Hi everybody,

My application isn't working well. Let me try to explain what's wrong.
When I run my program appears something like:

ruby pedrapapeltesoura.rb
Digite pedra, papel ou tesoura: pedra
1
tesoura
pedra
alguem ganhou

This 1 that appears above is the value of resultSorteio variable, the
content of this variable come from a method which random a number
between 1 to 3. tesoura is the value of the variable maquina, however if
the variable resultSorteio is 1 the variable maquina should be pedra and
not be tesoura, and sometimes the variable is empty...if you try to play
many times you can see where is the word tesoura above will appears
nothing. Does somebody help me please. Here is my code:

class Jogo

def sorteia
opcoes = ['pedra','papel','tesoura']
numero = 1 + rand(3)
return numero
end

def joga(usuario)

result = sorteia()
resultSorteio = result.to_i

puts(resultSorteio)
puts (('11' * 2).to_i/2)
if resultSorteio == 1 then
maquina = "pedra"
if resultSorteio == 2 then
maquina = "papel"
else
maquina = "tesoura"
end

end

puts(maquina)
puts(usuario)
usuario.chop
if usuario == maquina then
puts("empatou")
else
puts("alguem ganhou")
end

end
end

j = Jogo.new()

print "Digite pedra, papel ou tesoura: "
opcaoUsuario = gets()

j.joga(opcaoUsuario)

Your if was nested funny, this should do what you want, I think:

class Jogo

def sorteia
opcoes = ['pedra','papel','tesoura']
numero = 1 + rand(3)
return numero
end

def joga(usuario)

result = sorteia()
resultSorteio = result.to_i

puts(resultSorteio)
puts (('11' * 2).to_i/2)
if resultSorteio == 1 then
maquina = "pedra"
elsif resultSorteio == 2 then
maquina = "papel"
else
maquina = "tesoura"
end

puts(maquina)
puts(usuario)
usuario.chop
if usuario == maquina then
puts("empatou")
else
puts("alguem ganhou")
end

end
end

j = Jogo.new()

print "Digite pedra, papel ou tesoura: "
opcaoUsuario = gets()

j.joga(opcaoUsuario)

Try this:

def sorteia
return ['pedra','papel','tesoura'][rand(3)]
end

def joga(usario)
macina = sorteia

puts usario.chop == macina ? empatou" : "alguem ganhou"
end

I'm don't read enough Portugese (?) to fully understand the intent of your code, but the above should do pretty much the same as what you've shown below, but should never give you randomly blank results.

Hope this helps

I'm not so good in English but I understood that I shoud show you my
whole code. I put a different if like what the guy above suggested and I
worked. Thanks:

class Jogo

def sorteia
opcoes = ['pedra','papel','tesoura']
numero = 1 + rand(3)
return numero
end

def joga(usuario)

result = sorteia()
resultSorteio = result.to_i

puts(resultSorteio)
if resultSorteio == 1 then
maquina = "pedra"
elsif resultSorteio == 2 then
maquina = "papel"
else
maquina = "tesoura"
end


puts(maquina)
puts(usuario)
usuario.chop
if usuario == maquina then
puts("empatou")
else
puts("alguem ganhou")
end

end
end

j = Jogo.new()

print "Digite pedra, papel ou tesoura: "
opcaoUsuario = gets()

j.joga(opcaoUsuario)
