Intro to Python II

Up to this point, you've gotten your feet wet by working on a bunch of small Python programs. In this module, we're going to continue to solidify your Python chops by implementing a full-featured project according to a provided specification.

• Solidify the Python basics by implementing a text adventure game
• Get more comfortable writing code that conforms to an (imperfect) specification

The /src directory contains the files adv.py, which is where the main logic for the entire game should live, room.py, which will contain the definition of the Room class, and player.py, which will contain the definition of the Player class.

 <!-- * Hint: the name should be one word for ease in parsing later. -->

In arbitrary order:

• Add scoring

• Subclass items into treasures

• Add a subclass to Item called LightSource.

  • During world creation, add a lamp LightSource to a convenient Room.

  • Override on_drop in LightSource that tells the player "It's not wise to drop your source of light!" if the player drops it. (But still lets them drop it.)

  • Add an attribute to Room called is_light that is True if the Room is naturally illuminated, or False if a LightSource is required to see what is in the room.

  • Modify the main loop to test if there is light in the Room (i.e. if is_light is True or there is a LightSource item in the Room's contents or if there is a LightSource item in the Player's contents).

  • If there is light in the room, display name, description, and contents as normal.

  • If there isn't, print out "It's pitch black!" instead.

  • Hint: isinstance might help you figure out if there's a LightSource among all the nearby Items.

  • Modify the get/take code to print "Good luck finding that in the dark!" if the user tries to pick up an Item in the dark.

• Add methods to notify items when they are picked up or dropped

• Add light and darkness to the game

• Add more items to the game.

• Add a way to win.

• Add more to the parser.

  • Remember the last Item mentioned and substitute that if the user types "it" later, e.g.

    take sword
    drop it
    

  • Add Items with adjectives, like "rusty sword" and "silver sword".

    • Modify the parser to handle commands like "take rusty sword" as well as "take sword".

      • If the user is in a room that contains both the rusty sword and silver sword, and they type "take sword", the parser should say, "I don't know which you mean: rusty sword or silver sword."

• Modify the code that calls on_take to check the return value. If on_take returns False, then don't continue picking up the object. (I.e. prevent the user from picking it up.)

  • This enables you to add logic to on_take to code things like "don't allow the user to pick up the dirt unless they're holding the shovel.

• Add monsters.

• Add the attack verb that allows you to specify a monster to attack.

• Add an on_attack method to the monster class.

• Similar to the on_take return value modification, above, have on_attack prevent the attack from succeeding unless the user possesses a sword item.

• Come up with more stretch goals! The sky's the limit!
