Hi all im trying to create a loading animation with html and JQuery that looks like the windows phone 7 loading animation.
I have gotten this far
http://jsfiddle.net/b6L8M/5/
But the easing function does the opposite of what i want, i want it to go fast when its on the edges and then slow down when it comes to the center.
when looking at http://jqueryui.com/demos/effect/easing.html it does not seem that there is a built-in function for that, so how would i create that function?
If you split-up your animation into two parts you can ease-in to the center and ease-out of the center:
function moveDot(dotItem, delay) {
var dotItem = $(dotItem);
dotItem.delay(delay * 200).css('left', '0%').animate({left: '50%'}, 1000, 'easeOutCirc', function() {
dotItem.animate({left : '100%'}, 1000, 'easeInCirc', function () {
moveDot(dotItem[0], 0);
});
});
}
I also cached the $(dotItem) selection so it doesn't create a hiccup mid-animation while creating another selection (not a big chance of this happening but hey :) ).
Here is a demo: http://jsfiddle.net/b6L8M/13/
Sometimes, you have to use more than one animate function to do what you want.
I don't know how the windows phone 7 animation looks but I tried this according on what you said :
$(dotItem).delay(delay * 200).css('left', '0%').animate({left: '50%'}, 1000, 'easeOutQuart', function() {
$(this).animate({left: '100%'}, 1000, 'easeInQuart', function() {
moveDot(dotItem, 0);
});
});
The first one, easeOutQuart, is fast then slow down. The second is slow then accelrate.
I used the chaining system, but it makes the elements stop during some ms. You also can use a "delay" to do so without stop.
After fiddeling around in fiddler and using this post Help with custom jquery easing function i got it to work like i wanted
http://jsfiddle.net/b6L8M/24/ it's more or less identical to the WP7 loading!

I am creating a simple slot machine and currently using TileSprite to achieve the effects that I want - for the spinning. So far, everything works. However, after the timer stops the initial spin, I want to smoothly scroll the texture to the correct 'result' position:
R1TimerTrigger: function()
{
R1Scroll = false;
game.add.tween(SpriteReel[0].tilePosition).to( { y: R1Result }, 1000, Phaser.Easing.Bounce.Out, false);
}
There are some immediate problems, in that apparently the native tween does not recognize properties of children. Is there a way to solve this, or an alternative approach that does not use tween to achieve the result?
You code looks fine to me and the tween should work on the tile sprite as expected.
Are you starting the tween? You can start the tween automatically using 'true' as the 'autoStart' parameter
to(properties, duration, ease, autoStart, delay, repeat, yoyo)
game.add.tween(SpriteReel[0].tilePosition).to( { y: R1Result }, 1000, Phaser.Easing.Bounce.Out, true);

Okay, I'm trying to make it so when you click a button it'll spin a div with it's randomized contents and it'll slow down on stop on a specified div, now I have no idea where to start,
Here is an example of what I'm trying to do,

Any idea how to start? what should my priority be, jQuery or Javascript?
Kind Regards
EDIT: I'm not asking for anyone to spoonfeed me code, I just need an idea on where to start.
The animation itself can be probably solved easily using JQuery Animate functions. The animation supports easing, and the "ease out" is what you need. With some CSS, you would create some kind of viewport, and move the elements from right to left until the animation stops.
Let me help you with some starting code: http://jsfiddle.net/dfevruws/1/
The animation command is very simple:
$(function() {
$( "#items" ).animate({
left: -2000
}, {
duration: 5000,
easing: "easeOutQuad"
});
});
Probably more interesting than this is how you handle the selected item, but this is a different story, you ask for the Animation.
I want to instruct my user on how to interact with a part of a website with a drawn arrow and handwritten instructions. I also want it to scale up and down repeatedly in a pulsate effect with jQuery. I know there is a pulsate plugin for jQuery, but I don't know how to mix that with scale. Thanks for your responses.
As far as I know, the jQuery pulsate is for opacity only. Instead of that, I wrote a quick "pulse" function. Just animates smaller, then larger and starts again. You need to call pulse in onload.
function pulse() {
$('#arrow').animate({
height: '200px'
}, 400, function() {
// First animate complete
$('#arrow').animate({
height: '150px'
}, 400, function() {
// Second animate complete
pulse();
});
});
}

There may be a better way, and of course you probably need to clean up the css to make it point where you want, etc.
I want to move a div down a page, and I want it to slow down as it reaches the target.
I tried using call back with recursive func but it doesn’t look smooth:
function MovePanel() {
sidePanel.animate({
"marginTop": newCurrTop
}, moveSpeed, function () {
MovePanel();
});
}
Is it possible to slow down an JQuery animation?
If not what are the alternatives?
Thanks.
The animate method takes a 3rd param called "easing"; learn about it here:
http://api.jquery.com/animate/

Easing can really bring life to an
effect. Easing controls how an
animation progresses over time by
manipulating its acceleration.
Very basic question. I have a very simple web design utilizing a png with transparency, overlaying another base image. The idea here is that it cycles visibility continously, fading in quickly, displaying for a longer interval, fading out quickly, and remaining invisible for an equal longer interval, basically replicating the behavior of an animated GIF from back in the day. The png starts with display set to none.
My problem is jQuery doesn't seem to have a "pause" or "delay" event handler to help here. There are numerous plugins filling the gap, but I'd rather not include one if there's a simple way that I'm missing. That might require falling back on setInterval or setTimeOut, but I'm uncertain of the syntax to do that.
What I want schematically is something like:
--loop start--
$("#pngOverlay").fadeIn(1000);
(5000 delay) // using setTimeout or setInterval if jQuery method unavailable
$("#pngOverlay").fadeOut(1000);
(5000 delay)
--loop repeat--
The following does the behavior once, so I guess if this could be wrapped in a loop it might work, but it doesn't strike me as elegant or the right way.
setTimeout(function() {
$("#pngOverlay").fadeIn(1000);
}, 5000);
setTimeout(function() {
$("#pngOverlay").fadeOut(1000);
}, 10000);
Thanks for any suggestions. I would just use GIFs, but need the transparency for this. (In the old days, we used animated GIFs and we liked them...)
<script language="JavaScript" type="text/javascript">
function showimage(){
$("#pngOverlay").fadeIn(1000);
setTimeout('hideimage()',5000);
}
function hideimage(){
$("#pngOverlay").fadeOut(1000);
setTimeout('showimage()',5000);
}
$(document).ready(function() {
showimage();
});
</script>
Something like this?
setInterval(function()
{
var elm = $('#pngOverlay');
if (elm.is(':hidden'))
elm.fadeIn(1000);
else
elm.fadeOut(1000);
}, 5000);
How about using an animated PNG?
One trick I have seen is to have jQuery carry out an animation for 5000 milliseconds that has no visible effect.
$("#pngOverlay").animate({opacity:1}, 5000);
If the opacity of the item was 1 to start with then it does not have a visible effect but it does pause for 5 seconds.
