in cocos2d-x, you can use "setCascadeOpacityEnabled" to synchronize the parent and children fadein and fadeout. However "setCascadeOpacityEnabled" just make the parent and children fadeout and fadein, the children's children is not set.
if you wanna the all node of a parent synchronize fadein and fadeout, you must setCascadeOpacityEnabled all node with children "true".

I've seen this discussed before, but it is usually for an animation that has 1 stop point and end point. Since the arrow in my example is bouncing https://5pshomes.artrageousdemo.com/ I am a bit confused on how this would work.
How can I add a few second delay between each iteration of the animation, while keeping the animation itself 2 seconds long?
.fl-icon-wrap{
-moz-animation: bounce 2s infinite;
-webkit-animation: bounce 2s infinite;
animation: bounce 2s infinite;
animation-delay: 2s;
}
#keyframes bounce {
0%, 20%, 50%, 80%, 100% {
transform: translateY(0);
}
40% {
transform: translateY(-30px);
}
60% {
transform: translateY(-15px);
}
}
Thanks,
When setting animation-iteration-count to infinite, the animation will repeat forever. There is no native way to increment the time between two iterations.
You can, however, increase the time in between the moment the element starts being "animated" and the effective start of the animation, by setting animation-delay property. But this delay is only applied before the first iteration, not in between consecutive iterations.
To achieve your desired result you have two methods:
modify the animation so that the delay you want is contained within the animation loop (this is the most common way to do it). With this technique, the pause is set to a percentage of the entire animation iteration so you can't decouple the speed of the animation from the time between actual element animations.
apply the animation using a class and write a small script which applies and removes that class at the appropriate times. This technique has the advantage of decoupling the duration of the animation from the time between applications and it's useful especially if the animation-iteration-count is set to 1. Also note using this technique animation-delay applies each time you apply the class, if you have set it to a valid truthy value.
Technically, there would be a third way, which would be to set the animation-play-state to running/paused, using JavaScript, at the appropriate times, similarly to the second method. But, in practice, if for any reason this goes out of sync with the actual animation, it might get to the point where it pauses the animation mid-way in the actual animation, resulting in a "buggy" behavior, from the user's perspective so option 2 above should always be preferred to this, technically possible, third method.
In this fiddle I have a small div with an opacity animation.
The animation plays correctly when the state changes to true and the component is mounted
and the div fades in.
However the animation does not play when the component is unmounted when the state goes to false.
I have the animation set as both, and I tried also applying a reverse animation (from 1 to 0) but it just ends up playing right after the first one and I end up with no square.
How can I make this fade animation play in reverse when the component disappears?
Edit:
I did not mention this is done in React.
My solution eventually was to just use a library for animation, which made this efortless.
I'm leaving the question up though in case others have vanilla solutions to the problem.
I've found sort of a hacky way to solve this. You might find something better later on, but for now, this works.
I've created a class .hide which sets opacity to 0 and visibility to hidden, which will be added to the box. The initial insertion animation is the same. But for exiting, I've applied a transition property to the box. When you click a second time, I've wrapped the setVisible() method in a setTimeout(), that has a delay timing the same as the transition duration for .hide.
This will allow the box to fade out first, and then the setVisible() method will be called.
If you don't want to use a setTimeout(), you can add an eventListener to the box for transitionend, and then call setVisible() once that is done.
Here's a fiddle: https://jsfiddle.net/32y8vjus/1/
PS: In the fiddle, I'm changing the background color to show that the transition happens before the box is removed. You can change that to opacity.
I am using a SVG image and animating the path of a diagram. It works fine. However, Once the image has been drawn I need to stop the iteration (stop from the image being redrawn). The code is found in this CODEPEN snippet attached here.
I tried removing infinite from animation in the CSS file, but the drawn image is being removed.
What I want to do is:
1.) Animate the image as shown in the code.
2.) Stop the animation from reanimating (this is because of the infinite attribute used in the animation)
3.) Once the image has been drawn, the image should remain the same unless the user refreshes the page.
Change this line:
animation: draw 10s infinite linear;
to this:
animation: draw 10s forwards;
The forwards fill mode works as follows: After the animation ends (determined by animation-iteration-count), the animation will apply the property values for the time the animation ended
Every time the animation completes its duration... It returns to its original position... How to solve that problem? I want that my element keeps the position it required after animation without using Java.
Use animation-fill-mode property
animation-fill-mode:forwards;

I've got a simple fiddle running a Tween animation using MooTools Fx.Tween and I can't seem to get the onComplete option to fire after the initial animation stops. For whatever reason, it always wants to fire in the middle. What am I doing wrong?
Fiddle
It seems you're doing it right.
I think there's a problem (basically, a 'conflict'.. you can use css transition OR js animation, not together) with -webkit-transition: all 1s linear 0 inside #bar . By commenting/removing it, it's working properly -> http://jsfiddle.net/vPuAR/
