.. _class_RDUniform_method_add_id:

.. rst-class:: classref-method

|void| **add_id**\ (\ id\: :ref:`RID<class_RID>`\ ) :ref:`🔗<class_RDUniform_method_add_id>`

Binds the given id to the uniform. The data associated with the id is then used when the uniform is passed to a shader.

.. _class_RDUniform_method_clear_ids:

.. rst-class:: classref-method

|void| **clear_ids**\ (\ ) :ref:`🔗<class_RDUniform_method_clear_ids>`

Unbinds all ids currently bound to the uniform.

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

.. _class_RDUniform_method_get_ids:

.. rst-class:: classref-method

:ref:`Array<class_Array>`\[:ref:`RID<class_RID>`\] **get_ids**\ (\ ) |const| :ref:`🔗<class_RDUniform_method_get_ids>`

Returns an array of all ids currently bound to the uniform.
