react-flying-objects
A lightweight React package to make your object/s fly :)
DEPENDENCIES
npm install --save react-native-web
INSTALLATION
npm install --save react-flying-objects
PURPOSE
The main point of that library is to animate whatever you want, in a whatever direction and speed by using specific easing. You can also use a delay. And all of that stuff should be run in the web browser. We have many great libraries that give that opportunity, but the reason I wrote that lib was to create animations really fast and in the most intuitive way as for the frontend programmer.
HOW IT WORKS?
You have to think about like an html container, where css is the ruler. We can assume we have so many anmimations as we can imagine.
In this library I use most common function of React Native lib which is Animated.timing(). As you can see there, you can use all those props including the one I added in my package called fromValue. Which means "the point" we start.
All the keys of objectConfig should be a valid names of the React Native styles. So called "React" camelCased styles .
In my demo I show you one of my example input objectConfig. If you'd have your own great examples, please share them by commiting in the examples section.
WORKING EXAMPLE USING emoji-mart
import { useMemo, useState } from 'react'
import { Easing } from 'react-native-web'
import { Emoji, Picker } from 'emoji-mart'
import Fly from 'react-flying-objects'
import 'emoji-mart/css/emoji-mart.css'
const DELAY = 1000
const DURATION = 5000
const SIZE = 25
const random = (min, max) => Math.floor(Math.random() * (max - min) + min)
const App = () => {
const [animatedEmoji, setAnimatedEmoji] = useState() // To randomly set values in the objectConfig
const [flyingObjects, setFlyingObjects] = useState([]) // Used to manage all flying currently objects by the Fly component
const onSelect = emojiData => {
const emoji = <Emoji emoji={emojiData} size={SIZE} />
setAnimatedEmoji(emoji) // Setting the object which would fly in a moment
}
const objectConfig = useMemo(() => ({ // Config for a single flying object which would fly in a moment
right: {

toValue: 800,

}
}), [animatedEmoji]) // On animatedEmoji change we calculate new random values for the next flying object
return (

/>
<Picker set='apple' onSelect={onSelect} />
</div>
