wKgaoWcy1ZqAczN2AAUdifcOBoY436.png   正在阅读互联网寻觅灵感时,我发明了一个看起去很风趣的组件:

https://reactive.network/hackathon

我感觉带有运转 ASCII 艺术的区块看起去很酷,但我没有太大白它是若何完成的,因而我开端检查源代码。

我找到了看起去能够完成那项任务的代码,但它被粗简化了。

const { floor: ra, abs: KE, min: QE } = Math,    O5 = ["reactive.network REACTIVE.NETWORK", "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/|()1{}[]?-_+~<>i!lI;:,^`'. .:â–‘â–’â–“â–ˆ"],    G7 = Date.now() % 3 ? O5[1] : O5[0],    V5 = G7.length,    JE = { fps: 60 };function eT(e, t, n, r) {    const i = t.time * 8e-5,        s = QE(t.cols, t.rows),        o = t.metrics.aspect * 0.2,        l = { x: ((4 * (e.x - t.cols / 6.25)) / s) * o, y: (5 * (e.y - t.rows / 4)) / s },        u = ra(KE(YE(l) - i) * V5 + (ra(e.x / 1) % 2) * 2) % V5;    return G7[u];}const tT = () => {    const e = j.useRef(null),        [t, n] = j.useState({ height: null, width: null });    return (        j.useEffect(() => {            function r() {                n({ height: window.innerHeight, width: window.innerWidth });            }            if (typeof window < "u") return n({ height: window.innerHeight, width: window.innerWidth }), window.addEventListener("resize", r), () => window.removeEventListener("resize", r);        }, []),        j.useEffect(() => {            const r = e.current;            if (!r) return;            const i = 12,                s = ra(t.width / i) * 1.6,                o = ra(t.height / i),                l = { aspect: s / o },                u = setInterval(() => {                    let c = "";                    for (let d = 0; d < o; d++) {                        for (let f = 0; f < s; f++) c += eT({ x: f, y: d }, { cols: s, rows: o, metrics: l, time: Date.now() });                        c += ``;                    }                    r.textContent = c;                }, 1e3 / JE.fps);            return () => clearInterval(u);        }, [t]),        a.jsx("div", { style: { position: "absolute", top: 0, left: 0, width: "100%", height: "100%" }, children: a.jsx("div", { ref: e, style: { width: "100%", height: "100%", whiteSpace: "pre", overflow: "hidden" } }) })    );};function nT(e) {    return Math.cos(e.x * e.x - e.y * e.y);}const { floor: ia, abs: rT, min: iT } = Math,    D5 = ["reactive.network REACTIVE.NETWORK", "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/|()1{}[]?-_+~<>i!lI;:,^`'. .:â–‘â–’â–“â–ˆ"],    X7 = Date.now() % 3 ? D5[1] : D5[0],    F5 = X7.length,    sT = { fps: 60 };function oT(e, t, n, r) {    const i = t.time * 8e-5,        s = iT(t.cols, t.rows),        o = t.metrics.aspect * 0.2,        l = { x: ((4 * (e.x - t.cols / 6.25)) / s) * o, y: (5 * (e.y - t.rows / 4)) / s },        u = ia(rT(nT(l) - i) * F5 + (ia(e.x / 1) % 2) * 2) % F5;    return X7[u];}const aT = () => {    const e = j.useRef(null),        [t, n] = j.useState({ height: null, width: null });    return (        j.useEffect(() => {            function r() {                n({ height: window.innerHeight, width: window.innerWidth });            }            if (typeof window < "u") return n({ height: window.innerHeight, width: window.innerWidth }), window.addEventListener("resize", r), () => window.removeEventListener("resize", r);        }, []),        j.useEffect(() => {            const r = e.current;            if (!r) return;            const i = 12,                s = ia(t.width / i) * 1.6,                o = ia(t.height / i),                l = { aspect: s / o },                u = setInterval(() => {                    let c = "";                    for (let d = 0; d < o; d++) {                        for (let f = 0; f < s; f++) c += oT({ x: f, y: d }, { cols: s, rows: o, metrics: l, time: Date.now() });                        c += ``;                    }                    r.textContent = c;                }, 1e3 / sT.fps);            return () => clearInterval(u);        }, [t]),        a.jsx("div", { style: { position: "absolute", top: 0, left: 0, width: "100%", height: "100%" }, children: a.jsx("div", { ref: e, style: { width: "100%", height: "100%", whiteSpace: "pre", overflow: "hidden" } }) })    );},
凡是状况下,我会经过浏览最小化的代码去了解实在现(或许查找 .map 文件去复原本初代码)。不外,我认识到我从何尝试过让 ChatGPT 帮我做那件事...... 因而,我复造了上述一切代码,并请求 ChatGPT “注释代码”。以下是答复:

