TextureArray
============

**Inherits:** :ref:`TextureLayered<class_TextureLayered>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`

Array of textures stored in a single primitive.

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

Description
-----------

**TextureArray**\ s store an array of :ref:`Image<class_Image>`\ s in a single :ref:`Texture<class_Texture>` primitive. Each layer of the texture array has its own mipmap chain. This makes it is a good alternative to texture atlases. See also :ref:`Texture3D<class_Texture3D>`.

\ **TextureArray**\ s must be displayed using shaders. After importing your file as a **TextureArray** and setting the appropriate Horizontal and Vertical Slices, display it by setting it as a uniform to a shader, for example (2D):

::

    shader_type canvas_item;
    
    uniform sampler2DArray tex;
    uniform int index;
    
    void fragment() {
        COLOR = texture(tex, vec3(UV.x, UV.y, float(index)));
    }

Set the integer uniform "index" to show a particular part of the texture as defined by the Horizontal and Vertical Slices in the importer.

\ **Note:** When sampling an albedo texture from a texture array in 3D, the sRGB -> linear conversion hint (``hint_albedo``) should be used to prevent colors from looking washed out:

::

    shader_type spatial;
    
    uniform sampler2DArray tex : hint_albedo;
    uniform int index;
    
    void fragment() {
        ALBEDO = texture(tex, vec3(UV.x, UV.y, float(index)));
    }

\ **Note:** **TextureArray**\ s can only be sampled in shaders in the GLES3 backend. In GLES2, their data can be accessed via scripting, but there is no way to render them in a hardware-accelerated manner.

void **create** **(** :ref:`int<class_int>` width, :ref:`int<class_int>` height, :ref:`int<class_int>` depth, :ref:`Format<enum_Image_Format>` format, :ref:`int<class_int>` flags=7 **)**

Creates the TextureArray with specified ``width``, ``height``, and ``depth``. See :ref:`Format<enum_Image_Format>` for ``format`` options. See :ref:`Flags<enum_TextureLayered_Flags>` enumerator for ``flags`` options.
