## Advanced Example



Play it live on expo → https://snack.expo.dev/@atlanteh/react-native-slot-machine



```

import {useState, useEffect, useRef} from 'react';

import { Text, View } from 'react-native';

import SlotMachine from 'react-native-slot-machine';



export default function App () {

    const [slotSettings, setSlotSettings] = useState({duration: 4000, slot1: 1234, slot2: 'hello', slot3: '2351'});

    const slotRef = useRef(null);

    useEffect(() => {

      setTimeout(() => setSlotSettings({duration: 1000, slot1: '4321', slot2: 'world', slot3: '1234'}), 5000);

      setTimeout(() => setSlotSettings({duration: 4000, slot1: '1234', slot2: 'hello', slot3: '2351'}), 7000);

      setTimeout(() => slotRef.current.spinTo('prize'), 12000);

    }, []);



    const symbols = ['🍏', '🍎', '🍐', '🍊', '🍋', '🍌']; // can't use emojies in SlotMachine because some of them are comprised of 2 chars

    return (

        

            

                

                

                 {symbols[c]}} duration={slotSettings.duration} />

            

        

    );
