Dojo Fighter

By Alex Merced

If you get stuck at anypoint look up the two Wild West Shooter videos in this playlist to give you an idea on how to approach this homework => https://www.youtube.com/playlist?list=PLY6oTPmKnKbZp8Kh6jS5A6j-6H2kGY12e

Objectives

• Practice Creating Classes
• Instantiating Objects
• Having Objects Interact with Each Other

Game Synopsis

You are training at the Local Dojo for a big battle 10 weeks from now (10 turns). Each week you'll make a decision on how to train and after 10 weeks you will have a battle with your opponent.

This Game Takes Input

Remember to get input from the game player use the gets function like below!

# EXAMPLE: copy and paste this and try it out in your own terminal

puts "Do you want to |fight| or |run|?"

input = gets.chomp #chomp trims whitespace

if input == "fight"
    puts "you are fighting"
elsif input == "run"
    puts "you are running"
end

Step 1 - Create Our Set Pieces

When creating any application we should first define our classes that we will be using. Create two classes that match the following psuedo code.

Fighter Class 🤼

🍬 Instance properties

# name
# => string : has getter no setter

# defense
# => number: has getter and setter

# strength
# => number : has getter and setter

# luck
# => number : has getter and setter

# life
# => number : has getter and setter

❗ *getters* are methods to get a value

❗ *setters* are methods to alter a value

HINT: To make it easier to create your getter and setters google: attr_accessor, attr_reader and attr_writer

🍬 Fighter Methods

# attack(opponent)
# => function that takes `opponent` object as argument and does damage equal to strength

HINT

    def attack(opp)
        damage = @strength - opp.defense
        if damage <= 0
            puts "#{name} could not do damage to #{opp.name}"
        else
            opp.life = opp.life - damage
            puts "#{opp.name} took #{damage} now has #{opp.life} life left"
        end
    end

❗ STOP Before you go further test your fighter class, create a new fighter or two and test the functions and properties.

ken = Fighter.new("Ken", 5,5,5,5)
ryu = Fighter.new("Ryu", 7,7,7,7)

puts ken.life
ryu.attack(ken)
puts ken.life

Step 2 - Dojo Class 🏟️

This class represents how the fighter trains each week, so the methods represent activities at the dojo. There is only one dojo so all the methods should be class methods no instance methods.

methods to create:

# lift_weights(fighter)
# => takes in fighter and adds 1 to strength

# endurance_training(fighter)
# => takes in fighter and adds 1 to defense

# coin_in_fountain(fighter)
# => takes in fighter and adds 1 to strength

HINT

class Dojo
    def self.lift_weights(fighter)
        fighter.strength += 1
        puts "You are feeling your strength surge"
    end
end

ken = Fighter.new("Ken", 5,5,5,5)
ryu = Fighter.new("Ryu", 7,7,7,7)

puts ryu.strength
Dojo.lift_weights(ryu)
puts ryu.strength

Step 3 - Creating the Game

👉 Follow the psuedocode for the game below

Step 1 - create character

# welcome player to game and ask for their name
# =>  use `gets` to get players name in variable

# create new fighter ```player = Fighter.new(name, 0,0,0, 10)```
# =>  all their stats start at 0 except life which is 10 *

# create their opponent ```Akuma = Fighter.new("Akuma", 4,4,4,10)```

Step 2 - Training Loop

you can get creative here, you can add to the fighter's strength, health or endurance

# put a prompt telling the story and explaining the game
# create a while look that will loop `10` times
# => prompts will pause the loop and wait for the user to input a choice
    # in the while loop ask the player how they'd like to train that week
    # based on their choice invoke the right dojo function to train the player

Step 3 - The Battle

# after the previous while loop create prompt explaining the big battle has arrived
# create an infinite loop
# have the player and their opponent take turns attacking each other
# at the end of each loop check the life of both fighters
# if one is at 0 or below, break the loop and declare the survivor the winner

HINT

while true
    player.attack(akuma)
    akuma.attack(player)

    if player.life <= 0
        puts "Akuma has won the battle!"
        break
    end

    if akuma.life <= 0
        puts "#{player.name} has won the battle!"
        break
    end
end

👉 Things to Consider

• Make sure you tested the fighters thoroughly so you don't end up with an infinite loop cause they can't do damage to each other
• They accidentally increase each others life
• (you may want to add a test in attach in case they end up doing negative damage)

Hungry For More

Want to make your game more fun!

• Make the opponent have random stats
• Use the Luck stat to test whether an attack may miss
• add other activities at the dojo
• be creative
