renderOnlyVisible in combination with Perspective plugin doesnt work.

[tobidemski]

Description

You can not navigate through each slide anymore if you enable renderOnlyVisible with the Perspective plugin altogether.

Steps to check or reproduce

Use the following plugins:

let plugins = [
    new Pagination({ type: 'scroll' }),
    new Perspective({ rotate: -1, scale: 2, perspective: 600 }),
    new Arrow()];

and following Flicking options:

align="center"
circular={true}
renderOnlyVisible={true}
plugins={plugins}
defaultIndex={1}
panelsPerView={3}

CSS example I used:

.flicking-container {
  max-width: 600px;
}

.flicking-viewport {
  padding-bottom: 32px;
}

.panel {
  border-radius: 5px;
  box-sizing: border-box;
  display: flex;
  height: 200px;
  justify-content: flex-start;
  margin-bottom: 10px;
  margin-right: 10px;
  padding: 30px 20px;
  position: relative;
  width: 50%;
  background-color: #f2a65e;
  color: #fff;
}

.flicking-arrow-next,
.flicking-arrow-prev {
  cursor: pointer;
  height: 64px;
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
  width: 64px;
  z-index: 2;
}

.flicking-arrow-prev {
  left: 10px;
}

.flicking-arrow-next {
  right: 10px;
}

.flicking-arrow-next:after,
.flicking-arrow-next:before,
.flicking-arrow-prev:after,
.flicking-arrow-prev:before {
  background-color: #f2a65e;
  content: "";
  height: 6px;
  position: absolute;
  width: 24px;
}

.flicking-arrow-next:before {
  right: 22px;
  top: 50%;
  transform: rotate(45deg);
  transform-origin: 100% 50%;
}

.flicking-arrow-next:after {
  right: 22px;
  top: calc(50% - 4px);
  transform: rotate(-45deg);
  transform-origin: 100% 50%;
}

.flicking-arrow-prev:before {
  left: 22px;
  top: 50%;
  transform: rotate(-45deg);
  transform-origin: 0 50%;
}

.flicking-arrow-prev:after {
  left: 22px;
  top: calc(50% - 4px);
  transform: rotate(45deg);
  transform-origin: 0 50%;
}

tsx example:

import Flicking, { ViewportSlot } from "@egjs/react-flicking";
import "@egjs/react-flicking/dist/flicking.css";
import { Arrow, Pagination, Perspective } from "@egjs/flicking-plugins";
import "@egjs/flicking-plugins/dist/pagination.css";
import "./flickering.css";

export default function FlickingPage() {
  let number = 50;
  var items = Array.apply(null, Array(number));

  let plugins = [
    new Pagination({ type: 'scroll' }),
    new Perspective({ rotate: -1, scale: 2, perspective: 600 }),
    new Arrow()];

  return (
    <div>
      <h1>Flicking Test</h1>

      <div className={"flicking-container"}>
        <Flicking
          align="center"
          circular={true}
          renderOnlyVisible={true}
          plugins={plugins}
          defaultIndex={1}
          panelsPerView={3}
        >
          {items.map((n: any, index: number) => {
            return <div key={index} className={"panel"}>{index + 1}</div>;
          })}
          <ViewportSlot>
            <span className="flicking-arrow-prev"></span>
            <div className="flicking-pagination"></div>
            <span className="flicking-arrow-next"></span>
          </ViewportSlot>
        </Flicking>
      </div>
    </div>
  );
