Animation 如何在运行动画序列时添加副作用?

Animation 如何在运行动画序列时添加副作用?,animation,react-native,Animation,React Native,我试图建立一个倒计时计时器,并为每一个计数我想播放一个声音。动画效果很好,但我想知道在序列中运行动画时是否可以播放声音 代码: Animated.sequence([ Animated.timing(this.state.moveY3, { toValue: 50, duration: 1000, useNativeDrive: true,

我试图建立一个倒计时计时器,并为每一个计数我想播放一个声音。动画效果很好,但我想知道在序列中运行动画时是否可以播放声音

代码:

Animated.sequence([

            Animated.timing(this.state.moveY3,  {
                toValue: 50,
                duration: 1000,
                useNativeDrive: true,
                easing: Easing.spring
            }),  // play sound

            Animated.timing(this.state.moveY3,  {
                toValue: 100,
                duration: 100,
                useNativeDrive: true,
            }),

            Animated.timing(this.state.moveY2,  {
                toValue: 50,
                duration: 1000,
                useNativeDrive: true,
                easing: Easing.spring
            }), //play sound

            Animated.timing(this.state.moveY2,  {
                toValue: 100,
                duration: 500,
                useNativeDrive: true,
            }),

            Animated.timing(this.state.moveY1,  {
                toValue: 50,
                duration: 1000,
                useNativeDrive: true,
                easing: Easing.spring
            }), // play sound

            Animated.timing(this.state.moveY1,  {
                toValue: 100,
                duration: 500,
                useNativeDrive: true,
            }),


]).start()
注意:我知道如何播放声音,我使用react native sound软件包,我只是对如何在每次计数时播放声音感到困惑。

进入每个动画的
start()
方法。 因此,您可以将动画分解为更小的部分,而不是按
顺序编写所有动画,如下所示:

// Run animation

animation1.start(() => {
    playSound1();
    Animated.sequence([
        animation2,
        animation3,
    ]).start(() => {
        playSound2();
        Animated.sequence([
            animation4,
            animation5,
        ]).start(() => {
            playSound3();
            animation6.start();
        })
    })
});

// Move animations into variables so that the execution of the animation is more readable

const animation1 = Animated.timing(this.state.moveY3,  {
    toValue: 50,
    duration: 1000,
    useNativeDrive: true,
    easing: Easing.spring
});

const animation2 = Animated.timing(this.state.moveY3,  {
    toValue: 100,
    duration: 100,
    useNativeDrive: true,
}),

const animation3 = Animated.timing(this.state.moveY2,  {
    toValue: 50,
    duration: 1000,
    useNativeDrive: true,
    easing: Easing.spring
}),

...

通过将第一位中的一些内容移动到其他函数中,您可以稍微减少嵌套并使其更具可读性。。但它应该是这样工作的。

回答得很好
