Property Descriptions
---------------------

.. _class_CharFXTransform_property_color:

.. rst-class:: classref-property

:ref:`Color<class_Color>` **color** = ``Color(0, 0, 0, 1)`` :ref:`🔗<class_CharFXTransform_property_color>`

.. rst-class:: classref-property-setget

- |void| **set_color**\ (\ value\: :ref:`Color<class_Color>`\ )
- :ref:`Color<class_Color>` **get_color**\ (\ )

The color the character will be drawn with.

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

----

.. _class_CharFXTransform_property_elapsed_time:

.. rst-class:: classref-property

:ref:`float<class_float>` **elapsed_time** = ``0.0`` :ref:`🔗<class_CharFXTransform_property_elapsed_time>`

.. rst-class:: classref-property-setget

- |void| **set_elapsed_time**\ (\ value\: :ref:`float<class_float>`\ )
- :ref:`float<class_float>` **get_elapsed_time**\ (\ )

The time elapsed since the :ref:`RichTextLabel<class_RichTextLabel>` was added to the scene tree (in seconds). Time stops when the :ref:`RichTextLabel<class_RichTextLabel>` is paused (see :ref:`Node.process_mode<class_Node_property_process_mode>`). Resets when the text in the :ref:`RichTextLabel<class_RichTextLabel>` is changed.

\ **Note:** Time still passes while the :ref:`RichTextLabel<class_RichTextLabel>` is hidden.

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

----

.. _class_CharFXTransform_property_env:

.. rst-class:: classref-property

:ref:`Dictionary<class_Dictionary>` **env** = ``{}`` :ref:`🔗<class_CharFXTransform_property_env>`

.. rst-class:: classref-property-setget

- |void| **set_environment**\ (\ value\: :ref:`Dictionary<class_Dictionary>`\ )
- :ref:`Dictionary<class_Dictionary>` **get_environment**\ (\ )

Contains the arguments passed in the opening BBCode tag. By default, arguments are strings; if their contents match a type such as :ref:`bool<class_bool>`, :ref:`int<class_int>` or :ref:`float<class_float>`, they will be converted automatically. Color codes in the form ``#rrggbb`` or ``#rgb`` will be converted to an opaque :ref:`Color<class_Color>`. String arguments may not contain spaces, even if they're quoted. If present, quotes will also be present in the final string.

For example, the opening BBCode tag ``[example foo=hello bar=true baz=42 color=#ffffff]`` will map to the following :ref:`Dictionary<class_Dictionary>`:

::

    {"foo": "hello", "bar": true, "baz": 42, "color": Color(1, 1, 1, 1)}

- :ref:`int<class_int>` **get_glyph_flags**\ (\ )

Glyph flags. See :ref:`GraphemeFlag<enum_TextServer_GraphemeFlag>` for more info.

- :ref:`int<class_int>` **get_glyph_index**\ (\ )

Glyph index specific to the :ref:`font<class_CharFXTransform_property_font>`. If you want to replace this glyph, use :ref:`TextServer.font_get_glyph_index()<class_TextServer_method_font_get_glyph_index>` with :ref:`font<class_CharFXTransform_property_font>` to get a new glyph index for a single character.

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

----

.. _class_CharFXTransform_property_offset:

- :ref:`Vector2i<class_Vector2i>` **get_range**\ (\ )

Absolute character range in the string, corresponding to the glyph.

\ **Note:** Read-only. Setting this property won't affect drawing.

If ``true``, the character will be drawn. If ``false``, the character will be hidden. Characters around hidden characters will reflow to take the space of hidden characters. If this is not desired, set their :ref:`color<class_CharFXTransform_property_color>` to ``Color(1, 1, 1, 0)`` instead.
