How to use commands only when a current command is triggered?

This question might be complicated and my brain can't really explain it well so please bare with this crappy explanation, My question, When you trigger a command for example .start it will start let's say a text based game, of course you would have the commands to be able to actually play the game however my concern is people can still trigger the ingame commands without needing to start the game for example .

if message.content.startswith("/play"): #Here is the play command where you execute the game to start
await client.send_message(message.channel, "Welcome to the game!")
if message.content.startswith("/examine):
await client.send_message(message.channel, "You examined the rock and well, got a rock!") #In-Game commands/movements


What i'm saying is, is there a way of only being able to use the in-game commands only when the game itself is activated?
Additional Question: How would you store a user's information like basically saving the game (You don't really need to answer this as i would like to learn this myself but any tips would be great!)

First, we want some object that stores the state of a particular session. We can just call this object Game. We'll maintain a mapping of discord.Users to Games. A User existing in this mapping means that they are playing the game. Some basics would look something like:

Game

discord.User

Game

User

from discord.ext import commands

class Game:
def __init__(self):
self.points = 0
self.inventory =

bot = commands.Bot('/')

sessions = {}

@bot.command(pass_context=True)
async def play(ctx):
if ctx.message.author.id in sessions:
await bot.say("You're already playing")
return
sessions[ctx.message.author.id] = Game()
await bot.say("Welcome to the game!")

@bot.command(pass_context=True)
async def quit(ctx):
if ctx.message.author.id not in sessions:
await bot.say("You're not playing the game")
return
del sessions[ctx.message.author.id]
await bot.say("Game Over")

@bot.command(pass_context=True)
async def examine(ctx):
session = sessions.get(ctx.message.author.id, None)
if session is None:
await bot.say("You're not playing the game")
return
session.inventory.append("A rock")
await bot.say("You examined the rock and well, got a rock!")

bot.run("TOKEN")


Some things you could do to extend this: make use of checks and CommandErrors to avoid having to repeat the code for checking sessions; make sure that Games are pickleable, and write code for saving games using pickle; write a game that's more fun than collecting rocks.

check

CommandError

Game

class Game: def __init__(self): self.points = 0 self.inventory = sessions = {} @bot.command(pass_context=True) async def test(ctx): if ctx.message.author.id in sessions: await bot.say("oof") return sessions[ctx.message.author.id] = Game() await bot.say("oof 2")
