Shop() run down

 This class is responsible for running the shop and creating the Item() objects.

Constructor:

def __init__(self):
    self.items = []
    f = open("items.csv")
    fReader = csv.reader(f)
    for line in fReader:
        if line == []:
            continue
        self.items.append(Item(line[2], line[0], int(line[1]), int(line[3])))
    f.close()

When the class is called the class list items are filled with Item() objects created by opening items.csv and taking the data in there to instantiate the items. Then we close the file.

WhoIsShopping():

def whoIsShopping(self, squad :list):
    counter = 0
    choices = []
    print("Who is shopping?")
    for member in squad:
        if member.level > 0:
            print(str(counter) + ": " + member.displayName)
            choices.append(counter)
            counter += 1
    selection = inputAndCheck("Selection: ", choices)
    return squad[selection]

This function does what it says, it prompts for and receives the selection of a playableCharacter() for shopping. It returns the specified playableCharacter().

ShopDisplay():

def shopDisplay(self, member :PlayableCharacter):
    print("Stingy Man: welcome traveler, as long as you have gold your welcome! What are you looking for today?")
    counter = 0
    choices = []
    for item in self.items:
        print(str(counter) + ": " + item.name + "(" + str(item.cost) + " gold)")
        choices.append(counter)
        counter += 1
    choices.append(counter)
    print(str(counter) + ": Leave")
    return inputAndCheck(member.displayName + "'s action: ", choices)

This function displays all the items available in the store, by iterating over items.

 

Buy():

def buy(self, item :Item, gold, user :PlayableCharacter):
    if item.cost <= gold:
        if item.effect == "AtkPhy":
            if user.energyName != "Mana":
                return item
            else:
                return user.displayName + " can't use that(press enter to continue)"
        elif item.effect == "AtkMag":
            if user.energyName == "Mana":
                return item
            else:
                return user.displayName + " can't use that(press enter to continue)"
        else:
            return item
    else:
        return "insufficient gold"

This function simply checks if the player has sufficient gold, and ensures that a physical attack item isn’t bought for a magical character, and a magical attack item isn’t bought by a  physical attack character. (magical characters have “mana” as there stamina)

 

StoreRun():

def storeRun(self, squad :list, gold :int):
    done = False
    while not done:
        shopper = self.whoIsShopping(squad)
        os.system("cls")
        print("gold: " + str(gold))
        action = self.shopDisplay(shopper)
        if action >= len(self.items):
            pass
        else:
            result = self.buy(self.items[action], gold, shopper)
            if isinstance(result, Item):
                input("Stingy man: here you go! thankyou for your business!(press enter to continue)")
                shopper.inventory.append(result)
                if result.usage != "hp":
                    shopper = result.effectHandler(shopper)
                gold = gold - result.cost
            else:
                input(result)
        result = inputAndCheck("are you done shopping?(0: no, 1: yes)", [0, 1])
        counter = 0
        for ally in squad:
           if ally.displayName == shopper.displayName:
               squad[counter] = shopper
           counter += 1

        if result == 1:
            done = True
    return [squad, gold]

This is the function that implements all of the previously mentioned functions. I loops through all the function calls so that the player can shop as many times as they want, until they decide to leave. At the end of each purchase, the player is asked if they want to leave and if they respond yes (1) then done is set to true, thus ending the loop.
