Usage.tsx

"use client";

import * as React from "react";
import Component, { type Props, type State } from "@/components/ui/selection-context-menu";

const settings = { title: "A little less, but better." };
export const loopDuration = 6;

const ease = (x: number) => {
  const n = Math.max(0, Math.min(1, x));
  return n * n * (3 - 2 * n);
};

const pulse = (t: number, start: number, end: number) =>
  ease((t - start) / 0.3) * (1 - ease((t - end) / 0.3));

// Pure timeline: export frame n by passing n / 60. No timers or network calls.
export function showcase(time: number): State {
  const t = ((time % loopDuration) + loopDuration) % loopDuration;
  const r = pulse(t, 0.6, 3.4);
  return {
    open: r > 0,
    reveal: r,
    active: 1,
    selected: "Good design makes room for what matters.",
    highlighted: t > 3.4 && t < 4.8,
    notice: t > 3.4 && t < 4.8 ? "Passage highlighted locally." : "",
  };
}

export default function Demo(props: any = {}) {
  const { showcaseTime, ...incoming } = props;
  const merged = { ...settings, ...incoming };
  return (
    <div className="w-full min-h-[460px] flex items-center justify-center p-4 sm:p-6 bg-background">
      <Component
        {...merged}
        state={showcaseTime === undefined ? incoming.state : showcase(showcaseTime)}
        seeking={showcaseTime !== undefined || incoming.seeking}
      />
    </div>
  );
