2.4. A textadventure game as a telegram chatbot

This is an example of a chatbot on telegram that acts as an adventure game.

Suppose you have all your custom stuff defined in mystuff.py.

from mystuff import rooms, items, monsters, MyPlayer, MyWorld, MyParser

from telegram.ext import Updater, CommandHandler, MessageHandler, Filters

class Game:

     def __init__(self):

         world = MyWorld(rooms=rooms, items=items, monsters=monsters)
         player = MyPlayer(world, world.room("start"))

         self.parser = MyParser(player)

     def play(self, command):
         return self.parser.understand(command.lower())


class GameBot:

    def __init__(self):
        # save games with all players
        self.games = {}

    def start(self, bot, update):
        # start a new game
        self.games[update.message.chat_id] = Game()

    def respond(self, bot, update):
        # get the game with this player
        game = self.games[chat_id]
        # give the player's message as input to the game
        response = game.play(update.message.text)
        bot.send_message( chat_id=chat_id, text=response )

    def main(self):
        # main routine for the bot

        token = "mytoken"
        updater = Updater(token)
        dp = updater.dispatcher

        # define the behaviour of the bot
        dp.add_handler(CommandHandler("start", self.start))
        dp.add_handler(MessageHandler(Filters.text, self.respond))

        updater.start_polling()
        updater.idle()

# create the chat bot and run it!
if __name__ == "__main__":

     gamebot = GameBot()
     gamebot.main()
