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.

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>`.

Method Descriptions
-------------------

.. _class_BitmapFont_method_add_char:

- 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.

----

.. _class_BitmapFont_method_add_kerning_pair:

- void **add_kerning_pair** **(** :ref:`int<class_int>` char_a, :ref:`int<class_int>` char_b, :ref:`int<class_int>` kerning **)**

Adds a kerning pair to the ``BitmapFont`` as a difference. Kerning pairs are special cases where a typeface advance is determined by the next character.

----

.. _class_BitmapFont_method_add_texture:

- void **add_texture** **(** :ref:`Texture<class_Texture>` texture **)**

Adds a texture to the ``BitmapFont``.

----

.. _class_BitmapFont_method_clear:

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

Clears all the font data and settings.

----

.. _class_BitmapFont_method_create_from_fnt:

- :ref:`Error<enum_@GlobalScope_Error>` **create_from_fnt** **(** :ref:`String<class_String>` path **)**

Creates a BitmapFont from the ``*.fnt`` file at ``path``.

----

.. _class_BitmapFont_method_get_kerning_pair:

- :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.

----

.. _class_BitmapFont_method_get_texture:

- :ref:`Texture<class_Texture>` **get_texture** **(** :ref:`int<class_int>` idx **)** |const|

Returns the font atlas texture at index ``idx``.

----

.. _class_BitmapFont_method_get_texture_count:

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

Returns the number of textures in the BitmapFont atlas.