供给的代码十分庞大,但我会将其分化为更容易于了解的格局,注释其分歧局部及其功用。
概述该代码运用 JavaScript 界说了几个函数战组件,特殊是正在 React 使用顺序的高低文中。它处置运用预界说字符集合的字符死成一些静态文本内容,能够是 ASCII 艺术或某种视觉结果。另外,它借包罗用于事情处置、功能计时战 HTML 内容转换的适用函数。
要害部件战功用字符散挑选:
const { floor: ra, abs: KE, min: QE } = Math;const O5 = ["reactive.network REACTIVE.NETWORK", "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/|()1{}[]?-_+~<>i!lI;:,^`'. .:â–‘â–’â–“â–ˆ"];const G7 = Date.now() % 3 ? O5[1] : O5[0];const V5 = G7.length;这部分代码导入了一些常见的数学函数(floor、、abs和min),并定义了两组字符,存储在中O5。
根据当前时间(Date.now() % 3),它会选择其中一个集合(G7)以供稍后使用。
所选字符集的长度存储在中V5。
动态角色选择功能:
function eT(e, t, n, r) {    const i = t.time * 8e-5;    const s = QE(t.cols, t.rows);    const o = t.metrics.aspect * 0.2;    const l = { x: ((4 * (e.x - t.cols / 6.25)) / s) * o, y: (5 * (e.y - t.rows / 4)) / s };    const u = ra(KE(YE(l) - i) * V5 + (ra(e.x / 1) % 2) * 2) % V5;    return G7[u];}该eT函数根据输入位置(e.x,e.y)和当前时间(t.time)生成一个字符。
它使用一些纵横比计算来调整位置,并根据G7位置和时间的组合选择一个字符。
YE从代码中无法直接看出该函数的用途,但它似乎是此计算中使用的自定义函数。
tT用于显示动态内容的React 组件( ):
const tT = () => {    const e = j.useRef(null);    const [t, n] = j.useState({ height: null, width: null });    j.useEffect(() => {        function r() {            n({ height: window.innerHeight, width: window.innerWidth });        }        if (typeof window < "u") {            n({ height: window.innerHeight, width: window.innerWidth });            window.addEventListener("resize", r);            return () => window.removeEventListener("resize", r);        }    }, []);
    j.useEffect(() => {        const r = e.current;        if (!r) return;        const i = 12;        const s = ra(t.width / i) * 1.6;        const o = ra(t.height / i);        const l = { aspect: s / o };        const u = setInterval(() => {            let c = "";            for (let d = 0; d < o; d++) {                for (let f = 0; f < s; f++) c += eT({ x: f, y: d }, { cols: s, rows: o, metrics: l, time: Date.now() });                c += ``;            }            r.textContent = c;        }, 1e3 / JE.fps);        return () => clearInterval(u);    }, [t]);
    return a.jsx("div", { style: { position: "absolute", top: 0, left: 0, width: "100%", height: "100%" }, children: a.jsx("div", { ref: e, style: { width: "100%", height: "100%", whiteSpace: "pre", overflow: "hidden" } }) });};那是一个 React 组件,它设置一个距离,以运用静态死成的字符活期更新div元素的内容( )。e.current
它依据窗心巨细计较列数(s)战止数( ),然后用函数死成的字符挖充。odiveT
该结果以每秒指定的帧数运转(JE.fps)。
我持续讯问“用 TypeScript 完成等效代码并使其易于浏览”,并失掉了以下回答:

import React, { useEffect, useRef, useState } from 'react';
const selectedCharacterSet =  "$@B%8&WM#*oahkbdpqwmZO0QLCJUYXzcvunxrjft/|()1{}[]?-_+~<>i!lI;:,^`'. .:â–‘â–’â–“â–ˆ";const characterSetLength = selectedCharacterSet.length;
const calculateCharacter = (  x: number,  y: number,  cols: number,  rows: number,  aspect: number,  time: number,): string => {  const timeFactor = time * 0.000_08;  const size = Math.min(cols, rows);  const aspectRatio = aspect * 0.2;  const position = {    x: ((4 * (x - cols / 6.25)) / size) * aspectRatio,    y: (5 * (y - rows / 4)) / size,  };
  const index =    Math.floor(      Math.abs(        Math.cos(position.x * position.x - position.y * position.y) -          timeFactor,      ) *        characterSetLength +        (Math.floor(x) % 2) * 2,    ) % characterSetLength;  return selectedCharacterSet[index];};
type Size = {  height: null | number;  width: null | number;};
const AsciiArtGenerator: React.FC = () => {  const textRef = useRef(null);  const [size, setSize] = useState({ height: null, width: null });
  useEffect(() => {    const handleResize = () => {      setSize({ height: window.innerHeight, width: window.innerWidth });    };
    // Initial size setting    handleResize();
    window.addEventListener('resize', handleResize);    return () => {      window.removeEventListener('resize', handleResize);    };  }, []);
  useEffect(() => {    const element = textRef.current;    if (!element || !size.width || !size.height) return undefined;
    const cols = Math.floor(size.width / 12) * 1.6;    const rows = Math.floor(size.height / 12);    const aspectRatio = cols / rows;
    const intervalId = setInterval(() => {      let content = '';
      for (let y = 0; y < rows; y++) {        for (let x = 0; x < cols; x++) {          content += calculateCharacter(            x,            y,            cols,            rows,            aspectRatio,            Date.now(),          );        }
        content += 'n';      }
      element.textContent = content;    }, 1_000 / 60); // 60 fps
    return () => {      clearInterval(intervalId);    };  }, [size]);
  return (    
);}; export default () => { return ;};
令我诧异的是,呼应不只充足好,并且可读性也很强。

上述组件的实践运转状况以下:

比拟输入后果,LLM 呼应仿佛疏忽了一些完成细节,但它依然是一个值得进修的好完成。那相对是一个我之前从已思索过的奇妙用例!
