[textRPG]How to keep random creating of class and class atrributes every time i run a program[Python-CodePudding

I am trying some text based rpg game as a beginner in python. But i am struggling to get done one thing.

If i use while loop to run program 5 times. So i want repeat killing monster but without saving his attributes. If you run this code, character kills a monster in couple of moves and appends his experience to himself and monster hp decreases to <= 0 and dies.

Looping whole program does not work, randomly created monster is still the same, i just want to create new monster with new random attributes every time i loop program. It is possible? I am new to this and can't figure it out at this moment. Some tips ?

Here is some code but without while loop: final output is to loop this menu and fight simulator to gain exp and items from random monsters.

import random
import time

# List of items to drop
normal_items = ['Copper ore', 'Apple', 'Animal skin', 'Stone', 'Feather', 'Rotten egg', 'Bag of sand', "Simple dagger", "Blue flower"]
rare_items = ['Energized wand', 'Staff of purity', 'Enhanced gloves', 'Adamant chest plate']
legendary_items = ['Crown of Immortality', 'Robe of fire-dragon']

drop_chance_dice = random.randint(1, 100)

# Simple drop chance function


def dice():

    if drop_chance_dice <= 70:
        random_choice = (random.choice(normal_items))
        print(f"You got: {random_choice} ")
    if 70 <= drop_chance_dice <= 98:
        random_choice = (random.choice(rare_items))
        print(f"You got: {random_choice} ")
    if 99 <= drop_chance_dice <= 100:
        random_choice = (random.choice(legendary_items))
        print(f"Congratulations! You got an legendary item: {random_choice}")

I tried: to create new unique monster with new randomly created attributes every time i run program. I used while loop but monster is not "respawning"

I expect: Some sort of simulator, after i kill monster, program creates new one and my character gains experience and items every fight.

I wonder: If there is some method to makes this class unique every loop.

CodePudding user response：

Here is HOW-TO to achieve all goals in your question:

each time generate monsters with different parameters
respawn monsters

First you create 3 sepreate functions that would return a new monster - the class of returned value is always the same (Monster) but they return new instances on each call:

def get_rat():
    return Monster("You fight vs: \n", "Rat", ...)

def get_giant_rat():
    return Monster(...)

def get_rat_boss():
    reutrn Monster(...)

You will also need to modify how you select monsters. I would suggest to create list of functions - so instead of selecting a monster you select a function, that generates monster:

# This should replace the list_of_mob
list_of_mob_generators = [get_rat, get_giant_rat, get_rat_boss]

And the last - you should select monster on each loop interation in main menu (so the monster could respawn). The shortest way is to change your global variable:

event_mob = None  # we change event_mob initially to None - we will select in later

def menu_dungs():
    global event_mob  # this is new
    asking = input("Where do you want to go?: 1.Rat Nest or 2.Northern Forest :")
    if asking == "1":
        event_mob_generator = random.choice(list_of_mob_generators)  # get one of the functions
        event_mob = event_mob_generator()  # call the function to get monster

        print("You entering rat nest.. good luck!\n")
        time.sleep(1)
        print("Some ugly creature stays on your way!")
        print(f"{event_mob.name} is looking at you!")
        # and this condition has changed, since we do not have one instance of each monster anymore
        if event_mob.name == 'Rat':
            introduction_of_monster_ratnest(event_mob)
            escape_or_fight()
        elif event_mob.name == 'Giant Rat':
            introduction_of_monster_ratnest(event_mob)
            escape_or_fight()
        elif event_mob.name == 'Rat Boss':
            introduction_of_monster_ratnest(event_mob)
            escape_or_fight()
        else:
            print("Something went horribly wrong.. Don't even ask..")
    ... # and so on

and of course do not forget a while loop for main menu =)

Thanks for help, program works as i wanted but still shows me 8 yellow errors in attack() function. Cannot find reference 'hp' in 'None' etc. maybe because this event_mob = None ? Could you run this code and see what is going on ? very likely i did put something in wrong place..
