BitmapFont
==========
**Inherits:** :ref:`Font<class_Font>` **<** :ref:`Resource<class_Resource>` **<** :ref:`Reference<class_Reference>` **<** :ref:`Object<class_Object>`
Renders text using fonts under the `BMFont <https://www.angelcode.com/products/bmfont/>`__ format.
Handles files with the ``.fnt`` extension.
.. rst-class:: classref-introduction-group
Description
-----------
Renders text using ``*.fnt`` fonts containing texture atlases. Supports distance fields. For using vector font files like TTF directly, see :ref:`DynamicFont<class_DynamicFont>`.

----
.. _class_BitmapFont_property_distance_field:
.. rst-class:: classref-property
:ref:`bool<class_bool>` **distance_field** = ``false``
.. rst-class:: classref-property-setget
- void **set_distance_field_hint** **(** :ref:`bool<class_bool>` value **)**
- :ref:`bool<class_bool>` **is_distance_field_hint** **(** **)**
If ``true``, distance field hint is enabled.

- void **set_fallback** **(** :ref:`BitmapFont<class_BitmapFont>` value **)**
- :ref:`BitmapFont<class_BitmapFont>` **get_fallback** **(** **)**
The fallback font.
.. rst-class:: classref-item-separator

.. rst-class:: classref-property
:ref:`float<class_float>` **height** = ``1.0``
.. rst-class:: classref-property-setget

Method Descriptions
-------------------
.. _class_BitmapFont_method_add_char:
.. rst-class:: classref-method
void **add_char** **(** :ref:`int<class_int>` character, :ref:`int<class_int>` texture, :ref:`Rect2<class_Rect2>` rect, :ref:`Vector2<class_Vector2>` align=Vector2( 0, 0 ), :ref:`float<class_float>` advance=-1 **)**
Adds a character to the font, where ``character`` is the Unicode value, ``texture`` is the texture index, ``rect`` is the region in the texture (in pixels!), ``align`` is the (optional) alignment for the character and ``advance`` is the (optional) advance.

Creates a BitmapFont from the ``*.fnt`` file at ``path``.
.. rst-class:: classref-item-separator
----
.. _class_BitmapFont_method_get_kerning_pair:
.. rst-class:: classref-method
:ref:`int<class_int>` **get_kerning_pair** **(** :ref:`int<class_int>` char_a, :ref:`int<class_int>` char_b **)** |const|
Returns a kerning pair as a difference.
.. rst-class:: classref-item-separator
----
.. _class_BitmapFont_method_get_texture:
.. rst-class:: classref-method
:ref:`Texture<class_Texture>` **get_texture** **(** :ref:`int<class_int>` idx **)** |const|
Returns the font atlas texture at index ``idx``.
.. rst-class:: classref-item-separator
----
.. _class_BitmapFont_method_get_texture_count:
.. rst-class:: classref-method
:ref:`int<class_int>` **get_texture_count** **(** **)** |const|
Returns the number of textures in the BitmapFont atlas.
