NavigationPolygon
=================
**Sperimentale:** This class may be changed or removed in future versions.
**Eredita:** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
Una mesh di navigazione 2D che descrive una superficie attraversabile per la ricerca del percorso.
.. rst-class:: classref-introduction-group
Descrizione
----------------------
Una mesh di navigazione può essere creata sia preparandola con l'aiuto di :ref:`NavigationServer2D<class_NavigationServer2D>`, sia aggiungendo manualmente i vertici e gli array di indici dei poligoni convessi
Per preparare una mesh di navigazione è necessario aggiungere almeno un contorno che definisce i limiti esterni dell'area preparata.

\ **Nota:** Il raggio deve essere uguale o superiore a ``0.0``. Se il raggio è ``0.0``, non sarà possibile correggere sovrapposizioni non valide tra contorni e altri errori di precisione durante il processo di preparazione.
