What can I do inside CompositionTarget.Rendering?

由 本秂侑毒 提交于 2021-02-20 17:51:48
问题 The CompositionTarget.Rendering event is the perfect thing to build a game's main loop upon. It basically fires at the rate of vsync (usually 60 Hz). Occurs just before the objects in the composition tree are rendered. The Rendering event is routed to the specified event handler after animation and layout have been applied to the composition tree. The per-frame animation how-to article explains a little bit more. Note that your event handler method is called after layout has been computed.

问题 I am facing a problem that I've tried to solve in lots of different ways, but I cannot get it to work. Please see this Expo application, I've created a dumb example that demonstrates my problem: https://snack.expo.io/HJB0sE4jS To summarize, I want to build an app with a draggable component (The blue dot in the example), but while the user drags the component I also need to update the state of the app (the counter in the example). The problem is that whenever the state updates during dragging,

iOS - How to fade in a UIView with a horizontal swipe/fade?

由 余生颓废 提交于 2021-02-20 02:26:52
问题 Is there a way in iOS to run a fade animation on a UIView (UILabel specifically) that will fade in with a swipe action (so if it paused half way, the left side is visible, right side invisible and middle some gradient between). I'm wondering if theres a Gradient mask I could use with the Alpha channel? Any ideas or code snippets for achieving this sort of reveal? Vertical or Horizontal. (Link to the same question but for Android for reference - Android - How to fade in a View with a

问题 I've tried to do an animated dashed line in HTML (SVG) / CSS / JS. This is my first svg animation... and clearly... I don't understand anything. First of all, this is my dashed line : <svg id="bf7de8ba-cf75-48ab-a36c-06f8d86635d5" data-name="Calque 1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" viewBox="0 0 690.814 824.302"> <defs> <style> .a00cb6af-c716-4d00-9962-797e598003da, .a6fde9f6-9a2f-4715-ac34-678948a4d015, .b963f74d-80cb-4571-80bd-9cf5cd28cce2 {

CSS Animation Fade In pause… Fade Out

由 耗尽温柔 提交于 2021-02-19 04:05:00
问题 I’m trying to get some (will be images) blocks to fade in pause for a few seconds and then fade out.... I’ve got it so far but it doesn’t seem to want to stay faded out and i’m unsure where i’m going wrong. After its faded out it then shows up again. I have a fiddle which shows it very basicly. /* Defines the animation keyframes */ @-webkit-keyframes fadein { 0% { opacity: 0; } 72% { opacity: 0; } 100% { opacity: 1; } } @-moz-keyframes fadein { 0% { opacity: 0; } 72% { opacity: 0; } 100% {

由 喜夏-厌秋 提交于 2021-02-18 18:23:51
问题 I have a sequence of events that I am trying to create using jQuery but I am failing miserably. I have a number of lists with a number of list items in each list. The list of events I am trying to achieve is as follows: Fade in list 1 > Animate List 1 item 1 > Animate List 1 item 2 etc... Fade out list 1 Fade in list 2 > Animate List 2 item 1 > Animate List 2 item 2 etc... Fade out list 2 etc... This would then loop over and over.
