RDShaderSource
==============

**Eredita:** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`

Codice sorgente dello shader (utilizzato da :ref:`RenderingDevice<class_RenderingDevice>`).

.. rst-class:: classref-introduction-group

Descrizione
----------------------

Codice sorgente shader in formato testuale.

Vedi anche :ref:`RDShaderFile<class_RDShaderFile>`. **RDShaderSource** è pensato per essere utilizzato solo con l'API :ref:`RenderingDevice<class_RenderingDevice>`. Non deve essere confuso con la risorsa :ref:`Shader<class_Shader>` di Godot, che è quella che i vari nodi di Godot usano per la programmazione di shader di alto livello.

:ref:`String<class_String>` **get_stage_source**\ (\ stage\: :ref:`ShaderStage<enum_RenderingDevice_ShaderStage>`\ ) |const| :ref:`🔗<class_RDShaderSource_method_get_stage_source>`

Restituisce il codice sorgente per la fase ``stage`` dello shader. Equivale a ottenere uno tra :ref:`source_compute<class_RDShaderSource_property_source_compute>`, :ref:`source_fragment<class_RDShaderSource_property_source_fragment>`, :ref:`source_tesselation_control<class_RDShaderSource_property_source_tesselation_control>`, :ref:`source_tesselation_evaluation<class_RDShaderSource_property_source_tesselation_evaluation>` o :ref:`source_vertex<class_RDShaderSource_property_source_vertex>`.

|void| **set_stage_source**\ (\ stage\: :ref:`ShaderStage<enum_RenderingDevice_ShaderStage>`, source\: :ref:`String<class_String>`\ ) :ref:`🔗<class_RDShaderSource_method_set_stage_source>`

Imposta il codice sorgente per la fase ``stage`` dello shader su ``source``. Equivale a impostare uno tra :ref:`source_compute<class_RDShaderSource_property_source_compute>`, :ref:`source_fragment<class_RDShaderSource_property_source_fragment>`, :ref:`source_tesselation_control<class_RDShaderSource_property_source_tesselation_control>`, :ref:`source_tesselation_evaluation<class_RDShaderSource_property_source_tesselation_evaluation>` o :ref:`source_vertex<class_RDShaderSource_property_source_vertex>`.

\ **Nota:** Se imposti il codice sorgente dello shader di calcolo utilizzando questo metodo direttamente, ricordati di rimuovere l'indicazionespecifica di Godot ``#[compute]``.
