Question

我几乎在互联网上搜索过，而且我已经非常接近答案，但我仍然无法弄清楚如何在网站中使用p5.js。更具体地说，我希望能够创建一个weebly，并让它显示p5代码。我知道它涉及网站通过文件或在线文件和sketch.js加载p5.js。如果没有办法在网上使用p5.js，有没有办法在互联网上使用一般（或类似的）处理代码？感谢

Answer 1

请按照以下说明操作：http://p5js.org/get-started/

或这些说明：https://github.com/processing/p5.js/wiki/Embedding-p5.js

基本上，你需要创建一个使用p5.js的html文件，你应该已经拥有它。

然后您只需要将该html文件以及您正在使用的任何资源上传到某种类型的网络主机。

您可能还想查看标准处理编辑器附带的Processing.js。

Answer 2

如果您使用Mac或Windows编辑器（本文撰写的0.5.7版（0.5.7））创建草图，请转到“另存为”，编辑器将导出“Web就绪”文件。

您保存的文件将与草图具有相同的名称，并包含index.html和sketch.js文件以及“libraries”文件夹。您可以按原样发布.html和.js文件，并检查.html以获取指向p5 .js库的链接。

<script src="libraries/p5.js" type="text/javascript"></script>
<script src="libraries/p5.dom.js" type="text/javascript"></script>
<script src="libraries/p5.sound.js" type="text/javascript"></script>
<script src="sketch.js" type="text/javascript"></script>

Answer 3

创建html文件和sketch.js文件

在您的html文件中，您可以放入初学者模板，然后在sketch.js中添加p5js

// All the paths
var paths = [];
// Are we painting?
var painting = false;
// How long until the next circle
var next = 0;
// Where are we now and where were we?
var current;
var previous;

function setup() {
  createCanvas(720, 400);
  current = createVector(0,0);
  previous = createVector(0,0);
};

function draw() {

  // If it's time for a new point
  if (millis() > next && painting) {

    current.x = mouseX;
    current.y = mouseY;

    // New particle's force is based on mouse movement
    var force = p5.Vector.sub(current, previous);
    force.mult(0.05);

    // Add new particle
    paths[paths.length - 1].add(current, force);
    
    // Schedule next circle
    next = millis() + random(100);

    // Store mouse values
    previous.x = current.x;
    previous.y = current.y;

  // Draw all paths
  for( var i = 0; i < paths.length; i++) {
    paths[i].update();
    paths[i].display();

// Start it up
function mousePressed() {
  next = 0;
  painting = true;
  previous.x = mouseX;
  previous.y = mouseY;
  paths.push(new Path());

// Stop
function mouseReleased() {
  painting = false;
}

// A Path is a list of particles
function Path() {
  this.particles = [];
  this.hue = random(100);
}

Path.prototype.add = function(position, force) {
  // Add a new particle with a position, force, and hue
  this.particles.push(new Particle(position, force, this.hue));
}

// Display plath
Path.prototype.update = function() {  
  for (var i = 0; i < this.particles.length; i++) {
    this.particles[i].update();
  }

// Display plath
Path.prototype.display = function() {

    if (this.particles[i].lifespan <= 0) {
      this.particles.splice(i, 1);
    // Otherwise, display it
    } else {
      this.particles[i].display(this.particles[i+1]);

}

Particle.prototype.update = function() {

  stroke(0, this.lifespan);
  fill(0, this.lifespan/2);    
  ellipse(this.position.x,this.position.y, 8, 8);

您可以像使用它一样

<html>
  <head>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/p5.js/0.8.0/p5.js"></script>
    <script>
      function setup() {
        createCanvas(400, 400)
      }
      
      function draw() {
        background(220);
      }
    </script>
  </head>
  <body>
  </body>
</html>

但是，如果您使用webpack，那么我认为此链接可以帮助您了解如何使用它Learning the P5 Drawing Library With ES6 and Webpack

webpack中的问题在于，我们无法将setup()，draw()用作全局范围，如以下代码片段所示。

// $npm i p5 --save(save to package.json)
import * as p5 from 'p5';

let s = (sk) => {
    sk.setup = () => {
        sk.createCanvas(400, 400);
    };

    sk.draw = () => {
        sk.background(220);
    }
};

const P5 = new p5(s);
