The if condition only works with an alert and the position is reset?

The code is that the player goes to where the user clicks, but now I want the character to look at the X axis where it goes.
The problem is that it only works when you have an alert, but only if the alert gives an error because if the alert does not give an error it does not work.
The other problem is that the transform translate3d is deleted then the player returns to the same position although the scaleX changes.
I'm new to jquery and I have no idea.
$(document).on("click mousedown", "#Park", function(e) {
var x = e.clientX;
var y = e.clientY;
var newposX = x - 60;
var newposY = y - 60;
var n = $(".circle").offset()
if (newposX < n.left) {
$(".circle").css("transform", "scaleX(-1)");
alert(ok)
}
$(".circle").css("transform", "translate3d(" + newposX + "px," + newposY + "px,0px)");
setTimeout(function() {
$(".circle3").css("display", "none");
$(".circle2").css("display", "block");
}, 2000);
$(".circle2").css("display", "none");
$(".circle3").css("display", "block");
});

Immediately after the conditional, you're overwriting the transform with a new value, which means the scaleX() is immediately overwritten unless your code breaks at the alert().
Instead, write your conditional like this, to ensure the scaleX() doesn't get overwritten when you set the translate3d():
if (newposX < n.left) {
$(".circle").css("transform", "scaleX(-1) translate3d(" + newposX + "px," + newposY + "px,0px)");
} else {
$(".circle").css("transform", "translate3d(" + newposX + "px," + newposY + "px,0px)");
}
Alternatively, you could write it like this, which is easier to read in my opinion:
let transform = `translate3d(${newposX}px, ${newposY}px, 0px)`;
if (newposX < n.left) {
transform = 'scaleX(-1) ' + transform;
}
$('.circle').css('transform', transform);

On mousemove translate div position within a specified range

I have a wrapper called #mousearea and I have a div called #mouseshift what I would like to do is when I hover over #mousearea I would like to shift the translate3d(0,230%,0) value between a particular range.
I have got the mousemove working but I currently end up with something like translate3d(7881%,230%,0) it's just too sensetive I would like it to translate the X co-ordinate between something like 0-60% so it's far more subtle.
Here is what I have so far:
jQuery(document).ready(function($){
$('#mousearea').mousemove(function (e) {
var shiftAmount = 1;
$('#mouseshift').css(
'transform', 'rotate(90deg) translate3d(' + -e.pageY + shiftAmount + '%,230%,0)'
);
});
});
Update:
This is a little closer, except it logs the correct translate3d but doesn't apply it to #mouseshift.
$('#mousearea').mousemove(function(e){
var x = e.pageY - this.offsetTop;
var transfromPosition = 'translate3d(' + x + ', 230%, 0)';
console.log(transfromPosition);
if ((x <= 800)) {
//$('#mouseshift').css({'top': x});
$('#mouseshift').css('transform', transfromPosition);
}
});
Final Solution:
jQuery(document).ready(function($){
$('#mousearea').mousemove(function(e){
var min = 50;
var max = 70;
var x = e.pageY;
var windowHeight = window.innerHeight;
scrolled = (x / windowHeight);
percentageScrolled = scrolled * 100;
offsetScroll = max - min;
offsetPercentage = scrolled * 20;
translateX = min + offsetPercentage;
console.log(x + 'px');
console.log(windowHeight + 'px window height');
console.log(percentageScrolled + '% scrolled');
console.log(offsetScroll + 'offset scroll');
console.log(offsetPercentage + '% offset percentage');
var transfromPosition = 'rotate(90deg) translate3d(' + translateX + '%, 230%, 0)';
$('#mouseshift h1').css('transform', transfromPosition);
});
});
Convert to a reusable plugin I would like to extend this to work with more than one object now and each object would have a different max and min value:
This is what I have but it seems to effect all the items on only use on elements max and min.
$(function () {
$('#mouseshift-1, #mouseshift-2').mouseShift();
});
(function ($) {
$.fn.mouseShift = function () {
return this.each(function () {
var myEl = $(this);
var min = $(this).data('min');
var max = $(this).data('max');
$('#mousearea').mousemove(function (e) {
var yPosition = e.pageY;
var windowHeight = window.innerHeight;
scrolled = (yPosition / windowHeight);
//percentageScrolled = scrolled * 100;
offsetRange = max - min;
offsetRangePercentage = scrolled * 20;
offset = min + offsetRangePercentage;
//// Debug
console.log('max: ' + max + ', Min:' + min);
console.log(yPosition + 'px');
console.log(windowHeight + 'px window height');
//console.log(percentageScrolled + '% scrolled');
console.log(offsetRange + 'px offset scroll');
console.log(offsetRangePercentage + '% offset percentage');
var transfromPosition = 'rotate(90deg) translate3d(' + offset + '%, 230%, 0)';
myEl.css('transform', transfromPosition);
});
});
};
})(jQuery);
And some HTML for clarity:
<div class="column"><h1 id="mouseshift-1" data-min="50" data-max="70">boo</h1></div>
<div class="column"><h1 id="mouseshift-2" data-min="20" data-max="90">bah</h1></div>
<div class="column"><h1 id="mouseshift-3" data-min="80" data-max="100">bing</h1></div>

