Error404_PureAnimation | simple animation in pure css | Animation library

I'm trying to get two views to move to the middle of the screen and bounce back again x number of times.

This code does that but it runs only once. ` val view = findViewById(R.id.imageView2)

I try to get a button that has this cool effect of the border radius changing when tapped (like in the Android 12 default calculator application) while also keeping the button's ripple effect.

What I thought would work was this:

I have an animated SVG where each starts after its previous . The first starts on click or 0s.
I have a problem with stopping the animation (without JS, only in XML). I press click, the animation starts. Before the entire animation ends I press click and trigger a new animation. However the previous animation continues to run and it messes up all s starting from 2.
I have tried different options (begin with time offsets; begin with id.end), but I haven't found a solution. Maybe someone who is more experiences with SVG than me could help me?

Here is my SVG:

So, straight to the problem:

I've created a custom UIViewControllerTransitioningDelegate that I use to animate a view from one view controller, to full-screen in another view controller. Im doing this by creating UIViewControllerAnimatedTransitioning-objects that animate the presented view's frame. And it works great! Except when I try to adjust the additionalSafeAreaInsets of the view controller owning the view during dismissal...

It looks like this property is not accounted for when I'm trying to animate the dismissal of the view controller and its view. It works fine during presentation.

The gif below shows how it looks. The red box is the safe area (plus some padding) of the presented view - which I'm trying to compensate for during animation, using the additionalSafeAreaInsets property of the view controller owning the view.

As the gif shows, the safe area is properly adjusted during presentation but not during dismissal.

So, what I want is: use additionalSafeAreaInsets to diminish the effect of the safe area during animation, by setting additionalSafeAreaInsets to the "inverted" values of the safe area. So that the effective safe area starts at 0 and "animates" to the expected value during presentation, and starts at expected value and "animates" to 0 during dismissal. (I'm quoting "animates", since its actually the view's frame that is animated. But UIKit/Auto Layout use these properties when calculating the frames)

Any thoughts on how to battle this issue is great welcome!

The code for the custom UIViewControllerTransitioningDelegate is provided below.

I am trying to have an enemy attack the player and the enemy attacks through animation however the method I have to prevent the animation from starting when others are active are not working. The problem should be shown by this (might be low quality). As you can see the problem is that it is turning the bools on and off continuously. I don't know why this is happening because the way I have it should work. Is there a way to block them from doing this and run one at a time that works? Here is my code:

Edit: I forgot to say this but I am not getting any errors with my code

I made the following PulsatingView:

Currently, using the latest version of Vue.js in my Laravel application. The expected result is when the user click on a button, it will show a certain div with the page content, and it will show a fade up animation. Specifically, what I want it to do, is when a button is clicked, the page will show and a fade-up animation will show every time I switch between pages.

The problem

I'll use the example below to simplify my problem. When the user clicks on the button with the @click='productsPageBtn' it shows the animation. When I click on the dashboard (the default) @click='dashboardPageBtn' it does not show the animation. But when I click back on the productsPageBtn is does work again and shows the animation again.

They both work in the same way, with a v-if and a :class when the button is clicked, it will add the animation class. The dashboard animation does show when it's loaded first on the page, but does not show the animation when I click from products to dashboard.

How am I able to fix this so that when I click on dashboard, it will also show the animation instead of just products?

Thank you in advance for any help.

I am trying to animate a gaussian modulated wave pulse using matplotlib in Jupyter Lab, but I cannot get it to work. I want the pulse to move forwards in time, i.e move from the middle towards the right (in other words, show the pulse propagation).

I create the pulse itself by using scipy's "signal.gausspulse" function which creates a static image of the pulse. I then create a meshgrid and try to "map" the pulse onto it while looping it through the animate function that takes in frame number "i" as input and loops through the values that we want to animate.

Before I got the pulse moving in the animation, it was just static without any movement. I figured that it was because the entire array with y-values for the wave pulse was not changing with time, so I tried creating a loop for updating it. This helped, but it is very slow and makes the pulse move upwards twice, and then stops the motion completely.

I cannot figure this out and genuinely do not know what to do so any help would be greatly appreciated! :) I might be misusing some of the terminology so I apologise for that in advance - I tried commenting the code and explaining the steps that I go through so hopefully it helps a bit.

This might be a strange question. We get the animation for free in a UIStackView when we show or hide a view inside it. But this behaviour is conflicting with another animation that I have. So is there a way to disable the default animations for UIStackView?

I want it to just show or hide the child view without any animation. How do I achieve this with swift?

updated

So if I do a view2.isHidden = true, the StackView will hide the View2 with a collapse animation by default. I want it to just force hide without the animation
