Need Help with a text based game

Question

I'm trying to make a text based game where you create a character and then battle monsters the problem I'm having is the hit point variable resets to the amount set at the beginning of the game how do I get the variable to change and stay at the new value after taking damage

Answer 1

give this a read, it will fix your problem

Answer 2

you could use hp as a global variable. then it would change outside of the function.

Answer 3

No problem, just arrived. I'll check thru it in a few minutes and get back to ya

Answer 4

does this problem happen alot of mainly area 7? area 7 resets health when it starts

Answer 5

I believe the problem stems from the way you bring in your hp as an argument. inside of your battle function you have an argument of hp, then you battle and the hp changes, but when it is over and you leave the function and start reading the original hp, which has never changed, it results in the same hp from before.

variables inside of functions are specific to that function.

Answer 6

'''
Notice how the following code throws
an error because hp inside the function
doesnt exist. Same principle. The only
reason your not getting the same error
is because instead of the argument a,
you have the argument hp. So when you
call hp inside of your function it,
does exist, and it has the value you
passed it in with, which is your
origional hp's value, but it's not really your hp, it is a new variable that works inside the function that happens to also be called hp
'''

hp=100

def lower(a):
hp=hp-5
print(a)

lower(hp)

Answer 7

thank you so much for all your help I'll post again when I have the issue fixed or if I can't fix it still

Answer 8

well I got it work by getting rid of the battle function. now any of the areas that I want to have a battle have all the code for battling which means my code is very long but it works thank you again for all your help

Answer 9

make sure you declare your variable before your game loop.

health=100
while running:
Your Game Logic

this will have your health go down by 5 and stay there

while running:
health=100
Your Game Logic

This will reset it to 100 everytime

Answer 10

in the beginning of the game the variable is decided like this hp = random.randint(35,50) during a battle if damage is done hp = hp - damage however at the end of the battle function the game resets the hp variable to what ever random number was pick in the beginning so how do I make sure the damage received during the battle stays with the user till the end of the game do I need to make it a counter or do I need to re assign the hp variable at the end of battle

Answer 11

it shouldn't do that unless it is being reassigned. going to need to see code to find the problem

Answer 12

is there a way to upload my code to here I'm writing it on my laptop and have 496 lines of code would like not to have to re write all that

Answer 13

ok email is sent thank you for taking the time to look at this for me

Answer 14

if you go from area 1 to 3 so left when it ask the first time it resets there too I think any time there is a battle it resets

Answer 15

ok so what would you suggest how can I have the ending hp variable in the battle function transfer to the rest of the program? or do I need to think of a new way to do the battle?
