----

.. rst-class:: classref-constructor

:ref:`PackedColorArray<class_PackedColorArray>` **PackedColorArray** **(** :ref:`Array<class_Array>` from **)**

Constructs a new **PackedColorArray**. Optionally, you can pass in a generic :ref:`Array<class_Array>` that will be converted.

.. rst-class:: classref-section-separator

----

.. rst-class:: classref-descriptions-group

Method Descriptions

.. _class_PackedColorArray_method_append:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **append** **(** :ref:`Color<class_Color>` value **)**

Appends an element at the end of the array (alias of :ref:`push_back<class_PackedColorArray_method_push_back>`).

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

----

.. _class_PackedColorArray_method_append_array:

.. rst-class:: classref-method

void **append_array** **(** :ref:`PackedColorArray<class_PackedColorArray>` array **)**

Appends a **PackedColorArray** at the end of this array.

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

Finds the index of an existing value (or the insertion index that maintains sorting order, if the value is not yet present in the array) using binary search. Optionally, a ``before`` specifier can be passed. If ``false``, the returned index comes after all existing entries of the value in the array.

\ **Note:** Calling :ref:`bsearch<class_PackedColorArray_method_bsearch>` on an unsorted array results in unexpected behavior.

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

----

.. _class_PackedColorArray_method_clear:

.. rst-class:: classref-method

void **clear** **(** **)**

Clears the array. This is equivalent to using :ref:`resize<class_PackedColorArray_method_resize>` with a size of ``0``.

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

----

----

.. _class_PackedColorArray_method_duplicate:

.. rst-class:: classref-method

:ref:`PackedColorArray<class_PackedColorArray>` **duplicate** **(** **)**

----

.. _class_PackedColorArray_method_fill:

.. rst-class:: classref-method

void **fill** **(** :ref:`Color<class_Color>` value **)**

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

----

.. _class_PackedColorArray_method_has:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **has** **(** :ref:`Color<class_Color>` value **)** |const|

Returns ``true`` if the array contains ``value``.

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

----

.. _class_PackedColorArray_method_insert:

.. rst-class:: classref-method

:ref:`int<class_int>` **insert** **(** :ref:`int<class_int>` at_index, :ref:`Color<class_Color>` value **)**

Inserts a new element at a given position in the array. The position must be valid, or at the end of the array (``idx == size()``).

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

----

.. _class_PackedColorArray_method_is_empty:

.. rst-class:: classref-method

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

Returns ``true`` if the array is empty.

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

----

.. _class_PackedColorArray_method_push_back:

.. rst-class:: classref-method

:ref:`bool<class_bool>` **push_back** **(** :ref:`Color<class_Color>` value **)**

Appends a value to the array.

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

----

.. _class_PackedColorArray_method_remove_at:

.. rst-class:: classref-method

void **remove_at** **(** :ref:`int<class_int>` index **)**

Removes an element from the array by index.

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

----

.. _class_PackedColorArray_method_resize:

.. rst-class:: classref-method

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

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.

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

----

.. _class_PackedColorArray_method_reverse:

.. rst-class:: classref-method

void **reverse** **(** **)**

Reverses the order of the elements in the array.

.. rst-class:: classref-method

:ref:`int<class_int>` **rfind** **(** :ref:`Color<class_Color>` value, :ref:`int<class_int>` from=-1 **)** |const|

Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array.

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

----

.. _class_PackedColorArray_method_set:

.. rst-class:: classref-method

void **set** **(** :ref:`int<class_int>` index, :ref:`Color<class_Color>` value **)**

Changes the :ref:`Color<class_Color>` at the given index.

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

----

.. _class_PackedColorArray_method_size:

.. rst-class:: classref-method

:ref:`int<class_int>` **size** **(** **)** |const|

Returns the number of elements in the array.

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

----

.. _class_PackedColorArray_method_slice:

.. rst-class:: classref-method

:ref:`PackedColorArray<class_PackedColorArray>` **slice** **(** :ref:`int<class_int>` begin, :ref:`int<class_int>` end=2147483647 **)** |const|

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

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)``).

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

----

.. _class_PackedColorArray_method_sort:

.. rst-class:: classref-method

void **sort** **(** **)**

Sorts the elements of the array in ascending order.

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

.. rst-class:: classref-method

:ref:`PackedByteArray<class_PackedByteArray>` **to_byte_array** **(** **)** |const|

Returns a :ref:`PackedByteArray<class_PackedByteArray>` with each color encoded as bytes.

.. rst-class:: classref-section-separator

----

.. rst-class:: classref-descriptions-group

Operator Descriptions
---------------------

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

----

.. _class_PackedColorArray_operator_sum_PackedColorArray:

.. rst-class:: classref-operator

:ref:`PackedColorArray<class_PackedColorArray>` **operator +** **(** :ref:`PackedColorArray<class_PackedColorArray>` right **)**

Returns a new **PackedColorArray** with contents of ``right`` added at the end of this array. For better performance, consider using :ref:`append_array<class_PackedColorArray_method_append_array>` instead.

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

----

.. _class_PackedColorArray_operator_eq_PackedColorArray:

.. rst-class:: classref-operator

:ref:`bool<class_bool>` **operator ==** **(** :ref:`PackedColorArray<class_PackedColorArray>` right **)**

Returns ``true`` if contents of both arrays are the same, i.e. they have all equal :ref:`Color<class_Color>`\ s at the corresponding indices.

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

----

.. _class_PackedColorArray_operator_idx_int:

.. rst-class:: classref-operator

:ref:`Color<class_Color>` **operator []** **(** :ref:`int<class_int>` index **)**

Returns the :ref:`Color<class_Color>` at index ``index``. Negative indices can be used to access the elements starting from the end. Using index out of array's bounds will result in an error.
