Text-Based Adventure Game

Text-Based Adventure Game

1. Algorithm Constructs

   • Sequence
     • A set of instructions processed one after the other
       • Pick up toothbrush, put toothpaste on brush, ...
   • Assignment
     • The storage of a value in a variable
       • x = 10
       • y = "Hello, World!"
       • n = 2.5
   • Selection & Condition
     • Selection uses a condition to select which line of the program will be executed
       • IF x == 10:
       • ELIF y == "Hello, World!":
       • ELSE:
   • Iteration
     • Used when a piece of code is repeated
       • FOR i IN range(5):
       • WHILE Bool == TRUE:

2. Coding Constructs

   • IF
     • Runs an algorithm when a condition is True
       • IF weather == sunny:
       • IF scorevar == 4:
       • IF Bool == True:
   • ELSE:
     • Runs an algorithm when if or elif statements result as False
       • IF ...: ELSE: print("not met")
   • ELIF
     • Literally short for "else if", allows to check another condition of previous if is not True
       • ELIF y = 10:
       • ELIF "bread" in bag:
   • WHILE
     • Loops through a block of code as long as the condition is True
       • WHILE True:
       • WHILE x > 5:

3. Prescribed Criteria

   • Your story must have at least 10 different variables in total
     • Create a usable variable using Python in the Thonny IDE
       • Thonny is a beginner-based IDE (integrated developer environment) that works on Python. It can be used to create variables
     • Game must have at least 10 different variables
       • userName = input("Insert your name: ")
       • shopChoice = input("What do you buy? ")
     • Variables must be appropriately named and unique
       • Create different variables that don't repeat each other
   • You must have at least two choices for each input (i.e. Yes | No, Left | Right, Buy | Sell
     • Story must have input() keyword, which allows the user to type out answers.
       • INPUT("Type out your answer: \n")
     • Answers must have mutual exclusivity
       • (Yes | No), (Right | Left), (In | Out)
     • Every answer must have an outcome that branches off from the main storyline
       • If the player turns left, they move on to West Forest. If right, then they move to East Forest
   • You must use a WHILE loop
     • Game must have a minimum of 1 WHILE loop
       • WHILE TRUE: (repeated cycle)
     • While loop cycles through the algorithm until a condition is met or an error occurs
       • An algorithm in a WHILE TRUE: statement is broken by the "break" keyword
   • You must use variables that match your storyline
     • Variable names must be appropriate for the storyline
       • In a medieval setting, the variable should be merchantShop instead of spaceShip
     • Variable names must be easy to read and describe their value
       • battleChoice rather than choice_5
     • Variables must be written with correct syntax and data type
       • x = 5 (integer)
       • n = "foo" (string)

4. Self-Determined Criteria

   • Base story on mythical world
     • Mythical characters
       • Elves
       • Dragons
       • Humans
   • Add ASCII Art
     • Visual art created by arranging ASCII characters
       • Dragon image
       • Trophy image
   • Add ANSI colours
     • Sequences that tell a renderer to change colour
       • print("\033[1;32mBold green text\033[0m")

5. Ideas for Story

   • Mythical timeline
     • Base the events, characters, and items on fantasy
       • Elf characters
       • Dragon boss
       • Lightning in a jar
   • Add inventory
     • Create a list that appends items throughout the game
       • bag = []
       • bag.append("something")
   • Base off of chance
     • Random outcomes to random events
       • import random
       • direction = random.choice(["left", "right", "centre"])
