PackedByteArray
===============

A packed array of bytes.

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

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

An array specifically designed to hold bytes. Packs data tightly, so it saves memory for large array sizes.

\ **PackedByteArray** also provides methods to encode/decode various types to/from bytes. The way values are encoded is an implementation detail and shouldn't be relied upon when interacting with external apps.

\ **Note:** Packed arrays are always passed by reference. To get a copy of an array that can be modified independently of the original array, use :ref:`duplicate<class_PackedByteArray_method_duplicate>`. This is *not* the case for built-in properties and methods. The returned packed array of these are a copies, and changing it will *not* affect the original value. To update a built-in property you need to modify the returned array, and then assign it to the property again.

.. note::

	There are notable differences when using this API with C#. See :ref:`doc_c_sharp_differences` for more information.

Returns a new **PackedByteArray** with the data decompressed. Set ``buffer_size`` to the size of the uncompressed data. Set the compression mode using one of :ref:`CompressionMode<enum_FileAccess_CompressionMode>`'s constants.

\ **Note:** Decompression is not guaranteed to work with data not compressed by Godot, for example if data compressed with the deflate compression mode lacks a checksum or header.

.. _class_PackedByteArray_method_decompress_dynamic:

.. rst-class:: classref-method

:ref:`PackedByteArray<class_PackedByteArray>` **decompress_dynamic**\ (\ max_output_size\: :ref:`int<class_int>`, compression_mode\: :ref:`int<class_int>` = 0\ ) |const| :ref:`🔗<class_PackedByteArray_method_decompress_dynamic>`

Returns a new **PackedByteArray** with the data decompressed. Set the compression mode using one of :ref:`CompressionMode<enum_FileAccess_CompressionMode>`'s constants. **This method only accepts brotli, gzip, and deflate compression modes.**\ 

This method is potentially slower than :ref:`decompress<class_PackedByteArray_method_decompress>`, as it may have to re-allocate its output buffer multiple times while decompressing, whereas :ref:`decompress<class_PackedByteArray_method_decompress>` knows it's output buffer size from the beginning.

GZIP has a maximal compression ratio of 1032:1, meaning it's very possible for a small compressed payload to decompress to a potentially very large output. To guard against this, you may provide a maximum size this function is allowed to allocate in bytes via ``max_output_size``. Passing -1 will allow for unbounded output. If any positive value is passed, and the decompression exceeds that amount in bytes, then an error will be returned.

\ **Note:** Decompression is not guaranteed to work with data not compressed by Godot, for example if data compressed with the deflate compression mode lacks a checksum or header.

.. rst-class:: classref-method

|void| **fill**\ (\ value\: :ref:`int<class_int>`\ ) :ref:`🔗<class_PackedByteArray_method_fill>`

.. _class_PackedByteArray_method_get_string_from_ascii:

.. rst-class:: classref-method

:ref:`String<class_String>` **get_string_from_ascii**\ (\ ) |const| :ref:`🔗<class_PackedByteArray_method_get_string_from_ascii>`

Converts ASCII/Latin-1 encoded array to :ref:`String<class_String>`. Fast alternative to :ref:`get_string_from_utf8<class_PackedByteArray_method_get_string_from_utf8>` if the content is ASCII/Latin-1 only. Unlike the UTF-8 function this function maps every byte to a character in the array. Multibyte sequences will not be interpreted correctly. For parsing user input always use :ref:`get_string_from_utf8<class_PackedByteArray_method_get_string_from_utf8>`. This is the inverse of :ref:`String.to_ascii_buffer<class_String_method_to_ascii_buffer>`.

Converts UTF-8 encoded array to :ref:`String<class_String>`. Slower than :ref:`get_string_from_ascii<class_PackedByteArray_method_get_string_from_ascii>` but supports UTF-8 encoded data. Use this function if you are unsure about the source of the data. For user input this function should always be preferred. Returns empty string if source array is not valid UTF-8 string.

.. rst-class:: classref-method

:ref:`bool<class_bool>` **is_empty**\ (\ ) |const| :ref:`🔗<class_PackedByteArray_method_is_empty>`

:ref:`int<class_int>` **resize**\ (\ new_size\: :ref:`int<class_int>`\ ) :ref:`🔗<class_PackedByteArray_method_resize>`

Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size. Calling :ref:`resize<class_PackedByteArray_method_resize>` once and assigning the new values is faster than adding new elements one by one.

.. rst-class:: classref-item-separator

----

.. _class_PackedByteArray_method_reverse:

.. rst-class:: classref-method

|void| **reverse**\ (\ ) :ref:`🔗<class_PackedByteArray_method_reverse>`

Returns the slice of the **PackedByteArray**, from ``begin`` (inclusive) to ``end`` (exclusive), as a new **PackedByteArray**.

The absolute value of ``begin`` and ``end`` will be clamped to the array size, so the default value for ``end`` makes it slice to the size of the array by default (i.e. ``arr.slice(1)`` is a shorthand for ``arr.slice(1, arr.size())``).

If either ``begin`` or ``end`` are negative, they will be relative to the end of the array (i.e. ``arr.slice(0, -2)`` is a shorthand for ``arr.slice(0, arr.size() - 2)``).

Returns a copy of the data converted to a :ref:`PackedFloat32Array<class_PackedFloat32Array>`, where each block of 4 bytes has been converted to a 32-bit float (C++ ``float``).

The size of the input array must be a multiple of 4 (size of 32-bit float). The size of the new array will be ``byte_array.size() / 4``.

If the original data can't be converted to 32-bit floats, the resulting data is undefined.

Returns a copy of the data converted to a :ref:`PackedFloat64Array<class_PackedFloat64Array>`, where each block of 8 bytes has been converted to a 64-bit float (C++ ``double``, Godot :ref:`float<class_float>`).

The size of the input array must be a multiple of 8 (size of 64-bit double). The size of the new array will be ``byte_array.size() / 8``.

The size of the input array must be a multiple of 4 (size of 32-bit integer). The size of the new array will be ``byte_array.size() / 4``.

If the original data can't be converted to signed 32-bit integers, the resulting data is undefined.
