El Error: NullReferenceException: referencia a objeto no establecida como una instancia de un objeto LevelGeneration.Move () (en activos / scripts / LevelGeneration.cs: 98) LevelGeneration.Update () (en Activos / Scripts / LevelGeneration.cs: 39)
Problema: Estoy creando un programa de generación de actividad dentro de un tutorial e incluso mirado el código fuente. que es idéntica
cada vez que me golpeó la funciono genera unas pocas habitaciones y luego lanza el error enumerado anteriormente. Miré a través de otros pueblos cosas aquí y no es aplicable a mi situación
La línea: if (. RoomDetection.GetComponent () type = 1 && roomDetection.GetComponent () type = 3!.!)
por favor ayuda
