Question

我是Ruby的初学者，我正在做一个非常简单的“游戏”。

我的问题是，我想测试用户是否按1然后滚动一些骰子但我不能使用我的方法。请参阅以下代码了解更多详情：

class Player
#i have some methods but it work
end

class Game
     tot = 0
        def rollDice
            tot = 0
            puts "You roll the dices"
            d1 = rand(1..6)
            puts "Dice 1: #{d1}"
            d2 = rand(1..6)
            puts "Dice 2: #{d2}"
            d3 = rand(1..6)
            puts "Dice #{d3}"
            tot = d1 + d2 + d3
            puts "Your score is  #{tot}"
            return tot
        end 

    #some puts but not important for the coding 

    puts "Press 1 to play or 2 to leave"
    value = gets.chomp
        if value == "1"
            s1 = rollDice
            puts "Why it doesnt work :C #{s1}"

    #[i have a player class but its not important for the moment]
            #player1 = Joueur.new(j1)
            #player2 = Joueur.new(j2)

            #player1.score
            #player2.score
        elsif value== "2"
            exit
        end
end

但我的方法rollDice有未定义的方法错误真谢谢你

您的代码确实有效。但是，你的const qs = require('qs'); const input = { "reply_message": "This is test", "decision[0][label]": "Interested", "decision[0][keyword]": "Interested, call me", "decision[1][label]": "Not Interested", "decision[1][keyword]": "not interested, not", "decision[2][label]": "Call Later", "decision[2][keyword]": "Interested, call me, later" }; const output = qs.parse(qs.stringify(input)); console.log(output); // console: { reply_message: 'This is test', decision: [ { label: 'Interested', keyword: 'Interested, call me' }, { label: 'Not Interested', keyword: 'not interested, not' }, { label: 'Call Later', keyword: 'Interested, call me, later' } ] }定义是缩进的（并且你有第二次rollDice调用），所以我猜你实际上是用其他东西（一个类？）来定义的，这在撰写本文时尚未包含在您发布的代码示例中。

顺便说一句，遵循约定/样式指南我建议您将tot=0重命名为rollDice。

我成功测试的代码就是这个：

roll_dice

示例会话：

def rollDice
    tot = 0
    puts "You roll the dices"
    d1 = rand(1..6)
    puts "Dice 1: #{d1}"
    d2 = rand(1..6)
    puts "Dice 2: #{d2}"
    d3 = rand(1..6)
    puts "Dice #{d3}"
    tot = d1 + d2 + d3
    puts "Your score is  #{tot}"
    return tot
end☠

puts "Press 1 to play or 2 to leave"
value = gets.chomp
if value == "1"
    s1 = rollDice
    puts "Why it doesnt work :C #{s1}"

elsif value== "2"
    exit
end

ruby中未定义的方法
