Tearable Cloth simulation works on Codepen but not locally

Tearable Cloth simulation works on Codepen but not locally - javascript

I am trying to include this Codepen into a basic website for school.
The issue is that the code with a few tweaks, will not load locally. I have even put my entire website into Codepen as a test and it worked.
It should just be the cloth simulation and nothing else.
Here is the HTML and CSS in its smallest form.
<!doctype html>
<html>
<head>
<style>
body {
background: #2F4F4F;
}
#c {
display: block;
margin: 20px auto 0;
}
</style>
<meta charset="utf-8">
<title>Test</title>
<script type="text/javascript" src="Website/JavaScript/ClothSimulation.js"></script>
</head>
<body>
<canvas id="c"></canvas>
<div id="top">
<a id="close"></a>
</div>
</body>
</html>
The JS is very big as it is a cloth simulation.

Thank you for your help.

Assuming you have copy and pasted the website exactly how it is, you're missing opening and closing style tags around the CSS, and script tags around the JS.

Your code works, but you need this tags:
<script type="text/javascript"> YOUR JAVASCRIPT HERE </script>
<style type="text/css"> YOUR CSS HERE </style>

Tried making a button, that takes you to google page

i have a html script with button and onclick function script that should take me to google.com, but it doesn't seem to work. Been stuck with this for hours. Im also new to HTML.
Tried everything. Line 336 and 353 should be the needed content. And line 136 should be the button itself. I don't understand whats wrong. Anyone ever have had this issue?

If you're trying to make a button that takes you to google.com, I would advise you to use an a tag, not a button tag. The tag automatically links you to your desired destination when clicked.
Example:
Example
If you want the link to look like a button, then simply look at the css options. I would advise you to look here: https://www.w3schools.com/css/css_link.asp
a {
background-image:linear-gradient(to bottom, lightblue, aquamarine);
padding:5px;
text-decoration:none;
color:black;
padding-right:50px;
padding-left:50px;
margin-top: 50px;
margin-left: 50px;
display: inline-block;
font-size:25px;
border-radius:5px;
box-shadow: 1px 1px green;
}
Example
If you are determined to use a <button> tag, then all you need to do is within that button tag add an onclick attribute. So, you would change your code to <button id="btncmd" onclick="cmd()">Videos</button>.
Example of what you want:
function cmd() {
window.location.href = "https://www.example.com/"; // I'm using example but you can use google.
}
<button id="btncmd" onclick="cmd()">Videos</button>

You did not define btncmd. Adding this line to your code solves the problem:
var btncmd = document.getElementById("btncmd");

How to execute Javascript in front of the page Wordpress?

Been trying to run different js scripts on Wordpress in front of the page itself but everytime I try, it ends up creating a specific div with given width and height which stays on top of the page.
I was hoping the script itself would run "over" any div on page as an animated effect (on mouse move)
This is particularly one of the scripts I would like to run through all the pages:
<!DOCTYPE html>
<html lang="en" >

top: 10px;
}
#info {
background: rgba(0,0,0,0.8);
padding: 12px 10px;
margin-bottom: 1px;
color: #fff;
}
#info h1 {
line-height: 22px;
font-weight: 300;
font-size: 18px;
margin: 0;
}
#info h2 {
line-height: 14px;
font-weight: 300;
font-size: 12px;
color: rgba(255,255,255,0.8);

I would like the particles to run through the site.
Any help with it?

First I would start by making sure you properly enqueue the your javascript and css:
https://codex.wordpress.org/Plugin_API/Action_Reference/wp_enqueue_scripts
wp_enqueue_scripts is the proper hook to use when enqueuing items that
are meant to appear on the front end.

Trying to run one function after the other using JS

I've been having some trouble running one function that slowly displays a message, waits, then fades out. However, you'll notice when the button is clicked to drop the confetti and display the message, the confetti doesn't stop.
I'm still learning Javascript, and am not that experienced with it yet. But I pieced this together to get what I'm looking for as an end result.
What I'd like to happen is when the button is clicked, the message fades in, confetti falls, message fades and confetti stops falling but allows the last bit of confetti to fall until its off screen...
It's probably because I don't understand Javascript to this level yet, but I'm having a really hard time getting the JS to do what I'm wanting...
Can anyone give me some pointers in my code to help guide me in the right direction?
Thanks!!

The fadeOut() has one callback where you pass what should happen when animation is over.You must have tried this but reason why it didn't work is that most of your js code is in a self executing function which forms a different scope so you cannot call any method inside this scope from outside.I have moved the stuff inside now it works.Not much change there just changed a few lines; marked with NEWLY ADDED

Add 3 color components to image data. For example, for orange color:
for (realX = goodX - resHalfFloor; realX <= goodX + resHalfCeil && realX >= 0 && realX < cw; realX++) {
for (realY = goodY - resHalfFloor; realY <= goodY + resHalfCeil && realY >= 0 && realY < ch; realY++) {
index = (realY * imageData.width + realX) * 4;
actualData[index + 0] = 253; // Red component
actualData[index + 1] = 106; // Green component
actualData[index + 2] = 2; // Blue component
actualData[index + 3] = 255;
}
}

Canvas responsive scroll

I use sketch.js plugin in my website but If I use it will be not responsive and the horizontal scroll will be appear I don't need to depend on body { overflow: hidden }so what is the solution:
Here my code:
// ----------------------------------------
// Particle
// ----------------------------------------
function Particle(x, y, radius) {
this.init(x, y, radius);
}
Particle.prototype = {
init: function (x, y, radius) {
this.alive = true;
this.radius = radius || 10;
this.wander = 0.15;
this.theta = random(TWO_PI);
this.drag = 0.92;
this.color = '#fff';
this.x = x || 0.0;
this.y = y || 0.0;
this.vx = 0.0;
this.vy = 0.0;
},
move: function () {
this.x += this.vx;
this.y += this.vy;
this.vx *= this.drag;
this.vy *= this.drag;
this.theta += random(-0.5, 0.5) * this.wander;
this.vx += sin(this.theta) * 0.1;
this.vy += cos(this.theta) * 0.1;
this.radius *= 0.96;
this.alive = this.radius > 0.5;
},
draw: function (ctx) {
ctx.beginPath();
ctx.arc(this.x, this.y, this.radius, 0, TWO_PI);
ctx.fillStyle = this.color;
ctx.fill();
}
};