I think what you are looking for is finding an average that your can distribute. The best way to do this is to divide by the maximum amount it can move, and multiply it by the maximum value it can have, so basically:
position / maxposition * maxvalue
The first bit will return a number between 0 and 1, while the last bit will make it the value between 0 and 60. Below I have built a simply (jquery-less) version of it to show how this would work:
var mousePointer = document.getElementById('test')
document.addEventListener('mousemove', function(e){
var x = e.pageX / window.innerHeight;
x = x * -60;
mousePointer.style.webkitTransform = 'translateX(' + x + '%)';
mousePointer.style.transform = 'translateX(' + x + '%)';
})
#test {
position: absolute;
left: 50%;
top: 50%;
width: 20px;
height: 20px;
background: red;
}
<div id="test"></div>
Update: Reusable Snippet
I don't really like using jQuery, so once again it will be vanilla javascript (but it's pretty simple). Is that what you were - sort of - trying to do with the reusable plugin?
var divs = Array.prototype.slice.call(document.querySelectorAll('[data-range]'));
document.addEventListener('mousemove', function(e){
var eased = e.pageX / window.innerWidth;
divs.forEach(function(div){
var range = div.getAttribute('data-range').split(',');
var min = parseFloat(range[0]);
var max = parseFloat(range[1]);
var ease = min + (eased * (max - min));
div.style.webkitTransform = 'translateX(' + ease + '%)';
div.style.transform = 'translateX(' + ease + '%)';
});
});
div {
position: absolute;
left: 50%;
top: 50%;
width: 200px;
height: 200px;
background: gray;
}
#d2 { background: yellow; }
#d3 { background: #666; }
<div data-range="60,70" id="d1"></div>
<div data-range="-70,70" id="d2"></div>
<div data-range="-60,-70" id="d3"></div>

From simple reading, I see that you're missing a % sign. Should be like this:
$('#mousearea').mousemove(function(e){
var x = e.pageY - this.offsetTop;
var transfromPosition = 'translate3d(' + x + '%, 230%, 0)';
console.log(transfromPosition);
if ((x <= 800)) {
//$('#mouseshift').css({'top': x});
$('#mouseshift').css('transform', transfromPosition);
}
});
This should be working like your first example, where you do use % for both values inside the translate3d string.
Update:
To coerce your x Value to something between 0 and 60, you need to find a pair of possible min and max values for x. Then you can do something like what's shown in this answer:
Convert a number range to another range, maintaining ratio

