How to make image slider respond to thumb swipe

Hi I am using the basic W3 slideshow layout but It is not very good for the mobile version of my site.
I searched very hard to find a solution to this but it's always download some plug-in to make it work or something that doesn't respond very well to swipes
$('.slider').on('touchstart', function(event) {
const xClick = event.originalEvent.touches[0].pageX;
$(this).one('touchmove', function(event) {
const xMove = event.originalEvent.touches[0].pageX;
const sensitivityInPx = 5;
if (Math.floor(xClick - xMove) > sensitivityInPx) {
$(this).slider('next');
}
else if (Math.floor(xClick - xMove) < -sensitivityInPx) {
$(this).slider('prev');
}
});
$(this).on('touchend', function() {
$(this).off('touchmove');
});
});
let slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
let i;
let slides = document.getElementsByClassName("mySlides");
let dots = document.getElementsByClassName("dot");
if (n > slides.length) {
slideIndex = 1
}
if (n < 1) {
slideIndex = slides.length
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex - 1].style.display = "block";
dots[slideIndex - 1].className += " active";
}

Even though this is not pure Js and it is a different approach
I found that flickity.js and css is good for mobile and it's just 2 ajax calls like jquery

Like i wrote in the comments, you have two typos: $(this).one('touchmove and .slider, which has to be $(this).on('touchmove and #slider.
But the main problem is your function slider(), which isn't defined. But you can use the function plusSlides(), that you are already using for the next and prev buttons.
Furthermore the touchmove event is firing very often until the touchend event is fired. Therefor the function plusSlides() is called multiple times. To fix this, stop the touchmove event listener when the function plusSlides() is called.
Working example:
$('#slider').on('touchstart', function(event) {
const xClick = event.originalEvent.touches[0].pageX;
$(this).on('touchmove', function(event) {
const xMove = event.originalEvent.touches[0].pageX;
const sensitivityInPx = 5;
if (Math.floor(xClick - xMove) > sensitivityInPx) {
plusSlides(1);
$(this).off('touchmove');
}
else if (Math.floor(xClick - xMove) < -sensitivityInPx) {
plusSlides(-1);
$(this).off('touchmove');
}
});
});
let slideIndex = 1;
showSlides(slideIndex);
function plusSlides(n) {
showSlides(slideIndex += n);
}
function currentSlide(n) {
showSlides(slideIndex = n);
}
function showSlides(n) {
let i;
let slides = document.getElementsByClassName("mySlides");
let dots = document.getElementsByClassName("dot");
if (n > slides.length) {
slideIndex = 1
}
if (n < 1) {
slideIndex = slides.length
}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");
}
slides[slideIndex - 1].style.display = "block";
dots[slideIndex - 1].className += " active";
}

How do I get the canvas to show behind my HTML so my animated cursor will move over the screen?

I want the canvas to show behind the website not over it. I have tried using z index and that does not work. I want to be able to see my actual website while moving the cursor over things. So I need the cursor to show on the website. It just blocks out my whole section. How can I get this to work correctly?
const navToggle = document.querySelector('.nav-toggle');
const navLinks = document.querySelectorAll('.nav__link')
navToggle.addEventListener('click', () => {

link.addEventListener('click', () => {
document.body.classList.remove('nav-open');
})
})

y: undefined
}
canvas.addEventListener('mousemove', function (event) {
mouse.x = event.x;
mouse.y = event.y;
for (let i = 0; i < 3; i++) {
spots.push(new Particle());
}
});

how to fix this Javascript Image Slideshow Error?

I tried to make an image slideshow on javascript but when I run it the first image doesn't show up until I hit the dot or previous and next button. It doesn't show any error too but the image just doesn't show up for the first time. This code consists of Javascript, HTML, and CSS. I need to finish this by tomorrow so anyone that can help me with this?
<script type="text/javascript">
var slideIndex = 1;
showSlides(slideIndex);

var i;
var slides = document.getElementsByClassName("picture");
var dots = document.getElementsByClassName("dot");
if (n > slides.length) {slideIndex = 1}
if (n < 1) {slideIndex = slides.length}
for (i = 0; i < slides.length; i++) {
slides[i].style.display = "none";
}
for (i = 0; i < dots.length; i++) {
dots[i].className = dots[i].className.replace(" active", "");

HTML/CSS/JavaScript: Can't click slideshow indicator button

I'm new to webpage design and am trying to add indicator dots on my slideshow, so when clicking on them, i can go to the next image.
see this image
image2
I initially followed the instructions on the W3School page: https://www.w3schools.com/howto/howto_js_slideshow.asp
which put the indicator dots under the tag and below the slideshow banner. However, I want to put the dots ON the slideshow banner so I changed the tag to , but then the JavaScript stopped working.
In short, what I'm looking for is like the "another example" slideshow banner on this page: https://www.w3schools.com/w3css/w3css_slideshow.asp
sadly, the code used on that page was incomplete and i can't directly copy and paste it onto my website.
Please help to see what's wrong with my code OR to save your time, simply let me know how to achieve the feature mentioned in the above paragraph. Thank you so much.
