我试图在主脚本中调用一个模块。我使用require
链接了文件。以下是我的代码的样子:
module Ex36_method
def m_defense
puts "Do you want to play zone or man to man for this possession?"
print "> "
choice = $stdin.gets.chomp
if choice.include? "zone"
zone
elsif choice.include? "man to man"
m_rebound
else
dead("You failed to play defense")
end
end
def zone
puts "The opposition scores a 3!"
end
def m_rebound
puts "The ball rims out and you got a rebound!"
end
end
require_relative 'Ex36_method'
def start
puts "You are in the final minute of game 7 of the NBA finals."
puts "You are down by 3 points."
puts "What do you do: take a 3 pointer that might tie or take a guaranteed 2?"
print "> "
choice = $stdin.gets.chomp
if choice.include? "3 pointer"
puts "You missed! The ball rims out but you got the rebound at 40 seconds."
pass
elsif choice.include? "2 pointer"
puts "You scored! 50 seconds on the clock. Now it's time for defense"
m_rebound
else
dead("Turnover")
end
end
def dead(why)
puts why, "The opposing team scores a 3 and you lose. Better luck next year!"
end
start
当我调用链接模块中的函数时,出现以下错误:
"ex36.rb:16:in `start': undefined local variable or method `m_rebound' for main:Object (NameError)
from ex36.rb:27:in `<main>'"
任何帮助将非常感激。
最佳答案
您已经加载了模块,但是尚未将模块的方法包括到当前作用域中。添加一个include语句:
require_relative 'Ex36_method'
include Ex36_method
def start