Dragging elements on a scaled div

I've tried using jquery's built in draggable and I've tried using custom drag functions with no avail. Both have their respected issues and I will try to highlight both of them.
Basically, I am trying to allow the dragging of an element that is on a scaled div container. The following methods work okay on a scaled element that is less than around 2. But if you go any higher than that, we see some issues.
Any help would be appreciated. Thank you for your time.
HTML
<div id="container">
<div id="dragme">Hi</div>
</div>
Method 1 (Jquery draggable function)
I've tried the jquery draggable function as you can see in this jsfiddle example.
The problems I found in this example are the following:
Biggest concern: The droppable container does not change when it is scaled up. So if the element is being dragged over part of the scaled container that isn't a part of it's original size, it will fail.
When you click to drag a div, it teleports a little bit away from the mouse and is not a seamless drag.
JS
var percent = 2.5;
$("#dragme").draggable({
zIndex: 3000,
appendTo: 'body',
helper: function (e, ui) {
var draggable_element = $(this),
width = draggable_element.css('width'),
height = draggable_element.css('height'),
text = draggable_element.text(),
fontsize = draggable_element.css('font-size'),
textalign = draggable_element.css('font-size');
return $('<div id="' + draggable_element.id + '" name="' + draggable_element.attr('name') + '" class="text">' + text + '</div>').css({
'position': 'absolute',
'text-align': textalign,
'background-color': "red",
'font-size': fontsize,
'line-height': height,
'width': width,
'height': height,
'transform': 'scale(' + percent + ')',
'-moz-transform': 'scale(' + percent + ')',
'-webkit-transform': 'scale(' + percent + ')',
'-ms-transform': 'scale(' + percent + ')'
});
},
start: function (e, ui) {
$(this).hide();
},
stop: function (e, ui) {
$(this).show();
}
});
$("#container").droppable({
drop: function (event, ui) {
var formBg = $(this),
x = ui.offset.left,
y = ui.offset.top,
drag_type = ui.draggable.attr('id');
var element_top = (y - formBg.offset().top - $(ui.draggable).height() * (percent - 1) / 2) / percent,
element_left = (x - formBg.offset().left - $(ui.draggable).width() * (percent - 1) / 2) / percent;
$(ui.draggable).css({
'top': element_top,
'left': element_left
});
}
});
Method 2 - Custom drag function
I've tried using a custom drag function but it unusable after around a 2 scale.
jsfiddle on a scale(2) - Looks like the draggable div is having a seizure.
jsfiddle on a scale(2.5) - The draggable div flys away when you try to drag it.
JS
(function ($) {
$.fn.drags = function (opt) {
opt = $.extend({
handle: "",
cursor: "move"
}, opt);
if (opt.handle === "") {
var $el = this;
} else {
var $parent = this;
var $el = this.find(opt.handle);
}
return $el.css('cursor', opt.cursor).on("mousedown", function (e) {
if (opt.handle === "") {
var $drag = $(this).addClass('draggable');
} else {
$(this).addClass('active-handle')
var $drag = $parent.addClass('draggable');
}
var
drg_h = $drag.outerHeight(),
drg_w = $drag.outerWidth(),
pos_y = $drag.offset().top + drg_h - e.pageY,
pos_x = $drag.offset().left + drg_w - e.pageX;
follow = function (e) {
$drag.offset({
top: e.pageY + pos_y - drg_h,
left: e.pageX + pos_x - drg_w
})
};
$(window).on("mousemove", follow).on("mouseup", function () {
$drag.removeClass('draggable');
$(window).off("mousemove", follow);
});
e.preventDefault(); // disable selection
}).on("mouseup", function () {
if (opt.handle === "") {
$(this).removeClass('draggable');
} else {
$(this).removeClass('active-handle');
$parent.removeClass('draggable');
}
});
}
})(jQuery);
$("#dragme").drags({}, function (e) {});

