I'm trying to figure out the logic using React.useState hooks. Basically I want to alternate the "volume" option under the "PlayOn" object's state from 0 to 0.75. I'm by no means a react expert.
I just need the logic of the function to put in soundChange to alternate between the two states: 0, which is the default initial state in which the switch component has not been pressed; 0.75 which is its final state in which the switch component has been pressed, and back to 0 again when the switch gets pressed again. I hope you guys could help me out.
import React from 'react';
import { makeStyles } from '@material-ui/core/styles';
import Switch from '@material-ui/core/Switch';
import Fade from '@material-ui/core/Fade';
import FormControlLabel from '@material-ui/core/FormControlLabel';
import Typography from '@material-ui/core/Typography';
import Paper from '@material-ui/core/Paper';
import useSound from 'use-sound';
import Rick from './sounds/rick_astley.mp3';
function Myswitch() {
const classes = useStyles();
const [checked, setChecked] = React.useState(false);
const [withSound, setSound] = React.useState(0);
const [playOn] = useSound(Rick, {
volume: withSound,
interrupt: true,
soundEnabled: true,
});
const soundChange = () => {
setSound(/*LOGIC HERE TO ALTERNATE BETWEEN 0 and 0.75 states*/);
};
const handleChange = () => {
setChecked((prev) => !prev);
};
return (
<div className={classes.root}>
<FormControlLabel
control={
<Switch
checked={checked}
onChange={handleChange}
onMouseDown={soundChange}
/>
}
label={
<Typography variant='h5' color='secondary'>
'DO NOT click!'
</Typography>
}
/>
<div className={classes.container}>
<Fade in={checked}>
<Paper elevation={1} className={classes.paper}>
<img

}
alt='Never gonna give you up'
/>
<Typography variant='h5' color='secondary'>
You had to click it XD
</Typography>
</Paper>
</Fade>
</div>
</div>
);
}
export default Myswitch;
As far as I understand your question you want to toggle between states. What you can do is that have a state variable containing initial
and final
states and then toggle using if...else
in the soundChange()
function shown below.

Code Snippet
import React, { useState } from "react";
export default function App() {
const [states] = useState({
initial: 'initial',
initialState: 0,
final: 'final',
finalState: 0.75
})
const [withSound, setSound] = useState(states.initialState);
const [current, setCurrent] = useState(states.initial);
const soundChange = () => {
if (withSound === states.initialState) {
setSound(states.finalState)
setCurrent(states.final)
} else {
setSound(states.initialState)
setCurrent(states.initial)
}
}
return (
<div>
<button onClick={() => soundChange()}>Play {withSound} </button>
<div> { current } </div>
</div>
)
}
This will surely give you an idea about how to approach the problem.
First do this:
const soundChange = () => {
setSound(!withSound);
};
Then
[playOn] =useSound(Rick, {
volume: withSound ? 0.75 : 0,
interrupt: true,
soundEnabled: true,
});
So in your desired event calls, call playOn()
First set your withSound to null by default
const [withSound, setSound] = React.useState(null);
Then implement your your function as
const soundChange = () => {
setSound(!withSound);
};
