Workarround pra classe TCPSocket
Este script cria a possibilidade de conexão com a internet via TCPSocket pelo RPGMaker VXAce.
Não devo mais precisar desde script, por tanto não devo mais atualiza-lo, então resolvi postar.
Ela possui dependências não supridas pelo RGSS3, ele inclui a extensão dl, mas não os seus arquivos .rb(com exceção do 'Win32API.rb'), então será necessário repor esses scripts:
Nessa grande código há 10 scripts diferentes, o thread.rb foi criado por Yukihiro Matsumoto (criador do Ruby e é licenciado pela Ruby License (Compatível com GPL))
Os outros não possuem header com os autores, apenas tem algumas RCS IDs com nomes que prefiro não citar aqui, mas de qualquer mode estão sob a Ruby License do mesmo modo.
E por fim, as funções de socket:
Pergunta: Por que não usar Win32API ao invés de dl?o código ficaria 36.5KB mais leve!
Resposta: Prefiro usar dl, Win32API não deve mais ser usada, esta em ativa apenas por compatibilidade, será removida do Ruby em breve.

# ConditionVariable objects augment class Mutex. Using condition variables,

# resource becomes available.

# Example:
#
# require 'thread'
#
# mutex = Mutex.new
# resource = ConditionVariable.new
#
# a = Thread.new {
# mutex.synchronize {
# # Thread 'a' now needs the resource
# resource.wait(mutex)
# # 'a' can now have the resource
# }
# }
#
# b = Thread.new {
# mutex.synchronize {
# # Thread 'b' has finished using the resource
# resource.signal
# }
# }
#

Pergunta: Por que não usar Win32API ao invés de dl?o código ficaria 36.5KB mais leve!
Resposta: Prefiro usar dl, Win32API não deve mais ser usada, esta em ativa apenas por compatibilidade, será removida do Ruby em breve.

Re: Workarround pra classe TCPSocket
Sei que tópico é antigo mais não poderia deixar de agradecer...eu estava desesperado por isso e estava aqui á mais de 1 ano e eu não havia visto....já consegui conectar com os server de NP existentes, o seu em Ruby o em Java o do Master para RMXP e RMVX o script é totalmente funcional, só que peguei ele de outro site e lá vc falou que era nescessário inportar as funcões em .rb e foi o que fiz direcionei para minha lib dl e deu certo.....Obrigado novamente.
