Python Dice Functions

PYTHON DICE FUNCTIONS

Dice games like D&D and Fighting Fantasy were very popular when I was growing up, so I thought I'd try to make a text adventure in Python based on The Warlock of Firetop Mountain. Most of the game is based around dice rolls so it is pretty easy to replicate.

The interesting part is how to store and use the data effectively, and this ended up as a really useful exercise in lists, dictionaries, classes with Python. I have set up a project on Bitbucket with specific scripts for the game and the repo can be accessed here.

ROLLING DICE

The function rollDice will print two numbers between 1 annd 6.

import random
def rollDice():
    print random.randint(1, 6)
    print random.randint(1, 6)

This became n number of dice, all D6. It uses diceInput as a range and rolls a D6 for every number in that range.

import random
def chooseDice():
    diceInput = input('How many dice? 1-n: ')
    for i in range(diceInput):
        print random.randint(1,6)
    raw_input('press ENTER')

And that became an input for n dice with n sides.

import random
def nDiceSides():
    diceInput = input('How many dice? ')
    sideInput = input('How many sides for each dice? ')
    for i in range(diceInput):
        print random.randint(1,sideInput)
    raw_input('press ENTER')

I wouldn't include import random with every function. It's only bc I tested these as individual scripts.

The two D6 roll can be modified to give min/max settings for the number of sides, and to sit inside a while loop so it keeps prompting after every roll.

def rollDiceLoop():
    min = 1
    max = 6
    rollEm = raw_input("Roll two D6? Y/N: ")
    while rollEm == "y" or rollEm == "Y":
        print random.randint(min, max)
        print random.randint(min, max)
        rollEm = raw_input("Roll two D6? Y/N: ")
    else:
        print ('Nothing rolled.')
    raw_input('press ENTER')

One and two D6 will be fine for a text game, but to turn them into something useful they need to be modified slightly. Print is OK to see the result, but the function should return the value of the roll. With two D6, the total of the two rolls should be returned.

def rollDie():
    roll = random.randint(1, 6)
    return roll

def rollDice():
    rollOne = random.randint(1, 6)
    rollTwo = random.randint(1, 6)
    return rollOne + rollTwo

Fighting Fantasy uses attributes of SKILL, STAMINA and LUCK in a dice-based combat system. This can be setup in a simple simple script with two entities, the player and the enemy. Both have SKILL and STAMINA attributes determined with D6 rolls. In combat, the player rolls a D6 and adds it to their skill. This is their attack strength. Then player then does the same for the enemy. The greater attack strength wins, and 1 point is subtracted from the loser's STAMINA until it reaches 0 and someone is dead.

import random

def rollDie():
    roll = random.randint(1,6)
    return roll

raw_input('Press ENTER to determine levels... ')

pSkill = rollDie()
eSkill = rollDie()
pStamina = rollDie()
eStamina = rollDie()

print
print 'Player skill = ', pSkill
print 'Player stamina = ', pStamina
print 'Enemy skill = ', eSkill
print 'Enemy stamina = ', eStamina
print
print 'FIGHT!'

combat = 1
while combat == 1:
    print
    raw_input('Press ENTER to attack... ')
    print

    pAttack = pSkill + rollDie()
    eAttack = eSkill + rollDie()

    print 'player attack = ', pSkill, '+', pAttack-pSkill, '=', pAttack
    print 'enemy attack = ', eSkill, '+', eAttack-eSkill, '=', eAttack

    if pAttack > eAttack:
        eStamina -= 1
        print 'YOU WOUNDED IT'  
    else:
        pStamina -=1
        print 'YOU GOT HIT'

    print 'Player stamina = ', pStamina
    print 'Enemy stamina = ', eStamina
    
    if eStamina == 0:
        print
        print 'VICTORY!'
        exit()
    elif pStamina == 0:
        print
        print 'YOU ARE DEAD'
        exit()

The initial values are set up before the combat, and then it's a simple while loop to simulte the rolling of dice for each round of combat. The loop continues until the stamina of either player or enemy reaches 0.