Here are a few of my findings to make sure dragging on a scaled container works for method one. The only caveat is to make sure you have var percent as the scaled percentage declared before any of these actions happen.
First, use this code at the top of your javascript. This wil help making sure that the droppable area works with a sacled container.
$.ui.ddmanager.prepareOffsets = function( t, event ) { var i, j, m = $.ui.ddmanager.droppables[ t.options.scope ] || [], type = event ? event.type : null, list = ( t.currentItem || t.element ).find( ":data(ui-droppable)" ).addBack(); droppablesLoop: for ( i = 0; i < m.length; i++ ) { if ( m[ i ].options.disabled || ( t && !m[ i ].accept.call( m[ i ].element[ 0 ], ( t.currentItem || t.element ) ) ) ) { continue; } for ( j = 0; j < list.length; j++ ) { if ( list[ j ] === m[ i ].element[ 0 ] ) { m[ i ].proportions().height = 0; continue droppablesLoop; }  } m[ i ].visible = m[ i ].element.css( "display" ) !== "none"; if ( !m[ i ].visible ) { continue; } if ( type === "mousedown" ) { m[ i ]._activate.call( m[ i ], event ); } m[ i ].offset = m[ i ].element.offset(); m[ i ].proportions({ width: m[ i ].element[ 0 ].offsetWidth * percent, height: m[ i ].element[ 0 ].offsetHeight * percent }); } };
Here are a few functions that are necessary to fix the drag so it works on a scaled container.
function dragFix(event, ui) { var changeLeft = ui.position.left - ui.originalPosition.left, newLeft = ui.originalPosition.left + changeLeft / percent, changeTop = ui.position.top - ui.originalPosition.top, newTop = ui.originalPosition.top + changeTop / percent; ui.position.left = newLeft; ui.position.top = newTop; }
function startFix(event, ui) { ui.position.left = 0; ui.position.top = 0;  var element = $(this); }
You will want this if you want to enable the element to be resizable on a scaled container.
function resizeFix(event, ui) { var changeWidth = ui.size.width - ui.originalSize.width, newWidth = ui.originalSize.width + changeWidth / percent, changeHeight = ui.size.height - ui.originalSize.height, newHeight = ui.originalSize.height + changeHeight / percent;  ui.size.width = newWidth; ui.size.height = newHeight; }
To make an element draggable, I use the following function.
$("ELEMENT").resizable({ minWidth: - ($(this).width()) * 10, minHeight: - ($(this).height()) * 10, resize: resizeFix, start: startFix });
$("ELEMENT").draggable({ cursor: "move", start: startFix, drag: dragFix }); }

A similar problem is mentioned here: jquery - css "transform:scale" affects '.offset()' of jquery
It seems the problem arises from the fact that jQuery fails to return exact size for scaled elements and therefore failing setting right offset values to the element.
To solve this, he is suggesting first setting scale to 1 and setting offset and then again resetting scale value.
But this alone does not solve the problem here. Since mouse position is taken while it is scaled, position values should also be divided by scale value.
Here is an edited version of code:
var scl = 2.5;
var
drg_h = $drag.outerHeight(),
drg_w = $drag.outerWidth(),
pos_y = $drag.offset().top/scl + drg_h - e.pageY/scl,
pos_x = $drag.offset().left/scl + drg_w - e.pageX/scl;
follow = function(e) {
var size = {
top:e.pageY/scl + pos_y - drg_h+scl*2,
left:e.pageX/scl + pos_x - drg_w+scl*2
};
$drag.parent().css("transform","scale(1)");
$drag.offset(size);
$drag.parent().css("transform","scale("+scl+")");
};
Note: I only replaced scale value for transform tag, since I am using chrome. You can also replace all instances or instead you can use a different class with 1 scale value.
JSFiddle is also here.

Here is an example of simple drag with scaling, however, in prue dom.
<style>
#dragme {
position:absolute;
border:1px solid red;
background:pink;
left:10px;
top:20px;
width:100px;
height:200px;
}
#container {
transform: scale(2,2) translate(100px,100px);
position:relative;
border:1px solid green;
background:grey;
width:200px;
height:300px;
}
</style>
<body>
<div id="container">
<div id="dragme">Hi</div>
</div>
<script>
var dragme=document.getElementById("dragme");
var container=document.getElementById("container");
dragme.onmousedown=function Drag(e){
this.ini_X = this.offsetLeft-e.clientX/2;
this.ini_Y = this.offsetTop-e.clientY/2;
container.onmousemove = move;
container.onmouseup = release;
return false;
}
function move(e){
e.target.style.left = e.clientX/2 + e.target.ini_X + 'px';
e.target.style.top = e.clientY/2 + e.target.ini_Y + 'px';
}
function release(){
container.onmousemove=container.onmouseup=null;
}
</script>
</body>

