Unity Multiplayer Multijugador Tutorial – Photon 2 (Part 2) (BEGINNER-FRIENDLY – Para Principiantes)
Bienvenido a esta nueva serie de tutoriales sobre la creación de videojuegos multijugador en Unity usando el complemento Photon 2 PUN. Para esta lección, le mostraremos cómo descargar, instalar y configurar el complemento Photon 2 en sus proyectos de Unity. Antes de seguir con cualquiera de las otras lecciones de esta serie de tutoriales, debe completar este video. Proporcionaremos los complementos descargables para todos los demás videos de esta serie, pero estos complementos no incluirán el complemento Photon original. Debe obtenerlo del sitio web oficial de Photon.
Lo primero que deberá hacer en esta lección es crear una cuenta de Photon. Una vez que haya registrado una cuenta, deberá crear un nuevo proyecto de aplicación Photon. Luego deberás completar información sobre tu juego multijugador y luego harás clic en crear. Después de crear una nueva aplicación, deberá copiar el ID de aplicación para más adelante.
De vuelta en Unity, deberá ir a Unity Asset Store y buscar el complemento gratuito PUN 2. Deberá descargar e instalar este complemento en su proyecto. Después de importar este complemento, aparecerá una nueva ventana. Este es el asistente de PUN y debe pegar su AppID de proyecto en esta ventana y luego hará clic en configurar proyecto. Lo siguiente que haremos es establecer nuestra primera conexión con el servidor maestro Photon. Para hacer esto, necesitaremos crear un nuevo script. En este nuevo script, lo único que haremos para este tutorial es inicializar la conexión de red.
