Click Online Store and then Themes. 
2. Next, click on the Actions drop-down.
3. From the drop-down, select Edit Code (as shown here). 
4. Find the Assets folder and then open up the custom.js file.
5. Once you open the custom.js file, you will just need to copy and paste the below code. Here is a quick screenshot to show you where to paste the code. 

var sections = window.theme.sections;
var slideshowAutoExtension = {
  init: function() {
    this.on('slideshow_desktop_init_done', this._autoplaySlideshow.bind(this));
  },
  _autoplaySlideshow: setInterval(function() {
    var $slide = $('.slideshow__slide--active')
                   .removeClass('slideshow__slide--active');

    var $button = $('.slideshow__button--active')
                   .removeClass('slideshow__button--active');

    var $slides = $('.slideshow__slide');

    var currentIndex = ($slides.index($slide) + 1) % $slides.length;

    $slides
      .eq(currentIndex)
      .addClass('slideshow__slide--active');

    var $buttons = $('.slideshow__button')
      .eq(currentIndex)
      .addClass('slideshow__button--active');

  }, 1000)

};

sections.extend('slideshow', slideshowAutoExtension);

Thank you dmwwebartisan it works perfectly.

Now there is another issue - the transition between slides. Every time it transit, it flashes a white screen and it feels annoying. Can it transit with a nice fade in 200 milliseconds, without a white screen between?

Thank you.

Please remove previous js script and add this script

var sections = window.theme.sections;
var slideshowAutoExtension = {
  init: function() {
    this.on('slideshow_desktop_init_done', this._autoplaySlideshow.bind(this));
  },
  _autoplaySlideshow: setInterval(function() {
    var $slide = $('.slideshow__slide--active')
                   .removeClass('slideshow__slide--active');

    var $button = $('.slideshow__button--active')
                   .removeClass('slideshow__button--active');

    var $slides = $('.slideshow__slide');

    var currentIndex = ($slides.index($slide) + 1) % $slides.length;

    $slides
      .eq(currentIndex)
      .addClass('slideshow__slide--active');

    var $buttons = $('.slideshow__button')
      .eq(currentIndex)
      .addClass('slideshow__button--active');

  }, 200)

};

sections.extend('slideshow', slideshowAutoExtension);

Sorry, i didn't explain the problem very well. The speed of the loop 1000 (1 second) is perfect. But between the transition of the slides, it flashes the white light. It goes like this:

1. SlideA - (1second)

2. Transition - it flashes white color for about 200 (0.2 seconds)

3. SlideB - (1second)

Step "2" is the problem because it flashes the white color between slides and it feels annoying.
