How would I make a text adventure?

Expand Post »

Just wondering how the game would be put together, maybe even a step by step tutorial. I could use this to practice with the commands used without Tkinter or Pygame. This could be a good learning experience.

Re: How would I make a text adventure?

The easiest game would be with a number of rooms. Draw yourself a map of 9 rooms (maybe a 3x3 pattern). Make notes on the map about details of the room, number of doors, contents, pictures, furniture and so on.

Let's say you come into the first room from the south. Now this room has a total of 4 doors, one to the south (S) where you came in, one to the east (E), north (N) and west (W). Ask the player which door he/she wants to enter. Like: "You want to go E, N or W?"

Rooms may have 2, 3 or 4 doors. Now the adventure begins. Some rooms contain a strength potion, or weapon, or some treasure, or cryptic instructions to read, or monsters to fight. When you fight a monster you lose strength. Some monsters are stronger than others. The player starts with a certain amount of strength points and gains more strength by picking up strength potions. Also loses less strength by picking up a better weapons. Each weapon has hit points, the more the better!

Describe the new room as the player enters. Like: "You entered a room that is painted green. There is a picture on the wall of an elderly gentleman. There are 5 gold pieces on the table for you. There are doors to the E and W. Do you want to go E or W?"

The rest is up to your imagination. When the player finds enough treasure (say 50 gold pieces total), he/she will have to get back to the exit alive to win the game. The room descriptions will aid. To make things more difficult, add a basement (stairs/doors to go down or D) or an upstairs (U) floor.

Show the player's present strength, weapon, gold pieces collected, and so on somehere on the screen.

Re: How would I make a text adventure?

I meant, should I def a room class, and make room objects with specific instructions?

Re: How would I make a text adventure?

Could someone please help me by telling me what code structure I should use, and an example? I'm trying, but I have no idea how to make it work. I've tried making a Room class, and making each room a sub-class am I on the right track? I just need pointing in the right direction.

Re: How would I make a text adventure?

It depends what you want to do. If you just want to make a simple fun game, there is no need for class objects. If you want to to do this to learn OOP, then by all means go for it. Your progress will be initially slow, because there is quite a learning curve.

Your approach making a class Room with the basics that all rooms can share, and then a class for each individual room that inherits the class Room makes the most sense. However, a lot of thought has to be put into this approach before any of the fun starts.

Just let us know what you have come up with, and how you would test each class to make sure it does what you want it to do.

Re: How would I make a text adventure?

Text based role playing games (RPG) used to be plentiful in the early days of personal computing. Usually written in Basic, C or Pascal, but I have not seen just a text based RPG in a modern language like Python.

I would most likely define a function for each room and handle all the descriptions, actions, and connections to other rooms from there. Looks like an interesting project and a good way to learn Python skills! Later, as the project grows, you can use classes to group the functions together.

You could start with a 3 by 3 cluster of connected rooms and ask the player to explore all the rooms with the least amount of moves. Hide a few gold pieces and maybe add a secret door or two that can be opend by solving a riddle. As you get the hang of it, you can add weapons, monsters, spells and potions.

There are some GUI based RPGs on the PyGame website, but that gets to be pretty large and complex for beginners.

Re: How would I make a text adventure?

Doing one command at a time, teting each one. Need help, I tried defining gold as a global variable, as it wasn't working when I just created it out of the loop, but the Reading Room won't add 30 gold Where am I going wrong?

global gold

    have no idea how you got there. You look around, and see the front door.
    It is locked and barred, and the bar is nailed down. There is
    no way to open it. There are three other doors in the area. A voice says '50 gold is what you need,
    to escape my grasp, of this take heed!'''
    print

Can you see the problem?

if you want to use gold as global, u might like to put "global gold" inside prompt_rea()

Re: How would I make a text adventure?

You are off to an interesting start! Nice foyer, hehe, almost like mine at home!

Declare the variable gold global in each function that uses this global variable. This would also apply to strength, weapons, or any monster-kill flags. If a monster has been killed in a room you can set the flag so that this monster does not attack again. Of course you could revive the monster and make things much more difficult.

Sorry, I just realized that in your first version you might not go with monsters yet. Just explore, find enough gold, and get out! It will be interesting to read all your room descriptions.
