easing

问题 I have an element that I am using jquery/css3 to rotate on scroll. The trouble is that it is kinda jumpy when you scroll, and it stops immediately when you stop. I would love for it to be more of a smooth playing rotation that starts when you start scrolling and then eases to a stop after you stop scrolling, rather then just rotating a set # of degrees each time the scroll wheel moves. My code and link is below: http://pollenbrands.com/rjj/ (scroll down to 100% fruit) var angle = 1; jQuery

问题 I am trying to understand this easing formula: float easeInOutSine(float t, float b, float c, float d) { return -c/2 * (cos(M_PI*t/d) - 1) + b; }; Here are what the variables equal: t: current time b: start value c: change in value d: duration I am trying to apply this to a sprite transformation and am confused about what exactly needs to be passed in. If I wanted for instance to move a ball from y = 0 towards y = 10 at 0.25 units per second, which values are which? What I am really looking

问题 I am working with some css animation. But I found that, the CSS transition only support following easing function. ease | linear | ease-in | ease-out | ease-in-out | cubic-bezier() I do want to use something like easeOutBack easing in the animation with pure css. I am thinking to do it with the webkit-animation. But only safari support it. The easeOutBack motion is a motion where the object will go beyond the boundary and back again.More about different motion function. You can see this link

问题 Here is my code thus far: $('.my_button').click(function() { $.scrollTo( '#my_anchor', 1200, {easing:'easeInOutExpo'}, function() { // function not working here }); }); The callback function worked previously, but since I changed to the scrollTo method with easing, it doesn't any more! Just to make it clear I only need to know how to get my callback function working again, everything else is fine. 回答1: There is no forth parameter, but the third parameter (settings) accepts an onAfter callback

问题 I'm drawing a non-traditional ring-clock in canvas. The time is represented by a second ring, second hand, minute ring, and hour ring. I am using webkit/mozRequestAnimationFrame to draw at the appropriate time. I would like to modify the second ring to animate to the next second quickly (125ms - 250ms) and with Quadratic easing (instead of that dreaded snap). Much like the Raphael JS Clock animates its second ring, except it uses different easing: http://raphaeljs.com/polar-clock.html JS

问题 Please take a look at this fiddle: http://jsfiddle.net/dhcyA/ Try clicking on a block. What I want is that when the other elements disapear, the selected block will animate/ease to his giving position instead of just jumping like it does now. Then the same animation repeats itself when clicking again on the box, but then back to place. Maybe to keep in mind: I'm using a reponsive design, which means those blocks can be vertical and horizontal after scaling the window. Any redevisions on the

问题 I've got a link, when clicking this I want a div to slideIn with easing, and then clicking the link again, it should close the div, with easing... I've looked at jQuery easing plugin, but it doesn't work with jQuery 1.5.1? Any ideas to what I can do, and how? Right now I only got a slideToggle function, which doesn't have easing? $('.open-mypage').click(function () { $('#mypage-info').slideToggle('2000', function () { // Animation complete. }); }); 回答1: jQuery slideToggle() documentation says

问题 I like to create a smooth slowing scroll effect after panning an image in a scrollbox. Just like panning the map in maps.google.com. I'm not sure what type it is, but exactly same behaviour: when dragging the map around with a fast move, it doesn't stop immediately when you release the mouse, but it starts slowing down. Any ideas, components, links or samples? 回答1: The idea: As per your comment, it should feel like Google Maps and thus while dragging the image, the image should stick to the

问题 In the following use case, I'm trying to animate the lineWidth of an SKShapeNode . SKEase is part of the wonderful SpriteKitEasing github repo from Craig Grummitt. One of its facilities is a Float changing ease action that appears to change the value of a float over time. However I can't figure out how to use it. Xcode gives the following suggestions when typing it in: let lineWeight = SKEase.createFloatTween(<start: CGFloat, end: CGFloat, time: TimeInterval, easingFunction: AHEasingFunction,

问题 Im getting an error when i add the jquery easing 1.3 plugin to my page, i havent even used custom easing yet but just loading it stops animated elements working. Im not a jquery expert so i dont really know how to debug it but im fairly sure that there is a conflict, heres the error: Uncaught TypeError: Property 'undefined' of object #<Object> is not a function The error is triggered when you roll over the animated elements, heres the page im working on: http://www.pegbarandgrill.com/blog/ if
