使用动画API在Vega中创建动画

import React, {useState, useRef} from 'react';  // 在此处次添加useRef
import {
  StyleSheet, 
  Text, 
  ImageBackground, 
  View, 
  Image,
  Animated  // 在此处添加Animated
} from 'react-native';
import {Link} from './components/Link';

export const App = () => {
  const [image, setImage] = useState(images.vega);
  
  // 添加此行：
  const position = useRef(new Animated.ValueXY({x: 0, y: 0})).current;

  const styles = getStyles();
  // ... 组件的其余部分

const getRandomNumber = (min: number, max: number) => {
  return Math.random() * (max - min) + min;
};

const handleImagePress = () => {
  const randomX = getRandomNumber(-100, 100);
  const randomY = getRandomNumber(-100, 100);

  Animated.timing(position, {
    toValue: {x: randomX, y: randomY},
    duration: 1000,
    useNativeDriver: false,
  }).start();
};

<View style={styles.image}>
  <Image source={image} />
</View>

<Animated.View style={[styles.image, position.getLayout()]}>
  <Image source={image} />
</Animated.View>

import {
  StyleSheet, 
  Text, 
  ImageBackground, 
  View, 
  Image,
  Animated,
  TouchableOpacity  // 添加此项
} from 'react-native';

<Animated.View style={[styles.image, position.getLayout()]}>
  <TouchableOpacity onPress={handleImagePress}>
    <Image source={image} />
  </TouchableOpacity>
</Animated.View>

npm install && npx react-native build-vega
