I am trying to make a game in react-native. I want to render 200+ views on the Game screen. Each View has a pressable functionality. Whenever I press the View I need to run a function that will change the View background color and update score on the game context. But Whenever I try to press any View it took some time to change the background and update the context.
Note
I am using the expo as a development environment and I am using a real device too.
My View Component
import { useEffect, useState, memo } from "react";
import { useContext } from "react";
import { gameContext } from "./gameContext";
import { Pressable, View } from "react-native";
function CheckBoxCom() {
const [active, setActive] = useState(false);
const { score, setScore } = useContext(gameContext);
useEffect(() => {
let time = setTimeout(() => {
setActive(false);
}, Math.floor(Math.random() * 35000));
return () => clearTimeout(time);
}, [active]);
const handlePress = () => {
if (active) return;
setActive(true);
setScore(score + 1);
};
return (
<View>
<Pressable onPress={handlePress}>
<View
style={{
width: 20,
height: 20,
borderWidth: 2,
borderColor: active ? "green" : "gray",
margin: 3,
borderRadius: 3,
backgroundColor: active ? "green" : null,
}}
></View>
</Pressable>
</View>
);
}
export default memo(CheckBoxCom);
Game Screen Component
import { useContext, useEffect, useState } from "react";
import { StatusBar } from "expo-status-bar";
import { StyleSheet, Text, View, FlatList } from "react-native";
import CheckBox from "./CheckBox";
import { gameContext } from "./gameContext";
export default function Game({ navigation }) {
const { score, time, setTime, boxList } = useContext(gameContext);
const [intervalId, setIntervalId] = useState("");
useEffect(() => {
const int = setInterval(() => {
setTime((prvTime) => prvTime - 1);
}, 1000);
setIntervalId(int);
return () => clearInterval(int);
}, []);
if (time === 0) {
clearInterval(intervalId);
navigation.navigate("Score", { score });
}
return (
<View style={{ flex: 1 }}>
<StatusBar style="auto" />
<View style={styles.textHeader}>
<Text>Score : {score}</Text>
<Text>Time Left: {time}s</Text>
</View>
<View style={styles.checkBoxContainer}>
<FlatList
style={{ alignSelf: "center" }}
data={boxList}
initialNumToRender={50}
numColumns={12}
renderItem={(i) => <CheckBox />}
keyExtractor={(i) => i.toString()}
scrollEnabled={false}
/>
</View>
</View>
);
}
const styles = StyleSheet.create({
textHeader: {
display: "flex",
flexDirection: "row",
justifyContent: "space-between",
width: "100%",
marginTop: 40,
paddingHorizontal: 30,
},
checkBoxContainer: {
margin: 20,
display: "flex",
flexWrap: "wrap",
height: "80%",
overflow: "hidden",
flexDirection: "row",
},
});
How can I run view function immediately whenever I press it?
