animation

问题 I'm learning React native and I would like to have heart beat animation I did that but it's not the good result, I would like to have heart beat. If someone can help me it's would be very nice thanks a lot import React, { PureComponent } from "react"; import { Animated, StyleSheet, Text, View } from "react-native"; export class Loading extends PureComponent { constructor(props: any) { super(props); this.state = { opacity: new Animated.Value(0), }; } public componentDidMount() { Animated

问题 I want to know how can you edit/modify the css so that it starts the animation when the user scrolls at the page where the whole animation or the skills bar in my case, is visible. The animation works but the problem I am facing is that it works on the load of the website, and when I get to the skills bar the animation has been already played and it is not there anymore. See the example below: https://drive.google.com/file/d/1ogZE87xoeJV4vbMkE7fBV068ERMzd8it/view This is an example, see how

问题 Apologies in advance for any tacky code (I'm still learning Swift and SwiftUI). I have a project where I'd like to have multiple timers in an Array count down to zero, one at a time. When the user clicks start, the first timer in the Array counts down and finishes, and a completion handler is called which shifts the array to the left with removeFirst() and starts the next timer (now the first timer in the list) and does this until all timers are done. I also have a custom Shape called

问题 I have a Row Widget that holds a child Widget in one of its cells (the others hold a Spacer() ). Depending on the state, the cell which holds the child changes, resulting in a position change of the child Widget. I want to animate this motion to make it smooth. Is there a way of doing so with the standard animation Widgets (something like AnimatedPositioned , which won't work in this case)? 回答1: You could use AnimatedPositioned if you insert a Stack inside your row. Otherwise, you can use an

问题 This is the code where I use Animated.text only here. It was working but when I installed react-native-render-html library after that this error comes. However, I have uninstalled that library but still this error comes. return ( <View style={styles.tabBar}> {props.navigationState.routes.map((route, i) => { const color = Animated.color( Animated.round( Animated.interpolate(props.position, { inputRange, outputRange: inputRange.map(inputIndex => inputIndex === i ? 255 : 0 ), }) ), 0, 0 );

问题 I’m trying to animate a Mayavi pipeline volume: src = mlab.pipeline.volume(mlab.pipeline.scalar_field(data),vmin=.1*np.max(data),vmax=.2*np.max(data)) that is combined in the pipeline by another dataset represented as a cut plane. However, I can’t get the volume visualization to update - only the first frame shows up. The animation is stepping through the data correctly (I get different values of the np.max(data[t]) below) but nothing in the visualization changes. My understanding is that
