所以我最近一直在学习 ruby，我正在为练习目的编写这段代码，但我似乎无法解决这个问题，任何帮助将不胜感激。
这是我遵循的准则：
clear the screen
greet the player
explain the rules of the game to the player
generate a random number between 0 and x (x being a variable that can be set to any integer)
allow the player n number of guesses (n being a variable)
keep track of the guess history
don't count repeated guesses against the player
congratulate the player when he/she guesses correctly
alert the player when there is only one guess remaining
print the guess history at the end of the game
count number of games won IN A ROW
count number of games won in total
congratulate the play on 3 games won IN A ROW
ask if the player wants to play again
thank the player for playing games if the number of games played is greater than 2
请告诉我这是正在进行的工作，我还没有完成所有指南，但是我的问题是其中的一个特定部分。
这是代码：
guess = Array.new
puts guess.class
def ask()
puts "Please answer in a 'y' or 'n' only!"
puts "Would like to play again?"
end
def guess_check_against()
g = guess.last
unless guess.include?(g) != guess
count+=1
else
puts "sorry you have guessed that number before, Guess Again: "
guess << gets.to_i
count+=1
end
end
puts "what is your name?"
user= gets.chomp
puts "Hello #{user}!!"
max_user_attempts = 4
@attempt_counter = 0
directions = "\nLets play a guessing game! You have
#{max_user_attempts.to_s} guesses before you lose."
print directions
g = guess.last
win = 0
count = 0
play = true
while play == true
puts "Please tell me the max value of the random number: "
max= gets.to_i
num= rand(max)
puts "Ok. The random number is generated between 1 and " + max.to_s + "."
puts "Make your guess: "
guess << gets.to_i
guess_check_against()
@attempt_counter+=1
while guess != num && play != false
if g > num && @attempt_counter < max_user_attempts
print "That's too high. Guess again: "
guess << gets.to_i
guess_check_against()
@attempt_counter+=1
elsif g < num && @attempt_counter < max_user_attempts
print "That's too low. Guess again: "
guess << gets.to_i
guess_check_against()
count+=1
@attempt_counter+=1
else
break
end
end
if @attempts_counter >= max_user_attemtps
puts "Sorry! you lost! Try Again"
break
else @attempts_counter <= max_user_attempts
puts "Correct! You guessed the answer in " + count.to_s + " tries!"
win+=1
end
if win >= 3
puts "Congratulation! you have #{win} number of games in a row"
ask()
answer = gets.chomp!
elsif win < 3
ask()
answer = gets.chomp!
else
break
end
if answer == 'n'
play = false
break
end
if answer == 'y'
play = true
count = 0
end
end
puts "Ok. Goodbye!!"
这是我尝试运行此程序时不断收到的错误：
guessing_game.rb:12:in `guess_check_against': undefined local variable or method `guess' for main:Object (NameError)
from guessing_game.rb:45:in `<main>'
当我尝试使用 irb 运行相同的场景时，它完全可以正常工作。
我无法弄清楚我做错了什么，请帮忙！
