This is a game that I am building and in this game I have created some levels. But when the game ends for the first time the second time my countdown timer is not getting decremented.
this is my App.js component:
import "./App.css";
import React, { useState, useEffect, useCallback } from "react";
import SingleCard from "./components/singleCard/SingleCard";
import Timer from "./components/timer/Timer";
import Modal from "./components/modal/Modal";

{ src: "/img/img-4.png", matched: false },
{ src: "/img/img-5.png", matched: false },
{ src: "/img/img-6.png", matched: false },
];

const onGameEnd = useCallback(() => {

}, [isgameEnd]);
useEffect(() => {
setTimeout(() => {
setLoading(false);
}, 4000);
}, []);

export default App;
and this is my timer component:
import React, { useEffect, useState } from "react";
import "./Timer.css";
const Child = ({ timerStart, timer, onGameEnd, restartTimer }) => {
const [seconds, setSeconds] = useState(40);
// let time = 40;
useEffect(() => {
if (restartTimer === true) {
setSeconds(40);
}
}, [seconds, restartTimer]);
// console.log("restart Timer", restartTimer);
useEffect(() => {
if (timerStart === true) {
timer = setInterval(() => {
if (seconds > 0) {
setSeconds(seconds - 1);
}
if (seconds === 0) {
onGameEnd(true);
clearInterval(timer);
}
}, 1000);
}
return () => clearInterval(timer);
});
return (
<p className="time">
Time{" "}
<span className="span1">
<span>{seconds}s</span>
</span>
</p>
);
};
const Timer = React.memo(({ timerStart, timer, onGameEnd, restartTimer }) => (
<Child
timerStart={timerStart}
timer={timer}
onGameEnd={onGameEnd}
restartTimer={restartTimer}
/>
));
export default Timer;
my timer gets re initialized when restartTimer state is set to true.
