獨立方法本身調用另一種方法

Question

好吧，我認真地吮吸傳遞方法，只要我想從方法返回一些東西。你們能解釋一下我怎麼去傳遞它。 這裏是我的散列

$choosen_gun = {} 
$Weapon = { 
    :Bazoka => ["Bazoka",5], 
    :Machine_gun => ["Machine_gun",1000], 
    :Hand_gun => ["Hand_gun",24,2], 
    :Double_Hand_gun => ["Double_Hand_gun",24,4], 
    :Sniper => ["Sniper",12,1], 
    :Shot_gun => ["Shot_gun",8,2] 
} 

這裏是我的方法支招

def Weapon 
     puts "Now it's time to select your weapon." 
     puts "Please choose a weapon that is good throughout the game." 
     puts "Whenever you are shortage of bullets, please reload it." 
     puts "Please avoid last minute of reloading of weapon." 
     puts "Now choose your weapon based on your own preferences." 
     print "\n" 

     puts "Type 1" 
     puts "Gun Name: Bazoka" 
     puts "Description: A powerful gun that is strong with only 5 bullets." 
     puts "Rating: ★ ★ ★ ★" 
     num = gets.chomp.to_i 

     case num 
      when 1 
      puts "Selection of Bazoka is chosen" 
      puts "Loaded 5 bullets only" 
      $choosen_gun[num] = $Weapon[:Bazoka] 
     end  
    return num 
end 

代碼在調用該方法。用戶會選擇他的武器，並與它的NUM將其添加到$ choosen_gun哈希值，它的回報是NUM什麼類型的用戶

這裏是我的方法的代碼ZombieRoom

def ZombieRoom(w) 
    zombie = { 
     :Construcied => [5], 
     :Invader => [5], 
     :Damned => [5], 
     :Steampunk => [5], 
     :Stoner => [5], 
     :Wasted => [5], 
     :Romero => [5] 
    } 
      puts "Welcome to the worst night mare of Zombie Room" 
      puts "You will be fighting with a random zombie" 


      while true 
      puts ".........." 
      puts "Selecting a random zombie" 
      puts "Selecting your prefered gun...." 
      case w 
        when 1 
        $choosen_gun[1] 
        puts "Your selected gun is #{$choosen_gun[1][0]}" 
        #values = zombie.values 
        #puts values[rand(values.size)] 
        #random_zombie = zombie.keys.sample(1) 
        #puts random_zombie[ 
        random_zombie = zombie.to_a.sample(1).to_h 
        random_zombie.each do |key,value| 
        puts "Your random zombie is #{key}" 
        puts "With a health value of #{value[0]}" 


        puts "Time to take down that zombie now." 
        while true 
        puts "Type Shoot to knock it down or quit." 
        choice = gets.chomp 
        if $choosen_gun[1][1] >= 1 
         health = value[0] -= 1 
         $choosen_gun[1][1] -= 1 
        puts "#{key} health now is #{health}" 
        else 
        puts "Please reload your gun" 
        puts "Reloading......" 
        $choosen_gun[1][1] += 5 
        end 

        if health == 0 
         puts "You have defeated #{key}" 
         puts "Congrats!!!" 
         puts "We are happy for you" 
         puts "Lets begins to collect your prize" 
         CollectPrize() 
        else 
         puts "You did not defeat the #{key} yet" 
        end 

        end 

        end 
     end 
    end 
    end 

這裏是我的代碼方法CollectPrize

def CollectPrize 
     puts "Congratulations on defeating" 
     puts "We would now like to give you some case prizes" 

     print "\n" 

     puts "Please choose only 1 prize for yourself" 
     print "\n" 
     puts "Type 1" 
     puts "$50,000" 
     print "\n" 
     puts "Type 2" 
     puts "$25,000" 
     print "\n" 
     puts "Type 3" 
     puts "$55,000" 
     hoho = gets.chomp.to_f 


     if hoho == 1 
      puts "hehe" 
     end 
end 

這裏，我怎麼叫我的方法

ZombieRoom(Weapon()) 
CollectPrize() 

現在的問題是每當CollectPrize方法被調用時，我輸入我的輸入來收集獎勵示例1，然後打印「$ 50,000」。而不是結束這個問題，它回到了殭屍房間，並繼續在「類型射擊擊倒或退出」循環。有人能告訴我一個正確的方法來解決這個問題，或者還有什麼其他的方式來傳遞一個方法嗎？

Answer 1

您的代碼位於大型while true循環中。由於true始終爲真，所以它永遠不會結束，所以在它調用CollectPrize（）之後，它會返回到while聲明。

你可以通過在CollectPrize()之後插入一條break行來擺脫它，但是還有另一個while true循環。

我想你需要密切關注你想如何退出while循環。

puts "Time to take down that zombie now." 
while true # <---------------- this is ALWAYS going to loop, without end 
    puts "Type Shoot to knock it down or quit." 
    choice = gets.chomp 
    if $choosen_gun[1][1] >= 1 
    health = value[0] -= 1 
    $choosen_gun[1][1] -= 1 
    puts "#{key} health now is #{health}" 
    else 
    puts "Please reload your gun" 
    puts "Reloading......" 
    $choosen_gun[1][1] += 5 
    end 
    if health == 0 
    puts "You have defeated #{key}" 
    puts "Congrats!!!" 
    puts "We are happy for you" 
    puts "Lets begins to collect your prize" 
    CollectPrize() 
    else 
    puts "You did not defeat the #{key} yet" 
    end 
end 

Answer 2

紅寶石常量以大寫字母開頭。方法總是用小寫來定義。

試試這個在IRB

irb(main):001:0> def Weapon 
irb(main):002:1> end 
=> :Weapon 
irb(main):003:0> Weapon 
NameError: uninitialized constant Weapon 

要使用Ruby的命名約定解決您的問題同名的方法：
zombie_room，collect_prize等

那麼這個代碼將工作：
zombie_room(weapon())

你在做什麼並不是真正的通過方法武器來方法殭屍室。 真正發生的是方法武器被執行，然後它返回一個值，並將該值的結果傳遞給方法zombie_room。

我認爲這就是你想要的。

如果您需要傳遞方法，請查閱文檔proc和lambda或僅使用塊。
