AnimeJS Motion Path - Make element follow SVG path giving undesirable result - javascript

I'm trying to get the orange marker to follow the course of this RC car race track using an SVG element and the AnimeJS library.
But no matter what I try, I get really strange and undesirable results.
Sometimes I can see the marker following the path but the path it's on is offset from the course and not in the same scale, and some things I try I cannot see the marker at all but I can see the scrollbars on my page altering, which indicates that the marker is there and is moving.
I can also look at the browser's inspect tool and can see that the element's styles are changing rapidly - translateX, translateY and rotate.
The code, as I've left it here, shows the marker is moving. If you look carefully in the JSFiddle demo, and wait 9.49seconds for each lap to complete, you can see a flash of an orange ball for a nano-second but the ball isn't to scale and I have no idea what path it's following.
What am I doing wrong? How can this be achieved? I'm open to using other libraries or tools if it helps.

easing: 'linear',
duration: 9490, // fastest lap on course
loop: true
});

I guess I am too late to be useful for you but:
tl;dr
The whole problem is that transform origin is kind of broken in SVGs and anime.js is a simple tool. To fix this you have to place the animating object (the circle) to cx="0" cy="0" and remove any transforms on the path.
More info
Really helpful article on SVG transform is here on CSS Tricks. The important think from there is: transform of all elements inside svg element has transform origin in upper left corner of the svg element.
If you inspect the transforms that anime.js creates on the animated element you will see exactly the values from the path's d attribute. Those values are number of pixels from origin (again upper left corner of the svg element) however when there is transform applied to the element it will not match.

JS - Copy colour value to another elements

I'm trying to copy the color value from the <h1> element to <path> elements.
<div id='my_id'>
<h1 style='color:orange'>What What</h1>
<div id='my_element'>
<svg>
<path d="M10 10"></path>
<path d="M10 10"></path>
<path d="M10 10"></path>
</svg>
</div>
</div>
mycolor_element = document.querySelectorAll('#my_id h1')[0];
let my_value = window.getComputedStyle(mycolor_element).color;
document.querySelectorAll('#my_element svg path')[0].style.fill = my_value;
I expect that if my <h1> is orange then my <path>s are also orange.
You can use querySelector (if is just one element) with window.getComputedStyle for catch color of element then set it to the svg like:
const mycolor_element = window.getComputedStyle(document.querySelector('#my_id > h1')).color;
document.querySelectorAll('#my_element > svg > path').forEach(el => el.style.fill = mycolor_element);
h1 {
color: orange
}
<div id='my_id'>
<h1 style='color:orange'>What What</h1>
<div id='my_element'>
<svg>
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 0 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 15 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 30 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
</svg>
</div>
</div>
You can simplify this task by applying a fill:currentColor property value to your <path> elements:
path{
fill:currentColor;
}
This way all paths can inherit the fill color from the parent element's (text) color property:
let h1 = document.querySelector('#my_id h1');
let h1Color = window.getComputedStyle(h1).color;
let svgWrap = document.getElementById('svgWrap');
svgWrap.style.color = h1Color;
.colorOrange{
color:orange
}
.svgCurrentColor path{
fill:currentColor;
}
<div class='colorOrange'>
<h1>Inherit color via css</h1>
<div class='svgWrap'>
<svg class="svgCurrentColor">
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 0 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 15 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 30 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
</svg>
</div>
</div>
<div id='my_id'>
<h1 style="color:purple">Inherit color via js</h1>
<div id='svgWrap' >
<svg class="svgCurrentColor">
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 0 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />
<path fill="rgb(0,0,0)" fill-opacity="1" d=" m 44 15 c 0 0 0 10 0 10 c 0 0 -88 0 -88 0 c 0 0 0 -10 0 -10 c 0 0 88 0 88 0 z" />

So you might not need any javaScript at all.
document.querySelectorAll
This method is not used to select one element only.
Use the
document.querySelector
method instead.

Showing and not showing the shopping cart item count

Using the following codes, I display the number of products in the shopping cart numerically next to the shopping cart icon.
HTML:
<div class="ico-shop">
<a href="<?php echo wc_get_cart_url(); ?>">
<button class="ico-shop_btn">

</button>
<span class="counting_cart_items"><?php echo WC()->cart->get_cart_contents_count(); ?></span>
</a>
</div>
CSS:
.ico-shop button {
background: none;
border: none;
outline: none;
list-style: none;
padding-right: 17px;
border-right: 2px solid #afb1b5;
}
.ico-shop {
position: relative;
}
.counting_cart_items {
position: absolute;
top: 18px;
right: 3px;
font-size: 12px;
background: #52abff;
color: #fff;
text-shadow: none;
padding: 1px 7px;
border-radius: 50%;
}
PHP (In the function file):
function custom_cart_count_fragments( $fragments ) {
$fragments[ 'div.cart-totals' ] = '<div class="cart-totals">' . WC()->cart->get_cart_contents_count() . '</div>';
return $fragments;
}
Result:
But I don't want this number to be displayed when there are no items in the cart.
For this purpose, I wrote the following script code, which does not work:
script:
var cart_item = document.querySelector(".counting_cart_items");
$(cart_item).each(function () {
if ($(this) == 0) {
$(this).css("display", "none");
} else {
$(this).css("display", "block");
}
});
Is there a way to solve this problem?
Why not something like
<div class="ico-shop">
<a href="<?php echo wc_get_cart_url(); ?>">
<button class="ico-shop_btn">

