Mind Map Algorithm

Mind Map Algorithm

1. Variables

   • mapLoc
   • PlayerHP

2. Functions

   • A program module that can accept input and return output. Input, if required, is passed to the function using parameters, and output can be returned, if necessary, with return keyword.
     • Set Player Loction
     • Talk to baker
     • Attack Dragon
     • Talk to Dragon

3. Algorithm Techniques

   • Sequence
     • A number of instructions process one after the other
       • START run game FINISH
   • Selection
     • The nest instruction to be executed depends on a condition
       • IF, ELSE, ELSEIF, ENDIF
         • IF chololate milk was selected THEN ADD chocolate milk ELSE ADD milk
   • Iteration
     • WHILE, NOTWHILE
       • While a condition stills exists, the process continues to runs, when the conidtion does not exist, the process stops or changed to another process.
         • Apply in Algorithm Challenge 3
     • REPEAT, UNTIL
       • Apply in Algorithm Challenge 3
       • Repeats process until a certain condition is fullfilled
         • E.g. REPEAT keep walking UNTIL Location found
   • Assignment
     • Assign a value to a variable or memory location
       • DECLARE
         • MapLocation
       • INPUT
         • playerInput
       • OUTPUT
         • Game Message
   • Condition
     • A logical expression that evaluates true or false
       • IF weather is rainy THEN ADD umbrella to bag ELSE leave house
     • Applied in Challenge 2
   • Arithmetic
     • Performs mathematical Calculations
     • +ADD
     • -Subtract
     • Multiplication
     • Divide
     • () parentheses
   • Modularisation
     • Deconstruct a large problem into smaller, more or less indepedent units or modules to allow for the re-use of code and to reduce the complexity of a system, making it easier to find errors.
       • REPEAT, UNTIL
       • WHILE, NOTWHILE

4. Challenges

   • Algorithm Challenge 1
     • Player begins on one of the 4 center squares
       • Selection
         • If mapLoc = 5 OR 6 OR 9 OR 10
       • Assignment
         • mapLoc = ""
     • Set player with 3 health points
       • Assignment
         • playerHP = "3"
   • Algorithm Challenge 2
     • If player talks to baker, he will give the player a loaf of bread
       • Selection
         • If player talks to baker
           • Condition
             • Player must be at bakery location
               • If player is at bakery location
                 • THEN baker given bread
         • Else player does not talk to baker
     • If player eat the loaf of bread, they will gain 5 health points
       • Selection
         • Else player does not to baker
         • If player enter "eat bread"
           • Condition
             • Bread item must be in backpack
               • If bread is not backpack
                 • Player cannot eat the bread
   • Algorithm Challenge 3
     • Player could attack dragon
       • Iteration
         • If dragon was attack 3 times then the game ends
     • Player can talk to dragon
       • If MC answers 3 questions correctly then the game ends
         • Selection
           • If player choose correct answer
             • Game add 1 to score
         • Condition
           • If score = 3
             • Game ends
       • Questions could be riddles
         • Easy
         • Hard
       • True or false Questions
         • Based on the Game
