Après avoir bien galéré pour établir des communications UDP sous Unity, voici les sources (résultats combinées de recherches, bidouilles...) qui fonctionnent. Essayées entre Unity, Blitz3D,VB6, C++. C'est donc du pur générique, standard, de base etc... passe partout
Ca fonctionne aussi entre le mode WebPlayer et le Standalone. Un moyen d'échanger des données entre les différents "builds"
