Enumerations
------------

.. _enum_VisualShaderNodeTexture_Source:

.. rst-class:: classref-enumeration

enum **Source**:

.. _class_VisualShaderNodeTexture_constant_SOURCE_TEXTURE:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_TEXTURE** = ``0``

Use the texture given as an argument for this function.

.. _class_VisualShaderNodeTexture_constant_SOURCE_SCREEN:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_SCREEN** = ``1``

Use the current viewport's texture as the source.

.. _class_VisualShaderNodeTexture_constant_SOURCE_2D_TEXTURE:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_2D_TEXTURE** = ``2``

Use the texture from this shader's texture built-in (e.g. a texture of a :ref:`Sprite<class_Sprite>`).

.. _class_VisualShaderNodeTexture_constant_SOURCE_2D_NORMAL:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_2D_NORMAL** = ``3``

Use the texture from this shader's normal map built-in.

.. _class_VisualShaderNodeTexture_constant_SOURCE_DEPTH:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_DEPTH** = ``4``

Use the depth texture available for this shader.

.. _class_VisualShaderNodeTexture_constant_SOURCE_PORT:

.. rst-class:: classref-enumeration-constant

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **SOURCE_PORT** = ``5``

Use the texture provided in the input port for this function.

.. _enum_VisualShaderNodeTexture_TextureType:

.. rst-class:: classref-enumeration

enum **TextureType**:

.. _class_VisualShaderNodeTexture_constant_TYPE_DATA:

.. rst-class:: classref-enumeration-constant

:ref:`TextureType<enum_VisualShaderNodeTexture_TextureType>` **TYPE_DATA** = ``0``

No hints are added to the uniform declaration.

.. _class_VisualShaderNodeTexture_constant_TYPE_COLOR:

.. rst-class:: classref-enumeration-constant

:ref:`TextureType<enum_VisualShaderNodeTexture_TextureType>` **TYPE_COLOR** = ``1``

Adds ``hint_albedo`` as hint to the uniform declaration for proper sRGB to linear conversion.

.. _class_VisualShaderNodeTexture_constant_TYPE_NORMALMAP:

.. rst-class:: classref-enumeration-constant

:ref:`TextureType<enum_VisualShaderNodeTexture_TextureType>` **TYPE_NORMALMAP** = ``2``

Adds ``hint_normal`` as hint to the uniform declaration, which internally converts the texture for proper usage as normal map.

Property Descriptions
---------------------

.. _class_VisualShaderNodeTexture_property_source:

.. rst-class:: classref-property

:ref:`Source<enum_VisualShaderNodeTexture_Source>` **source** = ``0``

- void **set_source** **(** :ref:`Source<enum_VisualShaderNodeTexture_Source>` value **)**
- :ref:`Source<enum_VisualShaderNodeTexture_Source>` **get_source** **(** **)**

Determines the source for the lookup. See :ref:`Source<enum_VisualShaderNodeTexture_Source>` for options.

.. _class_VisualShaderNodeTexture_property_texture:

.. rst-class:: classref-property

:ref:`Texture<class_Texture>` **texture**

.. rst-class:: classref-property-setget

- void **set_texture** **(** :ref:`Texture<class_Texture>` value **)**
- :ref:`Texture<class_Texture>` **get_texture** **(** **)**

The source texture, if needed for the selected :ref:`source<class_VisualShaderNodeTexture_property_source>`.

.. _class_VisualShaderNodeTexture_property_texture_type:

.. rst-class:: classref-property

:ref:`TextureType<enum_VisualShaderNodeTexture_TextureType>` **texture_type** = ``0``