Add non-click function inside of a click function

I have the following problem. I have a .one("click") function with a variable that raises itself, and I need to add a function, that triggers, when the variable hits the wanted point. I mean, in the following code I need to use the connect function for the last 'last' img with the 'home' img, after the Result variable turns 9, which will produce a line between them, and I'll have a complete circle. Please read the code and try clicking on all img-es so that you can understand, what i need to achieve. Thanks in advance.
Here's the code:
$(document).ready(function() {
var Result = 0;
$('img').one("click", function(){
if( $('img.home').length == 0 ){
$(this).addClass('home');
}
if(Result <= 9){
var $elem2 = $('span.last');
var $elem1 = $(this).parent();
$(this).toggleClass('selected');
if ($elem2.length > 0) {
connect($elem1[0], $elem2[0], "#0F0", 5);
}
else {
$elem1.addClass('last');
}
$('span').removeClass('last');
$elem1.addClass('last');
Result++;
}
});
});
function connect(div1, div2, color, thickness) {
var off1 = getOffset(div1);
var off2 = getOffset(div2);
// bottom right
var x1 = off1.left + off1.width;
var y1 = off1.top + off1.height;
// top right
var x2 = off2.left + off2.width;
var y2 = off2.top;
// distance
var length = Math.sqrt(((x2-x1) * (x2-x1)) + ((y2-y1) * (y2-y1)));
distanz += parseInt(length);
// center
var cx = ((x1 + x2) / 2) - (length / 2);
var cy = ((y1 + y2) / 2) - (thickness / 2);
// angle
var angle = Math.atan2((y1-y2),(x1-x2))*(180/Math.PI);
// make hr
var htmlLine = "<div style='padding:0px; margin:0px; height:" + thickness + "px; background-color:" + color + "; line-height:1px; position:absolute; left:" + cx + "px; top:" + cy + "px; width:" + length + "px; -moz-transform:rotate(" + angle + "deg); -webkit-transform:rotate(" + angle + "deg); -o-transform:rotate(" + angle + "deg); -ms-transform:rotate(" + angle + "deg); transform:rotate(" + angle + "deg);' />";
htmlLine = $(htmlLine);
$('body').append(htmlLine);
return htmlLine;
}
function getOffset( el ) {
var x = 0;
var y = 0;
var w = el.offsetWidth|0;
var h = el.offsetHeight|0;
while( el && !isNaN( el.offsetLeft ) && !isNaN( el.offsetTop ) ) {
x += el.offsetLeft - el.scrollLeft;
y += el.offsetTop - el.scrollTop;
el = el.offsetParent;
}
return { top: y, left: x, width: w, height: h };
}
jsfiddle: http://jsfiddle.net/CDQhX/4/
I want to execute the connect(home and span images) after the last line is done and the Result is 9. This can't be done inside the click function, since I'm not clicking anywhere to trigger it. My knowledge don't let me work the problem around. So I appreciate any help. I'll be really glad to receive answers.

First of all, what do you mean you are not clicking anywhere and you want it executed when the last img is clicked. Can't you just check if the img is last when it is clicked, and execute what you need?
Also, on the other hand, you can try setTimeout and setInterval as described here: http://www.w3.org/TR/2011/WD-html5-20110525/timers.html
So, for example, you could do something like this:
setInterval( function() {
//do your thing
}, 500);
Which will execute the function every 500 milliseconds, so you could use that for periodic checking of your variables.

Moving an image with 360° angle in Javascript

I am trying to make an image move 360° (not rotate) back it's course, but so far I was able to move only to a specific direction, if I add left & bottom course, then the image going diagonal to left & bottom. Here are the properties:
CSS
#circle{
background:red;
border-radius:100px;
height:100px; width:100px;
position:absolute;
}
JavaSript
(function() {
var speed = 10,
moveBox = function(){
var el = document.getElementById("circle"),
left = el.offsetLeft,
moveBy = 3;
el.style.left = left + moveBy + "px";
if(left > 200){
clearTimeout(timer);
}
};
var timer = setInterval(moveBox, speed);
}());
HTML:
<div id='circle'></div>
JsFiddle Online Demo
The problem is looping back the red circle, I want it to move to left > bottom > right > up
in a circular manner.
thanks for the help.

Using Math.sin and Math.cos to describe the circle: http://jsfiddle.net/E3peq/7/
(function() {
var speed = 10,
moveX = 0.1,
moveY = 0.1,
increment = 0.1,
amp = 10,
moveBox = function(){
var el = document.getElementById("circle"),
left = el.offsetLeft,
top = el.offsetTop;
moveX += increment;
moveY += increment;
var moveXBy = Math.cos(moveX) * amp;
var moveYBy = Math.sin(moveY) * amp;
el.style.left = (left + moveXBy) + "px";
el.style.top = (top + moveYBy) + "px";
if(left > 200){
clearTimeout(timer);
}
};
var timer = setInterval(moveBox, speed);
}());
Edit: Abraham's answer in the comments is actually a lot nicer looking than this...