</svg>
</button>
<?php if (WC()->cart->get_cart_contents_count() > 0) { ?>
<span class="counting_cart_items"><?php echo WC()->cart->get_cart_contents_count(); ?></span>
<?php } ?>
</a>
</div>
Or (only pertinent line included here)
<span class="counting_cart_items" style="display: <?php echo (WC()->cart->get_cart_contents_count() > 0 ? "block" : "none"); ?>><?php echo WC()->cart->get_cart_contents_count(); ?></span>
Alternatively, you could give the span an ID, then use document.getElementByID(<id>).style.display = <block/none>. I suspect $(this) == 0 may also not be working as you intend it to. I would need more information to comment on how to do more in JS

SVG Clock - Transform origin not working on the lancets

I am trying to reproduce something that I saw a while ago which is animating an SVG clock. Everything works fine but I can't get around the transform-origin which seems not to be working... is the way the path is made?
// Real time clock animation
let sec = document.querySelector('.seconds-lancet');
let min = document.querySelector('.minutes-lancet');
let hour = document.querySelector('.hours-lancet');
setInterval(function() {
let d = new Date();
function r(el, deg) {
el.setAttribute('transform', 'rotate('+ deg +')');
}
r(sec, 6*d.getSeconds());
r(min, 6*d.getMinutes());
r(hour, 30*(d.getHours()%12) + d.getMinutes()/2);
}, 1000);
.seconds-lancet,
.minutes-lancet,
.hours-lancet {
transform-origin: bottom center !important;
}

Thanks
Looks like you've assumed that the transform-box is the fill-box, it's not by default it's the view-box. Setting transform-box: fill-box; seems to make things work better.
// Real time clock animation
let sec = document.querySelector('.seconds-lancet');
let min = document.querySelector('.minutes-lancet');
let hour = document.querySelector('.hours-lancet');
setInterval(function() {
let d = new Date();
function r(el, deg) {
el.setAttribute('transform', 'rotate('+ deg +')');
}
r(sec, 6*d.getSeconds());
r(min, 6*d.getMinutes());
r(hour, 30*(d.getHours()%12) + d.getMinutes()/2);
}, 1000);
.seconds-lancet,
.minutes-lancet,
.hours-lancet {
transform-origin: bottom center !important;
transform-box: fill-box;
}

Bitmap to svg path

I don't know how to make this algorithm in JavaScript/Node.js that converts bitmaps into svg paths pixel by pixel:
// input
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
0 0 1 1 1 1 1 1 0 0
0 0 1 1 1 1 1 1 0 0
0 1 1 1 0 0 1 1 1 0
0 1 1 1 0 0 1 1 1 0
0 0 1 1 1 1 1 1 0 0
0 0 1 1 1 1 1 1 0 0
0 0 0 0 0 0 0 0 0 0
0 0 0 0 0 0 0 0 0 0
// output
<path d="M2 2 h6 v2 h1 v2 h-1 v2 h-6 v-2 h-1 v-2 h1 v-2 M4 4 v2 h2 v-2 z">
Does anyone know how the algorithm should work?
Any pseudocode would help.
Tools does the similar approach:
https://github.com/59naga/pixel-to-svg
https://github.com/brainshave/sharpvg
https://codepen.io/shshaw/pen/XbxvNj
http://drububu.com/tutorial/bitmap-to-vector.html
You can converts pixels to SVG path string like this.
Using this algorithm, I made script coverts pixel art to SVG.

Explore matrix for adjacent duplicates (find connections)

I am making a folt clone for fun and I am having trouble with the explore function. Basically I want to reset grid locations when the connected tiles > 3. Here is an example of what might happen during the game...
current_position=[3,4]
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 2 2 0
0 0 0 1 0 0
0 0 0 1 2 3
move(down)
current_position=[4,4]
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 2 2 0
0 0 0 1 2 0
0 0 0 1 2 3
resetGridLocations(explore([4,4]))
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 0 0 0
0 0 0 1 2 0
0 0 0 1 0 3
score += 3
Here is a JS bin of my source code for the game. You can play the semi-functional version by calling move(keyCode) in the console. Currently the explore() function searches 2 layers around the position for duplicate values. It works for the above example but not for larger groups like below. A recursive solution seems attractive.
0 0 0 0 0 0
0 0 0 0 2 0
0 0 1 1 2 0
0 0 0 2 2 0
0 0 0 1 2 0
0 0 0 1 2 3
