Hola bienvenidos a este vĆ­deo donde les mostraremos una revisiĆ³n de Ć©ste Ćŗtil asset pagado en la tienda de Unity. Beat Em Up Figth ?āœŠ. El cual nos sirve de gran ayuda a la hora de implementar un juego totalmente funcional y completo del tipo figther para ejecutarlo en un entorno de producciĆ³n. Sin previos conocimientos de programaciĆ³n estĆ” diseƱado tanto para no programadores como para los que si lo son. Espero que lo disfruten y dejen sus comentarios de que tal les parece.
