我正在尝试使用 python 制作一个非常简单的游戏。
游戏是蛇梯，玩家从头到尾 (0 - 100)
from random import randint
from time import sleep
board = ["1" ,"2", "3", "4", "5", "6", "7", "8", "9", "10", "11" ,"12", "13", "14", "15",
"16", "17", "18", "19", "20", "21" ,"22", "23", "24", "25", "26", "27", "28", "29",
"30", "31" ,"32", "33", "34", "35", "36", "37", "38", "39", "40", "41" ,"42", "43",
"44", "45", "46", "47", "48", "49", "50", "51" ,"52", "53", "54", "55", "56", "57",
"58", "59", "60", "61" ,"62", "63", "64", "65", "66", "67", "68", "69", "70", "71",
"72", "73", "74", "75", "76", "77", "78", "79", "80", "81" ,"82", "83", "84", "85",
"86", "87", "88", "89", "90", "91" ,"92", "93", "94", "95", "96", "97", "98", "99",
"100"]
def print_board(board):
print (" ".join(board[0:10])) #first row
print (" ".join(board[10:20])) #second row
print (" ".join(board[20:30])) #third row
print (" ".join(board[30:40])) #fourth row
print (" ".join(board[40:50])) #fifth row
print (" ".join(board[50:60])) #six row
print (" ".join(board[60:70])) #seventh row
print (" ".join(board[70:80])) #eight row
print (" ".join(board[80:90])) #ninth row
print (" ".join(board[90:100])) #tenth row
dice = randint(1, 6) #random number 1 - 6
def roll_dice(dice): #function to roll the dice
print ("Rolling the dice...")
sleep(1.5)
print ("..."), dice
return
player_score = 0 #starting point / score
def player(player_score): #for Information
print ("You are now at %d") % player_score
def main(): #game starts
print ("Let's play a game")
while player_score < 100: #This is the problem, the while doesn't recognize player_score
print_board(board)
player_choice = input("put R for Rolling or I for Information: ")
player_choice = player_choice.upper()
if player_choice == "R":
roll_dice(dice)
if dice == 1:
player_score = player_score + 1
print ("Player moves.. ")
player(player_score)
elif dice == 2:
player_score = player_score + 2
print ("Player moves.. ")
player(player_score)
elif dice == 3:
player_score = player_score + 3
print ("Player moves.. ")
player(player_score)
elif dice == 4:
player_score = player_score + 4
print ("Player moves.. ")
player(player_score)
elif dice == 5:
player_score = player_score + 5
print ("Player moves.. ")
player(player_score)
elif dice == 6:
player_score = player_score + 6
print ("Player moves.. ")
player(player_score)
elif player_choice == "I":
player(player_score)
else:
print ("Congratulations, you won the game!")
但问题是，循环甚至没有开始。它说:
"local variable 'player_score' referenced before assignment".
另外:我怎样才能在已经添加了 player_score 的情况下再次继续游戏到 player_choice？
