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:

#  resource = ConditionVariable.new
# 
#  a = Thread.new {
#    mutex.synchronize {
#      # Thread 'a' now needs the resource
#      resource.wait(mutex)

#  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.

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.
