I was looking into one of the only few full page scroll codes which I have found so far, and wanted to somehow get the idea of what I should do by reversing the engineering but I'm noob and not good at understanding it pretty well, I don't understand it well and I get stock at every line, can you please explain to me what the guy has done? Whats the basics of what he is doing ..variables and functions and what they are in this case and why we need them? A summary on what is going on.
this is the link to the code
https://codepen.io/igstudio/pen/pbYOab
this is the JS code
(function() {
"use strict";

Thanks.
I was trying to do a full page scroll while using anchor links throughout the page but sometimes it won't scroll up anymore or the links stop working or go to the wrong places. It gets pushed down leaving strange white space after I scroll around an press on the links.

Hi there I have a parallax effect scroll on my website, it is all working good on desktop but mobile device it is not working properly when I attempt to even scroll/swipe down the page.
Here is the javascript:
var ticking = false;
var isFirefox = /Firefox/i.test(navigator.userAgent);
var isIe = /MSIE/i.test(navigator.userAgent) || /Trident.*rv\:11\./i.test(navigator.userAgent);
var scrollSensitivitySetting = 30;
var slideDurationSetting = 800;
var currentSlideNumber = 0;
var totalSlideNumber = $('.background').length;
function parallaxScroll(evt) {
if (isFirefox) {
delta = evt.detail * -120;
} else if (isIe) {
delta = -evt.deltaY;
} else {
delta = evt.wheelDelta;
}
if (ticking != true) {
if (delta <= -scrollSensitivitySetting) {
ticking = true;
if (currentSlideNumber !== totalSlideNumber - 1) {
currentSlideNumber++;
nextItem();
}
slideDurationTimeout(slideDurationSetting);
}
if (delta >= scrollSensitivitySetting) {
ticking = true;
if (currentSlideNumber !== 0) {
currentSlideNumber--;
}
previousItem();
slideDurationTimeout(slideDurationSetting);
}
}
}
function slideDurationTimeout(slideDuration) {
setTimeout(function () {
ticking = false;
}, slideDuration);
}
var mousewheelEvent = isFirefox ? 'DOMMouseScroll' : 'wheel';
window.addEventListener(mousewheelEvent, _.throttle(parallaxScroll, 60), false);
function nextItem() {
var $previousSlide = $('.background').eq(currentSlideNumber - 1);
$previousSlide.css('transform', 'translate3d(0,-130vh,0)').find('.content-wrapper1').css('transform', 'translateY(40vh)');
currentSlideTransition();
}
function previousItem() {
var $previousSlide = $('.background').eq(currentSlideNumber + 1);
$previousSlide.css('transform', 'translate3d(0,30vh,0)').find('.content-wrapper1').css('transform', 'translateY(30vh)');
currentSlideTransition();
}
function currentSlideTransition() {
var $currentSlide = $('.background').eq(currentSlideNumber);
$currentSlide.css('transform', 'translate3d(0,-15vh,0)').find('.content-wrapper1').css('transform', 'translateY(15vh)');
;
}
Your help would be appreciated thank you!
setInterval "MoveToPlayer" should start after meeting first condition from "checkPosition" method and it should run(this works). After meeting the same condition again it should stop and start again with different parameter. I through that simple placing clearInterval(MoveToPlayer) will do the job but it doesn't work.
Second issue is how to stop this interval for example from "checkPosition" method?
class player {
constructor(name, PosY) {
this.name = name;
this.PosX = 5;
this.PosY = PosY;
this.object = $('.' + name);
this.speed = 0;
this.direction = "";
this.lifes = 3;
}
playerMove(thisRaft) {
var MoveToPlayer = setInterval(() => {
clearInterval(MoveToPlayer)
$('.player1').css('left', thisRaft.PosX * 50);
$('.player1').css('bottom', thisRaft.PosY * 50);
}, 1);
}
checkPosition(x, y) {
for (var i = 0; i < raftsTab.length; i++) {
if (x == raftsTab[i].PosX && y == raftsTab[i].PosY) {
let thisRaft = raftsTab[i];
this.playerMove(thisRaft);
return;
}
}
for (var i = 0; i < raftsTab.length; i++) {
if (x !== raftsTab[i].PosX && y !== raftsTab[i].PosY && y !== 0 && y !== 5 && y !== 10) {
console.log("Dead");
player1.PosX = 5;
player1.PosY = 0;
changePosition();
return;
}
}
}
}
Regarding your first issue you are clearing the interval immediately after it starts, so it won't continue.
In order to make the interval more dynamic you should have a function that returns an interval within checkPosition.
Wasn't able to understand how your game should actually work, but I am posting an alteration to your script where I modified PlayerMove and checkPosition in away that gives you a better control of the interval in question.
Hope it is clear and helpful for you
class player {
constructor(name, PosY) {
this.name = name;
this.PosX = 5;
this.PosY = PosY;
this.object = $('.' + name);
this.speed = 0;
this.direction = "";
this.lifes = 3;
}
playerMove(thisRaft) {
return setInterval(() => {
$('.player1').css('left', thisRaft.PosX * 50);
$('.player1').css('bottom', thisRaft.PosY * 50);
}, 1);
}
checkPosition(x, y) {
if (someCondition && this.currentPlayerMove) {
clearInterval(this.currentPlayerMove)
}
for (var i = 0; i < raftsTab.length; i++) {
if (x == raftsTab[i].PosX && y == raftsTab[i].PosY) {
let thisRaft = raftsTab[i];
this.currentPlayerMove = this.playerMove(thisRaft);
return;
}
}
for (var i = 0; i < raftsTab.length; i++) {
if (x !== raftsTab[i].PosX && y !== raftsTab[i].PosY && y !== 0 && y !== 5 && y !== 10) {
console.log("Dead");
player1.PosX = 5;
player1.PosY = 0;
changePosition();
return;
}
}
}
Just assign your handler at such scope, that would make it accessible to all functions that could clear it.
var handler;
function movePlayer(text){
clearInterval(handler); // stop execution before assigning new handler
handler = setInterval(()=>{
/* do your stuff */
console.log(text);
}, 100)
}
movePlayer("I'm moving")
setTimeout(()=>{
clearInterval(handler)
}, 500)
setTimeout(()=>{
movePlayer("I'm moving again")
}, 1500)
setTimeout(()=>{
clearInterval(handler)
}, 2000)
On my HTML page, I need to have a line with text that rolls "infinitely" on the page, e.g.
"Hello World ... Hello World ... Hello World ... Hello World ..."
Sort of like a ticker tape, but with the same text's beginning rolling into its end w/o a gap.
I've tried using animation: marquee CSS style, I can get the text roll, then jump back, then roll again, but that's not what I need.
Is this possible with CSS? JS would be OK, if there is a working solution.
Try here "text rolling" working with text & images and mouse effects(js+css)

Are you open to using a lib that does this?
This one here: http://www.cssscript.com/marquee-like-horizontal-scroller-with-pure-javascript-marquee-js/ does a good job.

Here is a demo based upon the lib that Dreamer posted.
I didn't like how it set inline styles on the element or how it used cookies to store past settings so I removed that in the crawler.js code.
This is a pretty old library (ie5 is mentioned (!)) but it seems to do the trick.
$(function() {
marqueeInit({
uniqueid: 'mycrawler',
style: {
},
inc: 5, //speed - pixel increment for each iteration of this marquee's movement
mouse: 'cursor driven', //mouseover behavior ('pause' 'cursor driven' or false)
moveatleast: 2,
neutral: 150,
persist: true,
savedirection: true
});
