Discord.js Bot Replying to All Commands - discord

Question

I am using discord.js to create a "text-adventure" bot. The user chooses what they would like to do by replying a, b, c, or d. I have separated the questions by using a variable called "stage". The problem is, the bot does not let the user choose the next choice, but instead uses their previous answer.
I tried using .lastMessage, but I either couldn't get it to work. That or I had been using it wrong, as I am a bit of an amateur.
Below is a bit of code to show you how I handled it. (I removed the story as it got a bit...violent)
require("dotenv").config();
var stage = 0;
let time = 0;
const { Client } = require('discord.js');
const client = new Client();
client.on('ready', () => {
console.log(`${client.user.username} has arrived`);
});
client.on('message', (message) => {
if (message.author.bot === true) return;
if (message.content === 'begin') {
}
if (message.content === 'restart'){
stage = 0;
message.channel.send('Welcome adventurer! To begin, type "a"');
}
if (message.content === 'a' && stage === 0) {
message.channel.send('...');
message.channel.send('...');
message.channel.send('...');
message.channel.send('Do you:');
message.channel.send('a) ...');
message.channel.send('b) ...');
message.channel.send('c) ...');
message.channel.send('d) ...');
stage = 1;
}
if (message.content === 'a' && stage === 1) {
message.channel.send('...');
message.channel.send('...);
message.channel.send('...');
message.channel.send('...');
message.channel.send('...');
message.channel.send('Do you:');
message.channel.send('a) ...');
message.channel.send('b) ...');
}
});
client.login(process.env.DISCORDJS_BOT_TOKEN);
EDIT: Sorry I didn't add that much code, I am unfamiliar with this website, and added the rest. The bot itself works, I'm just not sure how to make it only respond to one message once.
I used this video if you need more info:

At the end of your first message.content check block, your code sets stage = 1;. Then it immediately evaluates the next message.content && stage check as true, because you just set stage to 1. Try:
} else if (message.content === 'a' && stage === 1) {
or use a switch/case statement. You could also return; right after stage = 1;. Here is a simplified example:
var stage = 0;
function client_on(message) {
if (message.content === 'a' && stage === 0) {
//...
console.log(stage,message.content);
stage = 1;
//Return here, or else the next block will evaluate to true
return;
}
if (message.content === 'a' && stage === 1) {
//...
console.log(stage,message.content);
stage = 2;
//Return here also, if you have more checks to run
return;
}
}
client_on({content:'a'});
console.log('next message');
client_on({content:'a'});
Also, your entire code logic could just be represented as a data structure like:
var storyMap = new Map([
['0restart', 'Welcome adventurer! To begin, type "a"'],
['1a', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['1b', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['1c', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['1d', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['2a', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['2b', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['2c', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
['2d', '...\nDo you:\na)...\nb)...\nc)...\nd)...'],
]);
client.on('message', (message) => {
var key = stage.toString() + message.content;
var response = storyMap.get(key);
if (response) {
message.channel.send(response);
stage++;
} else {
message.channel.send('error, try again');
}
}
