can you show your current code

@wintry garnet hi

[wintry garnet]

it's not finished ok?

[fervent ledge]

it's fine

[wintry garnet]

k

[fervent ledge]

i really just need to know how you are storing the game state

[desert dune]

Its possible

[tawny perch]

yes, but it depends on where your files are, but yes if you import them

# Minecraft Terminal version

player_infos = {
    "name": "",
    "gender": "",
    "age": 0,
}

stats = {

            print("")
            print(f"You leveled up! Current level: {stats['level']}")
        
        if stats["level"] == 100:
            stats["XP"] = 0

oh my bad

[fervent ledge]

so you have

player_infos = {
    "name": "",
    "gender": "",
    "age": 0,
}

stats = {
    "lives": 3,
    "hp": 100,
    "shield": 0,
    "level": 0,
    "XP": 0
}

storing the game state right

[wintry garnet]

I know BUT, if the user exit the game, all the stats will be gone

[fervent ledge]

i know

[wintry garnet]

oh

[fervent ledge]

this can be reasonably serialized into a json string

{"name": "", "gender": "", "age": 0} is our json string

[wintry garnet]

can it be reused?

[fervent ledge]

json.loads will deserialize our string back into an object

so far so good?

json is a built-in python module

it has the functions dumps that serializes an object into a json string and loads that deserializes it back into a python object, which in this case is a dict

@wintry garnet you there?

[wintry garnet]

yes

[fervent ledge]

so we have a string that will we can store right?

we store this string in a file

and we can recover the game state later on

right?

you following so far?

[wintry garnet]

uhm

yes

[fervent ledge]

what's your question

you can just ask

[wintry garnet]

no I was just reading

so I typed uhm because I didn't know what to type

my bad

[fervent ledge]

do you know how to write a file yet?

[wintry garnet]

what do you mean by write a file?

[fervent ledge]

there's a comprehensive documentation at https://docs.python.org/3/tutorial/inputoutput.html#reading-and-writing-files if you want to refer to it

[wintry garnet]

ok thank you!

I gotta go now

cya

[fervent ledge]

for when you get back:

from pathlib import Path

with Path("test.json").open("w") as f:
    f.write("test")

will create a file called test.json

[wintry garnet]

oh

[fervent ledge]

containing the string "test"

though in this case what we want to store is not test

but rather the json string from earlier

[fervent ledge]

which is this

obviously im not giving you the full answer key, but i think you should be able to synthesize these information that i have given you to write a function that writes your game state into a file

and to write a function that reads the file

and recover the game state from the string that we wrote

if you have any questions you can ask them
