Vector2i
========
A 2D vector using integer coordinates.
.. rst-class:: classref-introduction-group
Description
-----------
A 2-element structure that can be used to represent 2D grid coordinates or any other pair of integers.
It uses integer coordinates and is therefore preferable to :ref:`Vector2<class_Vector2>` when exact precision is required. Note that the values are limited to 32 bits, and unlike :ref:`Vector2<class_Vector2>` this cannot be configured with an engine build option. Use :ref:`int<class_int>` or :ref:`PackedInt64Array<class_PackedInt64Array>` if 64-bit values are needed.
\ **Note:** In a boolean context, a Vector2i will evaluate to ``false`` if it's equal to ``Vector2i(0, 0)``. Otherwise, a Vector2i will always evaluate to ``true``.
